⭐ Family Foodie 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.
- 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!
🔥 How to Reheat Creamy Pasta
Leftover prime rib pasta can be reheated easily in the microwave or in a skillet on the stove.
If you choose to reheat on the stove, just add a bit of olive oil or butter to the skillet and stir continuously while reheating to avoid burning.
That way, you will create a nice crust on the pasta, which is quite tasty by itself!
