Ingredients

• 2 cups bottled garlic butter sauce
• 2 cups milk
• 1 1/2 cups grated parmesan cheese, divided

How to Make Garlic Parmesan Macaroni

1. Prepare the baking dish.
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to prevent sticking.

2. Add the pasta and sauce.
Spread the uncooked elbow macaroni evenly across the bottom of the baking dish. Pour the milk and garlic butter sauce over the pasta, making sure the liquid is distributed as evenly as possible.

3. Add the parmesan.
Sprinkle 1 cup of the grated parmesan over the macaroni. Gently stir everything together so the pasta is coated and the cheese is distributed throughout the dish.

4. Cover and bake.
Cover the baking dish tightly with aluminum foil. Bake for approximately 30 minutes.

5. Finish the casserole.
Remove the foil and stir the macaroni well. Check that the pasta is absorbing the liquid evenly. Sprinkle the remaining 1/2 cup parmesan over the top.

Return the uncovered dish to the oven and bake for another 15–20 minutes, or until the macaroni is tender and the top is lightly golden.

6. Let it rest.
Allow the baked macaroni to rest for 5–10 minutes before serving. This gives the sauce time to settle and helps create a creamier consistency.

Easy Variations

Make It Extra Creamy

For an even richer baked macaroni casserole, stir in about 1/2 cup of sour cream or softened cream cheese after the first stage of baking. Continue baking until the mixture is creamy and bubbling.

Make It Kid-Friendly

If you prefer a milder cheese flavor, replace part of the parmesan with finely shredded mozzarella. The mozzarella melts beautifully and creates an extra-cheesy texture.

Add Chicken for a Complete Meal

Turn this simple side dish into a hearty dinner by adding cooked chopped chicken before baking. Rotisserie chicken is an especially convenient option.

Add Vegetables

For extra color and nutrition, mix in cooked broccoli, peas, spinach, mushrooms, or roasted vegetables.

Create a Crispy Topping

Sprinkle buttered breadcrumbs over the macaroni during the final 15 minutes of baking for a golden, crunchy topping.

What to Serve With Garlic Parmesan Macaroni

This creamy baked macaroni pairs well with:

• Roasted chicken
• Baked beef meatloaf
• Grilled or roasted beef
• Roasted vegetables
• Steamed broccoli
• Green salad
• Dinner rolls
• Green beans

For a meatless dinner, serve a generous portion with a crisp salad and roasted vegetables.

Tips for the Best Baked Macaroni

Keep it covered initially: The foil traps steam and helps the uncooked macaroni absorb the milk and sauce.

Don’t skip the resting time: Letting the casserole sit for several minutes after baking allows the sauce to thicken.

Check the pasta before the final bake: If the macaroni still looks dry or isn’t tender enough, add a small splash of milk before continuing to bake.

Spread the pasta evenly: An even layer helps the macaroni cook more consistently.

Watch the final baking stage: Once uncovered, the parmesan topping can brown quickly, so keep an eye on it during the last few minutes.

Frequently Asked Questions

Can I bake the macaroni without boiling it first?

Yes. This recipe is specifically designed to use uncooked elbow macaroni. The pasta cooks in the milk and garlic butter sauce while covered in the oven.

Can I make this macaroni ahead of time?

You can assemble the ingredients ahead of time, but for the best texture, bake it close to serving time. If preparing it in advance, make sure the pasta has enough liquid to cook properly.

Can I use another type of pasta?

Elbow macaroni works best because its size and shape allow it to cook evenly. Small pasta shapes such as small shells or ditalini may also work, but cooking time and liquid absorption can vary.

How can I make this a main dish?

Add cooked chicken, ham, ground beef, or vegetables to make the casserole more substantial.

Can I use mozzarella instead of parmesan?

Yes. Mozzarella can replace some of the parmesan for a milder, stretchier cheese topping.
