Can I use a different cut of beef?

Absolutely. Ribeye is classic and super tender, but sirloin works great. You can also use flank steak—just slice it thin against the grain so it stays tender.

What if I don’t like super spicy food?

Use a milder kimchi if you can find it, or rinse your kimchi lightly and pat it dry (it reduces heat and tang). You’ll still get that signature flavor without the full spice punch.

Can I make this ahead of time?

You can cook the bulgogi-kimchi mixture ahead and store it in the fridge. When you’re ready, reheat in a skillet and assemble fresh so the rolls don’t get soggy.

How do I store leftovers?

Keep the filling in an airtight container in the fridge for up to 3 days . Reheat in a skillet for best texture. (Microwave works too—just expect it to be a little softer.)

What cheese works best besides provolone or American?

Mozzarella melts nicely, and pepper jack adds extra kick. Even cheddar works—just know it’s a different vibe (still delicious).

Instructions

Thinly slice the beef, onion, and bell peppers.
In a bowl, mix soy sauce, sesame oil, garlic (if using), and sugar (if using). Add beef and marinate for at least 15 minutes.
Heat vegetable oil in a skillet over medium-high heat.
Add onions and bell peppers and sauté until tender, about 5 minutes.
Push veggies aside and add the marinated beef. Cook until browned, about 5 minutes, stirring occasionally.
Stir in the chopped kimchi and cook for 2 more minutes.
Spoon the mixture onto toasted hoagie rolls, top with cheese, and broil for about 2 minutes until melted.
Serve hot and enjoy immediately.

Notes

Slice the beef as thin as possible for the most tender bite.

Provolone melts smoothly; American cheese gives a classic cheesesteak feel.

For extra heat, add a splash of kimchi juice to the skillet.

Best enjoyed fresh, but leftovers reheat well in a skillet.
