This 4-ingredient oven chicken is the kind of dependable dinner that saves the day when you need something easy, filling, and family-friendly without a lot of fuss. Using raw chicken breast tenderloins keeps the prep simple and the baking time shorter, while a few pantry staples turn everything into a flavorful, juicy casserole-style main dish that feels comforting on a busy weeknight.
Serve this chicken with mashed potatoes, buttered noodles, rice, or roasted vegetables to soak up the savory sauce in the dish. For a simple family supper, I also like adding a green salad or steamed green beans, and a basket of warm rolls on the table makes it feel extra cozy.
4-Ingredient Oven Chicken
Servings: 4 to 6
Ingredients
1 1/2 to 2 pounds raw chicken breast tenderloins
Directions
1. Preheat your oven to 375 degrees Fahrenheit and lightly grease a glass casserole dish.
2. Arrange the raw chicken breast tenderloins in an even layer in the prepared casserole dish.
3. In a medium bowl, stir together the dry onion soup mix, cream of chicken soup, and sour cream until smooth.
4. Spread the mixture evenly over the chicken, covering the tenderloins as completely as you can.
5. Bake uncovered for 35 to 45 minutes, or until the chicken is cooked through and reaches an internal temperature of 165 degrees Fahrenheit.
6. Let the dish rest for 5 minutes before serving so the sauce can settle a bit.
Variations & Tips
For picky eaters: If your family prefers milder flavors, use a little less of the onion soup mix or spread extra sour cream over the top before baking for a gentler, creamier finish.
Add a vegetable: You can tuck green beans, sliced mushrooms, or broccoli florets around the chicken before baking to turn this into more of a one-dish meal. Just make sure the vegetables are cut small enough to cook in the same amount of time.
Keep it juicy: Since tenderloins cook fairly quickly, start checking for doneness at the 35-minute mark so they do not overbake. A quick-read thermometer is the easiest way to make sure the chicken stays tender.
Make it extra cozy: This sauce is especially good spooned over rice, egg noodles, or mashed potatoes, so do not let any of it go to waste. If the sauce thickens too much after baking, stir in a splash of warm milk before serving.
Storage tip: Store leftovers covered in the refrigerator for up to 3 days. Reheat gently in the microwave or in a low oven, adding a spoonful of milk or broth if needed to loosen the sauce.
