Ingredients You’ll Need

For the Zucchini “Bread”:

• 1 large zucchini (about 8-10 inches long)
• 1 cup shredded sharp cheddar cheese, divided
• 1/4 teaspoon garlic powder
• 1/4 teaspoon smoked paprika (optional, but recommended)

For the Sandwich Filling:

• 1 tablespoon avocado mayonnaise
• 1 teaspoon Dijon mustard
• 3 ounces sliced organic chicken breast (or turkey)
• 2 large butter lettuce leaves
• 2-3 thick tomato slices
• 3-4 thin slices red onion
• 1/3 ripe avocado, sliced
• Everything bagel seasoning for sprinkling

Step-by-Step Instructions

Preparing the Zucchini Base

1. Preheat and prep: Set your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
2. Slice the zucchini: Using a mandoline slicer, vegetable peeler, or sharp knife, cut the zucchini lengthwise into thin, even slices (about 1/8-inch thick). You’ll need enough slices to create two overlapping layers.
3. Remove moisture: Lay the zucchini slices on paper towels and gently pat dry. This crucial step prevents sogginess and ensures crispiness.
4. Create the base layer: Sprinkle half of the shredded cheese on the parchment paper in a rectangular shape, roughly 6×8 inches.
5. Layer the zucchini: Arrange the zucchini slices over the cheese, overlapping them slightly to create a solid, even layer. Season with garlic powder and smoked paprika.
6. Add the top layer: Sprinkle the remaining cheese over the zucchini, creating a cheese-zucchini-cheese sandwich structure.

Baking to Perfection

7. Bake: Place in the preheated oven for 14-15 minutes, or until the edges are golden brown and the cheese is bubbly and crispy.
8. Cool and cut: Allow to cool for 2-3 minutes, then carefully cut the baked layer in half using a sharp knife or pizza cutter to create two “bread” slices.

Assembly

9. Spread the base: On one zucchini “slice,” spread the avocado mayo and mustard evenly.
10. Layer the fillings: Add the sliced chicken, lettuce, tomato, red onion, and avocado in that order.
11. Finish and serve: Sprinkle with everything bagel seasoning, top with the second zucchini “bread” slice, and cut diagonally for easy handling.

Creative Variations to Try

Vegetarian Delight: Replace chicken with thick slices of grilled portobello mushroom, roasted red peppers, and fresh basil.

Mediterranean Style: Use feta cheese in the base, add cucumber, olives, and a drizzle of olive oil and balsamic vinegar.

Breakfast Breadwich: Top with a fried egg, crispy bacon, and fresh herbs for a morning twist.

Spicy Southwest: Add jalapeños, pepper jack cheese, and a chipotle mayo spread.

Italian Inspired: Use mozzarella and parmesan in the base, add prosciutto, fresh mozzarella, and pesto.

Storage and Make-Ahead Tips

The beauty of this recipe lies in its flexibility for meal prep. The zucchini-cheese base can be baked up to 2 days ahead and stored in an airtight container in the refrigerator. When ready to eat, simply reheat in a 350°F oven for 3-4 minutes or in an air fryer for 2 minutes to restore crispiness.

Important storage notes:

• Never microwave the zucchini base, as it will become soggy
• Store assembled sandwiches for no more than 2 hours to maintain texture
• Keep filling ingredients separate until ready to assemble

Expert Tips for Success

Choosing the right zucchini: Select firm, medium-sized zucchini with smooth skin. Avoid oversized ones, which tend to be watery and seedy.

Cheese selection matters: Sharp cheddar provides the best flavor and melting properties, but aged gruyere or gouda work beautifully too.

Moisture is the enemy: Take time to properly dry the zucchini slices—this step makes the difference between crispy and soggy results.

Don’t overfill: While it’s tempting to pile on ingredients, too many fillings can make the sandwich difficult to handle and may cause the delicate zucchini base to break.
