I love making this hearty vegetable soup on weekends when the pace slows down.

Each spoonful feels like a hug from the inside, especially when paired with a slice of rustic bread or a warm roll.

Ingredients

For the Soup Base

• 2 tablespoons olive oil
• 1 large onion, diced
• 3 cloves garlic, minced
• 3 medium carrots, peeled and chopped
• 2 celery stalks, chopped
• 1 medium sweet potato, peeled and cubed
• 1 small butternut squash, peeled and cubed
• 1 zucchini, chopped
• 1 red bell pepper, chopped

For the Broth

• 6 cups vegetable broth
• 1 can (14 oz) diced tomatoes
• 1 teaspoon dried thyme
• 1 teaspoon dried rosemary
• 1 bay leaf
• Salt and freshly ground black pepper, to taste

Optional Add-Ins

• 1 cup chopped kale or spinach
• 1 can (15 oz) cannellini beans or chickpeas, drained and rinsed
• 1 tablespoon lemon juice (adds a bright finish!)

Ingredient Notes

• Olive oil – I always use extra virgin olive oil for that rich, fruity flavor—it makes the soup feel extra cozy.
• Sweet potato & butternut squash – Don’t skip either! They give the soup its natural sweetness and body.
• Vegetable broth – I recommend a low-sodium version so you can control the seasoning. It really lets the vegetables shine.
• Diced tomatoes – Adds a touch of acidity to balance the sweetness of the squash and carrots.
• Kale or spinach – Stir in at the very end to keep it bright and fresh; it’s a little extra boost of fall greens.
• Beans – Optional but highly recommended. They make the soup more filling and hearty—perfect for a harvest soup.

Kitchen Equipment Needed

• Large Soup Pot or Dutch Oven – Perfect for sautéing and simmering all those veggies in one pot. I love my Le Creuset; it heats evenly and looks gorgeous on the stove.
• Wooden Spoon or Silicone Spatula – For stirring without scratching your pot. I always reach for my trusty wooden spoon—it feels like an extension of my hand!
• Chef’s Knife – For chopping all the vegetables quickly and safely. A sharp knife makes this part so much easier.
• Cutting Board – Essential for prepping your veggies. I keep a sturdy bamboo board for everyday chopping.
• Measuring Cups & Spoons – To get the seasonings and broth just right. Accuracy here makes a big difference.
• Ladle – For serving the soup into bowls without spilling. Bonus points if it’s deep and sturdy.

Instructions

1. Prep Your Vegetables

• Wash, peel, and chop all your vegetables: carrots, celery, sweet potato, butternut squash, zucchini, and bell pepper.
• Mince the garlic and dice the onion.
  Pro Tip: Try to cut vegetables into similar-sized pieces so they cook evenly.

2. Sauté the Aromatics

• Heat 2 tablespoons of olive oil in a large soup pot over medium heat.
• Add the onion and garlic, stirring occasionally, until fragrant and translucent, about 3–4 minutes.
• Toss in the carrots and celery, sautéing for another 4–5 minutes until slightly softened.
  Pro Tip: Don’t rush this step—softening the vegetables first builds a deeper flavor for your soup.

3. Add the Heartier Vegetables

• Stir in the sweet potato, butternut squash, zucchini, and red bell pepper.
• Cook for 2–3 minutes, allowing the vegetables to mingle and start releasing their flavors.

4. Pour in the Broth and Seasonings

• Add 6 cups of vegetable broth and the can of diced tomatoes.
• Stir in thyme, rosemary, bay leaf, salt, and pepper.
• Bring the soup to a gentle boil over medium-high heat.

5. Simmer Until Tender

• Reduce the heat to low and cover the pot.
• Let the soup simmer for 25–30 minutes, or until all the vegetables are tender when pierced with a fork.
  Pro Tip: Taste the broth halfway through and adjust seasoning as needed—it’s easier to tweak gradually than at the end.

6. Add Greens and Optional Beans

• Stir in chopped kale or spinach and your drained beans if using.
• Simmer for an additional 5–7 minutes, just until the greens are wilted and beans are warmed through.

7. Finish and Serve

• Remove the bay leaf and stir in a tablespoon of lemon juice for a bright, fresh finish.
• Ladle into bowls and serve hot.
  Pro Tip: Pair with crusty bread or a sprinkle of parmesan for extra comfort and flavor.

Tips and Tricks for Success

• Prep Ahead – Chop all your vegetables before you start cooking; it makes the process smooth and stress-free.
• Even Sizing Matters – Cut veggies to similar sizes so everything cooks evenly and nothing turns mushy.
• Season Gradually – Add salt and pepper in stages to avoid over-seasoning. Taste as you go!
• Layer Flavors – Sautéing aromatics first and simmering slowly brings out the depth of this harvest soup.
• Adjust Consistency – Prefer a thicker soup? Mash some of the cooked vegetables with a spoon or use an immersion blender for a creamier texture.

Ingredient Substitutions and Variations

• Butternut Squash – Swap for pumpkin or acorn squash for a slightly different sweet note.
• Sweet Potato – Yukon gold or regular potatoes work well if you don’t have sweet potatoes.
• Vegetable Broth – Chicken broth can be used if you’re not keeping it vegetarian.
• Beans – Any cooked beans (like kidney or black beans) can replace cannellini beans.
• Greens – Spinach, Swiss chard, or even collard greens are excellent alternatives to kale.
• Herbs – Fresh thyme and rosemary can be swapped for dried basil or oregano if that’s what you have on hand.

Serving Suggestions

• I love serving this autumn vegetable soup with a slice of crusty sourdough bread—it’s perfect for dipping and soaking up every last bit of broth.
• Pair it with a simple side salad of arugula and apple slices; the crispness balances the warmth and heartiness of the soup beautifully.
• Top each bowl with a sprinkle of grated Parmesan or a drizzle of olive oil for an extra layer of richness.
• For a cozy dinner, serve alongside a warm grilled cheese sandwich—the combination is unbeatable on a chilly evening.
• Add a few crunchy roasted pumpkin seeds on top for texture and a subtle nutty flavor; it’s my little autumn twist!

Storage and Reheating Instructions

• Refrigerator – Store soup in an airtight container for up to 4 days. It tastes even better the next day as the flavors meld together.
• Freezer – Freeze in individual portions for up to 3 months. Thaw overnight in the fridge before reheating.
• Stovetop Reheat – Warm gently over medium heat, stirring occasionally until heated through.
• Microwave – Heat in a microwave-safe bowl for 2–3 minutes, stirring halfway for even heating.
• Tip – If soup thickens too much after storing, add a splash of vegetable broth or water to loosen it up while reheating.
