Escape into a bowl of pure comfort with this copycat Panera's Tomato Soup, a vibrant and deeply flavorful dish perfect for any season. Imagine serving it alongside a gooey grilled cheese sandwich, a crisp green salad, or perhaps a side of Instant Pot Mac and Cheese for a full meal.
Add the butter and onion to an enameled dutch oven pot. Saute on medium high for 5 to 6 minutes until onions are soft and translucent. Add the tomato paste and balsamic vinegar. Cook for one more minute.
Remove the roasted tomatoes from the oven. Add the tomatoes, garlic, 3 of the thyme sprigs, and the fresh basil leaves to the dutch oven pot. Add the vegetable broth. Simmer for 30 minutes.
3 cups vegetable broth, 10 fresh Basil leaves
Using the stick blender, puree the soup mixture in the dutch oven pot until the tomato soup is creamy. Simmer until ready to serve.
Notes
Tomatoes: If you don't have seasonal ripe tomatoes, use the Caprese tomatoes that are about 2" diameter in the plastic tub. One tub should be about 2 lbs.
Peeling the tomatoes before or after roasting is not necessary.
Don't Rush the Roasting: Allow your tomatoes ample time in the oven to truly caramelize and soften; this is where the deep, concentrated flavor of the soup develops.
Use Fresh, Ripe Basil: The quality of your basil significantly impacts the final taste, so opt for fresh, vibrant leaves for the best aromatic and bright notes.
Adjust Seasoning at the End: Taste the soup after blending and before serving, adding salt, pepper, or a touch more sugar if needed, to perfectly balance the flavors.
