Wisconsin Butter Burger - Solly's Grille Burger Copycat

If you love butter and you love burgers, then this Solly’s Grille burger copycat recipe will rock your socks off. Take notes because this true to the original “butter burger” is bound to be a party favorite of your family.

Let’s kick things off with the stewed onions that are going to be the main topping for the burger. You will need:

  • 3 Tbsp olive oil
  • 2 medium sweet onions (diced)
  • 2 Tbsp unsalted butter
  • 1/2 Cup dry white wine
  • 1 Cup beef broth
  • Salt & pepper to taste

Heat up the olive oil in a medium pan, and once hot enough, throw the onions in it. Also add the butter and let it melt. You don’t want the onions to caramelize, so keep the heat low.

Once the butter is molten, add the wine, and let it cook for 10 minutes. Then add beef broth, salt and pepper. Let it simmer for 20 minutes with the lid on. Then crank up the heat and bring it up to a boil with the lid off, to reduce out all the remaining liquid. When done, set aside at room temperature.

Time to grill the burger! Use meat that’s more than 90% lean, just because of the amount of butter used in this recipe. Spread some butter or oil on the cooking surface, then throw on the patty with some salt.

Flip the patty when the juices start coming through the top. Now spread some of the onion topping on the top side, then place a slice of American cheese on it.

Give the buns a toast. When ready, spread 1-2 tablespoons of butter on the top bun (told you it was going to be a lot!) and assemble the burger.

Enjoy your Solly’s Grille burger copycat!
