Crispy Cheddar Frico Burgers with Caramelized Onion Jam and Roasted Broccoli

These burgers are a celebration of texture and flavor. A crispy, golden-brown cheddar frico (cheese crisp) crowns a juicy beef patty, while sweet-and-tangy caramelized onion jam and ripe tomato slices add freshness. It’s a restaurant-quality burger you can make at home.

Paired with oven-roasted broccoli, this meal is both indulgent and balanced. The frico is surprisingly simple to make-just bake shredded cheddar until lacy and crisp. Once you try it, you’ll want to put it on everything.

Instructions

1. Wash and dry all produce. Preheat oven to 425°F. Halve, peel and thinly slice the onion. Slice the tomato into rounds. Split the brioche buns in half. Shape the ground beef into two patties slightly wider than the buns.
2. Toss the broccoli florets on a baking sheet with a drizzle of olive oil, salt and pepper. Roast until lightly crisped, 15-20 minutes.
3. Heat a drizzle of olive oil in a large pan over medium-high heat. Add the sliced onion and cook, stirring, until soft, 5-6 minutes. Stir in 1 tablespoon sherry vinegar and 1 teaspoon sugar. Simmer until the liquid is nearly evaporated, 1-2 minutes. Season with salt and pepper. Transfer to a small bowl and set aside.
4. Line another baking sheet with parchment paper. Place the cheddar cheese on it in two even piles. Bake until melted in the center and crispy at the edges, 5-7 minutes.
5. Meanwhile, heat a drizzle of olive oil in the same pan over medium-high heat. Season the patties all over with salt and pepper. Cook to desired doneness, 3-6 minutes per side. Carefully remove the frico from the baking sheet. Discard the parchment paper and place the buns on the sheet. Toast in the oven until golden, 3-4 minutes.
6. Fill each bun with a patty, onion jam, tomato slices, ketchup and a frico. Serve with the roasted broccoli on the side.

Recipe Tips

FAQ

Can I use a different cheese for the frico?

Yes, any hard, meltable cheese like Parmesan or Gruyère works well, but cheddar gives the best flavor and color.

How do I store leftover frico?

Store frico in an airtight container at room temperature for up to 2 days. Reheat in a 350°F oven for a few minutes to re-crisp.

Can I make the onion jam ahead of time?

Absolutely. The onion jam can be made up to 3 days in advance and refrigerated. Reheat gently before serving.
