How To Make Garlic Butter Zucchini Grilled Cheese
Step 1: Prep Zucchini
Grate zucchini, then squeeze out as much moisture as possible using a towel or cheesecloth. This step is essential to prevent soggy patties.
Step 2: Make Mixture
In a bowl, combine grated zucchini, egg, Parmesan, cornstarch, salt, and pepper. Mix until it forms a thick batter that binds well together.
Step 3: Form Patties
Heat olive oil in a skillet over medium heat. Spoon the mixture into the pan and flatten into round or square “bread” patties.
Step 4: Cook Base
Fry each side for about 3–4 minutes until golden and crisp. Remove from the skillet and set aside on a plate.
Step 5: Assemble Sandwich
Place one zucchini patty back in the pan, sprinkle cheddar cheese on top, then add another patty on top to form a sandwich. This creates layers of flavor and texture.
Step 6: Melt Cheese
Cook the assembled sandwich a few minutes on each side until the cheese is fully melted and the outside is crispy. This ensures gooey cheese goodness in every bite.
Step 7: Serve
Let the sandwich cool slightly before slicing it into halves or quarters. Serve warm to enjoy the cheesy goodness!
Chef Tips for Perfect Results
