Ingredients

  • 8-10 cups sliced yellow squash
  • 1 medium sweet onion diced
  • 2 tsp salt divided
  • 2/3 cup mayonnaise
  • 1/2 cup sour cream
  • 1/2 cup butter, plus 2 Tbsp divided
  • 1/2 cup grated Parmesan cheese plus additional for the top as needed
  • 2 large eggs beaten
  • 1 tsp Italian seasoning
  • 1 tsp garlic powder or granulated garlic
  • 1 tsp black pepper
  • 2 cups grated sharp cheddar cheese
  • 2 cups dry herb stuffing mix [i.e. Pepperidge Farm or similar]

Instructions

  • Preheat the oven to 350°F. Spray a 13x9-inch baking dish with cooking spray, set aside.
  • In a large saucepan cover the sliced squash and diced onion with water. Season with 1 tsp salt. Cook for around 8-10 minutes until fork tender. Drain well.
  • Mash the cooked squash using a potato masher, leaving chunky. Add mayonnaise, sour cream, 6 tablespoons butter, grated Parmesan, beaten eggs, 1 tsp salt, seasonings and shredded cheddar cheese. Mix well.
  • Pour the squash mixture evenly into the casserole dish.
  • Melt the remaining 4 tablespoons butter and toss with the herb stuffing mix. Alternatively, you can substitute crushed Ritz crackers. Sprinkle over the top.
  • Sprinkle with 2 Tbsp additional Parmesan, if desired.
  • Place into the oven and bake for 40 minutes or until the top is golden brown.
  • Rest on the counter for 5-10 minutes then serve.

Notes

  • Stuffing Substitutions: Use crush Ritz crackers, club crackers or saltines for the topping. A buttery cracker topping works best.
  • Herbs: You may like to add fresh rosemary, thyme or chives to expand the flavor profile.
  • Squash: You can use this same casserole with half zucchini or all zucchini in place of yellow squash.
  • Cheese: You could use pepper jack cheese for spice or colby jack cheese for a mild creamy sauce taste.
  • Spice: You may opt to add crushed red pepper flakes or a few dashes of hot sauce for added spice.
