This 4-ingredient oven chicken is the kind of simple dinner that saves a busy evening and still feels like you put real care into the meal. Using raw diced chicken breast baked right in a glass dish with a few pantry staples keeps prep easy, cleanup light, and the flavor surprisingly big. It has that comforting casserole-style appeal many home cooks love, especially when you need a dependable family supper made from ingredients you may already have on hand.
This chicken pairs nicely with steamed rice, buttered noodles, mashed potatoes, or roasted vegetables, since the savory sauce can soak right in and make the whole plate taste complete. For a lighter meal, serve it with a crisp green salad or simple green beans, and if you are feeding hungry kids or teens, warm dinner rolls on the side are always a welcome addition.
4-Ingredient Oven Chicken
Servings: 4
Ingredients
1 1/2 pounds raw chicken breast, diced into bite-size pieces
1 packet dry onion soup mix, about 1 ounce
1 cup mayonnaise
1/2 cup grated Parmesan cheese
Directions
1. Preheat the oven to 375°F and lightly grease a 9x13-inch glass baking dish.
2. Spread the diced raw chicken breast evenly in the prepared baking dish.
3. In a medium bowl, stir together the dry onion soup mix, mayonnaise, and grated Parmesan cheese until well combined.
4. Spoon the mixture over the chicken and gently toss or spread it so the chicken pieces are coated as evenly as possible.
5. Bake uncovered for 30 to 35 minutes, stirring once halfway through, until the chicken is cooked through and reaches 165°F in the center.
6. Let the dish rest for 5 minutes before serving, then spoon it over rice, noodles, or potatoes if desired.
Variations & Tips
Kid-Friendly Version: If your family prefers milder flavors, use a little less onion soup mix and serve the chicken over buttered noodles. That soft, creamy combination is often a big win for picky eaters.
Add a Vegetable: You can scatter broccoli florets, sliced mushrooms, or frozen mixed vegetables around the chicken before baking to turn it into more of a one-pan meal. Just be sure not to overcrowd the dish so the chicken still bakes properly.
Cheesier Finish: For a richer top, sprinkle a little extra Parmesan over the dish during the last 5 minutes of baking. It adds a lightly golden finish and a little more savory flavor.
Doneness Tip: Because chicken breast can dry out if overbaked, start checking a few minutes early, especially if your chicken pieces are cut small. A quick-read thermometer is the easiest way to make sure the chicken is safely cooked without going too far.
Make It a Meal: If you want a fuller casserole feel, stir the finished chicken into cooked rice or egg noodles before serving. That helps stretch the dish and makes it especially handy when you need to feed a few extra people.
