Variations & Tips
If you're looking to switch things up, try adding a can of corn or some sliced mushrooms to the mixture for extra veggies. You could also use ground turkey or chicken instead of beef for a lighter version. For a bit of a kick, mix in some chopped jalapeños or a dash of hot sauce. If you prefer a creamier casserole, add a can of cream of mushroom soup to the mix before baking.
