Ingredients

Scale
  • 2 tablespoons olive oil or butter
  • 1 large yellow onion, diced
  • 3 cups diced russet or Yukon gold potatoes
  • 1 1/2 cups cooked corned beef, diced
  • 1 bell pepper, any color, diced
  • 2 cloves garlic, minced
  • 1/2 teaspoon smoked paprika
  • Salt and black pepper to taste
  • Fresh parsley, chopped for garnish
  • 1 tablespoon butter
  • 1 tablespoon all-purpose flour
  • 3/4 cup beef or chicken broth
  • 1/2 cup heavy cream or half-and-half
  • 2 tablespoons whole grain mustard
  • 1 tablespoon Dijon mustard

Instructions

  1. Heat olive oil in a large skillet over medium heat. Add onion and potatoes. Cook for 10-12 minutes, stirring occasionally, until potatoes are tender and golden.
  2. Add bell pepper and corned beef to the skillet. Cook for 5-7 minutes until beef is crispy in spots. Stir in garlic and smoked paprika, cooking for 1 minute. Season with salt and pepper, then transfer hash to a plate.
  3. In the same skillet, melt 1 tablespoon butter over medium heat. Whisk in flour and cook for 1 minute.
  4. Slowly pour in broth while whisking continuously. Simmer for 2-3 minutes until slightly thickened.
  5. Reduce heat to low. Stir in heavy cream, whole grain mustard, and Dijon mustard. Season with salt and pepper. Simmer for 2-3 minutes until sauce coats the back of a spoon.
  6. Return the cooked hash to the skillet with the sauce. Gently fold together until coated. Heat through for 1-2 minutes. Garnish with fresh parsley and serve immediately.

Notes

For a gluten-free version, use a gluten-free flour blend or a cornstarch slurry. For dairy-free, use full-fat coconut milk and olive oil. Do not overcrowd the pan when cooking potatoes to ensure they crisp up. The cream sauce is best made fresh.
