Step‑by‑Step Instructions for Best Low Carb Taco Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This crucial step ensures that your Best Low Carb Taco Casserole cooks evenly and reaches that perfect golden-brown crust. While the oven warms up, you can assemble your other ingredients, allowing for a seamless cooking experience.

Step 2: Cook the Ground Beef
In a large skillet over medium heat, add the ground beef, breaking it up as it cooks for about 7-10 minutes until browned. Stir occasionally to prevent sticking and ensure even cooking. Once browned, drain any excess fat to keep the casserole lighter and healthier, making it perfect for your low-carb lifestyle.

Step 3: Season the Beef
Next, stir in the taco seasoning along with the diced tomatoes and green chiles. Allow this mixture to simmer for about 5 minutes, stirring occasionally. During this time, the flavors will meld beautifully, creating a flavorful base for your taco casserole that everyone will love.

Step 4: Assemble in Baking Dish
Carefully transfer the seasoned beef mixture into a greased 9×13-inch baking dish, spreading it evenly. This will provide a solid foundation for the luscious toppings that follow in your Best Low Carb Taco Casserole, ensuring each bite is packed with flavor.

Step 5: Mix Eggs and Sour Cream
In a separate bowl, whisk together the eggs and sour cream until smooth and creamy, taking about 1-2 minutes. This mixture serves as the binding agent that gives the casserole its rich custard-like texture. Pour this silky mixture evenly over the beef layer in your baking dish, covering it thoroughly.

Step 6: Add Cheddar Cheese
Generously sprinkle the shredded cheddar cheese over the top of the casserole. This gooey layer will melt into a delightful topping, adding both flavor and texture to the Best Low Carb Taco Casserole. Make sure to distribute the cheese evenly for a beautifully melted finish.

Step 7: Bake to Perfection
Place the baking dish in the preheated oven and bake for 25–30 minutes, or until the cheese is golden and bubbly. Keep an eye on the casserole as it bakes, allowing you to catch that enticing golden color just at the right moment for an appetizing presentation.

Step 8: Rest Before Serving
Once out of the oven, let the casserole rest for about 5 minutes before cutting into it. This resting time allows the layers to set, making it easier to serve and ensuring each slice holds together beautifully. Your Best Low Carb Taco Casserole is now ready to be enjoyed!
