Picture your perfect holiday table, glowing with warmth and filled with the most incredible aromas. At the center of it all, nestled between the roast and the greens, is a bubbling, golden-brown casserole of the richest, creamiest macaroni and cheese. This isn’t just any side dish; it’s a showstopper. My ultimate Christmas mac and cheese recipe is designed to be that star, delivering pure comfort and festive cheer. It’s reliable, impressive, and includes make-ahead tips to save you time, promising the cheesiest, most flavorful bake with a special holiday twist and a perfectly crunchy topping.

Why You’ll Love This Festive Mac and Cheese

What elevates this from a simple side to a true Christmas masterpiece is a subtle, festive twist. We infuse the classic béchamel sauce with finely minced fresh rosemary and a delicate pinch of freshly grated nutmeg. These warm, aromatic spices create a truly special holiday recipe.

Perfectly Festive Flavor. The rosemary is a classic holiday herb that beautifully cuts through the richness of the cheese, while nutmeg enhances the creamy dairy notes, adding a layer of warmth and sophistication. A simple garnish of fresh cranberries and a rosemary sprig adds a pop of red and green, making it look as festive as it tastes.

Outrageously Creamy & Cheesy. I use a perfect blend of sharp cheddar for that classic, tangy flavor and nutty Gruyère for its superior melting quality. This combination creates an ultra-creamy, ooey-gooey homemade cheese sauce that coats every single noodle.

Make-Ahead Friendly. The holidays are busy enough! A huge benefit of this recipe is that you can assemble it a day or two in advance. This saves precious time and oven space on Christmas Day, making your celebration smoother and more enjoyable.

Foolproof & Reliable. My detailed instructions and pro tips will help you avoid common pitfalls like a grainy sauce or mushy pasta. By following this guide, you can confidently create a perfect baked mac and cheese every single time.

Ingredients Needed

• 16 oz elbow macaroni, cooked ((or other tubular pasta))
• 1 tbsp extra virgin olive oil
• 6 tbsp unsalted butter
• 1/3 cup all purpose flour
• 3 cups whole milk
• 1 cup heavy whipping cream
• 4 cups sharp cheddar cheese (shredded)
• 2 cups Gruyere cheese (shredded)
• salt and pepper to taste
• 1 1/2 cups panko crumbs
• 4 tbsp butter (melted)
• 1/2 cup Parmesan cheese (shredded)
• 1/4 tsp smoked paprika ((or regular paprika))

Ingredient Notes & Substitutions

The Cheeses: The combination of sharp cheddar and Gruyère is magical. Cheddar provides that bold, classic mac and cheese flavor, while Gruyère brings a nutty complexity and an incredible, silky melt. For the creamiest sauce, you must shred your own cheese from a block. Pre-shredded cheeses contain anti-caking starches that can make your sauce grainy. If needed, you could substitute Jarlsberg or Monterey Jack for the Gruyère.

The Pasta: Sturdy pasta shapes with ridges or tubes are best for catching all that glorious cheese sauce. Elbow macaroni is classic, but cavatappi, shells, or penne are also fantastic choices.

Milk & Cream: This is a holiday dish, so now is the time for full-fat dairy! The combination of whole milk and heavy cream is essential for creating a rich, stable, and luxuriously creamy béchamel sauce. I don’t recommend using low-fat milk.

How to Make Christmas Mac and Cheese

This recipe is straightforward and comes together in a few distinct phases. Follow these steps for perfect results.

1. Prepare the Pasta and Topping

1. Preheat your oven to 350°F (175°C). Lightly grease a large 3 or 4-quart baking dish.
2. Cook the pasta according to package directions, but pull it from the water one minute before it reaches al dente. This is crucial to prevent it from getting mushy after baking in the oven. Drain the pasta well.
3. In a large bowl, drizzle the cooked pasta with olive oil and toss gently to coat. This prevents the noodles from sticking together while you prepare the sauce. Set it aside.
4. In a separate small bowl, prepare the topping. Combine the panko crumbs, shredded Parmesan cheese, melted butter, and smoked paprika. Mix until the crumbs are evenly moistened and set aside.

2. Make the Creamy Béchamel Cheese Sauce

1. In a large Dutch oven or heavy-bottomed pot, melt 6 tablespoons of unsalted butter over medium heat.
2. Whisk in the all-purpose flour to create the roux. Continue whisking constantly for about one minute until it’s bubbly and golden. This step cooks out the raw flour taste.
3. Gradually pour in the cold milk and heavy cream while whisking constantly. Adding the cold liquid slowly to the hot roux is the secret to a perfectly smooth, lump-free sauce.
4. Continue cooking, whisking frequently, until the sauce thickens enough to coat the back of a spoon, about 5-7 minutes. Once it begins to bubble at the surface, continue cooking for 2 more minutes.
5. Remove the pot from the heat. This is a very important step! Add your minced rosemary and nutmeg here, then season with salt and pepper. Add the shredded cheddar and Gruyère cheeses in batches, whisking until each addition is completely melted and the sauce is velvety smooth before adding the next.

3. Assemble and Bake

1. Pour the cooked pasta into the pot with the finished cheese sauce. Stir gently until every noodle is completely coated in creamy goodness.
2. Pour half of the mac and cheese mixture into your prepared baking dish. Sprinkle 2 cups of the remaining shredded cheese over this layer. Top with the rest of the mac and cheese.
3. Sprinkle the prepared panko topping evenly over the entire casserole.
4. Bake, uncovered, for about 30 minutes, or until the sauce is bubbly around the edges and the topping is a beautiful golden brown. Let it rest for a few minutes before serving.

Holiday Prep: Your Make-Ahead & Reheating Guide

Planning is key for a stress-free holiday. This Christmas side dish is perfectly suited for preparing in advance.

How to Make Mac and Cheese Ahead of Time

You can fully assemble this casserole 1 to 2 days before you plan to bake it.

1. Follow the recipe through the assembly steps, layering the mac and cheese in the baking dish.
2. Do not add the panko topping. The topping should always be added just before baking to ensure it stays crispy.
3. Cover the dish tightly with foil or plastic wrap and refrigerate for up to 2 days.
4. When ready to bake, remove the dish from the fridge and let it sit at room temperature for about 30 minutes. Sprinkle the fresh panko topping over the top and bake as directed, adding 10-15 minutes to the total baking time since it’s starting from cold.

The Secret to Reheating Leftovers Creamily

Leftover mac and cheese can be just as good as the first day if you reheat it properly. Avoid the microwave, which can make the sauce oily and separated.

• Oven Method (Best): Place leftovers in a small baking dish. For every cup of mac and cheese, stir in a splash of milk (about 1-2 tablespoons) to restore moisture. Cover the dish with foil and bake at 350°F for about 20 minutes, or until heated through.
• Stovetop Method (Quick): For smaller portions, reheat in a saucepan over low heat. Add a splash of milk and stir frequently until it’s hot and creamy again.

Pro Tips & Troubleshooting

Here are a few key tips from my kitchen to yours, ensuring this holiday recipe turns out perfectly every time.

Pro Tips for the Best Baked Mac and Cheese

• Shred Your Own Cheese: This is my number one rule. Pre-shredded cheese contains starches that prevent a silky-smooth sauce. A few minutes with a block and a box grater is worth the effort.
• Don’t Overcook the Pasta: Remember, the pasta will continue to cook in the oven. Undercooking it by one minute ensures it has the perfect bite after baking.
• Use Cold Dairy in a Hot Roux: This temperature difference is key to creating a lump-free béchamel sauce. Whisk constantly as you slowly pour it in. For another dish with a similarly rich and creamy sauce, try our smothered chicken and rice.
• Use Room Temperature Cheese: Let your shredded cheese sit out for a few minutes before adding it to the sauce. Adding very cold cheese to a very hot sauce can cause it to seize and become oily.
• Taste Your Sauce: Before adding the pasta, give your cheese sauce a taste. Adjust the salt and pepper as needed. Cheese varies in saltiness, so tasting is crucial.

Troubleshooting: Fixing Common Mistakes

Why is my sauce grainy?
This is almost always caused by using pre-shredded cheese or overheating the sauce after the cheese was added. To fix it, use block cheese and always add it off the heat.

Why is my sauce oily or broken?
The sauce’s emulsion has broken. This can happen if the cheese has a high oil content or if it was heated too quickly. Let the sauce cool slightly and then whisk vigorously to see if you can bring it back together.

Why is my topping soggy?
This usually happens if the butter-to-panko ratio is off or if the casserole was covered during baking. Ensure the crumbs are evenly coated with butter and always bake this dish uncovered to get a crispy, golden crust.

Serving, Storing, and Scaling

This dish is ready for your holiday table! Here’s how to serve, store, and scale it.

What to Serve with Christmas Mac and Cheese

This creamy, cheesy casserole is the ultimate comfort food and a perfect Christmas side dish. It pairs beautifully with holiday mains like a roasted turkey, glazed ham, or beef tenderloin. To balance its richness, I love serving it alongside roasted green beans, a bright green salad, or Brussels sprouts. For a final festive touch, garnish the finished dish with a few fresh cranberries and a sprig of rosemary just before serving.

Storage Instructions

Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. For best results, follow the reheating instructions provided in the dedicated section above. While you can freeze this mac and cheese, be aware that dairy-based sauces can sometimes change texture upon thawing. If freezing, place it in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating using the oven method.

Scaling This Recipe for a Crowd

Planning a large holiday gathering? This recipe can easily be doubled. Simply double all the ingredients and assemble it in a larger baking dish, such as a 9×13 inch pan or equivalent.

Frequently Asked Questions

1. What are the best cheeses for a Christmas mac and cheese?

   A mix of a great melting cheese and a great flavor cheese is key. We love sharp cheddar for its classic tangy flavor and Gruyère for its nutty complexity and supreme creaminess. They create a perfectly balanced and smooth homemade cheese sauce.

2. How do you make a cheese sauce that isn’t grainy?

   The secret is to shred your own cheese from a block. Pre-shredded cheeses contain anti-caking agents like potato starch that prevent the cheese from melting smoothly. Also, be sure to remove the sauce from the heat before you whisk in the cheese.

3. Can this Christmas mac and cheese be made ahead of time?

   Yes, absolutely! You can assemble the entire casserole up to two days in advance, but leave off the panko topping. Cover and refrigerate, then add the topping just before baking. Check our full make-ahead guide above for detailed instructions.

4. What is the secret to a perfectly crunchy, golden-brown topping?

   Use panko breadcrumbs! They are lighter and crispier than regular breadcrumbs. Tossing them with melted butter and Parmesan cheese before sprinkling them on top ensures they toast evenly and become irresistibly crunchy. Always bake uncovered.

5. How do I store and reheat leftover baked mac and cheese?

   Store leftovers in an airtight container in the refrigerator for up to 4 days. For the best reheating results that restore creaminess, use the oven method: place in a baking dish with a splash of milk, cover with foil, and bake at 350°F until warm.

6. Can I add bacon to this recipe?

   Absolutely! Bacon is a delicious addition. For a savory, smoky flavor, stir about a pound of cooked, crumbled bacon into the pasta and cheese sauce mixture before pouring it into the baking dish.
