Ingredients

• 4 medium zucchini
• 1 teaspoon salt
• 2 tablespoons olive oil
• 1 medium onion
• 2 cloves garlic
• 0.5 cup heavy cream
• 4 ounces cream cheese
• 1.5 cups cheddar cheese
• 0.5 cup parmesan cheese
• 0.5 teaspoon black pepper
• 2 tablespoons fresh parsley

Directions

Step 1

Preheat the oven to 375°F (190°C).

Step 2

Slice the zucchini into thin rounds and place them in a bowl. Sprinkle with 1 teaspoon of salt and toss gently to coat evenly. Let them sit for about 10 minutes to draw out excess water.

Step 3

Meanwhile, finely chop the onion and mince the garlic. In a skillet over medium heat, add olive oil and sauté the onion for about 3-4 minutes until translucent. Add the garlic and sauté for another 1 minute until fragrant.

Step 4

In a small saucepan, combine the heavy cream and cream cheese over medium-low heat. Stir until the cream cheese is fully melted and smooth. Remove from heat.

Step 5

Pat the zucchini slices dry with a clean kitchen towel or paper towel to remove any moisture.

Step 6

In a large bowl, combine the zucchini, sautéed onions and garlic, cream mixture, 1 cup of cheddar cheese, 1/4 cup of parmesan cheese, and black pepper. Mix well to combine.

Step 7

Transfer the mixture into a greased 9x13 inch baking dish, spreading it evenly.

Step 8

Top with the remaining cheddar cheese and parmesan cheese.

Step 9

Bake in the preheated oven for about 25-30 minutes, or until the top is golden brown and bubbly.

Step 10

Remove from the oven and let it cool for 5 minutes. Garnish with freshly chopped parsley before serving.
