Why You’ll Love This Vegan Butternut Squash Soup Recipe
This creamy miso butternut squash soup is a seasonal favorite: rich and silky, yet light enough to be part of a balanced meal. Roasting the squash brings out a deeper sweetness while aromatics—onion, garlic, and herbs—build savory layers. Non-dairy milk adds smoothness and miso introduces savory umami plus fermented goodness. The result is a satisfying vegan soup that’s both comforting and nourishing.
How to Roast Butternut Squash
Halve the squash lengthwise, remove the seeds, and place it cut-side down on a baking sheet. Roasting with the skin on makes the flesh easier to scoop out once tender. For extra flavor, brush the cut surface with a little neutral oil and sprinkle with salt and pepper. Roast at 400°F (200°C) for 30–40 minutes, until a fork slides in easily.
Ingredient Notes & Substitutions
- Butternut squash: The base of the soup—naturally sweet and creamy when roasted. Swap with pumpkin or sweet potato if preferred.
- Miso paste: Adds savory depth. White miso is mild and slightly sweet; red miso is stronger and saltier. Use what you enjoy and check labels if you need gluten-free miso.
- Vegetable stock: Use low-sodium broth to control salt levels or homemade stock for more flavor.
- Non-dairy milk: Adds creaminess. Full-fat coconut milk or oat milk creates a richer texture.
- Onion & garlic: Build the aromatic base. Shallots or yellow onion can be used instead of white onion.
- Herbs: Fresh thyme, rosemary, and sage are ideal; dried herbs work in a pinch.
Optional Toppings
- Extra virgin olive oil or sesame oil drizzle
- Roasted hazelnuts or other toasted nuts
- Crispy chickpeas or croutons
- Fried sage leaves
- Microgreens or a dollop of vegan yogurt
- Sesame seeds or dukkah for crunch

How to Make Creamy Butternut Squash Soup
Step 1: Preheat the oven to 400°F (200°C). Halve the squash, remove seeds, brush with neutral oil, and season with salt and pepper. Roast cut-side down for 30–40 minutes until fork-tender. Let cool and scoop out the flesh.
Step 2: Measure 2–3 cups of roasted squash for the recipe.
Step 3: In a large pot, heat a few teaspoons of neutral oil over medium heat. Sauté sliced onion until soft and translucent. Add minced garlic and fresh herbs; cook another 1–2 minutes without browning.
Step 4: Add the roasted squash to the pot and briefly sauté. Pour in vegetable stock, bring to a boil, then reduce heat and simmer, loosely covered, for about 8 minutes to let flavors meld.
Step 5: Remove from heat. Blend the soup with miso paste and non-dairy milk until completely smooth—either in a high-speed blender or with an immersion blender. Adjust texture with more stock or plant milk as needed.
Step 6: Taste and season with salt and pepper if necessary.
Step 7: Serve hot with a drizzle of olive oil or sesame oil and your choice of crunchy garnishes like toasted hazelnuts or fried sage.
Secrets to Success
- Roast the squash with the cut-side down to develop caramelized, sweet flavor.
- Use a non-stick baking mat or parchment for easy cleanup.
- Start with white miso if you prefer a gentle umami note; try red miso for a deeper, saltier taste.
- Add a little fresh ginger if you like a warming, spicy edge.
- If short on time, roast the squash in an air fryer for faster results.
Serving Tips
This soup is smooth and velvety, so contrast is key. Add crunchy or bright elements to balance the texture and flavor. Consider croutons, crispy chickpeas, toasted nuts, microgreens, or a swirl of vegan yogurt. A small drizzle of toasted sesame oil adds a nutty finish.
Storage Tips
Fridge: Cool completely, then store in an airtight container for up to 5 days. Stir before reheating.
Freezer: Freeze in freezer-safe containers or reusable bags, leaving room for expansion. The soup will keep for up to 3 months.
Reheating: Thaw overnight in the fridge and warm on the stove over medium heat, stirring occasionally. Add a splash of vegetable stock or plant milk if the soup has thickened. For a quick option, reheat in the microwave, stirring every minute until hot.
