Ingredients Method

Ingredients
  

  • 1.5 pounds ground beef (85% or 90% lean)
  • 1 small yellow onion, diced
  • 1 green bell pepper, diced
  • 2 cloves garlic, minced
  • 1 (10-ounce) can diced tomatoes with green chiles, drained (such as Rotel)
  • 1/2 cup tomato sauce (no sugar added)
  • 8 ounces cream cheese, softened
  • 1/2 cup sour cream
  • 2 cups shredded cheddar or Mexican blend cheese, divided
  • 2 tablespoons olive oil or butter
  • 2 tablespoons taco seasoning (see below or use a low-carb blend)
  • Salt and black pepper, to taste
  • Optional low-carb toppings: sliced jalapeños, diced avocado, chopped cilantro, shredded lettuce, sliced green onions, sour cream

Method
 

  1. Preheat and prep: Heat your oven to 375°F (190°C). Grease a 9x13-inch baking dish.
  2. Sauté the veggies: Warm the olive oil in a large skillet over medium heat. Add the diced onion and bell pepper. Cook for 3–4 minutes until they soften.
  3. Brown the beef: Add the ground beef to the skillet. Break it up with a spatula and cook until no longer pink, about 6–8 minutes. Drain excess fat if needed.
  4. Add seasoning: Stir in the garlic and taco seasoning. Cook for 1 minute until fragrant. Mix in the tomato sauce and drained tomatoes with green chiles. Simmer for 2–3 minutes. Taste and adjust salt and pepper.
  5. Make the creamy layer: In a bowl, beat together cream cheese, sour cream, and 1/2 cup shredded cheese until smooth. If the cream cheese is too firm, microwave it for 15–20 seconds first.
  6. Assemble the casserole: Spread the beef mixture evenly in the baking dish. Dollop the creamy mixture on top and use a spatula to gently spread it. Sprinkle the remaining cheese over everything.
  7. Bake: Bake uncovered for 18–22 minutes, or until the edges are bubbly and the cheese is melted and lightly golden.
  8. Rest and top: Let the casserole rest for 5–10 minutes to set. Add your favorite toppings, such as sliced jalapeños, avocado, cilantro, or shredded lettuce.
  9. Serve: Spoon into bowls and enjoy as is, or pair with cauliflower rice or a simple side salad.
