Bacon cheeseburger patty melts take 2 lbs of 80/20 ground beef formed into thin patties, seasoned and cooked on a hot griddle until deeply browned, then topped with American cheese, stacked double on inverted brioche buns with crispy bacon, sweet caramelized onions cooked in the bacon fat, chipotle mayo, and pickles. The move that makes these different is inverting the buns so the soft interior side faces outward onto the griddle, which creates a crispy, toasted surface that feels like a diner-style patty melt while keeping the structured shape of a burger. The whole thing gets pressed and toasted on the griddle as a final step until both sides are golden brown and the cheese is melting through every layer. Makes 4 to 6 patty melts.

Why Inverting the Buns Changes Everything

Soft Side Out, Crispy Side In

A standard burger bun has a smooth, domed exterior and a soft, porous interior. When you eat a regular burger, the soft interior absorbs juices and condiments, which can make it soggy. Flipping the bun inside out puts that soft, porous surface directly on the griddle, where it toasts into a crispy, golden crust with a texture closer to grilled cheese or a classic patty melt. The smooth exterior becomes the interior of the sandwich, which holds up better against the melted cheese and chipotle mayo.

Diner Patty Melt Meets 5 Guys Burger

Traditional patty melts use sliced bread (usually rye or sourdough) that gets buttered and griddled. By inverting a brioche bun and pressing it on the griddle, you get the same crispy, toasted exterior of a patty melt but with the structural hold and soft interior of a burger bun. The result is a hybrid that eats like a burger but has the crispy, pressed texture of a diner-style melt on the outside.

Building Flavor in Layers

Bacon First, Onions in the Bacon Fat

Cook the bacon on the griddle until crispy and set it aside. Instead of wiping the griddle clean, add the sliced sweet onions directly into the rendered bacon fat. The onions absorb the smoky, salty pork flavor as they soften and caramelize, which means the finished onion layer carries bacon flavor through the entire sandwich even beyond the strips themselves. Cook the onions until they are soft, golden, and sweet, which takes about 8 to 10 minutes over medium heat.

Thin Patties for Maximum Crust

Form the 80/20 ground beef into thin patties rather than thick ones. Thin patties develop more surface area for the Maillard reaction on the griddle, which means a deeper, crustier sear on both sides. Since you are stacking two patties per sandwich, the total amount of beef is generous, but each individual patty stays thin enough to get deeply browned before the interior overcooks. Season both sides with your favorite burger seasoning before they hit the griddle.

Cheese on the Patty, Cheese on the Bun

American Cheese for the Melt Factor

American cheese goes on each patty while it is still on the griddle, and an additional slice goes on the bottom bun during assembly. The double cheese placement means you have melted cheese bonding the two patties together and another layer of cheese anchoring the bottom patty to the bun. American cheese melts into a smooth, creamy layer that coats the beef without separating or getting greasy, which is exactly what a patty melt needs to hold the stack together.

No Cheese on the Top Bun

The top bun stays cheese-free because the chipotle mayo and pickles go there instead. Stacking cheese on the top bun would make the sandwich too heavy and one-note, while the chipotle mayo adds a creamy, smoky heat and the pickles add acidity and crunch that cut through the richness of the double cheese, bacon, and caramelized onions below.

Assembly and the Final Press

Stack Order Matters

On the inverted bottom bun, layer American cheese first (it melts into the bun during the final press), then chipotle mayo, then both cheesy patties stacked on top, followed by the caramelized onions, pickles, and crispy bacon. Place the inverted top bun on last. The heavy items (patties, cheese) sit at the bottom where they are closest to the heat during the final press, and the lighter items (pickles, bacon) sit higher where they will not get crushed.

Press and Toast Until Golden

Place the assembled patty melt back on the griddle and press lightly with a spatula. The gentle pressure increases the contact between the inverted bun and the griddle surface, which crisps the soft bread into a golden, toasted crust. Cook until the bottom bun is golden brown, then flip carefully and toast the other side. This final press step melts the cheese between the patties, warms everything through, and gives both bun surfaces that crispy, diner-style texture that makes this a patty melt instead of just a stacked burger.

Step-by-Step: How to Make a Bacon Cheeseburger Patty Melt

Step 1: Cook the Bacon

Lay bacon strips on the griddle and cook until crispy. Remove and set aside on a paper towel-lined plate, but leave the rendered bacon fat on the griddle for the onions.

Step 2: Caramelize the Onions in Bacon Fat

Add the sliced sweet onion directly into the bacon fat on the griddle. Cook over medium heat, stirring occasionally, until the onions are soft, golden, and caramelized, about 8 to 10 minutes. Remove and set aside.

Step 3: Cook the Patties

Form the 80/20 ground beef into thin patties and season both sides with your favorite burger seasoning. Cook on the hot griddle until the bottom is deeply browned with a crispy crust, then top each patty with American cheese, flip, and let the cheese melt before removing.

Step 4: Invert and Build

Flip the brioche buns inside out so the soft interior side faces outward. On the inverted bottom bun, layer American cheese, chipotle mayo, two cheesy burger patties, caramelized onions, pickles, and crispy bacon. Place the inverted top bun on last with no cheese on it.

Step 5: Press and Toast on the Griddle

Place the assembled patty melt back on the griddle and press lightly with a spatula until the inverted bun surfaces are golden brown and crispy on both sides. The gentle pressing increases contact with the griddle, melts the cheese between layers, and gives the sandwich that diner-style toasted exterior. Serve immediately.
