Why This Recipe Works for a Crowd

Mac and cheese is a dish nearly everyone loves, from kids to grandparents. It fills plates and pairs with almost any main dish.

This recipe makes a large batch in one 9 by 13 inch dish. The creamy sauce stays smooth even after reheating.

It is also budget-friendly. Pasta, milk and cheese stretch far, which helps when you are feeding a big group.

Best of all, most of the work happens before guests arrive. You can relax and enjoy the party while the oven finishes the job. Soon the whole kitchen fills with a rich, cheesy smell.

Ingredients You Need

The Best Cheeses to Use

Sharp cheddar gives classic flavor and a rich orange color. Pair it with a smooth melting cheese for creaminess.

Monterey Jack, Gouda and Gruyere all melt well. Gruyere adds a nutty taste, while Gouda adds a gentle smokiness if you choose smoked Gouda.

Shred cheese from a block instead of buying pre-shredded bags. Bagged cheese often contains anti-caking powder that can make the sauce grainy.

Kitchen Tools

• A large pot for the pasta
• A heavy saucepan for the cheese sauce
• A whisk and a wooden spoon
• A box grater
• A 9 by 13 inch baking dish

How to Make Baked Mac and Cheese Step by Step

1. Heat the Oven

Set the oven to 375 degrees Fahrenheit. Butter your baking dish well on all sides.

2. Cook the Pasta

Boil the macaroni in well-salted water for two minutes less than the package says. Drain it and set it aside.

The pasta will keep cooking in the oven. Undercooking it now prevents a mushy result.

3. Make the Roux

Melt 6 tablespoons of butter in a heavy saucepan over medium heat. Whisk in the flour and cook for about one minute.

4. Add the Milk

Slowly pour in the milk while whisking. Keep stirring until the sauce thickens and coats the back of a spoon, about eight minutes.

5. Melt in the Cheese

Take the pan off the heat. Stir in the mustard powder, garlic powder, salt and pepper.

Add the cheese a handful at a time, stirring until smooth. Save one cup of cheddar for the top.

6. Combine and Top

Fold the pasta into the sauce and spread it in the dish. Sprinkle the saved cheddar on top.

Melt the remaining 2 tablespoons of butter and toss with the panko. Scatter the crumbs over the cheese.

7. Bake

Bake for about 25 minutes, until bubbling and golden. Let it rest for 10 minutes so the sauce settles.

Recipe at a Glance

Make It Ahead

Holiday cooking gets busy, so making this dish ahead helps a lot. Assemble the casserole up to one day early, but skip the crumb topping.

Cover the dish tightly and refrigerate it. The pasta will soak up some sauce overnight, so add a splash of milk before baking.

On the day, add the crumbs and bake for 35 to 40 minutes, since the dish starts cold. Cover with foil if the top browns too fast.

Tasty Add-Ins and Variations

Once you have the basic recipe, it is easy to change it up.

• Stir in crispy cooked bacon or diced ham.
• Add roasted broccoli or peas for color and nutrition.
• Swap panko for crushed crackers for a buttery crunch.
• Mix in diced green chiles and pepper jack for a spicy version.
• Use a gluten-free pasta and flour blend for a gluten-free dish.

Baked or Stovetop Mac and Cheese?

Stovetop mac and cheese is quick and extra creamy. You simply stir cooked pasta into the hot sauce and serve.

Baked mac and cheese takes longer but has a golden, crunchy top. It also holds its shape better on a buffet.

For crowds, baked is usually the better choice. You can make it ahead and serve it straight from the dish.

Set Up a Mac and Cheese Bar

A mac and cheese bar is a fun idea for parties. Guests scoop a serving and add their own toppings.

Set out small bowls of bacon bits, chopped scallions, roasted broccoli, hot sauce and extra breadcrumbs. Kids and adults both love building their own bowls.

Keep the mac and cheese warm in a slow cooker. Label any toppings that contain nuts or other common allergens.

A Little Nutrition Note

Mac and cheese is a treat, but it does offer some protein and calcium from the milk and cheese. The United States Department of Agriculture (USDA) MyPlate dairy guide explains how dairy fits into a balanced diet.

To lighten it up, use low-fat milk and add vegetables like broccoli or cauliflower. Serve smaller portions next to a big salad.

Keep It Warm for Parties

Large gatherings often mean food sits out for a while. Keep mac and cheese warm in a slow cooker set to the warm setting.

Stir in a little milk every 30 minutes to keep it creamy. Cover it so the top does not dry out.

Do not leave it sitting at room temperature for more than two hours. Bacteria can grow fast in warm, dairy-rich dishes.

Store and Reheat Leftovers

Refrigerate leftovers within two hours of serving, the USDA advises. Store them in sealed containers for three to four days.

Reheat portions in the microwave with a splash of milk, stirring halfway. For a crispier top, warm the dish in a 350 degree oven, covered with foil.

The FoodSafety.gov four steps guide is a handy reminder for party food safety.

• Pasta cooked two minutes short
• Cheese shredded from a block
• Sauce thickened before cheese
• Topping added before baking
• Rested 10 minutes
• Leftovers chilled within two hours

Scale the Recipe for Your Group

One batch serves 12 to 14 people as a side. For a main dish, plan on six to eight servings.

Use this servings scaler to see how many pounds of pasta you need.

For very large groups, bake two separate dishes. They heat more evenly than one deep pan.

Make It Kid-Friendly

Kids often prefer a milder, extra creamy mac and cheese. Use mild cheddar and skip the mustard powder for picky eaters.

Bake a small portion in a separate dish without the crunchy topping. Some children like a softer texture.

Let kids help sprinkle the cheese on top before baking. They are more likely to eat food they helped make.

Common Mistakes to Avoid

Overcooked pasta is the most common problem. Always cook it two minutes short of the package time.

A grainy sauce usually means the cheese got too hot. Add cheese off the heat and stir gently.

Skipping the rest time can make the dish runny. Ten minutes lets the sauce thicken up.

A Little Mac and Cheese History

Baked macaroni and cheese has been popular in the United States for well over 200 years. Early cookbooks included versions with pasta, butter and cheese baked in the oven.

Today it is a beloved comfort food. In many Southern homes, baked mac and cheese is a must-have holiday side.

What to Serve With It

Mac and cheese pairs well with roast turkey, ham, barbecue or fried chicken. A green side, like green beans or a crisp salad, balances the rich, creamy flavor nicely.
