  • 3 heads broccoli, chopped into florets about 8 cups
  • 2 cups raw unsalted cashews no need to soak if you have a high-powered blender
  • 1 cup chicken broth sub vegetable broth for vegan
  • 1 cup full fat coconut milk make sure you mix it together before measuring - it separates in the can!
  • 2 tbsp fresh squeezed lemon juice
  • 2 tbsp nutritional yeast
  • 2 cloves minced garlic
  • 1 tsp dijon mustard
  • 1.5 tsp sea salt
  • 1 tsp onion powder
  • ¼ tsp cayenne pepper
  • ½ tsp turmeric


  • 1 cup Pork Panko or regular panko if not gluten free, crushed up paleo crackers, Siete chips, etc.
  • 1 tbsp ghee sub coconut oil or vegan butter for 100% dairy free


  • Preheat oven to 350. Bring a large pot of water to a boil. Add chopped broccoli florets and cook for 3-4 minutes. Drain, and set aside.
  • Make the sauce. Combine cashews, coconut milk, chicken broth, lemon juice, nutritional yeast, garlic, mustard, and spices into a high powered blender. Blend on high for 30 seconds until the sauce is very creamy.
  • Spray a casserole dish (I used 9x9 but you can also use a 9x13 - it will just be a little thinner) with cooking oil. Add broccoli to the casserole dish and pour the sauce overtop. Mix well until combined.
  • Make the topping. Heat the ghee over medium high heat and add in the pork panko (or breadcrumbs/crackers/chips of choice). Saute for 1-2 minutes until combined and slightly toasted. Spread the topping evenly on top of the broccoli mixture.
  • Bake the casserole for 35-40 minutes until cooked through and bubbling on the edges. Serve and enjoy!


Topping: If you want this to be vegan broccoli casserole or just don't want to use pork panko, you can use crushed-up regular bread crumbs (if you tolerate gluten), or crushed-up paleo crackers (I like Simple Mills), or other gluten-free bread crumbs. Or just omit the topping completely.
Cashew Soak: If you don't have a great blender, you'll want to soak your cashews for at least one hour. For best results, soaking overnight is ideal.
