Who can resist these toasty, ooey-gooey, mini grilled cheeses? Not us!

We're taking homemade croutons up a notch and turning everyone's childhood favorite sandwich into bite-sized grilled cheese croutons. They're a flavorful, feel-good topper for soups, and they're really easy to make.

The best part about any homemade recipe is that you can use your favorite ingredients. For these grilled cheese croutons, we keep it classic with white sandwich bread and sharp cheddar cheese, but any cheese and bread will work (even if the bread's a bit stale).

Simply make grilled cheese as you normally would. Butter your bread, load it up with grated sharp cheddar cheese, and grill it until it's golden and crispy. Then slice off the crusts, and cut them into little cubes. Don't ditch the crusts though, they're perfect for dunking into soup!

A bowl of tomato soup with grilled cheese croutons is sure to lift spirits on the coldest and rainiest of days. If you have any leftover croutons, warm them up in the oven the next day and they'll be extra crispy and delicious!

Grilled cheese croutons ingredients

Here's what you need to make these crunchy grilled cheese croutons:

  • Butter – make sure your butter is at room temperature so you can spread it evenly over each slice of bread.
  • Bread – we use white sandwich bread, but you can use any kind of sliced bread like wholewheat, rye bread, or gluten-free if needed.
  • Sharp cheddar cheese – a sharp cheddar cheese gives these croutons a bold cheesy flavor. Feel free to mix it up with your favorite cheese like swiss cheese, havarti, gouda, or monterey jack.

How to make grilled cheese croutons

These gooey grilled cheese croutons are the perfect addition to tomato soup. It's just like making regular grilled cheese, but sliced into small squares. Here's how we make them in a few simple steps:

  1. Spread butter on one side of each slice of bread.
  2. Place two pieces of bread, buttered side down, on a heated frying pan. Top the slices with grated cheese and then sandwich them with the other two slices, buttered sides up.
  3. Cook until they're golden on the bottom, flip them, and cook a few minutes more until the cheese is visibly melty.
  4. Let them cool for a few minutes, slice off the crusts (but don't toss them!), and cut them into small squares. (Save the crusts for dipping in soup!

What's the best type of cheese to use?

We like classic sharp cheddar cheese, but any cheese that melts well will work. Try swiss cheese, havarti, gouda, or monterey jack.

How do I store leftover croutons?

If you have some leftovers, store them in the fridge in an airtight container for up to 3 days. To reheat, place them on a baking sheet and warm them in the oven until they're crisp.
