  • 1 pound yellow squash, sliced

  • 1 pound zucchini, sliced

  • ½ onion, diced

  • 1 cup shredded Cheddar cheese

  • ½ cup biscuit baking mix (such as Bisquick®)

  • ½ cup butter

  • 2 eggs

  • 1 tablespoon white sugar

  • 1 teaspoon salt

  • 10 saltine crackers, or as needed, crushed

  • ¼ cup bread crumbs


  1. Preheat oven to 325 degrees F (165 degrees C).

  2. Fill a large pot with water and bring to a rolling boil. Add yellow squash, zucchini, and onion; bring back to a boil, and cook vegetables until tender, about 15 minutes. Drain and transfer vegetables to a large bowl.

  3. Mix Cheddar cheese, baking mix, butter, eggs, sugar, and salt with the cooked vegetables using a large spoon; stir until butter has melted and baking mix has dissolved. Fold crushed crackers into the mixture until the liquid has been absorbed. Pour mixture into a 1 1/2-quart casserole dish; top with bread crumbs.

  4. Bake in the preheated oven until topping is lightly browned and cheese is melted, 30 minutes.
