A comforting and crispy zucchini casserole topped with buttery Ritz crackers and melted cheese, perfect as a quick and easy side dish.

Ingredients

Scale
  • 4 medium zucchinis, sliced thinly (about 4 cups)
  • 1 1/2 cups crushed Ritz crackers (about 30 crackers)
  • 2 cups shredded sharp cheddar cheese (optional mix with mozzarella)
  • 1 cup sour cream (full-fat or Greek yogurt as alternative)
  • 1/2 cup mayonnaise
  • 1/2 cup finely chopped onion (white or yellow)
  • 1 large egg, beaten
  • 1 teaspoon garlic powder
  • 1/2 teaspoon dried thyme (optional)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 3 tablespoons melted butter

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish with butter or non-stick spray.
  2. Wash and slice zucchinis into thin rounds about 1/8 inch thick. Place in a colander, sprinkle with a pinch of salt, and let sit for 15 minutes to draw out moisture.
  3. Crush Ritz crackers in a zip-top bag using a rolling pin until coarse crumbs form. Mix crumbs with melted butter and set aside.
  4. In a large bowl, combine sour cream, mayonnaise, beaten egg, garlic powder, dried thyme, salt, and black pepper. Stir until smooth.
  5. Add chopped onion and shredded cheese to the mixture and stir to combine.
  6. Pat dry zucchini slices with paper towels to remove excess moisture, then gently fold into the sour cream mixture without mashing.
  7. Transfer zucchini mixture to the prepared casserole dish and spread evenly.
  8. Sprinkle the buttery Ritz cracker crumbs evenly over the top.
  9. Bake uncovered for 35-40 minutes until topping is golden brown and casserole is bubbling around edges.
  10. Remove from oven and let rest for 5-10 minutes before serving.

Notes

Salt and drain zucchini to avoid watery casserole. Use coarse cracker crumbs mixed with melted butter for best crispy topping. Let casserole rest before serving for neat slices. Tent with foil if topping browns too fast.
