Cheesy Cauliflower and Crispy Steak Casserole (Dairy Free, Keto, Paleo, Whole30)

Keto casseroles are a thing, people! This dairy free keto casserole is inspired by mac and cheese… and steak! Made with a dairy free, nutritional yeast sauce and marinated skirt steak I guarantee this keto casserole will be a family favorite. 

Bonus, I’ve made it so this baby can be EASILY made AIP compliant (autoimmune protocol). It’s already nut and dairy free but does have some seed-based spices. Ever since my AIP Keto Reset program went live, I see the need for more recipes in this area. It’s a struggle because this blog has always chronicled my own personal healing journey and I have had a lot of successful reintroductions (eggs, seeds, nuts, coffee, chocolate-praise Jesus!)

However, I live to help you all! So I will continue to focus on NUT FREE, NIGHTSHADE FREE KETO RECIPES, with AIP modifications… much like my book… Made Whole (shameless plug).

Dairy Free Keto Casserole Variations 

Coconut Free/ Extra Cheesy: Use cashew cream (recipe here) instead of coconut cream.  Halve the bone broth, double the cream. Add a splash of fish sauce. 

AIP compliant: Omit the mustard and black pepper. Add in 1 tablespoon granulated garlic. 

Make it a bake: Add 2 whisked eggs to the cheese sauce base. this will bake up firm for a casserole you can slice and serve. 

If you can’t find skirt steak: You can use hangar steak, flap meat or sirloin steak. 

All these variations sound amazing, right? They are! But the original recipe for this dairy free keto casserole is amazing too. 

Simple, clean flavors. Easy to make. Hearty an comforting. This creative recipe is perfect for getting you out of your food rut!

  1. Just made this for dinner and everyone Liked it, including the 5 year old. I used rib steak and added Broccoli for more veggies. I didnt have arugula, so skipped that. Sad. My onLy complaint, if you want to call it that, is that my cauliflower was a bit softer than i would have preferred. I think adding the beef and cheese Sauce at the 25 minute just to broil would have worked best for me. Love your creativity in the kitchen, cristina. You make some very unusual dishes but after trying seVeral, i have grown to trust you-even if it sounds wacky. you haveN’t let me down yet!

  2. im not sUre if i missed something.. 1 tb of vinegar and 1 tsp of aminos didnt make MariNade.. was there something else i needed to add?

    1. I’m not sure the question…. you just toss the steak strips in salt, red wine vinegar and coconut aminos to marinate then for a few minutes before cooking…
