1. Preheat the Oven:

  5. Top with the remaining 6 bread slices, margarine-side up.

4. Bake the Casserole:

  1. Cover the baking dish with aluminum foil and bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly.

Cook Notes and Variations:

  • Bacon Substitution: If you prefer, you can use cooked and crumbled turkey bacon or vegetarian bacon bits as a substitute for real bacon bits.
  • Cheese Options: Feel free to experiment with different types of cheese to suit your taste preferences. Sharp cheddar, Swiss, or pepper jack would all work well in this recipe.
  • Bread Choices: While traditional white or wheat bread works great in this casserole, you can also use sourdough, Italian, or even Texas toast for added flavor.

Keto Versions and Low-Carb Versions:

Keto Version:

  • Bread Substitute: Replace the bread slices with low-carb alternatives such as almond flour bread, cloud bread, or keto-friendly tortillas.
  • Condiment Adjustment: Opt for sugar-free versions of ketchup and mustard to reduce carb content.

Low-Carb Version:

  • Breadless Casserole: Omit the bread entirely and enjoy the cheesy beef mixture on its own or serve over a bed of lettuce for a low-carb option.
  • Vegetable Addition: Add chopped vegetables such as bell peppers, mushrooms, or spinach to boost the nutrient content and add extra flavor.
