Preheat the oven to 475°F (245°C). If using a pizza stone, place it in the oven while preheating.
Heat 1 tbsp olive oil in a skillet over medium-high heat. Sauté the onions and peppers for 4–5 minutes until soft. Add garlic and cook for another 30 seconds.
4 tablespoons olive oil, 1 small onion, 1 small green bell pepper, 1 small red bell pepper, 1 clove garlic
Add the steak to the pan and cook until just browned (about 1–2 minutes). Season with salt and pepper. Remove from heat.
8 oz thinly sliced steak, Salt and pepper
On a floured surface, roll or stretch your pizza dough into a 12–14-inch round. Transfer to a parchment-lined baking sheet or pizza peel if using a stone. Brush lightly with olive oil.
1 ball of pizza dough
Top with provolone, then add the steak and veggie mixture. Finish with shredded mozzarella cheese on top.
½ cup provolone cheese, 1½ cups shredded mozzarella cheese
Bake for 12–15 minutes, or until the crust is golden and the cheese is bubbly and starting to brown.
Slice and serve hot.
Notes
Room temp dough = better stretch. If using refrigerated dough, let it rest at room temperature for 30–60 minutes before shaping so it doesn't spring back.
Use freshly shredded cheese for better melt and flavor. Pre-shredded cheese often contains anti-caking agents that can affect texture.
Blend provolone and mozzarella for that iconic Philly flavor. You could even throw in some white American cheese if you want to go full cheesesteak-style.
If baking on a sheet pan, go for the lowest oven rack—you’ll get a crispier bottom.
