This recipe for acorn squash soup is smooth, delicious, and perfectly seasoned. It’s the perfect cozy meal to enjoy during cooler weather.
The squash is cooked with vegetables, spices, and broth, then blended into a silky smooth soup you’ll want to devour by the bowl.
If you’ve never cooked with acorn squash, this recipe is a perfect introduction and I’ll show you how below.
What is an Acorn Squash
Acorn squash is a winter vegetable similar to butternut squash in flavor and texture but slightly more fibrous. It’s shaped like an oversized acorn with dark green skin, hence the name.
Simple Acorn Squash Soup
This acorn squash soup is buttery-sweet and savory with notes of curry and chili spices. The addition of milk makes it extra creamy, and when pureéd it achieves a rich consistency that easily glosses the back of your spoon.
Here’s everything you need to make acorn squash soup:
- red onion and celery: these are known as aromatic vegetables and cook together with spices and butter.
- butter: to sauté the veggies.
- all-purpose flour: added to the veggies and helps give the soup a thicker consistency, also optional.
- dill: a dried herb with a bright flavor and slightly similar taste to anise.
- curry powder: a blend of earthy, warm spices.
- paprika: it’s smoky and pairs well with the flavors of acorn squash and curry.
- vegetable broth: the liquid component to this soup recipe.
- milk: enhances the smooth texture and makes this soup more creamy.
- acorn squash: the star ingredient of the recipe.
To make this soup dairy-free use coconut milk instead of regular milk to keep the creamy flavor and a neutral oil to sauté the veggies.
How to Pick Out an Acorn Squash
To pick out an acorn squash that’s ripe and ready to cook, check for firm skin that’s a dark shade of green. You’ll also notice a small patch of bright orange on one side, from where the squash sat on the ground, but if the entire squash is covered in orange, it’s past its prime. The stem should also be attached and slightly withered and brown.
How to Cook Acorn Squash in the Microwave to Soften
This soup calls for 2 cups steamed and mashed acorn squash, about 1 whole squash. Steaming the acorn squash in the microwave will help soften and make blending with the rest of the ingredients easier.
You can steam the acorn squash before cooking the soup, follow the steps below and refrigerate in a container or zip bag for up to 3 days.
First, you’ll rinse the squash with water and pat dry with a clean kitchen towel. Microwave on high for 5 minutes.
Remove the squash from the microwave and allow to cool off before cutting in half. Use a large spoon to remove the seeds from the center of the squash.
Place 1 of the squash halves onto a plate and microwave for 8 minutes or until the squash is fork-tender. Repeat with the second half.

How to Make Acorn Squash Soup
Once the squash is pre-cooked, you’re ready to move on to the rest of the recipe.
In a large saucepan, melt the butter over medium heat. Add the onion and celery and sauté until softened. Add the flour, dill, curry, chili powder, and paprika. Stir to coat the veggies.
- Add the liquid ingredients
Stir in the chicken broth and milk. Bring the mixture to a boil and cook for 2 minutes.
- Blend until smooth
Add the squash, salt, black pepper, and stir to combine. Using an immersion blender, blend until smooth. Alternatively, working in batches, transfer the soup to a high-speed blender and process until smooth.
How to Puree Soup
Immersion blenders aren’t the only way to pureé soups. You can also use a regular blender, although it does require a few extra steps. Since we will be blending hot soup, you want to take extra precautions not to burn yourself or splatter the kitchen. Here’s how to puree soup in a blender:
- Remove the soup from heat and cool for a few minutes. *You don’t want it boiling.
- Remove the center cap from the lid of your blender.
- Use a large measuring cup to transfer the soup to the blender, filling it halfway.
- Top the blender container with the lid and place a towel over the open space.
- Blend until smooth.
- Transfer the soup to an empty pot.
- Repeat with the remaining soup
Once the soup is smooth and creamy, you can return it to medium heat and bring it to a simmer before serving.
Acorn Squash Soup Consistency
Acorn squash soup is on the creamy side and slightly thicker than butternut squash soup. Steaming the squash in the microwave and pureeing in a blender certainly help to achieve this consistency, but the squash itself has a buttery texture that makes it ideal for blended soups.
Acorn Squash Soup Toppings
Adding a few topping ideas will certainly take this soup to the next level. Here are a few additions to sprinkle over the top of your bowl:
- cooked and chopped bacon
- grated Parmesan cheese
- crème fraîche

How to Store Leftovers
This acorn squash soup is good for up to 4 days in the fridge. Otherwise, the rest will need to be frozen. Thankfully, this pureed soup is perfect for freezing and reheating. Since many of the ingredients are blended down, its texture and flavors won’t be altered.
To freeze, you’ll want to bring the soup to room temperature before transferring it into gallon-size zip bags. I like to place the bags filled with soup onto a baking sheet so they freeze flat. Once they’re frozen solid, you can remove the baking sheet and stack them in the freezer.Print
