I first heard of pumpkin gnocchi from a friend twenty years ago as she was running down a flight of stairs to catch a train at the Siena station. “How do you make them?” I shouted. “Just mash pumpkin with as little flour as possible so they’ll stick together,” she shouted back. “Some people add a potato, but I don’t.” And with that she was gone.
The idea intrigued me. I love the rich taste of pumpkin, and had just returned from a whirlwind culinary tour of Ferrara and Treviso, where I had tasted several delicious pumpkin dishes – cappellacci con la zucca, pumpkin quiches, torte salate, risotto, budini salati – sometimes combining pumpkin with radicchio or porcini. In Ferrara, I had seen giant, halved, long-necked squash almost as big as guitars already baked available at the supermarket, and was disappointed that I couldn’t carry one of those home on the train. Then a dear friend and expert gardener gave me an eight pound Queensland blue pumpkin, and I decided I should try to make some gnocchi. It sounded so easy. Right?
The first batch I made was, looking back, an amazing success. I simply roasted the pumpkin, mashed it with a bit of flour, added salt, fashioned the gnocchi, dropped them in boiling water. Nothing could have been easier. They came out perfect, and there were tons of them, over ten servings, some of which we gave away and others we froze, and the frozen ones were perfect too.
But it would take years before I obtained similar results again – sweet, rich-flavored gnocchi, brilliant orange and just the right consistency: not pasty, or hard, or mushy. Too much flour makes them indigestible. Not enough and they will dissolve when you drop them in boiling water, or simply turn into unpalatable mush. Different varieties of pumpkins produced widely different outcomes. But after many experiments, I finally hit on a method which works with most varieties of pumpkin/zucche/squash that I have tried. I do find that as a troubleshooting measure, the addition of a baked potato into the mixture is a great help – although purists might disagree.
- So here’s my recipe for those who have asked.
- 1. First, wisely choose your pumpkin/squash. I have found that the best varieties for making gnocchi are pumpkins/squash with a firm, dry pulp, of the “farinoso” ( from farina – “flour”) type. These work well: Zucca lunga napoletana, Zucca di Chioggia, Queensland Blue, Butternut Squash. The classic Mantovana zucca, shaped like Cinderella’s carriage, so readily found in most Italian green grocers, is not as flavorful as the other varieties, but works well in terms of consistency.
- 2. Prepare your pumpkin for roasting/ baking. Cut it into quarters, remove seeds, prick the pulp all over, and roast in a slow oven until the pulp is tender, and the rind has crinkled and shrunk. I use disposable aluminum pans for this as juices from the pumpkin tend to seep out and caramelize, making a bit of a mess. It might take up to 40 mins to 1 hr to roast your pumpkin.
- Pumpkin gnocchi may seem labor intensive, especially the first time you make them. So if you’re ready to keep at it, follow the steps below as given. If not, continue tomorrow or another day: skip down to step 5, put some strained pulp in the fridge for use within 24 hours, or put in freezer for up to 3 months.
- 3. Bake a potato or two. In the meantime, bake a large potato in your microwave. Or 1 medium potato and 1 yellow sweet potato.
- 4. Have some tomato sauce ready.
- 5. Strain the pumpkin Scoop out the pulp into a strainer and let the remaining liquid drain out into a bowl. Keep the liquid to add to soups or sauces. When the pulp has cooled, start squeezing out the pulp with clean hands or cheesecloth. Keep the juice for risotto or soup. You want the pulp to be as dry as possible. 1 kilo of baked pumpkin will probably yield about ½ cup of pulp when properly drained. To make gnocchi for 4, you’ll need between 1-2 cups of pulp (depending on whether you add a potato, or go for the purist version). Strain and squeeze out all your pumpkin, and set aside about 1 + 1/2 cups . Any leftover, strained pulp can be frozen for future use for gnocchi, sauce, soup, risotto, or pumpkin cheese cake, another favorite. See note below on using frozen, squeezed pulp. Or put in fridge for use within 24 hours
- 6. Prepare your mixture Put 1 cup of pumpkin in a bowl, and grate your baked potato and/or sweet potato into the bowl. Add salt to taste and a grind of pepper. Mash together well, and then add 2 tablespoons of cornstarch, then gradually add flour (not more than ¼ x 1 cup of pulp).
- 7. Knead the mixture like bread dough. Flour your hands and begin to knead the mixture. If it feels wet or sticky, add a bit more flour and keep kneading. You’ll know when it’s ready by the way it feels. Your mixture should feel like bread dough. It will be slightly shiny and resistant to the touch. It should not be sticky, or hard and dry, or overly moist. Add another potato and a sprinkling of flour if it feels too wet. But try not to overdo the flour. Cover the gnocchi mixture and let it rest for ten minutes. In the meantime, bring a pot of salted water to boil.
- 8. Test drive your gnocchi. Pinch off a handful of the mixture and roll it out on a floured surface into a long snake, ¾ inch in diameter. With a fork, slice off three or four gnocchi about ¾ of an inch long and drop a couple into the boiling water. Remove them as soon as they float to the surface, and let them dry on a paper towel. Did they keep their shape or did they fall apart?
- 9. Test one with your fork. It should feel firm, but not hard. Now taste it. Is it mushy ( not enough binding element)? Is it pasty (too much flour)? If too pasty, try boiling another one or two just a bit longer to see if a longer boiling time solves the problem. If it still tastes “pasty,” you’ll need to correct the mixture by adding more pumpkin and/ or sweet potato before cooking the rest of the batch.
- On the other hand, your gnocchi might look like they’ve held their shape, but taste very mushy – in which case you’ll need to correct the mixture by adding more flour before cooking the rest. In either case, just put your snake back into the bowl and remix. It sounds complicated, I know, but once you’ve tried it, you’ll soon get the hang of it.
- 10. Fixing the flaws. Too pasty: add some more strained pumpkin pulp that you put aside at the beginning. Too mushy: add a little more flour, a tablespoon of cornstarch, or maybe add a small grated potato, if you didn’t use one. You need to pay attention to the feel of the mixture as you knead it. It really should feel a bit like bread dough. Adjust salt as necessary.
- Or maybe they came out perfect on your first try! Congratulations.
- 11. Roll your mixture into snakes If you are satisfied with the consistency of your gnocchi, divide your mixture into four balls and roll each one out into a snake ¾ inch in diameter. Then with a fork, slice off each gnocchi ¾ inch long.
- 12. Cook the gnocchi in batches of 10 -12. Drop them in the boiling salted water, remove with a slotted spoon as soon as they float to the top, and let them drain in a colander. They shouldn’t stick or clump together, but each one should be individual and “al dente.”
- 13. You can serve them at once, with sage or thyme butter or tomato sauce, with or without cheese. If you have any pulp left over, you can add it to the tomato sauce, or freeze it for future use.
- 14. I like to warm them in the oven as follows.Put some tomato sauce in baking dish, add gnocchi in a single layer, cover with sauce, and top with grated parmesan. Pop them 10-15 minutes in the oven and serve piping hot.
- 15. Interesting additions and variations
- A handful of boiled, squeezed chicory added to the mix will create a lovely green marbled effect and add a bite of contrasting bitter flavor.
- Adding an egg, egg whites, and/or grated cheese, all of which are binding elements, to the mixture before boiling the gnocchi will change the recipe considerably – they become “gnudi” rather than “gnocchi” and will puff up almost twice their size into balls rather than gnocchi. I prefer the gnocchi version, but the gnudi will be relatively foolproof.
- Using frozen pulp Since zucche are often quite large, you may have more pulp than you know what to do with. Roast, strain, and squeeze as indicated and keep up to 3 months in the freezer. Before using frozen pulp for gnocchi, let it thaw out in the fridge. You will need to squeeze it again, however, before making gnocchi, as the thawing process draws out more water. I find that this twice-squeezed pulp will be very flavorful. Wonderful for pumpkin cheese cake. No need to squeeze it again if adding to soup or sauce.
- Freezing gnocchi. Line an aluminum pan with parchment paper. Place gnocchi in pan, slip inside a freezer bag, and freeze for up to 3 months.
