Leftover Steak Quesadillas
These Leftover Steak Quesadillas are by far my favorite way to use leftover steak. Ooey cheese in a warm tortilla with onions and mushrooms. YUMM!

Steaks are an ultimate treat at our house , my three sons and husband are major carnivores . When they know we are grilling thick cuts of beef they will skip all other meals that day to make sure they can finish every little morsel. My husband , for the fear we won’t have enough meat ALWAYS grills at least two to three extra steaks . With my husbands phobia of not having enough meat we always have at least one whole steak leftover ,if not more. Over the years I have come up with many creative ways to use the leftover meat but these Leftover Steak Quesadillas are by far my favorite way. I have also done this with our left over holiday prime rib and they are even more fabulous. You could always make a soup like my leftover Prime Rib Soup .

- Leftover Steak or Prime Rib

Notes
Leftover prime rib is a good substitute for the steak but honestly any leftover meat will work
I highly recommend grating your own cheese. It melts better but in a bind you can use already shredded .
Yes , any cheese will work. Use your favorite or what you have on hand
Yes ..Bell peppers or diced jalapenos both would be a great addition
Great recipe…………….thanks for sharing……………….

So, essentially, you have used two different skillets for a Quesadilla?
Yes
Dumbest thing i ever heard! Cook it in one skillet LIKE EVERYONE ELSE! LMAO
Hey Better cook , please direct me to your website where your stellar recipes are located. In the mean time I will admit this recipe needs a little updating since I posted this early in my blogging career. New photos and instructional video would help with any confusion. I am still confused about your comment though. How do you make quesadillas in one pan? In one skillet there is the filling (onions, mushrooms, steak etc) Then the other skillet is to make the actual quesadilla. Very simple recipe that has gotten a ton of good reviews on other platforms like Pinterest . Again feel free to link your website in the comments . Thanks Debbie
There’s no reason to be snarky. If you don’t like it, scroll on past instead of being rude.
What a great recipe with so much flavor! I love the mix of the veggies with the steak and cheese! Definitely use the wine for deglazing!
Great recipe! We leave mushrooms out as they don’t really appeal to us. I simply move the steak mixture to a bowl, wipe out skillet with a paper towel and move on with the tortilla in the same skillet. I have made this several times with leftover steak; today I am using fresh steak. Quick and easy! Thank you for this delicious recipe!😊
I am so glad you like this recipe . We are grilling steaks for my twins birthday , hoping for leftovers lol.
