This fabulous gratin is made even more indulgent with a bechamel — a French white sauce made from a roux (flour and butter) and cold milk.

You can easily substitute spinach or other greens, but the bright red of Swiss chard’s stems makes this dish very visually appealing.

Ingredients:

  • ½ bunch Swiss or rainbow chard
  • 1 large Yukon Gold potato, peeled
  • 1 whole shallot, minced
  • 1 Tbsp. cold milk
  • 2 ½ Tbsp. unsalted butter
  • ¼ cup all-purpose flour
  • 2 Tbsp. extra virgin olive oil
  • ½ tsp. kosher salt
  • ½ tsp. freshly ground pepper
  • ½ tsp. nutmeg
  • ¼ cup Parmesan cheese, freshly grated

done
Bake until cheese is bubbling and browned

Instructions:

  • Preheat oven to 450 degrees, positioning rack near top of oven. Rinse the chard thoroughly in cold water. Pat dry with paper towels. Chop into 1-inch pieces.

  • Heat 1 Tbsp. olive oil in a skillet over medium-high heat. Add potatoes, salt, and pepper and sauté for 5 minutes, stirring constantly.

  • Add chard and remaining olive oil, then continue to cook until the stems are nice and soft, about 7-8 minutes. If the liquid evaporates and the chard starts sticking, deglaze the pan with a little water.

  • Toss in the shallots and cook another 2 minutes, until shallots are translucent. Remove from heat.

  • In a small pot, melt butter over low heat. Remove from heat and add three or four pinches of flour. Whisk immediately to combine evenly, then return to heat. Cook for 1 minute, until the mixture thickens.

  • Add cold milk, whisk, and cook some more. Add more milk and repeat. Bring to a boil and cook another minute, whisking constantly.

  • Add small pinches of pepper, nutmeg, and salt. Taste, checking for any trace of an uncooked-flour flavor. Adjust seasoning.

  • Butter a gratin dish or small baking pan. Add chard and potato mixture, then pour bechamel on top. Sprinkle generously with the grated Parmesan.

  • Set the gratin or baking dish on a baking sheet (this makes it easier to remove from the oven.) Bake for 10-12 minutes, until the cheese is bubbling and browned.
