Ingredients You’ll Need
- 3 cups medium shells uncooked: These pasta shapes hold onto the creamy sauce perfectly, ensuring every bite is a delight. You could substitute with penne or rotini if needed.
- 3 tablespoons butter: Adds richness and depth to the dish; feel free to use olive oil for a lighter option.
- 1 onion finely diced: The foundation of flavor; sautéing releases its sweetness. Yellow or white onions work best!
- ⅓ cup diced red bell pepper: For a pop of color and crunch; green bell pepper or even a bit of jalapeño can be fun alternatives if you prefer some heat.
- 1 teaspoon chili powder: Gives the casserole a flavorful kick. Use smoked paprika for a different depth of flavor.
- ½ teaspoon seasoned salt: Enhances all the other flavors; consider using garlic powder or onion powder as substitutes.
- 1 (10.5 ounce) can condensed cream of chicken soup: This creates a creamy base. If preferred, you can make a homemade white sauce instead.
- 1⅓ cups milk: Thin out the soup and keep everything creamy; almond milk or oat milk can be used for dairy-free options.
- 3 cups shredded sharp cheddar cheese: You need that ooey-gooey cheesy goodness. Feel free to mix in some mozzarella for stretchiness or pepper jack for a spicy twist.
- ⅓ cup shredded parmesan cheese: Adds a nutty depth to the flavor profile; you could use nutritional yeast for a dairy-free version.
- 3 cups cooked chopped chicken: Utilizing leftover chicken or a rotisserie saves time here; shredded turkey works just as well.
- 4 ounces canned mild green chiles: Offers a mild heat and flavor; you can leave them out if you want a milder dish or use hotter chiles for an extra kick.
How to Make Cheesy Chicken Casserole
- Preheat the Oven: Start by heating your oven to 375°F; this ensures it’s hot and ready for that delicious casserole.
- Cook the Pasta: In a large pot, bring water to a boil and cook the medium shells until al dente according to package directions. Drain and set aside, allowing them to cool slightly.
- Sauté Vegetables: In a skillet, melt the butter over medium heat. Add the finely diced onion and red bell pepper, cooking until they’re tender and fragrant, about 5 minutes. Stir in the chili powder and seasoned salt, allowing the spices to bloom.
- Combine Ingredients: In a large bowl, mix the condensed cream of chicken soup with the onion mixture, then whisk in the milk until smooth. Add 2 cups of the shredded sharp cheddar cheese and the grated Parmesan cheese, mixing until uniformly combined. Stir in the cooked chicken, green chiles, and the cooked pasta, ensuring everything is well coated.
- Assemble the Casserole: Spread the mixture into a 9×13 casserole dish evenly. Top with the remaining shredded cheddar cheese to create that irresistible cheesy crust.
- Bake: Place the casserole in the preheated oven and bake for 30 to 35 minutes, or until the edges are bubbling and the top is a lovely golden brown.
Storing & Reheating
To keep your Cheesy Chicken Casserole fresh, store any leftovers in an airtight container in the refrigerator for up to 5 days. If you’d like to freeze it for later, cozy up the casserole in a covered dish and place it in the freezer for up to 3 months. When it’s time to enjoy it again, thaw overnight in the refrigerator and reheat in the oven at 350°F for about 20 minutes, or until it’s heated through. Just note that the texture may change slightly, but a sprinkle of fresh cheese on top before baking will do wonders to refresh it.
Chef’s Helpful Tips
- Watch the edges of the casserole while baking; if they’re browning too quickly, cover loosely with foil.
- To ensure every ingredient melts and blends perfectly, let your ingredients sit at room temperature for about 20 minutes prior to assembling.
- Experiment with different proteins: shredded beef or even veggies make a delightful twist!
- If you like a bit of crunch, adding crushed tortilla chips or breadcrumbs on top might be the perfect topping before the last few minutes of baking.
- Make ahead by preparing the casserole up to the baking step, then cover and refrigerate overnight.
Even if you veer away from the typical substitutions, don’t hesitate to customize ingredients based on what’s available or your family’s preferences.
