This version turns classic comfort food into a craveable low carb lunch or dinner that feels both familiar and deliciously new with every garlicky bite.
My first attempt at this recipe was a total hit with my sister who never eats zucchini and now she requests it whenever we visit each other You will love how savory and satisfying it is even without bread
Ingredients
- Grated zucchini: gives structure and moisture for those crisp edges use fresh firm zucchini for best results and squeeze well to avoid soggy patties
- Egg: acts as a binder to help the patties set look for large eggs with golden yolks for richer flavor
- Freshly grated Parmesan: brings salty depth and helps everything brown buy a wedge and grate it yourself for the fullest taste
- Cornstarch: ensures the patties hold together and get crispy always check for smooth texture without lumps
- Salt and pepper to taste: pull everything together use flaky salt and fresh cracked black pepper for the most flavor
- Fresh churned garlic butter: infuses the whole sandwich with rich savory aroma use real butter with minced garlic or a quality garlic butter spread
- Shredded cheddar cheese: melts perfectly and brings that classic grilled cheese stretch use sharp cheddar for bolder flavor and always shred it fresh when possible
Step-by-Step Instructions
- Prep the Zucchini:
- Squeeze as much moisture as possible from grated zucchini using a cheesecloth or sturdy kitchen towel This step keeps the patties crisp and prevents them from falling apart
- Make the Zucchini Dough:
- Combine the dry zucchini with the egg Parmesan cornstarch salt and pepper in a mixing bowl Mix with a fork until it becomes a dough like mixture that easily holds together but is not wet
- Form and Cook Patties:
- Heat garlic butter in a nonstick skillet over medium heat Scoop half the zucchini dough onto one side of the skillet and shape it into a round patty Repeat with the remaining mixture Cook three to four minutes per side until golden and crispy
- Add Cheese and Assemble:
- Layer shredded cheddar generously on one patty then place the other patty on top Press gently to form a sandwich Let cook for another three minutes so the cheese melts completely
- Cool and Serve:
- Transfer the sandwich to a cutting board Let it rest for about a minute before slicing This helps it set and keeps the cheese from spilling out

The Parmesan in this sandwich is hands down my favorite taste booster It reminds me of summer visits at my grandmas where every meal started with something cheesy This sandwich brings me right back
