Ingredient Notes

Ingredients needed to make beef taco skillet gluten free.
  • Ground beef. Or try this casserole with ground turkey instead.
  • Jalapeno. Make sure to seed and dice your pepper. For a more mild taco casserole, use less jalapeno.
  • Taco Seasoning. My Homemade Taco Seasoning is perfect in this recipe. If using store bought seasoning, check the label to ensure there are no added sugars.
  • Riced cauliflower. This is raw cauliflower chopped into tiny rice-sized pieces. Find it fresh or frozen at most grocery stores. Or learn how to make riced cauliflower with our easy tutorial!

Tips and Tricks

  • Toppings: Serve this Beef Taco Casserole with any taco toppings you like. We love it with guacamole, sour cream, olives and cilantro.
  • Use freshly grated cheese. For smooth melting and best flavor, buy cheese in blocks and shred it at home.
  • Storing. Cover leftovers tightly and store in the fridge for up to 4 days. Rewarm in the oven or microwave before serving.
  • IF on a keto diet, cut back the beans, corn, and tomatoes.

Recipe FAQs

Is this Taco Casserole spicy?

That depends on your taste buds. It has a bit of a kick but is far from overwhelmingly spicy. Amp up the spice by serving the casserole with hot sauce or salsa for topping.

What can I use instead of Rotel tomatoes?

If you can’t find Rotel tomatoes, look for another brand of diced tomatoes with green chilies. In a pinch, you can substitute plain diced tomatoes too! To replicate the spiciness of Rotel, add a bit more jalapeno or a dash of red pepper flakes.

Can I use frozen riced cauliflower in this recipe? Do I have to thaw it first?

You can add frozen riced cauliflower directly to the casserole dish in this recipe. No need to thaw first.

What side dishes go well with Beef Taco Casserole?

This casserole can be a full meal on its own! Serve it with a simple side salad or sliced veggies. It’s also delicious with a side of tortilla chips for scooping up bites of casserole.
