What to serve with fajita casserole?

Chicken fajita casserole pairs beautifully with a variety of sides depending on your preferences. For a fresh and light option, try a green salad with lime vinaigrette or sliced avocado. Want something hearty? Go for cilantro-lime rice, black beans, or warm corn tortillas. If you're watching your carbs, serve it with cauliflower rice or roasted vegetables. A creamy corn dish, such as elote or Mexican street corn, also complements the bold flavors of the casserole.

What ingredients go in chicken casserole?

Chicken casseroles come in many forms, but a fajita-style version includes seasoned chicken, sliced bell peppers, onions, shredded cheese, and sometimes rice or tortillas. Other typical casserole ingredients can include sour cream, cream cheese, beans, or tomatoes for extra richness and depth. The key is layering textures and flavors in one dish.

Is fajitas healthy or unhealthy?

Fajitas, especially in casserole form, can absolutely be healthy. The dish is naturally rich in lean protein and vegetables. What makes fajitas “unhealthy” is often the excess cheese, fatty cuts of meat, or sides like flour tortillas and chips. When you control the ingredients—using skinless chicken, fresh produce, and moderate cheese—it becomes a balanced, nutritious meal that fits many diets, including low-carb and keto.

What to marinate chicken in for chicken fajitas?

The best fajita marinade includes olive oil, lime juice, chili powder, cumin, garlic powder, paprika, salt, and pepper. You can also add a splash of soy sauce or Worcestershire for extra depth. Marinate the chicken for at least 30 minutes, or up to 12 hours, for maximum flavor. This not only adds taste but also helps keep the chicken juicy during baking.

Can I use leftover chicken in a fajita casserole?

Yes, using leftover chicken is a great time-saver. Simply slice or shred the cooked chicken and mix it with the sautéed vegetables and seasoning. Since it’s already cooked, reduce the baking time to about 20–25 minutes to avoid drying it out.

How long can you store fajita casserole in the fridge?

Once baked, chicken fajita casserole can be stored in an airtight container in the refrigerator for 3 to 4 days. For meal prep, divide leftovers into single-serving containers for quick lunches. Reheat in the microwave or oven until hot throughout. You can also freeze portions for up to 2 months.
