Complete Your Meal
Transform this hearty casserole into a complete feast by serving it alongside a crisp Caesar salad dressed with homemade garlic croutons. Warm garlic bread makes the perfect companion for soaking up every last drop of the flavorful sauce, while roasted vegetables add color and nutrition to round out the meal.
Customize Your Creation
Adapt this versatile dish by incorporating mushrooms and bell peppers for added vegetables and texture. Switch up the cheese blend by using pepper jack for extra heat, or add a layer of black beans for a heartier Southwestern twist. For a lighter version, substitute ground turkey and Greek yogurt without sacrificing flavor.
Storage Success
Keep your casserole fresh by storing it covered in the refrigerator for up to four days. Reheat individual portions in the microwave, or warm larger amounts in a 350°F oven until heated through. For busy weeks ahead, assemble the entire dish, wrap tightly, and freeze for up to three months.
