This taco cauliflower rice casserole is made with ground beef and cauliflower rice-filled layered in between grain-free tortillas! It’s gluten-free, and can easily be made dairy-free and paleo.


  • 1 lb ground beef
  • 1/2 onion, diced
  • 2 tsp garlic powder
  • 1 tsp dried oregano
  • 2 tsp dried cilantro
  • 1 tsp cumin (omit for AIP)
  • 1 tsp salt
  • 1/4 tsp black pepper (omit for AIP)
  • 2 cups cauliflower rice
  • 1 8oz can diced tomatoes (sub 1 cup nomato sauce for AIP)
  • 68 grain free tortillas (I use Siete Almond Flour tortillas, or you can use cassava tortillas for AIP)

For toppings

  • 1/2 cup shredded cheese (dairy-free or omit if desired)
  • 1/4 cup black olives, sliced
  • 2 tbsp red onion, diced
  • 1 avocado, diced
  • 2 tbsp cilantro, chopped
  • 2 tbsp green onion, chopped
  • Lime wedges


  1. Preheat the oven to 375 F and grease a 8×8″ baking dish with oil. Set aside.
  2. Using a large pan, add the beef and diced onion over medium heat. Crumble and brown the ground beef over medium heat, seasoning with salt, pepper, cumin, oregano, and cilantro.
  3. Add the cauliflower rice to the beef mixture once browned and saute for 3-4 minutes before adding the tomato. Stir and simmer for another 3-5 minutes or until the cauliflower rice is tender. Remove from the heat and set aside.
  4. Add one grain-free tortilla to the bottom of the baking dish, and slice another tortilla into strips to cover any open spaces on the bottom of the baking dish. Add about 1/4th of the beef mixture to on top of the tortillas. Repeat, layering tortillas and beef for two more layers, and finishing the casserole with a layer of the remaining beef. Top with shredded cheese if desired.
  5. Transfer to the oven and bake for 12-15 minutes. Serve topped with the toppings of your choice.
