This oven baked 4-ingredients creamy pea chicken is the kind of neighborly casserole that used to show up on our porch steps when a baby was born or a storm knocked the power out. My neighbor Marlene brought this over one chilly March evening, the whole dish still warm and bubbling, and I knew after the first bite I had to have her secret. It’s pure Midwestern comfort: tender chicken breasts baked under a blanket of creamy white sauce and sweet green peas, all in one pan. With just four simple ingredients and almost no fuss, it feels like the sort of church-supper classic our mothers and grandmothers leaned on when they needed something dependable, filling, and kind to the budget.
Serve this creamy pea chicken straight from the casserole dish with a big spoon, letting that sauce spill over something starchy and simple: buttered egg noodles, fluffy mashed potatoes, or plain white rice all soak up the gravy beautifully. A side of steamed carrots or green beans fits right in with the old-fashioned supper feel, and a pan of warm dinner rolls or biscuits never hurts. If you like a little color on the table, a crisp lettuce salad with a light vinaigrette balances the richness of the creamy sauce.
Oven Baked 4-Ingredients Creamy Pea ChickenServings: 4
Ingredients
4 boneless skinless chicken breasts (about 2 pounds total)
1 (10.5-ounce) can cream of chicken soup
1/2 cup sour cream
1 1/2 cups frozen peas (no need to thaw)
Salt and black pepper, to taste (optional, does not count toward 4 ingredients)
Nonstick cooking spray or a little butter for greasing the dish (optional, does not count toward 4 ingredients)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a medium casserole dish (about 9x13 inches or similar) with nonstick spray or a little butter so the chicken doesn’t stick.
Pat the chicken breasts dry with paper towels. If they are very thick, you can gently pound them to an even thickness so they cook more evenly. Season both sides lightly with salt and black pepper if you like.
In a medium bowl, stir together the cream of chicken soup and sour cream until smooth and well combined. This is your simple creamy sauce base.
Spread a very thin layer (a couple of spoonfuls) of the sauce over the bottom of the casserole dish. Lay the chicken breasts in a single layer on top of the sauce.
Pour the remaining sauce over the chicken, spreading it with a spoon so each piece is well covered. You want the chicken smothered in that creamy mixture.
Sprinkle the frozen peas evenly over the top of the sauced chicken. They will sink down and nestle into the sauce as it bakes, staying bright and tender.
Cover the casserole dish tightly with foil. Bake in the preheated oven for 25 minutes.
After 25 minutes, carefully remove the foil and return the dish to the oven. Bake uncovered for another 15–20 minutes, or until the chicken is cooked through (the internal temperature should reach 165°F/74°C and the sauce is bubbling around the edges).
Once done, remove the casserole from the oven and let it rest for about 5–10 minutes. The sauce will thicken slightly as it cools and the peas will stay a lovely bright green.
Serve the chicken breasts spooned with plenty of the creamy pea sauce over your choice of noodles, rice, or potatoes. Scoop from the casserole dish while it’s still warm and enjoy that cozy, neighborly comfort.
Variations & Tips
For a richer flavor, you can swap the cream of chicken soup for cream of mushroom or cream of celery, or use a mix of two cans if you’re doubling the recipe for a crowd. If you prefer dark meat, boneless skinless chicken thighs work beautifully and stay very tender; just add 5–10 minutes to the baking time and check for doneness. To stretch the meal, slice the chicken into thick strips or chunks before baking so the sauce coats more pieces and everyone gets some in each scoop. If you like a little tang, use plain Greek yogurt in place of some or all of the sour cream. For a slightly fancier touch that still keeps the spirit of the original, sprinkle a small handful of grated Parmesan or mild shredded cheese over the top during the last 5–10 minutes of baking so it melts into the sauce. You can also add a cup of sliced mushrooms or a handful of chopped onions under the sauce if you have them on hand, though the beauty of this dish is how satisfying it is with just the four main ingredients. Leftovers reheat well in a low oven or gently on the stovetop with a splash of milk to loosen the sauce.
