Ingredients

2 medium zucchinis, cut into ¼-inch thick rounds
1 tablespoon olive oil
½ teaspoon salt
½ teaspoon black pepper
½ teaspoon Italian seasoning
½ cup marinara sauce
½ cup shredded mozzarella cheese
¼ cup grated Parmesan cheese
¼ teaspoon red pepper flakes (optional, for spice)
Fresh basil leaves (for garnish)

Step-by-Step Instructions

1. Preheat & Prepare the Zucchini

Preheat your grill or grill pan to medium-high heat (375-400°F).
Slice the zucchinis into ¼-inch thick rounds.
Brush both sides with olive oil and season with salt, pepper, and Italian seasoning.

2. Grill the Zucchini

Place zucchini rounds directly on the grill.
Grill for 2-3 minutes per side, or until grill marks appear and they become slightly tender.
Remove from the grill and let them cool slightly.

3. Assemble the Stacks

Preheat oven to 400°F (200°C).
On a baking sheet, place half of the grilled zucchini rounds.
Add ½ teaspoon marinara sauce to each round, then sprinkle mozzarella cheese on top.
Place another zucchini round over the cheese, add more marinara, and top with Parmesan cheese.

4. Bake Until Golden

Bake in the oven for 5-7 minutes, or until the cheese is melted and bubbly.
Optional: Broil for 1-2 minutes for a crispy, golden cheese topping.

5. Garnish & Serve

Sprinkle with red pepper flakes and fresh basil leaves.
Serve immediately while warm and gooey!

✅ Customize It – Try adding ricotta or goat cheese for a richer flavor.
✅ Meal Prep Friendly – Grill zucchini in advance and assemble stacks when ready to bake!
