Oh, you know you want this in your life….a super delicious side dish recipe (that happens to be healthy) with little hands on time! Savory, cozy fall vibes in every bite. As far as acorn squash recipes go, it doesn’t get any better than this!

I’m obsessed over here! This easy squash recipe is ridiculously tasty. There’s more of a subtle, earthy sweetness than you find with butternut squash recipes. And I’m not complaining.

I love the savory, authentic fall flavors in this acorn mash….it’s right up there with my Vegan Stuffed Acorn Squash Recipe , or balsamic roasted root veggies in terms of cozy and satisfying.

This roasted and mashed acorn squash is a staple in our house this time of year with good reason. Fall always seems to be a bit hectic and I just love the simplicity of this recipe. Get it into the oven and then forget about it while you move on to other tasks. Once the squash and garlic are roasted, the dish comes together in about 2 minutes, with staples from your spice cabinet. That’s it. No mess, no fuss.

Is Acorn Squash Healthy?

Mashed Acorn Squash Recipe - Debra Klein (8)
  • Acorn squash (like many of the other winter squash varieties—and you can sub most of them in this recipe: butternut, kabocha, pumpkin, etc) is loaded with health benefits.
  • High in antioxidants that fight free radical damage.
  • High amounts of beta-carotene and vitamin C that helps skin stay bright and staves off wrinkles.
  • Boosts the immune system, and contributes to decreased inflammation.
  • High in fiber, supporting healthy digestion.
  • Mashed acorn squash is a tasty and nutrient dense choice for those watching their weight as well.

  • Savory acorn squash is a wonderful fall dish that balances out all the sweet stuff so prevalent this time of year.

Ingredients and Substitutions:

Mashed Acorn Squash Recipe - Debra Klein (10)
  • Acorn Squash: It has a beautiful orangy-yellow color and and a nutty flavor when roasted. It’s easy to use and nutrient dense. Substitute any hard winter squash like butternut, pumpkin, kabocha or hubbard in this recipe. Delicata squash will take only 20 minutes to become tender. Spaghetti squash won’t become smooth and creamy, so save that as a vessel for vegan bolognese sauce.
  • Olive oil: Just a bit adds to the flavor and texture. If you’re oil free, just rub a bit of water over the cut side and then season before roasting. Omit the oil when mashing and if it’s too dry, add a Tablespoon of plant milk to help make your mash creamy.
  • Garlic: This is the ingredient that makes this recipe so tasty, in my opinion. The garlic will soften in both texture and taste as it roasts, making it perfect to mash right into the squash.
  • Cinnamon: The illusion of sweet goes hand in hand with cinnamon…and I think the illusion is just the right amount of sweetness for this savory recipe. Substitute with a pinch of nutmeg.
  • Cumin: Possibly my favorite spice. Cumin increases antioxidant intake, promotes digestion and provides some iron. All that and it tastes great too.

How to cut an Acorn Squash:

For this recipe, you don’t need to peel the acorn squash. Yay!! You will need to cut it in half though and that is most safely done when the squash can be stable on a cutting board.

Before attempting to cut the squash in half, cut a thin sliver off the non-stem end so it will sit flat on the cutting board, without moving around. Then, use a sharp knife to cut through the stem all the way to the bottom.

Once the squash is halved, use a spoon to scoop out the seeds. A grapefruit spoon with serrated edges makes this easy to do…and also will help remove any stringy bits.

How to Roast

Now that your squash is halved and the seeds removed, it’s ready to roast. Line a rimmed baking sheet with parchment paper for easy clean up. Preheat the oven to 375 degrees.

Drizzle the insides and cut parts of the squash with olive oil and sprinkle with sea salt and freshly ground black pepper. Place cut side up on the prepared pan. Add the garlic cloves STILL IN THEIR PAPER SKINS to the baking tray.

An acorn squash that is about 2 pounds will take about 45 minutes to roast until tender. If you can easily stick a fork into the squash, you know it’s done.

Once it’s cool enough to handle, scoop the flesh out and into a large mixing bowl. This should be easy to do with a large spoon.

Once all the acorn squash pulp is in the bowl, you’re ready to add garlic, spices and mash!

Mashed Acorn Squash Recipe - Debra Klein (16)
  1. Scoop roasted acorn squash pulp into a bowl.
  2. Add roasted garlic to the roasted squash. Gently squeeze the end of the garlic clove and the pulp will come right out of the papery skin.
  3. Use a potato masher to incorporate garlic and squash together into a smooth and uniform puree.
  4. Sprinkle the cinnamon, cumin, cayenne and salt to squash mixture. Continue to mash/mix until spices have been evenly dispersed. Taste for seasoning and add more of what you desire.

BAM….just like that you have a healthy side dish recipe that took no time to make. I like to garnish with a bit more freshly ground black pepper and then sprinkle with some sliced scallions, or fresh herbs like parsley, sage or oregano.

Meal Prep and Storage

  • How to store: Store in an airtight container in the refrigerator. Vegan mashed squash will stay good in the fridge for up to a week or freezer for 6 months.
  • How to reheat: Mix well and reheat in baking dish in a preheated 350 degree oven for 20 minutes, or until heated through. Garnish with fresh sliced green onions or fresh herbs.
  • How to freeze: Cool completely and transfer to freezer safe zip top bag that has been labeled and dated. Push out any air and seal completely. Lay flat in the freezer. Thaw in fridge, transfer to baking dish and mix well before reheating. If squash is a bit watery when it defrosts, stir in 1 teaspoon arrowroot powder before reheating.

Debra’s Pro Tips

Mashed Acorn Squash Recipe - Debra Klein (18)
  • Not all acorn squash are the same size. Taste for seasoning and add more if your squash was particularly large.
  • Don’t skimp on the garlic. Keep the garlic from burning by using large cloves and don’t toss in the oil. No fresh garlic? I’m sorry, but it happens….use a teaspoon of garlic powder (not garlic salt) to season the mash.
  • Make this recipe YOURS. I gravitate towards the svory, but if sweet is your thing, swap out the cumin for a pinch of nutmeg and the cayenne for some allspice. Then add a swirl of maple syrup instead.
  • If you don’t have/can’t find acorn squash, make this recipe with kabocha, butternut, hubbard, or whatever hard winter squash you do have. Delicata squash will work well, but they’re small, so you will need 4-5. In a pinch, use sweet potatoes.
  • Make it into an acorn squash puree for a bold plating statement. It will look fabulous underneath any roasted vegetable. (I’m thinking oven roasted broccoli). Instead of mashing the roasted acorn squash by hand, put it all in a blender or food processor and add 2 Tablespoons veggie broth or plant milk.

What else can you do with this dish?

  • Use it to top this vegan shepherd’s pie.
  • Make some veggie spring rolls and place a spoonful on the wrapper before placing the veggies in.
  • Put a large scoop (or whatever you have left) into a pot of cauliflower leek soup before you puree.
  • Make waffles. Use this recipe for leftover mashed potato waffles and insert the mashed squash instead of the mashed potatoes.
  • Use it to replace the pumpkin puree in this overnight oats recipe.
  • Make it a bowl. Include a variety of raw veggies (greens, chopped cabbage, radicchio), cooked veggies, grains and some leftover mashed squash. Drizzle on the apple/walnut dressing from my fall harvest salad recipe…and you’re in for a real treat.

Recipe FAQs

Do you have to peel acorn squash before cooking?

No peeling required for acorn squash. You can halve and remove seeds, then roast. When it’s tender, just scoop out the flesh and mash. You can also slice it and roast with the skins on…they’re edible, so make sure to give it a good wash before beginning.

How long to bake squash at 350?

I like to bake my squash in a preheated 375 oven. For squash halves, it will take about 40 minutes until tender. If you’re slicing and baking the squash, about 20 minutes is all you need.

How do you thicken mashed squash?

Roasted squash shouldn’t need any thickener, unless you’ve added liquid-which I don’t recommend. If you’ve boiled the squash and the mash is watery, try adding 1-2 teaspoons of arrowroot powder or ground flax. Alternately, be sure to drain the squash well and even pat dry before mashing. Better yet, roast it instead of boiling to avoid watery mash.

Why is my acorn squash watery? ›

To avoid watery acorn squash, do not over cook it. Overcooked squash will become watery and mushy. Salting the squash before roasting it also helps to pull out some of the moisture to avoid watery squash.

What happens if you don't blanch squash before freezing? ›

Summer squash, like most vegetables, must be blanched before they can be frozen. Blanching stops enzyme actions that can cause loss of flavor, color and texture. Blanching works best if you heat 1 gallon of water to boiling in a large pot fitted with a wire basket or colander.

Can you freeze acorn squash without blanching? ›

You may decide to blanch the squash before you freeze it if you're worried about the taste, texture, color, and nutrients staying intact, but it is truly unnecessary, and the vegetable will last just as long whether you complete this extra tedious step or not.

Is there a difference between roasting and baking squash? ›

Most recipes say to either bake or roast butternut squash—but what's the difference? While both cooking methods will turn the tough, raw gourd into a soft, sweet ingredient, roasting butternut squash is the more common process for achieving browned, crispy edges and a creamy interior.

How do you cut acorn squash too hard? ›

The first and most important thing to have on-hand is a very sharp chef's knife or a longer, thick utility knife. Lay the squash on it's side. Raise a knife 3-4 inches above the squash and give it a little chop to break into it. Using your other hand, press down on the top of the blade and slice all the way through.

What if a squash is too hard to cut? ›

The best way to soften any squash is to roast it to n the oven. I slice butternut squash in half lengthwise, scoop out the seeds, and put the halves face down on an oiled baking sheet. Roast at 375°F until a knife slides easily into the meat of the squash, 45 minutes to an hour, depending on the size of the squash.
