In a small saucepan over medium-low heat, combine ½ cup of heavy cream with 3 minced garlic cloves. Stir continuously for about 5 minutes until the cream begins to warm and the garlic becomes fragrant. Gently whisk in ⅓ cup of mayonnaise, then season with salt and pepper to taste. Remove from heat and set aside to allow the flavors to meld.

In a large bowl, gently mix 1 pound of ground beef with the remaining minced garlic cloves, 1 teaspoon of garlic powder, salt, and pepper. Be careful not to overwork the meat to maintain tenderness. Shape the mixture into 4 equal patties, making a slight indent in the center of each to promote even cooking.

Preheat a skillet or grill pan over medium-high heat, adding a drizzle of oil if desired. Once hot, place the patties in the skillet and cook them for 4-5 minutes per side, or until they reach your preferred level of doneness. Look for a nice brown crust on the exterior and juices running clear to ensure they’re cooked through. Remove the patties from heat and let them rest for about 2 minutes.

While the patties rest, slice the brioche buns in half and melt 2 tablespoons of butter in the same skillet over medium heat. Place the cut sides of the buns down in the skillet and toast until golden brown, about 1-2 minutes. Keep an eye on them to avoid burning, as a perfectly toasted bun adds wonderful texture and flavor to your Garlic Overload Burgers.

Now it's time to build your Garlic Overload Burgers! Start by laying down a handful of fresh arugula on the bottom half of the toasted bun. Place one beef patty on top, then generously drizzle the creamy garlic sauce over the patty. Crown it with the top half of the bun and prepare for a delightful flavor explosion that’s sure to impress!
