On the busiest weeknights, a simple oven dinner built from freezer and pantry staples can feel like a lifesaver, and this 5-ingredient oven chicken is exactly that kind of meal. Using frozen pre-cooked diced chicken keeps prep almost effortless, while a creamy sauce, a vegetable, and a crisp savory topping bake together into something cozy and satisfying with very little hands-on work. It is the kind of practical casserole-style dinner that fits real life, especially when you want comfort food without a sink full of dishes.
This chicken is hearty enough to stand on its own, but it also pairs really well with easy sides like steamed rice, buttered egg noodles, mashed potatoes, or a simple green salad. If you want to round it out for a family dinner, add roasted carrots, green beans, or warm dinner rolls to soak up the creamy sauce and crunchy topping.
5-Ingredient Oven Chicken
Servings: 4 to 6
Ingredients
1 bag (24 to 26 ounces) frozen pre-cooked diced chicken
Directions
1. Preheat the oven to 375°F. Lightly grease a metal baking sheet or a rimmed baking pan with sides so the creamy mixture stays contained while it bakes.
2. Spread the frozen pre-cooked diced chicken evenly over the baking sheet. Scatter the frozen mixed vegetables over the top.
3. In a medium bowl, stir together the condensed cream of chicken soup and sour cream until smooth. Spoon the mixture over the chicken and vegetables, then gently spread it around so everything is lightly coated.
4. Sprinkle the stuffing mix or breadcrumbs evenly over the top to create a full crumb layer.
5. Bake for 30 to 40 minutes, or until the chicken is heated through, the sauce is bubbling around the edges, and the topping is crisp and golden brown. Let it rest for 5 minutes before serving.
Variations & Tips
Add cheese: For an even cozier version, sprinkle 1 cup shredded cheddar or mozzarella under the crumb topping before baking. It melts into the sauce and makes the filling extra rich.
Swap the vegetables: Broccoli, peas, green beans, or California blend vegetables all work nicely here. This is a great clean-out-the-freezer recipe, so use what you already have.
Use a deeper pan if needed: If your baking sheet is shallow, place it on another pan to catch any drips, or use a 9-by-13-inch baking dish instead. The mixture gets bubbly as it heats.
Boost the seasoning: If you want a little more flavor, add black pepper, garlic powder, onion powder, or a pinch of dried thyme to the soup mixture. Since the chicken is pre-cooked, seasoning the sauce is the easiest way to customize the dish.
Make it meal-prep friendly: Leftovers reheat well for lunch the next day. Store portions in airtight containers in the refrigerator for up to 3 days, and reheat in the microwave or a low oven until hot.
