Roasted Tomato Soup with Grilled Cheese Croutons is creamy tomato soup topped with grilled cheese cubes, then topped with shredded Gruyere and cheddar cheese. The bowls are placed under the broiler to melt and brown the cheese, giving the dish a deliciously crispy and golden top. Very much like how French Onion Soup is served! It combines the classic flavors of grilled cheese and tomato soup, making it a comforting and flavorful meal! It all starts with my Roasted Tomato Soup, which is delicious on its own, too!

Ingredients & Substitutions

Tomatoes: Fresh tomatoes are the star of this soup, so be sure to pick out the best ones. When selecting a tomato, go for a flawless, bright red one that feels heavy and dense when picked up. Give it a gentle squeeze – it should have some give, but not be too soft. Smell it close to the stem; you want an earthy aroma for the best flavor. If it lacks scent, it won’t contribute much to the recipe.

Grilled Cheese: The grilled cheese is a simple recipe with a slice of sharp cheddar. I also have an Air Fryer Grilled Cheese recipe you could use. Or, if you are craving even more cheese, check out my Crispy Grilled Cheese Sandwich.

Cheese: In addition to the slice of cheese in the sandwich, I topped the cubes of the sandwich in the soup with shredded Gruyere and sharp cheddar cheese. Then, I broiled the soup for a couple of minutes until the cheese was hot and bubbly.

What Are The Best Bowls For Serving Roasted Tomato Soup?

Since this recipe is broiling the cheese directly in the serving dish, use oven-safe bowls or ramekins. If you are not planning to broil the cheese, you can use any sort of decorative soup bowl or even a mug for a neat presentation.

Steps for Making and Assembling Roasted Tomato Soup with Grilled Cheese Croutons.

Can I Make Roasted Tomato Soup Ahead Of Time?

Yes, you can make the roasted tomato soup in advance to save time when ready to assemble the bowls. Once you have the tomato soup made, let it cool completely. Then, store the soup in an airtight container in the refrigerator for up to 3-4 days. When ready to put together the bowls, heat the soup on the stovetop while you make the grilled cheese sandwiches.

Can I Roast Vegetables in an Air Fryer?

Yes, you can roast the tomatoes, onion, and garlic in an air fryer instead of the oven. I would opt for no bigger than a Roma tomato when using the air fryer in this recipe. To get started, preheat the air fryer to 400°F and line the basket with parchment paper. Then, it’s time to roast the veggies.

  1. Wash the tomatoes by gently rubbing them under running water. Cut each tomato in half and lay them cut side up in the lined basket. (Don’t worry about removing the stem or peeling the tomatoes for now; it is easy to do after roasting them.)
  2. Add the onion wedges and peeled garlic cloves into the basket.
  3. Drizzle the vegetables with olive oil. Then, sprinkle with salt, pepper, and sugar.
  4. Roast in the air fryer for 30 minutes, or until the vegetables have completely softened.

Depending on the size of your air fryer, you may have to work in batches.

How To Store Roasted Tomato Soup with Grilled Cheese Croutons

Although best served fresh, you can store leftovers if needed. To store grilled cheese roasted tomato soup, I recommend storing the grilled cheese cubes separately from the soup. Otherwise, the texture will get soggy. The soup can be stored in an airtight container in the refrigerator for up to 3-4 days. Store cubes of grilled cheese in a separate container in the refrigerator for up to 2-3 days. Reheat the soup on the stovetop while reheating the grilled cheese cubes in the oven or in an air fryer to crisp them up again.

  1. Amanda…do you think this could be canned (steam canner) and then do the grilled cheese croutons when the soup is actually reheated?

  2. I assume we can’t freeze this due to the heavy cream. Can I portion out the soup for serving two and add cream to that and freeze the rest?

    1. The directions are in the recipe card. For an air fryer you can make the sandwich, heat in air fryer, then cut into cubes and put back into airfryer.
