Roasted Tomato Basil Soup Cooking Guide

Step 1: Prepare and Roast the Tomatoes and Onion

Preheat your oven to 400°F (200°C). On a baking sheet, toss the halved tomatoes and chopped onion with 2 tablespoons of olive oil, salt, and pepper. Spread them out in a single layer. Roast in the oven for about 30-35 minutes until the tomatoes are soft, slightly caramelized, and the onions are golden.

Step 2: Sauté the Garlic

While the vegetables are roasting, heat a large pot over medium heat. Add a splash of olive oil, then sauté the minced garlic until fragrant, about 1-2 minutes. Be careful not to burn it as garlic turns bitter quickly.

Step 3: Combine Roasted Veggies and Broth

Carefully transfer the roasted tomatoes and onions to the pot with the garlic. Pour in 2 cups of vegetable broth. Bring the mixture to a gentle simmer and let it cook for 10 minutes to marry the flavors.

Step 4: Add Basil and Season

Stir in the chopped fresh basil leaves, salt, pepper, and if using, 1 tablespoon of sugar to balance the acidity. Simmer for an additional 5 minutes.

Step 5: Blend Until Smooth

Using an immersion blender, blend the soup directly in the pot until smooth and creamy. Alternatively, carefully transfer the soup in batches to a countertop blender and puree until velvety.

Step 6: Adjust Consistency and Serve

If the soup is too thick, add a little more broth until you reach your desired consistency. For an extra touch of indulgence, swirl in a splash of heavy cream when serving. Ladle into bowls and garnish with fresh basil leaves or a drizzle of olive oil.

Make It Fit Your Plan

• Make it vegan: Skip the heavy cream, or swap it with coconut cream or a plant-based alternative.
• Low sodium: Use low-sodium broth and adjust salt to taste.
• Spicy kick: Add a pinch of red pepper flakes while sautéing garlic for a little heat.
• Meal prep friendly: Soup keeps well refrigerated for up to 4 days, and freezes beautifully for up to 3 months.
• Pairings: Serve alongside Thyme Bread Loaf or a grilled cheese sandwich for a cozy meal.

Common Errors (and Fixes)

• Soup tastes too acidic: Add a tablespoon of sugar or a splash of cream to balance the flavors.
• Tomatoes not sweet enough: Make sure to roast until caramelized; this step is key to unlocking sweetness.
• Soup too thick: Thin with extra broth or water to reach your preferred consistency.
• Garlic too overpowering: Sauté garlic gently and avoid browning it to keep the flavor mellow.

Keep-It-Fresh Plan

Store leftover soup in an airtight container in the refrigerator for up to 4 days. To reheat, warm gently on the stove over low heat, stirring occasionally. For longer storage, freeze the soup in freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating. If the soup separates after freezing, simply blend again for a smooth texture.

Roasted Tomato Basil Soup Q&A

Can I use canned tomatoes instead of fresh?

Absolutely! Use a good quality canned whole or diced tomatoes. Skip roasting and proceed with sautéing the onion and garlic before adding the canned tomatoes and broth. The flavor will be slightly different but still delicious.

Is it possible to make this soup in a slow cooker?

Yes! Roast the tomatoes and onions as directed, then transfer them to a slow cooker with garlic, broth, and basil. Cook on low for 4-6 hours or on high for 2-3 hours before blending.

How can I make this soup creamier without using heavy cream?

You can stir in coconut cream, cashew cream, or even a dollop of plain yogurt (if you tolerate dairy). Another option is to blend in cooked potatoes or white beans for natural creaminess.

What’s a good side dish to serve with this soup?

This soup pairs wonderfully with crusty bread like the Thyme Bread Loaf, grilled cheese sandwiches, or a fresh garden salad for a balanced meal.
