- Freshly ground salt and pepper
For the Caramelized Onions
- ½ tablespoon olive oil
- 2 yellow onions, thinly sliced

- 1-2 cups water or vegetarian broth, depending on how thick you want the soup
- Freshly ground salt and pepper, to taste

How to Make Homemade Roasted Tomato Basil Soup
Step 1: Preheat the Oven
Preheat your oven to 400 degrees F. Line a large baking sheet with parchment paper. Place halved tomatoes and peeled garlic cloves on the baking sheet. Drizzle with 3 tablespoons of olive oil and season generously with salt and pepper. Roast in the oven for 40-45 minutes until they are tender and slightly caramelized.
Step 2: Caramelize Onions
While the tomatoes are roasting, prepare the caramelized onions. Heat ½ tablespoon olive oil in a large pot over medium heat. Add thinly sliced onions and stir to coat them with oil. Cook while stirring occasionally, checking every 5-10 minutes until they are golden brown and fully caramelized; this process usually takes about 20 minutes.
Step 3: Blend Ingredients
Once roasting is complete, let the tomatoes and garlic cool for 10 minutes. Transfer them to a food processor or high-powered blender, blending until smooth. Next, add fresh basil leaves and caramelized onions into the mixture; blend again until fully combined. Alternatively, you can use an immersion blender directly in the large pot if you prefer.
Step 4: Simmer the Soup
After blending, return the mixture back to the pot. Turn heat to medium-low and stir in dried oregano along with water or vegetarian broth. Season with salt and pepper as needed. You can also mix in any optional add-ins at this stage based on your preference. Allow your tomato soup to simmer for about 10 minutes before serving.
Now you’re ready to enjoy your delicious homemade roasted tomato basil soup! Serve it garnished with parmesan cheese alongside some crusty bread or grilled cheese if desired. Serves 4 people generously!

Common Mistakes to Avoid
Making homemade roasted tomato basil soup can be simple, but here are some mistakes to steer clear of for the best results.
- Using unripe tomatoes: Always choose ripe, flavorful tomatoes. They are sweeter and enhance the overall taste of your soup.
- Not roasting long enough: Roasting develops deep flavors. Ensure you roast your tomatoes and garlic for the full 40-45 minutes.
- Skipping the caramelized onions: Caramelizing onions adds a rich sweetness. Don’t rush this step; take your time to get them golden.
- Neglecting seasoning: Proper seasoning is key. Taste and adjust salt and pepper as needed throughout the cooking process.
- Overblending the soup: Blend just until smooth. Overblending can make it too thin; a bit of texture is nice in your soup.
