What You'll Need

  • 2 cups yellow summer squash, sliced
  • 1/2 cup mayonnaise
  • 1/2 cup chopped onion
  • 1 large egg, beaten
  • 1 teaspoon sugar
  • 1/2 teaspoon salt
  • 1/8 teaspoon pepper
  • 1/4 cup melted butter, divided
  • 3/4 cup shredded Cheddar cheese, divided
  • 2 tablespoons butter, cut into small pieces
  • 2 tablespoons melted butter
  • 1/2 cup soft bread crumbs
  • salt and pepper

How to Make It

  1. Slice the summer squash and add the squash to a saucepan. Cover with one inch of water. Heat on medium high heat until it is cooked and tender, adding more water as necessary to keep it from sticking on the bottom of the pan.
  2. Drain the squash and mash it.
  3. Butter a 1 to 1 1/2-quart casserole. Heat the oven to 350 F.
  4. In a bowl, blend the mashed squash with mayonnaise, chopped onion, beaten egg, salt, pepper, 2 tablespoons of melted butter, and the 1/2 cup of the cheddar cheese.
  1. Spoon the mixture into the prepared casserole.
  2. Top the casserole with the remaining 1/4 cup of shredded cheese.
  3. Toss the bread crumbs with the remaining 2 tablespoons of melted butter; spread over the casserole.
  4. Bake for 30 minutes, or until bubbly and lightly browned.
  5. Serve hot.

This casserole is a good side dish combining a starch and vegetables to serve with a meat entree, especially chicken. If you're serving fried chicken, roasted chicken, or grilled chicken breast, it will pair very well. It will also pair well with grilled or baked fish, including salmon. A fresh green salad will complement the meal.

Variations include adding chopped red peppers or green peppers with the onion, adding a little color as well as their flavor. You can spice it up by adding chilies as well.
