Leftover Prime Rib Stroganoff

Have you been enjoying our prime rib week?

If you have not been following it, then don’t forget to catch up with our air fryer prime rib and instant pot prime rib roast recipes.

But the best thing about making the prime rib, is the leftovers. A 4 rib (the size we had) was enough for several meals.

Whilst the price on a prime rib can seem like a big investment the quality of the meat is very much worth what you pay for.

But I want extra value for money with my prime rib, or rib roast as you might call it and want as many meals as possible.

That is why I am sharing a leftover prime rib stroganoff with you today. Because not only is it one of the best slow cooker pasta dishes that you will ever try, but because you don’t need a lot of prime rib to make it happen.

This is the amount of leftover prime rib we are using:

But also note, that this beef stroganoff is enough to feed six people, so divide that prime rib between six and you can see how far it truly stretches.

Also note, we also have plenty more prime rib left, to share some more leftover recipes with you this week.

What Can I Do With Tough Roast Beef Leftovers?

Whilst this recipe today, is for using up leftover prime rib, it works with any steak or roast beef leftovers.

This means you can use it, to give a new lease of life to those tough roast beef leftovers. Because cooked in the stroganoff creamy sauce and cooked on slow will make your tough bits tender again.

Beef Stroganoff With Mushrooms

Did you know in a traditional beef stroganoff recipe from years and years ago, there was no mushrooms in a stroganoff.

Beef stroganoff with mushrooms has become a trend that has been followed now for many years.

I find that the mushrooms will bulk up the recipe and create a bigger recipe, but you can make it without mushrooms if you prefer.

Prime Rib Stroganoff In The Slow Cooker

You might be wondering, why am I making a prime rib stroganoff in the slow cooker, well its simple.

You can dump all the ingredients into your slow cooker, you can cook the pasta in the slow cooker, with no need to boil it separately.

Also, because it makes such a large portion, you can have it for lunch then keep the slow cooker on warm and have another helping of prime rib stroganoff for supper.

How To Make Stroganoff Sauce?

If you want to know what makes an easy beef stroganoff, then its all about the stroganoff sauce.

You see the stroganoff sauce ingredients are dumped in the slow cooker with the other ingredients, and as you mix the stroganoff it creates an incredibly creamy stroganoff sauce.

The sauce is made up of a combination of Philadelphia cream cheese, beef stock and milk.

So don’t think you have to slave over a stove to make a creamy sauce as its three amazing, yet simple everyday ingredients.

Leftover Beef Stroganoff Ingredients

leftover beef stroganoff ingredients

Leftovers – We are talking about a leftover beef stroganoff here, so lets talk about the main ingredient and that is leftover roast beef, or what we are using today which is leftover prime rib. No matter what you are using cut it into strips similar to a classic stroganoff.

Pasta – In a classic beef stroganoff you would use a big, long pasta, such as tagliatelle or linguine. But I am all about cutting costs on groceries and going with what you have. That is why I am using some small wholegrain pasta instead. You can use whatever you like.

Mushrooms – A modern day leftover prime rib beef stroganoff would be loaded with mushrooms. I recommend getting the cook times and consistency right, that you use mushrooms and simply slice them in half.

Cream – Instead of using classic cream we are reducing the calories and making a richer creamy sauce with other ingredients. Using Philadelphia, beef stock and milk. If you add milk and cream cheese together it naturally creates a creamy sauce then the beef stock stops the pasta drying out and also adds flavour.

Stock – For our beef stock we used beef stock from a previous instant pot recipe that we had frozen, then cooked the stock from frozen in the instant pot.

Seasoning – For seasoning we used salt, pepper, garlic, mustard, thyme, dill, and parsley.

Then for the kitchen gadgets that we have used in this prime rib beef stroganoff recipe, it has just been our Crockpot. We have this one and it does an amazing job and is also ideal for sauteing too.

Notes

Swap. You can mix and match seasonings and cream cheese flavours. If you don’t like mushrooms, I would recommend swapping for a similar cooking vegetable and one that doesn’t go mushy.
Pasta. Note that as the pasta cooks it soaks up the beef stock, making a very creamy mustard and mushroom sauce.
Thick. If your stroganoff goes too thick, add extra milk, or too thin add extra cream cheese.
