Green Bean Casserole Nugget Markets signature recipes

Up the ante on this family favorite with fresh green beans, crispy fried shallots and a flavorful, homemade mushroom sauce.

Ingredients

  • 3 cups plus 2 tablespoons vegetable oil, divided
  • 4 large shallots, sliced thin on a mandoline
  • 1½ cups water
  • ½ ounce dried porcini mushrooms
  • 1½ pounds fresh green beans, trimmed and halved
  • ¾ pound white button mushrooms, trimmed and cut into ½-inch slices
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • ¼ cup unsalted butter
  • ¼ cup all-purpose flour
  • 1 cup milk
  • ½ cup heavy cream
  • ¼ teaspoon ground nutmeg
  • Kosher salt, to taste
  • Cracked black pepper, to taste

Preparation

Heat 3 cups oil over medium-low heat in a medium saucepan to 275°F. Add shallots and cook gently, stirring occasionally until golden brown. Use a slotted spoon to remove shallots from oil and transfer to a sheet pan. Blot with paper towels and sprinkle lightly with salt.

In a small pot, bring 1½ cups water to a boil then remove from heat, add dried porcini mushrooms and allow to steep 30 minutes to create a mushroom broth.

To prepare green beans, cook in a large pot of salted boiling water for 6–8 minutes. Drain and shock in ice water, then pat dry.

In a sauté pan over medium-high heat, add enough oil to coat pan. When oil is smoking, add fresh mushrooms in a single layer and sprinkle with salt (cook in batches if needed). Allow mushrooms to brown without moving them for 1–2 minutes before flipping. Once mushrooms are cooked, remove from pan and set aside.

In the same pan, add oil to coat, then sauté onion and garlic until translucent, remove from pan and set aside.

Add butter to that same pan. When melted, add flour and cook for 2 minutes. Whisking constantly, gradually add 1½ cups mushroom broth and milk, scraping off all the browned bits from the bottom of the pan. Allow to thicken, then add cream, nutmeg and sautéed mushrooms and onions. Season with salt and pepper.

Preheat oven to 350°F.

Add green beans to the mushroom sauce and toss to coat. Mix in ⅓ of the fried shallots. Transfer mixture to a casserole dish and bake until bubbling around the edges, 20–30 minutes. Serve topped with remaining fried shallots.

If preparing shallots ahead of time, store in an airtight container at room temperature with a layer of paper towels underneath. Store pre-blanched green beans in a zip-top plastic bag in the refrigerator.
