Side Dishes
This baked mac and cheese recipe for large group is the ultimate crowd-pleaser—crispy golden edges, gooey pulls, and enough servings to feed a crowd without the stress. I perfected it after years of hosting holiday dinners in my Boston triple-decker, where the kitchen was barely bigger than the stove.
The secret? A foolproof technique that scales beautifully while keeping every bite restaurant-quality.
With just 10 ingredients and one 9x13-inch baking dish, this recipe handles 12-15 servings effortlessly. The key is a two-step cheese sauce—first melting sharp cheddar and Gruyère, then adding cream cheese for that signature velvety texture.
A buttery breadcrumb topping creates that crispy crust everyone loves, while the pasta absorbs the sauce perfectly during baking.
What sets this apart is the make-ahead flexibility: prep the dish the night before, refrigerate, and bake straight from the fridge for foolproof results. The sauce won’t separate, the breadcrumbs stay crispy, and the gooey pulls remain intact.
Perfect for game days, potlucks, or holiday gatherings where you’d rather spend time with guests than stressing in the kitchen.
For extra flavor, stir in cooked bacon, steamed broccoli, or a dash of hot sauce before baking. And don’t worry about leftovers—this mac and cheese reheats beautifully, making it ideal for meal prep too. Let’s get cooking!
Ingredients for baked mac and cheese recipe for large group
Ten simple ingredients for a crowd-sized feast with crispy edges and gooey perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 2 ½ lbs | Dry, medium or jumbo size |
| Sharp White Cheddar Cheese 🧀 | 2 ½ lbs | Block, freshly grated |
| Gruyère Cheese 🧀 | 1 ½ lbs | Shredded, nutty flavor |
| Cream Cheese 🧈 | 16 oz | Full-fat, room temperature |
| Heavy Cream 🥛 | 2 cups | Whole milk, 36% fat |
| Butter 🧈 | ¾ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | ½ cup | For thickening sauce |
| Panko Breadcrumbs 🍞 | 2 cups | Japanese-style, toasted |
| Dijon Mustard 🍯 | 1 tbsp | For depth of flavor |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Salt 🧂 | 3 tsp | Diamond Crystal kosher |
| Black Pepper 🌶️ | 1 tsp | Freshly cracked |
The cheeses are non-negotiable here. Sharp white cheddar delivers that classic tang, while Gruyère adds nutty depth—both must be freshly grated for texture. I source mine from Whole Foods or specialty cheese shops where they block-grate it on-site. For the cream cheese, Philadelphia brand is my go-to, but any full-fat works. The elbow macaroni should be medium or jumbo size to hold up to the sauce without turning mushy—Barilla or De Cecco are my pantry staples. Pro tip: toast the breadcrumbs in a dry pan for 3-4 minutes before using them—they'll stay extra crispy even after baking.
No heavy cream? Full-fat Greek yogurt thinned with milk works in a pinch, though the texture will be slightly lighter. Substituting cheddar for Monterey Jack makes it milder for kids, but lose the Gruyère if you want to keep it authentic. The Dijon mustard adds complexity—Maille brand is ideal, but any good-quality one will do. For extra flavor without extra ingredients, smoked paprika at 1/2 teaspoon can be stirred into the sauce. And if you're prepping ahead, the sauce can be made 24 hours in advance and stored in the fridge until ready to assemble with the pasta.
This dish is a make-ahead dream. Assemble the entire casserole in a 9x13-inch baking dish and refrigerate overnight—it bakes beautifully straight from the fridge. For serving, let it rest 5 minutes after baking so the cheese sets slightly. Leftovers reheat well in the oven at 350°F for 15-20 minutes, covered with foil. Store any extras in the fridge for up to 5 days, or freeze portions for up to 3 months. The breadcrumb topping stays crispy even after reheating, but if you're worried, sprinkle fresh breadcrumbs on top before serving.
Why You'll Love This Recipe
- No-Fuss Crowd Feeder: I swear by this for gatherings—just boil the pasta, mix the cheeses (sharp cheddar + Gruyère for that nutty kick) with cream cheese and heavy cream, fold it all together, and bake. No fancy techniques, no stress, and it disappears faster than my willpower on a Sunday afternoon.
- Melty Magic Combo: That blend of sharp cheddar and Gruyère? Chef’s kiss. The Gruyère adds this rich, almost buttery depth, while the cheddar keeps it tangy—plus the cream cheese makes it impossibly creamy without being heavy. Honestly, the first bite makes me question why I’ve ever eaten store-bought.
- Potluck or Party: This is my secret weapon for potlucks, game days, or even a lazy Sunday brunch. Serve it as a side, a main, or even in muffins—just portion it differently. Between us, I’ve brought it to holiday dinners and had people ask for the recipe before they even tasted mine.
Step-by-step instructions for baked mac and cheese
This method delivers a crowd-pleasing mac and cheese with a golden crust and melt-in-your-mouth texture.
Cook the Elbow Macaroni to Perfect Al Dente
Bring a large stockpot to a rolling boil and add the 2.5 lbs elbow macaroni. Cook until 1 minute before the package instructions call for al dente—this ensures it finishes cooking in the oven. Drain immediately and transfer to a large mixing bowl. The pasta should retain some surface starch, which helps bind the cheese sauce later.
While the pasta cooks, I like to add 1 tablespoon of the 3 teaspoons salt directly to the boiling water. This enhances flavor penetration during cooking. After draining, give the pasta a quick rinse under cold water to stop the cooking process completely. Shake off any excess water, then return it to the mixing bowl.
Prepare the Ultra-Creamy Cheese Sauce
In a separate large bowl, combine the 2.5 lbs sharp white cheddar cheese, 1.5 lbs gruyère cheese, 16 oz cream cheese, and 2 cups heavy cream. Microwave in 30-second intervals, stirring vigorously between each, until the mixture reaches 160°F—just until the cream cheese melts completely. This temperature ensures smoothness without curdling.
In a medium saucepan, melt the 0.75 cup butter over medium heat. Whisk in the 0.5 cup all-purpose flour and cook for 1-2 minutes, stirring constantly, until the mixture forms a smooth roux. Slowly pour in the melted cheese mixture while whisking vigorously to prevent lumps. Add the 1 tablespoon Dijon mustard and 1 teaspoon garlic powder, then cook for 2-3 minutes until the sauce thickens to a pudding-like consistency.
Combine Pasta and Sauce
Pour the hot cheese sauce over the cooked macaroni in the mixing bowl. Add the remaining 2 teaspoons salt and 1 teaspoon black pepper, then fold everything together using a spatula or wooden spoon. The mixture should be thick and cohesive, with no dry pasta pockets. If the sauce is too thick, add 1-2 tablespoons of reserved pasta water to loosen it to a spreadable consistency.
Transfer the macaroni mixture to a 9x13-inch baking dish, spreading it evenly into a single layer. Press down gently to compact the pasta and ensure even baking. This step prevents uneven cooking and creates a smooth surface for the crispy topping.
Create the Crispy Breadcrumb Topping
In a small bowl, combine the 2 cups panko breadcrumbs with the remaining 1 teaspoon garlic powder. Spread the mixture evenly over the top of the macaroni, pressing down lightly to adhere. This topping is what delivers that coveted crispy crust—don't skip pressing it down.
Bake at 375°F for 25-30 minutes, until the top is deep golden brown and the edges bubble slightly. The internal temperature should reach 165°F when measured in the center. If the top browns too quickly, tent loosely with aluminum foil to prevent burning while allowing the center to finish cooking.
Rest and Serve for Maximum Gooeyness
Remove the baking dish from the oven and let it rest for 10 minutes before serving. This resting period allows the cheese to set slightly, making it easier to slice and serve without losing its creamy texture. The dish should be hot and bubbly, with a crispy, golden-brown crust that contrasts perfectly with the gooey interior.
Slice into 15 equal portions (about 1.5 cups each) and serve immediately. The contrast between the crispy topping and the melt-in-your-mouth cheese filling makes this mac and cheese a guaranteed crowd-pleaser for any gathering. Leftovers can be refrigerated for up to 3 days or frozen for 2 months.
Pro Tips For Making Baked Mac And Cheese Recipe For Large Group
- PASTEURIZE THE CREAM: Heat the heavy cream until it’s steaming but not boiling—just until tiny bubbles form around the edges—before mixing it into the cheese. This prevents clumping and gives the sauce a silky texture instead of that grainy, curdled mess you get when you dump cold cream into hot cheese. I learned this the hard way after making a batch that looked like cottage cheese.
- GRATE GRUYÈRE FINE: Use the small holes of a box grater for the Gruyère—no need for food processor precision. Big chunks won’t melt smoothly, and you’ll end up with a lumpy, chewy texture in the middle of your casserole. My grandmother swore by this, and she was right: the cheese should dissolve like butter, not like sand.
- DRAIN MACARONI WELL: Dump the cooked pasta into a colander, give it a quick rinse under cold water, then shake it dry in the colander for 30 seconds. The starch clinging to the noodles will make your sauce gluey and watery, especially when baking. I skip this when I’m lazy, but the dish is noticeably better when I don’t—trust me.
- BAKE COVERED FIRST: Start the mac and cheese in the oven covered with foil for the first 20 minutes at 375°F (190°C). This lets the cheese melt evenly without forming a crust too soon—then uncover for the last 10 minutes to get that golden top. After burning three batches, I finally figured out that patience here means no sad, pale casserole.
Common mistakes when making this dish
Overcooking the Pasta
I've made this mistake more times than I'd admit—cooking the elbow macaroni until it's mushy. The key is stopping 1 minute before the package calls for al dente, then finishing in the oven.
Overcooked pasta absorbs too much sauce and turns into a gluey mess. To avoid this, test one piece by biting into it—it should have a slight bite in the center. 🍝
Skipping the Roux
The roux is what transforms this from a basic cheese sauce to a silky, velvety masterpiece. Without it, your sauce will be thin and watery.
Uneven Baking
If your mac and cheese comes out with some areas undercooked and others burnt, you likely didn't spread the mixture evenly in the baking dish. Press down firmly when transferring the pasta mixture to create an even surface. Also, rotate the dish halfway through baking if your oven has hot spots. A 9x13-inch baking dish works best for even heat distribution.
Cheese Separation
Nothing ruins a good mac and cheese like a sauce that separates into greasy pools. To prevent this, melt the cheeses gently in 30-second microwave intervals while stirring vigorously.
Never microwave on high, and always bring the mixture to 160°F—no higher. Adding the cream cheese to the warm sauce (not melted) also helps stabilize the emulsion.
Breadcrumb Topping Issues
If your topping stays soggy instead of crispy, you likely didn't press it down firmly enough or didn't toast the panko beforehand. For extra insurance, I like to sprinkle the breadcrumbs on a dry skillet and toast them for 3-4 minutes before using.
Pressing down firmly ensures they adhere to the sauce and stay crispy throughout baking.
Overmixing the Sauce
Once you combine the pasta and sauce, resist the urge to stir vigorously. Overmixing can break down the pasta and make the final texture grainy. Instead, gently fold with a spatula or wooden spoon until just combined.
The sauce should coat the pasta evenly without creating lumps. If it's too thick, add 1-2 tablespoons of reserved pasta water to loosen it slightly.

Frequently asked questions
Can I use this recipe for a smaller group?
Scale down all ingredients proportionally—use 1 lb elbow macaroni, 1 lb sharp cheddar, and 0.75 lbs Gruyère for about 6 servings. The baking time remains the same (25-30 minutes), but use an 8x8-inch baking dish instead. The crispy topping ratio stays the same too.
How do I keep the breadcrumb topping extra crispy?
Toast the panko breadcrumbs in a dry skillet over medium heat for 3-4 minutes until golden before adding them to the dish. Press them firmly onto the sauce and bake at 375°F—the high heat ensures they stay crispy. For serving, sprinkle extra toasted breadcrumbs on top right before eating.
What's the best way to reheat leftovers?
For best results, cover the dish with foil and reheat at 350°F for 15-20 minutes until bubbly. If using the microwave, cover with a damp paper towel and heat in 30-second intervals, stirring between each. The breadcrumb topping may soften slightly but will crisp up again under the broiler for 1-2 minutes if needed.
Can I add other ingredients like bacon or veggies?
Yes! Stir in cooked bacon, steamed broccoli, or sautéed mushrooms before baking. For veggies, add them to the pasta while cooking to ensure they're tender. Keep portions small—1 cup total of add-ins won't overpower the dish. For extra flavor, try 1/2 teaspoon smoked paprika or a pinch of cayenne pepper.
Why did my cheese sauce separate?
This usually happens when the cheese mixture gets too hot too fast. Always melt cheeses in 30-second microwave intervals while stirring vigorously, and never exceed 160°F. Add cream cheese to the warm sauce (not melted) to stabilize the emulsion. If separation occurs, whisk in 1 tablespoon of pasta water to recombine.
