It's true, steak (beef) can be one of the most expensive meats at the grocery store. When we use a tasty meat like this, we want to enjoy it in as many meals as possible! So we get creative! A steak quesadilla is a great way to turn it into a full meal that will feed a crew, little or big. They're quick and easy to put together, so they're perfect for those busy weeknight meals! Even the kids can help toss them together in a pinch.

Yep, you read that right. One of our favorite and easiest ways to make a fajita steak quesadilla is from leftovers. Specifically, the leftovers from our fajita steak rice bowls! How is it that the steak, peppers, and onions manage to taste better after they've been sitting in the fridge for a day or two?! It's some kinda magic, for sure.

Grab your leftovers, LOTS of cheese, some tortillas, and a little bit of cooking oil and you're ready to get cooking! Chances are, you've got all of those ingredients in your kitchen, which makes this the perfect shelf cooking recipe. Score!

Feel free to toss the leftover beans and rice into your quesadillas as well. (Although you don't have to if you don't have any left.) They'll really help to stretch the filling if you're running low and they'll help to fill those bellies, too! Mash the beans onto the tortilla to help to keep them from falling out. Plenty of cheese will help the rice to stay in and keep it from falling out when you're eating it. You can never have to much cheese, right??

See what we mean? The combinations are endless here since you can use whatever you've got! We've even added a few banana peppers in the past to add a little tangy flavor.

If you have leftover rice and beans and don't feel like adding that to the quesadilla, they always make a good side. We usually pair a salad and our favorite homemade vinaigrette dressing as a nice healthy option, too.

Much like with the steak rice bowls, you really can't go wrong dipping these in sour cream and salsa. You can even serve your leftover guac with them! Want to know how to keep your guac from going brown in the fridge?

Take whatever leftover guacamole you have and put it into an airtight container. Then, pack it down with a spoon to get all of the air bubbles out. Cover with a half inch of water, put the lid on and store in the fridge for up to 3 days. Pour the water off the top and stir before serving.

Yes, we know… It sounds crazy! But it's really the only way to keep air from touching the guacamole and turning it brown. The guac is dense enough that the water won't seep into it and will just sit on top, as long as you pack it down well. You're welcome for that random and super helpful #TipOfTheDay. 😉


This really is the easiest recipe, ever! If you don't have any leftovers to work with, that's okay. Head on over to this post to get tips on 5 different ways to cook your steak, along with a great recipe on making steak fajitas, bell peppers and onions. Now, on to the recipe!

Did you know you can freeze quesadillas? Make them as normal, then allow to cool. Cut if you'd like, then wrap really well in foil and store in a freezer bag. Thaw overnight in the fridge, then reheat in the foil in the oven at 350° for 10-15 minutes or until heated through.
