This is my go-to burger recipe. It came from a Weber's Real Grilling cookbook I got decades ago.
1 1/2 pounds ground beef
1 T Ketchup
1 t. dried basil
1/2 t. dried thyme
1/2 t. kosher salt
1/2 t. Worcestershire sauce
1/2 t. Tabasco sauce (I skip this now because of the kids)
1/4 t. freshly ground black pepper
Mix everything together well in a bowl. Portion out the burgers into 1/4-1/3 pound portions and flatten. Grill over direct high heat 8-10 minutes, turning once. This will be about Medium, so longer if you prefer them more well-done.
