Easy 5 Ingredient Oven Baked Mac and Cheese

When you need a comforting homemade dinner but don’t feel like spending hours in the kitchen, this easy oven-baked mac and cheese is the perfect solution. Made with just five simple ingredients, this creamy no-boil macaroni and cheese goes straight from dry pasta to the oven without requiring a separate pot of boiling water.

The secret is pouring cold whole milk directly over uncooked elbow macaroni and letting the oven slowly transform everything into a rich, cheesy casserole. Butter adds extra richness, sharp cheddar delivers plenty of flavor, and the covered baking dish traps the steam needed to cook the pasta until tender.

This old-fashioned baked mac and cheese is perfect for busy weeknight dinners, family gatherings, potlucks, and cozy Sunday meals. Best of all, there’s minimal cleanup and no complicated cheese sauce to prepare on the stovetop. Just mix, bake, and enjoy!

Ingredients

• 2 cups dry elbow macaroni
• 3 cups cold whole milk
• 2 cups shredded sharp cheddar cheese, loosely packed
• 3 tablespoons unsalted butter, cut into small pieces
• 1 teaspoon kosher salt, plus more to taste

Instructions

1. Preheat the oven: Set your oven to 350°F (175°C). Lightly grease a 2–2.5-quart ceramic casserole dish with butter or nonstick cooking spray.
2. Add the dry pasta: Spread the uncooked elbow macaroni evenly across the bottom of the prepared casserole dish.
3. Season and add butter: Sprinkle the kosher salt over the pasta, then distribute the small butter pieces evenly across the surface.
4. Pour in the milk: Slowly pour the cold whole milk over the uncooked macaroni, making sure the noodles are moistened and mostly submerged. Gently press any exposed pasta into the milk.
5. Add the cheese: Sprinkle 1½ cups of shredded sharp cheddar over the pasta and milk mixture. Reserve the remaining ½ cup for the topping. Leave the ingredients layered without stirring.
6. Bake covered: Cover the casserole dish tightly with aluminum foil. Bake for 35–40 minutes, or until the macaroni is mostly tender when tested with a fork.
7. Stir until creamy: Carefully remove the foil, watching out for hot steam. Stir thoroughly from the bottom, incorporating the melted cheese, butter, and thickened milk into a creamy sauce.
8. Add the final cheese topping: Sprinkle the remaining ½ cup of cheddar evenly over the macaroni.
9. Finish baking: Return the dish to the oven uncovered for another 10–15 minutes, until the cheese is melted, bubbly, and lightly golden around the edges.
10. Rest and serve: Allow the casserole to rest for 5–10 minutes so the sauce can thicken. Serve warm and enjoy your homemade creamy baked mac and cheese!

Helpful Tips for the Best No-Boil Mac and Cheese

Shred your own cheese: Freshly shredded cheddar generally melts more smoothly than pre-shredded cheese, which often contains anti-caking ingredients.

Use the right casserole dish: A 2–2.5-quart ceramic baking dish provides enough room for the macaroni and milk to cook evenly.

Keep the dish tightly covered: Aluminum foil helps trap steam, which is essential for cooking the uncooked pasta.

Check the pasta before removing it: Baking times can vary depending on the pasta brand, casserole dish, and oven. If the macaroni is still firm, cover and bake a little longer.

Let it rest: Give the casserole a few minutes to settle after baking. This helps the cheese sauce thicken and cling to the noodles.

Easy Variations to Try

• Mild Cheddar Mac and Cheese: Replace sharp cheddar with mild cheddar for a softer, family-friendly cheese flavor.
• Extra Creamy Mac and Cheese: Add another tablespoon of butter when stirring the pasta after the first baking stage.
• Parmesan Cheddar Mac and Cheese: Mix in a handful of freshly grated Parmesan for extra savory flavor.
• Crunchy Baked Mac and Cheese: Sprinkle ½ cup of breadcrumbs mixed with a teaspoon of olive oil or melted butter over the cheese before the final bake.
• Vegetable Mac and Cheese: Stir in thawed peas or finely chopped cooked broccoli before the final baking stage.
• Chicken Mac and Cheese: Add small pieces of cooked chicken for a heartier, protein-rich dinner.
• Smoky Mac and Cheese: Add a pinch of smoked paprika and black pepper for extra flavor.

What to Serve with Baked Mac and Cheese

This creamy macaroni casserole pairs beautifully with simple side dishes that balance its rich, cheesy flavor.

• Steamed broccoli or roasted carrots.
• Fresh green salad with a light dressing.
• Garlic green beans.
• Roasted vegetables.
• Grilled or oven-baked chicken.
• Fresh fruit such as grapes, apples, or berries.

Storage and Reheating

Refrigerator: Store leftover mac and cheese in an airtight container for up to 3–4 days.

Reheating: Warm individual portions in the microwave, adding a small splash of milk to restore the creamy consistency. You can also reheat it in a covered oven-safe dish at 325°F until heated through.

Freezing: Freezing is possible, but the milk-based sauce may change texture after thawing. For the best creamy consistency, enjoy it freshly baked or refrigerated.

Frequently Asked Questions

Can I put uncooked macaroni directly into a casserole dish?

Yes! This recipe is designed to cook dry elbow macaroni directly in the casserole dish. The milk and trapped steam help soften the pasta as it bakes.

Do I need to boil the macaroni first?

No. This is a no-boil baked mac and cheese recipe. The dry pasta goes directly into the baking dish without precooking.

Why is my baked mac and cheese still watery?

It may need additional baking time or a few more minutes of resting. Make sure the foil is tightly sealed during the first baking stage to retain steam.

Can I use a different type of cheese?

Absolutely. Mild cheddar, mozzarella, Monterey Jack, and Parmesan can all be used to create different flavors and textures.

Can I prepare this recipe ahead of time?

For the best results, bake it immediately after assembling. Leaving uncooked pasta sitting in milk for an extended period can affect how evenly it cooks.
