This oven baked 3-ingredient chicken fricassee is the kind of quietly brilliant recipe that anchored a lot of Midwestern Sunday dinners. It’s not a classical French fricassee with wine and herbs, but a pared-down, church-supper version: bone-in chicken, onions, and a can of cream of mushroom soup that turns into a silky, pale golden gravy while it bakes. Everything happens in one casserole dish, the oven does the work, and you end up with tender chicken and soft, sweet onions under a spoonable, self-made sauce—exactly the kind of comfort food a grandmother could make every week for 40 years without getting tired of it.

Serve this chicken fricassee straight from the casserole dish with plenty of something starchy to catch the gravy—mashed potatoes, buttered egg noodles, or steamed white rice all work beautifully. A simple green vegetable like peas, green beans, or a tossed salad balances the richness. Warm dinner rolls or crusty bread are perfect for swiping up the last of the silky sauce in the bottom of the dish.
Oven Baked 3-Ingredient Chicken Fricassee
Servings: 4
Ingredients
8 bone-in, skin-on chicken thighs (about 2 1/2 to 3 pounds)
2 large yellow onions, thinly sliced
1 can (10.5 ounces) cream of mushroom soup
Directions
Preheat your oven to 350°F (175°C). Lightly grease a medium white oval or rectangular casserole dish so the chicken and onions don’t stick.

Scatter the thinly sliced onions evenly over the bottom of the casserole dish. This onion bed will soften and sweeten in the oven and help flavor the gravy.
Arrange the chicken thighs on top of the onions in a single layer, skin side up. Nestle them in so they’re touching but not stacked; this helps them cook evenly and keeps the meat moist.

Spoon the cream of mushroom soup over the chicken pieces, dividing it fairly evenly. Use the back of the spoon to gently spread the soup so most of the chicken and some of the onions are lightly coated. Don’t add water or extra liquid—the chicken juices will thin the soup into a creamy gravy as it bakes.
Cover the casserole dish tightly with foil. Bake, covered, for 45 minutes. During this time, the chicken will release juices, the onions will soften, and the soup will melt down into a pale golden, silky sauce.

After 45 minutes, carefully remove the foil (watch for steam). Baste the chicken by spooning some of the developing gravy over the tops of the thighs. Return the dish to the oven, uncovered, and bake for another 25 to 35 minutes, or until the chicken is very tender, the onions are soft, and the sauce is bubbling and slightly thickened.
Check that the chicken is fully cooked: the internal temperature at the thickest part of a thigh (not touching the bone) should reach at least 165°F (74°C), and the juices should run clear when pierced.

Once done, let the casserole rest for 5 to 10 minutes out of the oven. This short rest allows the gravy to settle and thicken slightly. To serve, use a wooden spoon or large serving spoon to lift a chicken thigh, making sure to scoop up plenty of the onions and silky sauce from underneath.
Variations & Tips
This recipe is intentionally stripped down to three ingredients, but you can adjust it gently without losing its spirit. If you prefer a slightly deeper flavor, you can brown the chicken thighs skin-side down in a skillet for a few minutes before arranging them over the onions; just know that this adds a step and a pan beyond what many grandmothers bothered with. For a different but still classic flavor, swap the cream of mushroom soup for cream of chicken or cream of celery soup.

If your family likes a looser sauce, stir in 1 to 2 tablespoons of water or milk into the soup before spooning it over the chicken; for a thicker, more clingy gravy, simply bake a bit longer uncovered at the end. You can also use a mix of chicken thighs and drumsticks, keeping the total weight about the same; avoid boneless, skinless cuts here, as they won’t give off as much flavor or richness to create that self-made gravy.
For food safety, always keep raw chicken refrigerated until you’re ready to bake, wash your hands and any surfaces or utensils that touched the raw poultry, and use a dedicated cutting board for meat when possible. Make sure the chicken reaches at least 165°F (74°C) in the thickest part, and promptly refrigerate leftovers within 2 hours in a shallow container; reheat thoroughly before serving.
