Equipment

Ingredients

  • 8 oz (225g) uncooked pasta
  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 7 oz (200g) cremini mushrooms sliced (chestnut mushrooms in the UK)
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper
  • 1 clove garlic minced
  • ½ cup heavy cream (double cream in the UK)
  • ½ cup parmesan grated
  • 1 teaspoon cajun seasoning or smoked paprika
  • 1 pound (450g) cooked prime rib sliced into bite size pieces
  • 2 tablespoons chopped fresh parsley chopped

Instructions

  • In a medium-sized saucepan, boil water and salt it. Add your pasta, and cook according to the package instructions until al dente. When the pasta is cooked, reserve 1 cup of the pasta water and drain the pasta.
  • In a skillet over medium heat, melt the butter, and add olive oil. Add the sliced mushrooms, then season with salt, pepper, and cook until tender (about 3-4 minutes).
  • Add garlic, and cook for 30 seconds or until it's fragrant. Add the heavy cream, parmesan, and cajun seasoning.
  • Stir and cook until the parmesan melts then loosen the sauce with reserved pasta water and allow to simmer for a minute. Taste the sauce and see if more salt and pepper are needed.
  • Toss the pasta with the sauce until it's well coated. Add the prime rib to warm it up gently, garnish with freshly chopped parsley and serve.

Notes

  • Don't forget to reserve about a cup of pasta cooking water, it's quite starchy and great for loosening up the sauce. You will most probably need much less than a cup, but to stay on the safe side I always reserve 1 cup and drain the rest.
  • Store in the fridge in a sealed container for up to 3 days.
  • Reheat the pasta in a skillet over low-medium heat, and add a splash of water to loosen the sauce. Do the same if using the microwave. I don’t recommend freezing this creamy pasta.
