Ingredients
– 2 slices of sourdough bread
– Mayonnaise (enough to spread thinly on the outside of both bread slices)
– Dijon mustard (enough to spread on the inside of one bread slice)
– 28 to 56 grams (1 to 2 ounces) grated sharp cheddar cheese
– 28 to 56 grams (1 to 2 ounces) grated Gruyère or raclette cheese
– Butter (enough to coat the skillet for cooking)
– Gluten-free sourdough slices
– 28 to 56 grams grated sharp cheddar and Gruyère
– Vegan cheese shreds
– Mayonnaise and Dijon mustard
– Plant-based mayo and mustard
Instructions
1-Gather all ingredients and equipment, including your nonstick or cast-iron skillet, and heat it over medium-low heat.
2-Spread a thin layer of mayonnaise on the outer sides of both bread slices for that golden crust.
3-Flip one bread slice and spread Dijon mustard on the inside for a tangy flavor boost.
4-Layer the grated sharp cheddar and Gruyère or raclette cheese on the mustarded side, using 28 to 56 grams of each for the right amount of gooeyness.
5-Place the other bread slice on top, with the mayo side facing out, to form the sandwich.
6-Melt enough butter in the skillet to coat the bottom, then add the sandwich and cover with a lid. Cook for 2 to 3 minutes until the bottom is golden and crispy.
7-Carefully flip the sandwich, cover again, and cook for another 1 to 3 minutes until the other side is golden and the cheese is fully melted.
8-Adjust the heat as needed to avoid burning, then remove from the pan, let it cool slightly, and slice into triangles for serving.
Notes
🔥 Use medium-low heat and cover the pan to trap steam – this ensures the cheese melts perfectly without burning the bread
🧀 Grate your cheese instead of using slices for faster, more even melting throughout the sandwich
