Cannabis Cooking Oil

Cannabis Cooking Oil Recipe: CBD, CBG & THC Infused Olive or Coconut Oil

By Mellow Moose | Updated 08/24/2026

Quick Answer

Cannabis cooking oil is olive or coconut oil with cannabinoid isolate dissolved directly into it — no flower, no straining, no smell. Using 2.5g of CBD or CBG isolate in 2 cups of oil, the finished batch carries ~2,425mg of cannabinoids — roughly 76mg per tablespoon. Total time is about 45 minutes, no decarboxylation needed with CBD or CBG isolate.

Why Make Cannabis Cooking Oil?

Infused oil is the most versatile savory infusion in the kitchen: dressings, marinades, sautés, pasta finishes, roasted vegetables, popcorn. Where cannabutter locks you into butter-friendly recipes, oil goes everywhere — and the isolate method means it looks, smells, and tastes like plain oil, with none of the green flavor of flower infusions.

Because you start from ≥97% pure, third-party-tested isolate (COAs here), the dose per tablespoon is known to the milligram — about $7.50 of a 20g CBD isolate jar per 2-cup batch.

Recipe Overview

• Yield: 2 cups infused oil (32 tablespoons)
• Prep time: 15 minutes
• Cook time: 30 minutes
• Difficulty: Beginner

Equipment

• Double boiler
• Stirring spoon or spatula
• Mason jar with lid
• Kitchen scale that reads to 0.1g

Ingredients

• 2.5g CBD Isolate or 2.5g CBG Isolate — or, for the THC version, 1g of a THC source: THCa isolate (decarbed first), THC distillate, or another dabbable extract (see the THC section below)
• 2 cups cooking oil — olive for dressings and light cooking, coconut for sautéing and baking

Instructions

1. Fill the bottom of a double boiler with water and bring to a gentle simmer.
2. Add the cooking oil to the top section and let it warm.
3. Slowly add the isolate (or already-active THC source), stirring gently until fully dissolved — the oil should stay completely clear.
4. Continue on low heat for ~30 minutes, stirring occasionally, to guarantee full incorporation.
5. Remove from heat, cool, and transfer to a sealed glass jar.
6. Label it (cannabinoid + mg per tablespoon) and store in a cool, dark place.

Dosage Math

CBD or CBG version: 2.5g isolate at ≥97% purity ≈ ~2,425mg per 2-cup batch

• ~76mg per tablespoon
• ~25mg per teaspoon

THC version: 1g of decarbed THCa isolate or ~85% distillate ≈ ~850mg per batch

• ~26.5mg THC per tablespoon
• ~8.8mg THC per teaspoon

The dose divides by your recipe's servings: a vinaigrette using 2 tablespoons of THC oil split across 4 salads is ~13mg per plate — full-strength edible territory. Run your dish's per-serving math in the Edible Dosage Calculator before serving, and remember infused meals are edibles: 45–120 minute onset, wait 2 hours before more.

The THC Version — Pick Your Source

• THCa isolate (~97%+) — needs decarb. Bake 1g at 240°F for 30–40 minutes until the bubbling stops, cool, then dissolve into the warm oil. Converts at ~87.7%: 1g → ~850mg active THC.
• THC distillate (~85–90%) — already active. Straight into the warm oil. 1g at ~85% → ~850mg — identical math.
• Other dabbable extracts (~75–80%) — decarb first unless labeled activated. 1g at ~78% after decarb → ~680mg (~21mg per tablespoon), with noticeable cannabis flavor in delicate dishes.

THC oil safety: infused oil is indistinguishable from regular oil on the counter. Label the jar clearly and store it away from anyone under 21 and from pets — and never cook with it for guests without telling them exactly what's in the dish.

Heat & Cooking Guidance

• Safe zone: dressings, drizzles, low-and-medium-heat sautés, and standard baking all preserve potency well.
• Watch the smoke point: extra-virgin olive oil smokes around 375°F, refined coconut around 400°F — and sustained temperatures above ~320°F begin degrading cannabinoids regardless of the oil. Practically: sauté and bake freely, but don't deep-fry or sear at max heat with your infused oil. Use plain oil for the sear and finish with the infused oil.
• Best-practice move: treat infused oil as a finishing oil where possible — added after cooking, potency is fully preserved and dosing stays exact.

Ideas for Using Cannabis Oil

• Popcorn ("potcorn"): drizzle over freshly popped corn with salt.
• Hummus: blend chickpeas, tahini, lemon, and garlic, then stream in the infused oil.
• Pesto: use infused olive oil as the base for a rich finishing sauce.
• Vinaigrette: whisk with vinegar, mustard, salt, and pepper.
• Roasted vegetables: toss carrots, potatoes, or onions with the oil and herbs before a 400°F roast — brief bake times at that range are fine.

Common Failure Modes

• Crystals at the bottom of the jar. Normal in cool storage — the isolate recrystallizes. Warm the jar gently and stir; it redissolves with no potency loss.
• Cloudy coconut oil. That's just coconut oil solidifying below ~76°F — cosmetic, not a problem.
• Uneven doses between uses. Give the jar a stir or gentle swirl before measuring, especially if crystals appeared.
• Faint cannabis flavor in a delicate dish. You used a dabbable-extract THC version — isolate and distillate are nearly flavorless; raw-extract infusions aren't.

FAQs

What is cannabis-infused cooking oil? Ordinary cooking oil with cannabinoids — CBD, CBG, or THC — dissolved directly into it, ready for cooking, dressings, or drizzling, with a precisely known dose per tablespoon.

Do I need to decarboxylate? Not for CBD or CBG isolate. THCa isolate and most raw dabbable extracts must be decarbed first (240°F, 30–40 minutes); distillate is already active. Flower always needs decarbing — but this recipe skips flower entirely.

What oil works best? Olive for dressings, finishing, and light cooking; refined coconut for sautéing and baking (higher smoke point, solid at room temperature). Avocado oil also works well for higher-heat cooking.

Can I cook at high heat with it? Standard baking and sautéing, yes. Avoid deep-frying and max-heat searing — sustained temperatures above ~320°F degrade cannabinoids, and above each oil's smoke point you're damaging the oil itself. When in doubt, finish with it instead of cooking in it.

Can I combine cannabinoids? Yes — a 50/50 CBD + CBG batch (1.25g each) is a popular balanced blend, and the math stays the same per total grams.

How long does it last? Up to 6 months sealed in a cool, dark place; refrigeration extends it (expect harmless clouding or solidifying with coconut oil).

Is infused cooking oil legal? Hemp-derived CBD and CBG oil made from federally compliant isolate (≤0.3% Delta-9 THC by dry weight) is legal federally and in most states. Our isolates — including our THCa isolate — are federally compliant hemp-derived products. Check your state's rules for any THC version.
