Ingredients for Creamy Vegan Roasted Tomato Basil Soup

Gather these simple, wholesome ingredients to create your soup. Don’t worry—most are pantry staples!

Main Ingredients

• 2 lbs (900g) ripe tomatoes: Roma or vine-ripened tomatoes work best for roasting. You can also use a mix of heirloom varieties for extra flavor.
• 1 large onion: Yellow or sweet onion, chopped.
• 4 garlic cloves: Minced for a robust flavor.
• 2 tbsp olive oil: For roasting and sautéing.
• 4 cups (950ml) vegetable broth: Low-sodium for better control over seasoning.
• 1/2 cup (75g) raw cashews: Soaked in hot water for 15 minutes to soften (or use 1 can of full-fat coconut milk for a nut-free option).
• 1/4 cup (10g) fresh basil leaves: Plus extra for garnish.
• 1 tbsp tomato paste: Enhances the tomato flavor.
• 1 tsp salt: Adjust to taste.
• 1/2 tsp black pepper: Freshly ground for the best flavor.
• 1/2 tsp smoked paprika: Optional, for a subtle smoky note.
• 1 tbsp balsamic vinegar: Adds a touch of acidity to balance the sweetness.

Optional Add-Ins

• 1 carrot: Diced and roasted with the tomatoes for natural sweetness.
• 1 celery stalk: Adds depth to the soup base.
• 1 tsp red pepper flakes: For a spicy kick.
• 1/4 cup (60ml) coconut cream: For extra richness (stirred in at the end).

Step-by-Step Instructions

1. Roast the Tomatoes and Vegetables

Roasting is the secret to this soup’s deep, complex flavor. Here’s how to do it:

• Preheat your oven to 400°F (200°C).
• Wash and dry the tomatoes, then slice them in half lengthwise. Place them cut-side up on a baking sheet lined with parchment paper.
• Drizzle the tomatoes with 1 tbsp olive oil and sprinkle with 1/2 tsp salt and 1/4 tsp black pepper.
• Add the chopped onion and garlic to the baking sheet (and carrot/celery if using). Toss them lightly in oil and spread them out in a single layer.
• Roast for 30-35 minutes, or until the tomatoes are soft and slightly charred at the edges. The onions should be golden and caramelized.

2. Sauté the Aromatics

While the vegetables roast, prepare the base for your soup:

• In a large pot, heat 1 tbsp olive oil over medium heat.
• Add the tomato paste and cook for 1-2 minutes, stirring constantly, until it darkens slightly. This step enhances the umami flavor.
• Pour in 1 cup of vegetable broth and stir to deglaze the pot, scraping up any browned bits. This adds depth to the soup.

3. Blend the Soup

Now, it’s time to transform the roasted vegetables into a silky-smooth soup:

• Once the vegetables are done roasting, transfer them to the pot with the tomato paste and broth. Add the remaining 3 cups of vegetable broth.
• Bring the mixture to a gentle simmer and cook for 5 minutes to let the flavors meld.
• Drain the soaked cashews (or add the coconut milk) and add them to the pot along with the fresh basil, balsamic vinegar, and smoked paprika (if using).
• Use an immersion blender to blend the soup until smooth. If you don’t have an immersion blender, carefully transfer the soup to a countertop blender in batches and blend until creamy. Be sure to vent the lid to allow steam to escape!

4. Adjust and Serve

Taste your soup and adjust the seasoning as needed:

• Add more salt or pepper to taste.
• For extra richness, stir in coconut cream or a drizzle of olive oil.
• Garnish with fresh basil leaves, a swirl of coconut cream, or a sprinkle of red pepper flakes for heat.

Tips for the Best Vegan Tomato Basil Soup

Follow these pro tips to ensure your soup is creamy, flavorful, and foolproof every time:

1. Choose the Right Tomatoes

For the best flavor, use ripe, in-season tomatoes. Roma tomatoes are meaty and low in moisture, making them ideal for roasting. If fresh tomatoes aren’t available, you can substitute with 2 cans (28 oz each) of whole peeled tomatoes. Roast them on a baking sheet for 20 minutes to concentrate their flavor before blending.

2. Soak the Cashews Properly

Cashews are the key to this soup’s creamy texture. For the smoothest results:

• Soak raw cashews in hot water for at least 15 minutes to soften them. This ensures they blend smoothly and don’t leave a gritty texture.
• If you’re short on time, boil the cashews for 10 minutes to speed up the process.
• No cashews? Use canned full-fat coconut milk for a nut-free alternative. It won’t be as neutral in flavor, but it will still be deliciously creamy.

3. Roast for Maximum Flavor

Don’t skip the roasting step! Roasting the tomatoes and onions caramelizes their natural sugars, adding a depth of flavor that raw or canned tomatoes can’t achieve. For extra smokiness, broil the vegetables for the last 2-3 minutes of roasting.

4. Blend Until Ultra-Smooth

For the creamiest texture, blend the soup until it’s completely smooth. If you’re using a countertop blender, let the soup cool slightly before blending to avoid pressure buildup. Strain the soup through a fine-mesh sieve if you prefer an ultra-silky texture (though this is optional).

5. Balance the Flavors

Tomato soup can sometimes taste too acidic or sweet. Here’s how to balance it:

• Too acidic? Add a pinch of sugar or a splash of maple syrup to round out the flavors.
• Too sweet? A splash of balsamic vinegar or lemon juice will add brightness and balance.
• Too bland? Boost the flavor with a pinch of smoked paprika, a dash of nutritional yeast, or an extra clove of garlic.

6. Make It Ahead

This soup tastes even better the next day as the flavors have time to meld. Store it in an airtight container in the fridge for up to 4 days or freeze it for up to 3 months. Reheat gently on the stove, adding a splash of broth or water if the soup is too thick.

Nutritional Benefits of Vegan Tomato Basil Soup

Not only is this soup delicious, but it’s also packed with nutrients that support overall health. Here’s a breakdown of its key benefits:

1. Rich in Antioxidants

Tomatoes are one of the best sources of lycopene, a powerful antioxidant linked to reduced risk of heart disease and certain cancers. Cooking tomatoes (like in this soup) actually increases the bioavailability of lycopene, making it easier for your body to absorb.

2. Supports Heart Health

The combination of tomatoes, garlic, and olive oil in this soup is a heart-healthy trifecta. Garlic has been shown to lower cholesterol and blood pressure, while olive oil is rich in monounsaturated fats that support cardiovascular health.

3. Boosts Immunity

This soup is loaded with vitamin C (from tomatoes and basil) and zinc (from cashews), both of which play a key role in immune function. Garlic also has natural antimicrobial properties that help fight off infections.

4. Anti-Inflammatory Properties

Basil contains eugenol, a compound with anti-inflammatory effects that may help reduce chronic inflammation. The olive oil in this recipe also contains oleocanthal, which has been compared to ibuprofen in its ability to reduce inflammation.

5. Low in Calories, High in Fiber

With just ~150 calories per serving (without bread), this soup is a light yet satisfying meal. The fiber from the vegetables and cashews helps keep you full and supports digestive health.

Serving Suggestions

This creamy vegan tomato basil soup is delicious on its own, but it’s even better with a few tasty accompaniments. Here are some ideas to elevate your meal:

1. Classic Pairings

• Vegan Grilled Cheese: Use dairy-free cheese and whole-grain bread for a nostalgic combo.
• Garlic Bread: Toast slices of baguette with olive oil, garlic, and parsley for dipping.
• Crusty Bread: A warm loaf of sourdough or ciabatta is perfect for soaking up every last drop.

2. Toppings and Garnishes

• Fresh Herbs: Sprinkle with chopped basil, parsley, or chives.
• Creamy Swirl: Drizzle with coconut cream or cashew cream for extra richness.
• Crunchy Croutons: Toss cubes of bread with olive oil and herbs, then bake until crispy.
• Spicy Kick: Add a dash of hot sauce or red pepper flakes.

3. Meal Prep Ideas

• Lunch Jars: Layer the soup with cooked quinoa, chickpeas, and spinach in a mason jar for a portable meal.
• Freezer Meals: Portion the soup into freezer-safe containers for quick, healthy lunches.
• Soup and Salad Combo: Pair with a simple green salad or roasted vegetable salad for a balanced meal.

Frequently Asked Questions

Can I make this soup without a blender?

While a blender is ideal for achieving a creamy texture, you can make this soup without one. After roasting the vegetables, mash them with a potato masher or fork until they’re mostly smooth. The texture won’t be as silky, but it will still be delicious. For extra creaminess, stir in coconut milk or blended silken tofu at the end.

Is this soup gluten-free?

Yes! This recipe is naturally gluten-free, as long as you use gluten-free vegetable broth and check that any add-ins (like tomato paste) are certified gluten-free. Serve with gluten-free bread or crackers for dipping.

Can I use canned tomatoes instead of fresh?

Absolutely! Canned tomatoes are a great shortcut, especially when fresh tomatoes are out of season. Use 2 cans (28 oz each) of whole peeled tomatoes, drained and roasted for 20 minutes to enhance their flavor. San Marzano tomatoes are a premium choice for their sweet, low-acid taste.

How can I make this soup oil-free?

To make this soup oil-free, skip the olive oil and roast the vegetables on a parchment-lined baking sheet without oil. Sauté the onion and garlic in a splash of vegetable broth instead of oil. The soup will still be flavorful, though the texture may be slightly less rich.

Can I add other vegetables to this soup?

Yes! This soup is very versatile. Try adding:

• Roasted red peppers: Adds a sweet, smoky flavor.
• Zucchini or eggplant: Roast with the tomatoes for extra heartiness.
• Spinach or kale: Stir in at the end for a nutrient boost.
• Sweet potato: Roast with the tomatoes for natural sweetness and creaminess.

How do I store and reheat leftovers?

Store leftover soup in an airtight container in the fridge for up to 4 days. To reheat, warm it gently on the stove over medium-low heat, stirring occasionally. If the soup is too thick, add a splash of broth or water to thin it out. You can also freeze the soup for up to 3 months. Thaw it in the fridge overnight before reheating.
