Ingredients
This recipe makes 6 generous servings.
- For the Zucchini Layer:
- 3 medium zucchini (about 2 pounds total), thinly sliced into 1/4-inch rounds
- 1 teaspoon salt (for salting zucchini)
- 1 tablespoon olive oil
- 1/2 cup finely chopped yellow onion
- 2 cloves garlic, minced
- For the Creamy Cheese Mixture:
- 1 cup ricotta cheese (part-skim or whole milk)
- 1 large egg
- 1/2 cup grated Parmesan cheese, plus more for topping
- 1/4 cup chopped fresh parsley
- 1/4 cup chopped fresh basil
- 1/2 teaspoon black pepper
- 1/4 teaspoon salt
- For the Topping:
- 1/2 cup panko breadcrumbs
- 2 tablespoons melted unsalted butter
- 1/4 cup grated Parmesan cheese
Step-by-Step Instructions
Step 1: Prepare the Zucchini
First, slice your zucchini into uniform 1/4-inch rounds. Lay the slices out on paper towels or a clean kitchen towel. Sprinkle them evenly with 1 teaspoon of salt. Let them sit for 15-20 minutes. This step draws out excess moisture, preventing your casserole from becoming watery. After resting, gently blot the zucchini slices dry with more paper towels.
Small tip: Don’t skip the salting step! It’s key for a firm, flavorful casserole.
Step 2: Sauté the Aromatics
While the zucchini rests, heat the olive oil in a medium skillet over medium heat. Add the chopped yellow onion and cook until softened and translucent, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant. Remove from heat and set aside to cool slightly.
Small tip: Avoid browning the garlic; it can become bitter. Just cook until fragrant.
Step 3: Prepare the Cheese Mixture
In a medium bowl, combine the ricotta cheese, large egg, 1/2 cup grated Parmesan cheese, fresh parsley, fresh basil, black pepper, and 1/4 teaspoon salt. Mix everything together until well combined and creamy. This will be the delicious binder for your casserole.
Small tip: Use fresh herbs for the best flavor; they truly make a difference!
Step 4: Assemble the Casserole
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Arrange half of the dried zucchini slices in a single layer at the bottom of the dish, overlapping them slightly. Spread half of the sautéed onion and garlic mixture over the zucchini. Then, carefully spread half of the creamy cheese mixture evenly over the onion and garlic.
Small tip: A spatula works great for spreading the cheese mixture smoothly.
Step 5: Layer Again
Repeat the layering process: add the remaining zucchini slices, followed by the rest of the sautéed onion and garlic. Finish by spreading the remaining creamy cheese mixture over the top. Make sure it’s spread to the edges for even baking.
Small tip: Don’t press down too hard; keep the layers relatively light.
Step 6: Prepare the Topping
In a small bowl, combine the panko breadcrumbs, melted butter, and 1/4 cup grated Parmesan cheese. Toss with a fork until the breadcrumbs are evenly coated. Sprinkle this mixture generously over the top of the casserole. This will create a beautiful golden, crispy crust.
Small tip: Panko breadcrumbs give a much crispier topping than regular breadcrumbs.
Step 7: Bake the Casserole
Place the baking dish in the preheated oven. Bake for 35-40 minutes, or until the casserole is bubbly around the edges and the topping is golden brown and crispy. If the topping starts to brown too quickly, you can loosely cover it with foil for the last 10 minutes of baking.
Small tip: Check for bubbling around the edges to ensure it’s heated through.
Step 8: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for 10-15 minutes before serving. This resting period allows the casserole to set, making it easier to scoop and preventing it from falling apart. Slice into squares and serve warm!
Small tip: Resting also helps the flavors meld together even more beautifully.
Tips & Variations
- Gluten-Free Option: Easily make this gluten-free by swapping out the panko breadcrumbs for gluten-free panko breadcrumbs or crushed gluten-free crackers.
- Vegetarian Option: This recipe is already vegetarian! For a vegan version, use plant-based ricotta, a flax egg or egg substitute, and dairy-free Parmesan-style cheese.
- Add More Veggies or Protein: Feel free to sauté other finely diced vegetables like bell peppers, mushrooms, or spinach with the onion and garlic. For added protein, you could layer in cooked, crumbled turkey sausage or shredded chicken.
- Spicy Kick: If you love a little heat, add a pinch of red pepper flakes to the cheese mixture or sprinkle some on top before baking. A dash of hot sauce in the cheese mixture also works wonders.
- Herb Variations: Don’t limit yourself to just parsley and basil! Try adding fresh oregano, thyme, or a blend of Italian herbs to the cheese mixture for a different flavor profile.
