Full recipe and measurements are in the recipe card at the bottom of this post!
Ingredients
- Cauliflower
- Milk: I used canned coconut milk but you can use almond milk, regular milk if you’re not dairy free, etc.
- Avocado oil mayonnaise: I love primal kitchen!
- Arrowroot starch/flour: You could try subbing tapioca flour!
- Nutritional yeast: This adds a cheese-like savory flavor to the recipe and really elevates it! It also packs in a ton of vitamins and protein. Skipping this will definitely take away from the flavor, so if you do, I’d recommend stirring in some real cheese before baking.
- Spices: We use a mix of sea salt, pepper, and red pepper.
- Yellow onion
- Spinach: This is optional but packs in a bunch of extra nutrients and adds a pop of color to the recipe!
- Garlic: A superhero food! Garlic is incredible for you, while also boosting the flavor of the recipe. Don’t leave it out!
- Olive oil: You can sub ghee, coconut oil, or avocado oil.
