Leftover Pot Roast Patty Melts

This post may contain affiliate links. See my full disclosure for further details.

I don’t know about you, but when I make a roast, I almost always have leftovers. Well, these Leftover Pot Roast Patty Melts are the best thing to happen to leftover roast since….EVER!

In fact, I purposely cook extra roast now, just to make sure I have enough leftovers to make these sandwiches the next day.

With a creamy mayo-steak sauce spread, grilled onions, and two kinds of cheese, these sandwiches are the best variation on a patty melt I’ve ever tried.

And they were a huge hit with my husband and three boys!

You can grill these on a stove-top or electric griddle, or in a panini press or George Foreman style grill.

No matter how you cook them up, you’re going to love these leftovers!

Leftover Pot Roast Patty Melts

With a creamy mayo-steak sauce spread, grilled onions, and two kinds of cheese, these sandwiches are the best variation on a patty melt I've ever tried.


    For the sandwiches

    • 2-3 cups leftover shredded pot roast
    • 8 slices sturdy bread
    • 3 tablespoons butter, plus more for the bread
    • 2 medium onions, thinly sliced
    • Salt and pepper to taste
    • 4 slices Provolone cheese
    • 4 slices cheddar cheese

    For the sauce

    • 1/2 cup mayonnaise
    • 3 tablespoons steak sauce
    • 1/8 teaspoon pepper


    1. Re-heat the pot roast in the microwave. Butter one side of all 8 slices of bread.
    2. Melt 3 tablespoons of butter in a large skillet. Add onions and cook over medium heat, stirring frequently, until onions are soft and golden brown.
    3. Season with salt and pepper and remove from heat.
    4. Combine the sauce ingredients in a medium bowl.
    5. Heat a griddle over medium-high heat. Spread a layer of the sauce on the unbuttered side of 4 slices of bread. Top with a piece of cheddar cheese.
    6. Top each slice of cheddar with about 1/2 cup of pot roast, a generous portion of onions, and the slice of Provolone cheese. Top with the remaining slice of bread, buttered side out.
    7. Grill, flipping once, until both sides are browned and crispy.
    8. Serve patty melts with the remaining sauce, for dipping.
