Umami is a distinct flavor profile – aside from sweet, sour, salty, and bitter – that can best be described as savory, incredibly flavorful, and/or indescribably delicious. This dish has umami in spades! We start with a miso-marinated beef burger topped with all the fixings on a toasted brioche bun. It’s paired with Parmesan sweet potato fries for that extra special something.

Recipe Steps
You Will Need
- Olive Oil
- Salt
- Pepper
- Cooking Spray
- 1 Baking Sheet
- 1 Small Bowl
- 1 Mixing Bowl
- 1 Large Non-Stick Pan
Before You Cook
-
1 Prepare the Ingredients
Cut sweet potato into ½" thick fries. Peel and slice red onion into ¼” thick rounds. Cut mushrooms into ¼” slices. Rinsing starch off cut potatoes helps fries crisp up in oven.
-
2 Bake Fries and Make Aioli
Place sweet potato fries on prepared baking sheet and toss with 2 Tbsp. olive oil and 1 tsp. salt. Spread into a single layer and bake until browned and tender, 25-30 minutes, turning after 15 minutes. Rest 5 minutes on baking sheet to firm up after cooking. Combine mayonnaise, 2 tsp. miso (reserve remaining for burgers), and sun-dried tomato pesto in a small bowl and set aside.
-
3 Make the Burgers
Combine ground beef, remaining miso, half the Parmesan (reserve remaining for fries), 1 tsp. salt, and 1 tsp. pepper in a medium mixing bowl. Form four burgers 5” in diameter. Using your fingers, make a small dimple in middle of each burger. This will prevent patties from bulging when cooked and create an evenly flat burger.
-
4 Toast the Buns
Heat a large non-stick pan over medium-high heat. Brush cut side of buns with 1 Tbsp. olive oil and toast, cut side down, until golden brown, 1-2 minutes. Reserve pan for cooking burgers (no need to wipe clean).
-
5 Cook the Burgers and Mushrooms
Return pan to medium-high heat and add 2 tsp. olive oil and burgers to hot pan. Cook on first side until brown, 3-4 minutes. Flip burgers and add mushrooms. Cook until mushrooms are brown and burgers reach a minimum internal temperature of 145 degrees, 4-5 minutes. Transfer burgers to a plate and top with sliced white cheddar. Depending on how well you like your burgers done, you may end up removing them before mushrooms have finished browning.
-
6 Plate the Dish
Arrange sweet potato fries on plate and garnish with remaining Parmesan. Place a bottom bun on plate and top with tomato-miso aioli, burger, mushrooms, and red onions. Cover with top bun.
