Ingredients You’ll Need

All the ingredients for this Creamy Chicken and Veggie Casserole Recipe come together to create a delicious harmony of flavors and textures. I always recommend using fresh or thawed veggies to keep it vibrant, and quality chicken to make it hearty.

• Chicken breast: I prefer fresh, boneless chicken breasts chopped into bite-sized pieces for even cooking.
• Yellow onion: Adds a natural sweetness and depth of flavor after sautéing.
• Red and green bell peppers: These bring a lovely crunch and vibrant color to the dish.
• Frozen spinach: Convenient and nutrient-packed; be sure to squeeze out excess water before adding.
• Cremini mushrooms: They add earthiness and a meaty texture, balancing the creaminess nicely.
• Condensed cream of mushroom soup (98% fat free): This is the base of the creamy sauce, making it rich without being heavy.
• Non-fat sour cream: Gives the casserole that silky, tangy richness that keeps it from feeling too heavy.
• Unsalted butter: For sautéing and adding subtle richness.
• Minced garlic: Brings aromatic warmth.
• Paprika: A touch for smoky depth and subtle spice.
• Salt and pepper: Essential for seasoning to taste.

Variations

I love how flexible this Creamy Chicken and Veggie Casserole Recipe is—it’s like a blank canvas for creativity. Over time, I’ve tried swapping veggies and protein sources, which always keeps the dish fresh and exciting. You should definitely customize it to your taste or what you have on hand!

• Use rotisserie chicken: When I’m short on time, shredded rotisserie chicken works perfectly and adds a little smoky flavor.
• Swap in different veggies: Broccoli, zucchini, or carrots blend right in and keep things colorful.
• Make it vegetarian: Replace chicken with chickpeas or tofu for a delicious plant-based casserole.
• Cheesy twist: Sprinkle shredded cheddar or mozzarella on top before baking for a melty crust that my family adores.

How to Make Creamy Chicken and Veggie Casserole Recipe

Step 1: Prep Your Ingredients with Care

First things first, preheat your oven to 375°F to get it ready for baking. While the oven warms up, chop the yellow onion, slice your bell peppers into strips, and slice the cremini mushrooms. Pop the frozen spinach (still sealed) into a bowl of hot water to thaw—this speeds up the process while you prep everything else. Once thawed, squeeze out as much water as you can to avoid a soggy casserole later.

Step 2: Sauté Those Veggies Until They’re Just Right

Heat a large pan on medium and melt your butter until it’s bubbling. Toss in the garlic first for about 30 seconds, just until fragrant—watch closely because garlic burns fast! Then add the onions, bell peppers, and mushrooms. Sauté gently for 5 to 10 minutes until the onions turn translucent and peppers start softening. Finally, mix in the thawed and drained spinach. This blend of tender, flavorful veggies makes the dish so satisfying.

Step 3: Prep and Combine Your Chicken

While your veggies are working their magic, cut the chicken breast into bite-sized pieces. If you prefer, you can slice the chicken into bigger cutlets and lay those on top of the casserole later—but I’ve always found that mixing bite-sized chicken through ensures every bite has protein goodness. Once your veggies are cooked, stir in the cream of mushroom soup, sour cream, paprika, salt, and pepper until the sauce is smooth and creamy.

Step 4: Bake It to Perfection

Spray a baking dish lightly with non-stick spray, then pour your creamy chicken and veggie mixture right in. Pop it into your preheated oven and bake for about 20 minutes. If you used chicken cutlets on top instead of mixed in, make sure to check they’re fully cooked through before serving. The oven time gives everything a chance to meld together and develop that irresistible casserole texture.

Step 5: Serve and Enjoy!

Serve this casserole all on its own or ladled over your favorite base – noodles, zucchini noodles, rice, or even cauliflower rice work beautifully here. I love the creamy sauce soaking into noodles, which makes this dish feel indulgent yet wholesome. Just grab a fork and enjoy that cozy, flavorful bite!

Garnishes

I love topping this casserole with freshly chopped parsley or a sprinkle of chopped chives to add a pop of color and freshness. Sometimes, I add a little shredded cheddar or parmesan right before serving if I want a cheesy finish. These simple garnishes uplift the flavor and presentation instantly.

Side Dishes

For sides, my go-to is a crisp green salad with a tangy vinaigrette—something light to balance the creaminess. Roasted garlic bread is another favorite; it’s perfect for scooping up the saucy bits. When I want to keep it low-carb, a side of steamed broccoli or cauliflower rice pairs wonderfully.

Creative Ways to Present

For special occasions, I like to serve the casserole in individual ramekins, topped with a sprinkle of toasted breadcrumbs and a little cheese broiled until golden. It’s a fun, personalized touch that impresses guests and makes leftovers feel extra special. You can also add a drizzle of hot sauce or a dollop of guacamole for an unexpected twist!

Make Ahead and Storage

Storing Leftovers

I usually store leftovers in an airtight container in the fridge for up to 3 days. I like to give it a gentle stir before reheating to redistribute the sauce since it can thicken in the fridge. It keeps its flavor and texture much better than many casseroles I’ve tried!

Freezing

This casserole freezes beautifully. I portion it out into freezer-safe containers before baking, then thaw overnight in the fridge when ready to use. When I’m pressed for time, I bake frozen portions straight from the freezer, just adding extra baking time and covering with foil to prevent drying.

Reheating

To reheat, I cover the casserole with foil and warm it in a 350°F oven until heated through—usually about 15-20 minutes. This method keeps it creamy and prevents drying out like a microwave often does. You can sprinkle a little extra sour cream or broth if it seems a bit thick.
