  • Olive Oil – Extra-virgin olive oil is great because it is delicious and versatile.
  • Cannabis Flowers – You will need your desired amount of cannabis flowers, ranging from 3.5 grams up to 1 ounce. Use this ratio guide to determine how much flower to oil to use. Choose THC, CBD, or CBG flower. You can purchase from my online shop here.
  • Lecithin, optional: If you’re new to working with lecithin, you can learn more about adding lecithin to edibles here. If needed, you can purchase liquid lecithin or powdered lecithin. This ingredient is optional.

Note: a complete list of ingredients with amounts and printable instructions is located in the recipe card below.

The Step-by-Step Process

  • Step 1 Create a water bath that stays at approximately 180-190° F. The printable instructions below are for using a crockpot.
  • Step 2 – While the water bath is heating, measure and decarb your cannabis flower. Use my traditional oven or Instant pot decarboxylation tutorials, if needed. 
  • Step 3 – Evenly add the decarbed flower and olive oil to the mason jars you plan on using. If you plan on using lecithin, add it now.
  • Step 4 – Place the jars into the water bath. Place the lid on the crockpot and leave it alone to infuse for 4 hours. After 4 hours, remove the jars from the water and allow them to cool.

The Step-By-Step Process

  • Step 5 – Set up a straining station to separate the plant matter from the oil. Options include a paper filter and funnel, cheesecloth, French press, or a simple coffee filter.
  • Step 6 – Strain the oil . You can save the leftover cannabis pulp for use in future recipes.
  • Step 7 – Return the prepared oil to whatever jar you would like to store it in; a mason jar works well.
  • Step 8 – Store the oil in a cool, dry place. It will last longer if stored in the refrigerator and even longer if stored in the freezer.

Cannabis Olive Oil

Olive Oil For Good Health

Extra-virgin olive oil (EVOO) is widely known as one of the world’s healthiest oils (1).

So much so that people tend to live longer and healthier lives in areas where olive oil is a staple part of the diet. 

Like hemp seeds and hemp seed oil, EVOO has a high percentage of omega-3 fatty acids. According to the FDA, having two tablespoons of EVOO daily may reduce your heart disease risk (2). 

EVOO is also extremely rich in antioxidants. It contains polyphenols which act as antioxidants by reducing oxidative stress throughout your body.

Antioxidants also aid in strengthening your immune system, making your body more resistant to infections and inflammation (3). 

Notes & Expert Tips

Below is a general guideline explaining the most important steps you need to take to make cannabis olive oil at home.

Decarb First

To reap the benefits of CBD or THC, you must decarboxylate the cannabis before combining it with the oil. This process is as simple as heating it in the oven.

For this recipe, we decarb our cannabis flower in the oven before combining it with the olive oil and placing it into the crockpot. Therefore, we can have a shorter infusion time, a total of four hours.

If you’re brand new to the process of decarboxylation, start with my guide for decarbing in an oven or an Instant Pot.

Consider the Strain You’re Using

Each cannabis strain contains varying amounts and ratios of different cannabinoids and terpenes

Because each cannabinoid and terpene decarboxylates at a different temperature, you will want to consider the best temperature and cooking time for your particular strain. 

Additionally, the final potency and intoxicating effects will vary depending on THC or CBD dominant strain.

The Freshness of Product

You notice differences in your final product depending on the freshness of the material you start with.

You can use traditionally dried and cured flower, raw flower buds or trim. If you use raw trim, just know your final product will look and taste more green, due to the extra chlorophyll.

The potency will vary with the freshness of the material, the cannabinoid concentration, and how much you ultimately use.

Save The Leftover Pulp

After the straining process, you will be leftover with a ball of spent cannabis flower, also called leftover pulp or sludge

While some folks say it is garbage and throw it away, I’ve heard too many success stories of people using the pulp with great results.

Anecdotally, many members of my Well With Cannabis Community have reported still receiving pleasant, intoxicating high effects when consuming the pulp.

This supports the theory that at least some percentage of cannabinoids are left behind in the plant matter. 

I believe in both nutrition and sustainability, so I recommend keeping your leftover pulp to use in any one of these 15 ways to use leftover cannabis pulp.

Frequently Asked Questions

Below are some of the most frequently asked questions I get asked about making cannabis-infused olive oil that wasn’t addressed above.

Can I infuse olive oil with FECO or RSO?

Yes, you can infuse olive oil with FECO or RSO. I recommend mixing 1mL of FECO with 29mL of olive oil for a strong batch, but you can choose to mix 1mL FECO with your desired oil amount.

Can I make a smaller batch of EVOO?

Yes, you can easily scale this recipe to a smaller size to meet your needs. Simply use this cannabis flower to oil ratio guide to help you decide how much to infuse. The process of infusion will remain the same regardless of how much you use.

Learn how to make a delicious cannabis olive oil at home with just a crockpot or slow cooker. This recipe is perfect for anyone who wants to learn how to make a dairy-free, plant-based cannabis oil that can be used in many different recipes.
Prep: 30 minutes
Cook: 4 hours
Total: 4 hours 30 minutes
Servings: 16 ounces



  • Lay a clean tea towel down on the bottom of the crockpot. This will create a buffer between your mason jars and the crockpot, potentially preventing any jar from moving or cracking during cooking. Fill your crockpot with enough warm to hot water to cover the top of the mason jars you plan on using by an inch to create a water bath.
  • Place the digital instant-read thermometer into the water. Start the crockpot heat on high. When a temperature of 185° F is reached, turn the crockpot to low.
  • While the water bath is heating in the crockpot, measure and decarb the cannabis flower according to the appropriate decarb time and temperature.
  • Evenly divide the olive oil between the mason jars you plan on using. You can either use pint-sized or half-pint-sized jars, it's you're preference, just be sure they fit in your crockpot. No matter the size, be sure to leave a 1/2 inch headspace from the top.
  • Evenly divide the decarbed flower between the olive oil-filled jars. Wipe the rim of the jars with a clean towel and place the lid on. Tighten the metal ring to finger-tip tightness; it does not have to be tightened all the way. Do not tighten too tightly.
  • Once the water bath reaches a temperature of 185° F, carefully place the jars into the water bath. Place the lid on the crockpot and leave it alone to infuse for 4 hours.
  • After 4 hours, carefully remove the lid, followed by the jars from the hot water. Set them aside to cool.
  • Once cool enough to handle, you will want to strain the oil through a paper filter and funnel, cheesecloth, or French press to separate the plant-matter from the olive oil.
  • Save the leftover cannabis pulp for use in future recipes. Then return the prepared cannabis olive oil to whatever jar you would like to store it in.
  • Store the prepared cannabis olive oil in a cool, dry place. It will last longer if stored in the refrigerator and even longer if stored in the freezer.


  • Yield: ~16 ounces / ~2 cups. You can make a smaller batch by following this ratio guide.
  • Temperature control: The water bath does not need to stay perfectly at 185° F  the whole time. Any temperature between 170°-190°F is OK.
  • Safety: Sanitize your jars by keeping them submerged in the 185° F crockpot for 10 at least minutes. This step is not necessary, but good practice.
  • Floating jars: The mason jar may float when placed in the water bath. Simply put something heat and water safe over the top of the jar to weigh it down, a clean rock works well.
  • Alternative carrier oil options include: avocado oil, hemp seed oil, grape seed oil, coconut oil

  1. Can I put leaves and stems in crockpot without the mason jar? I use coconut oil and will cook for
    Eight hours. Then use a cheese cloth to strain. Will this have a lot of thc? I want to make brownies and cookies

  2. 5 stars
    Excellent recipe. I am going to use it to make something I can just take a tsp of in the evening to help me sleep. What on earth do you do with the infusion poo that is left over? It must have lots of medicine left in it and I hate to waste it.

  3. Good day Emily and thanks for your recipes!!! I have a modified one, perhaps others would like it as well as it removes the need to filter, and leaves you with some left overs you can place in gel caps too. I decarb in the oven as you indicated, but before doing so open up a teabag, empty the contents and replace with the cannabis; saving the tea for a tea dropper later. Then I the place two staples in the tea bag to seal it after folding it over, and proceed with decarb. After decarb you can add your oil or your transferring agent if will and do either the crock pot or instant pot method to infuse. Note I have found that the low setting on crockpot for 8 hours does a better job as far as potency, but both work. The tea bag method eliminates the need to filter requirement and we have had great success with this method.

    The other method is to simply sift your cannabis to a finer consistency, then decarb it per your instructions. Simply let it cool, and place in gelatin capsules, and she takes them directly; just as you would place it in brownies…etc. Since my wife suffers from advanced neuropathy this method works well if we require a quicker treatment. Thanks as always we could never have seen her pain free without your guidance, also thanks for the MCT advice too.

  4. Hi there, Brad. Thank you so much for sharing your modified recipe and methods with us! It’s fantastic to hear from readers who have found creative ways to make the process easier and more efficient. Your tea bag method sounds very interesting – a great way to avoid filtering and make use of every bit of the cannabis 😄 Your alternative method of using sifted cannabis in gelatin capsules is also an innovative approach, and I’m thrilled to hear it’s providing quick relief for your wife’s neuropathy. Your feedback not only helps me, but also our entire community, and I’m sure many will find your feedback helpful. Thank you for being a part of our journey and for your kind words. It’s wonderful to know that the advice and recipes have been beneficial for you and your wife.
