On the other hand, it shines just as brightly on a holiday table, sitting proudly next to roast meats and seasonal vegetables.
The dish’s timeless appeal comes from its balance: creamy layers of squash contrasted with a crunchy, buttery topping, all baked until golden. Whether you’re preparing a frozen squash casserole to save time or using fresh squash straight from a farmer’s market, the end result is always satisfying.
