Ingredients You’ll Need

To make this Keto Taco Casserole, you’ll need the following ingredients:

1.5 lbs (680g) ground beef (or ground turkey/chicken for a lighter option)
1 tablespoon olive oil
1 small onion, diced
3 cloves garlic, minced
1 packet (2 tablespoons) taco seasoning (sugar-free for keto)
1 cup salsa (sugar-free for keto)
1/4 cup sliced black olives (optional, for topping)
1 cup shredded cheddar cheese
1 cup shredded Monterey Jack cheese (or your favorite melting cheese)
1/2 cup sour cream (optional, for topping)
1/2 cup diced tomatoes (optional, for topping)
1/4 cup chopped fresh cilantro
1 avocado, sliced (optional, for topping)
1 head cauliflower (or 4 cups cauliflower rice, for the base)

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set it aside for later use.

Step 2: Prepare the Cauliflower Base

If using a whole head of cauliflower, cut it into florets and pulse in a food processor until it resembles rice. Alternatively, you can use pre-riced cauliflower.
Steam or microwave the cauliflower rice for 5-7 minutes until tender. Drain any excess moisture and spread it evenly across the bottom of the prepared baking dish.

Step 3: Cook the Ground Beef

Gently warm the olive oil in a large skillet over medium heat until it glistens.
Sauté the diced onion for 2-3 minutes until it becomes tender and slightly translucent.
Add the ground beef and cook until browned, breaking it into small pieces with a spatula as it cooks.
Stir in the minced garlic and taco seasoning, cooking for an additional 1-2 minutes until fragrant.

Step 4: Assemble the Casserole

Spread the cooked ground beef mixture evenly over the cauliflower rice in the baking dish.
Pour the salsa over the beef layer, spreading it out evenly.
Sprinkle the shredded cheddar and Monterey Jack cheeses over the top.

Step 5: Bake to Perfection

Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly.
For an extra golden crust, you can broil the casserole for 1-2 minutes at the end—just keep a close eye on it to prevent burning.

Step 6: Add Toppings and Serve

Take the casserole out of the oven and allow it to cool for 5-10 minutes before serving.
Top with your favorite toppings, such as sour cream, diced tomatoes, black olives, fresh cilantro, and avocado slices.
Serve warm and enjoy!

Tips for the Perfect Keto Taco Casserole

Drain Excess Moisture: Be sure to drain the cauliflower rice thoroughly to prevent the casserole from becoming watery.
Use Homemade Taco Seasoning: If you don’t have sugar-free taco seasoning on hand, make your own by combining chili powder, cumin, paprika, garlic powder, onion powder, and a pinch of cayenne pepper.
Add Extra Veggies: Feel free to toss in additional low-carb veggies like bell peppers, zucchini, or spinach for added nutrition and flavor.
Make It Spicy: Add a diced jalapeño or a pinch of red pepper flakes to the ground beef mixture for a spicy kick.

Serving Suggestions

This Keto Taco Casserole is a complete meal on its own, but you can pair it with a few side dishes to round out your dinner:

Guacamole: Serve with a side of fresh guacamole for extra creaminess and healthy fats.
Keto Tortilla Chips: Make your own keto-friendly chips using low-carb tortillas for a crunchy accompaniment.
Side Salad: A simple green salad with a lime vinaigrette adds a refreshing contrast to the rich casserole.
