Ingredients

Scale

Vegetables

  • 3 cups yellow squash, thinly sliced
  • 3 cups zucchini, thinly sliced
  • 1 medium onion, finely diced

Cheeses

  • 2 cups sharp cheddar cheese, shredded (reserve 1/2 cup for topping)
  • 1/2 cup Parmesan cheese, grated

Wet Ingredients & Seasonings

  • 1/2 cup mayonnaise
  • 1/2 cup sour cream
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper

Topping

  • 1 cup bread crumbs
  • 2 tablespoons butter

Instructions

  1. Prepare Squash and Vegetables: Wash and slice the yellow squash and zucchini evenly into thin rounds. Dice the onion finely to ensure every bite has balanced flavors.
  2. Combine the Wet Ingredients: In a large mixing bowl, blend together mayonnaise, sour cream, garlic powder, salt, and pepper until smooth and creamy.
  3. Mix Squash and Cheese: Fold the sliced squash, zucchini, and onions into the wet mixture, then stir in most of the sharp cheddar cheese, reserving some for the topping.
  4. Assemble the Casserole: Transfer the squash mixture into a greased baking dish, spreading evenly. Sprinkle the remaining cheddar and Parmesan cheese evenly on top.
  5. Prepare the Bread Crumb Topping: In a small pan, melt butter and toss in the bread crumbs until golden brown, then sprinkle this crispy layer over the cheese-topped casserole.
  6. Bake to Perfection: Bake the casserole in a preheated oven at 350°F (175°C) for about 40 minutes or until the top is bubbly and golden, and the squash is tender.

Notes

  • Use fresh, firm squash for best texture and flavor.
  • Gently combine ingredients to avoid making the squash mushy.
  • Use good-quality sharp cheddar cheese for richer taste and better melt.
  • Toast bread crumbs separately for a crunchier topping.
  • Allow casserole to rest slightly before serving to set and slice cleanly.
