This 4-ingredient oven chicken is the kind of practical weeknight dinner that earns a regular place in the rotation: minimal prep, easy cleanup, and plenty of flavor from a short list of pantry-friendly ingredients. Using diced chicken breast helps everything cook quickly and evenly on a baking sheet, and the method is flexible enough to suit busy schedules while still delivering a dish that feels hearty and satisfying.
Serve this baked chicken over steamed rice, buttered noodles, or mashed potatoes to catch the flavorful juices, and add a simple green vegetable such as roasted broccoli, green beans, or a crisp salad on the side. It also works well tucked into warm wraps, spooned over cauliflower rice, or paired with dinner rolls for an easy, family-style meal.
4-Ingredient Oven Chicken
Servings: 4
Ingredients
1 1/2 pounds diced raw chicken breast
Directions
1. Preheat the oven to 400°F and lightly oil a large rimmed baking sheet or line it with parchment for easier cleanup.
2. Spread the diced chicken breast and halved baby potatoes on the baking sheet. Drizzle with the olive oil, then sprinkle the onion soup mix evenly over everything. Toss directly on the pan until the chicken and potatoes are well coated, then spread into a single layer.
3. Bake for 25 to 30 minutes, stirring once about halfway through, until the chicken is cooked through and the potatoes are tender and lightly browned at the edges.
4. Let the pan rest for 2 to 3 minutes, then serve hot, spooning any pan juices over the chicken and potatoes.
Variations & Tips
Add a vegetable: Broccoli florets, green beans, or bell pepper strips can be added for a more complete sheet pan dinner. Choose quick-cooking vegetables and add them for the last 12 to 15 minutes so they stay tender rather than overcook.
Use even-sized pieces: Cut the chicken into uniform bite-size pieces so it cooks at the same rate. If some pieces are much smaller than others, they can dry out before the rest of the pan is done.
Check doneness carefully: Chicken breast is lean, so pull the pan once the chicken reaches 165°F in the thickest pieces. If your potatoes need a little longer, you can remove the chicken first and return the potatoes to the oven for a few extra minutes.
Change the starch: If you do not have baby potatoes, try cubed sweet potatoes or thick slices of carrots for a slightly different flavor profile. Just keep the pieces fairly small so they roast in the same amount of time as the chicken.
