Vegan Philly Cheesesteak Sliders bring savory mushrooms, sweet onion and tender peppers together under soft, golden rolls. Melted dairy-free provolone holds the filling together, while a parsley-butter topping gives the bread a tasty finish. They bake as a batch, so serving a crowd is simple. Add a crisp salad for an easy dinner or set them out for game day.
Why I Love This Recipe
These little sandwiches have plenty of savory flavor and a tender bite. Cooking the mushrooms before filling the rolls gives you rich flavor while keeping the bread from getting wet.
- Big flavor comes from browned mushrooms, garlic and a small splash of vegan Worcestershire sauce.
- Easy sharing means the rolls bake together and separate into handy portions.
- Fully plant-based ingredients include the rolls, butter, sauce and cheese.
- Simple prep lets you cook the filling ahead and assemble the sliders when needed.

How to Make Vegan Philly Cheesesteak Sliders
Cook the filling until its extra moisture is gone, then build and bake the sandwiches.
Step 1: Get the Rolls Ready
Heat the oven to 350°F (175°C).
Line a 9×13-inch baking dish with parchment, keeping the paper below the top of the dish.
Slice 12 connected vegan sweet rolls, about 12 ounces total, horizontally through the middle while keeping the slab together.
Place the bottom slab in the dish, cut side up, and set the top slab aside.
Step 2: Brown the Mushrooms
Heat 1/2 tablespoon olive oil in a 12-inch skillet over medium-high heat.
Add 1 pound trimmed oyster mushrooms, torn into thin strips, and cook for 6–7 minutes, stirring now and then, until tender and patchily brown with no puddles. Transfer them to a plate.
Repeat with 1/2 tablespoon olive oil and the remaining 1 pound oyster mushroom strips, then transfer this batch to the same plate.
Step 3: Finish the Filling
Reduce the heat to medium and add the remaining 1 tablespoon olive oil, 1 thinly sliced medium onion and 1 thinly sliced medium green bell pepper to the skillet.
Cook for 5–6 minutes, stirring often, until softened and slightly slumped.
Add 3 minced garlic cloves and cook for 30 seconds.
Return the mushrooms cooked from 2 pounds raw oyster mushrooms to the skillet.
Stir in 2 tablespoons reduced-sodium soy sauce, 1 tablespoon vegan Worcestershire sauce, 1/2 teaspoon smoked paprika and 1/4 teaspoon ground pepper.
Cook for 1–2 minutes, until the seasoning coats the filling and no loose liquid remains. Take the skillet off the heat.
Step 4: Add the Filling and Cheese
Spread all the mushroom-pepper filling evenly over the 12 bottom roll halves, reaching every roll.
Lay 12 thin square slices vegan provolone, 6 ounces total, above the filling, with one separate slice per roll. Keep the slices within their own roll spaces.
Step 5: Butter and Bake
Place the matching 12 top roll halves over the cheese, keeping the original roll grid aligned.
Mix 3 tablespoons melted vegan butter with 1 tablespoon finely chopped parsley in a small bowl.
Brush all of this mixture evenly over every roll top.
Cover the dish loosely with foil and bake for 18 minutes.
Remove the foil and bake for 5–7 minutes, until the filling is heated through, the cheese is fully melted and the tops are lightly toasted. If the cheese needs longer, cover again and continue briefly so the bread stays soft.
Step 6: Rest and Serve
Let the sliders rest for 5 minutes so the filling settles.
Cut along the roll seams and lift out the sandwiches, keeping a matching top and bottom with each portion. Cut a slider in half if you want to share smaller bites.
Serve 2 sliders per person. A green salad or vinegar-based slaw makes a fresh optional side.
Why This Recipe Works (Quick Science)
Mushrooms release water as they cook. Working in batches gives that water room to escape, which helps the mushrooms brown and keeps extra liquid out of the bread. Soy sauce and vegan Worcestershire add savory depth without needing a long simmer.
The foil holds moisture around the sandwiches while the vegan cheese softens. A short uncovered finish toasts the buttered tops. Resting the batch helps the filling stay inside when you separate the rolls.
Common Mistakes to Avoid
- Crowding the skillet traps water. Brown the mushrooms in batches.
- Leaving liquid in the filling makes the bottom bread soggy. Reduce it before assembly.
- Using cold filling can leave the center cool while the tops toast. Warm chilled filling first.
- Choosing a firm, nonmelting cheese gives a different result. Use meltable vegan slices.
- Skipping label checks can introduce dairy, eggs or fish through bread and sauces.
- Baking uncovered the whole time can dry the rolls before the cheese melts.
Pro Tips
- Tear the mushrooms into narrow strips for a tender, easy-to-bite filling.
- Buy thin square vegan provolone slices that fit the rolls. Keep the total cheese weight at 6 ounces.
- Keep the filling layer even, especially at the corners of the bread slab.
- Brush the parsley butter across every top so each portion gets the same finish.
What to Serve With Vegan Philly Cheesesteak Sliders
A green salad with a tangy vinaigrette balances the rich bread and cheese. Vinegar-based cabbage slaw adds crunch and works well for a casual meal. Roasted potato wedges are another easy option when you want a heartier plate.
Make-Ahead Tips and Storage
Cook the filling up to 2 days ahead. Cool it promptly, refrigerate it in a covered container and reheat it before assembling. Keep the bread separate until baking.
Refrigerate leftover baked sliders within 2 hours and use within 3–4 days. Reheat covered at 350°F (175°C) for 12–15 minutes, or until the center reaches 165°F (74°C). Uncover briefly to refresh the tops.
Freeze cooled filling for up to 2 months. Thaw it in the refrigerator and cook off any extra moisture before using. Freshly assembled rolls have the best texture.

Frequently Asked Questions (FAQ)
Q: Are Hawaiian-style rolls vegan?
A: Some are, but many contain dairy or eggs. Look for a clearly labeled vegan version and check for honey too.
Q: Can I use portobello mushrooms?
A: Yes. Use the same trimmed weight and slice them thinly. Cook in batches until their released water is gone.
Q: Which vegan cheese works best?
A: A meltable vegan provolone gives a mild, savory flavor. Choose thin slices and follow any melting tips on the package.
Q: Can I use regular Worcestershire sauce?
A: Check the label. Many regular versions contain anchovies, so this recipe needs a vegan version.
Q: Can I make these gluten-free?
A: Use gluten-free vegan rolls, tamari and a gluten-free vegan Worcestershire sauce. Check the cheese label as well. The roll size may change the pan fit and yield.
Q: Can I leave out the green pepper?
A: Yes. Replace it with a similarly sized red bell pepper for a sweeter filling.
Q: Why is my filling watery?
A: The mushrooms may need more time or a less crowded skillet. Let the liquid evaporate before putting the filling on the bread.
Q: Can I assemble the sliders the night before?
A: Keep the cooked filling separate from the bread overnight. Assemble shortly before baking for a firmer bottom roll.
Q: Can I double the recipe?
A: Yes. Use two baking dishes and brown the mushrooms in more batches. Switch the dishes between oven racks during baking and check that both centers are heated through.
