Acorn Squash Soup

This easy Roasted Acorn Squash Soup is a cozy and creamy soup that’s perfect for a cold night.

To get the most amazing flavor from your squash, roast it with onions and garlic first!

Roasting brings out the best in just about any vegetable, and when it comes to acorn squash, roasting is the only way I’d recommend cooking it.

While you could technically boil or steam acorn squash, you really need to cook it in the oven on high heat to properly pull out its nutty, earthy, and sweet flavor.

Just like making butternut squash soup, once your squash has been properly roasted, you’ll just need to simmer it in broth for a few minutes, then add it to the blender. You’ll have a smooth, flavorful acorn squash soup ready in no time!

You will learn how easy it is to roast acorn squash, and then you can try my cheesy stuffed acorn squash recipe! It’s filled with savory ground chicken stuffing.

Ingredients In Acorn Squash Soup

Here’s what you need to make this amazing roasted veggie soup:

Complete list of ingredients and amounts can be found in the recipe card below.

• Acorn Squash: When you’re shopping, look for squash that are heavy for their size. Fresh acorn squash won’t have any wrinkles or soft spots, and they should have a dull, matte exterior. I’m using these striped acorn squash today, but feel free to pick up the regular dark green ones.
• Carrots: When roasted, carrots add a wonderful sweetness. They also keep the color of this soup bright and vibrant.
• Onion and Garlic: To keep things simple, we’ll cook these in the oven along with the squash. There’s no need to dice or mince them, just cut both the onion and the whole garlic bulb in half.
• Olive Oil: You will need oil to properly roast the veggies, and olive oil adds a wonderful richness.
• Seasonings: There is so much flavor in roasted acorn squash, you will only need salt, pepper, and a bay leaf to season this soup.
• Vegetable Stock: I make homemade veggie stock or vegetable broth in my Instant Pot all the time! Use your own homemade stock, or pick up a good quality variety at the store.
• Sour Cream: This is optional if you’re trying to keep this recipe dairy free, but otherwise, I definitely recommend it to add a slight tang and creamy texture.

To Prep the Veggies for Roasting

Peel the carrots, slice the onion, garlic bulb, and acorn squash in half, and remove the seeds from the squash.

How To Make Roasted Acorn Squash Soup

First, let your oven preheat to 400°F (200°C).

2. Roast: Place the vegetables, cut side up in a roasting pan or on a baking sheet. Drizzle with olive oil, sprinkle with salt and pepper, and roast for 20 minutes.

1. Flip, and Continue Roasting for 20 or 25 more minutes, or until the squash is tender.

1. Scoop the flesh out of the acorn squash, and remove the peels from the garlic and onion.
2. Simmer. Add the roasted veggies to a large pot with vegetable stock and a bay leaf. Simmer for 10-15 minutes to meld the flavors together.

1. Blend: Add the soup to a blender with sour cream and blend until smooth and creamy.

Recipe Tips

• Slicing the Squash. In an ideal world, you’ll have a large, sharp knife and an acorn squash with easy-to-cut skin. Often, that’s not the case though! If your squash is too hard to cut in half, poke holes in it and pop it in the microwave for a minute or 2 until it’s soft enough to cut.
• Roasting the Squash. If you need any more details about how to roast acorn squash, I have a whole post on the topic.
• Instead of Sour Cream, try this recipe with heavy cream, half and half, or coconut cream instead. Any of these will impart a rich, creaminess, just in slightly different ways.
• Blending. I love my Vitamix Blender. It’s the perfect tool for creating rich and creamy soups. This recipe will work with a less powerful blender, but the texture will be a bit more rustic. Try it with a stick blender too!

Storing Tips

First, I highly suggest that you try to have leftovers. This soup tastes even better the next day once the flavors have fully developed!

Keep leftover acorn squash soup in an airtight container in the fridge for tup to 4 days.

This soup also freezes quite well for up to 3 months. I like to freeze individual portions and pull them out when I’m in the mood for a comforting, cozy bowl of soup.

What To Serve With Acorn Squash Soup

First, think about adding some garnishes to your bowls. A creamy, slightly sweet soup like this one will pair beautifully with crunchy, salty things like homemade croutons, toasted pepitas, or soup crackers.

Fresh parsley would also be delicious here!

This soup can be enjoyed on its own, or as an appetizer or starter for a larger, heartier meal. Consider pairing acorn squash soup with roast chicken, grilled steak, or baked salmon.

Recipe FAQs

Can I make this with other types of squash?

You can use any type of winter squash variety to make soup! Try this method with butternut, buttercup, delicata, or kabocha squash.

How do you cut acorn squash for soup?

Before you roast the acorn squash, cut it in half lengthwise. Use a spoon to remove the seeds and it’s ready to go! You could technically cut the squash into smaller pieces and it would roast more quickly, but it’s not really necessary.

Can you freeze acorn squash soup?

Yes, this soup freezes extremely well. Freeze individual portions in freezer bags or containers for up to 3 months.
