I love making my Oven-Baked Corned Beef And Cabbage, but I always manage to make too much. After a few corned beef sandwiches and still having leftover meat, I needed another recipe to finish off those delicious leftovers. What’s better than a warm, gooey quesadilla? Nothing! Especially when served with a creamy horseradish crema. Your family will love it.

What Ingredients Are Needed?

  • Flour tortillas – I like using the burrito-sized. Fajita size also works.
  • Leftover corned beef – try our recipe for baked corned beef.
  • Butter – used to saute the cabbage. If using leftover cabbage, cope it fine and skip the butter.
  • Leftover mashed potatoes – you can make your own or use store-bought. Try our Roasted Garlic Horseradish Mashed Potatoes for a flavor explosion.
  • Swiss cheese – I like using sliced but shredded works as well. You can use any cheese you like or have on hand.
  • Sour cream
  • Mayonnaise
  • Prepared horseradish – don’t get horseradish sauce. Look for prepared horseradish by the deli or dairy sections.

  11. Cook the other side until golden on the bottom.
  12. Remove and slice into quarters. Repeat with the remaining ingredients.

Ingredients

Scale

2 tablespoons butter, plus more to grease your skillet

1 (10-ounce) bag angel hair cabbage or leftover cooked cabbage

8 flour burrito-size tortillas

2 cups leftover mashed potatoes or a container of ready-made refrigerated mashed potatoes

½ pound leftover corned beef, chopped

48 slices Swiss cheese

For the crema:

½ cup sour cream

½ cup mayonnaise

24 tablespoons prepared horseradish

Instructions

For the quesadillas:

Melt the butter in a large, non-stick skillet over medium heat and then add the cabbage.

Toss the cabbage with the butter and cook until soft and lightly caramelized. 

Spoon the cabbage into a bowl and set aside.

In the same skillet, brush the bottom lightly with melted butter.

Add one tortilla to the skillet.

Top with 1-2 slices of the Swiss cheese.

Spread ½ cup of the mashed potatoes over the tortilla and cheese.

Top with ¼ of the corned beef and ¼ of the cooked cabbage.

Add another 1-2 slices of Swiss cheese and top with another tortilla.

Cook until the bottom is golden brown.

With a spatula, carefully flip the tortilla and cook until the other side is golden on the bottom – about 3-4 minutes per side.

Repeat with the remaining ingredients.

For the crema:

Whisk together the sour cream, mayonnaise, and prepared horseradish in a medium bowl.

Slice each tortilla into fourths and serve with crema on the side.
