Acorn Squash Soup (Rich & Creamy!)

You’ll fall in love with the creamy texture and delicious blend of sweet and savory flavors in my acorn squash soup! Made with roasted acorn squash, rich coconut milk, and fresh herbs, this soup is so comforting and perfect for enjoying with a piece of crusty bread. It’s naturally vegan and gluten-free too!

It’s that time of year when winter squash is popping up at all the farmer’s markets! I find that butternut squash tends to hog the spotlight, and while I love me a good bowl of vegan butternut squash soup, today I want to focus on another super delicious squash variety that you totally should be cooking with: acorn squash.

Jump to:

Acorn squash is super sweet, just like butternut, but it has a slightly different taste, with more nutty notes that work really well when paired up with savory seasonings, which is why we’re using fresh herbs to flavor this soup.

Acorn squash also has a scalloped body, so it’s not as easy to peel as butternut, so we’ll be roasting our squash to make it easier to work with. This also intensifies the flavor of the squash, making for an extra scrumptious soup!

Ingredients You’ll Need

Acorn Squash. Use fully ripe, sweet acorn squash! Good squash can be the difference between a knockout batch of soup and one that’s just…meh. Look for acorn squash with dull skin (not shiny!) that are dark green and orange in color. Your squash should also feel dense and heavy for it’s size.
Olive oil. Other high heat oils like canola, avocado, and corn oil will work just fine in this recipe.
Onion.
Carrots.
Celery.
Garlic.
Vegetable broth.
Fresh rosemary. You’ll need a whole sprig of fresh rosemary for this soup. I don’t recommend substituting dried rosemary, as you just won’t get the same depth of flavor.
Rubbed sage. This is ground up dried sage. It can be found in the spice aisle of most grocery stores.
Coconut milk. Use full-fat coconut milk from a can, and not the type in cartons, which is heavily diluted.
Ground nutmeg.
Salt and pepper.
Pepitas. Also known as pumpkin seeds, these are optional, but make a great topping for acorn squash soup.

How It’s Made

For Acorn Squash Soup halves in the process of having seeds removed with a spoon.

Roasting acorn squash is easy! Cut the squash in half, then scoop out the seeds. Rub the halves with olive oil, place them on a baking sheet, and pop them into the oven. This is the same method we use to make stuffed acorn squash.

Four roasted acorn squash halves on a parchment paper lined baking sheet, one with a spoon scooping out flesh.

The squash are done when they’re tender and browned in spots. Let them cool a bit, then scoop out the inner flesh. This is what we’re using in the soup! The peel can be thrown in the trash or composted.

Tip: Keep an eye on your squash and don’t let them burn. If they have some undercooked spots, that’s okay! Remember, you’ll be cooking them a second time by simmering them in the soup.

Carrots, onion, celery, and garlic cooking in a pot with a wooden spoon.

Heat some olive oil in a pot, then add your diced onion, carrots and celery. Cook this mixture for a bit, just to start softening the veggies. Now add some minced garlic and cook it with the vegetables for about a minute, stirring so you don’t burn it.

Now add your roasted squash to the pot, along with broth, the entire sprig of rosemary, and your rubbed sage. Bring the soup to a boil, then lower the heat and let it simmer for a bit. You can use a spoon to break up any big chunks of squash!

Time to blend the soup! Take the rosemary sprig out first. You can transfer the soup to a blender, like I’ve done, or use a hand blender and blend it right in the pot.

Finish your soup off by adding some coconut milk and nutmeg. It will have cooled down a bit, so reheat it, then season it with some salt and pepper.

Time to enjoy a big bowl of this luscious acorn squash soup! Pepitas make a great topping, but you could also try croutons, nuts, fresh herbs, or even some coconut bacon.

This soup is great with some freshly baked bread. I especially love it with a big chunk of vegan cornbread or a vegan corn muffin.

Variations

Try swapping out the herbs with warming spices like cinnamon, cloves, and ginger. You can keep the nutmeg that’s already in the recipe, as it will go really well with these flavors!
To make curried acorn squash soup, skip the herbs and nutmeg, and season the soup with a couple of teaspoons of curry powder or garam masala.
Add some sweet and tart flavors by adding a Granny Smith apple to the soup!

Frequently Asked Questions

Can I substitute another type of squash?

Absolutely! Obviously, it won’t be acorn squash soup, but this recipe can be made with most varieties of winter squash, such as butternut, kabocha, buttercup, and delicata. Smaller varieties of squash will need less time in the oven, and larger ones will take a bit more.

How can I reduce the calorie content of this soup?

Substituting the coconut milk with light coconut milk will reduce both the fat and calories in this recipe. You can also cut down on the oil used to sauté the vegetables, or use water instead.

How can the sodium content of this soup be lowered?

Most of the sodium comes from the broth. Use reduced sodium broth or replace some of the broth with water!

Leftovers & Reheating

Leftover acorn squash soup will keep in an airtight container in the fridge for three to four days. It will thicken in storage, due to the coconut milk solidifying when chilled. The soup should thin when you reheat it, but feel free to add a splash of water if needed.

You can reheat your soup by microwaving in one minute increments, or by warming it up in a saucepan on the stove over medium heat, stirring frequently.
