Walk into any grocery store in October and you’ll see them. Those weird, lumpy, multicolored gourds taking up space in big wooden bins. Most people grab a Butternut or maybe an Acorn squash if they’re feeling adventurous, but the world of types of squash is actually massive. It’s a botanical rabbit hole.
Honestly, we’ve been eating these things for about 10,000 years. Indigenous peoples in Central and South America were cultivating the "Three Sisters"—corn, beans, and squash—long before Europeans arrived. Squash served as the "living mulch," its massive leaves shading the soil to keep moisture in and weeds out. It’s a brilliant system. But today, we mostly just stare at a Hubbard squash and wonder if we need a literal chainsaw to open it. (Spoiler: Sometimes you do).
Why Summer and Winter Squash Aren't Actually Different Seasons
This is the big one. People think "summer" and "winter" refer to when the plant grows. That’s wrong. All squash grows in the summer. The real difference is when you pick it and how long it lasts on your counter.
Summer varieties, like Zucchini or Yellow Crookneck, are picked when they're babies. Their skin is thin, the seeds are soft, and you can eat the whole thing raw if you want to. They’re basically the impatient teenagers of the garden. If you leave a zucchini on the vine too long, it turns into a giant, woody baseball bat that tastes like nothing.
Winter squash is a different beast. Farmers let these sit in the field until the vine literally dies and the skin becomes a hard, protective armor. This "curing" process is what allows a Spaghetti squash to sit in your pantry for three months without rotting. It’s nature’s own Tupperware. Inside that armor, the sugars concentrate, which is why your roasted Butternut tastes like candy while a summer squash stays mild and watery.
The Heavy Hitters You Probably Already Know
Butternut Squash (Cucurbita moschata)
You know this one. It looks like a beige lightbulb. It’s the gold standard for a reason: the ratio of flesh to seed is incredible. Unlike the Acorn squash, which is half-empty, the Butternut has a long, solid neck of pure orange goodness. It’s sweet, nutty, and gets incredibly creamy when blended. If you’re making soup, this is your guy.
Acorn Squash
Small, green, and shaped like—well, an acorn. The ridges make it a total pain to peel, so don't even try. Just slice it in half, scoop the seeds, and roast it with butter and maple syrup. The skin is technically edible, but it stays a bit tough. It’s a bit more "fibrous" than Butternut, so it holds its shape better if you’re stuffing it with quinoa or sausage.
Spaghetti Squash
This is the weirdo of the group. When you cook it, the insides don't turn into mash. They pull apart into long, translucent strands. It’s become the darling of the keto and gluten-free world, but don't expect it to taste like Barilla. It tastes like squash. It’s crunchy and mild. Pro tip: cut it into rings instead of halves if you want longer "noodles."
The Weird Ones That Taste Better Than They Look
Ever seen a Blue Hubbard? It looks like a dusty, blue-grey alien pod. It can weigh 20 pounds. You might need a mallet to get into it. But inside? Some of the best-tasting squash meat on the planet. It’s why high-end pie companies often use Hubbard instead of actual pumpkin.

Then there’s the Kabocha. This is a Japanese staple. It looks like a squat, dark green pumpkin with some white stripes. The flesh is incredibly dense—almost like a cross between a sweet potato and a chestnut. The best part? The skin is thin enough to eat after roasting. No peeling required. It’s a game-changer for weeknight dinners.
Delicata is another "lazy cook" favorite. It’s striped, oblong, and often called the "sweet potato squash." Because the skin is so thin, you just slice it into half-moons and toss them in the oven. It caramelizes beautifully. Honestly, if you see these at the market, buy three. They disappear fast because they're so easy to prep.
The Pumpkin Identity Crisis
Here is a fun fact to annoy your friends at dinner: All pumpkins are squash, but not all squash are pumpkins.
The classic Jack-o'-lantern (the Connecticut Field pumpkin) is actually pretty terrible for eating. It’s watery, stringy, and bland. If you want to make a pie from scratch, you want a Sugar Pie Pumpkin or a Cinderella Pumpkin (Rouge Vif d'Etampes). These are smaller, denser, and have a much higher sugar content.
And that canned pumpkin puree you buy? It’s almost never the orange pumpkin you see on Halloween. Most of the time, it’s a variety called Dickinson squash. It looks more like a tan, elongated Butternut than a classic pumpkin. The FDA is actually pretty chill about labeling; they allow several types of firm-fleshed golden squash to be labeled as "pumpkin."
How to Not Waste Your Money
Shopping for types of squash requires a bit of a "thump test."
- Check the Stem: A dried, woody stem means the squash was harvested at full maturity. If the stem is missing, bacteria can get in, and the squash will rot faster.
- The Weight Factor: Pick it up. It should feel heavy for its size. If it feels light or "hollow," it’s likely drying out inside.
- The Skin: For winter squash, you want a matte finish. If it’s shiny, it was probably picked too early and won't be as sweet. Avoid soft spots or "bruises" like the plague—those turn into mold overnight.
- The Sound: Give it a flick with your finger. A ripe winter squash should give you a dull "thud."
Nutrition and Why Your Body Cares
We talk a lot about the flavor, but squash is a nutritional powerhouse. That bright orange color isn't just for show; it’s loaded with beta-carotene, which your body converts to Vitamin A. It’s also packed with Vitamin C, potassium, and magnesium.
Because it’s high in fiber but relatively low in calories, it’s one of the best "volume" foods you can eat. You can eat a massive bowl of roasted Delicata for the same caloric hit as a small handful of crackers. Plus, the complex carbs in winter squash provide a steady burn of energy rather than the spike-and-crash you get from refined grains.
Real-World Kitchen Advice
Stop boiling your squash. Please.
When you boil squash, you're just diluting the flavor and making it mushy. Roasting is the only way to go. High heat ($400^{\circ}F$ or $200^{\circ}C$) triggers the Maillard reaction, turning those natural sugars into something complex and savory.
If you're dealing with a particularly hard squash, like a Hubbard or a large Butternut, don't risk your fingers. Microwave the whole thing for 2-3 minutes first. This softens the skin just enough to make your knife glide through instead of sticking. And keep the seeds! Just like pumpkin seeds, you can roast the seeds of almost any winter squash with a little salt and smoked paprika for a great snack.
Beyond the Roast: Other Ways to Use Squash
- Grate it: Raw summer squash or zucchini can be grated into salads or slaw.
- Fry the flowers: Squash blossoms are a delicacy. Stuff them with ricotta, dip them in a light batter, and fry them for 30 seconds.
- Puree for baking: Use roasted Butternut or Kabocha puree in place of oil or applesauce in muffins and breads to add moisture and a nutrient boost.
- The Peel: If you’re roasting Delicata or Kabocha, leave the skin on. It adds a nice texture and saves you ten minutes of frustration.
Actionable Next Steps
Instead of grabbing the same old zucchini this week, try these three things to master the world of squash:

- Swap Your Potato: Next time you're planning on mashed potatoes, try a 50/50 mix of potatoes and roasted Kabocha squash. You get a deeper color and a more complex flavor profile without much extra work.
- The "Two-Week" Rule: If you buy a winter squash, let it sit on your counter for a week or two before eating. Many varieties, like the Honeynut (a tiny, concentrated Butternut), actually get sweeter as they sit and "cure" further at room temperature.
- Freeze the Excess: If you find a great deal on Butternut or Hubbard, peel and cube it, then freeze it on a flat tray before bagging it. These cubes can go straight from the freezer into soups or stews all winter long.
Experimenting with different varieties isn't just about nutrition. It's about breaking the monotony of the standard grocery store rotation. Each variety has a specific moisture content and sugar level that changes how it reacts to heat. Start with a Delicata because it’s the "entry-level" easy squash, then work your way up to the monsters like the Blue Hubbard. Your kitchen (and your palate) will be better for it.
