Leftover Pot Roast Nachos

Leftover pot roast just found its new favorite form: crispy, cheesy nachos. Caramelized onions, rich savory gravy, melt-in-your-mouth pot roast, and melty cheese are served over waffle fries for a bite that will having you coming back for more.

Crispy fries loaded with tender beef, melty cheese, and a drizzle of gravy? Count me in!! It’s a cross between nachos and poutine and I am here for it.

Flavor: This recipe was inspired by my French Onion Pot Roast and has all the French Onion flavor you know and love including caramelized onions and a Gruyere cheese blend.
Skill Level: Easy, with one “hands-off” step while onions slowly caramelize.
Budget: Built for leftovers, and flexible with cheeses you already have.

Pot Roast Nacho Ingredients

Leftover Roast Beef: Any leftover beef here will do. Leftover pot roast, roast beef, steak, or prime rib will all work.
Onion: Slice evenly so it caramelizes at the same pace.
Waffle Fries: Swap for french fries, tortilla chips, or my personal favorite, kettle chips.
Cheese: Mozzarella gives you the perfect cheese pull and Gruyere adds a flavor that works perfectly with the leftover pot roast. Shred your own if possible for smoother melting.
Frozen Peas: Toss on straight from frozen. Leave off if you have pea-haters.

More Leftover Pot Roast Ideas

Leftover pot roast is one of those fridge finds that can turn into dinner in minutes.

Tuck it into warm rolls for quick sliders, serve as part of a baked potato bar, or layer it into a grilled cheese with melty cheese and a swipe of horseradish sauce. Stir chopped beef into beef barley soup, fold it into a creamy stroganoff.

It’s also great in tacos, quesadillas, or a simple hash with potatoes and onions, and if you still have extra, freeze portions with a little gravy so the next meal is just a reheat away.
