Roasted Fennel and Tomato Soup

March 11, 2019

Roasted fennel and tomato soup is a transitional soup. It gets you through the end of winter and the rainy start to spring. Tomatoes, fennel, onion, and garlic get roasted in the oven until caramelized. Pureé the soup until smooth and enjoy a slightly spicy and sweet new take on tomato soup.

This time of year is perfect for cozying up with a bowl of tomato soup. Throw in some funky croutons or a grilled cheese and you got me hooked! It’s not quite spring and winter hasn’t let go of its chilly grip on our souls.

I know that is a bit ominous sounding. I feel bad for my winter coat in all this. She gets the brunt of all my loathing stares. 

I am ready to move on to the next season and a new, lighter coat.

The only good thing about this limbo weather is soup season is still appropriate. My favorite tomato soup of all time comes from Panera. Anybody else ever get a craving for that creamy tomato soup with all the croutons on top?

I decided to give my go-to roasted tomato soup a seasonal adjustment and add in fennel. 

Fennel adds a slightly sweet yet spicy twist to tomato soup. Roasted fennel and tomato soup will carry you from cold winter days through those chilly and rainy spring storms. It’s going to be your new favorite.

All the usual suspects: tomatoes, onions, and garlic are tossed with chopped fennel and some olive oil. They get roasted in the oven for 20 minutes until nicely caramelized.

I like to add the roasted ingredients right to a pot along with a can of fire-roasted tomatoes and stock and use my immersion blender to pureé until smooth. If you don’t have an immersion blender, toss it all in a blender and puree until smooth. Either way, it gets the job done.

Let’s all channel our winter loathing into creating bowls of soup instead, eh? I feel like it is a much better way to channel our energy. Plus I don’t know how many more aggressive tosses across the room my winter coat can take.
