Description

A rich, creamy Alfredo pasta tossed with tender slices of prime rib, perfect for a cozy dinner or special occasion. This dish combines indulgent flavors with simple preparation, creating a meal that’s both comforting and elegant.


Ingredients

Scale
  • 12 oz fettuccine or preferred pasta

  • 1 to 1.5 cups cooked prime rib, thinly sliced or shredded

  • 2 tablespoons unsalted butter

  • 3 cloves garlic, minced

  • 1 cup heavy cream

  • 1 cup whole milk

  • 1 cup freshly grated Parmesan cheese

  • ½ teaspoon salt

  • ¼ teaspoon freshly ground black pepper

  • ¼ teaspoon nutmeg (optional)

  • 2 tablespoons chopped fresh parsley, for garnish

  • 1 tablespoon olive oil (optional, for searing beef)


Instructions

  • Bring a large pot of salted water to a boil and cook the fettuccine according to package instructions until al dente. Drain and set aside, reserving ½ cup pasta water.

  • Slice the prime rib thinly against the grain. Heat olive oil in a skillet over medium heat and sear beef 1–2 minutes to warm, then remove and set aside.

  • Melt butter in the same skillet over medium heat. Add garlic and sauté for 1–2 minutes until fragrant.

  • Pour in heavy cream and milk, stirring constantly. Let simmer for 3–4 minutes, then reduce heat to low.

  • Gradually whisk in Parmesan cheese until the sauce is smooth and creamy. Season with salt, pepper, and nutmeg if using.

  • Add cooked fettuccine to the sauce and toss gently to coat. Use reserved pasta water to adjust consistency if needed.

  • Fold in the sliced prime rib, heating for 1–2 minutes until warmed through.

  • Garnish with chopped parsley and serve immediately with extra Parmesan if desired.

Notes

  • Use thinly sliced prime rib for tender bites.

  • Heavy cream ensures a rich, creamy sauce.

  • Reserve pasta water to adjust sauce consistency.

  • Optional add-ins: sautéed mushrooms, spinach, or sun-dried tomatoes for extra flavor.

  • Leftover prime rib works perfectly and adds convenience.
