This Oven-Baked Zesty Italian Macaroni is an easy, flavorful pasta casserole that starts with uncooked elbow macaroni and cooks entirely in the oven. The pasta steams beneath a layer of foil while soaking up the bold flavor of zesty Italian dressing, mozzarella, and Parmesan. It finishes uncovered with a bubbly, golden cheese topping for a comforting dish with minimal preparation.

Oven-Baked 4-Ingredient Zesty Italian Macaroni

Ingredients

Ingredient	Quantity
Uncooked elbow macaroni	2 cups
Bottled zesty Italian dressing	1 1/2 cups
Shredded mozzarella cheese (divided)	1 1/2 cups
Grated Parmesan cheese	1/2 cup
Water (optional, if pasta looks dry)	1/2 cup

Step-by-Step Directions

1. Preheat the Oven and Prepare the Pan

Preheat your oven to 350°F (175°C). Lightly coat a 9×13-inch baking pan with cooking spray or a little oil.

2. Add the Pasta and Cheese

Spread the uncooked elbow macaroni evenly over the bottom of the prepared pan. Sprinkle 1 cup of the mozzarella and all of the Parmesan evenly over the dry pasta.

3. Pour Over the Dressing and Cover

Shake the bottle of zesty Italian dressing thoroughly, then pour it evenly across the pasta and cheese. Gently tilt the pan to help distribute the liquid. Cover the entire pan tightly with foil.

4. Bake Covered

Place the pan on the center oven rack and bake for 35 to 40 minutes, or until the macaroni is tender. If the pasta still appears dry or remains firm, pour 1/2 cup water over the top, cover the pan again, and continue baking for another 10 minutes.

5. Finish with the Remaining Cheese

Carefully remove the foil and scatter the remaining 1/2 cup mozzarella over the pasta. Return the pan to the oven and bake uncovered for 8 to 10 minutes, until the cheese has melted and the edges are lightly golden.

6. Rest and Serve

Let the macaroni bake sit for 5 to 10 minutes before serving. This brief resting time allows it to settle slightly. Serve warm and enjoy.
