Step 6: Prepare the Baking Dish

Preheat your oven to 350°F (175°C).

Lightly grease a 9×13-inch baking dish with butter or cooking spray.

Transfer the squash mixture into the dish and spread it evenly.

Smooth the top with a spatula.

Step 7: Make the Crispy Topping

In a small bowl, combine:

• Crushed buttery crackers
• Melted butter
• Reserved cheddar cheese

Mix until the cracker crumbs are evenly coated with butter.

This topping creates the signature golden crust that makes classic squash casserole so delicious.

Step 8: Add the Topping

Sprinkle the cracker mixture evenly over the squash filling.

Make sure the entire surface is covered so every serving gets a crispy topping.

Step 9: Bake the Casserole

Place the casserole in the preheated oven.

Bake for 30–40 minutes until:

• The filling is set.
• The cheese is melted.
• The topping becomes golden brown.
• The edges are slightly bubbling.

If the topping browns too quickly, loosely cover the dish with aluminum foil during the final minutes.

Step 10: Rest Before Serving

Remove the casserole from the oven and allow it to rest for 10 minutes.

This helps the filling firm up slightly and makes it easier to serve.

Garnish with fresh parsley before bringing it to the table.

Helpful Tips for the Best Squash Casserole

Remove excess moisture

Squash naturally contains a lot of water. Salting and draining it before cooking prevents a watery casserole.

Do not overcook the squash

Cook it until tender but still holding its shape.

Use freshly shredded cheese

Freshly grated cheese melts more smoothly than pre-shredded varieties.

Make the topping extra crispy

Add a little extra melted butter to the cracker topping for a richer golden crust.

Let it rest

Allowing the casserole to sit after baking improves the texture.

Delicious Variations

Add cooked, crumbled bacon for a smoky flavor.

Vegetable Version

Add zucchini, bell peppers, or mushrooms for extra flavor.

Herb Version

Add fresh thyme, basil, or rosemary for a garden-inspired taste.

Healthier Version

Replace mayonnaise with Greek yogurt and reduce the cheese slightly.

Storage and Reheating

Store leftover squash casserole in an airtight container in the refrigerator for up to 4 days.

To reheat:

• Warm individual portions in the microwave.

For the crispiest topping, reheating in the oven is recommended.
