Ingredients
Fajita Steak & Vegetables
- 1 ½ pounds flank steak or skirt steak, thinly sliced against the grain
- 2 tablespoons extra virgin olive oil, divided
- 2 tablespoons homemade steak seasoning
- 1 medium yellow onion, thinly sliced
- 3 medium bell peppers, thinly sliced (use mixed colors for best flavor and color)
- 1 pinch kosher salt
- 2 tablespoons tomato paste
- 1 teaspoon chili powder
- 1 teaspoon red chili flakes, adjust for heat preference
Sliders
- 1 package (12-count) Hawaiian rolls, (such as King’s Hawaiian)
- 6 slices Pepper Jack cheese
- 1 cup (113 g) mozzarella cheese, shredded
Garlic Butter Topping
- ¼ cup (½ stick / 57 g) unsalted butter, melted
- 2 tablespoons fresh parsley, chopped
- 1 teaspoon garlic powder
- Salt, to taste
Instructions
Marinate the Steak
- Add sliced steak to a large bowl. Toss with 1 tablespoon olive oil and steak seasoning until evenly coated.
- Cover and marinate for at least 30 minutes, or refrigerate overnight for deeper flavor.
Cook the Vegetables
- Heat a large skillet over medium-high heat with the remaining 1 tablespoon olive oil.
- Add onions and bell peppers with a pinch of salt. Sauté for 5 to 7 minutes, until softened and lightly caramelized. Remove from the pan and set aside.
Cook the Steak
- In the same skillet, cook steak in a single layer (working in batches if needed) for 3 to 5 minutes, until browned and cooked through.
- Stir in tomato paste, chili powder, and red chili flakes. Cook for 1 to 2 minutes until the tomato paste deepens in color and coats the steak.
- Return onions and peppers to the skillet and toss everything together until well combined. Remove from heat.
Assemble the Sliders
- Preheat oven to 375°F (190°C).
- Slice Hawaiian rolls in half horizontally without separating them and place the bottom half in a 9×13-inch baking dish.
- Layer with Pepper Jack cheese, then sprinkle with half of the mozzarella.
- Spoon steak fajita mixture evenly over the cheese. Top with remaining mozzarella and place the top buns over everything.
Garlic Butter Topping
- Mix melted butter, parsley, garlic powder, and salt.
- Brush garlic butter generously over the tops of the rolls.
- Cover with foil and bake for 15 to 20 minutes, until cheese is melted.
- Remove foil and bake an additional 5 to 8 minutes, until tops are golden brown.
- Brush with any remaining butter, slice, and serve warm.
