My neighbor Gloria made this for every new mother on our street for thirty years. She finally shared the recipe at her retirement party.

After 25 minutes, carefully remove the foil (watch for steam). Give the sauce a gentle stir around the edges to keep it silky, then return the uncovered dish to the oven. Bake for another 15 to 20 minutes, or until the chicken is cooked through and the sauce is bubbling and slightly thickened. The top should have a rich golden hue with hints of paprika.

Check for doneness by cutting into a thicker piece of chicken; it should be white and opaque all the way through, with juices running clear, and an instant-read thermometer inserted into the largest piece should read at least 165°F (74°C).
Let the dish rest for 5 to 10 minutes on the counter before serving. The sauce will thicken slightly as it cools, turning silky and perfect for spooning over your side of choice. If using, sprinkle with chopped parsley just before bringing the dish to the table.
To serve, use a large spoon to scoop generous portions of chicken and sauce onto plates or over rice, noodles, or potatoes, making sure everyone gets plenty of that creamy, golden gravy.
Variations & Tips

To stay true to Gloria’s original, keep the base to just chicken, cream of chicken soup, and sour cream, but you can still play around the edges. For extra flavor, stir 1 teaspoon of garlic powder or onion powder into the sauce before baking, or swap in cream of mushroom or cream of celery soup for a slightly different vibe. If you prefer darker meat, use all boneless, skinless thighs; they’re very forgiving and stay juicy even if you accidentally bake a few minutes longer.

For a little color and sweetness, scatter 1 cup of sliced mushrooms or a handful of frozen peas over the chicken before pouring on the sauce (this will technically add ingredients, but the core 3-ingredient idea stays the same). To lighten it up a bit, you can use light sour cream, though the sauce will be slightly less rich and may separate a touch—stir it well after baking to bring it back together.

Leftovers keep well in the fridge for up to 3 to 4 days; reheat gently on the stovetop or in the microwave, adding a splash of milk or broth if the sauce has thickened too much. For food safety, always start with fully thawed chicken (never bake from frozen in this recipe), wash your hands and any surfaces that touch raw chicken, and cook until the internal temperature reaches at least 165°F (74°C).

Cool leftovers within 2 hours of baking and store them in a shallow container so they chill quickly. If you’re dropping this off for a new parent, include simple reheating instructions on a sticky note and pack the chicken in a tightly covered, oven-safe dish so they can warm it up without extra dishes.
