Ultimate Cheeseburger Fondue
Ingredients
- For the Beef Patties:
- 2 lbs ground beef 90/10
- 2 cups thinly sliced onions
- 1 tablespoon kosher salt
- 1 tablespoon black pepper
- 1 tablespoon garlic powder
- For the Burgers:
- 8 –10 slices cheese American or mild cheddar
- ½ cup mayonnaise
- 4 –6 burger buns toasted
- For the Cheese Sauce:
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 cup whole milk
- 1 cup shredded Jack cheese or cheddar blend
- 1 teaspoon Dijon mustard
- 1 teaspoon cayenne powder
- Kosher salt to taste
Instructions
- Make the Cheese Sauce:
- Heat a skillet over medium heat. Melt the butter, then whisk in the flour and cayenne powder for 1–2 minutes.
- Slowly add the milk, stirring constantly, until the sauce thickens.
- Mix in Dijon mustard, then stir in shredded cheese until smooth. Thin with extra milk if necessary. Keep warm.
- Prepare the Burger Patties:
- Divide ground beef into ¼-pound portions and roll into balls. Chill in the fridge until ready to cook.
- Heat a cast iron skillet or griddle over high heat until very hot.
- Place a beef ball in the skillet, top with a handful of sliced onions, cover with parchment, and press firmly to “smash” the patty.
- Season with salt, pepper, and garlic powder. Cook 1–2 minutes, then flip, season the other side, and top with a slice of cheese to melt. Repeat for remaining patties.
- Assemble the Burgers:
- Spread mayonnaise on toasted buns. Layer 1–2 patties on each bun, add more mayonnaise if desired, and top with the bun. Slice in half.
- Serve with Fondue:
- Pour warm cheese sauce into a hot skillet and nestle the burger halves cheese-side down into the sauce. Serve immediately and enjoy.
