What Is Gourmet Grilled Cheese?
Gourmet grilled cheese is an elevated version of the classic grilled cheese sandwich, using more complex flavors and high-quality ingredients. In the UK, we call this a cheese toastie.
Our recipe includes Gruyere, Gouda, homemade herb mayo, arugula, and caramelized onions, which add a depth of flavor that takes this dish far beyond your standard cheese version!
And let’s not forget the bread—using sourdough bread gives the sandwich the perfect balance of chewiness and crispiness when grilled, plus it toasts up beautifully to a golden brown in a hot skillet or griddle.
What’s great about this sandwich is its versatility. You can pair it with a bowl of Tomato Soup for a classic comfort food meal or serve it with a side salad.
You could even make a pot of French Onion Soup and have a gourmet meal! Making this soup would effectively kill two birds with one stone, as you’d be caramelizing onions for the soup and the best grilled cheese sandwich ever!
It’s the perfect addition to brunches, casual dinners, or your next Instagram-worthy comfort food post! (Don’t forget to tag us @_ThePurplePumpkinBlog)

Recipe Tips
- Butter the outside of the slices of bread generously for maximum toasty flavor and crunch.
- If you’re feeling adventurous, add ingredients like bacon, avocado, or a slice of ham to change things up.
- Want a different cheese combo? Try provolone, white cheddar, Swiss cheese, mozzarella, or havarti.
- Don’t like arugula? Switch it for baby spinach or your favorite salad greens.
- Use medium-low heat to ensure your cheese melts perfectly without burning the bread.
