If you’ve ever ordered the Flying Dutchman from In-N-Out’s not-so-secret menu, you know it’s a cheese-and-beef lover’s dream. But if you’ve also thought, “This could be beefier... and maybe a little less salty,” then you’re not alone.
That’s exactly why we decided to recreate it on the LoCo 16" Tabletop SmartTemp Griddle—with a few flavorful upgrades. The result? Honestly, one of the best burgers we’ve ever had.
🔥 Griddle It Like a Pro
The LoCo SmartTemp Griddle makes outdoor cooking precise and effortless with exact temperature control and even heating across its 265 sq. in. surface. Set it to 450°F, and you’re ready to sear, smash, and caramelize like a champ.
Ingredients
For the Burger:
-
1 large yellow onion (cut into thick rounds)
-
1–1.25 lbs ground beef (preferably 80/20)
-
1 tbsp Dale’s seasoning sauce
-
Salt and pepper, to taste
-
4 slices American cheese
-
Butter (for caramelizing onions)
For the Sauce:
-
2 tbsp mayonnaise
-
1 tbsp ketchup
-
1 tsp mustard
-
1 tsp red wine vinegar
-
1 tsp salsa verde
Directions
-
Preheat Griddle
Turn your LoCo SmartTemp Griddle to 450°F and let it heat evenly. -
Prepare the Onion “Buns”
Brush your onion rounds with butter and place them on the griddle. Let them cook slowly, flipping occasionally, until softened and deeply caramelized—about 10–12 minutes. -
Mix & Shape the Beef
Combine the ground beef with Dale’s sauce, then form into loosely packed balls (about ¼ lb each). -
Smash Patties
Place the beef balls on the hot griddle and smash them flat using a spatula or grill press. Season with salt and pepper. Cook until browned and crispy on one side, flip, then add a slice of cheese to each patty. Let melt. -
Make the Sauce
Stir together mayo, ketchup, mustard, red wine vinegar, and salsa verde in a small bowl. Taste and adjust to your liking. -
Assemble Your Burger
Use two onion rounds as the “buns” and sandwich one or two patties in between with a generous spoonful of sauce.
