Prep Time 10 min
Cook Time 30 min

6 tablespoons unsalted butter, divided
3 pounds yellow squash, sliced ¼-inch thick (from 5 medium squash)
1 medium-size yellow onion, chopped (about 1 ½ cups)
2 teaspoons kosher salt, divided
2 large eggs, lightly beaten
1 (8-oz.) container sour cream
4 ounces sharp Cheddar cheese, shredded (about 1 cup)
2 ounces Swiss cheese, shredded (about ½ cup)
½ cup mayonnaise
2 teaspoons chopped fresh thyme
½ teaspoon Sylvia’s Secret Seasoning 
2 sleeves round buttery crackers (such as Ritz), coarsely crushed 
1 ounce Parmesan cheese, shredded (about ¼ cup)

1) Preheat oven to 350°F. Melt 3 tablespoons of the butter in a large skillet over medium-high. Add squash, onion, and 1 teaspoon of the salt; cook, stirring often, until center of squash is just tender and liquid has evaporated, about 10 minutes. Transfer mixture to a colander set over a bowl. Drain 5 minutes; discard any liquid.
2) Stir together eggs, sour cream, Cheddar and Swiss cheeses, mayonnaise, thyme, pepper, and remaining 1 teaspoon salt in a large bowl. Gently fold in squash mixture. Spoon into a lightly greased 11- x 7-inch (2-quart) baking dish.
3) Microwave remaining 3 tablespoons butter in a medium-size microwavable bowl on HIGH until melted, about 25 seconds. Toss together crackers, Parmesan cheese, and melted butter until combined; sprinkle over casserole. Bake in preheated oven until golden brown, about 20 minutes.
