Recipe Equipment

You only need a handful of basic kitchen tools to make this zucchini grilled cheese:

Large mixing bowl
Box grater
Clean kitchen towel or cheesecloth
Baking sheet
Parchment paper
Spatula
Nonstick skillet or cast-iron skillet
Small bowl
Measuring cups and spoons
Wire cooling rack, optional

Helpful tip: Removing as much moisture as possible from the grated zucchini is one of the most important steps. A clean kitchen towel works wonderfully for squeezing out excess liquid.

Ingredients

For the Zucchini “Bread”

2 medium zucchini, approximately 12 ounces total
1 large egg
½ cup shredded mozzarella cheese
¼ cup finely grated Parmesan cheese
2 tablespoons almond flour
½ teaspoon garlic powder
½ teaspoon Italian seasoning
¼ teaspoon salt
¼ teaspoon black pepper

For the Garlic Butter

2 tablespoons unsalted butter
1 clove garlic, finely minced
1 tablespoon chopped fresh parsley
¼ teaspoon Italian seasoning

For the Grilled Cheese

4 slices cheddar cheese, or approximately 3–4 ounces shredded cheese
1 tablespoon butter, for skillet cooking if needed

Why These Ingredients Work

Zucchini provides moisture, flavor, and structure while replacing traditional bread.

Mozzarella and Parmesan help bind the zucchini mixture while adding savory flavor and cheesy richness.

Almond flour absorbs some moisture and helps create a firmer, more bread-like texture.

The garlic butter adds an irresistible savory aroma and helps the outside become beautifully golden and crisp.

For the filling, cheddar is an excellent choice because it melts well and provides a stronger flavor, but you can easily experiment with other cheeses.

Ingredient Notes

Choose Firm Zucchini

Look for medium zucchini that feel firm and have smooth, unblemished skin. Very large zucchini often contain more seeds and moisture, which can make the zucchini bread harder to crisp.

Remove Excess Water

This is the most important ingredient-preparation tip.

Zucchini contains a lot of water. After grating, place it in a clean towel and squeeze firmly until very little liquid comes out.

The drier your zucchini is, the easier it will be to create sturdy, crispy “bread.”

Cheese Choices

Cheddar gives you a classic grilled cheese flavor, while mozzarella creates an extra stretchy center.

You can also try Monterey Jack, Colby Jack, provolone, or a combination of cheeses.

Garlic

Fresh minced garlic gives the garlic butter a stronger flavor than garlic powder. Keep the pieces small so they cook evenly without burning.

How to Make Keto Garlic Butter Zucchini Grilled Cheese

Step 1: Prepare the Zucchini

Preheat your oven to 400°F (200°C).

Grate the zucchini using the large holes of a box grater.

Place the grated zucchini into a clean kitchen towel or cheesecloth. Gather the towel around the zucchini and squeeze firmly over the sink.

Keep squeezing until you remove as much liquid as possible.

Don’t skip this step. Excess moisture is the biggest enemy of crispy zucchini bread.

Step 2: Make the Zucchini Mixture

Place the squeezed zucchini into a large bowl.

Add the egg, shredded mozzarella, Parmesan, almond flour, garlic powder, Italian seasoning, salt, and black pepper.

Stir everything together until the mixture is evenly combined.

It should be moist but hold together when pressed.

Step 3: Shape the Zucchini Bread

Line a baking sheet with parchment paper.

Divide the zucchini mixture into four portions.

Shape each portion into a flat rectangle roughly the size of a traditional sandwich bread slice.

Keep the pieces relatively even in thickness so they cook at the same rate.

Press the mixture firmly together with your fingers or the back of a spoon.

Step 4: Bake Until Golden

Place the baking sheet in the preheated oven.

Bake for approximately 15–20 minutes, carefully watching toward the end.

The zucchini slices should become firm and lightly golden around the edges.

For an even crispier finish, carefully flip them halfway through baking and continue cooking until both sides are golden.

Once finished, let them cool for several minutes so they firm up further.

How to Make Garlic Butter

Step 5: Prepare the Garlic Butter

While the zucchini bread is baking, melt 2 tablespoons of butter in a small skillet or saucepan over low heat.

Add the minced garlic and Italian seasoning.

Cook gently for approximately 30–60 seconds, just until the garlic becomes fragrant.

Remove from the heat and stir in the chopped fresh parsley.

Be careful not to brown or burn the garlic because burnt garlic can taste bitter.

Assemble the Grilled Cheese

Step 6: Add the Cheese

Place two zucchini bread slices on a work surface.

Layer each with cheddar cheese.

Top with the remaining zucchini slices to create two sandwiches.

Press them gently together without crushing the bread.

Step 7: Brush With Garlic Butter

Generously brush the outside of each sandwich with the prepared garlic butter.

Make sure you cover the surface evenly.

This gives the grilled cheese a rich buttery flavor while helping the outside become beautifully golden in the skillet.

Step 8: Cook Until Crispy and Gooey

Heat a nonstick or cast-iron skillet over medium-low heat.

Place the sandwiches into the skillet.

Cook for approximately 3–4 minutes per side, gently pressing with a spatula as they cook.

You’re looking for a crispy, golden-brown exterior and completely melted cheese inside.

Keep the heat moderate. If the skillet becomes too hot, the outside can burn before the cheese has time to melt.

When the cheese is gooey and the outside is golden and crisp, transfer the sandwiches to a plate.

Let them rest for 1–2 minutes, then slice and serve.

Serving Suggestions

This Keto Garlic Butter Zucchini Grilled Cheese is delicious on its own, but pairing it with the right side can turn it into a complete meal.

Serve With Soup

For a classic comfort-food combination, serve your sandwich with:

Low-carb tomato soup
Creamy cauliflower soup
Chicken vegetable soup
Broccoli cheddar soup

Add a Fresh Salad

A simple green salad with lettuce, cucumber, avocado, and a light dressing creates a fresh contrast to the rich, cheesy sandwich.

Add Keto-Friendly Dips

Try dipping your grilled cheese into:

Sugar-free marinara sauce
Homemade ranch dressing
Garlic aioli
Creamy avocado dip

The crispy zucchini exterior and creamy cheese center make this sandwich perfect for dipping.

Pro Tips & Variations

For the crispiest zucchini bread, squeeze out as much moisture as possible before mixing the ingredients. You can also let the baked zucchini slices cool for a few minutes before assembling the sandwich so they become firmer.

For extra garlic flavor, add a small pinch of garlic powder to the butter. Want some heat? Add crushed red pepper flakes or a thin layer of sliced jalapeño.

Try different cheeses for completely different flavors. Pepper Jack adds heat, provolone gives a milder taste, and smoked cheddar creates a richer flavor.

For a protein boost, add a thin layer of cooked bacon, sliced turkey, or shredded chicken.

Storage Information

Refrigerator

For best results, store the zucchini bread separately from the cheese filling when possible.

Place cooled zucchini slices in an airtight container and refrigerate for up to 3 days.

Freezer

The baked zucchini bread can be frozen for approximately 1–2 months.

Place parchment paper between pieces to prevent sticking.

Reheating

For the crispiest texture, reheat assembled sandwiches in a skillet or air fryer rather than the microwave.

Cook until heated through and the cheese becomes warm and gooey again.

Frequently Asked Questions

Is zucchini grilled cheese keto-friendly?

This version is designed to be lower in carbohydrates than a traditional grilled cheese because zucchini replaces wheat bread. However, exact carbohydrate counts depend on your ingredients and portion size.

How do I keep zucchini bread from getting soggy?

The key is removing excess water from the grated zucchini. Squeeze it very thoroughly before mixing the batter, and bake the zucchini slices until they’re firm and golden.

Can I use frozen zucchini?

Fresh zucchini is recommended because frozen zucchini generally contains more moisture after thawing. If using frozen zucchini, thaw it completely and squeeze out as much water as possible.

What cheese melts best for grilled cheese?

Cheddar, mozzarella, Monterey Jack, Colby Jack, and provolone are all excellent choices. For maximum meltiness, combine a flavorful cheese such as cheddar with mozzarella.

Can I make this in an air fryer?

Yes. The zucchini bread can be cooked in an air fryer, although cooking times vary between models. Check it frequently so it becomes golden without burning.

Can I add meat?

Absolutely. Cooked bacon, turkey, chicken, or ham can turn this into a more substantial keto lunch.

Why is my zucchini bread falling apart?

Usually, this happens because the zucchini contains too much moisture or the slices haven’t cooked long enough. Make sure the zucchini is squeezed thoroughly and baked until firm.
