Ingredients
1개 onion, 1꼬집 salt, 2cup whole milk, 2cup shredded Gruyère, 0.25cup grated Parmesan, 0.5cup cubed white cheddar, 1cup French onion dip, 2tsp French onion dip seasoning, 9ounces ground beef, 3tbsp yellow mustard, 3개 buns, 0.5cup crispy onions, 1꼬집 fresh thyme
Instructions
1. Slice the onion very thinly using a mandoline. Toss with salt to draw out moisture.
2. Heat whole milk in a pan over medium heat until bubbly on the sides and steaming.
3. Gradually add shredded Gruyère cheese, whisking until fully incorporated. Repeat with grated Parmesan and cubed white cheddar.
4. Stir in French onion dip and French onion dip seasoning until smooth and all lumps are gone.
5. Form 3-ounce portions of ground beef into loose balls. Apply yellow mustard to the bottom of each beef ball.
6. Place the mustard-side down beef balls on a hot griddle. Season the top of the beef with French onion dip seasoning.
7. Place a generous amount of thinly sliced onions on top of each beef ball.
8. Smash the burgers down with a burger press. Cook until a nice crust forms, then flip.
9. Assemble the burger: place the bottom bun, then a patty with cheese, another patty with cheese, and a third patty with cheese.
10. Place the top bun on the burger. Use a metal ring to create a well on top of the bun.
11. Pour the warm cheese sauce into the well, allowing it to overflow down the sides of the burger.
12. Remove the metal ring. Garnish with crispy onions and fresh thyme.
