Roasted Tomato Basil Soup Recipe

I know that I can’t be the only one that still has tomato coming out her ears. Right? I was wracking my brain about what to do with our huge colander stacked high with tomatoes, when I suddenly thought, what if I use those flavors, but make a soup to help move us into fall?

DING DING DING! Creamy tomato basil soup with mini grilled cheese croutons was born.

I love those little grilled cheese bites that act like little croutons in the soup. I’m not even kidding, it’s so delicious together.

The best soup is always made when you roast the veggies first. Roasting tomatoes always sounds a little fancy when in fact it’s the easiest thing you can do in the kitchen. Slice, drizzle with olive oil, salt and pepper and roast in the oven.

How Long Does Tomato Soup Last?

Creamy tomato basil soup will keep 2-3 days in the refrigerator.

Can You Freeze Tomato Soup?

Good news: tomato soups freeze very well! However, we recommend leaving the cream out if planning on freezing this soup. Stir the cream in when you’re reheating the frozen soup!

What Are the Best Tomatoes for Tomato Soup?

We recommend using Roma tomatoes or vine ripened tomatoes for this creamy tomato basil soup. Avoid using beefsteak tomatoes, as we find they lack the bold flavor this soup needs.

Tips for Making Fresh Tomato Soup

  • If you’d like to make this tomato soup healthier, you can use a blend of heavy cream and unsweetened almond milk. Or, use all unsweetened almond milk!
  • For an extra punch of flavor, try adding a few shakes of dried Italian herbs and / or red pepper flakes to this soup as it’s simmering.
  • You can use really any kind of bread you’d like to make the grilled cheese croutons. We just like using a baguette since it crisps up nicely.
