This Garlic Butter Zucchini Grilled Cheese is my favorite way to sneak greens into lunch without losing the comfort of gooey cheese and crispy bread. Swapping bread for golden zucchini patties gives you a veggie-packed twist that still delivers classic grilled cheese flavor and crunch.
I first whipped this up when I had too much zucchini in the fridge and no bread left I honestly never expected it to become such a go-to for quick dinners and cheesy cravings
Ingredients
- Zucchini: grated for tender texture and moisture be sure to use smaller firm zucchini for best flavor
- Large egg: binds the patties and boosts protein organic eggs work especially well here
- Freshly grated Parmesan: brings a rich salty depth stick to freshly grated for best melt and flavor
- Cornstarch: creates a crispier edge avoid potato starch which can make it gummy
- Salt and pepper: enhance all the flavors use flaky sea salt and freshly cracked pepper if possible
- Fresh churned garlic butter: infuses real garlic flavor unsalted butter gives you more control
- Shredded cheddar cheese: melts beautifully and adds that classic cheddar pull sharp cheddar gives more bite
Step-by-Step Instructions
- Prep the Zucchini:
- Place grated zucchini in a clean kitchen towel and squeeze out as much moisture as possible You want it almost dry for crisp edges
- Mix the Patty Base:
- Combine the dry zucchini with egg Parmesan cornstarch salt and pepper Use a fork and mix until everything sticks together but is not runny
- Shape and Cook the Patties:
- Melt garlic butter in a skillet over medium heat Scoop half the zucchini mixture onto one side of the pan and pat it into a square Repeat for the second half Keep them separated so they crisp up
- Brown and Flip:
- Cook about three to four minutes until the underside turns deep golden brown Carefully flip both patties Use a wide spatula and a gentle touch
- Add Cheese and Melt:
- Right after flipping sprinkle shredded cheddar over one patty and let warm until melting Place the second patty on top to form a sandwich Finish cooking until both sides are crisp
- Cool and Serve:
- Let the sandwich rest for a full minute before slicing This helps the cheese set and keeps everything together

The garlic butter is my personal favorite part of this sandwich My kids love the crispy edges and I love that zucchini sneaks its way into every bite This turned into a family win on a busy weeknight
Storage Tips
Store leftovers tightly wrapped in the fridge They are best eaten fresh but you can reheat them on a skillet to bring back the crispiness Avoid microwaving as it softens the zucchini patties
