1. Old Fashioned Squash Casserole Recipe (Yield: 12 Servings)
Ingredients
- 2 tablespoons butter
- 4 cups sliced yellow squash
- 1 medium onion, chopped
- 2 large eggs
- 1 cup grated cheddar cheese
- 1 cup milk
- 2 tablespoons butter, melted
- ¼ teaspoon cayenne pepper (optional)
- ½ teaspoon kosher salt
- ½ teaspoon ground black pepper
- 1 sleeve Ritz crackers
Instructions
Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick cooking spray.
Wash the yellow squash and slice it into ¼-inch rounds so the pieces cook evenly.
Melt 2 tablespoons of butter in a large skillet over medium heat. Add the chopped onion and sliced squash. Cook for 10 to 12 minutes, stirring occasionally, until the squash is tender and most of the moisture has evaporated. If excess liquid remains in the skillet, continue cooking for a few more minutes until it has mostly evaporated. This step helps prevent a watery casserole.
Remove the skillet from the heat and allow the squash mixture to cool for about 10 minutes.
In a large mixing bowl, whisk together the eggs, milk, grated cheddar cheese, salt, black pepper, and cayenne pepper if using.
Add the cooled squash and onion mixture to the bowl and gently stir until everything is evenly combined.
Pour the mixture into the prepared baking dish and spread it into an even layer.
Crush the Ritz crackers into coarse crumbs using your hands or a rolling pin. Mix the cracker crumbs with the remaining 2 tablespoons of melted butter until evenly coated.
Sprinkle the buttered cracker crumbs evenly over the top of the casserole.
Bake uncovered for 35 to 40 minutes, or until the filling is fully set and the cracker topping is golden brown.
Allow the casserole to rest for 10 minutes before serving. This helps the filling firm up slightly and makes serving easier.
2. Tips for Perfect Old Fashioned Squash Casserole
Cook the squash until most of its moisture has evaporated before assembling the casserole. Yellow squash naturally contains a lot of water, and removing excess moisture is the key to a creamy casserole instead of a watery one.
Let the cooked squash cool slightly before mixing it with the eggs. Adding hot vegetables directly to the egg mixture can cause the eggs to cook prematurely.
Grate your own cheddar cheese instead of using pre-shredded cheese. Freshly grated cheese melts more smoothly and creates a creamier filling.
Keep the Ritz cracker topping coarse rather than crushing it into fine crumbs. Larger pieces stay crisp during baking and create a better texture.
Allow the casserole to rest for about 10 minutes after baking. This gives the filling time to set, making it easier to slice and serve without falling apart.
3. Frequently Asked Questions
Can I make squash casserole ahead of time?
Yes. Assemble the casserole without the cracker topping, cover, and refrigerate for up to 24 hours. Add the buttered cracker topping just before baking to keep it crispy.
How do I keep squash casserole from becoming watery?
Cook the squash long enough for excess moisture to evaporate before combining it with the other ingredients. Allowing the cooked squash to cool briefly before mixing also helps reduce excess liquid.
Can I freeze squash casserole?
Yes. Bake the casserole without the cracker topping, cool completely, and freeze for up to 2 months. Add fresh buttered crackers before reheating for the best texture.
What can I serve with squash casserole?
This casserole pairs well with fried chicken, roasted turkey, baked ham, pork chops, meatloaf, grilled steak, or barbecue.
Can I use zucchini instead of yellow squash?
Yes. Zucchini works well, but it contains slightly more moisture than yellow squash. Be sure to cook it until most of the liquid has evaporated before assembling the casserole.
