Pot Roast Potato Cakes with Poached Eggs, Fresh Greens, and Horseradish-Mustard Vinaigrette

This hearty dish, which is a great way to reinvigorate leftover Foster Family’s Pot Roast with Herb-Roasted Vegetables, is inspired by Southern dishes featuring “low” cuts of meat. With savory layers of potato, roast, and poached eggs finished with the cool heat of the Horseradish-Mustard Vinaigrette and brightened with fresh greens, this crowd-pleaser makes for a decadent Sunday brunch, but it can just as comfortably double as the main event at dinner. Serve with warm, crusty toast for a complete meal.



4 to 5 Yukon Gold potatoes (about 1 pound), peeled and halved

2 cups cooked, shredded pot roast

3 tablespoons minced onion

1 large egg

2 tablespoons all-purpose flour

1 tablespoon chopped fresh parsley

Sea salt and freshly ground black pepper

1 tablespoon olive oil

1 tablespoon unsalted butter


2 teaspoons distilled white vinegar

Pinch of sea salt

1 or 2 large eggs per person


4 cups baby spinach or arugula, washed and drained

Horseradish-Mustard Vinaigrette (recipe follows)

2 tablespoons chopped chives

1. Preheat the oven to 200°F.

2. Place the potatoes in a large pot with enough water to cover by about 1 inch and bring to a boil. Reduce the heat to a simmer, cover, and cook until the potatoes are tender, 20 to 30 minutes. Drain and mash roughly with a potato masher; the potatoes do not have to be smooth.

3. Combine the potatoes, 1 cup of the pot roast, the onion, egg, flour, and parsley in a large bowl and stir to thoroughly combine. Season with salt and pepper to taste and stir to mix. Form into four 3-inch-round, ½-inch-thick patties and refrigerate for about 15 minutes.

4. Heat the olive oil and butter in a large nonstick or cast-iron skillet over medium heat until hot. Add the cakes and cook for about 3 minutes per side, until golden brown and crispy. Place in the oven to keep warm.

5. Fill another large skillet with water about 2 inches deep and bring to a boil. Add the vinegar and salt and reduce the heat to a simmer.

6. Add the eggs one at a time and poach for 2 to 3 minutes, until the whites set and a thin, translucent film forms over the yolks. Use a slotted spoon to gently transfer the eggs to a paper towel–lined platter to drain.

7. Just before serving, toss the greens with ¼ cup of the vinaigrette.

ASSEMBLY | Place 1 potato cake on each plate and top with 1 or 2 poached eggs and about 1⁄4 cup of the remaining pot roast. Drizzle about 1⁄4 cup of the remaining dressing on and around the eggs and top with a handful of the dressed greens. Season with salt and pepper to taste and serve warm, garnished with the chives.
