How to Make Spicy Nachos with Steak
To make these cheesesteak nachos spicy, try adding a diced jalapeño pepper or a few shakes of hot sauce to the cheese sauce. Top the nachos with more diced jalapeños!
Because these nachos are a hybrid, it’s best to use a mix of cheeses. Classic cheddar helps create the nacho cheese sauce, while provolone adds the Philly cheesesteak flavor!
I like sirloin because it’s lean, tender, and juicy! You could also use flank steak or skirt steak. Flank is leaner than sirloin, while skirt is fattier.
You can make them on the day you plan to serve them and reheat them gently in the oven. However, these nachos are best eaten fresh from the oven. They don’t keep well as the tortilla chips start to get soggy.
It is important to slowly add the cheese to the milk on low heat to prevent the sauce from becoming grainy. If the cheese isn’t melting into the sauce, return it to low heat and stir constantly while it melts.
I don’t recommend freezing nachos, as the chips become soggy and the sauce can separate once thawed. Make only as much as you can eat in one sitting for the best results.
What to Serve with Steak Nachos
Philly Cheesesteak Nachos are the perfect food to serve for parties, family gatherings, football food, and more! They go great with other appetizers, like jalapeño poppers and enchilada cups. And they go well with your favorite party dips too, like this classic taco dip! If you need a cocktail for the crowd, serve these pitcher margaritas.

Becky’s Tips
- If possible, avoid pre-shredded cheese, as it doesn’t melt well.
- You could use flank steak or skirt steak in place of the sirloin.
- Make vegetarian by omitting the steak!
- Stir the cheese into the sauce slowly over low heat to avoid a grainy sauce.
- Philly cheesesteak nachos are best enjoyed on the day they are made.
