1. Make the Compound Butter:

Start by preparing the garlic compound butter, which is essential to the flavor of this burger. In a medium bowl, combine the softened unsalted butter, minced garlic, chopped parsley, salt, and black pepper. Mix well until all ingredients are thoroughly combined. Once done, transfer the mixture onto a sheet of plastic wrap, roll it into a log shape, and refrigerate for at least 30 minutes until it firms up.

3. Make the Garlic Aioli:

Next, prepare the garlic aioli that will add a creamy richness to your burger. In a small bowl, whisk together the mayonnaise, minced garlic, fresh lemon juice, salt, and pepper until smooth. Once done, cover the aioli and refrigerate it until you’re ready to assemble the burgers.

5. Form the Patties:

In a large bowl, combine the ground beef, Worcestershire sauce, garlic powder, onion powder, kosher salt, and black pepper. Gently mix together with your hands until just combined—avoid overmixing to keep the patties tender. Divide the meat mixture into four equal portions and shape each portion into a patty that is slightly wider than your brioche buns, pressing a shallow dimple in the center of each; this helps prevent puffing as they cook.

7. Cook the Burgers:

Preheat a cast-iron skillet or grill to medium-high heat. Once hot, add the burger patties and cook for about 3 to 4 minutes per side for medium doneness. In the last minute of cooking, place a slice of cheese on each patty and cover with a lid to melt the cheese fully.

9. Toast the Buns:

While your patties are cooking, take your cold garlic compound butter out of the refrigerator. Slice off a round of the butter and melt it in the skillet after you remove the cooked patties. Dip the cut sides of the brioche buns into the melted garlic butter, then place them cut side down in the skillet, toasting for about 1 to 2 minutes until they develop a deep golden color.

11. Assemble the Burgers:

Now comes the fun part—assembling your mouthwatering Garlic Butter Beef Cheeseburger! Start by generously spreading the garlic aioli on both sides of the toasted brioche buns. Place the melted cheese-topped patties on the bottom half of each bun. Layer with crisp lettuce, slices of fresh tomato, thinly sliced red onion, pickles, and bacon, if desired.

13. Finish and Serve:

As a final touch, slice another round of the chilled garlic compound butter and place it directly on top of the hot patty just before adding the top bun. This will allow the butter to melt into the meat, enhancing the flavor. Serve your Garlic Butter Beef Cheeseburgers immediately while they’re warm and juicy.
