Mushroom cheesesteak – it feels like we’ve stumbled into a culinary wonderland where hearty flavors meet plant-based goodness.
As a self-proclaimed food enthusiast, I can’t help but rave about this delightful creation. Once you take a big bite, you’ll understand why I’m so excited.
It’s a dish that bridges the gap between hearty comfort food and the satisfying crunch of fresh ingredients.
Picture this: you’re at a picnic, and the sun is shining. You pull out your sandwich to share and, instead of the typical meat-filled cheesesteak, you showcase a colorful mushroom version. The reactions are priceless.
Everyone wants a taste, and soon enough, they’re asking for the recipe.
So what’s the scoop on this amazing dish? Let’s dive in!

What is Mushroom Cheesesteak?
At its core, the mushroom cheesesteak is a plant-based twist on the classic cheesesteak sandwich hailing from Philadelphia. Instead of steak, we’re using mushrooms. They provide a savory, earthy flavor that serves as the perfect base for a melty cheese layer and sautéed veggies.
This dish is as much about texture as it is about flavor. The mushrooms, when sliced thick and cooked just right, have a meaty quality that satisfies those cravings for a hearty sandwich.
Paired with grilled onions and bell peppers, the combination creates a harmonious balance of taste and enjoyment in every bite.
What Does It Taste Like?
Imagine biting into a warm sub roll, the soft bread cradling a filling made of sautéed mushrooms, sweet onions, and vibrant bell peppers, all topped with gooey provolone cheese.
The flavors meld together so perfectly, you might forget that it’s meatless. It’s a savory explosion that dances on your tastebuds, bringing comfort and satisfaction all at once. Not to mention, the aroma alone while cooking can make your kitchen feel welcoming and homey.
Why This Recipe Works
1. Umami Overload
Mushrooms are renowned for their umami flavor, which means they provide that savory punch we often crave in comfort food. When cooked, they become incredibly rich and flavorful, offering taste without the heaviness of meat.
2. Textural Harmony
The combination of ingredients creates a wonderful medley of textures. The softness of the bread and mushrooms contrasts beautifully with the crispness of the bell peppers and onions. Each bite reveals a different layer, keeping your palate intrigued.
3. Versatile Ingredients
This mushroom cheesesteak recipe plays well with various ingredients. You can throw in whatever veggies you have on hand, making it adaptable for every season. Not a fan of bell peppers? Switch them out for roasted zucchini or even some spinach. Flexibility in cooking is a vital aspect of any recipe.
4. Easy to Prepare
Let’s face it: in our fast-paced lives, we look for meals that don’t take forever to whip up. This cheesesteak takes just a few ingredients and minimal preparation. It’s perfect for a quick weeknight dinner or a casual weekend gathering.
Ingredients for Mushroom Cheesesteak
- 4 6-inch sub rolls, toasted if desired
- 4 slices smoked provolone cheese
- 2 tablespoons extra virgin olive oil, divided
- 2 large onions (any variety: white, yellow, or red), or 3 small onions
- 16 ounces cremini or button mushrooms, thickly sliced
- 1 red bell pepper, julienned
- 1 green bell pepper, julienned
- ½ teaspoon fine sea salt
- 1 tablespoon low-sodium soy sauce
- 1 teaspoon Worcestershire sauce
- 1 teaspoon dried Italian seasoning (replaces oregano for more complexity)
- ½ teaspoon garlic powder
- 1 teaspoon cornstarch

Step by Step Instructions
Step 1: Prepare the Ingredients
Start by gathering all items on your kitchen counter. Wash the mushrooms, and slice them thickly. Chop the onions and julienne the bell peppers. Having everything prepped makes the cooking process smoother, like a well-rehearsed play.
Step 2: Sauté the Onions
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the onions, sprinkle with a pinch of salt, and cook for about 5 minutes until they turn translucent and start to caramelize. Stir them occasionally; we want some lovely golden edges.
Step 3: Add the Mushrooms
Once the onions are ready, add the sliced mushrooms to the skillet. Sauté for another 8-10 minutes, or until they are golden brown and have released their moisture. The kitchen should start smelling fantastic!
Step 4: Include the Bell Peppers
Next, toss in the julienned bell peppers. Cook everything together for about 5 more minutes, until the peppers are tender. Stir in the soy sauce, Worcestershire sauce, garlic powder, and Italian seasoning, and let those flavors meld together for a couple of minutes.
Step 5: Thicken the Fillings
In a small bowl, mix the cornstarch with a tablespoon of water to create a slurry. Add this to the pan, stirring quickly to incorporate. It will help bind the filling and add a bit of creaminess.
Step 6: Assemble the Sandwiches
Preheat your oven to 350°F (175°C). Slice the toasted sub rolls lengthwise, but don’t cut all the way through. Place the rolls on a baking sheet and layer with the mushroom filling from the skillet. Top each with a slice of smoked provolone.
Step 7: Bake to Perfection
Pop the baking sheet in the oven for about 10 minutes, or until the cheese is melted and bubbly. You want that glorious cheese to stretch when you take a bite!
Notes
Here are a few tips to ensure your mushroom cheesesteak turns out delicious:
- Choose the Right Mushrooms: While cremini or button mushrooms work well, you can also experiment with portobello or shiitake for a deeper flavor.
- Don’t Rush the Sauté: Allow the onions and mushrooms to develop their flavors by cooking them until they are golden brown.
- Add Spice: If you’re craving a little heat, consider adding sliced jalapeños or crushed red pepper flakes to the mix.
- Make it Vegan: Swap the provolone for a plant-based cheese alternative to suit vegan diets.
- Prep in Advance: You can prepare the mushroom filling a day ahead. Just store it in the fridge and then reheat before assembling the sandwiches.
How to Store the Leftovers?
If you happen to have any leftovers (which is not likely!), allow them to cool down, then transfer the filling and bread separately into airtight containers. Stored this way, it should last in the fridge for up to 3 days.
When you’re ready to eat, simply reheat the filling and assemble the sandwich fresh.
Sides for Mushroom Cheesesteak
Pairing your cheesesteak with the right sides can elevate the meal even more. Here are some ideas:
1. Crispy Sweet Potato Fries
These fries offer a slight sweetness that balances the savory mushroom cheesesteak. It’s a match made in heaven. Toss sweet potato wedges in olive oil and spices, then roast until crispy.
2. Classic Coleslaw
The crunch and tangy flavors of coleslaw make it a perfect counterpoint to the richness of the cheesesteak. Whether you prefer a mayo-based or vinegar-based slaw, either choice provides a refreshing bite.
3. Garlic Roasted Brussels Sprouts
In need of greens? Toss Brussels sprouts in olive oil and garlic, then roast until crispy and brown. They add a bit of flair to your plate while complementing the sandwich perfectly.
4. Cucumber Salad
For a lighter option, a cucumber salad with a drizzle of olive oil, vinegar, and a sprinkle of salt works wonders. It adds a crisp texture to your cheesesteak meal.
Alternative Choices to the Ingredients
Sometimes, cooking has to be flexible. If you find yourself missing certain ingredients, not to worry!
1. Cheese Swap
If provolone isn’t available, try mozzarella for a gooey texture or cheddar for a bolder flavor.
2. Different Bread
Hoagie rolls are traditional, but any sandwich bread will do. Think ciabatta, baguette, or even a wrap!
3. Seasonal Veggies
Cooking with the seasons means using what’s fresh. Zucchini, summer squash, or even spinach can be delightful stand-ins for bell peppers.
4. Non-Soy Sauce Option
If soy sauce is off your plate due to dietary reasons, consider Tamari for a gluten-free alternative. Coconut aminos are another great substitute that adds a hint of sweetness.

Conclusion
The mushroom cheesesteak is more than just a meatless option; it’s a celebration of flavor, texture, and creativity. When you merge the umami-rich mushrooms with fresh veggies and melty cheese, you create something special.
This dish tells the story of the classic cheesesteak reinvented for everyone.
