When the weather turns cooler, the produce aisle starts to look a little different. Vibrant berries and summer vegetables make way for apples, root vegetables, hearty greens—and an array of colorful winter squash.
With their hard outer shells and rich, naturally sweet flesh, winter squash varieties are some of the season’s most versatile ingredients. They can be roasted, puréed into soup, stuffed, mashed, blended into sauces, or simply served as a side dish.
And while you may already have a favorite—hello, butternut—there are plenty of varieties worth getting to know.
Despite the name, winter squash are generally harvested in late summer and fall and are known for their ability to keep for weeks or even months when stored properly. Unlike tender summer squash such as zucchini, winter squash have mature seeds and a firm outer rind. Common varieties include butternut, acorn, delicata, kabocha, spaghetti, and Hubbard squash.
Winter squash are also a natural fit for seasonal eating. IIN has long emphasized the value of connecting with the foods available in a particular season and region. Winter squash are among the produce commonly available during fall and winter, and their hearty texture makes them especially well-suited to roasting, soups, stews, and other warming meals.
From a nutrition perspective, winter squash can contribute dietary fiber, potassium, vitamin C, and a variety of carotenoids. Their bright orange and yellow colors are often a clue that they contain provitamin A carotenoids such as beta-carotene. The body can convert some of these carotenoids into vitamin A, an essential nutrient involved in normal vision, immune function, and cell growth.
And perhaps one of their biggest benefits? They're incredibly easy to turn into satisfying, nourishing meals.
If you're new to winter squash, butternut is a great place to start.
Recognizable by its elongated, bell-like shape and pale tan skin, butternut squash has smooth, orange flesh with a mildly sweet, nutty flavor. When roasted or cooked, it becomes creamy and tender, making it particularly versatile.
Why it's nutritious
Butternut squash is rich in carotenoids, including beta-carotene, which the body can convert to vitamin A. It also contributes fiber, potassium, and vitamin C.
Because vitamin A supports normal vision and immune function, incorporating colorful vegetables such as winter squash into a varied eating pattern can be one way to increase intake of important plant-based nutrients.
How to choose it
Look for a butternut squash that:
A few superficial scratches aren't necessarily a problem—the important thing is that the squash itself feels firm and intact.

Coach-friendly pairing: Add chickpeas or lentils and a handful of greens to turn this side dish into a satisfying grain bowl.
Acorn squash gets its name from its distinctive shape, which resembles—you guessed it—an acorn. Its dark green exterior sometimes has patches of orange or yellow, while the flesh is golden-orange and slightly sweet.
Unlike butternut squash, acorn squash is particularly well suited to being stuffed and roasted in its shell.
Why it's nutritious
Acorn squash provides dietary fiber and potassium, along with vitamin C and carotenoids. Like other colorful winter squash, it can contribute provitamin A carotenoids to the diet.
Its edible seeds are also worth saving. Clean and roast them with a little olive oil and seasoning for a crunchy snack or salad topping.
How to choose it
Choose an acorn squash that:
Don't worry if the exterior isn't perfectly uniform. Natural variation in color is normal.

Make it your own: Swap farro for quinoa or brown rice, use spinach in place of kale, or add white beans or lentils for additional plant-based protein.
Delicata might be the most approachable squash on this list.
It has a long, cylindrical shape with cream-colored skin and green or orange stripes. Its flesh is tender, sweet, and slightly nutty—and unlike many other winter squash, the thin skin is edible.
That means there's no peeling required.
Why it's nutritious
Delicata squash provides fiber, vitamin C, potassium, and carotenoids. Its colorful flesh contributes plant compounds to the diet, while its edible skin adds additional texture and fiber.
And from a practical perspective, the fact that you don't have to peel it makes delicata an especially convenient choice for busy weeknight cooking.

Look for delicata squash that:

Coach-friendly tip: This recipe is easy to adapt. Swap arugula for spinach, lentils for chickpeas, or pumpkin seeds for walnuts based on what's available and what you enjoy.
Sometimes called Japanese pumpkin, kabocha squash has a dark green, often mottled exterior and bright orange flesh.
The texture is one of its biggest draws: dense, creamy, and almost velvety when cooked. Its flavor is sweet and nutty, making it delicious both in savory dishes and alongside warming spices.
Why it's nutritious
Kabocha is another colorful winter squash that can contribute carotenoids, including provitamin A carotenoids, as well as fiber, vitamin C, and potassium.
The specific nutrient composition varies among squash varieties and preparation methods, so rather than focusing on one “superfood” nutrient, think of kabocha as one colorful option within a diverse plant-forward eating pattern.
How to choose it
Select kabocha that:

Coach-friendly pairing: Serve alongside beans, lentils, tofu, chicken, or another protein source to create a more complete meal.
Spaghetti squash is the outlier in this group.
Instead of becoming creamy when cooked, its flesh separates into long, spaghetti-like strands. It's mild in flavor and makes a fun base for sauces, bowls, and other meals.
It can be particularly useful for someone who wants to experiment with adding more vegetables to familiar dishes without completely abandoning the foods they already love.
Why it's nutritious
Spaghetti squash provides fiber, vitamin C, potassium, and other micronutrients while adding volume and variety to meals.
It also demonstrates an important nutrition lesson: healthy eating doesn't have to mean replacing every familiar food with something completely different. Sometimes it's about experimenting with new ingredients and discovering what you genuinely enjoy.
How to choose it
Choose spaghetti squash that:

Hubbard squash may look intimidating—and that's part of its charm.
Large, irregularly shaped, and often blue-gray, green, or orange on the outside, Hubbard squash has dense orange flesh with a rich, sweet flavor. Because of its size and tough skin, it's often easier to cut it into large pieces and roast rather than trying to peel it raw.
Why it's nutritious
Like other winter squash, Hubbard squash can provide fiber, potassium, vitamin C, and carotenoids. Its deep orange flesh is a reminder that eating a variety of colorful plants can help bring a broad range of nutrients and phytonutrients into the diet.
How to choose it
Look for a Hubbard squash with:
Because Hubbard squash can be quite large, don't be afraid to buy a portion that's already been cut and wrapped if your grocery store offers it.

One of the best things about winter squash is that you don't necessarily have to use it right away.
Whole, uncooked winter squash can generally be stored in a cool, dry place such as a pantry or countertop. USDA guidance recommends choosing squash with a firm outer shell and storing it in a cool, dry location.
Once cut, however, squash should be refrigerated and used within an appropriate timeframe.
If you have more squash than you can eat, cooked squash can also be incorporated into soups, sauces, grain bowls, muffins, and other recipes—or frozen for later use.
And don't forget about the seeds! Many winter squash seeds can be cleaned, seasoned, and roasted for a crunchy snack or topping.
For Health Coaches, winter squash can be more than a conversation about nutrients. It's an opportunity to help clients explore what healthy eating looks and feels like in their actual lives.
Instead of telling a client, “You should eat more vegetables,” consider questions such as:
This approach shifts the conversation from prescribing a perfect diet to helping someone discover sustainable behaviors that fit their preferences, culture, schedule, budget, and lifestyle.
That's especially relevant when exploring seasonal foods. There isn't one “right” way to eat winter squash—or one variety that's inherently better than another.
Maybe a client loves creamy butternut squash soup. Maybe they discover they love the crispy edges of roasted delicata. Maybe spaghetti squash makes dinner more enjoyable because it gives them a new way to eat a favorite sauce.
The goal isn't to make someone eat a particular food. It's to help them build a more nourishing relationship with food that works for them.
