What You’ll Need to Make Philly Cheesesteak Phyllo Bites

4 slices of roast beef from the deli, diced small
½ cup finely diced green pepper
1 small onion, finely diced
½ to ¾ cup finely diced mushrooms
1½ teaspoons Weber Savory Steakhouse seasoning
½ cup shredded provolone cheese
30 mini phyllo shells

How to Make Philly Cheesesteak Phyllo Bites

Step 1: Preheat the oven

Set the oven to 350°F and line a baking sheet with parchment paper. This makes cleanup easier and helps the shells bake evenly.

Step 2: Chop everything

Dice the roast beef, onion, mushrooms, and green pepper into small, bite-sized pieces. Tip: Keeping everything uniform helps it all fit neatly into the shells.

Step 3: Soften the vegetables

In a skillet over medium heat, cook the green pepper and onion for about 5 minutes. They should start to soften but still hold a little crunch.

Step 4: Add the roast beef, mushrooms, and seasoning

Stir in the roast beef, mushrooms, and steak seasoning. Let everything cook together for another 5 minutes or so, just until the mixture is heated through and blended well.

Step 5: Mix in the cheese

Turn off the heat and add half of the shredded provolone. Stir until the cheese melts slightly and the filling starts to hold together.

Step 6: Fill the shells

Spoon the warm mixture into the phyllo shells, then top each one with a pinch of the remaining cheese.

Step 7: Bake

Place the filled shells on the prepared baking sheet and bake for 10 minutes, just until the cheese is melted and the shells are crisp.

Step 8: Serve warm

Let them cool for a minute or two, then serve while still warm.

A Few Helpful Tips

Go with a firmer provolone that shreds well and melts cleanly.
Keep the veggies diced small so everything fits neatly in the shells.
The steakhouse seasoning adds depth, but feel free to adjust to taste.
Prep the filling ahead and store it in the fridge, then fill and bake when ready.
Use parchment or foil for an easy transfer and less cleanup.

These come together quickly and land well every time. Nothing complicated. Just something warm and savory that’s easy to make and even easier to remember for next time.
