Tips & Substitutions

For a creamier texture, consider using Greek yogurt instead of mayonnaise. You can also swap yellow squash for zucchini for a different flavor. If you want to add some spice, try incorporating a pinch of cayenne pepper into the mixture. Be sure to adjust cooking time if you use a larger casserole dish, as it may need longer to bake through.

Serving Suggestions

This Raw Squash Casserole makes a delightful side dish for grilled meats or a vegetarian main course. Serve it alongside a fresh salad or with crusty bread. For a more filling meal, pair it with protein, such as roasted chicken or baked fish. It pairs beautifully with Spiced Zucchini Bread for a comforting meal.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in a preheated oven at 350°F for about 15-20 minutes, or until heated through. You can also microwave individual portions, but the oven method will keep the topping crispy.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, you can prepare the casserole a day in advance. Assemble the ingredients and cover it tightly with plastic wrap or foil. Refrigerate overnight, and bake it right before serving. You may need to add a few extra minutes to the baking time if it’s cold from the fridge.

What can I substitute for the grated cheese?

If you're looking for a cheese alternative, nutritional yeast can provide a cheesy flavor without dairy. Alternatively, you can use a dairy-free cheese for a vegan option. Just ensure that whatever substitute you choose melts well to achieve the desired texture.

Can I add other vegetables to the casserole?

Absolutely! Feel free to add other vegetables like bell peppers, mushrooms, or even spinach to enhance the flavor and nutrition. Just make sure to chop them finely and adjust the cooking time if necessary, as different vegetables may require different cooking times.
