In this blog post, we’ll explore the world of roast vegetables for soup, discuss the best vegetables to use, and share a delicious roasted vegetable soup recipe that you can make at home.

Selecting and Preparing Vegetables for Roasting

To create a delicious roasted vegetable soup, it’s essential to choose the right vegetables. Some of the best vegetables to roast for soup include:

1. Root vegetables (e.g., carrots, potatoes, sweet potatoes)

2. Squash (e.g., butternut, acorn)

3. Onions and garlic

4. Tomatoes and bell peppers

5. Cruciferous vegetables (e.g., cauliflower, broccoli)

When selecting vegetables, look for fresh, high-quality produce. Preparing the vegetables for roasting involves washing and peeling (if necessary), cutting them into even-sized pieces, and tossing them in oil and seasoning.

Roasting Techniques and Tips

The key to perfectly roasted vegetables is choosing the right oil. Olive oil is a popular choice for roasting vegetables, as it adds a rich flavor and has a reasonably high smoke point. However, other high smoke point oils such as vegetable oil, canola oil, or avocado oil are also suitable.

Season your vegetables with simple salt and pepper or experiment with different herbs, spices, and specialty seasoning blends to create unique flavor profiles. We recommend roasting your vegetables at a temperature of 400°F (200°C) to 425°F (220°C) for even cooking and caramelization. Roasting time will vary depending on the type and size of the vegetables, so keep an eye on them and test for tenderness with a fork.

To ensure even roasting, avoid overcrowding the pan and stir or flip the vegetables halfway through the cooking time. Using two sheet pans can also help prevent overcrowding and ensure a single layer of vegetables on each pan.

Turning Roast Vegetables into Soup

Once your vegetables are roasted to perfection, it’s time to turn them into a delicious roasted veggie soup. First, choose a base for your soup. Vegetable or chicken stock is a popular choice and keeps the soup light, while cream or milk can be added for a richer, creamier texture.

Blend the roasted vegetables using an immersion blender, standard blender, or food processor. Adjust the blending time to achieve a smooth or chunky texture, depending on your preference. Next, add additional flavor elements, such as fresh herbs, spices, seasonings, or acidic elements like lemon juice or vinegar. Adjust the consistency of your soup by adding more broth, water, or cream as needed. Finally, taste your soup and adjust the seasoning with salt and pepper to taste.

Serving Ideas and Accompaniments

A beautiful garnish can elevate your roasted vegetable soup to the next level. Consider topping your soup with a swirl of cream or yogurt, a sprinkle of toasted nuts or seeds, or a few fresh thyme leaves.

Accompany your soup with a crusty bread, a grilled cheese sandwich, or a simple green salad for a complete and satisfying meal. If you’re in the mood for a side dish, try pairing your soup with a delicious gluten-free option like roasted sweet potato or red bell pepper.

Now that you’re familiar with the basics of roast vegetables for soup, it’s time to try your hand at a tasty recipe. This roasted vegetable soup recipe is absolutely delicious, nutritious, and perfect for meal prep or a cozy dinner at home.


– 2 large carrots, roughly chopped

– 1 large sweet potato, roughly chopped

– 1 butternut squash, peeled, seeded, and roughly chopped

– 1 red bell pepper, roughly chopped

– 1 large red onion, roughly chopped

– 4 garlic cloves, peeled

– 3 tablespoons olive oil

– Salt and pepper to taste

– 4 cups vegetable stock (or chicken stock for a non-vegetarian option)

– 1 can diced tomatoes, drained

– 1 can coconut milk

– 1 teaspoon fresh thyme leaves

– Optional garnishes: fresh thyme, a swirl of coconut milk, toasted nuts or seeds


1. Preheat the oven to 425°F (220°C). Place the chopped vegetables and garlic cloves on a large baking tray lined with parchment paper. Drizzle with olive oil, and season with salt and pepper. Toss to coat the vegetables evenly.

2. Roast the vegetables in the preheated oven for 25-30 minutes, or until they are tender and slightly caramelized. Remove from the oven and let them cool slightly.

3. In a large pot, heat 1 tablespoon of olive oil over medium heat. Add the roasted vegetables and saute for 2-3 minutes, until they are heated through and slightly softened.

4. Add the vegetable stock (or chicken stock), diced tomatoes, and coconut milk to the pot. Stir to combine, and bring the mixture to a simmer.

5. Using an immersion blender (or carefully transferring the soup to a regular blender in batches), blend the soup to your desired consistency. If you prefer a chunkier soup, blend for a shorter time. For a smoother soup, blend longer.

6. Taste the soup and adjust the seasoning, adding salt and pepper as needed. Stir in the fresh thyme leaves and simmer for an additional 5-10 minutes.

7. Serve the soup warm, garnished with your choice of toppings. If you’re storing the soup for meal prep, let it cool completely before transferring it to airtight containers and storing it in the refrigerator.
