How to Make Cheesy Low-Carb Taco Casserole Recipe

Step 1: Prepare Ingredients

Start by thawing the cauliflower rice on the counter if it’s frozen. Drain the Ro-Tel Tomatoes thoroughly to avoid excess liquid that could make your casserole soggy. This prep ensures a perfect texture in the final dish.

Step 2: Preheat Oven and Prepare Casserole Dish

Set your oven to 375 degrees Fahrenheit. Lightly grease a large casserole dish—around 11 by 8 inches—to keep the casserole from sticking and make cleanup easier later on.

Step 3: Cook Onion

Heat 1 tablespoon of olive oil in a frying pan over medium heat. Add the finely chopped onion, cooking until it becomes translucent and starts to develop golden-brown edges. This step builds a sweet, tender flavor base critical to the casserole’s taste.

Step 4: Cook Cauliflower Rice

Add the cauliflower rice to the pan with the cooked onion, increasing the heat to medium-high. Stir occasionally while letting the moisture evaporate. This quick sauté, about 3 to 4 minutes, ensures the cauliflower rice isn’t watery—essential for a casserole with the right consistency.

Step 5: Add Green Onions and Set Aside

Turn off the heat, stir in the sliced green onions for a delicate hint of sharpness, and transfer the cauliflower mixture to a bowl temporarily, freeing the pan for the next step.

Step 6: Brown Ground Beef

Using the same pan, heat the remaining tablespoon of olive oil over medium heat. Add the ground beef, breaking it apart as it cooks until fully browned and no pink remains. This step takes roughly 7 to 8 minutes and lays the meaty foundation of the casserole.

Step 7: Season Beef and Add Tomatoes

Sprinkle in the taco seasoning mix, letting it mingle with the beef for a minute or two to marry the flavors. Then stir in the drained tomatoes and green chiles, warming them through to soften their bright, spicy notes.

Step 8: Combine Cauliflower Rice and Beef Mixture

Return the cauliflower rice mixture to the pan with the beef and tomatoes. Season with salt to taste, and let everything cook together for a few minutes to blend flavors and make sure it is hot throughout.

Step 9: Add Cheese to Mixture

Turn off the heat and stir in 2 cups of the grated Mexican blend cheese, allowing it to melt gently into the warm mixture, creating a creamy, cheesy binding that will carry throughout the casserole.

Step 10: Assemble Casserole

Transfer the cheesy beef and cauliflower mixture to your prepared casserole dish, smoothing it level. Sprinkle the remaining 1 cup of cheese over the top to form a golden, bubbling crust during baking.

Step 11: Bake

Pop the dish in your preheated oven and bake for approximately 30 minutes until the cheese topping is bubbly and turns a gorgeous golden brown. This step sets everything beautifully, inviting your senses to delicious anticipation.

Step 12: Serve

Remove from the oven and let the casserole sit for a few minutes before serving. Consider topping servings with a dollop of sour cream, fresh guacamole, pico de gallo, or sliced avocado for that extra layer of indulgence and freshness.

How to Serve Cheesy Low-Carb Taco Casserole Recipe

Garnishes

Brighten your bowl with fresh garnishes like chopped cilantro, a squeeze of lime, crunchy sliced radishes, or a generous spoonful of salsa. These add texture, brightness, and a refreshing contrast to the creamy casserole.

Side Dishes

Though hearty on its own, this casserole pairs beautifully with a crisp green salad or a side of roasted vegetables. These lighter sides keep the meal balanced and bring complementary textures and colors to your plate.

Creative Ways to Present

For a fun twist, serve the casserole in individual ramekins for a personal touch at dinner parties. Alternatively, scoop portions into low-carb tortillas for quick taco-style meals or scoop onto crunchy lettuce leaves for a light handheld option.

Make Ahead and Storage

Storing Leftovers

Freezing
