A warm, comforting soup that tastes like autumn in a bowl. Made with butternut squash, apples, and simple pantry ingredients, this slow cooker recipe is naturally creamy, vegan, and perfect for busy weeknights or lazy Sundays.

Ingredients

Scale
  • 1 large butternut squash (about 3 lbs or 1.4 kg), peeled, seeded, and cubed
  • 3 medium apples (about 1 lb or 450g), peeled, cored, and chopped (Honeycrisp or Fuji recommended)
  • 1 large yellow onion, diced
  • 4 garlic cloves, minced
  • 4 cups (960 ml) low-sodium vegetable broth
  • 1 cup (240 ml) full-fat coconut milk
  • 4 sprigs fresh thyme (or 1 teaspoon dried thyme)
  • 1 tablespoon pure maple syrup (or honey)
  • ยฝ teaspoon ground cinnamon
  • ยผ teaspoon ground nutmeg (freshly grated if possible)
  • Salt and black pepper to taste (start with 1 teaspoon salt)
  • Optional garnishes: toasted pumpkin seeds, extra coconut milk or cream, fresh thyme leaves, or a sprinkle of cinnamon

Instructions

  1. Prepare the Squash (15 minutes): Using a sharp chef’s knife, carefully cut the butternut squash in half lengthwise. Scoop out the seeds and stringy pulp with a spoon. Use a vegetable peeler to remove the skin, then cut the flesh into 1-inch cubes. Aim for uniform size so everything cooks evenly. Pro tip: If the squash is too hard to cut, microwave it whole for 2-3 minutes to soften it slightly.
  2. Prep the Apples and Aromatics (10 minutes): Peel, core, and chop the apples into 1-inch pieces. Dice the onion and mince the garlic. Don’t stress about perfectly uniform apple piecesโ€”they’ll all get blended anyway.
  3. Layer in the Slow Cooker (5 minutes): Add the cubed squash, chopped apples, diced onion, and minced garlic to the slow cooker. Pour in the vegetable broth. Add the fresh thyme sprigs, ground cinnamon, ground nutmeg, and a generous pinch of salt and pepper. Give everything a gentle stir to combine.
  4. Cook Low and Slow (6-8 hours on LOW or 3-4 hours on HIGH): Cover the slow cooker and set it to LOW for 6-8 hours or HIGH for 3-4 hours. You’ll know it’s done when the squash is fork-tenderโ€”it should easily pierce with no resistance. Personal note: I prefer cooking on LOW for the full 8 hours. The flavors meld together more deeply, and the squash becomes incredibly silky.
  5. Remove Thyme Sprigs (2 minutes): Once cooking is complete, use tongs to remove the thyme stems. The leaves will have fallen off during cooking, but the woody stems need to go.
  6. Blend Until Smooth (5 minutes): Using an immersion blender, puree the soup directly in the slow cooker until completely smooth and velvety. If using a countertop blender, work in batchesโ€”fill the blender no more than halfway, hold the lid firmly with a kitchen towel, and blend until smooth. Warning: Hot liquid expands when blended. Always vent the lid slightly to release steam.
  7. Add Coconut Milk and Maple Syrup (2 minutes): Stir in the full-fat coconut milk and maple syrup. Taste and adjust seasoningโ€”add more salt, pepper, or a pinch of cinnamon if needed. The soup should be creamy, slightly sweet, and deeply savory.
  8. Serve and Garnish (5 minutes): Ladle the soup into bowls. Drizzle with a swirl of coconut milk or heavy cream, sprinkle with toasted pumpkin seeds, and finish with a few fresh thyme leaves. Serve hot.

Notes

For deeper flavor, sautรฉ the onion and garlic in olive oil before adding to the slow cooker. The soup gets even better after a day in the fridge. If too thick, add extra broth or water; if too thin, cook uncovered on HIGH for 20-30 minutes. For a nut-free version, use oat milk or heavy cream instead of coconut milk. For a lower-carb option, reduce apples to one and add an extra cup of cauliflower florets.
