Roasted Tomato Basil Soup

03.13.2018

Is there a soup that says summer like a homemade tomato basil soup does? I’ve always loved tomato soup, anything but the canned kind though. This time around I roasted the tomatoes, onions and garlic to give the soup more depth of flavor and it really made the soup over-the-top delicious!

Tomato Basil Soup

This soup requires minimal ingredients but yields such amazing results! Here you combine several pounds of fresh tomatoes (which you roast to perfection), several cups of fresh basil and a fair amount of garlic.

And it doesn’t take much more then that – some broth, some onions, some time on the stove, a good pureeing and you’ve got an unbelievably delicious homemade tomato soup!

Also with that said when a recipe consists of mainly those ingredients you know it’s got to be good! This is the perfect use for the abundance of tomatoes you have in your garden in the summer or those you’ll find at the farmers market.

A Healthier Tomato Basil Soup

Looking to make it healthier? Well the soup itself is what I’d consider very healthy but if you want to keep it extra healthy you can just serve the soup sans grilled cheese croutons but if you want to go all out, definitely include them! They really just make the soup that much better.

I Love the Grilled Cheese Croutons!

Yes just picture it, a perfectly toasted, golden, crisp crusted, gooey, melty grilled cheese crouton soaking in a perfectly fresh roasted tomato basil soup.

It’s heavenly and you need to try it! Summer produce was made for things like so.

A Fresh Comforting Soup

This is how you do comfort food. A really healthy soup with smaller portions of grilled cheese included. It’s pretty much genius :).

I mean this soup will pretty much become one of your highlights of summer. All that fresh goodness in one bowl of bliss!

This soup requires minimal ingredients but yields such amazing results! When you combine several pounds of fresh tomatoes, several cups of fresh basil and a fair amount of garlic you know it's got to be good.

Ingredients

  • 2 1/4 lbs Roma tomatoes , halved lengthwise

  • 4 - 5 cups low-sodium vegetable broth
  • Grilled cheese croutons (optional), see notes

Instructions

  1. Preheat oven to 425 degrees. Place tomatoes on a rimmed baking sheet and toss with 3 Tbsp olive oil then season with salt and pepper (place Roma halves cut side upright).
  2. Place onion slices and garlic on a rimmed half sheet and toss brush with remaining 1 1/2 Tbsp olive oil on all sides, sprinkle with salt and pepper.

  3. Place baking sheet with tomatoes and half sheet with onions in oven side by side and roast onions 30 - 35 minutes until edges are golden, and tomatoes 40 - 45 minutes until golden. 

  4. Peel away any burnt papery layers of onions if there are any. Pull peels from tomatoes. 

  5. Pour onions and tomatoes into a large pot. Add 4 cups vegetable broth and the basil. Season with salt and pepper to taste. 
  6. Bring to a boil then reduce heat and simmer 20 minutes, adding an additional 1 cup vegetable broth to thin as desired. 
  7. Blend soup with an immersion blender or in small batches in a blender (only fill blender half full and remove center insert and cover with a kitchen towel). Serve warm topped with grilled cheese croutons if desired.

Recipe Notes

  • For the grilled cheese croutons use 6 slices of hearty sandwich bread, brush outsides of all slices with 1/2 Tbsp of butter on each. Sprinkle about 1/2 cup (2 oz) shredded mozzarella or cheddar over non-buttered sides of three slices. Top with remaining 3 slices of bread with buttered side up. Cook in a non-stick skillet over medium heat, reducing to medium-low as needed, until bottom is golden brown. Flip and cook opposite side until golden. Cool just slightly then cut into squares.
