The Christmas Posts: Delmonico Potato Casserole

One of my co-workers is an excellent cook, and she doesn’t skimp on the butter and cheese.  When I decided to do a rib roast for Christmas dinner, I knew I wanted a calorie-laden, decadent potato recipe to go along with the (pretty basic) roast meat.   She says she’s prepared this several times and that it’s a 5-star recipe.

I believe this comes from Cook’s Country magazine.  The photocopied recipe I have doesn’t say, but I’m pretty sure that’s the source.

Delmonico Potato Casserole

  • 3 Tablespoons unsalted butter
  • 1 onion, chopped fine
  • 2 garlic cloves, minced
  • 2½ cups heavy cream
  • 1½ cups low sodium chicken broth
  • 2½ pounds Yukon Gold potatoes, peeled and cut into ½-inch cubes1
  • ⅛ teaspoon freshly grated nutmeg2
  • Salt and pepper
  • 1 teaspoon grated zest and 2 teaspoons juice from 1 lemon
  • 5 cups frozen shredded hash brown potatoes, thawed and patted dry with paper towels3
  • ¾ cup grated Parmesan cheese
  • ¼ cup finely chopped fresh chives4
  1. Adjust oven rack to upper-middle position and heat oven to 450 degrees.  Melt 1 Tablespoon butter in Dutch Oven over medium-high heat.  Cook onion until softened, about 3 minutes.  Stir in garlic and cook until fragrant, about 30 seconds.  Stir in 2 cups cream, 1 cup broth, Yukon Golds, nutmeg, 2 teaspoons salt, and 1 teaspoon pepper.  Bring to boil, then reduce heat to medium and simmer until potatoes are translucent at edges and mixture is slightly thickened, about 10 minutes.  Off heat, stir in lemon zest and juice.
  2. Transfer potato mixture to 13 x 9 inch baking dish and bake until bubbling around edges and surface is just golden, about 20 minutes.  Meanwhile, melt remaining butter (2 Tablespoons) in large nonstick skillet over medium-high heat.  Cook shredded potatoes until beginning to brown, about 2 minutes.  Add remaining cream (½ cup), remaining broth (½ cup) and ½ teaspoon pepper to skillet and cook, stirring occasionally, until liquid has evaporated, about 3 minutes.  Off heat, stir in ½ cup cheese and 2 Tablespoons chives.
  3. Remove baking dish from oven and top with shredded potato mixture.  Sprinkle with remaining cheese (¼ cup) and continue to bake until top is golden brown, about 20 minutes.  Let cool 15 minutes.  Sprinkle with remaining chives. Serve.

The recipe also states that this can be made ahead through Step 1, cooled completely, transferred to baking dish and refrigerated (covered with plastic wrap) for 1 day.  To serve, proceed as directed in Step 2, increasing baking time to 25 – 30 minutes.

  1. Recipe quote:  We prefer the buttery flavor of Yukon Gold potatoes, but all-purpose and red potatoes also work.  Do not use russets; their high starch content will make the casserole gluey. []
  2. I’m going to wimp out and use it from a jar.  I’m not a big enough nutmeg fan to buy it fresh and grate it myself. []
  3. Recipe quote: We had good results with Ore-Ida Country Style shredded hash brown potatoes, available in the freezer section of most supermarkets. []
  4. I don’t like chives, so I will need to substitute another seasoning to replace them.  Suggestions welcome. []
