This oven-baked 3-ingredient chicken is pure Midwestern nostalgia. My neighbor, Mrs. B from down the block, brought a bubbling blue enamel casserole of this to our June block party in 1972, and it disappeared faster than the potato salad. The charm is in its simplicity: just chicken breasts, a pantry gravy shortcut, and a savory seasoning blend that caramelizes into a rich, spoonable sauce. It’s the kind of no-fuss recipe you pull out when you want something comforting, reliable, and crowd-pleasing without a long ingredient list or complicated prep.
Serve these tender, spoonable chicken breasts over a bed of fluffy white rice, buttered egg noodles, or mashed potatoes so they can soak up every bit of the savory gravy. A simple green salad with a bright vinaigrette or steamed green beans with lemon helps balance the richness. For a more old-school block party feel, pair it with corn on the cob, a crunchy coleslaw, and a basket of soft dinner rolls to swipe through the pan juices.
Oven-Baked 3-Ingredient Chicken Boulevard
Servings: 4

Ingredients
2 pounds boneless, skinless chicken breasts (about 4 medium pieces)
2 (10.5-ounce) cans condensed cream of chicken soup
2 tablespoons dry onion soup mix
Directions
Preheat your oven to 350°F (175°C). Lightly grease a blue speckled enamel 9x13-inch casserole dish, or a similar oven-safe dish, so the chicken doesn’t stick.
In a medium bowl, whisk together the condensed cream of chicken soup and the dry onion soup mix until the mixture is smooth and evenly combined. It will be thick and very flavorful—this is your gravy base.
Pat the chicken breasts dry with paper towels. This helps them brown a bit on top and keeps excess water out of the sauce.
Lay the chicken breasts in a single layer in the prepared casserole dish, leaving a little space between each piece so the sauce can flow around them.
Pour the soup and onion mix evenly over the chicken, using a spoon or spatula to spread it so each breast is well coated. The chicken should be mostly submerged, with the very tops just peeking out—those edges will pick up a bit of color in the oven.
Cover the dish tightly with foil and bake on the center rack for 35 minutes. Keeping it covered at first helps the chicken stay moist and allows the sauce to loosen into a silky gravy.
Remove the foil and return the dish to the oven. Bake uncovered for an additional 20–25 minutes, or until the chicken is cooked through (an instant-read thermometer should read 165°F / 74°C in the thickest part) and the sauce is bubbling around the edges.
For slight char and deeper color on the tops, move the dish to the upper third of the oven and broil on high for 2–4 minutes, watching closely so it doesn’t burn. You’re looking for some browned spots and a bit of caramelization on the chicken and sauce.
Let the chicken rest in the hot gravy for about 5–10 minutes before serving. This helps the juices redistribute and the sauce thicken slightly. Use a large spoon to scoop generous portions of chicken and gravy straight from the casserole dish to the plate.
Variations & Tips
To keep the spirit of the original 1972 block party dish, I stick to three ingredients, but there are still ways to adjust within that framework. If your chicken breasts are very large and thick, consider cutting them in half horizontally so they cook more evenly and stay tender. You can also swap condensed cream of chicken soup for cream of mushroom or cream of celery for a slightly different flavor profile while still using just three items. If you prefer darker meat, boneless, skinless chicken thighs work beautifully; they’re more forgiving and stay juicy, though they may need an extra 5–10 minutes of baking time depending on size. For a bit more browning without adding ingredients, simply extend the broil step by a minute or two, watching carefully. Food safety tips: Always thaw chicken completely in the refrigerator, never on the counter. Keep raw chicken and its juices away from ready-to-eat foods, and wash hands, cutting boards, and knives thoroughly with hot, soapy water after contact. Use an instant-read thermometer to ensure the chicken reaches 165°F (74°C) in the thickest part. Leftovers should be cooled quickly, refrigerated within 2 hours, and eaten within 3–4 days; reheat until steaming hot before serving.
