This oven baked 3-ingredient chicken country club is the kind of comforting casserole-style supper that earns a permanent place in a family recipe box. It is simple, budget-friendly, and full of old-school flavor, with juicy chicken baked under a creamy mushroom sauce and sweet tender onions until everything turns rich and golden. Recipes like this became church-supper and auxiliary favorites for good reason: they feed a crowd with very little fuss, and they always feel like home.
Serve this chicken over mashed potatoes, buttered egg noodles, rice, or even thick slices of toast to catch every bit of the creamy sauce. A green vegetable like peas, green beans, or steamed broccoli makes a nice balance, and a simple tossed salad or applesauce on the side rounds it out beautifully for a family-style meal.
Oven Baked 3-Ingredient Chicken Country Club
Servings: 6
Ingredients
2 1/2 to 3 pounds chicken pieces, bone-in or boneless
1 large onion, thinly sliced
2 cans (10.5 ounces each) condensed cream of mushroom soup
Directions
1. Preheat the oven to 350 degrees Fahrenheit and lightly grease a 9x13-inch baking dish or a similar large casserole dish.
2. Arrange the chicken pieces in the baking dish in a single layer, then scatter the sliced onion evenly over the top.
3. Spoon the cream of mushroom soup over the chicken and onions, spreading it gently so most of the surface is covered.
4. Cover the dish with foil and bake for 45 minutes. Remove the foil and continue baking for 20 to 30 minutes more, or until the chicken is fully cooked and the top is bubbling and lightly golden.
5. Let the dish rest for 5 to 10 minutes before serving so the sauce settles a bit. Spoon the chicken and sauce onto plates and serve hot.
Variations & Tips
For extra seasoning: If your family likes a little more flavor, add black pepper, garlic powder, or a pinch of paprika before baking. The classic version keeps things very simple, but a little seasoning can give it a deeper savory taste.
For picky eaters: If sliced onions are a hard sell, tuck them underneath the chicken so they melt into the sauce as it bakes. You still get the flavor, but the texture is much less noticeable on the plate.
For a heartier meal: You can add baby potatoes or serve the chicken over cooked rice or noodles to stretch the dish a little further. This is especially handy when you are feeding teenagers or bringing dinner to a gathering.
For browner chicken: If you want more color on top, place the dish under the broiler for 1 to 2 minutes at the very end, watching closely. That quick finish can give the casserole a prettier golden look without drying it out.
Make-ahead tip: Assemble the dish a few hours ahead, cover, and refrigerate until baking time. If it is going into the oven cold from the refrigerator, add a little extra baking time so the chicken cooks through evenly.
