About

The CBO, short for Chicken Bacon Onion, is a McDonald’s sandwich from some European menus: a breaded chicken fillet with cheese, bacon, crispy onions, lettuce and an onion sauce on a square bun. The onion comes in three forms, which is what gives the sandwich its name and flavour.

This home version starts with the sauce, so it has time to settle: mayonnaise with finely minced white onion, crushed crispy fried onions, garlic and onion powder and black pepper. The chicken breast is trimmed into a rectangle to match a square sesame bun and coated twice, flour, egg wash, then flour again, for a thick, crunchy crust. It fries at 350°F for five to six minutes a side, to 165°F in the centre, with the cheese laid on while it is still hot. Crisp bacon goes on the chicken, and shredded lettuce and more crispy onions go on the top bun.

Recipe

1
First, whip up the signature CBO sauce so the flavors can marry. In a small bowl, combine the mayo, minced white onion, crushed crispy onions, garlic powder, onion powder, and black pepper. Stir it well and let it chill in the fridge. This sauce is what gives the burger its savory, oniony punch.
2
Prepare the chicken patty. Slice the chicken breast into a rectangular shape to fit your square bun. For the breading, set up two bowls: one with the flour and spices (salt, paprika, garlic powder), and another with the egg beaten with water. Dip the chicken into the flour, then the egg wash, then back into the flour for a thick, crunchy coating.
3
Get the bacon crispy. Fry the bacon strips in a pan over medium heat until they're golden and stiff. Remove them and set them aside on a paper towel. Keep the bacon fat in the pan for extra flavor if you like, or wipe it out for a cleaner fry.
4
Deep fry or shallow fry your breaded chicken patty at 350°F (175°C) for about 5-6 minutes per side until it's deep golden brown and the internal temperature reaches 165°F (74°C). While the chicken is hot, place the cheese slices on top so they start to melt.
5
Toast your square bun until the edges are slightly crispy. Spread a generous amount of the CBO sauce on both the top and bottom bun. This burger is all about the layers, so don't be shy with the sauce.
6
Assemble the CBO: On the bottom bun, place the cheesy chicken patty. Add the crispy bacon strips. On the top bun side, pile on the shredded lettuce and a heavy sprinkle of crispy fried onions. Flip the top onto the bottom and enjoy your homemade masterpiece.
