Crispy Cheddar Frico Cheeseburgers
with Caramelized Onion Jam and Roasted Broccoli
We’ve taken cheeseburgers to the next level with the help of a little something called frico (aka cheese crisps). They look fancy-schmancy, but making them simply involves baking cheddar cheese until it reaches crispy, golden-brown perfection. On top of burgers with onion jam, tomatoes, and ketchup, they feel like a crowning achievement in topping technology.
Produced in a facility that processes eggs, milk, fish, peanuts, sesame, shellfish, soy, tree nuts, and wheat.

Adjust racks to middle and top positions and preheat oven to 425 degrees. Wash and dry all produce. Halve, peel, and thinly slice onion. Slice tomato into rounds. Halve buns. Shape beef into two equal-sized patties (four for 4 servings), each slightly wider than buns.
Toss broccoli on a baking sheet with a drizzle of olive oil and a pinch of salt and pepper. Roast on top rack until browned and slightly crispy, 15-20 minutes.
Heat a drizzle of olive oil in a large pan over medium-high heat. Add onion and cook, stirring, until soft, 5-6 minutes. Stir in half the vinegar (use all for 4 servings) and 1 tsp sugar (2 tsp for 4 servings). Simmer until liquid is nearly evaporated, 1-2 minutes. Season with salt and pepper. Turn off heat; transfer to a small bowl. Wipe out pan.
Grease a second baking sheet with cooking spray. (TIP: Alternatively, lightly oil baking sheet or line with parchment.) Place cheddar on sheet in two even piles (four for 4 servings). Bake on middle rack until melted in middle and crispy at the edges, 5-7 minutes. Let cool on sheet for about a minute after removing from oven, then transfer to a plate using a spatula to cool further.
Season patties all over with salt and pepper. Heat a drizzle of olive oil in pan used for jam over medium-high heat. Add patties and cook to desired doneness, 3-6 minutes per side. Meanwhile, place buns on sheet used for cheddar frico. Toast in oven until golden, 3-4 minutes.
Fill each bun with a patty, onion jam, tomato slices, ketchup, and a cheddar frico. Serve with broccoli on the side.
