The Squash Casserole with Ritz Crackers is a baked Southern side dish featuring yellow squash and onions combined in a creamy, cheesy base, topped with crushed buttery crackers. This casserole is the definition of comfort food — soft and creamy inside, with a crispy, golden crust that adds texture and flavor. It’s a versatile recipe that pairs beautifully with nearly any main course.
6 cups yellow squash, sliced
1 medium onion, finely chopped
1 cup shredded cheddar cheese
1 cup crushed Ritz crackers (plus more for topping)
½ cup sour cream
1 can (10.5 oz) cream of chicken soup (or mushroom soup for vegetarian version)
2 tablespoons butter
1 teaspoon garlic powder
Salt and black pepper, to taste
2 tablespoons melted butter (for topping)
Preheat oven: Set oven to 350°F (175°C) for even baking.
Cook the vegetables: In a large skillet, melt butter and sauté squash and onions for 8–10 minutes until tender.
Drain excess water: Remove from heat and drain well to prevent a soggy casserole.
Mix the base: In a large bowl, combine cooked squash, cream of chicken soup, sour cream, cheddar cheese, garlic powder, salt, and pepper.
Add crackers: Stir in crushed Ritz crackers to thicken the mixture.
Prepare the topping: Mix the remaining crushed Ritz crackers with melted butter.
Assemble the casserole: Pour the squash mixture into a greased baking dish and sprinkle the cracker topping evenly.
Bake: Bake uncovered for 25–30 minutes until golden brown and bubbly.
Cool before serving: Let the casserole rest for 5 minutes before serving for best texture.
