Chicken Burgers with Caramelized Onions

Chicken burger with caramelized onions, ham, Swiss cheese, and a sweet/hot mustard! My fiance, Dan, created this delicious burger, so we call it "The Danburger." The flavor is amazing. We serve it with baked sweet potato wedges.

Ingredients

• ½ teaspoon salt
• 1 large egg
• ½ teaspoon ground black pepper
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• ½ green bell pepper, diced
• 1 pound ground chicken
• 4 slices Swiss cheese
• ½ cup olive oil, or as needed
• 1 large sweet onion, sliced
• 2 tablespoons salted butter, softened
• 4 whole wheat hamburger buns
• ½ cup panko bread crumbs, or to taste
• 6 slices deli ham, or more to taste, diced
• 4 tablespoons hot, sweet mustard (such as Inglehoffer®)

Recipe Instructions

Step 1

Coat the bottom of a large cast iron skillet with oil. Turn heat to high and wait until oil is hot but not smoking. Add onions and cook for 1 minute. Reduce heat to low or medium-low. Continue to cook, flipping onions every 8 minutes and adding oil if necessary to keep them moist, until dark and caramelized, 25 to 30 minutes.

Step 2

While the onions are caramelizing, preheat an outdoor grill for medium-high heat and lightly oil the grate.

Step 3

Combine ground chicken, bread crumbs, diced ham, egg, bell pepper, onion powder, garlic powder, salt, and pepper in a large bowl. Mix to combine, being careful not to work the meat too much. Form into 4 patties.

Step 4

Grill on the preheated grill over direct heat until cooked through, 4 to 5 minutes per side, adding a slice of Swiss cheese to each in the last minute. An instant-read thermometer inserted into the center of the burgers should read at least 165 degrees F (74 degrees C).

Step 5

Spread butter on the inside of the hamburger buns and grill, face-down, until toasty, about 3 to 5 seconds.

Step 6

Place the patties with cheese on the bottom buns, top with caramelized onions, spread mustard on the top buns, and serve.
