- 1 (10.5-ounce) can cream of chicken soup: Brings a creamy richness that melds the ingredients beautifully.
- 1 cup sour cream: Adds tang and moisture, balancing the spices perfectly.
- 1 cup frozen diced onion and bell pepper blend: The classic fajita veggies for sweetness and crunch.
- 1 (10-ounce) can diced tomatoes with chilies (undrained): Adds juiciness and a subtle kick.
- 1 1/2 cups chicken broth: Keeps everything moist and infuses extra savory depth.
- 1 (1.12-ounce) packet fajita seasoning: The essential spice mix that delivers authentic fajita flavor.
- 1 (8-ounce) package shredded Mexican blend cheese: Seasonal melty cheese to top and melt over the casserole.
How to Make Cheesy Chicken Fajita Casserole Recipe
Step 1: Prepare and Preheat
Start by preheating your oven to 350°F. Lightly spray a 9×13-inch baking dish with nonstick cooking spray to ensure your casserole slides out easily after baking and to prevent any sticky spots. This simple first step makes cleaning afterward a breeze.
Step 2: Combine Your Ingredients
In a large mixing bowl, toss together the shredded chicken, uncooked instant rice, cream of chicken soup, sour cream, frozen diced onions and bell peppers, diced tomatoes with chilies (leave the juice in), chicken broth, and fajita seasoning. This combination packs a punch of flavors and textures that promise a delicious result. Stir in half of the shredded cheese right here so it melds into the mix as it cooks.
Step 3: Bake the Casserole
Pour your flavorful mixture evenly into the prepared baking dish. Cover it tightly with foil to trap steam and moisture, which helps the rice cook perfectly tender and the flavors marry together. Bake for 35 to 45 minutes — you’ll know it’s done when the rice is soft and all the ingredients have set into a creamy, cohesive casserole.
Step 4: Cheese It Up and Finish Baking
Once the rice is tender and the casserole is bubbling, remove the foil and sprinkle the remaining shredded Mexican cheese over the top. Return the dish to the oven just long enough for the cheese to melt into a gooey, golden blanket—usually about 5 minutes. This finishing touch is what takes the casserole from wonderful to unforgettable.
How to Serve Cheesy Chicken Fajita Casserole Recipe
Garnishes
Add a fresh and colorful boost by garnishing with chopped cilantro, sliced green onions, or even a dollop of sour cream. A squeeze of lime over the top brightens the rich cheesy flavors, making every bite pop with freshness.
Side Dishes
While this casserole is satisfying on its own, pairing it with light sides such as a crisp garden salad, crunchy tortilla chips, or a simple guacamole enhances the meal experience by adding texture and complementary flavors.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins or small cast iron skillets to create personal servings with crispy edges. You can also scoop it into warm tortillas for a layered fajita casserole burrito, perfect for casual get-togethers.
Make Ahead and Storage
Storing Leftovers
After enjoying your delicious Cheesy Chicken Fajita Casserole, store any leftovers in an airtight container in the refrigerator. It will keep well for up to 3 days, allowing you a quick reheat option for lunches or dinners during the week.
Freezing
This casserole freezes beautifully. Prepare according to the recipe, but before baking, cover tightly with aluminum foil and freeze. When ready to enjoy, bake it from frozen at 350°F for about an hour and a half, removing the foil and adding cheese halfway through baking.
Reheating
Reheat individual portions in the microwave until warmed through or place the leftover casserole in a 350°F oven until heated evenly and bubbly. Adding a sprinkle of fresh cheese on top before reheating will bring back that fresh-from-the-oven melty goodness.
FAQs
Can I use fresh vegetables instead of frozen?
Absolutely! Fresh onions and bell peppers diced finely will add great flavor and texture; just sauté them lightly before adding to the mix to soften them slightly.
What if I don’t have instant rice?
If you only have regular rice, cook it separately before mixing in, as it will require different cooking times and liquid ratios that could affect the casserole’s texture.
Is there a way to make this casserole spicier?
Yes! Add extra diced jalapeños, a dash of cayenne pepper, or a spicier variety of diced tomatoes with chilies to turn up the heat to your liking.
Can this casserole be made vegetarian?
For a vegetarian version, substitute the chicken with sautéed mushrooms or plant-based chicken alternatives, and use vegetable broth instead of chicken broth for full flavor without meat.
Can I double this recipe for a larger crowd?
Definitely! Just double the ingredients and bake in a larger casserole dish or two separate dishes, adjusting the baking time as needed until the rice is tender and cheese melted.
