Ingredient Notes
- 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!
- Shredded cheese. We used cheddar. A Mexican cheese blend would be delicious here too. Shred your own cheese for best results!
Cooking Instructions
Start by browning the ground beef.
Cook the beef in a large skillet with diced onion and jalapeno. Drain off the grease, then stir in the taco seasoning and water.
Assemble the casserole:
Layer ground beef in a 2 quart casserole dish with black beans, corn, cheese, Rotel tomatoes and riced cauliflower.
Bake:
Cook the casserole uncovered in a 350 F oven for 15 minutes. Serve hot with your favorite toppings!
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
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.
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.
You can add frozen riced cauliflower directly to the casserole dish in this recipe. No need to thaw first.
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.
