This is the very same creamy, salty, company-worthy chicken that sat on every church basement buffet line back in the mid-1970s. Around here it showed up at funerals, baby showers, and especially potlucks where every woman swore her version was just a little bit better than the next. My Aunt Ruth guarded her exact proportions for years, but last week she finally let me write them down. It’s pure Midwestern comfort: tender baked chicken breasts tucked into a bed of chipped beef and smothered in a rich sour-cream gravy that bubbles up golden around the edges. Five ingredients, one glass casserole dish, and you’ve got the kind of “party chicken” that disappears before the Jell-O salad even makes it down the line.
Serve this party chicken over a bed of fluffy white rice, buttered egg noodles, or good old mashed potatoes so every bit of that creamy sauce has somewhere to go. On the side, simple green beans, a tossed salad, or buttered peas keep it feeling like a classic church supper plate. A basket of warm dinner rolls or soft white bread is perfect for soaking up the sauce. For a true 1975-style spread, round things out with a molded salad, a pan of brownies, or a dump cake for dessert, and a pot of coffee or sweet tea on the table.
Oven-Baked 5-Ingredient Party ChickenServings: 6
Ingredients
8 ounces jarred chipped beef, rinsed and roughly chopped
6 boneless, skinless chicken breasts (about 2 1/2 to 3 pounds total)
8 tablespoons (1 stick) unsalted butter, sliced
2 (10.5-ounce) cans condensed cream of mushroom soup
1 1/2 cups sour cream (full-fat recommended)
Optional: freshly ground black pepper, to taste
Directions
Preheat your oven to 300°F (150°C). Lightly grease a 9x13-inch glass casserole dish.
Prepare the chipped beef: Rinse the chipped beef briefly under cool running water to remove some of the salt, then pat it dry with paper towels. Roughly chop or tear it into bite-size pieces.
Layer the beef: Spread the chopped chipped beef evenly over the bottom of the prepared casserole dish. This makes a salty, savory bed for the chicken.
Arrange the chicken: Lay the chicken breasts in a single layer over the chipped beef. If some pieces are very thick, you can gently pound them to an even thickness so they cook evenly. Sprinkle lightly with black pepper if you like; you don’t need extra salt because the beef is salty.
Dot with butter: Distribute the butter slices evenly over the tops of the chicken breasts. As the chicken bakes, the butter melts down and enriches the sauce.
Mix the sauce: In a medium bowl, stir together the condensed cream of mushroom soup and the sour cream until smooth and well combined.
Add sauce to casserole: Pour the sour cream–soup mixture over the chicken, spreading it gently with a spatula so every piece is covered and the sauce reaches down around the sides.
Bake low and slow: Cover the casserole tightly with foil and bake in the preheated 300°F oven for 1 1/2 hours. This gentle heat keeps the chicken tender and lets the flavors meld.
Uncover to finish: After 1 1/2 hours, remove the foil and continue baking for another 20–30 minutes, or until the sauce is bubbling, lightly golden around the edges, and the chicken is cooked through (an instant-read thermometer inserted in the thickest part should read 165°F).
Rest and serve: Let the casserole rest for about 10 minutes so the sauce can settle and thicken slightly. Serve the chicken breasts hot with plenty of the creamy chipped beef sauce spooned over each portion.
Variations & Tips
To keep the spirit of that 1975 church potluck table, the base recipe stays simple, but there’s room for small tweaks. You can use bone-in chicken pieces instead of boneless breasts; just allow extra baking time and always cook to an internal temperature of 165°F. If you prefer a milder salt level, rinse the chipped beef a bit longer or soak it in cool water for 5–10 minutes, then drain and pat dry. Cream of chicken or cream of celery soup can stand in for the cream of mushroom, or use one can of each for a different flavor. For a little extra color, sprinkle a bit of paprika or dried parsley over the top before baking. If you need to stretch the dish for a crowd, slice the cooked chicken and return it to the pan, stirring it into the sauce so everyone can take a smaller portion with plenty of gravy over rice or noodles. Food safety tips: Always thaw chicken in the refrigerator, not on the counter. Keep raw chicken and its juices away from ready-to-eat foods and wash hands, knives, and cutting boards thoroughly with hot, soapy water after handling. Use a food thermometer to confirm the thickest part of each piece reaches 165°F before serving. If you’re holding this on a buffet, keep it hot above 140°F and refrigerate leftovers within 2 hours; reheat leftovers to 165°F before eating.
