- Tomato Soup With Grilled Cheese Croutons
Why we love this recipe ❤️
Is there anything more warm and wonderful than a steaming hot bowl of homemade tomato soup and a crispy gooey grilled cheese sandwich?
That combo belongs in the Lunchtime Hall Of Fame, and the only possible improvement I can think of is to have the grilled cheese sandwich actually floating in the soup.
And you don’t have to pick – you can have a spoonful that has BOTH. Both is good. Both is delicious!
I’m also here to tell you that tempting as it might be to run for that can of Campbells, homemade tomato soup is SO much better and not that hard. And crispy gooey grilled cheese croutons deserve really great soup.
What are croutons? 🍞
A crouton is a small cube of toasted bread. Sometimes they are flavored with dried herbs or garlic or cheese, and they are a scrumptious crunchy topping for salads or soups. Fun fact: the French word for crust is “croute,” which is super close to crouton…ooh-la-la!

Ingredient notes and substitutions 📝
- Tomatoes: Whole peeled tomatoes are sometimes in the canned veggie aisle and sometimes with the pasta sauces.
- Broth: If you want this recipe to be fully vegetarian you can use vegetable broth instead of chicken broth.
- Cheese: We like American cheese for a classic grilled cheese, but you can swap in your favorite cheese.

How to make this recipe 👩🏻🍳

STEP 1: Puree tomatoes with their juices in a food processor.

STEP 2: Heat 2 tablespoons olive oil in a medium pot over medium high heat. Add garlic and onion and cook, stirring, about 6 minutes or until onions are tender.
Add tomatoes and chicken broth and bring to a boil, then reduce heat to a simmer and cook for 30 minutes, stirring occasionally.

STEP 3: Puree in blender (or with immersion blender) until smooth and season to taste with salt and pepper. Return to pot and keep warm while you make the sandwiches.

STEP 4: Heat a skillet or griddle over medium high heat.
Butter four slices of bread. Put cheese in between slices and cook in skillet butter side down until deep golden brown on each side.

STEP 5: Cool slightly, then cut into crouton-sized cubes.

STEP 6: Ladle soup into bowls and float croutons on top. Serve at once.
Recipe FAQs 🧐
You can! But I promise it is worth the time to make this super easy homemade version.
An immersion blender (which is also called a hand blender or a stick blender) is a portable handheld little blender that can purée foods right in the pot, saving you the time and mess of getting out your regular counter blender. Pro Tip: Make sure you keep the blender end under the surface of the soup so it doesn’t splash around.
The soup part can absolutely be made ahead and reheated over medium heat on the stovetop. Make the grilled cheese croutons right before you are ready to serve it up.
