This cheddar cheeseburger is proof that sometimes the simplest recipes are the best. I used all my husband’s favorite ingredients (garlic bread, all-beef burger patties, Cheddar cheese, and caramelized onions) to create this flavorful, no-frills burger — and it’s delicious.
Heat the butter and olive oil in a sauté pan. Add the onions along with a pinch of salt and the pinch of sugar. Cook the onions on low heat until soft and browned, about 20 - 30 minutes. Set aside.
Heat your grill or cast-iron grill pan to medium-high heat.
Cut the loaf of French bread into 4 equal pieces and then slice each piece lengthwise. Drizzle the cut side of the French bread with olive oil and then grill cut-side-down until toasty and slightly charred. Then, cut each clove of garlic in half. Rub the cut side of the garlic onto the surface of the grilled French bread a few times so that the bread absorbs the flavor of the garlic. Set the bread aside.
Divide the ground beef into four equal pieces and gently form each into a burger patty. Season well with salt and pepper and then brush each patty lightly on both sides with oil. Grill the burger patties to the desired degree of doneness, about 4-6 minutes per side.
Then, top each burger patty with a slice of cheese and grill one minute more to melt the cheese.
Serve the burgers on the garlic bread, topped with caramelized onions.
