Gunnar and Ravens Burgundy Sauce Recipe

  • 1 tablespoon butter
  • 1 tablespoon olive oil
  • 2/3 cup chopped onion
  • 2 cloves garlic, chopped
  • 2 tablespoons all-purpose flour
  • 2/3 cup beef broth
  • 1 cup Burgundy wine
  • 1 pinch dried basil, or to taste
  • 1 pinch dried oregano, or to taste
  • 1 1/2 cups sliced baby portobello mushrooms
  1. Heat butter and olive oil in a large skillet over low heat; cook and stir onion and garlic in the hot butter-oil mixture until onion is transparent, 5 to 10 minutes. Add flour and slowly pour in beef broth while stirring constantly until flour is smoothly mixed into the broth and vegetables.
  2. Stir Burgundy wine into onion-flour mixture; season with basil and oregano. Bring mixture to a simmer; add mushrooms. Cook and stir until sauce is thickened, about 10 minutes.
