Philly Cheese Steak Sandwiches with Garlic Aoli

I love a great steak on the grill. But my true love for steak comes in the form of a sandwich!

Steak sandwiches are a great way to use the more economical cuts of steak like a round, flat-iron, and flank steaks, which can be tougher when grilled as they are leaner and more muscle-y.

Philly cheese steak sandwiches combine a few of my favorite foods … sauteed onions & peppers, flavourful steak, crusty bread, and cheese!

These sandwiches are an easy weeknight meal for a family. We leave all the toppings separate to let our kids build their own sandwich – since they don’t love onions & peppers like we do!


  • 1 to 2 tbsp oil or bacon grease
  • 1 lb steak, sliced into thin, bite-size strips
  • salt & pepper, to taste
  • 1 tbsp Worcestershire sauce
  • 6 crusty buns
  • 6 slices of cheese – monterey jack, cheddar, mozzarella
  • 1 white/yellow onion, sliced into thin strips
  • 1 green pepper, sliced into thin strips

Garlic Aoli:

  • 3/4 cup mayonaise
  • 4 cloves garlic, minced (or 2 teaspoons garlic powder)
  • 2 tbsp lemon juice
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper


Make garlic aoli first so the flavours can develop. Mix ingredients in a bowl or small glass jar. Cover and refrigerate for at least 30 minutes before serving.

Preheat the oven to 350F.

In a large skillet over medium heat, heat 1 tablespoon of oil or bacon grease. Add peppers and onions and season with salt. Cook, stirring often, until caramelized, about 10 to 15 minutes. Remove onions and peppers and set aside.

Add another tablespoonful of oil or bacon grease, if required. Cook steak until your preferred doneness, about 5 to 10 minutes. For last minute of cooking, season with Worcestershire and lots of freshly ground pepper.

Meanwhile, cut buns open and place open faced on baking sheet. Toast in oven until lightly browned.

“Place garlic aoli, buns, cheese slices, onion/pepper mixture, and steak on the table or counter for a self serve buffet. “Butter” half your bun with the garlic aoli, then fill your bun with steak, then onion/pepper mixture, then place cheese on top. Pop the filled sandwiches back into the oven to melt the cheese.
