Alex Guarnaschelli's gnocchi mac and cheese recipe transforms comfort food into a restaurant-worthy dish with crispy golden edges and pillowy gnocchi. The secret lies in boiling gnocchi just until they float, then combining them with a velvety cheese sauce that clings perfectly.
This isn't your childhood mac and cheese—it's a sophisticated, cheesy masterpiece that balances textures and flavors effortlessly.

The gnocchi makes or breaks this dish. Fresh is ideal—look for ridged, never pre-boiled varieties at specialty stores like Whole Foods or Eataly. If using dried, choose De Cecco or Barilla brands, which cook evenly. The cheeses? Sharp white cheddar from Vermont (like Cabot) and Gruyère from France (aged 18+ months) are non-negotiable—they melt into velvety layers. For Gruyère, Mile-Haut or Montagne d'Or deliver that nutty depth. The cream cheese? Philadelphia Original is the gold standard, but Kirkland Signature works too.
No sharp cheddar? Pecorino Romano adds saltiness, while Comté brings caramel notes. Fresh gnocchi unavailable? Potato gnocchi from the Italian section (like Rummo) works in a pinch—just check the package for pre-boiled labels. The crispy topping requires Panko (not regular breadcrumbs)—it's the secret to that satisfying crunch. For extra richness, swap 2 tbsp of the heavy cream for crème fraîche. The mustard powder? Stoneground from Penzeys adds complexity without overpowering.
Gnocchi cooks in 2-3 minutes—test by dropping one in boiling water. If it floats immediately, it's done. The cheese sauce can be made 1 day ahead and reheated gently. For the crispy topping, toast the panko in olive oil until golden before adding. Store leftovers 3-4 days in the fridge, but honestly, it's best fresh. The crispy layer loses its crunch after 24 hours—reheat covered to preserve texture. For serving, garnish with parsley and extra black pepper right before eating.

Step-by-step instructions for alex Guarnaschelli's gnocchi mac and cheese
Here's the method that delivers that signature crispy crust, creamy sauce, and perfectly pillowy gnocchi.
Cook the Gnocchi to Pillowy Perfection
Bring a large pot of water to a rolling boil and add the 1 lb gnocchi. Cook until they float to the surface, which typically takes 2-3 minutes. This quick cook time is crucial—overcooking turns gnocchi dense rather than pillowy.
Drain immediately and transfer to a large bowl. Toss the gnocchi with 1 tablespoon extra-virgin olive oil while still hot to prevent sticking. Set aside and keep warm. The oil helps maintain their texture while we build the sauce.
Build the Cheese Sauce Foundation
In a separate large skillet, melt 4 tablespoons unsalted butter over medium heat. Add the 2 cloves minced garlic and sauté for 30 seconds until fragrant but not browned. This step develops flavor without bitterness.
Reduce heat to low and add the 8 oz cream cheese, stirring constantly until fully melted and smooth. The sauce should thicken slightly but remain creamy. Here's the thing—don't rush this step. The cream cheese needs time to emulsify properly, preventing a greasy texture later.
Incorporate the Cheese Blend
Add the 2 cups sharp white cheddar cheese and 1 cup gruyère cheese to the skillet. Stir vigorously until completely melted and the mixture reaches 160°F—this ensures all the cheese is fully incorporated without scorching. The gruyère adds that signature nutty depth while the cheddar provides the classic tang.
Remove from heat and stir in the 1 cup heavy whipping cream, 1 tablespoon nutritional yeast, and 0.5 teaspoon mustard powder. The nutritional yeast adds umami complexity while the mustard powder provides subtle tang. This is where the sauce transforms from ordinary to extraordinary.
Combine and Create the Crispy Topping
Add the cooked gnocchi to the cheese sauce and toss gently to coat evenly. The residual heat from the gnocchi will help melt any remaining cheese. Season with 1.5 teaspoons diamond crystal kosher salt and 0.5 teaspoon freshly ground black pepper. Taste and adjust if needed—this is where you can fine-tune the balance of saltiness and richness.
Transfer the mixture to a 9x13-inch baking dish and spread evenly. In a small bowl, combine the 0.5 cup panko breadcrumbs with 1 tablespoon extra-virgin olive oil. Sprinkle this mixture evenly over the top of the gnocchi-cheese combination. This creates the signature crispy crust that's the hallmark of this dish.
Bake to Golden Crispiness
Preheat your oven to 375°F. Bake for 15-20 minutes until the top is deep golden brown and the edges bubble slightly. The panko should be crispy enough to hold its shape when pressed gently with a spoon.
Let rest for 5 minutes before serving. This resting period allows the cheese to set slightly while maintaining that creamy texture. Garnish with 0.25 cup finely chopped fresh parsley just before serving to add freshness and visual appeal. Each bite should deliver that perfect combination of crispy top, creamy sauce, and pillowy gnocchi.
Pro Tips For Making Alex Guarnaschelli Gnocchi Mac And Cheese
- Cook Gnocchi Until Floating: Gnocchi should dance like a buoy—not sink like a stone. Toss them in boiling salted water and pull them when they float and the water’s just starting to bubble aggressively around them. Overcooking turns them gummy, and undercooking leaves them dense. Trust the float test, not the clock.
- Shred Cheese Coarse: Skip the food processor for sharp white cheddar—it turns into glue. Use a box grater or knife to shred it into uneven chunks, no smaller than rice grains. The texture stays sharp and melts better, and you’ll avoid that sad, pasty sauce. (Yes, it’s more work, but your mouth will notice.)
- Temper the Cream: Warm the heavy cream slowly off the heat before stirring it into the cheese. Cold cream shocks the dairy and makes the sauce split like a bad joke. Heat it in a separate pot until it’s just steaming—about 160°F—then pour it in. Smooth every time.
- Reserve Starchy Water: Save a ladleful of that gnocchi water before draining. Stir a splash into the finished cheese sauce if it’s too thick—it’s like liquid glue for binding. No need for extra cream or butter; you’ve got the magic already. (I learned this after three lumpy batches.)
Storing and reheating your leftovers
Refrigerator Storage
Store leftovers in an airtight container for up to 3-4 days—the crispy panko topping will lose its crunch after 24 hours, but the creamy gnocchi-cheese combo stays delicious. Let it cool completely before refrigerating to prevent condensation, which can make the sauce watery.
I like using glass storage containers (like Pyrex) because they keep flavors sealed better than plastic. 🥫
Freezer-Friendly Method
For longer storage, freeze portions in single-serving airtight containers for up to 2 months. The crispy topping won’t survive freezing, so skip it and add fresh panko after reheating.
Thaw overnight in the fridge, then reheat gently to restore creaminess. I’ve found Ziploc Freezer Gallon Bags work well—just squeeze out excess air before sealing. 🧊
Reheating for Creamy Perfection
For the best texture, reheat in a skillet over medium-low heat with a splash of heavy cream or milk (about 2 tablespoons) to restore creaminess. Cover with a lid and warm for 5-7 minutes, stirring occasionally, until heated through.
Microwaving works in a pinch—use 50% power for 2-minute intervals, stirring between each, until 165°F internal temperature is reached. 🔥
Crispy Topping Revival
If you reheat the dish with the crispy topping, cover it loosely with foil to prevent over-browning. For extra crunch, sprinkle fresh panko breadcrumbs on top and broil for 2-3 minutes at the end.
I’ve also had success using a handheld torch to crisp the edges right before serving—it adds a restaurant-quality finish. 💫
Garnish Like a Pro
Always add fresh parsley and a crack of black pepper right before serving to brighten flavors. For extra depth, a drizzle of truffle oil (just ½ teaspoon) or a sprinkle of smoked paprika elevates the dish. The key is to garnish after reheating—this keeps everything fresh and vibrant. ✨
Make-Ahead Sauce Hack
Prep the cheese sauce 1 day ahead and store it in the fridge. Reheat gently in a saucepan over low heat, stirring constantly, until smooth. This shortcut saves time while keeping the sauce silky.
Just toss the cooked gnocchi in the warmed sauce, top with fresh panko, and bake as directed. Time-saver alert! ⏰

Frequently asked questions
Can I substitute regular pasta for gnocchi in this recipe?
While you can technically use pasta, the texture will be completely different. Gnocchi's pillowy, potato-based nature absorbs the cheese sauce differently, creating those signature creamy "rivers." For a similar effect, try potato gnocchi-shaped pasta like De Cecco's gnocchi pasta—it has ridges that catch the sauce better than smooth pasta. But for authentic results, stick with real gnocchi!
Why does my cheese sauce get grainy instead of smooth?
Graininess usually means the cheese didn't melt properly or the sauce got too hot. Always melt cheeses slowly over low heat while stirring constantly—never let it boil. For extra smoothness, add a splash of heavy cream or milk when combining cheeses. Also, ensure your cheddar is shredded fresh (not pre-shredded, which contains anti-caking agents). The 160°F target temperature is key!
Can I make this dish ahead of time?
Yes! Assemble everything except the crispy topping, then refrigerate for up to 24 hours. When ready to serve, bake uncovered at 375°F for 20-25 minutes (longer than fresh because it's cold). For the crispy topping, add fresh panko and broil for 2-3 minutes at the end. The sauce will be even creamier after chilling!
What's the best way to reheat leftovers without losing the crispy top?
Reheat in a skillet over medium-low heat with 2 tablespoons of heavy cream to restore creaminess, then cover loosely with foil. For the crispy finish, sprinkle fresh panko on top and broil for 2 minutes right before serving. Microwaving? Use 50% power for 2-minute intervals—it won't recreate the crispy texture, but keeps the gnocchi tender.
Can I make this vegetarian or vegan?
For vegetarian, use vegan butter and vegan cream cheese (like Kite Hill), plus vegan cheddar (like Violife) and Gruyère alternatives. For vegan gnocchi, look for potato-based vegan gnocchi (like Banza) or make your own with mashed potatoes and flour. The crispy topping can stay the same—just ensure all cheeses are plant-based.
