Ingredients

• 4 medium zucchini
• 1 medium onion
• 1 teaspoon salt
• 3 tablespoons butter
• 2 tablespoons all-purpose flour
• 1.5 cups milk
• 1 cup shredded cheddar cheese
• 1 cup breadcrumbs
• 0.5 cup grated Parmesan cheese
• 2 tablespoons olive oil
• 0.5 teaspoon black pepper
• 0.5 teaspoon garlic powder

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Wash the zucchini and slice them into thin rounds, about 1/4 inch thick. Dice the onion.

Step 3

Bring a large pot of water to boil. Add the zucchini slices and 1/2 teaspoon of salt, then blanch for 2 minutes. Drain and set aside.

Step 4

In a large skillet over medium heat, melt 2 tablespoons of butter. Add the diced onion and sauté until softened, about 5 minutes.

Step 5

Sprinkle the flour over the onions and stir well, cooking for 1 minute to remove the raw flour taste.

Step 6

Slowly pour in the milk, whisking constantly to avoid lumps. Cook for 2-3 minutes, until the mixture thickens.

Step 7

Stir in the shredded cheddar cheese, remaining 1/2 teaspoon of salt, black pepper, and garlic powder. Mix until the cheese is melted and the sauce is smooth.

Step 8

In a greased 9x13-inch baking dish, layer half of the zucchini slices, then pour half of the cheese sauce over them. Repeat with the remaining zucchini and sauce.

Step 9

In a small bowl, combine the breadcrumbs, grated Parmesan cheese, and olive oil. Mix until the breadcrumbs are evenly coated.

Step 10

Sprinkle the breadcrumb mixture evenly over the top of the casserole.

Step 11

Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbling around the edges.

Step 12

Let the casserole rest for 5 minutes before serving. Enjoy!
