ABOUT THIS RECIPEA Sheet Pan of Contrasts
Refrigerated or vacuum-packed gnocchi can go straight into the oven. Without parboiling, they develop a golden-brown exterior while staying soft inside, as long as you toss them with oil and leave plenty of space on the baking sheet. For fresh gnocchi, follow the package instructions; some varieties are more delicate and cook faster. Divide the ingredients between two baking sheets if they’re crowded on one. A full baking sheet traps steam and gives you fewer crispy edges.
Broccoli stands up well to high heat. Cut the florets to roughly the same size, and use the peeled stem too, sliced thinly. It has a firm bite and roasts in the same time as the florets. The dark spots are just what you want: they bring a roasted, slightly nutty flavour that goes well with the butter and Parmesan. Broccoli is available year-round; in the Netherlands, field-grown broccoli is generally available from June through November.
The lemon butter is tossed with the gnocchi and broccoli only after roasting. This keeps the butter from burning on the hot baking sheet and lets the lemon flavour stay bright. Zest the lemon before squeezing it, and add the juice gradually: the butter should taste fresh, not overwhelmingly sour. Chilli flakes add a gentle heat. Leave them out or use less if you prefer a milder meal.
Hazelnuts complete the contrast: they’re crunchy and rich in flavour alongside the soft gnocchi and buttery sauce. If using unroasted nuts, toast them in a dry pan, let them cool and roughly chop them. Almonds are a good alternative. For a vegetarian version, choose Parmesan made with vegetarian rennet; the cheese adds salt and umami, so taste before adding extra salt.
Serve the dish straight away, while the gnocchi are still crisp. A simple green salad with a tangy dressing goes well alongside, but you don’t need it to make this a complete meal. Store leftovers covered in the fridge and use within two days. Reheat them in a frying pan with a small splash of oil; the microwave will soften the gnocchi and make them lose their crisp exterior.
