Prime Rib Pasta (Prime Rib Leftover Recipe) - Little Sunny Kitchen (2024)

Turn your roast beef leftovers into delicious flavorful pasta! This Creamy Prime Rib Pasta is so simple, and comes together in just 20 minutes!

Roasting a Prime Rib at the holidays is a treat, and we rarely have any leftovers. But if we do, I always make sure that nothing goes to waste. I repurpose the meat and make delicious Prime Rib Sandwiches or this creamy pasta. Both recipes are super quick and easy to make, and you are going to love them!

This pasta is made with leftover prime rib meat that is cut into bite-sized pieces, perfectly cooked pasta, mushrooms, and an easy and flavorful parmesan cream sauce. If you’re a fan of creamy pasta, you should also check out my Creamy Shrimp Pasta, and this luxurious Salmon Pasta dish.

Key Ingredients

Here’s what you need to make this easy pasta dish:

Complete list of ingredients and amounts can be found in the recipe card below.

• Prime Rib:You saved someprime rib roastfrom last night and stored it in the fridge. Take it out of the fridge, and cut it into bite-size pieces removing any large pieces of fat.
• Pasta: You can use any short pasta in this recipe – I used penne. I like to use a ridged pasta shape so that the pasta will hold onto all of the delicious cajun cream sauce.
• Mushrooms: I’m using cremini mushrooms (these are called chestnut mushrooms in the UK) that I sliced and sauteed before making the sauce. You can also use button mushrooms here.
• Cajun: Pick this seasoning up from your local grocery store. Cajun seasoning is generally a blend of salt, pepper, chili powder, garlic, and other spices. It’s a bit smoky, a bit spicy, and a delicious all-purpose seasoning to cook with. Look for“Slap Ya Mama”cajun seasoning at your local store or online, or I’ve had great results withMcCormick seasoning.
• Parmesan Cheese: Grate parmesan fresh from a block or wedge. It tastessomuch better and melts easier in the cream sauce.

How To Make Prime Rib Pasta

1. In a skillet over medium heat, melt the butter, and add olive oil. Add the sliced mushrooms, then season with salt, ground black pepper, and cook until tender (about 3-4 minutes).
2. Add garlic, and cook for 30 seconds or until it’s fragrant. Add the heavy cream, parmesan, and cajun seasoning.
3. 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.
4. 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.

Recipe Tips

• Use any Leftover Roast Beef: I made this pasta using prime rib leftovers, but any roast beef leftovers work here.
• Prime rib is much easier to slice when it’s cold, so be sure to slice it after you take it out of the fridge.
• Reserve some of the pasta waterbefore you drain the pasta! In case your sauce seems too thick, starchy pasta water is the perfect thing to adjust the consistency of the sauce if you have to.

Storing Tips

Store leftovers in an airtight container in the refrigerator forup to 3 days. Reheat gently in a pan with a splash of water, or reheat in the microwave.
