Ingredients

Scale

Proteins:

  • 2 cups chicken, shredded
  • 1 can black beans, drained and rinsed

Vegetables:

  • 1 cup bell peppers, sliced
  • 1 cup onion, sliced
  • 1 cup corn, frozen

Seasonings and Liquids:

  • 2 cups shredded cheese
  • 1 cup salsa
  • 1 tablespoon fajita seasoning
  • 1 tablespoon olive oil

Instructions

  1. Warm your oven to 350°F, creating the perfect cooking environment for this zesty casserole.
  2. Pour 1 tablespoon olive oil into a skillet, heating over medium temperature until shimmering.
  3. Toss 1 cup sliced onions and 1 cup bell peppers into the skillet, sautéing for 4-5 minutes until they soften and release their aromatic flavors.
  4. Grab a large mixing bowl and combine 2 cups shredded chicken, 1 can drained black beans, 1 cup frozen corn, 1 cup salsa, your sautéed vegetables, and 1 tablespoon fajita seasoning.
  5. Stir the mixture thoroughly, ensuring each ingredient is well distributed throughout the casserole base.
  6. Transfer the entire mixture into a baking dish, spreading it evenly to create a consistent layer.
  7. Sprinkle 2 cups shredded cheese across the top, covering the entire surface for maximum cheesy goodness.
  8. Slide the dish into the preheated 350°F oven, baking for 25-30 minutes until cheese melts completely and edges start to bubble.
  9. Remove from oven and allow the casserole to rest for 3-4 minutes, letting flavors settle before serving.

Notes

  • Swap chicken for black beans or tofu to make this a vegetarian-friendly dish perfect for meatless nights.
  • Use low-fat cheese and add extra vegetables to boost nutrition and keep the casserole lighter.
  • For extra flavor, sprinkle fresh cilantro or green onions on top right before serving to add brightness.
  • Prepare the mixture ahead of time and refrigerate, then bake when ready for an easy make-ahead meal that saves time on busy evenings.
