Creamy Mushroom-Potato Bake

I drove to White Plains on Saturday and held Hannah again — two weeks old now, with the scrunched face of a newborn who is still adjusting to the indignity of existing outside the womb. I held her for an hour while Jennifer showered and David made phone calls and Ethan did homework and Sophie played and Noah napped. An hour of holding a baby. An hour of warmth against my chest, of the small weight, of the breathing, of the smell. Baby smell is a chemical weapon designed by evolution to make grandmothers never put babies down, and it works, and I am its willing target.

Marvin did not come. The trip is too much for him now — the car ride, the new environment, the unfamiliar house (he no longer recognizes David's house, which he has visited a hundred times). I left him with Gloria and I drove to White Plains and I held my granddaughter and I came home and I found Marvin in his chair, watching television, calm, and I told him, "I held the baby today." He said, "That's nice." He said it the way you say "that's nice" about the weather or a television program or any piece of information that is pleasant but not personal. The baby is personal. The baby is his granddaughter. But the connection between the information and the person has been severed, and I said, "Her name is Hannah," and he said, "Hannah is a nice name," and it is, and I agreed, and we ate dinner and I did not cry at the table because crying at the table is not productive and I save my crying for the car, which is the only private space available to a caregiver.

I made a pot roast — a simple, hearty, no-fuss pot roast with carrots and potatoes and onions, braised in broth and red wine until everything falls apart, which is a cooking term and also, this week, a description of my emotional state, though I prefer the cooking version, where falling apart is the desired outcome and indicates tenderness rather than collapse.

The pot roast was already in the oven, falling apart the way I needed it to, and I wanted something alongside it that would feel just as grounding — something soft and rich and layered, something that did not require me to make any more decisions than I already had that day. This creamy mushroom-potato bake has become my answer to those evenings: everything goes into one dish, everything melds together slowly, and what comes out is exactly the kind of tender, unhurried comfort that I needed to set on the table between Marvin and me, without explanation, without ceremony, without tears.

Prep Time: 20 minutes | Cook Time: 55 minutes | Total Time: 1 hour 15 minutes | Servings: 6

Ingredients

2 lbs Yukon Gold potatoes, peeled and sliced 1/4 inch thick
10 oz cremini mushrooms, cleaned and sliced
1 medium yellow onion, thinly sliced
3 cloves garlic, minced
1 cup heavy cream
1/2 cup chicken or vegetable broth
1 cup shredded Gruyère or Swiss cheese, divided
2 tablespoons unsalted butter, cut into small pieces
1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
1/2 teaspoon salt, plus more to taste
1/4 teaspoon black pepper
1 tablespoon olive oil

Instructions

Preheat and prep. Preheat your oven to 375°F. Lightly grease a 9x13-inch baking dish with butter or nonstick spray. Set aside.
Sauté the mushrooms and onion. In a large skillet over medium heat, warm the olive oil. Add the sliced onion and cook until softened, about 4 minutes. Add the mushrooms and garlic and cook, stirring occasionally, until the mushrooms release their liquid and begin to brown, about 6–8 minutes. Season with salt and pepper. Remove from heat.
Mix the cream sauce. In a small bowl or measuring cup, whisk together the heavy cream, broth, and thyme until combined.
Layer the bake. Arrange half the sliced potatoes in an even layer in the prepared baking dish. Spoon half the mushroom mixture over the potatoes and sprinkle with 1/3 cup of the cheese. Repeat with the remaining potatoes and mushroom mixture. Pour the cream mixture evenly over the top. Dot with the butter pieces and sprinkle with the remaining cheese.
Bake covered. Cover the dish tightly with aluminum foil and bake for 35 minutes, until the potatoes begin to soften when pierced with a knife.
Bake uncovered. Remove the foil and continue baking for 18–22 minutes, until the top is golden and bubbling and the potatoes are fully tender.
Rest before serving. Let the bake rest for 10 minutes before serving so the cream sauce thickens slightly and the layers hold together when scooped.
