Preparing Homemade Roasted Tomato Basil Soup
This comforting bowl of homemade roasted tomato basil soup is perfect for any season, but especially during chilly months. The process may seem extensive, but trust me, each step is straightforward and quite rewarding. Let’s walk through the preparation together!
Roasting the tomatoes and garlic
Start by preheating your oven to 400 degrees F. While it’s warming up, line a large baking sheet with parchment paper for easy cleanup. Take 3 pounds of roma or plum tomatoes, cut them in half, and place them cut side up on the baking sheet. Add in 8 cloves of peeled garlic for that aromatic flavor explosion. Drizzle everything with 3 tablespoons of olive oil, then sprinkle generously with salt and pepper.
Roast the tomatoes and garlic in the oven for 40-45 minutes, or until they’re soft and slightly caramelized. If you’ve never roasted tomatoes before, expect a rich, sweet flavor to develop. It’s magical!
Caramelizing the onions
While the tomatoes are roasting, let’s caramelize 2 thinly sliced yellow onions. In a large pot, add ½ tablespoon of olive oil over medium heat. Stir the onions to coat them in the oil, then relax! Let them cook, stirring occasionally. It should take about 20 minutes for them to turn beautifully golden-brown. This step adds a depth of flavor that perfectly complements your roasted tomatoes.
Did you know that caramelizing onions actually enhances their natural sugars? So, while it takes some time, it’s well worth the effort!
Blending the ingredients
Once your tomatoes and garlic are roasted to perfection, take a moment to let them cool for about 10 minutes. Then, add them into a food processor or a high-powered blender and blend until smooth. Next, incorporate the caramelized onions and ½ cup of fresh basil leaves. Don't forget to blend again until everything is harmoniously mixed. If you prefer, an immersion blender can also work wonders right in the pot!
Simmering the soup
Transfer your blended mixture back into the large pot over medium-low heat. Now, add in ½ teaspoon of dried oregano, 1-2 cups of water or vegetarian broth, and season with salt and pepper to taste. If you want it creamier, consider adding a splash of coconut milk or heavy cream. Allow the mixture to simmer for about 10 minutes, which lets all those gorgeous flavors meld together.
Garnishing and serving
When ready to serve, ladle the soup into bowls and top with grated Parmesan cheese for an extra flavor boost. For a delightful pairing, serve with a classic grilled cheese sandwich.
With these simple steps, your homemade roasted tomato basil soup will impress family and friends alike. Plus, it’s perfect for meal prep—store leftovers in an airtight container in the fridge for up to 5 days or freeze for later. Enjoy every warm, comforting spoonful!

Variations on Homemade Roasted Tomato Basil Soup
Creamy Vegan Tomato Basil Soup

You can customize the flavor by stirring in a dash of nutritional yeast for a cheesy taste without the dairy.
Spicy Roasted Tomato Variation
If you crave a little heat, try turning up the flavor dial with a spicy roasted tomato variation. Just toss a few chopped jalapeños or red pepper flakes with your tomatoes before roasting. The smoky, spicy undertones will take your homemade roasted tomato basil soup on an exciting twist, making it a delightful choice for those warm evenings when you’re entertaining friends.
