What You’ll Need to Make This Recipe
Ground beef with a moderate amount of fat works best for juicy burgers. An 80/20 blend is especially good because the fat keeps the patties flavorful while they cook.
Cheddar cheese melts over the hot patties and gives the burger its rich, cheesy flavor. American cheese can also be used if you prefer an extra-melty texture.
Yellow onions are slowly cooked in butter and a little oil until soft, golden, and sweet. Do not rush this step because the caramelized onions add a lot of flavor.
Brioche burger buns provide a soft, slightly sweet base for the burger. Toasting the buns keeps them from becoming soggy and adds a delicious buttery crust.
Lettuce, tomato, and pickles add freshness, acidity, and crunch to balance the richness of the beef and cheese.
Burger sauce combines mayonnaise, ketchup, mustard, and pickle juice for a creamy, tangy sauce that works perfectly with the beef.
The exact measurements for all ingredients are listed in the recipe card below.
How to Make This Double Cheeseburger Step by Step
Step 1: Make the Burger Sauce
In a small bowl, combine the mayonnaise, ketchup, yellow mustard, pickle juice, garlic powder, and black pepper.
Stir until smooth and creamy. Taste the sauce and add a little more mustard or pickle juice if you prefer a tangier flavor.
Cover and refrigerate the sauce while you prepare the rest of the burger.
Step 2: Caramelize the Onions
Thinly slice the onion. Heat the butter and olive oil in a large skillet over medium-low heat.
Add the sliced onions and a small pinch of salt. Cook slowly for about 15 to 20 minutes, stirring occasionally, until the onions become soft, golden brown, and deeply caramelized.
If the onions begin to brown too quickly, reduce the heat. You want them soft and sweet rather than burnt.
Step 3: Prepare the Beef Patties
Divide the ground beef into four equal portions. Gently shape each portion into a thin patty slightly wider than the burger buns.
Season both sides with salt, black pepper, garlic powder, and a little paprika just before cooking.
Do not overwork the beef when shaping the patties. Handling the meat too much can make the finished burgers dense instead of tender.
Step 4: Toast the Buns
Slice the brioche buns in half and lightly butter the cut sides.
Place them cut-side down in a skillet over medium heat and toast for 1 to 2 minutes, until golden and lightly crisp.
Remove the buns and set them aside while you cook the patties.
Step 5: Cook the Burger Patties
Heat a large skillet or griddle over medium-high heat. Add the beef patties and cook for about 2 to 3 minutes on the first side, depending on thickness.
Flip the patties and immediately place a slice of cheddar cheese on each one.
Continue cooking until the beef reaches your preferred doneness and the cheese is completely melted.
Step 6: Build the Burger
Spread a generous layer of burger sauce over the bottom toasted bun.
Add fresh lettuce and a slice of tomato, followed by the first cheeseburger patty.
Place the second cheeseburger patty on top, then add a generous spoonful of caramelized onions.
Finish with sliced pickles and another layer of burger sauce before placing the toasted top bun over everything.
Step 7: Serve
Serve the burger immediately while the beef is hot and the cheese is still melted.
For the best experience, serve it with crispy French fries, potato wedges, onion rings, or a simple side salad.
Expert Tips
- Use 80/20 ground beef: The extra fat helps keep the patties juicy and flavorful.
- Do not overwork the beef: Gently shape the patties for a tender texture.
- Make thin patties: Thin patties cook quickly and are perfect for a double cheeseburger.
- Season just before cooking: This helps keep the patties tender and flavorful.
- Do not rush the onions: Low and slow cooking gives them their deep caramelized flavor.
- Toast the buns: A toasted bun adds flavor and prevents the sauce and burger juices from making the bread soggy.
- Add cheese immediately after flipping: The heat from the second side helps the cheese melt perfectly.
- Use fresh pickles: Their acidity balances the richness of the beef, cheese, and sauce.
- Serve immediately: Burgers are best enjoyed while the patties and cheese are hot.
How to Store and Reheat It
For the best texture, store the cooked beef patties, caramelized onions, sauce, and toppings separately rather than storing the fully assembled burger.
Place leftover patties in an airtight container and refrigerate for up to 3 days. Store the caramelized onions and burger sauce separately in the refrigerator.
To reheat the patties, place them in a skillet over medium-low heat until warmed through. Add a little cheese during reheating if desired.
Toast the buns again before assembling the burger. This helps bring back their soft center and lightly crisp edges.
What to Serve With This Double Cheeseburger
This burger is hearty enough to be a complete meal, but classic sides make it even better.
- Crispy French fries
- Garlic herb potato wedges
- Onion rings
- Sweet potato fries
- Coleslaw
- Pickles
- Simple green salad
- Loaded fries
A cold, crunchy side salad or tangy coleslaw is especially good because the fresh vegetables help balance the richness of the double cheeseburger.
Frequently Asked Questions
What type of beef is best for burgers?
An 80/20 ground beef blend is an excellent choice because the fat provides moisture and flavor. Leaner beef can be used, but the burgers may not be quite as juicy.
Can I use a different type of cheese?
Yes. American cheese, Monterey Jack, pepper Jack, Swiss, or provolone can all be used. Choose a cheese that melts easily for the best result.
Can I make the caramelized onions ahead of time?
Absolutely. Caramelized onions can be prepared ahead and stored in the refrigerator for several days. Warm them gently before adding them to the burgers.
Can I cook the burgers on a grill?
Yes. A grill works very well. Cook the patties over medium-high heat until browned and cooked to your preferred doneness, adding the cheese during the final minute or two.
How do I keep the burger from falling apart?
Toast the buns well, avoid adding too much sauce, and place the heavier ingredients toward the bottom. Using thin patties also makes the burger easier to stack and eat.
Can I add bacon?
Definitely. Crispy bacon is an excellent addition and pairs especially well with cheddar cheese and caramelized onions.
Can I make this burger spicy?
Yes. Add sliced jalapeños, hot sauce, spicy pickles, or pepper Jack cheese. You can also add cayenne pepper to the burger sauce.
How long do leftover burger patties last?
Cooked beef patties can be refrigerated in an airtight container for up to 3 days. Reheat them gently in a skillet before assembling the burgers.
