Zucchini and Squash Casserole recipe
Print Recipe

Zucchini and Squash Casserole is a baked dish that combines sliced zucchini and yellow squash with cheese, herbs, and a light sauce. It’s typically topped with breadcrumbs or crushed crackers to add a golden, crispy finish. The result is a creamy, tender, and flavorful casserole that pairs perfectly with grilled meats, roasted chicken, or can be enjoyed on its own as a vegetarian main.

Ingredients

Scale

  • 2 medium zucchinis, sliced into thin rounds

  • 2 medium yellow squashes, sliced into thin rounds

  • 1 small onion, finely chopped

  • 2 tablespoons olive oil or butter

  • 1 cup shredded cheddar cheese (or mozzarella)

  • ½ cup grated Parmesan cheese

  • ½ cup sour cream or Greek yogurt

  • 1 teaspoon garlic powder

  • ½ teaspoon dried thyme or Italian seasoning

  • Salt and black pepper to taste

  • ½ cup breadcrumbs or crushed Ritz crackers

  • 1 tablespoon melted butter (for topping)

  • Fresh parsley, for garnish

Instructions

Step 1: Preheat and prep the vegetables

Preheat your oven to 375°F (190°C). Lightly grease a medium baking dish. Slice zucchini and squash evenly and pat them dry with a paper towel to remove excess moisture.

Step 2: Sauté the vegetables

In a skillet, heat olive oil or butter over medium heat. Add onions, zucchini, and squash, and cook for 5–7 minutes until just tender. Season with salt, pepper, and garlic powder. Remove from heat and let cool slightly.

Step 3: Combine the creamy mixture

In a bowl, mix sour cream (or Greek yogurt), shredded cheddar, half the Parmesan cheese, and thyme. Stir until well combined, then gently fold in the sautéed vegetables.

Step 4: Assemble the casserole

Transfer the mixture to the greased baking dish. Spread evenly, then sprinkle the remaining Parmesan cheese on top.

Step 5: Add the crunchy topping

Combine breadcrumbs (or crushed crackers) with melted butter and sprinkle over the top for that perfect golden crust.

Step 6: Bake until bubbly

Bake for 25–30 minutes or until the top is golden brown and the casserole is bubbling around the edges.

Step 7: Garnish and serve

Remove from the oven and let it cool for 5 minutes. Garnish with chopped parsley and serve warm.
