What Does Tromboncino Squash Taste Like?

The short answer (and short is the wrong word for this gargantuan squash) is that tromboncino tastes phenomenal as a summer squash and just ok as a winter squash.

Tromboncino, also known as zucchetta rampicante and Tromba d’Abenga (Albenga is a city on the Italian Riviera where tomboncino originates) is a cultivar of  Cucurbita moschata, a constellation of squashes that includes butternut squash. Trombonchino, as far as I know, is the only or one of the few squashes in the Cucurbita moschata family that is harvested as a summer squash

Tromboncino as winter squash.

I think of tromboncino as the new zucchini. It has a sweeter flavor than zucchini and the long neck is always free of seeds. As a winter squash it’s passable, but somewhat bland. If you’ve got the room to let this thing sprawl (ours is over 25 feet long) you’ll find it more productive than zucchini. I planted seeds in April, transplanted the seedlings in May and in early November I still have squash on the vine.

Like all squash it benefits from copious amounts of nitrogen and compost. We grew ours in straw bales. I’ve heard that it’s resistant to squash borers (not a problem I’ve had, so I can’t speak from experience). The seeds came from Franchi via the Heirloom Seed Store.

  1. We grew it for the first time this year and probably won’t grow it again. It was entertaining, but we didn’t think much of the taste in either iteration. We’re giving it away now, in fact. We’ll save the space for the butternuts we love next year.

  2. I’ve never grown it, but when I was a member of a CSA it was a frequent inclusion in the basket. I liked it better than zucchini (and I love zucchini). The farmers grew the squash on hugh trellises, so the necks were long, straight, and seed-free. It was noticeably less watery than other summer squash. I’ve never eaten it in its mature state. Vine borers are the bane of Curcurbita in my neck of the woods, so if I ever get a larger growing space I’ll give it a try.

  3. I’ve grown Tromboncino a zillion (or maybe a zillion and 1) times. I totally agree about your flavor recommendations. We make winter squash sculptures every fall and I can highly recommend these for expanded creative possibilities. Grown on the ground, they make great curved spider legs with a giant pumpkin. Grown on a trellis, where you get your maximum yardage, they are straight and make excellent giant wiener dogs.

  4. We grew them for the first time this year and plan to grow it in next year’s garden, too. We grew them up a trellis and they were very happy. We ate most of them young and only have 2 we hardened off to try as winter squash.

  5. I agree that the flavor is not that much to write home about. Although it is prolific and easy to grow, I didn’t like it nearly as much as other zucchini varieties or other winter squash varieties. For me, that’s a deal breaker. I want to grow things for great flavor, so I switched back to growing different summer and winter squashes.

  6. Oh! I grew this for the first time this summer too. I found the flavor as a young summer squash horrible. It tasted like green pumpkin. I’ve let the rest grow out to adulthood…and like others I have so many I’m giving them away. As a winter squash it’s edible but not special. I give it kudos for abundance and for beating out the pest pressure that most of my other squash succumb to. But, next year I will grow and accept the inevitable quick death of the varieties I find delicious. To me one green tint patty pan fruit and one long pie pumpkin fruit are worth more than dozens of troms.

  7. I let many of mine grow to maturity. I canned them and dried them. The canned ones I have used in soups. They are particularly good pureed with garlic, etc. and put into bean soup. The dried slices are also great in soups.

  8. We grow Tromboncino every year. Sliced thin and steamed, served with butter and salt, it is a zuke replacement in our house. Also, slice paper thin and coat with olive oil then spices and bake for chips.

    This squash likes a trellis, the squash grow long and straight. You can save seed from this one very successfully.

    It is resistant to the vine borers, they are horrible here. The borers will riddle this vine but it keeps growing and growing. I usually have to pick baby squash (great taste) in November before the hard frost.

  9. I grew Tromboncino one year. I have never had so much squash. It was unbelievably productive. And I don’t remember having much trouble with insect pests with it. I didn’t know it can also be a winter squash, so I never left them on the vine long enough to try it that way.

  10. Here in the southeast, trombocino’s resistance to squash vine borer is what makes it such a winner. I can.not.grow other types if summer squash organically. Trombocino is such a champ that even if a svb bores into the vine, it will keep on ticking. Compare that to every other summer squash variety that I’ve tried that just dies after the first brush with svb. Long live the wonderful Trombocino!

  11. I bought my seeds from pinetree looking for a Korean squash that had similar leaf and shape. It turned out to be a Italian heirloom squash that took over my boyfriend’s garden. I was amazed how big and prolific they got. I wasn’t impressed with the taste but with the abundance I had to think fast what I can do with it. I got into canning when I found a zucchini salsa recipe on line. Since then I modified the recipe to include Trinidad Scorpions to make some really hot salsa. I’ve been doing this for past three years canning and selling salsas thanks to this wonderful zucchini. This venture have included my hot pineapple salsa, curry relish, zapple strudels, and zapple cake. All thanks to this wonderful zucchini.

  12. Thanks for the information. I’m the only person I know who has ever grown this and this is my first year trying it. I planted it because it is a moschata, and we have a HORRIBLE squash vine borer problem in this part of the country, and I have not got so much as a blossom on my summer squash for over seven years – until now! So far it has not succumbed and now, at last, I’m getting back to having that old problem you won’t know you love until you don’t have it anymore: What to do with all this squash! :D

    Oddly enough, I am finding that the fruits on mine are growing completely straight, even the ones on plants that aren’t climbing the fence yet. Also, I am finding the taste and texture of mine (in the immature version, anyway) to be more like eggplant than squash – in fact I’ve started using it in all my eggplant recipes. Did I get some kind of weird cultivar or something? In any case, I’m really glad to have discovered it!

    • Interesting–squash does outcross very easily so it is possible you have some kind of mutant. Speaking of mutants, our tromoboncino reseeded itself and is taking up a third of our backyard. I’ve been using them in their immature form this summer and have found them to be much tastier than their mature form.

  13. I have grown them in Oxford, England, for a few years now and love them. I will also grow them in New Zealand when I finally return there.
    They are great croppers and I use them at all stages of their growth.
    They are great to use in pasta dishes, curries, sliced on the bbq, fritters, and many other ways.
    If I have surplus I either give them to friends, or to my local Italian restaurant, and Alberto uses them in many of his dishes, and in pickles ! Bravo, Bravo ! :)
