Found this in my mother-in-law’s recipe box from 1965 and now I understand why she made it every single Sunday.. Full recipe 👇 💬

This oven baked 3-ingredient chicken spectacular is one of those quiet little treasures that used to sit on handwritten cards in metal recipe boxes all across the Midwest. I first saw it in my mother-in-law’s box, dated 1965, written in her neat blue ink with a few splatters from years of Sunday suppers. It’s the kind of recipe a busy farm wife could pull together after church: simple pantry ingredients, no fussy steps, and a smell that fills the whole house.
The chicken bakes up golden and tender under a caramelized onion soup glaze that bastes it as it cooks. You make this when you want something comforting, reliable, and just old-fashioned good.

Serve this chicken straight from the glass baking dish with a big spoon for that glossy onion glaze. It’s wonderful over fluffy mashed potatoes or buttered egg noodles to catch all the drippings. On the side, think like a 1960s Sunday table: a green vegetable such as buttered peas, green beans, or a simple tossed salad, and maybe warm dinner rolls to mop up the sauce.
Leftovers make a fine next-day lunch tucked into a soft roll with a bit of the onion gravy spooned over the top.
Oven Baked 3-Ingredient Chicken
Servings: 4-6
Ingredients
3 to 4 pounds bone-in chicken pieces (legs, thighs, or bone-in breasts, skin on)
1 (10.5-ounce) can condensed cream of chicken soup
1 (1-ounce) packet dry onion soup mix
Directions
Preheat your oven to 350°F (175°C). Set out a 9x13-inch glass baking dish.
Pat the chicken pieces dry with paper towels. This helps the skin brown and keeps the sauce from getting too watery. Arrange the chicken in a single layer in the glass baking dish, skin side up, with a little space between pieces if possible.

In a medium bowl, stir together the condensed cream of chicken soup and the dry onion soup mix until well combined. It will be thick and speckled with onion bits.
Spoon or pour the soup mixture evenly over the chicken pieces, spreading it so each piece is well coated. The bottom of the dish will have some sauce around the chicken, which will turn into a rich glaze as it bakes.
Cover the baking dish tightly with foil and place it on the middle rack of the preheated oven. Bake covered for 45 minutes. This helps the chicken cook through and stay juicy while the flavors soak in.

After 45 minutes, carefully remove the foil (watch for steam). Baste the chicken by spooning some of the pan sauce over the tops of the pieces. Return the dish to the oven, uncovered.
Continue baking, uncovered, for another 25 to 35 minutes, or until the chicken is cooked through, the skin is golden, and the onion soup glaze is bubbling and starting to caramelize around the edges. The internal temperature of the thickest part of the chicken should reach at least 165°F (74°C).

If you’d like the top a bit more browned, you can move the dish up one rack for the last 5 to 10 minutes, keeping a close eye so the glaze doesn’t burn.
Remove the dish from the oven and let the chicken rest for about 5 to 10 minutes. The sauce will thicken slightly as it cools. Spoon the caramelized onion glaze over the chicken when serving, making sure each portion gets some of the rich juices from the bottom of the dish.
Variations & Tips
You can use almost any bone-in chicken pieces you like, but dark meat (thighs and legs) stays especially moist and forgiving, much like the Sunday dinners many of us grew up with. If you only have boneless, skinless chicken breasts, reduce the covered bake time to about 30 minutes and the uncovered time to 15–20 minutes, watching closely so they don’t dry out.
For a slightly tangier flavor, stir 2 to 3 tablespoons of sour cream or plain yogurt into the soup mixture before baking (this will make it more like the later 1970s versions of this dish). If you prefer a bit more color, sprinkle a little paprika over the chicken before adding the sauce. You can also tuck a few peeled carrot chunks or quartered onions around the chicken in the dish; they’ll roast in the sauce and soak up the flavor, though this technically adds more ingredients beyond the base three.

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 your hands, cutting boards, and utensils thoroughly with hot, soapy water after handling. Use a food thermometer to ensure the internal temperature of the thickest piece reaches at least 165°F (74°C). Refrigerate leftovers within 2 hours and use within 3 to 4 days, reheating until hot and steaming before serving.
