1 tbs fresh thyme

Melt butter in a large heavy pot over medium heat. Add onion and cook until completely soft and translucent, 8 minutes. Add garlic and thyme and sauté until fragrant, about 1 minute. Increase heat to medium-high, add tomato paste. Continue cooking, stirring often, until paste has begun to caramelize in spots, about 5 minutes.

Add tomatoes with juices, 1/2 teaspoon sugar, salt and pepper, and 4 cups water to pot. Increase heat to high and bring to a simmer. Reduce heat to medium. Simmer until flavors meld and soup reduces by 1/3rd. Remove soup from heat and using a stick blender, or in small batches in a conventional blender, puree until very smooth. Taste and season with any additional salt and pepper.

To serve, top soup with a slice of crunchy french bread and slice of cheese. In an oven safe bowl, broil under high heat until cheese is browned and bubbling.

The recipe sounds delicious, one problem though … It’s missing some steps it seems? ie how long to yo boil it for?

Hi Anon!

To reduce the soup by 1/3, it will take about 30 minutes!

Is it 2 tbs or cups of tomato paste?

Mmm, does that look yummy! I can’t wait to try this recipe out for myself! I always love the ones you ladies post here on the blog. I’m especially a fan of the grilled cheese, and the heirloom tomato and avocado salad you recently posted!

This sounds awesome – however, I would through in a bit of meat. ;)

This looks AMAZINGG!!! I’m totally making this tonight! One thing…do you take the skin off the fresh tomatoes at all? I’ve made home made tomato soup before and I think that’s how it went…but I could be wrong. Thanks! :)
