Potato and Chard Stalk Gratin Recipe (2024)

Ingredients

Yield:Serves four

• 1pound small boiling potatoes, scrubbed
• Salt to taste
• 1pound wide Swiss chard stems from 1 large or 2 smaller bunches, trimmed and cut crosswise into ½ inch thick slices
• 1garlic clove, halved
• 2tablespoons extra virgin olive oil
• 2tablespoons finely chopped shallot or onion optional
• 2tablespoons all-purpose flour
• 2cups low-fat (1 percent or 2 percent) milk
• Freshly ground white or black pepper
• 1teaspoon thyme leaves
• 1ounce Gruyère, grated ¼ cup

Preparation

1. Step

   1

   Place the potatoes in a saucepan, and cover with water. Add ½ teaspoon salt, and bring to a boil. Reduce the heat to medium, and boil gently until tender, 10 to 20 minutes, depending on the size of the potatoes. Add the chard stalks to the pot, and simmer for another five minutes until crisp-tender. Drain, and retain the cooking liquid if you prefer to use it instead of milk for the béchamel. Cut the potatoes into quarters or halves, depending on their size.

2. Step

   2

   Preheat the oven to 425 degrees. Rub a 2-quart baking dish or gratin with the cut clove of garlic, and brush with olive oil.

3. Step

   3

   Make the béchamel. Heat the oil over medium heat in a heavy medium saucepan. Add the shallot or onion, and cook, stirring, until softened, about three minutes. Stir in the flour, and cook, stirring, for about three minutes until smooth and bubbling but not browned. It should have the texture of wet sand. Whisk in the milk all at once, and bring to a simmer, whisking all the while, until the mixture begins to thicken. Turn the heat to very low and simmer, stirring often with a whisk and scraping the bottom and edges of the pan with a rubber spatula, for 10 to 15 minutes until the sauce is thick and has lost its raw flour taste. Season with salt and pepper. Strain while hot into a heatproof bowl or a Pyrex measuring cup.

   Bake 20 to 25 minutes until bubbling and beginning to brown on the top. Serve hot.

Tip

• Advance preparation: You can make a béchamel up to a day ahead of using it; keep it in the refrigerator. If you lay a sheet of plastic or wax paper directly on top, there is less chance that a skin will form. Even if it does, you can get rid of it by whisking vigorously when you reheat the béchamel. Then the sauce should be as smooth as it was when you made it. Thin out if necessary with milk or stock. You can cook the potatoes and chard stalks several hours ahead of serving. Assemble the gratin just before you cook it.
