Instructions
Step 1: Prepare the Zucchini
Wash the zucchini thoroughly and grate it using the large holes of a box grater. Place the shredded zucchini into a bowl and sprinkle with salt. Allow it to sit for about 10 minutes.
Transfer the zucchini to a clean kitchen towel and squeeze out as much moisture as possible. Removing excess water is essential for achieving a crispy crust.
Step 2: Make the Zucchini Mixture
In a mixing bowl combine:
- Squeezed zucchini
- Egg
- Parmesan cheese
- Garlic powder
- Onion powder
- Italian seasoning
- Black pepper
- Flour
Mix until everything is evenly combined.
The mixture should hold together without being too wet.
Step 3: Prepare the Bread
Spread softened butter evenly on one side of each bread slice.
On the opposite side of each slice, spread a thin layer of the zucchini mixture, gently pressing it onto the bread.
The zucchini layer should be about ¼ inch thick.
Step 4: Heat the Pan
Heat a large non-stick skillet over medium heat.
Add olive oil and allow it to warm for about one minute.
Avoid high heat, as it may burn the zucchini before the cheese melts.
Step 5: Cook the First Side
Place two bread slices zucchini-side down into the skillet.
Cook for 4–5 minutes until the zucchini develops a crispy golden crust.
Do not move the bread while cooking.
Step 6: Add the Cheese
Flip each slice carefully.
Immediately place cheddar and mozzarella cheese on top.
If using optional ingredients like tomato or basil, add them now.
Top with the remaining bread slices, buttered side facing outward.
Step 7: Grill the Sandwich
Cook for another 3–4 minutes.
Flip carefully once more.
Cook an additional 3–4 minutes until:
- Bread is golden brown
- Cheese is fully melted
- Sandwich is heated through
Reduce heat if necessary to prevent burning.
Step 8: Rest Before Serving
Transfer the sandwiches to a cutting board.
Allow them to rest for 2 minutes before slicing.
This helps keep the melted cheese inside.
Slice diagonally and serve immediately.
Cooking Tips
- Always squeeze as much liquid as possible from the zucchini.
- Use freshly shredded cheese for better melting.
- Medium heat produces the crispiest crust.
- Thick bread works best because it holds the filling well.
- Avoid overcrowding the skillet.
- Cover the pan for one minute if the cheese needs extra time to melt.
- A cast-iron skillet creates an even crispier sandwich.

Storage Instructions
Refrigerator
Store leftovers in an airtight container for up to 2 days.
Freezer
Not recommended, as the zucchini loses its crisp texture after thawing.
Reheating
Warm in a skillet over medium-low heat for 4–5 minutes per side.
Avoid microwaving, as it softens the crispy crust.
Common Mistakes to Avoid
- Not removing enough moisture from the zucchini
- Cooking over high heat
- Using too much zucchini mixture
- Overfilling with cheese
- Flipping too early
- Using pre-shredded cheese only
