Before starting, preheat the oven to 450°F and wash and dry all produce.In Step 3, when shaping your patties, carefully make a thumbprint in the middle of each patty. This will help it keep its shape while cooking! Cut sweet potatoes into 1/4-inch thick fries. Toss sweet potatoes with 1 tbsp oil (dbl for 4 ppl) on a parchment-lined baking sheet. Season with salt and pepper. Roast in the middle of the oven, flipping halfway through cooking, until golden-brown, 20-22 min.
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.
While onions cook, peel shallot, then finely grate. Peel, then mince or grate garlic. Combine beef, garlic, shallot, half the mustard, 1/2 tbsp cornstarch and 1/2 tsp salt (dbl both for 4 ppl), in a medium bowl. Season with pepper. Form mixture into two 4-inch wide patties (four patties for 4 ppl). Lightly press a thumbprint into each patty.
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 heat. When hot, add 1/2 tbsp oil (dbl for 4 ppl), then patties. Pan-fry, until cooked through, 4-5 min per side.**
While patties cook, halve buns and arrange them on another baking sheet, cut-side up. Sprinkle cheese over bottom buns. Toast in top of oven, until cheese melts and top buns are golden, 4-5 min. (TIP: Keep an eye on your buns so they don't burn!) (NOTE: For 4 ppl, use one of the same baking sheets from the sweet potatoes.)
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 sweet potatoes alongside.
