Ingredients

Garlic Soy Sauce

  • ¼ cup butter, salted, 4 tablespoons
  • 1 tablespoon garlic, minced about 2-3 cloves.
  • 24 ounces baby bella mushrooms, wash, dry and slice
  • 2.5 tablespoons AP flour, all purpose flour
  • ¾ - 1 cup 2% milk
  • ½ cup chicken broth, if the sauce gets too thick simply add a touch more broth.
  • 1.5 tablespoons low sodium soy sauce
  • 24 ounces fresh green beans , rinse and dry the beans. remove the stems. Cut them in half if they are long.
  • salt, to taste
  • black pepper , to taste
  • ½ cup crispy fried onions

Equipment

  • 1 large oven safe pan
  • 1 9x13 inch baking dish

Instructions 

  • Preheat the oven to 350 degrees. Grab a large oven safe pan and place it over medium high heat. Add butter, sliced mushrooms and minced garlic. The mushrooms will soften and brown, releasing some moisture.
  • Once slightly browned, dust the mushrooms with the AP flour, salt and pepper. Stir well. The flour will soak up some of the moisture.
    Reduce the heat to medium.
    Next, slowly add the milk. As you add the milk, a creamy sauce will begin to form. Once all the milk is added, repeat the same process for the chicken broth. If the sauce gets too thick, simply add a touch more broth and make sure you reduced the heat to medium low.
  • Once the chicken broth is well incorporated, add the low sodium soy sauce. Stir until well combined.
  • Next, you will add the rinsed and dried green beans.
    NOTE: you have the option to blanch the green beans in a separate pot of boiling water to soften them. See above for instructions. I prefer a slight crunch so I skip this step.
  • Simmer everything together in the pan for 5 minutes if you blanched the green beans and 10 minutes if you did NOT.
    NOTE: you have the option to add everything to a 9x13-inch baking dish that has been sprayed with cooking spray. Or you can leave it in the oven safe pan. See above for details.
  • Next, you will sprinkle crispy fried onions over the top of the dish. Cover the dish with foil and bake it for 20 minutes at 350 degrees. Remove the foil and bake for an additional 5 minutes.
  • Remove from the oven and serve warm.
