📝 Ingredients
- 4 medium zucchini, about 2 lb (900 g), sliced into 1/4-inch rounds
- 1 tsp salt, divided
- 2 tbsp olive oil
- 3 cloves garlic, minced
- 1 1/2 cups (360 ml) marinara sauce
- 1 tsp Italian seasoning
- 1/2 tsp black pepper
- 1/2 tsp red pepper flakes, optional
- 1 cup (100 g) shredded mozzarella cheese
- 1/2 cup (50 g) freshly grated Parmesan cheese
- 1/4 cup fresh basil leaves, chopped
- 2 tbsp fresh parsley, chopped, optional
Note: Choose a no-added-sugar marinara if you’re specifically following a low-carb or keto-style plan.
Directions
- Preheat the oven:
Heat the oven to 425°F (220°C). Lightly grease a large baking sheet and a 9×13-inch baking dish. - Slice and salt the zucchini — 5 minutes:
Slice zucchini into approximately 1/4-inch rounds. Arrange them on the baking sheet and sprinkle with 1/2 teaspoon salt. Let them sit for 10 minutes. - Remove excess moisture:
Pat the zucchini thoroughly with paper towels. This helps prevent a watery casserole. - Season the zucchini:
Toss the slices with olive oil, minced garlic, black pepper, Italian seasoning, and remaining salt. - Roast — 12–15 minutes:
Arrange zucchini in a single layer and roast at 425°F (220°C) for 12–15 minutes, turning halfway through. The slices should be tender with lightly browned edges. - Prepare the sauce:
While the zucchini roasts, stir the marinara sauce with red pepper flakes if using. - Lower the oven temperature:
Reduce the oven to 375°F (190°C). - Create the first layer:
Spread a thin layer of marinara over the bottom of the baking dish. Add a layer of roasted zucchini. - Add cheese:
Sprinkle with Parmesan and mozzarella. - Repeat the layers:
Continue layering marinara, zucchini, Parmesan, and mozzarella until all ingredients are used. Finish with a generous layer of cheese. - Bake — 18–20 minutes:
Bake at 375°F (190°C) until the sauce is bubbling and the cheese has melted. - Broil — 1–2 minutes:
Switch the oven to broil and cook for 1–2 minutes, watching carefully, until the cheese is golden brown. - Rest — 5–10 minutes:
Remove from the oven and allow the dish to rest for 5–10 minutes. This helps the layers settle and makes serving easier. - Garnish and serve:
Sprinkle with fresh basil and parsley. Serve warm.
