Tips & Substitutions

For a spicier kick, consider using spicy jalapenos or adding a dash of hot sauce to the sauce mixture. If you prefer a healthier option, substitute the Doritos or Fritos with baked tortilla chips. You can also use reduced-fat Monterey Jack cheese to lighten the dish. This casserole can be customized with additional vegetables like bell peppers or corn for added flavor and nutrition.

Serving Suggestions

Serve the casserole with a side of Mexican Avocado Dip for a refreshing contrast and a burst of flavor. A simple green salad or some sautéed veggies can round out the meal nicely. This dish pairs well with a side of Mexican Creamed Corn for a comforting, hearty dinner. For an extra kick, serve with additional jalapenos on the side.
