What Does Au Gratin Mean?

Gratin is a French culinary method that basically means you top whatever you like with a rich golden crust, commonly consisting of grated cheese, butter, egg and/or breadcrumbs. In the United States, we mainly call this recipe potatoes au gratin, but in France, they call it potatoes gratiné or gratin de pommes de terre.

The word “gratin” is said to come from the French word gratter, which means “to scrape” or “to grate.” Traditionally, potatoes au gratin are served in the same shallow dish they were baked in. Au gratin dishes can also be made with a variety of vegetables as well as pasta, meat and seafood. (1)

Potatoes au gratin ingredients - Dr. Axe
  • Fingerling potatoes: Fingerling potatoes are a good source of fiber, iron and vitamin C. (15) The vitamin C in the potatoes actually helps the body to absorb the iron better, too!
  • Goat’s milk: While typical potatoes au gratin recipes use heavy cream, this recipe includes goat’s milk, which is known for being easier to digest than cow’s milk, and many people with lactose intolerance do better with goat’s milk. Research using animal subjects has even shown that goat’s milk may be a better choice over cow’s milk as the first major source of protein after breast milk for babies. (16) Goat’s milk is also high in calcium, vitamin A and beneficial fatty acids. (17)
  • Fresh parsley: You may not think that a little bit of a fresh herb could offer much when it comes to vitamins and minerals, but the large amount of vitamin K in this recipe is actually thanks to parsley! Vitamin K is essential to proper blood clotting as well as bone metabolism. Parsley also contains iron, magnesium, phosphorus, potassium, zinc, folate, vitamin C and vitamin A. (18, 19)

Just make sure to keep it in the refrigerator, covered, and then bring it back to room temperature before you bake it.
