Equipment

  1. In a large skillet or Dutch oven, melt the 2 tablespoons of unsalted butter over medium heat. Add the thinly sliced yellow onion and cook, stirring occasionally, until softened and translucent, about 5-7 minutes.

  2. Add the sliced cremini mushrooms to the skillet with the onions. Cook, stirring, until the mushrooms have released their moisture and are nicely browned, about 7-10 minutes. Stir in the minced garlic and cook for an additional minute until fragrant, being careful not to burn it.

  3. Sprinkle the 1/4 cup of all-purpose flour over the onion and mushroom mixture. Stir well to coat everything evenly and cook for 1 minute, allowing the flour to toast lightly. Gradually whisk in the 2 cups of beef broth, scraping up any browned bits from the bottom of the skillet. Bring the mixture to a simmer, stirring constantly, until the sauce begins to thicken.

  4. Stir in the thinly sliced or diced cooked prime rib, 1 tablespoon of Worcestershire sauce, and 1 teaspoon of Dijon mustard. Continue to simmer, stirring occasionally, until the prime rib is heated through and the sauce is luxuriously thick, about 5-7 minutes.

  5. Remove the skillet from the heat and stir in the 1 cup of room-temperature sour cream. Stir gently until the sour cream is fully incorporated and the sauce is smooth and creamy. Important: Do not boil the stroganoff after adding the sour cream, as this can cause it to curdle.

Notes

Refrigerated leftovers should remain fresh for 3-4 days. Reheat gently over low heat, stirring frequently. Avoid boiling to prevent curdling. You can add a tablespoon or two of beef broth or milk to thin the sauce if needed. Can be frozen for 2-3 months; thaw overnight in the refrigerator before reheating.
