Wisconsin Butter-Basted Burgers PT30M https://img3.recipesrun.com/201907/2019/0821/46/f/473158/300x200x90.jpg It's no secret Wisconsinites love their dairy—in fact, they love it so much they top their burgers with a generous pat of butter. My recipe is a lot like the butter burgers you'll find in popular restaurants all over the state. The mushrooms and butter basting add great flavor to this burger. These were a hit with my family. 4 servings Ingredients: Mustard Ketchup Dill pickle slices Lettuce leaves Tomato slices 4 Hamburger buns, split 3 tbsp. Butter, divided 1/2 pound Fresh mushrooms 1/2 tsp. Pepper 1/2 tsp. Seasoned salt 1 pound Lean ground beef (90% lean)
