1 9x13-inch casserole


  • 1 pound carrots, sliced

  • 3 zucchinis, sliced

  • ½ cup mayonnaise

  • 2 tablespoons grated onion

  • ¾ teaspoon prepared horseradish

  • ½ teaspoon salt

  • ½ teaspoon ground black pepper

  • ½ cup Italian bread crumbs

  • ¼ cup butter, melted


  1. Preheat the oven to 375 degrees F (190 degrees C). Lightly grease a 9x13-inch baking dish.

  2. Place carrots into a medium pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until carrots are just tender, about 15 minutes. Use a slotted spoon to transfer carrots to a bowl. Add zucchinis to simmering water in the pot and cook until tender, 2 to 3 minutes. Transfer zucchinis to the bowl with carrots. Drain water from the pot, reserving about 1/4 cup cooking liquid.

  3. Add mayonnaise, onion, horseradish, salt, and black pepper to a large bowl. Stir in reserved cooking liquid. Mix carrots and zucchinis into mayonnaise mixture until well combined; pour mixture into the prepared baking dish.

  4. Mix bread crumbs and melted butter in a small bowl until combined; sprinkle over vegetable mixture.

  5. Bake in the preheated oven until bread crumbs are lightly browned, about 15 minutes.
