Ingredients for 9 x 13 mac and cheese
Twelve essential ingredients for the ultimate triple-cheese bubble-top mac and cheese.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lb | Al dente, uncooked weight |
| Sharp White Cheddar Cheese 🧀 | 4 oz | Shredded, aged 6+ months |
| Gruyère Cheese 🧀 | 4 oz | Shredded, imported preferred |
| Cream Cheese 🧈 | 8 oz | Full-fat, room temperature |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for richness |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for sauce |
| All-Purpose Flour 🌾 | ¼ cup | For roux, sifted |
| Whole Milk 🥛 | 1 cup | Warm for smooth sauce |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy topping |
| Melted Butter 🧈 | ¼ cup | For breadcrumb mix |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning and water |
| Mustard Powder 🌶️ | ¼ tsp | For depth of flavor |
The cheeses are non-negotiable here. Sharp white cheddar brings the tang, Gruyère adds nutty depth, and cream cheese ensures that signature velvety texture. For the best results, buy pre-shredded cheddar and Gruyère—the anti-caking agents prevent clumping. If you're feeling fancy, Whittard of Chelsea or Murray's Cheese carry excellent imported Gruyère. The cream cheese should be full-fat and at room temperature before mixing—this is where the magic happens.
No Gruyère? Swiss cheese works in a pinch, though it lacks the same depth. The panko breadcrumbs are key for that crispy bubble top—Trader Joe's has the best quality at a reasonable price. If you're out of panko, regular breadcrumbs toasted with butter will do, but they won't be as crispy. The mustard powder might seem odd, but it cuts through the richness and adds a subtle tang that balances the cheeses. For the roux, use a heavy-bottomed saucepan—this prevents burning and ensures a smooth sauce every time.
This dish actually improves overnight, so make it ahead if you can. Store leftovers in an airtight container for up to 5 days. The breadcrumb topping can be prepped separately and stored in the fridge for 3 days—just add the melted butter right before baking. For reheating, cover with foil and warm in the oven at 350°F for 15-20 minutes. The sauce will stay luscious, and the bubble top will crisp up beautifully.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this—no boiling pasta separately, no extra pots, just dump the elbows in with the cheese sauce and bake. The pasta soaks up that Gruyère and cream cheese blend like a dream, and honestly? I’ve never had a single noodle left dry.
- Creamy Crispy Perfection: That sharp white cheddar and Gruyère combo gives it a sharp, nutty bite, while the cream cheese keeps it velvety smooth. The edges get golden and crispy—chef’s kiss—but the center stays rich and gooey. It’s the kind of mac that makes you groan in satisfaction.
- Game for Any Night: Between us, this is my go-to for game days, lazy Sundays, or when I’m too tired to plan dinner. Add a sprinkle of breadcrumbs on top before baking for extra crunch, or keep it simple—either way, it’s always a crowd-pleaser.
- Leftovers That Don’t Suck: I make a double batch on Sundays, and it’s still just as good reheated the next day. The creaminess doesn’t turn greasy, and the cheddar stays melty. Plus, it’s budget-friendly—cheese is cheap in bulk, and a big pan means fewer meals to cook later. Win.
Step-by-step instructions for triple-cheese mac and cheese
Here's the method for creating that signature bubble-top finish with ultra-creamy layers.
Cook the Pasta Al Dente
Bring a large pot of water to a rolling boil and add the 1.5 lb elbow macaroni. Stir immediately to prevent sticking. Season the water with 1.5 tsp Diamond Crystal kosher salt—it should taste like the ocean when you dip a spoon in. Cook until 1 minute shy of package directions for al dente texture. The pasta should have a slight bite when you test it.
Drain the pasta in a colander but don't rinse it—those surface starches are essential for binding the cheese sauce later. Transfer the drained pasta to a large mixing bowl and set it aside. I like to give it a quick shake to break up any clumps before adding the cheese mixture.
Make the Ultra-Creamy Cheese Sauce
In a separate large pot, melt the 0.5 cup unsalted butter over medium heat. Once melted, whisk in the 0.25 cup all-purpose flour to form a roux. Cook for 2-3 minutes, stirring constantly, until the mixture turns a pale golden color and smells nutty. This is your flavor foundation—don't let it brown or it'll taste bitter.
Gradually whisk in the 1 cup whole milk and 1 cup heavy whipping cream, allowing each addition to fully incorporate before adding more. Bring the mixture to a gentle simmer, then reduce heat to low and stir in the 8 oz cream cheese, 4 oz sharp white cheddar cheese, and 4 oz gruyère cheese. The sauce should thicken noticeably as it melts. For extra depth, add the 1 tsp garlic powder, 0.5 tsp ground black pepper, and 0.25 tsp mustard powder. Let it simmer for 3-4 minutes until completely smooth.
Combine Pasta and Cheese
Pour the hot cheese sauce over the drained pasta in the mixing bowl. Using a wooden spoon or rubber spatula, gently fold everything together until the pasta is fully coated and the cheese is evenly distributed. The mixture should look creamy and glossy, with no dry spots. If it seems too thick, add 2-3 tablespoons of pasta water to loosen it to a smooth, sauce-like consistency.
Taste and adjust seasoning if needed—this is your chance to perfect the flavor. I usually add a pinch more salt or pepper at this stage. Transfer the pasta mixture to your 9 x 13-inch baking dish and spread it out evenly, creating a flat surface for the perfect bubble top.
Create the Signature Bubble Top
Preheat your oven to 375°F. In a small bowl, mix together the 0.5 cup panko breadcrumbs and 0.25 cup melted butter until evenly combined. Sprinkle this mixture evenly over the top of the mac and cheese, pressing down gently with the back of a spoon to help it adhere. The butter in the breadcrumbs will create that irresistible crispy, golden crust.
Bake uncovered for 20-25 minutes until the top is deep golden brown and bubbling vigorously. The edges should be crispy while the center remains creamy. If the top browns too quickly, tent loosely with aluminum foil for the last 5-10 minutes of baking.
Rest and Serve
Remove the baking dish from the oven and let it rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly and makes it easier to slice. The mac and cheese will be hot and bubbly—serve immediately while the top is still crispy and the cheese is at its creamiest.
For the best experience, cut into squares and serve with a side of steamed vegetables or a simple green salad. The contrast between the crispy top and creamy interior is what makes this version truly special. Leftovers? Reheat covered in the oven at 350°F for 10-15 minutes to restore that perfect texture.
Pro Tips For Making 9 X 13 Mac And Cheese
- Cook pasta al dente: Elbows should have just a tiny bite—no mush, no crunch. I learned this the hard way when my first batch turned to glue after sitting in the cheese sauce. Drain them, toss with a splash of pasta water, and set aside while you melt the cheeses.
- Grate cheese aggressively: Skip the pre-shredded stuff—it’s full of anti-caking agents that make the sauce grainy. Use a box grater for sharp cheddar and Gruyère, and pulse cream cheese in short bursts so it melts smoothly. (Yes, even if you’re impatient like me.)
- Temper the sauce slowly: Don’t dump cold cheeses into hot cream—it’ll seize up. Melt the cream first, then whisk in the cream cheese until smooth before adding the sharp cheddar and Gruyère. If it looks lumpy, strain it through a fine-mesh sieve.
- Bake covered, then uncover: Start with foil on to melt everything evenly, then remove it for the last 5–7 minutes. This gives you that golden crust without burning the top. (Your future self will thank you.)
Regional styles of these flavors
Southern Comfort Style
In the South, mac and cheese gets a smoky, spiced twist with additions like crispy bacon and a dash of Cajun seasoning. Cook 6 oz bacon until crispy, crumble it into the cheese sauce, and stir in 1 tsp Cajun seasoning (like Tony Chachere's) with the mustard powder.
Top with extra crispy bacon bits before broiling for that signature Southern crunch. 🌶️
New England Clam Chowder Twist
Up north, they take mac and cheese to seafood territory by adding chopped clams and smoked paprika. Stir 1 can chopped clams (drained) and ½ tsp smoked paprika into the cheese sauce.
Finish with a sprinkle of fresh chives and a dash of hot sauce before baking. This version works perfectly as a main dish for chilly New England winters. 🦪
Midwest Casserole Classic
The Midwest keeps it hearty with a brown butter sauce and caramelized onions. Brown ½ cup butter until nutty, then cook 1 cup diced onions until caramelized before making the roux.
Fold the onions into the cheese sauce and top with extra Gruyère before broiling. This version has a deeper, richer flavor that Midwesterners love. 🧀
West Coast Vegan Adaptation
For a plant-based take, swap the dairy for cashew cream sauce and use nutritional yeast for that cheesy flavor. Blend 1.5 cups soaked cashews, 1 cup unsweetened almond milk, 2 tbsp nutritional yeast, and 1 tbsp lemon juice until smooth.
Toss with cooked pasta and top with breadcrumbs mixed with olive oil before baking. 🌱
Texas BBQ Mac
In Texas, they go bold with smoked Gouda and a BBQ sauce drizzle. Replace the Gruyère with 4 oz smoked Gouda and stir ½ cup BBQ sauce (like Stark's) into the cheese mixture.
Top with extra BBQ sauce and crushed tortilla chips before broiling for a smoky, tangy kick. 🍖
Italian-Inspired Formaggio
For an Italian touch, use Parmigiano-Reggiano and Pecorino Romano instead of cheddar. Replace the sharp cheddar with 4 oz each of Parmigiano-Reggiano and Pecorino Romano, and stir in ½ tsp dried oregano with the other spices.
Top with extra grated cheese and toasted pine nuts before broiling for a Mediterranean flair. 🍝

Frequently asked questions
Can I use a different pan size than 9 x 13?
Yes, but you'll need to adjust baking times. For a 8 x 8-inch dish, reduce baking time by 10-15 minutes and cover with foil halfway through to prevent over-browning. For a 11 x 15-inch pan, increase baking time by 5-10 minutes and check for doneness at the center. The key is to maintain a 375°F oven temperature.
Why did my mac and cheese get watery after baking?
Watery mac and cheese usually happens from overcooking the pasta or adding too much liquid. Always cook pasta 1 minute less than package instructions and drain well. If the sauce seems too thin, stir in 1-2 oz extra shredded cheese and let it melt completely before baking. For extra insurance, use 1 cup less milk in the sauce.
How do I make this recipe ahead of time?
This mac and cheese actually tastes better the next day! Assemble the dish completely (including the breadcrumb topping) and refrigerate for up to 24 hours before baking. When ready to bake, add 5-10 minutes to the baking time. For freezing, bake as directed, let cool completely, then wrap tightly in foil and freeze for up to 3 months. Thaw overnight in the fridge.
Can I add cooked vegetables to this recipe?
Stir in 1-2 cups of cooked veggies like broccoli, peas, or diced bell peppers when combining the pasta and cheese sauce. For best texture, use frozen veggies (thawed and drained) or fresh veggies that have been blanched first. Add them just before baking to maintain crispness.
What's the secret to getting that perfect bubble top?
The bubble top magic comes from three things: buttery panko, gentle pressing, and broiling at the end. Mix the breadcrumbs with melted butter (not oil) and press them down lightly before baking. If the top browns too quickly, tent with foil for the last 5 minutes, then broil for 1-2 minutes at the very end for maximum crispiness.
