Frequently Asked Questions
Can I use fresh vegetables instead of frozen?
Yes, you can use fresh vegetables. Just make sure to blanch them briefly in boiling water before adding them to the casserole to ensure they are tender. Adjust the cooking time accordingly to ensure everything is cooked through.
Is it possible to make this casserole ahead of time?
Absolutely! You can assemble the casserole a day in advance and store it covered in the refrigerator. Just remember to add a few extra minutes to the baking time if you're cooking it straight from the fridge.
Can I substitute the cheese for a dairy-free option?
Yes, you can use a dairy-free mozzarella cheese or nutritional yeast for a cheesy flavor. Just be aware that the texture and flavor may vary slightly, but it will still be delicious and suitable for a vegan diet.
