Our easy Roasted Tomato Soup recipe is rich, cozy, and tastes just like the one from Panera Bread, only better because you made it yourself. Roasting the tomatoes brings out a natural sweetness that makes this soup taste like it simmered all day, even though it's simple enough for a weeknight.
The Best Roasted Tomato Soup
I love how fresh and healthy this roasted tomato soup recipe is (especially since we're usually serving it with some hearty grilled cheese dunkers on the side!). I like to double it for meal prep lunches or to freeze the leftovers for a seconds dinner another time.
My biggest tip is to use high quality tomatoes for best flavor! Find a fruit stand, a neighbor with an overflowing garden, or go to a high quality market (Sprouts and Trader Joes usually have good tomatoes!).

How to make Roasted Tomato Soup:
Roast the Tomatoes: Toss halved plum tomatoes with olive oil, salt, and pepper, then spread them on a baking sheet and roast until they're soft and slightly caramelized. This step is what gives the soup so much flavor, so don't skip it!
Build the Base: Sauté onions and garlic with butter and a pinch of red pepper flakes until soft, then add canned tomatoes, fresh basil, thyme, and broth along with the roasted tomatoes and all their juices. Simmer everything together so the flavors have time to blend.
Blend and Serve: Purée the soup until smooth using a blender or immersion blender, then ladle it into bowls and top with grated Parmesan. Serve with a side of cheesy bread for dunking.

My husband and I made the soup. We tested it as written, and it tasted perfect. We plan to have it for lunch tomorrow, as the instructions said it was better after a day. I will serve it with 1/2 a grilled cheese sandwich.
