This 5-ingredient oven chicken is the kind of practical weeknight dinner that earns a permanent spot in your rotation. Using frozen diced chicken keeps prep minimal, and baking everything together on a metal sheet pan makes the method especially convenient when time and energy are short. The result is a savory, hearty meal with tender chicken and roasted vegetables, built from pantry-friendly ingredients and a straightforward sheet-pan technique that suits busy home cooks.
Serve this chicken with steamed rice, buttered noodles, mashed potatoes, or warm crusty bread to catch the flavorful juices. A simple green salad, roasted broccoli, or green beans round out the plate nicely, and if you want to stretch the meal further, spoon the chicken mixture into wraps, over baked potatoes, or into grain bowls with a little shredded cheese or a dollop of sour cream.
5-Ingredient Oven Chicken
Servings: 4
Ingredients
1 1/2 pounds frozen diced chicken
2 cups frozen mixed bell peppers and onions
1 packet dry Italian dressing seasoning mix
2 tablespoons olive oil
1 cup barbecue sauce
Directions
1. Preheat the oven to 425°F. Lightly oil a metal baking sheet or line it with parchment for easier cleanup.
2. Spread the frozen diced chicken and frozen peppers and onions evenly across the baking sheet. Drizzle with the olive oil and sprinkle the Italian dressing seasoning over everything.
3. Bake for 20 minutes, then remove the pan and stir well so the chicken cooks evenly and the vegetables roast rather than steam.
4. Return the pan to the oven and bake for 10 to 15 minutes more, or until the chicken is cooked through and any excess liquid has reduced. Stir in the barbecue sauce, then bake 5 minutes longer until everything is hot and glazed.
5. Serve hot straight from the pan or spoon over rice, noodles, or potatoes.
Variations & Tips
Use a thermometer: Because frozen chicken can release extra moisture as it bakes, the most reliable way to judge doneness is with an instant-read thermometer. The chicken should reach 165°F in the center before serving.
Switch the sauce: Barbecue sauce gives this dish a sweet-smoky finish, but teriyaki sauce, buffalo sauce, or honey garlic sauce also work well. If you use a sweeter sauce, add it only near the end so it does not scorch on the pan.
Add a starch to the meal: If you want a fuller one-pan dinner, serve the finished chicken over cooked rice or couscous rather than adding raw starch to the baking sheet. Frozen chicken and vegetables release enough moisture that separate cooked grains give a better texture.
Roast for better color: Spread the ingredients in as even a layer as possible and avoid overcrowding. If your pan is too full, use two pans so the chicken and vegetables roast properly and develop better browning.
