Ingredients You'll Need
Great recipes start with great ingredients, but that doesn’t mean you need to break the bank. Here’s what to look for—and what to avoid—when shopping for this cozy skillet supper.
Potato gnocchi: Fresh, shelf-stable, or frozen all work here. If you have access to a local Italian deli that makes them daily, treat yourself. Otherwise, the vacuum-sealed shelf-stable variety (usually found near the dried pasta) is reliable and cooks in two minutes. Avoid the “cauliflower” or “keto” versions; they shed moisture and dilute the brown-butter flavor.
Unsalted butter: You’ll brown eight tablespoons, so use a brand you love. European-style butters with slightly higher fat content (like Plugrá or Kerrygold) brown more evenly and taste richer. If you only have salted butter, reduce the final seasoning by half.
Fresh sage: Look for perky, silvery-green leaves with no black spots. The aroma should hit you the moment you open the plastic clamshell—herbaceous, slightly piney, almost eucalyptus-like. Dried sage won’t crisp in the butter, so skip it here.
Walnuts: Buy halves or large pieces, then toast and chop them yourself; pre-chipped nuts are often stale. If your walnuts smell even a little rancid (cardboard-y or paint-like), compost them and substitute pecans.
Garlic: One plump clove, smashed and gently sizzled in the brown butter, perfumes the entire dish. Green garlic shoots signal age—avoid those bulbs.
Lemon: A whisper of zest lifts the richness; use organic if possible since you’re eating the peel.
Parmesan: A micro-planed snowfall of real Parmigiano-Reggiano melts into the hot gnocchi and emulsifies the sauce. If you’re vegetarian, look for cheese made with microbial rennet. Vegans can swap in two tablespoons of nutritional yeast for a similar umami punch.
Reserved pasta water: The secret weapon. Starchy water loosens the brown-butter glaze into a silky emulsion that clings to every ridge of gnocchi. Don’t forget to save it before you drain the pot!
How to Make Warm Brown Butter Gnocchi with Sage and Walnuts
Toast the walnuts
Preheat a medium heavy skillet (stainless or cast iron) over medium heat. Add ½ cup walnut pieces and toast, stirring often, until they smell nutty and take on a shade darker, 4–5 minutes. Transfer to a cutting board, let cool, then coarsely chop. Set aside. (This step can be done up to three days ahead; store the cooled nuts in an airtight jar.)
Brown the butter
Return the same skillet to medium heat and add 8 Tbsp unsalted butter, cut into tablespoons so it melts evenly. Swirl occasionally. After about 3 minutes the butter will foam, then the milk solids will sink and turn chestnut-brown. Once you see those amber flecks and smell a nutty, caramel aroma, drop in 1 smashed garlic clove and 10–12 sage leaves. The leaves will crisp in 20–30 seconds; use a fork to flip them so both sides blister. Remove the garlic before it burns.
Cook the gnocchi
Meanwhile, bring a medium pot of well-salted water to a boil (1 tsp kosher salt per quart). Add 1 lb potato gnocchi and stir gently so they don’t stick. As soon as they float—usually 90 seconds for shelf-stable, 2–3 minutes for fresh—use a spider or slotted spoon to transfer them directly into the skillet of brown butter. Save ½ cup starchy cooking water before you drain.
Emulsify the sauce
Toss the gnocchi in the brown butter over medium-low heat. Add ¼ cup reserved pasta water and ¼ cup finely grated Parmesan. Swirl the pan until the cheese melts and the sauce thickens into a glossy coating. If it looks tight, splash in more water a tablespoon at a time; you want it to pool slightly but not swim.
Season and finish
Taste. Add ½ tsp kosher salt and ¼ tsp freshly cracked black pepper. Toss in the chopped walnuts and the crisp sage leaves (crumble them between your fingers for little savory flecks). Finish with ½ tsp finely grated lemon zest for brightness.
Serve immediately
Divide among warm shallow bowls. Shower with more Parmesan and an extra drizzle of brown butter from the pan. Serve with crusty bread and a crisp arugula salad dressed simply with lemon and olive oil.
Expert Tips
Control the heat
Butter goes from brown to burnt in seconds. As soon as you see amber flecks, drop the heat to low and add the sage; the cool leaves will arrest the cooking.
Starchy water is liquid gold
Under-salt the gnocchi water and your final dish will taste flat. Aim for pleasantly salty like the sea.
Double the butter
Brown an extra 4 Tbsp and keep it in a jar in the fridge. You’ll have instant sauce for vegetables, fish, or scrambled eggs all week.
Crisp sage ahead
Fry the sage leaves in olive oil, drain on paper towels, and store airtight. They stay crisp for 48 hours—great garnish for soups or roasted squash.
Gnocchi from scratch
If you’re feeling ambitious, homemade ricotta gnocchi (no potatoes) cook even faster and taste like little clouds. Make them the day before and refrigerate on a semolina-dusted tray.
Add color
A handful of baby spinach or halved cherry tomatoes tossed in at the end wilts ever so slightly and makes the dish photograph like a dream.
Variations to Try
-
Autumn squash: Fold in 1 cup roasted cubes of butternut or delicata squash along with the walnuts for a heartier vegetarian main.
-
Pancetta & pea: Render 2 oz diced pancetta until crisp; omit the walnuts and add ½ cup thawed frozen peas for a salty-sweet contrast.
-
Lemon-poppy: Swap walnuts for toasted poppy seeds and finish with an extra squeeze of lemon—bright and addictive.
-
Spicy kale: Stir in 1 cup finely shredded kale and a pinch of red-pepper flakes; the residual heat wilts the greens perfectly.
-
Gorgonzola drizzle: Crumble ¼ cup mild Gorgonzola with 2 Tbsp heavy cream and dollop over each plate for a creamy, tangy finish.
Storage Tips
Leftovers: Cool completely, then refrigerate in an airtight container up to 3 days. The butter will solidify; reheat gently in a non-stick skillet with a splash of water or milk to loosen.
Freezing: Freeze portions in silicone muffin cups, then pop out into a zip-top bag for up to 2 months. Thaw overnight in the fridge and reheat as above. Texture will be slightly denser but flavor remains excellent.
Make-ahead components: Toast walnuts and fry sage up to 3 days ahead; store separately at room temp. Brown the butter the morning of, chill it, then simply re-melt when you boil the gnocchi. You can even pre-grate the Parmesan and keep it in a jar with a pinch of cornstarch to prevent clumping.
