Tips for Choosing Cheese Variants
Cheese plays a big role in this dish. Here’s how to pick the best types:

These tips will help you make a tasty casserole that everyone will love.

Step-by-Step Instructions

– 1 pound ground beef (or turkey)
– 1 small onion, finely diced
– 2 cloves garlic, minced
– 1 packet taco seasoning (ensure it’s sugar-free)

– 2 large eggs
– Salt and pepper to taste

Make sure you have everything ready. This will help you move fast in the kitchen and keep things fun.
Cooking the Meat and Vegetables
In a large skillet, add the ground beef or turkey and the diced onion. Cook this over medium heat. Stir often until the meat is brown and the onions are soft. This should take about 7-10 minutes. If there is extra fat, drain it carefully.
Next, add the minced garlic and taco seasoning to the skillet. Mix it well and let it cook for about one minute. Then, stir in the well-drained diced tomatoes. Let this simmer for about 5 minutes. This makes sure all the flavors blend together nicely.
Assembling the Casserole Layers
In a large mixing bowl, mix the cauliflower rice, half of the shredded cheddar cheese, half of the mozzarella cheese, and the two beaten eggs. Stir until everything blends well. Season this mixture with salt and pepper to taste.
Now, grease a 9×13-inch baking dish lightly. Spread the cauliflower rice mixture evenly across the bottom. This will be the base of your casserole.
Next, layer the seasoned meat mixture on top of the cauliflower layer. Then, sprinkle the diced bell pepper and optional jalapeño slices over the meat. This adds great flavor and texture.
Finally, top everything with the remaining cheddar and mozzarella cheeses. Place the dish in the preheated oven and bake for 25-30 minutes. Look for the cheese to be melted, bubbly, and golden brown on top.
Once it’s done, take it out and let it cool for a few minutes. Slice it into squares for serving. Add fresh cilantro on top and serve with optional sour cream and avocado slices. Enjoy your Keto Taco Pizza Casserole!
Tips & Tricks
How to Make It Extra Cheesy
To boost the cheese factor, use a mix of cheeses. I love mixing cheddar and mozzarella. Try adding cream cheese for richness. You can also sprinkle some Parmesan on top before baking. This gives a nice crust and extra flavor. Don’t be shy with the cheese!
Alternatives for Cauliflower Rice
If you’re not a fan of cauliflower rice, try other options. Riced broccoli or zucchini can work well too. Shredded cabbage is a great low-carb choice. Each of these swaps gives a different texture and taste. Experiment to find your favorite!
Adjusting Spiciness Levels
You can control the heat in this dish easily. Start by adding less jalapeño if you want it mild. If you enjoy spice, add more jalapeños or even some crushed red pepper. You can also serve hot sauce on the side for guests. This way, everyone can enjoy their perfect level of spice.
Pro Tips
- Use Fresh Ingredients: Always opt for fresh vegetables and high-quality meats to enhance the flavor and nutritional value of your casserole.
- Customize the Heat: Adjust the amount of jalapeño or add a pinch of cayenne pepper for extra spice, depending on your heat preference.
- Make it Ahead: Prepare the casserole in advance and refrigerate it. This allows the flavors to meld and can be baked right before serving.
- Rest Before Serving: Allow the casserole to sit for a few minutes after baking. This helps it set and makes it easier to cut into neat squares.
Variations
Vegetarian Option
You can easily make a vegetarian version of this casserole. Instead of ground beef or turkey, use 1 pound of black beans or lentils. Cook them with the onion and garlic just like the meat. You can also add more veggies, like zucchini or mushrooms, for extra taste. This keeps the dish filling and flavorful while staying keto-friendly.
Using Different Proteins
Feel free to switch up proteins for variety. Ground chicken or pork works well in this dish. You can also use shredded rotisserie chicken. Just make sure to adjust the cooking time to avoid drying out the meat. Each protein will bring its unique texture and flavor, making it fun to try different options.
Gluten-Free Modifications
The recipe is naturally gluten-free, but always check your taco seasoning and other ingredients. Some brands add gluten. To ensure your casserole stays gluten-free, use fresh or frozen cauliflower rice, and confirm that your cheese is also gluten-free. This way, everyone can enjoy this tasty dish without worry.
