How to Make Cheesy Chicken Casserole
- Preheat the Oven: Heat your oven to 375°F. This will ensure even cooking for that bubbling, golden top we all love.
- Cook the Shells: In a large pot, bring salted water to a boil and cook 3 cups medium shells according to package directions until al dente. This prevents them from overcooking in the oven.
- Sauté Vegetables: In a skillet, melt 3 tablespoons butter over medium heat. Add the finely diced onion and diced red bell pepper, stirring until they are tender, about 5 minutes. Stir in 1 teaspoon chili powder and ½ teaspoon seasoned salt for added flavor.
- Mix the Sauce Together: In a large bowl, combine 1 (10.5 ounce) can condensed cream of chicken soup, the sautéed onion and pepper mixture, 1⅓ cups milk, and 2 cups shredded sharp cheddar cheese along with ⅓ cup shredded parmesan cheese. Mix well until everything is incorporated.
- Add Chicken and Pasta: Fold in the 3 cups cooked chopped chicken and 4 ounces canned mild green chiles to the cheese mixture, then stir in the cooked pasta until everything is evenly coated.
- Transfer to Baking Dish: Spread the mixture into a 9×13 casserole dish, smoothing it out evenly. Top with the remaining 1 cup of shredded sharp cheddar cheese.
- Bake: Place the dish in the preheated oven and bake for 30 to 35 minutes, or until it’s hot and bubbly, and the cheese is nice and golden.
Storing & Reheating
To store your cheesy chicken casserole, let it cool to room temperature, then cover it tightly with plastic wrap or aluminum foil. It will keep in the refrigerator for up to 3 days. If you want to freeze it, I recommend portioning it into freezer-safe containers, which can last up to 3 months. To reheat, simply bake it in a preheated oven at 350°F for about 25 minutes, or until warmed through. You may notice slight changes in texture, but refreshing it with a drizzle of milk before reheating can bring back some creaminess.
Chef’s Helpful Tips
- Ensure your chicken is chopped into small, even pieces for uniform heating.
- Use freshly grated cheese instead of pre-shredded for better melting and creaminess.
- If the casserole appears too thick, feel free to add a splash more milk for a lovely, creamy consistency.
- Consider adding a layer of breadcrumbs on top before baking for an added crunch.
- This casserole can easily be doubled for larger gatherings or meal prep.
There’s nothing quite like a hearty, cheesy chicken casserole that brings everyone to the table. This dish bursts with flavor and comfort, providing a satisfying meal that’s sure to become a favorite in your household. I encourage you to try different variations—perhaps adding your favorite vegetables or using a different cheese—to make it truly your own. The flexibility is what makes this recipe even more special!
