Ingredients

• 2 pounds boneless, skinless chicken breasts or chicken thighs, cut into large pieces

• 1 packet (1 ounce) dry onion soup mix

5. Cover the casserole loosely with aluminum foil and bake for 35 minutes.
6. Remove the foil and continue baking for another 15–20 minutes, or until the chicken reaches a safe internal temperature and the sauce is hot and bubbling.
7. Let the casserole rest for 5–10 minutes before serving.
8. Serve over cooked rice, mashed potatoes, or buttered egg noodles.

What to Serve With Chicken Madeira Casserole

This creamy chicken casserole pairs beautifully with:

• Steamed green beans
• A simple green salad
• Roasted vegetables
• Mashed potatoes
• Buttered egg noodles
• White or brown rice
• Warm dinner rolls

Recipe Tips

Use chicken thighs for extra tenderness: Chicken thighs are naturally juicy and work especially well in casseroles. Chicken breasts are also a great choice if you prefer leaner meat.

Cut the chicken evenly: Large, similarly sized pieces help the chicken cook more evenly.

Don’t overbake: Start checking the chicken toward the earlier end of the cooking time. Overcooking can make chicken breasts dry.

Make it ahead: Assemble the casserole earlier in the day, cover it, and refrigerate until you’re ready to bake. If baking directly from the refrigerator, allow additional cooking time and make sure the center is completely hot.

Make it family-friendly: If your family doesn’t like mushroom pieces, omit the jarred mushrooms while keeping the cream of mushroom soup for its savory flavor and creamy texture.

Stretch the meal: Serve the chicken and sauce over rice or egg noodles to make the dish more filling and economical.
