When selecting mushrooms for your Truffle Mushroom Swiss Smash, cremini mushrooms offer a richer flavor compared to button mushrooms, enhancing the truffle infusion. Using high-quality truffle oil is essential to achieve the signature earthy aroma without overpowering the dish. Ensure the ground beef has a fat content of around 20% to keep the patty juicy during the smashing process. Toasting the brioche buns with unsalted butter provides a buttery, crisp texture that complements the savory beef and mushrooms perfectly. Your homemade Truffle Mushroom Swiss Smash from Smashburger copycat menu will deliver a gourmet burger experience that rivals the original.

Substitution
The Truffle Mushroom Swiss Smash from Smashburger copycat menu calls for cremini or button mushrooms, but you can substitute with shiitake or portobello mushrooms for a different texture and deeper flavor. If truffle oil is unavailable, a few drops of truffle salt or a drizzle of high-quality olive oil can lend a similar richness. When making garlic aioli, blending roasted garlic instead of raw provides a milder, sweeter aroma that complements the savory elements. Use a cast-iron skillet or non-stick pan to saute mushrooms evenly, preventing them from becoming soggy. Your choice of bun can also be flexible; brioche offers sweetness, but a sturdy potato roll or pretzel bun works well to hold juicy patties without falling apart.
Tips
Ensure your grill or griddle is properly preheated to medium-high before placing the beef patties to achieve that perfect sear and retain juiciness. When smashing the beef balls, press firmly and evenly to create thin patties that cook quickly and evenly without drying out. Use fresh mushrooms, slice them evenly, and saute with truffle oil and butter until golden to maximize flavor and prevent sogginess on your burger. Toasting the brioche buns with butter right before assembling enhances texture and prevents them from becoming soggy from the aioli and toppings, giving your burger a satisfying crunch.
Nutritions
Your Truffle Mushroom Swiss Smash offers a rich source of protein from 1 lb of ground beef, supporting muscle repair and growth. The Swiss cheese contributes calcium and vitamin B12, essential for bone health and nerve function, while truffle-infused mushrooms add antioxidants and dietary fiber. Garlic aioli provides healthy fats and flavor, but keep in mind it adds calories and cholesterol. The toasted brioche bun delivers carbohydrates for energy, making this burger a balanced indulgence when enjoyed in moderation.
Storage
To keep your Truffle Mushroom Swiss Smash fresh, store the components separately in airtight containers; place cooked patties and sauteed mushrooms in the refrigerator for up to 3 days. The brioche buns should be stored in a bread box or sealed plastic bag at room temperature for 1-2 days to maintain softness. For longer storage, freeze cooked patties and mushrooms individually wrapped, and thaw them in the refrigerator before reheating gently on a griddle or skillet.
Variation or Alternatives
Try substituting cremini mushrooms with shiitake or oyster varieties for a bolder, earthier flavor profile. Swap Swiss cheese with Gruyere or Fontina to introduce a nuttier, creamier texture that complements the truffle-infused mushrooms. For a lighter aioli, use Greek yogurt instead of mayonnaise, enhancing the tang without overpowering your burger. You can also switch out brioche buns for pretzel buns to add a slightly sweet and chewy contrast to your Truffle Mushroom Swiss Smash.
Allergies
The Truffle Mushroom Swiss Smash contains common allergens such as dairy from Swiss cheese and butter, as well as eggs from the mayonnaise used in the garlic aioli. You should be cautious if you have allergies to mushrooms, as the dish features sauteed cremini or button mushrooms infused with truffle oil. Gluten is present in the brioche hamburger buns, which could trigger reactions in those with gluten sensitivity or celiac disease.
