This oven baked 4-ingredient Amish chicken and squash casserole is the kind of comforting dish a church friend might drop off during spring cleaning when life feels a little extra busy. It’s unbelievably creamy, uses just a few pantry staples, and bakes up into tender chicken nestled with soft yellow squash under a bubbly, golden sauce. The recipe is inspired by the simple, practical casseroles you find at small-town church potlucks—nothing fancy, just real food that completely hits the spot on a weeknight.
Serve this casserole straight from the oven with a simple green salad or steamed green beans to balance the creaminess. Warm dinner rolls or buttered bread are perfect for soaking up the extra sauce. If you want to stretch the meal a bit, spoon the chicken and squash over plain white rice, buttered egg noodles, or mashed potatoes. A little dish of applesauce or sliced fresh fruit on the side keeps the plate kid-friendly and adds a touch of sweetness.
Oven Baked 4-Ingredient Amish Chicken and Squash CasseroleServings: 4-6
Ingredients
2 pounds boneless, skinless chicken breasts or thighs, cut into large bite-size pieces
4 cups thinly sliced yellow summer squash (about 3–4 medium squash)
2 cans (10.5 ounces each) condensed cream of chicken soup
1 cup full-fat sour cream
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch white casserole dish or similar baking dish.
In a medium bowl, whisk together the condensed cream of chicken soup and sour cream until smooth and well combined. This will be your creamy sauce.
Spread the sliced yellow squash evenly over the bottom of the prepared casserole dish, making a single, fairly even layer. This gives you a tender vegetable base under the chicken.
Arrange the chicken pieces in an even layer over the squash. It’s fine if they overlap a bit, but try not to pile them too high in one spot so they cook evenly.
Pour the soup and sour cream mixture over the chicken and squash. Use a spatula or the back of a spoon to gently spread the sauce so everything is well coated and you don’t see any dry spots.
Cover the casserole dish tightly with foil. Bake in the preheated oven for 35 minutes to let the chicken cook through and the squash soften in the creamy sauce.
After 35 minutes, carefully remove the foil and return the dish to the oven. Bake uncovered for another 15–20 minutes, or until the top is bubbly, lightly golden in spots, and the chicken is cooked through (reaching 165°F/74°C in the thickest pieces). The squash should be very tender.
Let the casserole rest for 5–10 minutes before serving. This short rest helps the sauce thicken slightly and makes it easier to scoop out neat portions of tender chicken, soft squash, and creamy sauce.
Variations & Tips
If you have picky eaters, you can cut the squash into half-moons or smaller pieces so it blends in more with the chicken. For a slightly richer flavor, use chicken thighs instead of breasts—they stay very tender in the creamy sauce. If you like a little color on top, you can broil the casserole for 1–2 minutes at the end of baking (watch closely) to deepen the golden spots on the sauce. To lighten things up a bit, you can use light sour cream and one can of cream of chicken soup plus one can of cream of mushroom soup for a different but still very creamy flavor. For extra seasoning without adding more ingredients, sprinkle a small pinch of salt and pepper over the chicken before adding the sauce, or use a low-sodium condensed soup if your family is watching salt. Leftovers reheat well in the oven or microwave and can be tucked into tortillas or served over rice for a second, easy meal.
