How to Make Chicken Fajita Casserole Recipe
Step 1: Cook the Chicken
Start by heating olive oil in a large skillet over medium heat. Add the thin strips of chicken breast and cook them until they’re lightly browned and cooked through, about 5 to 6 minutes. This step seals in the juiciness and develops those great flavors that form the base of the casserole.
Step 2: Sauté the Vegetables
In the same skillet, toss in your sliced red, green, and yellow bell peppers along with the red onion. Let them sauté for 4 to 5 minutes or until they soften slightly but still have a bit of crunch. This keeps the vegetables vibrant and gives the casserole a wonderful texture contrast.
Step 3: Season the Mixture
Add the cooked chicken back to the skillet and sprinkle over the chili powder, cumin, smoked paprika, garlic powder, salt, and black pepper. Stir everything to coat the chicken and veggies evenly, allowing those bold fajita spices to meld beautifully with the ingredients.
Step 4: Prepare the Creamy Base
In a large mixing bowl, combine the sour cream and softened cream cheese until you have a smooth, creamy mixture. This step is key to that luscious, cheesy sauce that brings the whole casserole together with rich, tangy goodness.
Step 5: Combine & Bake
Stir the seasoned chicken and vegetable mixture into the creamy base, then transfer this delicious blend into a greased 9×13-inch baking dish. Top everything generously with shredded cheddar and Monterey Jack cheeses. Slide the casserole into your preheated oven at 375°F and bake for 20 to 25 minutes, until the cheese is melted, bubbly, and turning a gorgeous golden brown.
How to Serve Chicken Fajita Casserole Recipe
Garnishes
For the ultimate finishing touch, sprinkle the casserole with freshly chopped cilantro and offer lime wedges on the side. The cilantro adds a burst of green freshness, and a squeeze of lime juice cuts through the creamy richness, brightening every mouthful with a subtle tang.
Side Dishes
This casserole pairs beautifully with simple sides like a crisp green salad, Mexican rice, or even warm tortillas to scoop it all up. You can also serve it alongside black beans or corn for a hearty, balanced meal that still feels light and fresh.
Creative Ways to Present
Try spooning the Chicken Fajita Casserole onto a bed of fluffy rice or stuffing it into baked potatoes for a fun twist. You can also turn it into a taco night centerpiece by serving portions alongside your favorite taco toppings like guacamole, salsa, and sour cream. It’s an incredibly versatile dish that shines in many different presentations.
