What to Do with Leftover Prime Rib or Steak
In my house, we look forward to a prime rib at least once a year over the holidays. There is nothing I love more than juicy roast beef and a little au jus to dip it in.
But of course, what to do with prime rib leftovers? I like making hot roast beef sandwiches with remoulade sauce, or heating it up with a side of mashed potatoes, but one of my favorite leftover recipes of all time has got to be this Creamy Penne Pasta.
Best Prime Rib Leftover Recipe
It’s just like Applebee’s creamy penne pasta with sliced prime rib, but even better! Honestly, it’s so delicious, I make it year-round using leftover steak. It’s one of my favorite steak pasta recipes.
I know you’re going to love it. My family always asks me to make this dish when we have leftover steak or roast beef, and I’m happy to make it. It’s just so easy!
This was amazing!!! My family agrees that this recipe was even better than having the Prime Rib the first time around. My teenage son said it was one of his favorite top meals ever!!! Thank you very much! ❤️

How to Make Leftover Prime Rib Penne Pasta
- Heat olive oil in a skillet. Add onion (chopped) and sauté until translucent.
- Add garlic (minced) and cook for about one more minute.
- Then, add ⅔ lb. sliced cremini mushrooms and the butter and cook until tender, about 5-6 minutes. Stir continuously to avoid burning.
- Pour in heavy cream and lower the heat. Let simmer for about 5 minutes until the liquid is reduced.
- Add chopped sun-dried tomatoes, salt, pepper, and parsley to taste. Stir and remove from heat.
- Slice the prime rib or rib eye steak into thin slices.
- Cook penne pasta in a large pot with boiling water and salt.
- Remove from heat about 2 minutes before the time indicated on the packaging so it is just slightly underdone (al dente). Drain the pasta in a colander.
- Add the penne to the skillet with the sauce and stir. Then add the sliced prime rib. Return to heat and stir for about 1 minute in order to incorporate all the flavors.
- Serve immediately with parmesan cheese, more fresh parsley and freshly ground black pepper to taste. Enjoy!

Tightly wrapped with saran wrap and stored in a plastic container in the refrigerator it will last 5 days.
I make this dish using a decadent sun-dried tomato and mushroom cream sauce. It is an amazing combination of flavors that is perfect for this rib roast or leftover steak! You can also try my Creamy Lemon Butter Sauce Recipe to mix things up. It is so delicious!
Leftover Prime Rib Pasta Tips
- For a real Italian experience, cook the pasta in boiling salted water and leave it a bit “al dente”, as it will cook additionally in the skillet. Once it is cooked, drain it immediately and add it to the sauce.
- Don’t let the pasta sit in the colander, or it might stick together, and will continue cooking in its own heat.
Substitutions
- Heavy cream can be substituted with half and half if you prefer your leftover prime rib pasta lighter.
- Grated Parmesan is optional for this recipe as the sauce is already creamy and buttery enough, but you can add it for extra richness!
- You can also use mixed mushrooms if you prefer.
- Leftover steak works perfectly in this recipe, too!
- Add Crispy Air Fryer Bacon for an even richer pasta!
- You can even use Leftover Ham
How to Reheat Prime Rib Pasta
You can reheat this dish easily in a skillet on the stove.
Just add a bit of olive oil or butter to the skillet and stir continuously while reheating for approximately 10 minutes. It reheats really nicely.

This is wonderful! Never before have I enjoyed my leftover rib roast. I was feeding five so I used the recipe for six and did not have a single scrap left. Since of us are big sun-dried tomato fans we did use a little less that the recipe asked for and did a fine chop. I actually think this made it better because instead of getting a big bite of tomato, you simply got this nice pop of flavor in almost every fork full. My daughter took the recipe home with her to use on her leftover tenderloin.
Thanks so much for sharing this with me, Sandi! This recipe is always a favorite at our house too. I am so happy your family enjoyed it.
Oh my! This is so very good! No onions or mushrooms for me (not a fan). And I only had cavatappi no. 87 pasta (no clue) on hand. This pasta was awesome. Next time, I’ll use it again.
Jane, we’re so glad you enjoyed it! Thank you for leaving us a comment! Cavatappi is delicious. What a great choice!
Just cooked it to use some of the steak leftovers we had. Great, this recipe is a keeper!!!
That is so awesome – we are so glad you enjoyed it! Thank you!
Made this with my leftover Prime Rib from New Years Day and was delicious. Will definitely be making again with Rib Eye Steak. Wish I could post a picture because it came out just like yours. Thank you for the new meal planner idea
That is awesome, Mary! Thank you so much for sharing and we would love to see a picture! Feel free to email it to us!
Any ideas for a substitution for the sun dried tomatoes? I’d like to make this tonight and that’s the only ingredient I don’t have. Was considering adding a bit of red pepper, finely chopped, to add color/flavor?
Hi Karen! Thank you so much for your question. You can use grape tomatoes and saute them in a little bit of olive oil or you can omit the sundried tomatoes all together. A bit of red pepper sounds yummy! We hope you love it!
If I had just saved pasta water to thin the sauce out with at the end, this would have been perfect and added just the right amount of salt.
Hi Emily! We hope you enjoyed it regardless – it sounds like it was still good! Thank you very much!
I made this with leftover prime rib from New Years Day and it was absolutely fantastically delicious! My husband said make sure you save this recipe so you can make it again. I followed the recipe except, I used pappardelle pasta and I added about a 1/4 cup of white wine. Thank you for sharing a wonderful recipe that I will make over and over again.
Patty, that is awesome! Thank you so much! We’re so glad you and your husband enjoyed it, and those edits sound delicious.
I made this for lunch with leftover Tbone steak and since all of my family preference is medium rare and lower, I didn’t have any fresh mushrooms. It tasted good 👍 😋 I’ve added it my favorite recipes list. I will have to try this with leftover prime rib since I always make a larger one than necessary since I never know who will be showing up 😊
That is so awesome, Julie! It’s so delicious with steak. Thank you for sharing!
