Ingredients for baked mac and cheese recipe for 12
Twelve servings of cheesy perfection—where crispy meets gooey in one legendary crowd-pleaser.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 2 ½ lbs | Medium or jumbo size preferred |
| Sharp White Cheddar Cheese 🧀 | 2 ½ cups | Shredded, block preferred |
| Gruyère Cheese 🧀 | 1 ½ cups | Shredded, aged 12+ months |
| Cream Cheese 🧈 | 12 oz | Full-fat, room temperature |
| Heavy Whipping Cream 🥛 | 1 ½ cups | Full-fat, cold |
| Whole Milk 🥛 | 1 ½ cups | Room temperature |
| Butter 🧈 | ¾ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | ¼ cup | For thickening |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tbsp | Adjust to taste |
| Freshly Ground Black Pepper 🌶️ | 1 tbsp | Freshly cracked |
| Panko Breadcrumbs 🍞 | 1 ½ cups | For crispy topping |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For breadcrumb mix |
| Garlic Powder 🧄 | 1 tbsp | For seasoning |
| Mustard Powder 🌶️ | 1 tsp | For depth of flavor |
The cheese trio is non-negotiable. Sharp white cheddar brings the tang, aged Gruyère adds nutty depth, and cream cheese ensures that velvety texture. I source my Gruyère from specialty cheese shops—Murray's Cheese or Di Bruno Bros carry excellent aged wheels. For the cheddar, block over pre-shredded every time; the pre-shredded kind has anti-caking agents that make the sauce grainy. The cream cheese should be full-fat and room temperature when mixed—cold lumps ruin the sauce. If you're feeding a crowd, buy two 8-ounce packages and grate your own cheddar and Gruyère for maximum freshness.
No sharp cheddar? Extra-sharp white cheddar works in a pinch, though it's slightly milder. Gruyère unavailable? Comté or Emmental are solid swaps, but reduce to 1 cup since they're milder. Substituting cream cheese? Equal parts ricotta and cream cheese lightens the texture slightly. The flour is for thickening—all-purpose works fine, but if you're gluten-free, use a 1:1 GF blend. For the breadcrumb topping, panko is essential—it stays crispy while regular breadcrumbs turn soggy. If you're watching calories, reduce the olive oil to 2 tablespoons and add an extra tablespoon of garlic powder for flavor.
Prep ahead for maximum convenience. Cook the pasta al dente and toss it with a little olive oil to prevent sticking—this keeps it from absorbing too much cheese sauce during baking. Store the unbaked casserole in the fridge for up to 24 hours; it actually tastes better the next day as the flavors meld. For serving, transfer directly from the oven to a large platter to maintain that crispy crust. Leftovers reheat beautifully in the oven at 350°F until bubbly, about 15-20 minutes. Portion into individual containers for easy grab-and-go lunches—this recipe makes enough for 3-4 lunches after the main meal.
Why You'll Love This Recipe
- One-Pot Magic: That’s right—just one big pot for the pasta, one bowl for the cheese sauce, and boom, it’s all in a baking dish. No fussing with separate pans or messy stovetop transfers, and honestly? That crispy top layer happens without extra effort. My kids think it’s fancy because it looks like a restaurant dish, but I’m just lazy enough to love it.
- Triple-Cheese Bliss: Sharp white cheddar for that tangy punch, Gruyère for nutty depth, and cream cheese to tie it all together like a creamy hug. The heavy cream keeps it luxuriously smooth, but the real win? That moment when the first bite hits—salty, rich, and just melty enough. Between us, I’ve tried cheaper cheeses, and this combo is worth every penny.
- Party-Proof Perfection: Serve it at a potluck, a game day, or even a last-minute dinner when your in-laws show up unannounced. It’s the kind of dish that disappears fast but leaves everyone begging for seconds. I’ve made this for book club nights, tailgates, and even a very casual birthday dinner—no one ever complains, and that’s saying something.
- Leftovers That Don’t Suck: Most baked mac and cheese turns into a sad, gluey mess the next day. Not this one. The Gruyère keeps it from getting grainy, and reheating? Just pop it in the oven for 10 minutes—crispy top, creamy inside, like it’s fresh. I meal prep this all the time because it’s my secret weapon for lazy Wednesdays, and yes, even on a Tuesday night.
Step-by-step instructions for baked mac and cheese
Here's how to create a crowd-pleasing mac and cheese with a perfect crispy top and gooey interior.
Cook the Elbow Macaroni to Al Dente Perfection
Bring a large pot of water to a rolling boil and add the 2.5 lbs elbow macaroni. I use medium or jumbo size for better texture. Cook until 1 minute before the package instructions specify for al dente—this ensures the pasta finishes cooking in the oven without becoming mushy.
Drain the pasta in a colander, but don't rinse it. The residual starch helps create a creamier sauce later. I like to give the hot pasta a quick shake to separate the strands before transferring it to a large mixing bowl.
Prepare the Ultra-Creamy Cheese Sauce
In the same pot you cooked the pasta, melt the 0.75 cup butter over medium heat. Once melted, whisk in the 0.25 cup all-purpose flour and cook for 1-2 minutes until the mixture forms a smooth paste and smells nutty. This is your roux foundation.
Slowly pour in the 1.5 cups heavy whipping cream and 1.5 cups whole milk while whisking constantly. Let the mixture simmer for 3-4 minutes until it thickens slightly. Remove from heat and stir in the 12 oz cream cheese until completely melted and smooth.
Combine Cheeses and Seasonings
Add the 2.5 cups sharp white cheddar cheese and 1.5 cups gruyère cheese to the sauce. Stir over low heat for 2-3 minutes until the cheeses are fully melted and the mixture is silky smooth. If the sauce looks too thick, add 1-2 tablespoons of the pasta water to loosen it.
Season generously with 1.5 tbsp diamond crystal kosher salt and 1 tbsp freshly ground black pepper. Add the 1 tbsp garlic powder and 1 tsp mustard powder for depth of flavor. The mustard powder adds a subtle tang that balances the richness of the cheeses.
Assemble and Bake for Maximum Gooeyness
Transfer the cooked macaroni to a large baking dish (I use a 9x13-inch dish for this quantity). Pour the cheese sauce over the pasta, stirring gently to combine. The mixture should be thick but still pourable.
Spread the macaroni evenly in the dish. For extra insurance against a dry top, sprinkle half of the 1.5 cups panko breadcrumbs evenly over the surface. Bake uncovered at 375°F for 20 minutes. This initial baking allows the flavors to meld and the sauce to set slightly.
Create the Crispy Topping and Finish
Remove the dish from the oven and stir the macaroni once to distribute any sauce that may have settled at the bottom. In a small bowl, mix the remaining 0.75 cup panko breadcrumbs with the 0.25 cup extra-virgin olive oil. Sprinkle this mixture evenly over the top of the macaroni.
Return to the oven and bake for an additional 10-12 minutes until the top is deep golden brown and crispy. The edges should be bubbling and the center should still be slightly jiggly—this indicates perfect doneness. Let it rest for 5 minutes before serving to allow the top to set slightly.
Pro Tips For Making Baked Mac And Cheese Recipe For 12
- Pre-Cook Macaroni Al Dente: DESCRIPTION: Undercooked pasta turns mushy when baked—overcooked turns to glue. Boil elbows in salted water until they’re just firm to the bite (about 1 minute less than package instructions), then drain and rinse with cold water. The starch clinging to them is what makes the sauce cling, but soggy pasta ruins everything.
- Shred Cheese Like a Pro: DESCRIPTION: Skip the food processor—it turns cheese into paste. Use a box grater with the largest holes and shred fresh (not pre-shredded, which has anti-caking agents). For Gruyère, pulse it briefly in a food processor first to break up clumps, but finish by hand. The texture difference is night and day.
- Don’t Rush the Cream: DESCRIPTION: Warm the heavy cream and cream cheese together slowly over low heat—never microwave. Lumps in the sauce mean grainy mac and cheese. Stir constantly until it’s smooth, then remove from heat before adding to the pasta. Patience here keeps the sauce silky.
- Bake Low and Slow: DESCRIPTION: After baking at 375°F for 20 minutes, crank the heat to 425°F for the last 5–7 minutes. This gives you a crispy top without burning the cheese underneath. Cover with foil halfway if the edges brown too fast—just uncover for the final minutes to get that golden crust.
Serving suggestions for leftovers
Crispy Top Secrets
For that golden, shatteringly crispy crust, I swear by mixing panko breadcrumbs with extra-virgin olive oil right before the final bake.
Use 1.5 cups total panko—sprinkle half over the top after the first 20 minutes of baking, then add the remaining half mixed with oil for the final 10-12 minutes. This two-step method prevents sogginess while maximizing crunch. 🌟
Garnish Like a Pro
Fresh chives or green onions add a bright pop of color and freshness—just sprinkle 2 tbsp finely chopped over each serving before passing. For extra flair, I sometimes add crispy fried shallots (store-bought works fine) or toasted breadcrumbs with smoked paprika.
The key is to add garnishes right before serving so they stay crisp.
Serving Styles
For a casual gathering, serve family-style in a large ceramic dish—the crispy edges will hold up beautifully. For a more elegant presentation, portion into individual ramekins and broil for 2-3 minutes after baking to crisp the tops.
I love using mini cast-iron skillets for a rustic touch that keeps everything warm.
Pairing Perfection
This mac and cheese is the ultimate comfort food side, but it stands up to hearty mains too. Pair it with grilled chicken thighs or smoked sausage for a weeknight dinner.
For a vegetarian spread, add roasted Brussels sprouts with balsamic glaze or a simple green salad with apple cider vinaigrette. The tangy dressing cuts through the richness beautifully.
Make-Ahead Magic
Bake the mac and cheese completely, then let it cool to room temperature. Transfer to an airtight container and refrigerate for up to 3 days. To reheat, cover with foil and warm in a 350°F oven for 15-20 minutes until bubbly.
For a crispy top, broil for 1-2 minutes at the end. The flavors actually deepen overnight!
Leftovers Reinvented
Turn cold leftovers into mac and cheese muffins—just portion into greased muffin tins and bake at 375°F for 12-15 minutes until golden. Or make mac and cheese grilled cheese by sandwiching slices between buttered bread and frying in butter until crispy.
These creative uses keep this dish exciting for days. 💫

Frequently asked questions
Can I make this mac and cheese in a smaller dish?
For a 9x13-inch dish, this recipe is perfect. For smaller pans, divide the mixture evenly between two 9x9-inch dishes. Bake times remain the same, but check for doneness at 10 minutes intervals after the initial 20 minutes—smaller pans may need slightly less time. The key is to avoid overcrowding for that crispy top!
Why did my mac and cheese turn out dry?
Dry mac and cheese usually happens from overbaking or not enough sauce. Always bake until the edges are bubbly but the center is still slightly jiggly—30-32 minutes total at 375°F. If your sauce seems too thick, add 1-2 tablespoons of milk or pasta water before baking. The roux should be smooth, not grainy!
Can I use pre-shredded cheese?
Pre-shredded cheese works in a pinch, but block cheese is ideal. Pre-shredded varieties contain anti-caking agents that make the sauce grainy. If you must use them, reduce the amount by 10% since they tend to shrink when melted. For the best texture, grate your own sharp cheddar and Gruyère.
How do I make this vegan?
Swap the dairy for vegan butter, unsweetened almond milk, and vegan cream cheese. Use nutritional yeast for a cheesy flavor and cashew cream (blend soaked cashews with water) instead of heavy cream. For the crispy topping, use vegan breadcrumbs and olive oil. The texture will be slightly lighter but still delicious!
What’s the best way to reheat leftovers?
Cover with foil and reheat at 350°F for 15-20 minutes until bubbly. For extra crispiness, broil for 1-2 minutes at the end. Microwaving works in a pinch, but it can make the top soggy. Leftovers taste even better reheated—the flavors meld beautifully overnight!
