This 4-ingredient oven chicken is the kind of practical weeknight casserole that earns a regular place in the dinner rotation. Using frozen chicken nuggets as the shortcut base keeps prep especially simple, while a few pantry staples turn them into a saucy, baked main dish that feels a little more substantial than plain nuggets on a sheet pan. It is a great option for busy evenings, casual family suppers, or anytime you want a comforting meal with very little measuring, chopping, or cleanup.

Serve this saucy chicken over white rice, buttered egg noodles, or mashed potatoes to catch every bit of the sauce. A simple green salad, steamed green beans, roasted broccoli, or glazed carrots round it out nicely, and if you want to lean into the kid-friendly appeal, a side of corn or garlic bread works especially well.

Ingredients

1 bag (24 to 28 ounces) frozen chicken nuggets

1 cup ketchup or chili sauce
1/2 cup brown sugar, packed
1/4 cup Italian dressing

Directions

1. Preheat the oven to 375°F and lightly grease a 9x13-inch glass baking dish if desired for easier cleanup.

2. Spread the frozen chicken nuggets in the baking dish in an even layer.

3. In a medium bowl, stir together the ketchup or chili sauce, brown sugar, and Italian dressing until smooth and well combined.

4. Pour the sauce evenly over the nuggets and gently turn or nudge them so they are well coated.

5. Bake uncovered for 30 to 40 minutes, stirring once halfway through, until the nuggets are heated through and the sauce is bubbly and slightly thickened.

6. Serve hot on its own or spooned over rice, noodles, or mashed potatoes.

Variations & Tips

Sweeter sauce: If you want a more classic sweet-and-tangy flavor, use chili sauce instead of ketchup. It gives the finished dish a deeper tomato flavor and a little extra zip without making it spicy.

Easy add-ins: Stir in sliced bell peppers, a handful of frozen onions and peppers, or even a drained can of pineapple chunks before baking if you would like to stretch the dish and give it more of a sweet-and-sour character.

Keep some texture: Because the nuggets bake in sauce, they will be softer than oven-crisp nuggets served plain. For a little more texture, bake the nuggets for about 10 minutes first, then add the sauce and continue baking until hot and bubbly.

Make it a full meal: For a heartier casserole-style dinner, spoon the baked chicken over cooked rice in individual bowls, or serve it with roasted vegetables to balance the sweetness of the sauce.
