Start by cooking the bacon with your favorite cooking method. Once the bacon is cooked allow it to cool and then cut into small bits. Set aside.

In a large skillet, over medium heat, melt the butter. Add the onion and mushrooms.

Saute until the onions have softened and the mushrooms are lightly browned. Once they are cooked set aside.

In a large bowl place the ground beef. Add the salt, garlic, black pepper, oregano, half of the onion/mushroom mixture and half of the bacon bits. Mix well. Form into patties.

Place the burgers in the skillet and cook over a medium heat. Cook until the internal temperature if 160 F. Then remove from the skillet.

Once the burgers have been removed from the skillet leave the heat on medium. Slowly pour the beef broth in the skillet while gently whisking to help loosen the tasty bits stuck on the pan.

Once all the bits have been loosened add in the Worcestershire sauce and liquid smoke (if using this). Mix well.

Add the cream in slowly while gently whisking the mixture. Add in the Parmesan cheese and whisk until combined.

Once the cream has been added in then stir in the remaining onion/mushroom mixture.

Add salt and pepper to taste.

Add the burgers back into the sauce and cook over a low heat for about 5 minutes. This lets all the flavors mix together.

Before serving sprinkle the remaining bacon bits over the burgers.
