1

Before starting, preheat the oven to 450°F. Wash and dry all produce.

Cut sweet potatoes into 1/4-inch thick fries. Add sweet potatoes with 1 tbsp oil (dbl for 4 ppl) on a parchment-lined baking sheet. Season with salt and pepper, then toss to coat. Roast in the middle of the oven, flipping halfway through cooking, until golden-brown, 20-22 min.

2

While sweet potatoes roast, heat a large non-stick pan over medium heat. When hot, add 1 tbsp oil (dbl for 4 ppl), then onions. Cook, stirring occasionally, until slightly softened, 3-4 min. Add 1 tsp sugar (dbl for 4 ppl) and season with salt. Cook, stirring occasionally, until dark golden-brown, 5-6 min.

3

While onions cook, peel, then mince or grate garlic. Combine beef with panko, garlic, half the mustard, 1/4 tsp salt and 1/4 tsp pepper (dbl both for 4 ppl) in a medium bowl. (TIP: If you prefer a firmer patty, add 1 egg to the burger mixture.) Form beef mixture into two 4-inch wide burger patties (four patties for 4 ppl). Lightly press a thumbprint into each patty.

4

When onions are done, remove pan from heat. Stir in vinegar until absorbed, 1 min. Transfer onions to a small bowl. Carefully wipe pan clean. Heat the same pan over medium-high. When hot, add 1/2 tbsp oil (dbl for 4 ppl), then patties. Pan-fry, until cooked through, 4-5 min per side.**

5

While patties cook, halve buns and arrange them on another baking sheet, cut-side up. Sprinkle cheese over bottom buns. Toast in the top of the oven, until cheese melts and top buns are golden, 2-3 min. (TIP: Keep an eye on your buns so they don't burn!)

6

Stir together mayo and remaining mustard in another small bowl. Spread mayo-mustard on toasted top buns. Divide patties between buns. Top with caramelized onions. Serve with roasted sweet potatoes alongside.
