One word: truffles. These fungi, found underground, are prized for their rarity, rich flavor, and heady aroma. We celebrate these gems by starting with a juicy beef burger, crowned with creamy Swiss cheese, sautéed mushrooms, crisp onions and arugula, a hearty slice of tomato, and a truffle-spiked mayo that’s nothing short of addicting. Pair it with a side of homemade (by you!) steak fries for quite possibly the most unique and flavorful burger ever.
Due to our just-in-time sourcing model, we may have to send you a

sent to you meets our high quality standards. We’ll keep you
informed should a switch occur, so please check the ingredient
labels in your meal bag.
You Will Need
Grill Pan or Outdoor Grill
Medium Non-Stick Pan
Before You Cook
Make the Steak Fries
Cut potatoes lengthwise into ½" wedges. Place potatoes, 1 Tbsp. olive oil, ½ tsp. salt and ¼ tsp. pepper on prepared baking sheet and toss to evenly coat. Spread into a single layer and roast 12-15 minutes. Remove from oven, flip fries, and roast until fries are browned and crisp, 12-15 minutes. Remove from oven and set aside. While fries roast, prepare ingredients.
Prepare the Ingredients
Slice tomato into ¼" rounds. Cut mushrooms into ¼" slices. Peel onion and slice into thin rounds. Halve pretzel buns, if necessary.
Cook the Burgers
Warm a grill pan or outdoor grill to medium-high heat and lightly coat with cooking spray. Shape ground beef into two equal-sized patties slightly larger than pretzel bun diameter, and season each side with ½ tsp. salt and a pinch of pepper. Place patties on hot grill and cook until burgers reach a minimum internal temperature of 160 degrees, 4-6 minutes per side. When burgers are almost done, top with cheese and let melt slightly. Remove from grill.
Cook the Mushrooms
Place a medium non-stick pan over medium heat and add 1 tsp. olive oil. Place mushrooms in hot pan and cook, stirring occasionally, until soft, aromatic, and caramelized, 5-8 minutes. Remove from burner and set aside.
Make the Truffle Mayo
Combine mayonnaise and truffle oil (start with half, taste, and add more if desired) in a small bowl. Season with a pinch of salt and pepper and stir until fully incorporated.
Plate the Dish
If desired, lightly toast pretzel buns until warm. Spread truffle mayo on tops and bottoms of buns. Add burger patty, mushrooms, tomato and onion (to taste). Top with arugula and top bun. Arrange fries in a pile next to burger and serve any remaining truffle mayo on the side.
