Ingredients to make Southwestern Chicken Casserole
- Rice: We start off with some good ol’ long grain white rice! It’s my favorite for this casserole.
- Liquids for Cooking: You’ll need some chicken stock and a splash of fresh lime juice. If you want to keep things from getting too salty, use low-sodium stock – you can always add more salt, but you sure can’t take it out!
- Veggies: Dice up some yellow onion and green bell pepper, and toss in some minced jalapeño for a kick. If jalapeños aren’t your style or you want less heat, a mild green chili works great too.
- Garlic and Spices: Grab a few cloves of garlic, and for the spices, we’re talking chili powder, dried oregano, and ground cumin. These will give your casserole that warm, comforting flavor.
- Fire-Roasted Diced Tomatoes: For that nice, smoky flavor.
- Tomato Paste: Just a bit of tomato paste will help thicken things up and enrich the sauce.
- Add-Ins: Sweet corn and black beans bulk this Southwestern chicken casserole recipe up. I use canned for convenience, but hey, if you’ve got some cooked beans sitting in the fridge, toss those in!
- Chicken: Here’s where it gets even easier. I like to use rotisserie chicken because it’s simple to shred and toss into the mix. Plus, it’s flavorful and moist!
- Fresh Cilantro: For a nice herby pop.
- Crushed Tortilla Chips: They give that delightful crunch on top. You can go with plain or a flavored variety.
- Cheese: A good shred of fiesta or Mexican blend cheese melts beautifully and ties all the flavors together.
How to make Southwestern Chicken Casserole
Step 1: bake the rice
- Place rice, salt, stock, and lime juice in a baking dish.
- Cover with foil and bake for 25 minutes.
Step 2: cook the casserole mixture
- Add oil, onion, bell pepper, and jalapeno to a large nonstick skillet. Season with the remaining salt.
- Cook over medium-high heat until vegetables are translucent and softened. Add garlic and spices and continue cooking for a minute.
- Stir in diced tomatoes and tomato paste. Let it cook until just a little liquid remains.
- Remove from heat. Fold in corn, black beans, chicken, cilantro, and tortilla chips.
Step 3: add the mixture to the baking dish, top it with cheese, and bake
- Remove the rice from the oven once it’s par-cooked, and pull back the foil.
- Add the chicken mixture to the rice. Recover with foil and bake.
- Take out the casserole from the oven once the rice is fully cooked, and remove the foil. Switch the oven to broil, and top the casserole with the remaining tortilla chips and cheese.
- Place the casserole under the broiler and broil until the cheese melts. Let it sit for a few minutes, garnish with the remaining cilantro, and serve.
Tips for making the best southwest chicken and rice casserole
- Layer It Evenly: When you’re scooping that spicy, savory mix onto your rice, take a moment to smooth it out. An even layer means every bite’s got a bit of everything, which is just how you want it.
- Be Patient, Darlin’: I know boo, it’s tempting to dig right in when that casserole comes bubbling out of the oven (I’ve done it myself a few times), but give it a few minutes to cool down. This lets everything settle nicely, so when you scoop it out, it doesn’t just fall apart.
- Eye on the Broil: When you pop that casserole under the broiler, don’t wander off! Those tortilla chips and cheese can go from just right to overdone quicker than you can say “bless ya heart”.
- Crunchier Top: If you love a bit more crunch and texture on top of your southwest chicken casserole, don’t be shy with the tortilla chips. Add an extra handful just before it goes under the broiler!
Popular substitutions & additions
- Swap the Protein: If you’re not feelin’ chicken tonight, pulled pork or ground turkey can step right in and mix things up. They soak up the spices just as well and make the casserole just as filling AND tasty.
- Go Green with Veggies: Mix in some spinach or kale for an extra pop of color and nutrients! Just stir it in when you add the beans and corn so it wilts nicely but doesn’t get too soggy.
- Cheese Variety: Try swapping out the fiesta blend cheese for some sharp cheddar or smoked gouda for a different kind of cheesy goodness.
- Freshen It Up: A dollop of sour cream or a few slices of avocado on the side not only look pretty but they’ll cool down the spices just a touch and add a creamy texture that complements the hearty ingredients.
- Zest It: If you’re a fan of a little extra zing, squeeze a bit more lime over your southwest chicken and rice casserole right before you serve it up. Fresh cilantro sprinkled on top doesn’t hurt either!
What to serve with this southwestern chicken casserole recipe
- This casserole is pretty filling and hearty by itself, but if you want to double the heartiness, Roasted Sweet Potatoes or a skillet of Fried Corn make fantastic sides.
- Toss up a refreshing Vinegar Coleslaw or a simple Shrimp Caesar Salad. These cool, crisp salads are great to balance the warm spices of the casserole.
- Since this casserole’s got those Mexican vibes, why not lean into it with some dips and sauces? Whip up some Guacamole, Salsa Verde, or a Chimichurri Sauce. They’re perfect for pre-dinner munching or even spooned right on top of each casserole serving.
- For a real down-home feel, a side of Pinto Beans or Red Beans could be just da thing. A tasty nod to the casserole’s Southwestern roots!
How to store & reheat Southwestern Chicken Casserole
After your casserole has cooled down, cover it tightly with foil or plastic wrap (or transfer it to an airtight container) and place it in the fridge. This will keep everything nice and moist!
To bring that Southwestern casserole back to life, you can warm it in the oven at 350°F until it’s heated through, which usually takes about 20 minutes. If you’re just reheating an individual portion, a couple of minutes in the microwave will do the trick. E
How long will Southwestern Chicken Casserole last in the fridge?
Safely tucked away in the fridge, your casserole will stay fresh and tasty for up to 3 to 4 days. Just make sure it’s cooled completely before you pack it away to keep things safe and sound.
Can I freeze southwest chicken casserole?
Of course, boo! Just wrap it well in foil or transfer to a freezer-safe container, and it’ll keep for up to 2 months. Then, thaw it in the fridge overnight and reheat it using the instructions above to get that “just-baked” taste.
Frequently asked questions
Can I make this casserole ahead of time?
Absolutely! You can assemble the entire casserole a day in advance and store it in the fridge, covered. When you’re ready to eat, just pop it in the oven and add a few extra minutes to the baking time since you’re starting from cold.
What can I use instead of tortilla chips for the topping?
Crushed cornflakes or even a sprinkle of breadcrumb mixed with a bit of melted butter can create a delicious, crunchy topping!
What can I do if the casserole comes out too dry?
Make sure you cover it tightly with foil while it bakes to lock in moisture. If it still seems dry, you can stir in a little extra chicken stock before adding your cheese and chips. Easy fix!
It’s about time to roll up those sleeves and dive into making this Southwestern Chicken Casserole! Packed with juicy chicken, a hint of lime, and just the right amount of spice, it’s a recipe that’s sure to liven up any weeknight.
