End of Summer Bake: Only 3 ingredients. I pop this in the oven when I want a hearty meal without standing over a hot stove all afternoon.

This simple three-ingredient bake is the kind of hearty, no-fuss supper that feels right at home at the end of summer, when everyone is hungry but nobody wants to linger over a hot stove. Inspired by old-school casserole cooking and that cozy 1970s baked-dinner spirit, it layers tender concealed baked protein under a rich, savory topping that turns beautifully browned and bubbly in the oven.

Serve this warm bake with green beans, a crisp garden salad, buttered corn, or sliced tomatoes to balance its richness. If you want to stretch it for a bigger family meal, add dinner rolls, roasted potatoes, or simple fruit on the side for an easy supper table.

Ingredients

2 pounds boneless skinless chicken thighs
1 (10.5 ounce) can condensed cream of mushroom soup
1 (6 ounce) can French fried onions

Chicken thighs, cream of mushroom soup, and fried onions on a kitchen counter

Directions

1. Preheat the oven to 375°F and lightly grease a medium ceramic baking dish.

2. Arrange the chicken thighs in an even layer in the baking dish so they cover the bottom.

3. Spoon the condensed cream of mushroom soup over the chicken and spread it gently to cover the meat as evenly as possible.

4. Sprinkle the French fried onions evenly over the top to create a full crust.

5. Bake uncovered for 40 to 45 minutes, until the chicken is cooked through and the top is deep golden brown and bubbling. Let it rest for 5 minutes before serving.

Variations & Tips

Beefy Version: Swap the chicken thighs for thin boneless pork chops or cooked meatballs if that is what you have on hand. Just be sure the protein reaches a safe internal temperature before serving.

For Picky Eaters: Crush part of the fried onions before sprinkling them on top for a finer, more even crust that feels a little less noticeable while still giving plenty of flavor and crunch.

Extra Comforting: If you do not mind stepping beyond three ingredients, this bake is especially good spooned over cooked rice, egg noodles, or mashed potatoes to catch the creamy sauce.

Make-Ahead Tip: Assemble the chicken and soup in the baking dish a few hours ahead, cover, and refrigerate. Add the fried onions right before baking so the topping stays crisp and browns nicely.
