Low Carb Taco Casserole Ingredients
For the Casserole Base

For the Vegetables
- Small Red Bell Pepper – adds a touch of sweetness and crunch; feel free to swap in any colored bell pepper or diced zucchini for variation.
- Small White Onion – enhances the overall flavor through sautéing; yellow onion or shallots can be used for a milder profile.
For the Flavor
- Taco Seasoning – key to rich, taco-inspired flavor; homemade taco seasoning is a wonderful alternative for a personal touch.
- Tomato Paste – enriches the beef mixture with depth; crushed tomatoes give a fresher twist if you prefer.
- Water – helps blend the seasonings with the meat; chicken or beef broth enhances the flavor further.
For the Topping
- Shredded Colby/Jack Cheese – adds a creamy, gooey layer when melted; cheddar or mozzarella cheese can be used based on your preference.
- Sour Cream – lends tanginess and creaminess when served; Greek yogurt is an excellent, healthier alternative.
For Custom Toppings
- Lettuce – adds a fresh crunch; feel free to add your favorites like tomatoes, black olives, or guacamole.
- Cilantro – for a pop of freshness that brightens each bite; jalapeños or hot sauce can kick up the heat, if desired.

Step‑by‑Step Instructions for Low Carb Taco Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This will ensure that when your Low Carb Taco Casserole is ready, it can go straight into a perfectly heated environment, promoting even cooking and that delightful bubbly cheese topping.
Step 2: Sauté the Cauliflower Rice
In a large skillet, heat a drizzle of oil over medium-high heat. Add the frozen cauliflower rice and sauté for 5–7 minutes until it’s nicely browned and heated through. Once ready, transfer the cauliflower rice to a greased 2-quart casserole dish and spread it evenly across the bottom, creating a solid base for your casserole.
Step 3: Brown the Beef and Vegetables
In the same skillet, add the ground beef along with the chopped red bell pepper and diced onion. Cook over medium heat, stirring occasionally, until the meat is browned and the vegetables are tender. This should take about 7-10 minutes. If there’s excess fat, drain it before moving to the next step.
Step 4: Mix in the Seasonings
Once the beef and vegetables are cooked, stir in the taco seasoning, tomato paste, and water. Continue cooking for an additional 3–5 minutes, allowing the mixture to simmer until the liquid is absorbed and all the flavors meld beautifully together, creating a rich filling for your Low Carb Taco Casserole.
Step 5: Assemble the Casserole
Spread the seasoned beef mixture evenly over the cauliflower rice in the casserole dish. Ensure every bit of cauliflower is covered for maximum flavor. Then, sprinkle a generous layer of shredded cheese on top, creating a cheesy, inviting coat that will melt wonderfully in the oven.
Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake for 10-15 minutes, or until the cheese is melted and bubbling with a golden hue. This is the moment to watch for as the enticing aroma fills your kitchen, signaling that your Low Carb Taco Casserole is almost ready to serve.
Step 7: Add Finishing Touches
Once baked, remove the casserole from the oven and let it cool for a moment. Spread a layer of sour cream over the top, allowing it to blend into the cheesy crust. Finally, feel free to add your choice of toppings like fresh lettuce, diced tomatoes, or guacamole before serving, enhancing both flavor and presentation.
How to Store and Freeze Low Carb Taco Casserole
- Fridge: Store leftovers in an airtight container for up to 3 days. Make sure to separate any toppings, such as sour cream or lettuce, to keep them fresh.
- Freezer: Allow the casserole to cool completely before wrapping tightly in plastic wrap or aluminum foil, then freeze for up to 2 months. For best results, reheat from frozen to maintain texture.
