Step‑by‑Step Instructions for Homemade Roasted Tomato Basil Soup
Step 1: Roast the Tomatoes and Garlic
Preheat your oven to 400°F (200°C). Halve the Roma or plum tomatoes and place them cut-side up on a parchment-lined baking sheet. Nestle the garlic cloves among the tomatoes, then drizzle everything with olive oil, and season with salt and pepper. Roast for 40-45 minutes until the tomatoes are caramelized and the garlic is tender and fragrant, filling your kitchen with inviting aromas.
Step 2: Caramelize the Onions
While the tomatoes are roasting, heat 2 tablespoons of olive oil in a large pot over medium heat. Add the sliced yellow onions and stir occasionally, allowing them to cook for about 20-30 minutes. You’re looking for a golden brown color and a sweet aroma, which will create a delicious base for your Homemade Roasted Tomato Basil Soup.
Step 3: Blend the Ingredients
Once your tomatoes and garlic have cooled slightly, transfer them into a blender or food processor. Add the caramelized onions, fresh basil leaves, and dried oregano for added depth of flavor. Blend everything together until the mixture is completely smooth. If your blender struggles, add a splash of broth or water to help it along, making sure your soup is as silky as possible.
Step 4: Simmer the Soup
Pour the blended mixture back into the pot over medium heat. Gradually stir in the vegetarian broth or water, adjusting the amount to achieve your desired soup thickness, whether you prefer it creamy or more broth-like. Season with salt and pepper to taste, and let the soup simmer for about 10 minutes, allowing the flavors to meld together beautifully.
Step 5: Serve
Once simmered, it’s time to serve your delightful Homemade Roasted Tomato Basil Soup. Ladle the soup into bowls and garnish with fresh basil leaves or a sprinkle of Parmesan cheese, if desired. Pair it with crusty bread or a grilled cheese sandwich for an extra comforting meal, bringing warmth and satisfaction with every bite.

Roasted Tomato Basil Soup Recipe FAQs
How do I select the best tomatoes for this soup?
Absolutely! For the best flavor, choose ripe Roma or plum tomatoes. Look for ones that are slightly firm but yield a bit when gently pressed. Avoid any with dark spots or wrinkles, as these may indicate overripeness. Fresh, garden-grown or organic tomatoes will enhance the overall taste, making your Roasted Tomato Basil Soup even more delectable.
How should I store leftovers of the soup?
Very simple! Allow any leftover Roasted Tomato Basil Soup to cool completely before transferring it to an airtight container. It will keep well in the refrigerator for up to 4-5 days. Just make sure to store it in a moisture-free environment to maintain its creamy texture.
Can I freeze the soup for later?
Yes! Freezing is a fantastic option if you’re looking to enjoy the soup at a later date. Portion the cooled soup into airtight containers or freezer bags, leaving some space for expansion. It can be frozen for up to 3 months. When you’re ready to enjoy it, simply thaw it in the refrigerator overnight and reheat on low heat, adding a splash of broth if needed to restore its creamy consistency.
What should I do if my soup is too thick?
Not to worry! If your Roasted Tomato Basil Soup turns out too thick for your liking, simply stir in a little more vegetarian broth or water. Do this gradually until you reach your desired consistency. Remember to taste as you go; it’s easy to adjust flavors along the way while keeping that vibrant taste intact.
