How to Make Keto Taco Casserole (Quick Overview)
This is a brief overview. See the recipe card below for exact measurements and full instructions.
Preheat the oven to 350°F.
Sauté ground beef, onion, garlic, and bell pepper over medium heat until the beef is browned and the vegetables begin to soften.
Drain excess fat, then stir in taco seasoning. Spread the beef mixture into a casserole dish (a 9″ x 9″ works well).
In a small bowl, combine salsa, sour cream, and 1/2 cup of shredded cheese. In another bowl, whisk the eggs and then blend them into the salsa mixture until smooth.
Pour the egg-salsa-cheese mixture evenly over the beef layer. Bake until set, then top with the remaining cheese and return to the oven until melted and bubbly.
Let rest briefly, cut into portions, and serve. Tip: pair with lettuce, sliced avocado, or your preferred low-carb sides.
