- 2 3/4 lb. tomatoes
- 8 cloves garlic
- 1 red onion
- 1 tbsp. olive oil
- 3 tbsps. finely grated Parmesan
- 2-inch piece of baguette
- Kosher salt and pepper to taste
- Prep by smashing the garlic, slicing the red onion into thick pieces, cutting the baguette into 1/2-inch-thick slices, and grating the Parmesan if needed.
- Heat oven to 325 degrees. On a baking sheet, toss the tomatoes, garlic, and onion with oil, salt, and pepper. Roast until the tomatoes and onion are tender, approximately 60 to 70 minutes.
- Transfer the vegetables and garlic into a pot with 4 cups of water. Bring to a boil over the stove, then puree using a blender or immersion blender until smooth.
- While the soup is on the stove, set the oven to broil. Place the baguette slices on a baking sheet and top with Parmesan. Broil until melted and serve with your soup.
