How to Make Squash Casserole
Step 1: Preheat the Oven
Preheat your oven to 350º F. This sets the right temperature for cooking your casserole evenly and thoroughly.
Step 2: Sauté the Vegetables
Melt 2 tablespoons of butter in a medium skillet over medium-low heat. Add the sliced squash and chopped onion, cooking until they become tender and fragrant, which should take about 5 to 7 minutes.
Step 3: Prepare the Egg Mixture
In a large bowl, crack the eggs and lightly whisk them. Then, add the grated cheddar cheese and milk, whisking everything together until it forms a smooth mixture.
Step 4: Combine the Ingredients
Add the cooked squash and onion mixture to the egg mixture. Stir everything together until well combined, ensuring the vegetables are evenly distributed.
Step 5: Add Remaining Butter and Seasoning
In the same skillet, melt the remaining 2 tablespoons of butter. Pour this butter into the squash casserole mixture. Add the optional cayenne pepper, along with kosher salt and black pepper. Stir well to incorporate all the flavors.
Step 6: Prepare to Bake
Spray a 9×13 casserole dish with cooking spray. Pour the squash casserole mixture into the dish and spread it evenly.
Step 7: Top with Crackers
Sprinkle the crushed Ritz crackers evenly over the top of the casserole. This will create a deliciously crunchy topping.
Step 8: Bake the Casserole
Place the dish in the preheated oven and bake for 45 minutes. The top should be lightly browned, and the casserole shouldn’t jiggle when moved.
Step 9: Serve
Once baked, allow the casserole to sit for about 3 minutes before serving. This waiting time helps set the dish, making it easier to cut and serve.
Pro Tips from My Kitchen
✓ Use Fresh Squash – Fresh yellow squash tastes better and has a better texture compared to frozen. Ensure you slice them evenly for uniform cooking.
✓ Don’t Overcook the Vegetables – Sauté the squash and onions just until tender. This prevents them from becoming mushy in the casserole.
✓ Experiment with Cheeses – Feel free to mix different cheeses like Monterey Jack or mozzarella for a unique flavor. Each type will add its own twist.
✓ Let it Rest – Allowing the casserole to rest after baking firm up the texture and makes it easier to serve.
✓ Make it Ahead – You can prepare the casserole a day in advance, cover it tightly, and store in the fridge. Just bake it the next day, adding a few extra minutes to the timing if it's cold from refrigeration.
