Ingredients You’ll Need

The ingredients for this creamy chicken and veggie casserole recipe come together beautifully — fresh chicken, a vibrant medley of vegetables, and a creamy sauce base that’s comforting without weighing you down. When shopping, fresh veggies with good color and quality chicken will really elevate this dish.

• Chicken breast: Opt for fresh, boneless, skinless breasts and cut them into bite-sized pieces for even cooking.
• Yellow onion: Adds a sweet, aromatic base flavor when sautéed.
• Red and green bell peppers: Choose firm, shiny peppers for that crisp, sweet crunch after cooking.
• Frozen spinach: Convenient and packed with nutrients; just be sure to drain it well.
• Cremini mushrooms: These add a nice earthy depth and meaty texture.
• Condensed cream of mushroom soup: The secret to creamy sauce without heavy cream — I love the flavor and ease it brings.
• Non-fat sour cream: Adds tang and creaminess with fewer calories.
• Unsalted butter: For sautéing vegetables to bring out their natural sweetness.
• Minced garlic: A small punch of garlic brightens up the whole dish.
• Paprika, salt, and pepper: Simple spices that balance flavor and add warmth.

Variations

One thing I love about this creamy chicken and veggie casserole recipe is how easy it is to make your own. Feel free to swap veggies in or out based on what you have, or tweak it to fit dietary preferences — it’s a canvas waiting for your creativity.

• Use leftover or rotisserie chicken: This shortcut is a lifesaver on busy days, speeding up the cooking time and still keeping that creamy delicious flavor I adore.
• Make it dairy-free: I’ve swapped sour cream with coconut yogurt and used dairy-free condensed soups for friends with allergies — it still turns out creamy and comforting.
• Add cheese: For extra indulgence, sprinkle shredded cheddar or mozzarella on top before baking — my family goes crazy for the melty topping!
• Seasonal veggies: Swap bell peppers for zucchini or swap mushrooms for asparagus in spring — it’s all good and keeps things fresh.

How to Make Creamy Chicken and Veggie Casserole Recipe

Step 1: Preheat and Prep Your Ingredients

Start by preheating your oven to 375°F — this ensures it’s hot and ready when your casserole goes in. Meanwhile, chop your vegetables with care: onions, bell peppers sliced into strips, and mushrooms sliced for even sautéing. I like to pop the frozen spinach directly into a bowl of hot water while prepping everything else — it thaws quickly and makes draining so much easier.

Step 2: Sauté the Vegetables to Build Flavor

Heat a large pan over medium heat and melt the butter. Once it’s bubbly, toss in your garlic, onions, peppers, and mushrooms. Cook them until the onions turn translucent and the peppers soften, around 5 to 10 minutes. Then, squeeze out the excess water from your thawed spinach — I learned this trick the hard way by ending up with a soggy casserole! Mix the spinach in well and cook everything together for another minute or so.

Step 3: Prepare Your Chicken

While your veggies are doing their thing, cut the raw chicken breasts into bite-sized pieces. For a different twist, you can slice the chicken into larger 4 oz cutlets and layer them on top when assembling the casserole — I’ve done both, and the cutlet method makes for a fancier presentation. Just be sure to bake long enough so the chicken is cooked through.

Step 4: Mix the Sauce and Combine Everything

After the veggies are perfectly sautéed, off the heat, stir in the condensed cream of mushroom soup and the sour cream. Sprinkle in paprika, salt, and pepper, then mix everything thoroughly until you get a smooth, creamy sauce coating all the vegetables. If you’re mixing the chicken pieces in, add them now and stir until they’re well combined with the saucy veggies.

Step 5: Bake and Enjoy!

Spray a baking dish generously with non-stick spray and pour your mixture in. If you went the cutlet route, lay the cutlets on top instead. Pop it in the preheated oven for about 20 minutes or until the chicken is cooked through and bubbly around the edges. I always check the internal temp of the chicken to be safe! Serve it up on its own or over your favorite carbs — rice, noodles, or even cauliflower rice all make great pairings.

How to Serve Creamy Chicken and Veggie Casserole Recipe

Garnishes

I love adding a sprinkle of fresh parsley or chives on top before serving to add color and a pop of freshness that cuts through the creaminess. Sometimes, I add a bit of shredded cheese as garnish right after baking for extra indulgence, especially when serving company.

Side Dishes

This casserole pairs wonderfully with simple sides like garlic bread or a crisp green salad to balance the richness. I often serve it alongside steamed rice or buttery noodles which soak up the creamy sauce perfectly. For a low-carb option, cauliflower rice is a great match that I use regularly.

Creative Ways to Present

For family gatherings or dinner parties, I like to bake the casserole in individual ramekins for a charming single-serving presentation. Another favorite is layering the cutlet version atop cooked noodles in a deep dish, then topping with melted cheese for a beautiful, rustic look that’s bound to impress your guests.

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge and it keeps well for 3 to 4 days. Reheating is simple and the casserole retains its creamy texture without drying out when warmed gently on the stove or in the microwave with a splash of water or broth.

Freezing

I’ve successfully frozen this casserole before baking by assembling it and wrapping it tightly. When ready, just thaw overnight in the fridge and bake like usual. Alternatively, freezing cooked leftovers works great too — just reheat thoroughly until hot all the way through.

Reheating

To keep that creamy goodness on reheating, I reheat the casserole gently in a saucepan over low heat, stirring occasionally, adding a splash of milk or broth if it feels too thick. Microwaving works fine as well, but watch the time so it doesn’t overcook and dry out.
