This Southern-style Squash Casserole from Paula Deen features tender yellow squash, sweet onions, sharp cheddar, and a rich sour cream base—topped with buttery Ritz crackers for the perfect crunch. It’s comfort food at its finest and a staple on any Southern table.
1 tablespoon vegetable oil
6 medium yellow squash, thinly sliced
1 large Vidalia onion, thinly sliced
1 tablespoon butter
½ cup grated Parmesan cheese
1 cup shredded sharp cheddar cheese
½ cup sour cream
Salt and freshly ground black pepper, to taste
1 sleeve buttery crackers (like Ritz), crushed
Preheat Oven:
Preheat your oven to 350°F (175°C). Lightly grease a 2-quart casserole dish.
Cook Vegetables:
In a large skillet, heat the vegetable oil over medium heat.
Add squash, onion, and butter. Cook until vegetables are soft (about 10 minutes), stirring occasionally.
Drain any excess liquid.
Mix Filling:
In a large bowl, combine cooked squash and onion with Parmesan, cheddar cheese, and sour cream.
Season with salt and pepper to taste. Mix until well combined.
Assemble Casserole:
Pour the squash mixture into the prepared baking dish and smooth the top.
Sprinkle the crushed crackers evenly over the top.
Bake:
Bake for 20–25 minutes or until the cracker topping is golden brown and the filling is bubbly.
Cool & Serve:
Let it rest for 5–10 minutes before serving. It sets up better and is easier to slice!
Want a bit of a kick? Add a pinch of cayenne or paprika.
You can substitute ricotta for sour cream if needed.
To make it ahead: Assemble (without cracker topping), refrigerate, and add crackers right before baking.
