What is the Shake Shack Shroom Burger?
The Shake Shack Shroom Burger isn’t just any burger – it’s a plant-based alternative that shines through its simplicity and flavor. This recipe involves a large portobello mushroom cap that’s stuffed with a savory blend of cheeses, coated in a crispy breadcrumb shell, and fried until golden. It’s served on a toasted potato bun with fresh toppings and ShackSauce, a semi-secret concoction that adds a tangy, creamy finish.
Why is it loved by so many? Because it delivers that satisfying umami without any meat! Each bite strikes the perfect balance of crunch and creaminess, making it utterly indulgent. That’s the magic!
What Makes This Recipe Different from Other Shake Shack Shroom Burger Recipes?
While many variations of shroom burgers exist, what sets this recipe apart is its blend of flavors and the use of fresh ingredients. Many might opt for low-quality cheese or over-salting the mushroom. However, this recipe elevates the experience by meticulously selecting Muenster and Cheddar cheeses. The combination of spices is also different, adding depth without overpowering the star of the dish–the mushroom itself.
The texture here is paramount. The panko breadcrumbs lend a light crispness, creating a beautiful contrast against the juicy mushroom. Also, let’s not forget the ShackSauce; it’s a flavor-packed addition that truly brings everything together.
How Does It Taste?
First off, the way the umami-rich portobello blends with melted cheeses is a taste sensation. Then there’s that crunch from the breadcrumbs — it’s like a hug for your taste buds. The freshness of the lettuce, the sweetness of the tomato, and the zing of the ShackSauce all work in harmony to create a burger experience like no other.
Each bite feels satisfying and filling without that greasy, heavy feeling. People often say the taste is reminiscent of a classic cheeseburger, but it feels exciting and fresh due to the innovative ingredients.
Ingredients You’ll Need to Make This Dish
To craft your very own Shroom Burger, gather the following ingredients:
Mushroom Caps & Filling:
- 4 portobello mushroom caps, approximately 4 inches in diameter
- 1/4 cup canola oil, plus extra for frying
- 1/2 teaspoon sea salt
- 1/8 teaspoon freshly cracked black pepper
- 1 1/2 cups plus ¼ teaspoon all-purpose flour, separated
- 3 large eggs plus 1 egg yolk, separated
- 2 cups panko breadcrumbs
- 1/2 teaspoon finely minced white onion
- 1/8 teaspoon minced garlic (about ¼ clove)
- 1 1/2 cups shredded muenster cheese
- 1/2 cup shredded sharp cheddar cheese
- A pinch of sea salt
- 4 toasted potato hamburger buns
- 4 crisp green leaf lettuce leaves
- 8 slices of ripe plum tomatoes, cut into ¼-inch-thick slices
- 1 teaspoon finely chopped fresh basil
- 1/4 teaspoon smoked paprika
ShackSauce:
- 1/2 cup creamy mayonnaise
- 1 tablespoon Dijon mustard
- 3/4 teaspoon tomato ketchup
- 1/4 teaspoon dill pickle brine
- 1 teaspoon freshly squeezed lemon juice
- 1/2 teaspoon honey
- A pinch of cayenne pepper

Step-by-Step Instructions
Step 1: Prepare the Mushroom Caps
Start by cleaning your portobello mushroom caps. Remove the stems and gently scrape out the gills with a spoon. This helps in getting rid of any bitterness and allows for more stuffing. Brush the caps with canola oil, salt, and pepper on both sides. Set them aside while you prepare the filling.
Step 2: Make the Filling
In a bowl, mix together the cheeses, minced onion, garlic, smoked paprika, and a pinch of sea salt. This cheesy goodness is what makes the burger so irresistible. Make sure it’s combined well.
Step 3: Stuff the Mushrooms
Take the cheese mixture and generously stuff it into each mushroom cap. Press it down gently, ensuring you have a good amount filling.
Step 4: Prepare the Breading Station
In one bowl, place 1 ½ cups of flour. In a second bowl, whisk together the eggs and yolk. Finally, in a third bowl, add the panko breadcrumbs.
Step 5: Coat the Mushrooms
First, dredge each stuffed mushroom cap in the flour, shaking off the excess. Next, dip it in the egg mixture, covering it thoroughly. Lastly, coat it with the panko breadcrumbs, ensuring it’s evenly covered.
Step 6: Fry the Mushrooms
Heat the canola oil in a frying pan over medium-high heat. Once hot, carefully place the breaded mushrooms in the pan. Fry for about 3-4 minutes on each side, or until golden brown and crisp. Remove them from the pan and place them on paper towels to absorb any excess oil.
Step 7: Toast the Buns
While the mushrooms are frying, lightly toast your potato hamburger buns. You want them warm with a slight crust. This will hold up well against the moist shroom burger.
Step 8: Assemble Your Burger
Lay a crisp piece of lettuce on the bottom half of each toasted bun. Place the golden-brown fried mushroom on top, add two slices of tomato, and sprinkle with chopped basil. Drizzle or spread ShackSauce on the top bun, then place it over the stack.
Tips & Tricks on Making Shake Shack Shroom Burger
Here are some expert tips that can elevate your shroom burger game:
- Use Fresh Ingredients: The fresher your mushrooms, vegetables, and herbs, the tastier your burger will be.
- Experiment with Cheeses: Try mixing different cheese types for a more complex flavor. A creamy brie or sharp fontina could be delightful.
- Don’t Skip the ShackSauce: This sauce brings everything together. You can make a bigger batch and use it for salads or sandwiches.
- Control the Oil Temperature: Make sure the oil is hot enough before frying. This prevents the mushrooms from absorbing too much oil and becoming soggy.
- Prep Ahead of Time: You can prepare the mushrooms and filling a day ahead. Just store everything separately in the fridge and assemble when ready to fry.

How Do I Store This Dish?
If you have leftovers — and trust me, it’s easy to eat more than one — store them properly! Place the assembled burger in an airtight container. Keep the burger and sauce separate to maintain texture. It should last in the fridge for 2-3 days. Reheat gently in an oven or toaster oven to maintain that crispiness.
What Other Substitutes Can You Use in the Shake Shack Shroom Burger Recipe?
If you want to make some adjustments to the original recipe, here are five different substitutes you could consider:
- Lentils: Substitute the mushroom cap with a lentil patty for a lighter, protein-rich option. Make sure to season it well.
- Cauliflower Steaks: Instead of mushroom caps, try thick slices of cauliflower. They can absorb flavors beautifully and add that desired texture.
- Chickpea Patties: For a different take, you could use spiced chickpea patties instead of filling a mushroom.
- Zucchini Slices: Large, grilled zucchini rounds can also work. Just roast them to bring out their sweetness.
- Spinach and Feta Filling: For a Mediterranean twist, use spinach and feta instead of the cheese blend in the mushroom.
