Southern squash casserole turns humble yellow squash into a creamy holiday side with cheddar and a crisp buttery cracker topping. The flavor stays vegetable-forward instead of tasting heavy.
The most important step is cooking off excess moisture before the casserole is assembled. Squash holds a lot of water, and draining it well prevents a soupy center.
What You’ll Need Before You Start
- Large skillet
- 9×13-inch or 2½-quart baking dish

ShiMuv Holiday Recipe
Ingredients
- 3 pounds yellow squash, sliced ¼ inch thick
- 1 medium yellow onion, diced
- 4 tablespoons unsalted butter, divided
- 1 teaspoon kosher salt, divided
- ½ teaspoon black pepper
- 2 large eggs
- ½ cup sour cream
- 1 cup shredded sharp cheddar
- 1½ cups crushed buttery crackers
- 2 tablespoons chopped parsley
How to Make It
- Heat the oven to 375°F and butter a 2½-quart baking dish. Slice the squash evenly so thin pieces do not dissolve before thicker ones soften.
- Melt 2 tablespoons butter in a large skillet over medium heat. Add onion and cook 3 minutes, then add squash, ½ teaspoon salt, and pepper.
- Cook 10–12 minutes, stirring often, until the squash is tender but not falling apart. Increase the heat slightly near the end so released moisture can evaporate.
- Transfer the squash mixture to a colander and drain 5 minutes, pressing very gently to remove excess liquid without mashing the vegetables.
- Whisk eggs, sour cream, remaining salt, and half the cheddar. Fold in the drained squash and onion, then spread into the baking dish.
- Mix cracker crumbs with the remaining 2 tablespoons melted butter and the remaining cheddar. Scatter evenly over the casserole.
- Bake 25–30 minutes until the edges bubble, the topping is golden, and the center reaches at least 160°F.
- Rest 10 minutes before serving so the creamy filling sets slightly. Finish with parsley just before bringing it to the table.
Recipe tip: Drain the cooked squash before adding dairy and eggs; trapped vegetable moisture is the main reason squash casserole turns watery.
Food safety: Because the casserole contains eggs, bake the center to at least 160°F. Refrigerate leftovers within 2 hours.
