Prime Rib Pasta Ingredients
This easy pasta dinner comes together quickly with minimal ingredients! Gather the following ingredients to get your prime rib pasta started!
- Prime Rib – about two pounds of leftover prime rib, cut into bite-size chunks. While slicing your prime rib, trim the excess fatty pieces to use as the gravy base.
- Pasta – my package of Creamette Homestyle penne pasta was just over 8 ounces, or about a half a pound. Use penne, or any other short pasta variety. Farfalle ( bowtie pasta ), cavatappi, large or small shells, fusilli, rotini, or orecchiette pasta are all great options.
- Au Jus & Beef Broth – use up that leftover au jus! It adds amazing flavor. Combine the au jus with beef stock to make 1 1/4 to 1 1/2 cup total liquid.
- Mushrooms – I absolutely love the flavor of cremini ( or baby portabella mushrooms) mushrooms, but white button mushrooms are just as tasty!
- Garlic – fresh, minced garlic is used here but I would easily have added roasted garlic!
Can I Use Other Steak or Leftovers
Most definitely! Any leftover roast, like a pot roast, roast beef, or chuck roast will work wonderfully. Leftover ribeye steak or New York strip is also a wonderful option.
A tender portion of meat is best for this beef pasta, and one that has good fat marbling would be my first choice.

How to Make Prime Rib Pasta
The most important part of this recipe is the prime rib. Depending on how you prepared your prime rib portion, you may have trimmed the rib fat cap off before roasting your prime rib.
Whenever I do this, I season it like the rest of the roast and place it in the roasting pan for adding to the amazing drippings! This roasted fat cap or the fat trimmed off your cooked roast is a great start to the mushroom garlic gravy.
Make the Garlic Mushroom Gravy
- Start your pasta while you make the gravy. Cook the penne pasta according to the package instructions. Drain and rinse in cool water, then set aside.
- Render the fatty pieces of your prime rib in a large skillet or non-stick frying pan. Cook until the fat is softened and you have a good amount of oil in your skillet. Add the leftover au jus and beef broth ( a bit of Better than Bouillon will also add more hearty beef flavor ).
- Saute the sliced cremini mushrooms and minced garlic in the beef sauce until the mushrooms are tender, about 5 minutes.
- Stir the sliced prime rib meat into the mushroom gravy and cook for 5 – 10 minutes, or until the meat is warm.
- Remove from heat and serve immediately over the cooked penne pasta. Garnish with freshly ground coarse black pepper and chopped parsley.

- 1 cup beef broth
