Ingredients for Coziest Tex-Mex Ground Beef Casserole

Gather these ingredients for a dish that promises layers of flavor:

Cooking spray: A must for greasing the casserole dish, preventing sticking.

1.5 lbs ground beef: Choose lean ground beef for a healthier option or 80/20 for more flavor.
2.5 tsp chili powder: Spice it up to your liking; feel free to adjust for heat.
2 tsp onion powder & 2 tsp garlic powder: These add a depth of umami flavor.

1 tsp ground cumin & 1 tsp ground coriander: Earthy spices that are quintessential in Tex-Mex cuisine.
Salt and black pepper to taste: Essential for seasoning controls to enhance flavors.
2 eggs & 2 tbsp heavy cream: These create a rich creaminess that binds the beef layer.

1 tbsp olive oil: Sautéing the onion in this maintains moisture and adds flavor.
1/2 cup chopped onion: Provides sweetness and aroma.
3 tbsp tomato paste: Rich tomato essence that balances the spices.

1 lb frozen cauliflower rice, thawed and drained: A low-carb alternative to traditional rice, offering a healthy twist.
1.5 cups grated cheddar cheese: Go for sharp cheddar for that extra punch; it creates the delicious crust on top.

How to Make Coziest Tex-Mex Ground Beef Casserole

Now let’s dive into the step-by-step process that brings this delightful casserole to your table.

Preheat your oven to 350°F and generously spray a casserole dish with cooking spray.

In a large skillet, brown the ground beef over medium heat until fully cooked. Break it apart with a spatula so that every inch browns beautifully.
Stir in 1.25 tsp of chili powder, 1 tsp of onion powder, 1 tsp of garlic powder, along with the cumin, coriander, salt, and pepper. Let this simmer for a minute or two until fragrant, awakening those wonderful flavors.
In a mixing bowl, whisk together the eggs and heavy cream until smooth. Pour this mixture into the skillet with the beef, stirring until well-combined. Transfer this hearty filling into the greased casserole dish, spreading it evenly.

In the same skillet, heat 1 tbsp of olive oil over medium heat. Add the chopped onion and sauté until softened, about 3-4 minutes. This step infuses richness and depth into your dish.
Stir in the remaining spices and the tomato paste, cooking for another minute. Incorporate the cauliflower rice and allow it to cook for 3-4 minutes, absorbing the delicious flavors.
Mix in 1 cup of grated cheddar cheese, stirring until melted and gooey. Pour this creamy cauliflower mixture over the beef layer, smoothing it out.

Bake in the preheated oven for 25–30 minutes. When you see bubbling edges and the top turns a lovely golden hue, it’s time to take it out.
Top with the remaining cheese and place it back in the oven until melted and enticing.
Allow the casserole to cool slightly before diving in. Prepare for the blend of textures and flavors to sweep you away!

Chef’s Notes & Helpful Tips

Make-ahead tips: You can prepare the casserole a day in advance. Just assemble, cover, and refrigerate. When you’re ready to eat, add 10-15 extra minutes to the baking time.
Cooking alternatives: Try making this in an air fryer for a quicker method. Adjust the time to ensure everything cooks through.
Customization ideas: Want to spice things up? Add diced jalapeños for a kick, or swap out the cauliflower rice with quinoa for a different texture.

Common Mistakes to Avoid

Letting the beef steam: Ensure you brown the beef well in the skillet. This step brings out the flavors. If it steams instead, the beef will be gray and unappetizing.
Not draining the cauliflower rice properly: Excess moisture from the cauliflower rice can make your casserole watery. Squeeze out as much moisture as you can!
Skipping the resting time: Allow your dish to cool for a few minutes before serving. This time helps the layers set and makes for cleaner servings.
