4 tablespoons olive oil, divided
1 large yellow onion, diced
2 medium carrots, sliced
2 celery stalks, chopped
4 garlic cloves, minced
6 cups low-sodium vegetable broth
1 (14.5 oz) can diced tomatoes

1 teaspoon dried thyme
1 teaspoon dried sage
2 cups kale or spinach, roughly chopped
1 teaspoon sea salt
½ teaspoon black pepper
Fresh herbs for garnish (optional)
Directions
- Preheat oven to 425°F. Toss butternut squash and sweet potato with 2 tablespoons olive oil, salt, and pepper. Roast on a baking sheet for 25 to 30 minutes until golden and tender.
- Heat remaining 2 tablespoons olive oil in a large pot over medium heat. Sauté onion, carrots, and celery for 5 to 7 minutes until softened.
- Add garlic, thyme, and sage; cook 1 minute until fragrant.

Make Ahead: You can roast the vegetables up to 2 days in advance. The soup also tastes better the next day as flavors develop.

Step-by-Step Instructions
Step 1: Roast the Root Vegetables
Preheat your oven to 425°F and line a large baking sheet with parchment paper. Toss the cubed butternut squash and sweet potato with 2 tablespoons of olive oil, salt, and pepper until evenly coated.
Spread the vegetables in a single layer, making sure they’re not crowded, which ensures proper caramelization. Roast for 25 to 30 minutes, flipping halfway through, until the edges are golden brown and the pieces are fork-tender.
The roasting process is key to developing deep, sweet flavors. Don’t skip this step or rush it; properly caramelized vegetables make all the difference in the final soup.
Step 2: Sauté the Aromatics
While the vegetables roast, heat 2 tablespoons of olive oil in a large soup pot or Dutch oven over medium heat. Add the diced onion, carrots, and celery, sautéing for 5 to 7 minutes until the onion becomes translucent and the vegetables begin to soften.
Stir in the minced garlic, dried thyme, and sage, cooking for another minute until fragrant. The aromatics should smell earthy and warm, filling your kitchen with cozy fall scents.
Be careful not to burn the garlic; if the pan gets too hot, reduce the heat slightly. This aromatic base builds the foundational flavor of your soup.
Step 3: Build the Soup Base
Pour in 6 cups of vegetable broth and add the can of diced tomatoes with their juices. Stir in 1 tablespoon of maple syrup, which will balance the acidity and enhance the natural sweetness of the vegetables.
Bring the mixture to a boil, then reduce the heat to a gentle simmer. Season with 1 teaspoon of salt and ½ teaspoon of black pepper, adjusting to your taste preferences.
Let the broth simmer for 10 minutes to allow the flavors to meld together. The soup should have a rich, savory aroma with subtle sweet notes.
Step 4: Add the Roasted Vegetables
Once your butternut squash and sweet potato are perfectly roasted, carefully transfer them to the simmering soup pot. Stir gently to incorporate them into the broth without breaking them apart too much.
The roasted vegetables will continue to soften as they simmer, releasing their caramelized flavors into the broth. You should see beautiful contrast between the golden vegetables and the rich tomato-based broth.
Let everything simmer together for 10 to 15 minutes. This allows the flavors to marry and the vegetables to reach the perfect tender consistency.
Step 5: Finish with Greens
Add the chopped kale or spinach to the pot, stirring until the greens wilt into the soup, which takes about 2 to 3 minutes. The greens add fresh color, texture, and an extra boost of nutrients to your harvest soup.
Taste and adjust the seasoning, adding more salt, pepper, or a drizzle of maple syrup if needed. The soup should be well-balanced with sweet, savory, and earthy notes working together harmoniously.
Serve hot in large bowls, garnished with fresh herbs, a crack of black pepper, or a drizzle of olive oil. This soup pairs beautifully with crusty bread or a simple side salad.
Frequently Asked Questions
Can I make this soup in a slow cooker?
Yes! Roast the squash and sweet potato first, then add all ingredients except the greens to your slow cooker. Cook on low for 6 to 8 hours or high for 3 to 4 hours. Add greens in the last 15 minutes.
How do I make this soup creamier?
Blend 2 to 3 cups of the finished soup and stir it back in for a partially pureed texture. Alternatively, add ½ cup of coconut milk or cashew cream at the end for richness.
What other vegetables work well in this recipe?
Try parsnips, turnips, or rutabaga for earthy flavors. Cauliflower, Brussels sprouts, or green beans also work beautifully. Stick to seasonal fall and winter vegetables for the best results.
