I am searching all over possible for that perfect vegetable casserole recipes apt as the holiday dinner casseroles. Although I am new to cooking, I am determined that I can do it. I want to make a butternut squash casserole that includes some fresh apples which is topped with the buttery spiced crumb topping with some brown sugar. Will you teach me to make my dream come true? Can I make the butternut squash and apple casserole simultaneously, how can I do so?
