My aunt brought this to every church dinner from 1968 until she passed. Three ingredients and the ladies auxiliary still talks about it.

This oven baked 3-ingredient chicken continental elegante is the sort of dish that lived on church supper tables from the late 1960s straight through the potluck boom of the 80s. Think of it as a Midwestern take on French-style creamy chicken: simple pantry staples, a short ingredient list, and just enough elegance to feel special without being fussy. The entire ladies auxiliary could tell you who made it by the aroma alone—tender chicken, sweet onions, and a silky mushroom cream sauce bubbling together in a white casserole dish. It’s ideal for busy weeknights, but nostalgic enough for a Sunday dinner when you want something comforting and familiar.

Serve this chicken over buttered egg noodles, mashed potatoes, or simple steamed rice so all that silky mushroom-onion sauce has something to soak into. A crisp green salad with a light vinaigrette or some steamed green beans balances the richness nicely. Warm dinner rolls or a crusty baguette are welcome for mopping up the extra sauce, and if you’re leaning into the retro potluck spirit, a classic gelatin salad or a simple fruit salad makes a charming, period-appropriate side.

Servings: 6

3 pounds bone-in, skin-on chicken pieces (thighs and drumsticks work best)

Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch white ceramic casserole dish or similar baking dish.

Scatter the thinly sliced onions evenly over the bottom of the casserole dish, creating a bed for the chicken. This keeps the chicken elevated and lets the onions soften into the sauce as they bake.

Arrange the chicken pieces skin-side up on top of the onions in a single layer. It’s fine if they fit snugly, but avoid stacking so they cook evenly.

In a medium bowl, whisk or stir the condensed cream of mushroom soup until smooth. You are using it straight from the can—do not dilute it with water or milk. Spoon or pour the soup evenly over the chicken, letting it drip down between the pieces and onto the onions. Use the back of the spoon to spread the soup so most of the chicken is coated, leaving some of the skin exposed so it can brown.

Cover the casserole dish tightly with foil. Bake, covered, for 45 minutes. The sauce will loosen and the onions will begin to soften underneath the chicken.

After 45 minutes, carefully remove the foil (watch for steam). Continue baking the chicken uncovered for 25–35 minutes more, or until the chicken is cooked through, the skin is golden brown in spots, and the sauce is bubbling and silky. The internal temperature of the thickest pieces should reach at least 165°F (74°C).

Once done, remove the casserole from the oven and let it rest for about 5–10 minutes. This allows the juices to settle and the sauce to thicken slightly.

To serve, use a large serving spoon to lift chicken pieces along with plenty of the creamy mushroom-onion sauce from underneath. Spoon over noodles, rice, or potatoes, making sure each portion gets some of the tender onions and golden, juicy chicken.

If you’d like to tweak this classic while staying true to its three-ingredient spirit, you can swap the cream of mushroom soup for cream of celery or cream of chicken for a slightly different flavor profile, or use a mix of two different condensed soups as long as the total amount remains the same. Bone-in thighs and drumsticks are traditional because they stay juicy and create a richer sauce, but you can substitute bone-in chicken breasts; just watch the timing, as large breasts may take a little longer to reach 165°F in the thickest part. If you must use boneless, skinless pieces, reduce the covered baking time by about 10–15 minutes and know that the sauce will be a bit thinner and the top less golden without the rendered chicken fat and skin. For a slightly lighter feel, you can skim some fat from the surface of the sauce before serving. Food safety tips: Always thaw chicken completely in the refrigerator, never on the counter. Pat the chicken dry before placing it in the dish so it browns better and doesn’t steam. Use a clean cutting board and knife for the onions after handling raw chicken, or wash thoroughly with hot, soapy water in between to avoid cross-contamination. Check doneness with an instant-read thermometer inserted into the thickest part of the meat, avoiding the bone; the chicken should reach at least 165°F (74°C). Refrigerate leftovers within 2 hours of cooking and reheat until steaming hot before serving.
