Give your leftover pork tenderloin a delicious makeover with a fresh spin on a classic recipe!
This Leftover Pork Tenderloin Stroganoff features the traditional sour cream sauce you know from the beef version, but with a mouthwatering pork twist. Ready in just 20 minutes.

I’m a nut for stroganoff of all kinds. This hamburger version is a hit on Pinterest, my chicken stroganoff fits the bill for chicken lovers, and when I had leftover pork tenderloin in the fridge, I couldn’t resist. The tender meat with a no-canned soup sauce is absolutely perfect.

Simple Ingredients and Substitutions

Recipe Notes
- Leftover Pork Tenderloin – This recipe works best with cooked pork tenderloin that’s been roasted, baked, or grilled. Seasoned or plain both work. Slice it thin and always add it at the end so it stays tender.
- Sour Cream – Adds that classic stroganoff tang and creaminess. Full-fat or light both work.
- Milk or Half and Half -Milk keeps things lighter. Half and half makes the sauce a little richer.
- Onion & Garlic – Nothing fancy here. They build flavor fast and make the sauce taste intentional, not leftover-ish.
- Mushrooms – I use sliced white or baby bella mushrooms. They cook down quickly and give the sauce that classic stroganoff flavor. If your family isn’t big on mushrooms, slice them thin so they blend right into the sauce or omit them all together.

Jill’s Top Tips✨
- If the sauce thickens too much, add a splash of milk or broth to loosen it.
- Slice the pork against the grain for the most tender bites.
- Add the pork last and warm it gently so it doesn’t dry out.
How to make leftover pork tenderloin stroganoff
Step 1: Bring a pot of water to a boil and cook egg noodles according to package directions. Drain and set aside.
Step 2: In a large skillet over medium heat, melt the butter. Add the onion and mushrooms and cook for 5–6 minutes, until the mushrooms release their liquid and begin to soften.
Step 3: Add the garlic and cook for 30 seconds, just until fragrant.
Step 4: Sprinkle the flour over the vegetables and stir constantly for about 1 minute.



Step 5: Add the chicken broth. Bring to a boil, reduce the heat, and let simmer until the sauce thickens.

Step 6: Slowly whisk in milk and simmer over medium heat until the sauce thickens again.
Step 7: Add pork tenderloin, salt, pepper, and garlic powder to the sauce. Reduce heat to low, stirring until the pork is heated through. Next, stir in the sour cream and egg noodles into the pork mixture.



Step 8: Top with fresh parsley and serve immediately.

FAQ
The creamy texture of Greek yogurt makes it a healthy substitute for sour cream. Cream cheese is also another good substitution that will create a creamy stroganoff sauce.
If you don’t have leftover pork tenderloin, either grill or bake your tenderloin. Be sure the pork is cooked to an internal temperature of 145 degrees. You can also substitute cooked chicken in this recipe.
The best stroganoff mushrooms to use are typically cremini or white button mushrooms. These mushrooms have a mild, earthy flavor that pairs well with the rich, creamy stroganoff sauce. They also have a nice texture that holds up well when cooked.
Storage and Reheating
Refrigerator
Store leftovers in an airtight container for up to 3 days.
Reheating
Warm gently on the stovetop or in the microwave. Add a splash of milk or broth to bring the sauce back to life.
Freezing
I don’t recommend freezing this recipe. Cream-based sauces tend to separate once thawed.

Well, you just took me down memory lane. I’m sure we had stroganoff at least once a week when I was growing up. Such a cozy comfort dish for the Fall. And I love that you used leftover pork. What a great and convenient idea. Looking forward to making your recipe. Thanks Jill for sharing.
Thank you Kristy! Yes, I have similar childhood memories, but when I was a kid our stroganoff came out of a box. I have to say this homemade version is so much better. I hope you have a chance to make it soon.
Just wondering where the actual recipe is. I have all the ingredients and I am looking forward to eating it but where are the measurements?
