Instructions

1. Preheat oven to 425°F with rack in upper position. Wash and dry all produce. Halve, peel and thinly slice the red onion. Slice tomatoes into rounds. Split brioche buns in half. Shape ground beef into 4 patties slightly wider than the buns.
2. Toss broccoli florets on a baking sheet with a drizzle of olive oil, salt and pepper. Roast until slightly crispy, about 15 minutes.
3. Meanwhile, heat a drizzle of olive oil in a large skillet over medium-high heat. Add sliced onion and cook, stirring, until soft, 5-6 minutes. Stir in sherry vinegar and sugar; simmer until liquid nearly evaporates, 1-2 minutes. Season with salt and pepper. Transfer onion jam to a small bowl; set aside.
4. Line another baking sheet with parchment paper. Place cheddar cheese in 4 equal piles on the parchment. Bake until melted in the center and crispy at edges, 5-7 minutes. If you don’t have parchment, use a spatula to transfer the frico to a plate immediately after baking.
5. While frico bakes, heat a drizzle of olive oil in the same skillet over medium-high heat. Season patties with salt and pepper. Cook to desired doneness, 3-6 minutes per side. Meanwhile, remove frico from baking sheet, discard parchment and place buns cut-side down on the sheet. Toast in oven until golden, 3-4 minutes.
6. Assemble burgers: bottom bun, patty, onion jam, tomato slices, ketchup and a frico crisp. Top with bun. Serve with roasted broccoli on the side.

Recipe Tips

FAQ

Can I use a different cheese for the frico?

Yes, any hard cheese that melts well, like Parmesan or Gruyère, will work. Cheddar gives a classic flavor and nice golden color.

How do I store leftover onion jam?

Store the caramelized onion jam in an airtight container in the refrigerator for up to 5 days. It’s great on sandwiches or as a topping for grilled meats.

Can I make the frico ahead of time?

Absolutely! Bake the frico, let them cool completely and store in an airtight container at room temperature for up to 2 days. Re-crisp in a 300°F oven for a few minutes if needed.
