A classic French dish, potato gratin combines with the American favorite, broccoli-cheese casserole, for a tasty twist on both. Make sure all the potato slices are about the same thickness so they cook evenly.
6 cups chopped broccoli florets (about 1 pound)
3/4 cup minced shallots (about 4 large)
2 tablespoons Dijon mustard
1 teaspoon chopped fresh thyme
1/2 teaspoon minced garlic
1/8 teaspoon ground nutmeg
3/4 teaspoon salt, divided
1/2 teaspoon freshly ground black pepper
2 pounds peeled Yukon gold potatoes, cut into 1/8-inch-thick slices
3 tablespoons all-purpose flour
1 1/2 cups 2% reduced-fat milk
1 1/4 cups fat-free, less-sodium chicken broth
2 tablespoons chilled butter, cut into small pieces
3/4 cup (3 ounces) shredded Gruyère cheese
How to Make It
Preheat oven to 375°.
Combine first 6 ingredients in a large bowl. Sprinkle with 1/2 teaspoon salt and pepper; toss to combine.
Layer one-third of potato slices in a 13 x 9-inch baking dish coated with cooking spray, overlapping to fit; top with half of broccoli mixture. Repeat layers, ending with potato. Sprinkle evenly with remaining 1/4 teaspoon salt.
Place 3 tablespoons flour in a medium bowl. Gradually add milk, stirring constantly with a whisk; stir in broth. Pour milk mixture over potato mixture. Top evenly with butter. Cover and bake at 375° for 1 hour. Uncover; sprinkle evenly with cheese. Bake 25 minutes or until browned. Cool on a wire rack 10 minutes.
It was a disappointment. The bottom of the dish was soaking in a soup-like sauce, while the top part remained dry. The taste was not my favorite either, the mustard did not blend well. I don''t even have any ideas how to improve this recipe.
Just made this for dinner last night and everyone liked it. The sauce did not thicken very much - however I made a separate dish for my husband, who has to eat gluten free, with corn starch rather than flour and it worked beautifully. Next time, I will use corn starch instead!
