My aunt clipped this from a 1967 magazine and made it for every church potluck until the day she passed. Only 4 ingredients and it never once came hom

Elevate your weeknight dinner rotation with this incredibly rich and cozy Oven-Baked 4-Ingredient Chicken Royale. This comforting, retro-style casserole turns simple pantry staples into a decadent family feast with virtually zero hands-on effort.

By smothering tender chicken breasts in a velvety mixture of golden mushroom soup and tangy sour cream, you create a luscious, savory gravy right in the pan. Layering crispy French-fried onions both under and over the sauce ensures you get the perfect balance of savory, softened onion flavor inside the bake, and a deeply satisfying, buttery crunch on top.

Oven-Baked 4-Ingredient Chicken Royale

Ingredients:

Step-By-Step Directions:

1. Prep the Oven and Dish: Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch ceramic or glass baking dish with cooking spray or a thin swipe of oil.

2. Prepare the Chicken: Pat the chicken breasts dry with paper towels and trim off any excess fat. If they are very thick, slice them in half horizontally so they cook evenly and stay tender. Lay them flat in a single, snug layer in the prepared baking dish.

3. Mix the Sauce: In a medium bowl, stir together the condensed golden mushroom soup and the sour cream until completely smooth and combined.

4. Assemble the Casserole: Sprinkle about half of the crispy fried onions evenly over the raw chicken breasts. Pour the creamy soup and sour cream mixture directly over the chicken and onions, spreading it with a spoon or spatula to ensure every piece is thoroughly coated.

5. Initial Bake (Covered): Cover the casserole dish tightly with aluminum foil. Bake in the preheated oven for 30 minutes, or until the sauce is bubbling and the chicken is starting to turn opaque.

6. Add the Crispy Topping: Carefully remove the foil, then sprinkle the remaining crispy fried onions evenly over the top of the saucy chicken to form a generous, crunch-inducing layer.

7. Finish Baking (Uncovered): Return the uncovered dish to the oven and bake for another 15/20 minutes. The chicken should be completely cooked through (reading 165°F in the thickest part) and the onion topping should be beautifully golden and crisp.

8. Rest and Serve: Let the casserole rest on the counter for 5/10 minutes before serving to allow the rich, golden mushroom sauce to thicken slightly. Spoon generously over plates and enjoy!
