This creamy Slow Cooker Butternut Squash Soup is silky, cozy, and naturally dairy-free. The slow cooker softens the squash and apples, and the soup is finished with coconut milk and warm spices right at the end so the flavors stay bright. Such a lovely autumn soup!

🍲 While this recipe is perfect as written, it’s incredibly versatile. Add more curry for heat, squeeze in lime for brightness, or top with toasted pepitas for crunch. It’s your soup canvas – paint it however you like!
My 2 Best Tips For Making Slow Cooker Butternut Squash Soup
Quality Curry Powder: Some curry powders have a bitter aftertaste, so looking for a good brand will make a difference in this recipe. Look for blends with vibrant color and strong aroma. I’ve found that McCormick, Simply Organic, and Frontier Co-op are reliable choices and commonly available.
Best Apple Variety: Tart apples like Granny Smith, Braeburn, or McIntosh work best here. They hold their shape during the long cooking process and provide the perfect sweet-tart balance. Avoid softer apples like Red Delicious, which can turn mushy and overly sweet.

The combination of curry powder, garam masala, and turmeric creates an aromatic soup that’s anything but boring!
The coconut milk adds richness without dairy, while the tart apple brings unexpected sweetness that perfectly balances the warming spices.
This soup actually tastes better the next day! Make a big batch on Sunday and enjoy easy lunches all week.
It freezes beautifully for up to 3 months – just remember to leave some headspace in your containers.

Slow Cooker Butternut Squash Soup
Ingredients
- 2 cups vegetable or chicken stock
- 6 cups cubed butternut squash, from a 3–4 lb squash, peeled and seeded
- 1 large tart apple, Granny Smith, Braeburn, or McIntosh, cored and cut into chunks
- 1 large white onion, trimmed, peeled, and cut into large chunks
- 3 cloves garlic, peeled
- 1 can unsweetened coconut milk, canned, 15 ounces
- 1 teaspoon salt, plus more to taste
- 2 teaspoons yellow curry powder
- 1 teaspoon garam masala
- ½ teaspoon turmeric
- ½ teaspoon ground ginger
- ½ teaspoon black pepper
Instructions
- Add stock, squash, apple, onion, and garlic to a 6-quart slow cooker.
- Cover and cook on Low 6–8 hours or High 3–4 hours, until everything is very tender.
- Stir in coconut milk, salt, curry powder, garam masala, ginger, turmeric, black pepper. Blend until completely smooth with an immersion blender right in the slow cooker.
- If the soup is thicker than you like, splash in a bit more warm stock or water.
- Taste and add more salt or curry to make the flavors pop. Ladle into bowls and serve.
Notes
- I moved across the country lately and in restocking some of my spices I bought an extra inexpensive curry powder and I regretted it after the first use. It was extremely bitter and left a really odd aftertaste. Don’t make my mistake, but a reputable brand of curry powder!
- Don’t be stingy with the spices here. Taste and add until it’s to your liking.

Recipe FAQs
No problem! Let the soup cool slightly, then carefully transfer it in batches to a regular blender. Just be sure not to fill the blender more than halfway with hot liquid, and hold the lid down with a kitchen towel. A food processor works too, though you might need to add a bit more stock for the right consistency.
Everything should be fork-tender after the recommended cooking time. The squash should practically fall apart when you poke it, and the onions should be completely soft. If things still seem firm, give it another 30-60 minutes on low.
Sure, but make sure your slow cooker is large enough! This recipe works well in a 6-quart cooker, so doubling it would require at least an 8-quart. The cooking time stays the same, but you might need an extra 30 minutes if your cooker is really full.
