Summer Squash Gratin is a savory baked dish featuring sliced yellow summer squash (like zucchini or crookneck) layered with cheese, cream, and often a breadcrumb or Parmesan topping. It originates from American home cooking, particularly popular in the Southern United States during summer when squash is abundant. The dish is a comforting, creamy side that highlights fresh seasonal produce.
This gratin is moderate in carbohydrates from the squash and any breadcrumb topping, but higher in fat due to the cheese and cream base. It provides a good source of Vitamin C, potassium, and calcium, with a typical serving containing around 250-350 calories.

Culturally, it's a classic example of 'farm-to-table' comfort food before the term existed, making use of summer's prolific squash harvest. Nutritionally, the high water content of squash makes it a lighter alternative to potato gratins, while the cheese adds significant protein and fat.
