Let's get started! Here's what you'll need:

Ingredients on a kitchen counter: shredded cheese, leftover roast cooked with onions, and flour tortillas.
My roast was cooked with onions so they're in the container- this is the easiest way to include them. I also forgot to include the nonstick cooking spray in this photo, oops!

Ingredients:

Leftover pot roast- the star of the show, any pot roast recipe should be fine from your grandma's chuck roast recipe to the crock pot favorite Mississippi pot roast.

Quesadilla cheese- A type of shredded cheese that melts easily and is commonly used in quesadillas, with a mild and creamy flavor. You could also use a taco blend, monterey jack, whatever your family likes.

Onions- the easiest option here is if you have onions that cooked with your roast, that’s perfect. Otherwise you can saute some up or caramelize them low and slow- my friend Susan does it in her slow cooker and then freezes them in portions for meals like this.

Flour tortillas- you can use corn if you prefer, but my family enjoys the flour ones. You could also opt for uncooked tortillas since we’re frying them up.

Oil or butter- To get that crispy golden brown exterior on a quesadilla we need some fat in the pan. It can be just a little bit with a nonstick cooking spray, or you can pour in some olive oil or use butter.

Equipment:

You’ll need a large skillet or nonstick pan- I like my cast iron- and a spatula. You will also want a fork to shred your pot roast, and if your roast didn’t have onions a knife and cutting board for those.

How to Make Leftover Roast Beef Quesadillas:

Step 1: Preparation

Shred beef and cut onions. Cooking goes very quickly so we need to make sure all our ingredients are ready to go so we don’t burn our dinner. I recommend portioning out the meat into small piles, one for each quesadilla.

Step 2: Saute onions if needed

Ideally you’ll have some that are already cooked (caramelized onions freeze well) either ahead of time or along with your pot roast, but if not you can give them a quick saute over medium heat to your preferred doneness. Feel free to add anything else you like as well- if you're already sauteeing, bell peppers or mushrooms are great additions.

Step 3: Assemble and cook

Spray your skillet with oil or coat it with some melted butter, then add your tortilla and sprinkle cheese on one half of the tortilla. Add your shredded beef and onions, then top with another bit of cheese so that cheese will stick to the other side of the tortilla.

Fold over the quesadilla and press it down, and after about 10 seconds flip the quesadilla.  Cook another 30 seconds or so on the other side to get the tortilla crisp and the cheese melted.

Remove the quesadilla from the pan and then repeat this step to make all your quesadillas.

Note: If your tortillas are burning, turn the burner down to low. They can go from perfectly crisp to burned very quickly on higher heat.

Toppings

Like these pulled pork tacos, the topping options are plentiful. Some favorites include:

  • Sour cream
  • Avocado
  • Guacamole
  • Pico de gallo
  • Adobo sauce
  • Salsa verde
  • Diced tomatoes
  • Cilantro
  • Lime wedges

FAQ

Can I use another kind of meat?

Of course, these can easily be steak quesadillas if you have leftover steak or leftover prime rib instead. Just make sure whatever cut you use is already cooked beef- these don't cook long enough to use raw meat. If you don't have much meat leftover or are trying to stretch what you have, you can also supplement it with black beans.

Do I need any other seasoning?

It's not necessary since starting with leftovers means our meat is already seasoned from the first time it was cooked. That said, if you want to spice yours up with some extra flavor you can absolutely do that. Some ideas for you are: green chilies, chili powder, taco seasoning, steak seasoning, garlic powder, black pepper, or red pepper flakes.

Can I use two tortillas for one quesadilla?

Absolutely! I like the method of folding the quesadilla because there is less area for the toppings to escape out of when flipping, but you can instead cover the entire tortilla and add a second tortilla instead of folding over the empty half. Just be careful flipping!

Got rotisserie? This pesto pasta is a great way to use it. During winter a family favorite here is this chicken potato chowder.

I hope you love these tasty quesadillas! If you do be sure to come back and rate it.

    Thank you for the great idea. Seems so simple but it never crossed my mind to use leftover pot roast, easy to customize as well.

    Wonderful. Never thought of roast beef quesadillas. A great alternative to barbeque... especially when you have tortillas and no buns.
