Ingredients

Scale
  • 4 medium zucchinis, sliced thinly (about 4 cups)
  • 4 tablespoons unsalted butter, melted
  • 1.5 cups Ritz crackers, crushed
  • 1 cup sour cream
  • 1.5 cups shredded cheddar cheese (about 6 ounces)
  • ½ cup grated Parmesan cheese
  • 1 small yellow onion, finely chopped
  • 2 cloves garlic, minced
  • 2 tablespoons all-purpose flour
  • 1 cup milk (whole or 2%)
  • Salt and black pepper to taste
  • 1 tablespoon chopped fresh parsley or chives (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease your 9×13-inch baking dish with butter or non-stick spray.
  2. Wash and slice the zucchini into thin rounds, roughly ¼-inch thick. If zucchinis are watery, sprinkle with salt and let sit for 10 minutes, then pat dry.
  3. In a medium saucepan, melt 4 tablespoons of butter over medium heat. Add chopped onion and minced garlic, sauté until fragrant and translucent (3-4 minutes).
  4. Stir in 2 tablespoons of flour and cook for another minute to form a roux.
  5. Slowly whisk in 1 cup of milk, stirring until thickened and smooth (3-5 minutes). Remove from heat and add sour cream, shredded cheddar, and Parmesan cheese. Stir until cheeses melt and season with salt and pepper.
  6. Transfer sliced zucchini to a large mixing bowl. Pour creamy cheese sauce over zucchini and gently fold to coat evenly. Add fresh herbs if using.
  7. Pour zucchini mixture into prepared baking dish, spreading evenly. In a small bowl, combine crushed Ritz crackers with 2 tablespoons melted butter and sprinkle over casserole.
  8. Bake uncovered for 30-35 minutes until topping is golden brown and casserole is bubbly.
  9. Let casserole rest for 5-10 minutes before serving to set and deepen flavors.

Notes

If zucchinis are watery, salt and drain before mixing to avoid sogginess. Crush Ritz crackers by hand for texture. Tent casserole with foil if topping browns too quickly. Rest casserole before serving for best texture.
