Rosemary–Maple Roasted Nuts
A crisp, sweet-savory fall snack with rosemary, maple, and a clearly separated optional infused adaptation for informed adults.
A little sweet, a little savory, and very much worth making ahead
There is a particular kind of optimism in putting a tray of nuts into the oven before anyone arrives. The kitchen warms. Rosemary becomes woodsy and fragrant. Maple caramelizes around the edges. By the time the first coat is hung by the door, the house already smells like something good is about to happen.
These rosemary–maple roasted nuts are made for that moment. They are crisp, savory, gently sweet, and just spicy enough to keep the bowl interesting. Set them beside sliced apples and sharp cheese, tuck a jar into a host gift, or portion them for a walk along the canal when the leaves have begun to turn.
The base recipe is completely non-infused. For adults who intentionally choose cannabis, an optional infused method is included as a separate adaptation. The two versions should never share an unlabeled bowl.
Why rosemary and maple work
Maple syrup brings more than sweetness. In the oven, it forms a thin glaze that carries salt, pepper, and warm spice across the nuts. Fresh rosemary keeps the recipe from drifting into dessert territory, while orange zest adds a bright note that makes the whole mixture feel distinctly autumnal rather than heavy.
The balance is adjustable. Leave out the cayenne for a quieter bowl, add more black pepper for a savory finish, or use smoked paprika for a deeper campfire note. What matters most is keeping the coating light. Too much liquid can turn roasted nuts sticky instead of crisp.

Ingredients
Base recipe
- 4 cups raw, unsalted mixed tree nuts, such as pecans, almonds, cashews, and walnuts
- 2 tablespoons pure maple syrup
- 1 tablespoon neutral oil or mild olive oil
- 1 tablespoon finely chopped fresh rosemary
- 1 teaspoon finely grated orange zest, optional
- 3/4 teaspoon kosher salt, plus more only after tasting
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon freshly ground black pepper
- Pinch of cayenne pepper or 1/4 teaspoon smoked paprika, optional
For an infused version only
- A legally purchased, clearly labeled cannabis oil or tincture intended for ingestion
- The product package and directions, retained for reference
- The exact quantity determined by the calculation worksheet below
Do not use an unidentified product, an unlabeled homemade infusion, or a product that does not state active-cannabinoid content in usable units. Do not infer finished potency from flower percentage, strain name, or package language such as “full spectrum.”
Instructions
Heat the oven. Position a rack in the center and heat the oven to 325°F. Line a large rimmed sheet pan with parchment paper.
Inspect the nuts. Discard any nuts that appear moldy, shriveled, unusually discolored, or rancid-smelling. Place the remaining nuts in a large mixing bowl.
Make the glaze. In a small bowl, stir together the maple syrup, neutral oil, rosemary, orange zest, salt, cinnamon, black pepper, and optional cayenne or smoked paprika.
Coat thoroughly. Pour the glaze over the nuts. Toss until the nuts look evenly coated and the rosemary is distributed throughout the bowl.
Arrange the tray. Spread the nuts in one even layer. Avoid crowding them into a mound; open space helps moisture escape and encourages crispness.
Roast. Bake for 20–24 minutes, stirring carefully at the 10-minute mark and again near the end. Remove them when the nuts are fragrant, the maple coating looks dry and burnished, and the edges are lightly toasted. Maple can darken quickly, so watch closely during the final minutes.
Cool completely. Leave the nuts on the pan for about 25 minutes. Separate any large clusters with a spatula as they cool. The coating will become crisper as it reaches room temperature.
Choose and label the version. For the standard recipe, transfer the cooled nuts to a container labeled NON-INFUSED. For an infused adaptation, complete the calculation and mixing steps below before portioning and storing.
Optional infused adaptation
First, confirm that the product works for this recipe
Use only a product that:
- Was legally purchased from a licensed source
- Is labeled for ingestion
- States the amount of active THC or other cannabinoid per milliliter, measured serving, or entire container
- Includes directions compatible with the intended preparation method
- Has not expired and has been stored according to its label
If the label does not provide enough information to calculate active cannabinoid content, keep the recipe non-infused.
Choose the mixing method
Method A: Add before roasting only when the label permits heating. Replace part or all of the recipe’s 1 tablespoon of neutral oil with the precisely measured infused oil. Do not increase the total oil beyond 1 tablespoon without retesting the recipe. Mix the glaze exceptionally well and toss repeatedly to encourage distribution.
Method B: Add after roasting when heating is not permitted or unclear. Keep the base recipe non-infused through baking. While the nuts are still slightly warm—but no longer hot—combine the precisely measured infused product with enough neutral oil to make 1 tablespoon total. Toss the warm nuts thoroughly with this mixture, spread them back onto the tray, and allow them to cool completely. This method may produce a softer coating and must be kitchen-tested with the exact product.
Neither method guarantees laboratory-level uniformity. Cannabinoids can distribute unevenly across individual nuts. Treat the calculated amount as an estimate for a thoroughly mixed and evenly divided batch, not as a measurement of any single nut.
Cannabis conversion and calculation worksheet
There is no universal cannabis conversion rate. The calculation depends on the exact product label. Use active THC or the cannabinoid specifically stated on the product—never guess.
Useful kitchen-volume conversions
- 1 teaspoon = 5 milliliters
- 1 tablespoon = 15 milliliters
- 1/2 tablespoon = 7.5 milliliters
- 1/4 teaspoon = 1.25 milliliters
Kitchen spoons and droppers can be inaccurate. For small quantities, use a milliliter-marked oral syringe or another accurate device. Check the product package because a “dropperful” is not a standardized volume.
If the label gives milligrams per milliliter
Total active cannabinoid in the recipe = labeled mg per mL × mL used
Estimated active cannabinoid per serving = total active cannabinoid in the recipe ÷ number of servings
Milliliters needed = desired total batch cannabinoid ÷ labeled mg per mL
If the label gives milligrams for the whole bottle
First calculate concentration:
mg per mL = total active cannabinoid in the bottle ÷ total bottle volume in mL
Then use the formulas above.
If the label gives milligrams per measured dropper or serving
Confirm the exact volume of that labeled measure. Then calculate:
Total active cannabinoid used = mg per labeled measure × number of complete or partial measures used
For a partial measure, convert the quantity to milliliters rather than estimating by eye.
Worked example for demonstrating the math—not a serving recommendation
Suppose a product label states 2 mg active THC per mL and a recipe developer measures 8 mL into a batch divided into 16 equal servings:
- 2 mg/mL × 8 mL = 16 mg estimated active THC in the full batch
- 16 mg ÷ 16 servings = 1 mg estimated active THC per serving
This example explains arithmetic only. It is not individualized dosing advice and does not establish that 1 mg—or any other amount—is appropriate for a particular person.
Infused Rosemary–Maple Roasted Nuts
- Cannabis product used: North Lake Supply Midnight Snack RSO
- Package size: 1.0g
- Labeled concentration: 77.75% THC
- Estimated THC in complete syringe: 777.5 mg
- RSO used in this recipe: Approximately 0.206 g
- Infused maple syrup: 2 tablespoons pure maple syrup
- Coconut oil added: 1 tablespoon, melted
- Estimated batch total: Approximately 160 mg THC
- Verified serving count: 16 equal portions
- Estimated THC per serving: Approximately 10 mg
- Calculation: A product containing 77.75% THC contains approximately: 1,000 mg RSO × 0.7775 = 777.5 mg THC per 1.0 g syringe
- The recipe needs approximately 160 mg THC for 16 servings: 10 mg THC × 16 servings = 160 mg THC needed. The corresponding amount of RSO is: 160 mg ÷ 777.5 mg per gram = 0.2058 g RSO.
- Rounded measurement: Use approximately 0.206 g—or 206 mg—of Midnight Snack RSO. Final per-serving estimate: 160 mg THC ÷ 16 servings = approximately 10 mg THC per serving
- Because maple syrup is water-based and RSO is oil-based, do not attempt to dissolve the RSO directly into the maple syrup.
- Melt 1 tablespoon of coconut oil over very low heat. Remove it from the heat as soon as it becomes liquid.
- Using a scale accurate to at least 0.001 g, measure approximately 0.206 g of Midnight Snack RSO. Do not estimate the quantity visually or convert it to milliliters without verified product-density information.
- Stir the measured RSO into the melted coconut oil until completely dispersed and no visible streaks remain.
- Whisk the infused coconut oil into 2 tablespoons of maple syrup. Continue whisking until the glaze appears as uniform as possible.
- Add the rosemary, orange zest, salt, cinnamon, black pepper, and optional cayenne or smoked paprika.
- Toss the glaze thoroughly with 4 cups of mixed nuts, repeatedly scraping the bottom and sides of the bowl.
- Only roast the infused glaze if the product’s packaging or manufacturer directions permit heating. Otherwise, the recipe must be retested using a compatible post-roasting method.
- Once finished, mix the entire batch again, weigh it, and divide it into exactly 16 equal portions by weight.
- The labeled 77.75% represents active THC
- Exactly 0.206 g of RSO is transferred
- The finished batch is mixed thoroughly
- No meaningful THC is lost during preparation
- The batch is divided into exactly 16 equal portions
- CANNABIS-INFUSED — ESTIMATED 10 MG THC PER SERVING — ADULT USE ONLY
- Weigh the entire finished batch in grams, excluding the container.
- Divide that weight by the verified number of servings.
- Weigh each serving individually.
- Package each serving separately and apply the same clear infused-food label to every portion.
- Place each measured portion in a sealed, clearly labeled container.
- Label it CANNABIS-INFUSED — ADULT USE ONLY — DO NOT SHARE.
- Include the product used, preparation date, estimated active cannabinoid per serving, serving size, and the potency warning below.
- Store it securely, locked when practical, and completely away from children, pets, and anyone who has not knowingly chosen cannabis.
- Keep it physically separate from non-infused food.
- Follow the cannabis product’s storage directions. If those instructions require refrigeration, refrigerate the finished food.
- Do not store an infused batch in an ordinary nut jar, decorative bowl, or reused package that could be mistaken for conventional food.
- Allergen notice: This recipe contains tree nuts. Verify every ingredient label for other allergens and cross-contact information.
- Raw versus roasted nuts: Begin with raw, unsalted nuts so the seasoning and final browning remain under control.
- Rosemary: Chop it finely; large needles can feel tough after roasting.
- Maple: Use pure maple syrup rather than maple-flavored pancake syrup for predictable consistency.
- Cooling: Do not seal the container until the nuts are fully cool. Trapped steam softens the coating.
- Gifting: Gift only the non-infused version unless every recipient is a consenting adult and the packaging, labeling, possession, transfer, and other applicable rules have been reviewed. The safest editorial recommendation is to gift only non-infused food.

Infusion instructions
Required caution
Using the entire 1.0 g syringe would produce approximately 777.5 mg THC in the batch, or approximately 48.6 mg per serving across 16 servings. That is substantially above the intended target.
The 10 mg estimate also assumes:
Cannabinoid estimates depend on the labeled potency of the product used, preparation method, portion size, and even distribution. Individual results may vary.
Label each portion:
Store securely away from children and pets, prevent accidental sharing, and do not drive or operate machinery after consumption.
A regulatory ceiling is not a personal recommendation
New Jersey rules state that each single serving of a commercially sold cannabis product may contain no more than 10 mg of active THC, and a package of finished ingestible product may contain no more than 100 mg. Those figures are regulatory maximums for products sold in the state; they are not a suggestion that a homemade serving should contain 10 mg. Individual responses vary, and homemade mixing introduces additional uncertainty.
When making informed adult choices, follow the purchased product’s directions and warnings. Do not use this recipe as medical treatment or personalized dosing guidance.
Portioning matters
For the base recipe, 1/4 cup is a convenient snack portion. For an infused version, volume is less reliable than weight because mixed nuts vary in size and density. After the finished batch is completely mixed and cooled:
Even careful weighing cannot prove that active cannabinoids are perfectly uniform throughout the batch. It only helps divide a well-mixed batch more consistently.
Make them your own
Orange and black pepper
Use the optional orange zest and increase black pepper to 3/4 teaspoon for a bright, savory version.
Smoky rosemary
Add 1/2 teaspoon smoked paprika and omit the cinnamon. This version works especially well beside aged cheddar and sliced pear.
Warm spice
Add a pinch each of ground ginger and nutmeg. Keep both restrained so the rosemary remains recognizable.
No heat
Omit cayenne and smoked paprika. The maple, rosemary, and black pepper still provide plenty of contrast.
One-nut version
Use four cups of pecans, almonds, cashews, or walnuts. Check roasting early because different nuts brown at different rates.
If changing the yield of an infused recipe, recalculate the complete batch and per-serving estimates. Never assume potency stays the same after changing the number or size of servings.
A small fall ritual: make one bowl, label it well
Roasted nuts are social food. People reach for them without much thought, which is exactly why an infused bowl requires more structure than a casual handwritten note placed somewhere nearby.
If cannabis is included, portion the recipe before guests arrive. Keep the infused servings in their own clearly marked container, physically separated from ordinary snacks. Tell every adult what the food contains before it is offered. Never place infused food on a shared grazing table, and never allow it to be passed around without its label.
The simplest hosting choice is also the safest: serve the rosemary–maple nuts non-infused and let adults make any separate cannabis choice using its original packaging and directions.
Storage and labeling
Non-infused version
Once completely cool, store the nuts in an airtight container in a cool, dry place. For best texture and flavor, use within one week unless the final kitchen test supports a different quality window. Refrigeration can extend quality, but allow the nuts to return to room temperature in a closed container to limit condensation.
Infused version
Discard the nuts if they develop mold, moisture, an unusual odor, or a rancid taste. Do not taste food to determine whether suspected spoilage is safe.
Required potency warning
Cannabinoid estimates depend on the labeled potency of the product used, preparation method, portion size, and even distribution. Individual results may vary.
Responsible-use notice
This optional adaptation is for adults of legal age only. Purchase cannabis only from licensed sources and remain within applicable purchasing and possession limits. Follow the product label and directions. Keep cannabis and infused food securely stored away from children and pets. Clearly label every infused item and prevent accidental sharing. Do not drive, operate machinery, or perform safety-sensitive activities after consuming cannabis. Do not combine cannabis with alcohol or other substances without understanding the risks. If you take medication, are pregnant or breastfeeding, have a serious medical condition, or have questions about personal risk, consult a qualified healthcare professional rather than relying on a recipe.
