Ingredients:
For the Casserole Base:
- 1 lb ground beef (preferably 80% lean for added flavor and juiciness)
- 1/2 medium onion, finely chopped
- 2 cloves garlic, minced
- 1 bell pepper, chopped (green or red for added color)
- 1 packet taco seasoning (sugar-free) or homemade mix (see below)
- 1/2 cup salsa (make sure it’s low-carb, with no added sugars)
- 1 cup shredded cheddar cheese (or a Mexican cheese blend)
- 1/2 cup sour cream
Optional Toppings (to customize as desired):
- Chopped tomatoes
- Sliced black olives
- Chopped green onions
- Fresh cilantro
- Sliced avocado or guacamole
- Shredded lettuce for a fresh crunch
Homemade Taco Seasoning Mix (optional):
- 1 tbsp chili powder
- 1 tsp ground cumin
- 1 tsp paprika
- 1/2 tsp onion powder
- 1/2 tsp garlic powder
- 1/4 tsp dried oregano
- Salt and pepper to taste
Instructions:
Step 1: Prepare the Meat Base
- Sauté the Ground Beef and Vegetables: In a large skillet over medium heat, cook the ground beef until browned and crumbly. Use a spatula to break it up into smaller pieces, ensuring even cooking. Adding ground beef with a slightly higher fat content will keep the casserole juicy, but you can drain excess fat if preferred.
- Add Onion, Garlic, and Bell Pepper: Once the beef is browned, add the chopped onion, garlic, and bell pepper to the skillet. Sauté for 3-4 minutes, until the onions become translucent and the bell peppers soften. This step infuses the beef with added flavors and slight sweetness.
- Incorporate Taco Seasoning and Salsa: Sprinkle the taco seasoning over the beef and vegetable mixture, stirring well to coat. If using a homemade blend, you can adjust the spices to your taste. Add salsa, which provides moisture, acidity, and a hint of sweetness that balances the richness of the beef. Let the mixture simmer for 5 minutes, allowing the flavors to meld.
Step 2: Assemble the Casserole
- Layer in a Baking Dish: Preheat your oven to 350°F (175°C). Spoon the seasoned beef mixture evenly into the bottom of a greased 8×8 or 9×9-inch baking dish. This layer acts as the savory foundation of the casserole, rich with taco spices.
- Add Sour Cream Layer: Spread sour cream evenly over the meat layer, giving a creamy, tangy element that contrasts with the spiciness of the beef. This layer also creates a wonderful creaminess as it bakes.
- Top with Cheese: Sprinkle shredded cheddar (or your choice of cheese) on top of the sour cream layer. As it melts, the cheese creates a bubbly, golden layer that adds both flavor and texture to the casserole.
Step 3: Bake and Serve
- Bake: Place the casserole in the preheated oven and bake for about 15–20 minutes, or until the cheese is fully melted and slightly golden on top. Baking briefly allows all the flavors to meld while keeping the textures distinct.
- Garnish and Serve: Remove the casserole from the oven and let it cool for a few minutes. Now, top it with your choice of garnishes. Add fresh chopped tomatoes and green onions for a burst of color, sliced avocado for creaminess, or a sprinkle of cilantro for a fresh, aromatic touch. Shredded lettuce on the side adds crunch and pairs well with each flavorful bite.
Tips for Serving and Storing
- Serving Suggestions: Serve the casserole warm with a side of guacamole or sour cream. For an extra crunch, pair it with keto-friendly tortilla chips or spoon it into romaine lettuce leaves as a low-carb taco.
- Storing Leftovers: Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or oven until warmed through, and add fresh toppings as desired.
