How to Make Chicken Fajitas Casserole (easy and cheesy!)
Let’s Make It Together:
- Preheat your oven to 350°F.
- In a large skillet over medium heat, drizzle the olive oil and sauté the chicken pieces until they are cooked through. Remove the chicken from the skillet and set aside.
- In the same skillet, add the sliced onions and bell peppers. Sauté until they reach your desired level of tenderness.
- Return the cooked chicken to the skillet, then stir in the fajita seasoning, sour cream, and softened cream cheese. Mix everything well, creating a creamy, fragrant mixture.
- Transfer the chicken and vegetable mixture to a baking dish, sprinkle the top generously with grated cheddar cheese, and bake in the preheated oven for 10 to 15 minutes or until the cheese is golden and bubbling.
Delicious Variations to Try
- Spicy Kick: Add sliced jalapeños or a dash of hot sauce to the mix if you like a little extra heat!
- Veggies Galore: Incorporate other veggies like zucchini or mushrooms for added nutrition and flavor.
- Taco Twist: Sprinkle crushed tortilla chips on top before baking for a crunchy Tex-Mex flair!
- Swap the Cheese: Try a blend of pepper jack and gouda for a smoky, zesty flavor.
Chef Emma’s Helpful Tips
- Make-Ahead Magic: Prepare the chicken and veggies in advance and store them in the fridge, then just mix and bake when you’re ready to eat!
- Ingredient Swaps: If you don’t have cream cheese on hand, Greek yogurt can add creaminess and a bit of tanginess.
- Storage Suggestions: Leftovers can be stored in the fridge for up to 3 days. Reheat in the oven for best results instead of a microwave to keep the cheese nice and melty.
- Perfectly Sliced Peppers: To make slicing easier, cut the bell peppers in half lengthwise, remove the seeds, and then slice into strips.
