Spring is here! What’s a more perfect way to celebrate than with a fresh tomato soup? Lately, most of my meal prep has been focused on preparing meals that are quick or very easy to make, so I thought that this would be a perfect time to share this meal with you. This recipe is one of my favorites that I’ve adapted from BBC Good Food and it is the embodiment of the perfect tomato soup. I grow tomatoes in my garden and so tomato soup is a must all year round, especially from now all the way to September.
Surprisingly, I always make this soup for the first time for the year in March, right in the prime of rainy season when all you want to do is cuddle up with a good book and some delicious soup. This soup, will not disappoint you if that is your wish. It is creamy, filled with flavor, and very satisfying. Ever since I was a child I haven’t been able to have tomato soup without a grilled cheese sandwich and I would highly that you do the same!
I’ve made this recipe many times regularly, but recently converted it into a slow cooker recipe, and let me tell you, the difference is extraordinary. A soup that was easily classed as delicious has been a hands down favorite! Slow cooking this recipe means richer notes of flavor on every count, and you can step away while everything is coming together beautifully. The only part that takes a bit of time (only 10 minutes) is cooking the main seasonings before hand which I recommend because it really helps their flavors to mellow with that of the tomato. I love to use an immersion blender at the end because it seems to be the perfect touch for smoothness of this soup.
I hope you try this out! Relax, have a sip, and enjoy the Spring!
