This Potato Turnip Mushroom Gratin is an example of a traditionally rich holiday dish that Jeanette Chen of Jeanette’s Healthy Living has lightened up with a few key ingredients. First. by using half turnips and half potatoes, this gratin is lower in carbohydrates than the standard potato gratin. Although the texture and taste of turnips are different from potatoes (they’re firmer and have a stronger flavor), the color is the same, so this half and half mixture is a great way to sneak in some healthier vegetables. Turnips are high in dietary fiber and vitamin C too, so it’s makes an excellent swap in for potatoes. Jeanette used a food processor to slice the turnips and potatoes which makes prep time much shorter. You can also use thin sliced carrots in place of some of the turnips or potatoes.
