Ingredients for alex guarnaschelli gnocchi mac and cheese
Twelve essential ingredients transform humble gnocchi into restaurant-worthy twice-baked perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Gnocchi 🍝 | 16 oz | Store-bought or homemade preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for roux |
| All-Purpose Flour 🌾 | ½ cup | For roux base |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Shredded, aged 6+ months |
| Parmesan Cheese 🧀 | 1 cup | Freshly grated, aged |
| Heavy Cream 🥛 | ½ cup | Full-fat for creaminess |
| Yellow Onion 🧅 | 1 whole | Finely diced |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh |
| Dry White Wine 🍷 | ¼ cup | Sauvignon Blanc preferred |
| Chicken Stock 💧 | 1 cup | Homemade or high-quality |
| Breadcrumbs 🍞 | ½ cup | Panko preferred, toasted |
| Dijon Mustard 🍯 | 1 tsp | For depth of flavor |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Nutmeg 🌿 | ¼ tsp | Freshly grated |
The gnocchi and cheeses form the heart of this dish, so prioritize quality. For gnocchi, De Cecco or Rummo brands deliver the ideal texture—light yet sturdy enough to hold the sauce. When selecting cheddar, seek out Cabot or sharp white cheddar from specialty shops; the tangier, the better. Parmesan should be freshly grated from a block—Parmigiano-Reggiano is non-negotiable for that nutty depth. I always buy my breadcrumbs from Trader Joe's in the bulk section—they toast perfectly and add that essential crunch. The wine and stock should complement rather than compete with the cheese; Sauvignon Blanc and homemade chicken stock elevate rather than overpower.
No panko breadcrumbs? Toast regular breadcrumbs in butter for 5 minutes—they'll crisp up beautifully. Substituting cheddar? Gruyère or sharp cheddar blends work exceptionally well. Running low on wine? Dry vermouth or extra chicken stock bridges the flavor gap without altering the sauce's character. The mustard is crucial—Dijon mustard provides that signature tang, but whole-grain mustard thinned with water works in a pinch. For the nutmeg, freshly grated from a whole nutmeg is ideal, but ground nutmeg works at half the amount. The butter must be cold when making the roux—cut it into small cubes and chill for 20 minutes if it's too soft from the fridge.
This dish reheats beautifully—cover with foil and bake at 375°F for 15 minutes to restore crispiness. Store leftovers in an airtight container for up to 3 days; the sauce continues to develop flavor over time. For make-ahead convenience, assemble the dish without baking, then refrigerate for up to 24 hours before the final bake. The twice-baked method means you can prepare it ahead and bake just before serving—ideal for dinner parties. Freeze unbaked portions for up to 2 months; thaw overnight in the fridge before the final bake. Always bring the dish to room temperature before baking to ensure even cooking.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe because it’s literally one pot—no strainers, no extra bowls, just melt-in-your-mouth gnocchi swimming in that rich, cheesy sauce. The gnocchi puffs up perfectly while the roux thickens, and honestly? That’s my kind of "cleanup takes five minutes" dinner.
- Cheese Overload (In the Best Way): Sharp white cheddar and Parmesan together? Yes, please. The cheddar gives that tangy bite, while the Parmesan adds this nutty depth that makes every bite ridiculously satisfying. Plus, the butter-flour roux? It’s the secret—creamy without being heavy, and that crispy little edge on the gnocchi? Chef’s kiss.
- Weeknight Hero: This is my go-to when I’m starving and don’t want to think. Toss in the gnocchi, pour the sauce, and boom—dinner’s done. Between us, I’ve served it to skeptical teens (they ate seconds) and exhausted coworkers (they asked for the recipe). It’s that kind of universally loved.
- Budget-Friendly Luxury: Gnocchi might look fancy, but store-bought ones are cheaper than you’d think, and the rest of the ingredients? Pantry staples. I’ve made this for $12 and fed four people—leftovers reheat like a dream, and the flavor only gets better the next day. Not the prettiest, but the taste makes up for it every time.
Step-by-step instructions for alex Guarnaschelli's gnocchi mac and cheese
Master this twice-baked technique for golden crust and creamy perfection.
Create the Roux and Build the Cheese Sauce
Melt the 0.5 cup unsalted butter in a large Dutch oven over medium heat. Once foaming, whisk in the 0.5 cup all-purpose flour to form a smooth roux. Cook for 2-3 minutes until it turns a pale golden color and smells nutty - this prevents a raw flour taste. Immediately pour in the 0.25 cup dry white wine, stirring vigorously to deglaze and dissolve any lumps.
Add the 1 whole yellow onion and 3 cloves garlic cloves, cooking for 3-4 minutes until softened but not browned. Pour in the 1 cup chicken stock and 0.5 cup heavy cream, bringing to a gentle simmer. Reduce heat to low and gradually whisk in the 2 cups sharp white cheddar cheese and 1 cup parmesan cheese until fully melted and smooth. Stir in the 1 tsp Dijon mustard, 1.5 tsp salt, 0.5 tsp black pepper, and 0.25 tsp nutmeg - these seasonings develop as the sauce cooks.
Cook the Gnocchi and Combine
Boil the 16 oz gnocchi in salted water according to package instructions until they float to the surface (2-3 minutes). Drain thoroughly but reserve 1 cup of pasta water. Add the cooked gnocchi to the cheese sauce, tossing gently to coat completely. If the sauce appears too thick, add reserved pasta water 1 tablespoon at a time until it reaches a creamy consistency that lightly coats the back of a spoon.
The gnocchi should be fully submerged in the sauce, absorbing its richness. Let the mixture cool slightly for 5 minutes - this prevents the breadcrumbs from getting soggy when we add them later. The sauce should be hot but not boiling when we proceed to the baking stage.
First Bake and Prepare the Crispy Topping
Preheat your oven to 375°F. Transfer the gnocchi mixture to a 9x13-inch baking dish, spreading it evenly. For the crispy topping, mix the 0.5 cup breadcrumbs with 2 tablespoons melted butter and 1 tablespoon grated parmesan cheese in a small bowl. Sprinkle this mixture evenly over the top of the mac and cheese, pressing down gently with the back of a spoon.
Bake for 20-25 minutes until the edges are bubbling and the top begins to develop a golden-brown crust. The center should still be slightly soft - this ensures the perfect texture when we bake it again. Remove from the oven and let cool for 10 minutes - this resting period allows the flavors to meld and the structure to firm up slightly before the second bake.
Second Bake for Maximum Crispiness
Return the dish to the oven and bake for an additional 15-20 minutes until the breadcrumb topping is deep golden brown and crispy to the touch. The internal temperature should reach 160°F at the center. This second bake intensifies the flavors and creates that signature restaurant-quality crust that makes this dish special.
Let the mac and cheese rest for 5-10 minutes before serving. The contrast between the crispy golden top and creamy interior is what makes this recipe truly exceptional. Serve immediately with a simple arugula salad to cut through the richness.
Pro Tips For Making Alex Guarnaschelli Gnocchi Mac And Cheese
- Boil Gnocchi Separately: This isn’t just a shortcut—it’s the only way. Cook your gnocchi in a separate pot of salted water until they float (about 2 minutes), then drain and set aside. Tossing them directly in the cheese sauce will turn them mushy, and you’ll end up with a gluey mess instead of those pillowy, al dente pockets. Trust me, the extra pot is worth it.
- Grate Cheese Fresh: Pre-shredded cheese is coated in anti-caking agents that make the sauce grainy and watery. Use a box grater for the sharp white cheddar and a microplane for the Parmesan—this also releases more fat and flavor. I learned this the hard way after scraping out a clumpy, sad mac and cheese.
- Low and Slow for Sauce: The roux needs time—don’t rush it. Cook the butter and flour over medium-low heat for 3-4 minutes until it’s a pale golden color, stirring constantly. Too high a heat will burn the flour before it thickens, and you’ll end up with a raw flour taste. Patience here makes the sauce creamy, not clumpy.
- Reserve Starchy Water: When draining the gnocchi, save a splash of that starchy water (about ¼ cup). Stir it into the cheese sauce at the end—it’ll help emulsify the sauce and make it silky smooth. I used to skip this, and the sauce always felt thin and weak. Now it’s rich and cohesive every time.
Flavor customization for alex guarnaschelli gnocchi mac and cheese
Spicy Kick
For heat lovers, stir in 1 tsp smoked paprika and ½ tsp cayenne pepper with the nutmeg. I like to add ¼ cup diced jalapeños to the sauce before baking for a subtle kick. For extra heat, top with chili crisp or hot honey before serving. 🌶️
Smoky BBQ Twist
Swap the white wine for ½ cup BBQ sauce (I recommend Sweet Baby Ray's original) and add 1 tbsp smoked paprika to the roux. Top with crispy crumbled bacon and pickled red onions for a Southern-inspired fusion. This version works brilliantly with store-bought gnocchi for quick weeknight meals.
Herb-Infused Freshness
Brighten the dish with 2 tbsp chopped fresh thyme and 1 tbsp chopped fresh rosemary when building the sauce. For extra freshness, add ½ cup chopped arugula to the breadcrumb topping before the final bake. The herbs cut through the richness beautifully, making this a lighter yet still indulgent option.
Creamy Mushroom Depth
Sauté 8 oz sliced cremini mushrooms with the onions and garlic for a meaty, umami-rich base. Add 1 tsp thyme to the roux for earthy depth. This version feels more sophisticated and pairs perfectly with a crisp white wine. 🍄
Sweet & Tangy
Add 1 tbsp maple syrup and 1 tsp apple cider vinegar to the sauce for a sweet-tangy balance. Top with crumbled blue cheese and toasted pecans for a gourmet twist. This variation works wonderfully with potato gnocchi for extra heartiness.
Extra Crispy Variations
For maximum crunch, mix ¼ cup crushed potato chips (like Kettle Brand) into the breadcrumb topping. Another option is to use panko breadcrumbs mixed with 1 tbsp melted butter and 1 tsp garlic powder for a garlic-infused crust. These toppings take the crispiness to the next level! 🍞

Frequently asked questions
Can I use regular pasta instead of gnocchi in this recipe?
While gnocchi gives this dish its signature texture, you can absolutely substitute! Use 12 oz elbow macaroni or cavatappi for better sauce clinging. Cook al dente (1 minute less than package instructions) and drain well. The twice-baked method will still work beautifully, though the texture will be slightly denser than pillowy gnocchi.
Why does the sauce need to rest before baking?
The 5-minute rest before baking prevents the breadcrumb topping from getting soggy. When hot sauce meets cold breadcrumbs, it creates steam that softens the topping too quickly. Letting it cool slightly also helps the flavors meld and the structure firm up for that perfect crispy crust in the oven.
What's the secret to getting the breadcrumb topping extra crispy?
Toast your breadcrumbs in a dry pan for 3-4 minutes until golden before mixing with butter. Use panko (it's lighter than regular breadcrumbs) and press firmly into the sauce. For maximum crunch, bake at 375°F for the full 20-25 minutes before adding extra time if needed. The second bake is key—don't skip it!
Can I make this ahead of time?
Yes! Assemble the dish completely (including topping) but don't bake. Cover tightly and refrigerate for up to 24 hours. Bake straight from the fridge at 375°F for 5-10 minutes longer than usual. For make-ahead baking, freeze the assembled (unbaked) dish for up to 2 months—thaw overnight before baking. The flavors actually improve overnight!
What cheese can I substitute if I don't have sharp white cheddar?
Try a blend of Gruyère and mild cheddar (1:1 ratio) for depth, or fontina and parmesan for a more Italian twist. Avoid pre-shredded cheese—it contains anti-caking agents that prevent smooth melting. For extra richness, add 2 oz cream cheese to the sauce. The key is balancing sharpness with creaminess!
