Setup & Equipment

• Grill or stovetop skillet – for cooking the patties evenly with a nice sear

Caramelized Onion Swiss Burgers Cooking Guide

Step 1: Mix the Patty Ingredients

In a large bowl, gently combine the ground beef with Worcestershire sauce, Montreal Steak Seasoning, and crushed garlic. Be careful not to overwork the meat to keep the patties tender. Divide the mixture into four equal portions and shape each into a round patty about ¾-inch thick.

Step 2: Prepare the Cooking Surface

Heat your grill or skillet over medium-high heat. Lightly oil the surface to prevent sticking. If you’re using a grill, make sure the grates are clean and hot for that perfect sear.

Step 3: Cook the Patties

Place the patties on the hot surface. Cook for about 4 minutes on one side without moving them to develop a crust. Flip carefully and cook for another 3 minutes.

Step 4: Add Swiss Cheese and Caramelized Onions

When the patties are almost done, place a slice of Swiss cheese on each one and cover the grill or pan briefly to allow the cheese to melt. Once the cheese is melted, top each patty with about 2 tablespoons of caramelized onions.

Step 5: Toast the Buns

While the cheese melts, slice and lightly toast your hamburger buns on the grill or in a toaster to add a slight crunch and warmth.

Step 6: Assemble and Serve

Place each patty on the bottom half of a bun, then add any additional toppings you love, followed by the top bun. Serve immediately while warm. For a perfect side, try pairing these burgers with Buttered Red Potatoes With Dill for a comforting, flavorful meal.

Allergy-Friendly Swaps

• Ground beef: Substitute with ground turkey or chicken for a leaner option.
• Swiss cheese: Use a dairy-free cheese alternative or omit cheese entirely.
• Hamburger buns: Replace with gluten-free buns or large lettuce leaves for a low-carb alternative.
• Worcestershire sauce: Use soy sauce or tamari for a similar umami flavor, ensuring it’s free from anchovies if needed.

Little Things that Matter

• Don’t press down on the patties while cooking; it squeezes out the juices and dries the meat.
• Let the burgers rest for a couple of minutes after cooking to allow juices to redistribute.
• Use a thermometer to check for doneness—160°F is the safe internal temperature for ground beef.
• Caramelizing onions takes patience but adds incredible depth; check out the linked caramelized onions recipe for tips on perfect results.
• Customize toppings to your liking—crispy bacon, fresh lettuce, and ripe tomato all pair wonderfully.

Prep Ahead & Store

You can prepare the caramelized onions a day or two in advance and store them in the refrigerator. The beef patties can also be shaped ahead of time and kept covered in the fridge for a few hours before cooking. Leftover burgers are best eaten the same day but can be refrigerated in an airtight container for up to 2 days. To reheat, warm gently on the stovetop or in the oven to retain juiciness without overcooking.

Caramelized Onion Swiss Burgers Q&A

Can I use a different type of cheese?

Absolutely! While Swiss cheese complements the caramelized onions beautifully, you can substitute with provolone, Gruyère, or even a sharp cheddar to match your preference. Each brings a unique flavor profile that enhances the burger.

What if I don’t have Montreal Steak Seasoning?

No worries! You can create a simple seasoning mix using salt, black pepper, garlic powder, onion powder, and a hint of smoked paprika. This DIY blend will work well to flavor your patties while keeping things straightforward.

How do I get the caramelized onions just right?

Patience is key! Slowly cooking onions over low to medium heat with a little oil or butter allows their natural sugars to develop and turn golden brown. Stir occasionally and don’t rush the process with high heat to avoid burning.

Can I cook these burgers indoors if I don’t have a grill?

Definitely! A cast-iron skillet or heavy-bottomed pan on your stovetop works perfectly. Heat the pan well, add a little oil, and follow the same cooking times to achieve a flavorful crust and juicy center.

Serve with These

• Buttered Red Potatoes With Dill – a creamy, herbaceous side that complements the savory burgers
• Perfect Grilled Steak – if you’re cooking for a crowd, add this for a steakhouse-style meal
• Raising Canes Sauce – a tangy, creamy dip that pairs beautifully with fries or burger toppings
