From the ground chicken’s succulence to the sweet depth of caramelized onions and the creamy melt of white cheddar, each piece comes together to create pure burger bliss.

- Salt (1 teaspoon): Essential for seasoning both the chicken patties and bringing out every other flavor.

- Large Onions, thinly sliced (2): Slowly cooked until golden and sweet, they’re the ultimate burger topper.
- Butter (2 tablespoons): Adds richness to the onions, making them gorgeously glossy and flavorful.
- Brown Sugar (1 teaspoon): Speeds up caramelization and enhances the onions’ natural sweetness.

How to Make Chicken Burgers with Caramelized Onions
Step 1: Caramelize the Onions
Start by heating olive oil in a large skillet over medium heat. Toss in those thinly sliced onions and let them cook low and slow, stirring often. Patience is key here—about 20 minutes will take those onions from sharp and firm to soft, sweet, and jammy. Once golden brown, add the butter and brown sugar to really amp up the flavor, and continue cooking for another 5 minutes to achieve perfect caramelization. Set the onions aside while you get the patties ready.
Step 2: Prepare the Chicken Patties
In a large bowl, gently mix the ground chicken with garlic powder, onion powder, smoked paprika, salt, and black pepper. Don’t overwork the mixture—just blend everything until it’s cohesive, then form it into four evenly sized patties. This keeps the burgers tender and juicy instead of dense or tough.
Step 3: Grill or Pan-Cook the Patties
Heat a grill pan or skillet over medium-high heat. Add the chicken patties and cook for about 5 to 6 minutes on each side. You’re looking for that golden crust outside and a juicy, fully cooked interior—make sure the internal temperature hits 165°F (74°C). For maximum deliciousness, lay a slice of white cheddar over each patty in the last minute of cooking and cover the pan until the cheese is gloriously melted.
Step 4: Toast the Buns and Prep the Toppings
While your patties are cooking, lightly toast your brioche buns either on the grill or in a dry skillet. Toasting not only boosts the flavor, but also helps keep the buns from getting soggy once you pile everything on. Get your lettuce, tomato slices, and condiments ready for assembly.
Step 5: Assemble the Chicken Burgers with Caramelized Onions
Time for the fun part! Spread a generous layer of mayonnaise or aioli onto both the top and bottom halves of your toasted buns. Place a lettuce leaf and tomato slice on the bottom bun, top with the cheesy chicken patty, then add a heaping spoonful of your beautifully caramelized onions. Crown it with the other half of the bun and serve immediately while it’s warm and melty.
How to Serve Chicken Burgers with Caramelized Onions

Garnishes
Dress your Chicken Burgers with Caramelized Onions with even more flavor by adding a sprinkle of fresh chives or parsley on top of the onions. A little extra cracked black pepper or a touch of sriracha on the bun gives just the right pop of color and zing. For an extra fancy touch, try a tiny drizzle of aged balsamic!
Side Dishes
These burgers play well with nearly any side, but crispy baked sweet potato fries, a colorful slaw, or garlicky roasted potatoes are unbeatable classics. For something fresher, serve with a simple green salad dressed with lemon vinaigrette, or homemade pickles to cut through the richness of the chicken and cheese.
Creative Ways to Present
Impress your guests by stacking sliders instead of full-size burgers for effortless party bites, or serve open-faced with a salad to keep things lighter. If you’re feeling adventurous, swap out the brioche buns for pretzel rolls, ciabatta, or even wrap everything in crisp lettuce leaves for a gluten-free twist on Chicken Burgers with Caramelized Onions.
Make Ahead and Storage
Storing Leftovers
If you have leftover Chicken Burgers with Caramelized Onions, let them cool to room temperature before packing them into airtight containers. Separate the components if possible, so the buns and toppings don’t get soggy. Stored this way, they’ll keep fresh in the refrigerator for up to 3 days, making them just as delicious for a quick lunch or dinner.
Freezing
Chicken patties can be frozen for up to three months—just wrap them tightly in plastic wrap or foil and store in a freezer-safe bag. For the best texture, freeze the patties alone and prepare the toppings fresh when you’re ready to eat. Caramelized onions themselves freeze well too; portion them into small containers for an easy burger upgrade anytime.
Reheating
To keep your Chicken Burgers with Caramelized Onions moist and flavorful, reheat patties in a covered skillet over low heat, adding a splash of water or broth to prevent drying out. Onions can be gently warmed in a pan or microwave. Assemble everything fresh for that just-cooked taste and texture.
FAQs
Can I use ground turkey instead of chicken?
Absolutely! Ground turkey makes a great substitute for chicken in this recipe, providing a very similar taste and juiciness. Just make sure to watch the cooking time closely, as turkey can dry out if overcooked.
What’s the secret to perfect caramelized onions?
Patience is everything! Cook the onions low and slow, stirring often. Don’t rush the process or crank up the heat, or you’ll end up with burnt onions instead of that rich, jammy sweetness that makes Chicken Burgers with Caramelized Onions so special.
Can I make the burgers ahead of time?
Yes, you can prep the patties and caramelize the onions ahead and keep them refrigerated separately until ready to cook and assemble. This makes Chicken Burgers with Caramelized Onions a perfect choice for easy entertaining or busy weeknights.
Is there a dairy-free way to enjoy this burger?
Of course! You can skip the cheese or opt for your favorite dairy-free cheddar-style slices. Use a plant-based mayo or aioli for serving if needed—the flavors of the caramelized onions and spiced chicken will still shine through.
How do I know when the chicken patties are cooked through?
A meat thermometer is your best friend; the internal temperature should reach 165°F (74°C). The patties should be golden brown outside and no longer pink inside, but still juicy.
