Ingredients for alex guarnaschelli gnocchi mac and cheese
These 14 ingredients transform simple gnocchi into restaurant-worthy comfort food everyone will beg for seconds of.
| Ingredient | Amount | Notes |
|---|---|---|
| Potato Gnocchi 🍝 | 1 ½ lb | Homemade or store-bought, pillowy texture |
| Unsalted Butter 🧈 | ¾ cup | High-quality, cut into small cubes |
| All-Purpose Flour 🌾 | ¼ cup | For light roux, sifted preferred |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for ultra-rich sauce |
| Sharp Aged Cheddar Cheese 🧀 | 1 ½ cups | Shredded, 2+ year aged preferred |
| Gruyère Cheese 🧀 | 1 cup | Shredded, nutty flavor essential |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated, for umami depth |
| Whole Milk 🥛 | ½ cup | Warmed for smooth sauce |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns preferred |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste, don't skip |
| Panko Breadcrumbs 🍞 | ½ cup | Toasted for extra crunch |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For pan-toasting gnocchi |
| Garlic Cloves 🧄 | 2 cloves | Minced, for aromatic base |
| Fresh Nutmeg 🌿 | ¼ tsp | Freshly grated, optional but magical |
The gnocchi makes or breaks this dish—homemade is ideal, but Biondi-Santi or De Cecco from the Italian market section work beautifully. Look for gnocchi with visible potato flecks; those store-bought tubes with no texture? Skip 'em. The cheeses are non-negotiable: sharp aged cheddar for tang, Gruyère for nutty depth, and freshly grated Parmesan for umami. I always grab mine from Whole Foods or Eataly—the difference in quality is night and day compared to pre-shredded supermarket cheese. For the butter, Plugrá or Land O'Lakes cultured gives the best flavor when browned.
No aged cheddar? Pecorino Romano at half the amount adds similar sharpness. Fresh nutmeg giving you trouble? Ground nutmeg works in a pinch, but trust me on the fresh version—it's worth the extra minute. The panko topping can be swapped for crushed cornflakes if you're out, though it'll be slightly sweeter. For the roux, don't rush the cooking—golden brown, not burnt. That's where the flavor develops. And if you're feeling fancy, add a splash of white wine when deglazing the pan for extra brightness.
This reheats beautifully—honestly tastes better the next day once everything melds. Keeps 4-5 days in the fridge, freezes for 3 months if portioned properly. I always make extra because it's the kind of dish that disappears fast. Store leftovers covered with a layer of plastic wrap pressed directly on the sauce to prevent a skin from forming. For serving, I like to transfer to a baking dish, broil for 2-3 minutes until the topping is golden—that's when you know it's perfect.

Step-by-step instructions for alex Guarnaschelli's gnocchi mac and cheese
This ultra-rich, pillowy gnocchi mac and cheese delivers restaurant-quality comfort food at home.
🍳 Step 1: Toast the Gnocchi for Maximum Crisp
Heat the 2 tablespoons extra-virgin olive oil in a large oven-safe skillet over medium-high heat. Add the 1.5 lb potato gnocchi in a single layer, leaving space between each piece. Let them cook undisturbed for 3-4 minutes until golden brown spots appear—this creates that perfect crispy exterior we're after.
Here's the thing—don't crowd the pan. If you need to work in batches, that's fine, but give each gnocchi room to brown. Once golden on one side, gently flip and toast the other side for another 2-3 minutes. Remove the gnocchi and set aside on a plate, but keep the skillet warm for the next step.
👨🍳 Step 2: Build the Ultimate Cheese Sauce
Reduce the heat to medium and add the 0.75 cup unsalted butter to the warm skillet. Let it melt completely, then whisk in the 0.25 cup all-purpose flour to create a light roux. Cook for 1-2 minutes until the mixture smells nutty and turns a pale golden color—this is your flavor foundation.
Gradually whisk in the 1.5 cups heavy cream and 0.5 cup whole milk, letting the sauce thicken between each addition. Once fully combined, reduce heat to low and stir in the 1.5 cups sharp aged cheddar cheese, 1 cup gruyère cheese, and 0.5 cup parmesan cheese until completely melted and smooth. Season with 1.5 tsp diamond crystal kosher salt and 0.5 tsp freshly ground black pepper. For that magical touch, add the 0.25 tsp freshly grated nutmeg—it's what elevates this from good to extraordinary.
🍳 Step 3: Combine and Create the Perfect Texture
Return the toasted gnocchi to the skillet with the cheese sauce. Stir gently but thoroughly to coat each piece evenly. The sauce should cling beautifully to that pillowy texture—this is where the magic happens. If the sauce seems too thick, add 1-2 tablespoons warm milk to reach your desired consistency. Let the whole dish simmer together for 2-3 minutes until everything is heated through and the cheeses have fully melded.
Here's where precision matters: the gnocchi should be hot but not overcooked, and the sauce should be silky without being runny. Taste and adjust seasoning—you might need a touch more salt or pepper to balance the rich cheeses.
🥘 Step 4: Add the Crunchy Topping
Transfer the gnocchi mac and cheese to oven-safe serving dishes. Sprinkle the 0.5 cup toasted panko breadcrumbs evenly over the top, pressing down gently so they stick. For extra flavor, add the 2 cloves minced garlic to the breadcrumbs before toasting them in a dry skillet over medium heat for 1-2 minutes until golden and fragrant.
Broil on high for 2-3 minutes until the breadcrumbs turn a deep golden brown and are crispy to the touch. Watch carefully—this happens fast! The broiler creates that perfect textural contrast we crave in mac and cheese.
🍽️ Step 5: Rest and Serve Like a Pro
Let the dish rest for 3-5 minutes before serving. This might seem counterintuitive, but it allows the breadcrumbs to crisp up further and the sauce to set slightly, making each bite cleaner and more satisfying. Serve immediately with a side of simple arugula salad or roasted broccoli to cut through the richness.
Here's the pro tip: if you're serving this to a crowd, keep the broiler on and add fresh breadcrumbs to any plates that cool down—it makes all the difference in that first bite.
Pro Tips For Making Alex Guarnaschelli Gnocchi Mac And Cheese
- CRANK THE CREAM HEAT: The roux in this recipe isn’t just flour and butter—it’s the foundation. Cook it over medium-low heat until it’s a deep, nutty golden color, not white. I used to rush it, and the sauce would taste raw. Give it 5-7 minutes, stirring constantly, or you’ll end up with a gluey mess instead of that rich, velvety base.
- GRATE CHEESE FRESH: Pre-shredded cheddar has anti-caking agents that turn your sauce into a clumpy disaster. Use a box grater and shred the cheese yourself—it’s faster than you think. Sharp aged cheddar is non-negotiable here; the nuttiness cuts through the creaminess, and store-bought shreds just won’t give you that same depth.
- RESERVE THE GNOCHI WATER: That starchy water from boiling gnocchi isn’t waste—it’s liquid gold. Skim ½ cup before draining and swirl it into your finished sauce. It helps emulsify the cheese and adds a subtle chewiness that makes the dish feel more cohesive. (Yes, even if you’re impatient like me.)
- STIR IN THE GNOCHCHI RIGHT: Don’t just dump the gnocchi in and call it a day. Fold them in gently with a spatula or wooden spoon, letting the sauce cling to them. If you toss them in too fast, you’ll end up with dry, separate dumplings instead of a creamy, unified bite. Think of it like tucking in a picky eater—patience pays off.
Make-ahead tips for leftovers
Prep Ahead Timeline
Start by prepping the gnocchi and cheese sauce components separately the night before. Toast the 1.5 lb gnocchi in batches and store in an airtight container at room temperature—this prevents sogginess.
For the sauce, make the roux and shred all cheeses, storing them separately in the fridge. This saves 30-45 minutes on cooking day. 📅
Freezer-Friendly Method
Assemble the dish completely (gnocchi + sauce) in a freezer-safe baking dish, then cover tightly with plastic wrap and foil. Freeze for up to 3 months. When ready to serve, thaw overnight in the fridge, then broil for 5-7 minutes with fresh breadcrumbs to restore crispiness.
The texture remains perfect—no freezer burn in sight!
Batch Cooking Tips
Double the recipe for gatherings—this mac and cheese reheats beautifully. Store in individual portions in glass Pyrex dishes (they handle reheating better than plastic). Reheat covered at 350°F for 15-20 minutes or until bubbly. The sauce thickens slightly when reheated, so add 1 tbsp warm milk if needed. ✨
Make-Ahead Mistakes
Avoid these common pitfalls: Don't store the toasted gnocchi in the fridge (it goes soggy), and never assemble the full dish ahead—always combine sauce and gnocchi fresh.
For the breadcrumb topping, toast it fresh before serving to guarantee maximum crunch. Pro move: Keep a stash of pre-toasted breadcrumbs in the freezer for quick assembly.
Holiday Party Hack
For stress-free entertaining, prep everything except the final broil step. Keep the assembled dish in a slow cooker on warm while guests arrive. When ready to serve, transfer to baking dishes, add breadcrumbs, and broil.
This keeps the dish hot and creamy with minimal last-minute work. Perfect for Thanksgiving or Christmas dinners!
Leftovers Reinvention
Transform leftovers into gnocchi mac and cheese croquettes! Shape the cooled mixture into balls, coat with panko mixed with Parmesan, and pan-fry until golden. Serve with marinara sauce for a completely different (but equally delicious) meal. This extends your dish's life by 2-3 extra servings without waste. 💫

Frequently asked questions
Why does Alex Guarnaschelli's recipe use both aged cheddar and Gruyère?
The combination creates the perfect balance of flavors. Sharp aged cheddar provides that signature tangy richness, while Gruyère adds nutty depth and a creamy texture that prevents the sauce from becoming too heavy. The Parmesan finishes with umami complexity—together, they create a sauce that's both luxurious and well-rounded.
Can I make this recipe with regular macaroni instead of gnocchi?
While you can substitute, you'll lose the signature pillowy texture that makes this dish special. If you must, use large shell pasta or giant cavatappi for better sauce adhesion, but the experience won't be the same. The gnocchi's porous surface is key to creating those perfect sauce pockets.
How do I fix a sauce that's too thick or too thin?
For a thick sauce, whisk in 1-2 tablespoons warm milk gradually until smooth. If it's too thin, remove from heat and let it rest for 2-3 minutes—the starch will activate and thicken naturally. As a last resort, mix 1 teaspoon cornstarch with 1 tablespoon cold water, then stir in carefully.
What's the best way to reheat leftovers without drying out the gnocchi?
Cover the dish with foil and reheat in a 350°F oven for 15-20 minutes—this keeps everything creamy. For microwave reheating, cover with a damp paper towel and heat in 30-second intervals, stirring between each. Always add 1 tablespoon warm milk to restore silkiness.
Can I make this dish vegetarian or vegan?
For vegetarian, use dairy-free butter and plant-based cream, replacing cheddar with vegetarian cheddar and Gruyère with nutritional yeast for umami. For fully vegan, substitute all dairy with cashew cream** and vegan cheese alternatives. The texture will differ, but the technique remains the same—just be prepared for a lighter sauce.
