How to Make KETO Mexican Casserole
Step 1: Prepare the Beef Mixture
In a large skillet over medium heat, cook the chopped onion until translucent. Add minced garlic and ground beef, cooking until browned. Once the beef is fully cooked, drain any excess fat, and stir in diced tomatoes, chili powder, cumin, paprika, salt, and pepper. Let simmer for about 5 minutes to allow the flavors to develop.
Step 2: Assemble the Casserole
Preheat your oven to 350°F (175°C). In a mixing bowl, combine sour cream and half of the shredded cheese. Start layering the casserole in a dish: place a layer of low-carb tortillas at the bottom, followed by half of the beef mixture, then half of the sour cream mixture. Repeat the layers, finishing with a final layer of tortillas on top.
Step 3: Top and Bake
Sprinkle the remaining cheese generously over the casserole. If using, add diced bell peppers on top for color and crunch. Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.
Tips for the Best Results
- Browning: Ensure the beef is well browned; this step enhances the flavor.
- Layering: For even cooking, keep the layers consistent — avoid piling too much on one side.
- Cheese: Using a mix of cheeses can elevate the flavor profile; consider adding Monterey Jack or pepper jack for a kick.
- Resting Time: Allow the casserole to sit for about 5-10 minutes after baking; this helps set the layers.
- Serving: Garnish with fresh cilantro or jalapeños for a pop of flavor.
Variations and Substitutions
Feel free to experiment with the vegetables you include in this casserole. Zucchini or spinach can be great low-carb options to add in, enhancing nutrition without adding carbs. For a vegetarian alternative, replace the ground beef with black beans or a meat substitute.
