This oven baked 3-ingredient Chicken Royale is exactly the kind of old-school dinner that earns a permanent spot in the family rotation. It has that classic mid-century casserole charm: tender chicken, a rich creamy mushroom sauce, and a beautifully golden top that feels a little fancy without asking much from you. It is the sort of recipe that makes a busy weeknight feel manageable but still special enough for Sunday dinner, which is probably why so many home cooks held onto versions of it for decades.
Serve Chicken Royale with mashed potatoes, buttered egg noodles, or steamed rice to catch every bit of the creamy sauce. For vegetables, simple green beans, roasted broccoli, or a crisp side salad work well and keep the plate balanced. If you want to lean into the comfort-food feel, warm dinner rolls on the side are hard to beat.
Oven Baked 3-Ingredient Chicken Royale
Servings: 4
Ingredients
4 boneless, skinless chicken breasts
1 can (10.5 ounces) condensed cream of mushroom soup
1 cup sour cream
Directions
1. Preheat the oven to 350°F and lightly grease a white oval casserole dish large enough to hold the chicken in a single layer.
2. Arrange the chicken breasts in the prepared dish. In a medium bowl, stir together the condensed cream of mushroom soup and sour cream until smooth.
3. Spoon the sauce evenly over the chicken, covering each piece well so it stays moist while baking.
4. Bake uncovered for 40 to 50 minutes, or until the chicken is cooked through and the top is lightly golden and bubbling around the edges.
5. Let the dish rest for 5 minutes before serving, then spoon the sauce over the chicken and plate with mashed potatoes or noodles.
Variations & Tips
Add a little seasoning: If you keep a few pantry basics on hand, a pinch of black pepper, garlic powder, or onion powder can give the sauce a little extra depth without changing the spirit of the recipe.
Use chicken thighs: Boneless, skinless chicken thighs work well here and usually stay extra juicy. They may cook a little faster or slower depending on size, so check for doneness rather than relying only on the clock.
Make it meal-prep friendly: You can assemble the dish earlier in the day, cover it, and refrigerate until dinnertime. When baking from cold, add a few extra minutes so the center heats through evenly.
Thin the sauce if needed: If you prefer a looser sauce for serving over rice or noodles, stir in 2 to 4 tablespoons of milk before pouring it over the chicken.
Check doneness the easy way: The safest and simplest method is using an instant-read thermometer. Chicken is ready when the thickest part reaches 165°F.
