Since I was a young girl, tomato soup with a grilled cheese sandwich was my favorite lunch. To this day, I can’t turn it down. And when is the best time for homemade tomato soup? When you have fresh garden tomatoes from the farmer’s market or your own backyard! That’s why I’m bringing you a soup recipe at the end of summer–you can turn your summer tomatoes into the perfect soup.

You’re going to love this healthy Roasted Tomato Soup; roasting the tomatoes brings out their natural sweetness and tremendous depth of flavor. This is an easy recipe that can be a part of your easy weeknight dinners rotation, perfect for back to school time.

Recipe Ingredients–What You Need

Fresh ingredients work together to make one of my favorite soups ever. Here’s what you’ll need!

3 lbs Fresh Tomatoes

Many different kind of tomatoes can be used for this recipe.Plum tomatoes and Roma tomatoes often offer the best flavor, but cherry tomatoes, grape tomatoes, globe tomatoes, and heirloom tomatoes can all be used here. Look for ripe tomatoes.

1 Yellow Onion

Yellow onions have a sweet flavor when roasted that compliments the tomatoes here.

3 Cloves of Garlic

Roasted garlic adds more depth of flavor to to our soup.

2 tablespoons of Olive Oil

Olive oil is used when roasting the vegetables and gives flavor and richness.

3 tablespoons Tomato Paste

Tomato paste deepens the tomato flavor. This is extra helpful if you’re using regular, grocery store tomatoes as they can lack flavor; tomato paste will help achieve a rich flavor.

1-2 cups Vegetable Broth

For a thicker soup, use 1 cup broth, for a thinner soup, use 2 cups. Chicken broth or chicken stock can also be used here.

Salt and Pepper

We will season the vegetables before roasting.

1/3 cup Fresh Basil Leaves

Tomato + basil = the best tomato soup so I had to include basil in this recipe.

1/3 cup Freshly Grated Parmesan Cheese

Parmesan cheese compliments the flavor profile of this soup perfectly.

Step-By-Step Instructions for this Easy Roasted Tomato Soup Recipe

Preheat the oven to 400 degrees.
Core and seed the tomatoes and cut them into wedges. Peel and cut the onion into wedges. Peel the garlic cloves.
Place the tomatoes, onion, and garlic in a single layer on a baking sheet, drizzle with 2 tablespoons olive oil, and about 1 tablespoon salt and 1/2 teaspoon freshly ground black pepper.
Roast in the preheated oven for 30 minutes.
Transfer the roasted tomatoes, onions, and garlic to a blender and blend until smooth. A food processor may be used here if you don’t have a large blender or you can do this in batches.
In a soup pot, combine the blended tomatoes, 1 cup vegetable broth, tomato paste, finely chopped fresh basil leaves, and parmesan cheese. Add another cup of broth if you’d like your soup thinner.
Heat over medium heat a few minutes, until hot, and serve.

To make this a full meal, I suggest adding a sandwich and salad. It would be perfect with The Ultimate Grilled Cheese Sandwich and this Mediterranean Quinoa Salad with Chicken.
