Ingredients

• 2 pounds boneless, skinless chicken breasts or chicken tenders
• 2 cans (10.5 ounces each) condensed cream of mushroom soup
• 1 cup sour cream
• 1 packet (1 ounce) dry onion soup mix

Instructions

1. Prepare the oven: Preheat your oven to 350°F (175°C). Lightly grease a deep 9 × 13-inch baking dish with cooking spray or butter.
2. Arrange the chicken: Place the boneless, skinless chicken breasts or tenders in a single layer in the prepared casserole dish.
3. Make the creamy sauce: In a medium mixing bowl, combine the condensed cream of mushroom soup, sour cream, and dry onion soup mix. Stir until smooth and evenly blended.
4. Cover the chicken: Pour the creamy mushroom mixture over the chicken, spreading it evenly so every piece is coated with sauce.
5. Bake covered: Cover the casserole tightly with aluminum foil and bake for 45 minutes.
6. Finish baking: Remove the foil and continue baking for another 15–20 minutes, until the sauce is bubbling and the chicken reaches an internal temperature of 165°F (74°C) in the thickest part.
7. Rest and serve: Allow the casserole to rest for approximately 5 minutes before serving. Spoon the tender chicken and creamy mushroom sauce over hot egg noodles, rice, or mashed potatoes.

Helpful Tips and Variations

Use boneless chicken thighs: For an extra-tender and flavorful casserole, substitute boneless, skinless chicken thighs for chicken breasts. They work beautifully with the creamy mushroom sauce.

Add fresh mushrooms: For a deeper mushroom flavor, add approximately 8 ounces of sliced fresh mushrooms around the chicken before pouring over the sauce.

Make it lighter: Choose reduced-fat sour cream and a lighter condensed cream of mushroom soup for a less rich version of this baked chicken dinner.

Avoid dry chicken: Chicken breasts can become dry if overcooked. Check the internal temperature with a meat thermometer and remove the casserole once the chicken reaches 165°F.

Prepare it ahead: Assemble the casserole several hours before dinner, cover tightly, and refrigerate. When baking directly from the refrigerator, allow approximately 10 additional minutes of covered baking time, checking the chicken for doneness.

What to Serve with Chicken Stroganoff Bake

This creamy chicken casserole pairs wonderfully with simple side dishes that complement its rich mushroom sauce.

• Buttered egg noodles for a traditional chicken stroganoff dinner.
• Fluffy white rice to soak up the savory mushroom gravy.
• Creamy mashed potatoes for an extra-comforting family meal.
• Steamed green beans for a fresh vegetable side.
• Roasted broccoli for a little color and texture.
• A crisp green salad to balance the creamy sauce.
• Warm dinner rolls to enjoy every last bit of gravy.

Storage and Reheating

Refrigerator: Store leftover chicken stroganoff bake in an airtight container for up to 3–4 days.

Freezer: Freeze cooled portions in freezer-safe containers for up to 2 months. The sour cream sauce may change texture slightly after thawing.

Reheating: Warm individual portions in the microwave or reheat the casserole in a 325°F oven, covered with foil, until heated through. Add a splash of milk or chicken broth if the sauce becomes too thick.

Frequently Asked Questions

Can I use chicken thighs instead of chicken breasts?

Yes! Boneless, skinless chicken thighs are an excellent substitute. They stay tender and juicy and add a slightly richer flavor to the casserole.

Can I make chicken stroganoff bake ahead of time?

Absolutely. Assemble the casserole, cover it, and refrigerate for several hours before baking. Add extra baking time if starting with a cold dish.

What is the best side dish for chicken stroganoff?

Egg noodles are a traditional choice, but rice and mashed potatoes are equally delicious because they absorb the creamy mushroom sauce.

How do I know when the chicken is done?

Use an instant-read thermometer to check the thickest part of the chicken. It should reach 165°F (74°C) before serving.

Can I add vegetables to this chicken casserole?

Yes. Fresh mushrooms, sliced onions, peas, or green beans can add extra flavor and texture. Adjust the baking time if you add substantial quantities.
