Instructions

Preheat to 375°Fahrenheit (190°Celsius), grease a 2-quart dish, and prep the onion, cheddar, and crushed Ritz so everything is ready to assemble.
Wash and cut the yellow squash into ⅓-inch rounds, keeping them thick enough to hold their shape; set aside in a large bowl.
Sauté the diced onion in butter until soft and golden, then melt in the cream cheese to form a smooth, rich base.
Mix the onion-cream mixture with mushroom soup, the egg, half the cheddar, salt, and pepper, then gently coat the squash slices in the sauce.
Stir the crushed Ritz, melted butter, and remaining cheddar together until evenly coated to create a crunchy topping.
Spread the squash mixture in the dish, cover with the topping, and bake 20–25 minutes until bubbly and golden before serving warm.

Notes

Use fresh yellow squash for the best flavor: Fresh squash has a sweeter, tender texture that holds up well in the casserole. Avoid older or soft squash to prevent a watery dish.
Don’t skip the topping: The buttery, crunchy topping adds texture and makes the casserole extra satisfying. Panko or crushed crackers work best for that golden finish.
Pre-cook the squash slightly: Sautéing or steaming the squash before baking helps remove excess moisture. This keeps the casserole creamy without becoming soggy.
Season generously: Add salt, pepper, and your favorite herbs to bring out the natural flavor of the squash. Proper seasoning balances the creaminess and makes each bite delicious.
