Potatoes Au Gratin Gruyère -- Because the Kitchen Holds Structure and Grows All at Once

Jack's garden operation grows more ambitious every year. The greenhouse, the market sales, the Farm Fund jar that now holds over three hundred dollars. He's 12 and he farms the way some kids play video games — obsessively, joyfully, with the deep understanding that this is not a hobby but a vocation wearing a hobby's clothes.

Thursday was tater tot hotdish, because Thursday is always tater tot hotdish and the schedule doesn't change for anything — not pandemics, not loss, not the passage of years. The tater tots go in at 375 and come out golden and the family eats them and the eating is the Thursday and the Thursday is the structure and the structure holds. But I also made cherry tomato pasta earlier this week, because the kitchen doesn't only look backward. The kitchen grows.

The garden at peak production — tomatoes by the bushel, corn taller than Jack (which is saying something now, the boy is tall), peppers in every color, the zucchini in its annual attempt to conquer the neighborhood. I've left three on the neighbors' porch. They know. Everyone knows. The zucchini phase is endured, not discussed.

Thursday’s tater tots are non-negotiable — they always have been, and I hope they always will be — but that doesn’t mean the kitchen stops reaching. When Jack hauled in another basket of tomatoes and I found myself with a quiet afternoon and a block of Gruyère I’d been saving for something worthy, Potatoes Au Gratin felt exactly right: the same deep comfort as a hotdish, but dressed up a little, like the kitchen had decided to grow too. It’s the dish I make when I want the table to feel both rooted and alive.

Potatoes Au Gratin Gruyère

Prep Time: 20 minutes | Cook Time: 65 minutes | Total Time: 1 hour 25 minutes | Servings: 6

Ingredients

• 2 1/2 lbs Yukon Gold potatoes, peeled and sliced 1/8-inch thick
• 2 cups Gruyère cheese, freshly grated, divided
• 1 1/2 cups heavy cream
• 1/2 cup whole milk
• 3 cloves garlic, minced
• 2 tablespoons unsalted butter, plus more for the dish
• 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
• 1/2 teaspoon freshly grated nutmeg
• 1 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper
• Fresh parsley, chopped, for garnish

Instructions

1. Preheat and prep. Preheat your oven to 375°F. Butter a 2-quart (9x13-inch or equivalent) baking dish generously and set aside.
2. Make the cream sauce. In a medium saucepan over medium heat, melt the butter. Add the garlic and thyme and cook, stirring, for about 1 minute until fragrant. Pour in the heavy cream and milk, then add the nutmeg, salt, and pepper. Heat until just beginning to simmer, then remove from heat.
3. Layer the potatoes. Arrange one-third of the potato slices in an overlapping layer in the bottom of the prepared dish. Pour one-third of the cream mixture over the top and sprinkle with 1/2 cup of the Gruyère. Repeat with two more layers, ending with the remaining cream. Reserve the final 1/2 cup of Gruyère for the top.
4. Cover and bake. Cover the dish tightly with foil and bake for 45 minutes, until the potatoes are nearly tender when pierced with a knife.
5. Finish uncovered. Remove the foil, scatter the reserved 1/2 cup Gruyère over the top, and return to the oven for 18–22 minutes until the cheese is deeply golden and bubbling at the edges.
6. Rest before serving. Let the gratin rest for 10 minutes before serving — this allows the cream to set slightly and makes for cleaner portions. Garnish with fresh parsley.
