Transfer the mixture to a greased 9×13-inch baking dish. Sprinkle the remaining cheddar cheese on top.
Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden brown.
Let it cool for a few minutes before serving.
Variations & Tips
For a lighter version, you can substitute ground turkey or chicken for the beef. If you’re looking to add more veggies, consider tossing in some chopped bell peppers or zucchini. For a bit of spice, add a pinch of red pepper flakes or a dash of hot sauce to the mixture. If you’re short on time, you can prepare the casserole the night before and simply bake it when you’re ready to eat.
