Equipment

  • stove
  • oven

Ingredients
  

  • 8 ounces Bella mushrooms finely chopped*
  • 1 small onion finely chopped*
  • 1-2 Tbsp vegan butter or oil optional
  • 4 garlic cloves minced (2 Tbsp)
  • 2 pounds green beans trimmed (fresh or frozen)
  • 3 Tbsp flour**
  • 1 cup vegetable broth or water
  • 1 cup plant milk
  • 1 tsp vegan worcestershire sauce
  • ½ cup vegan parmesan cheese shredded
  • 6 ounces crispy fried onions divided
  • salt and pepper to taste optional

Instructions
 

  • Preheat the oven to 375° F.
  • In a large skillet or pot, sauté the mushrooms and onions with the vegan butter or oil over medium heat for about 4-5 minutes. If not using butter or oil, add a tablespoon of water or vegetable broth, as needed, to keep the onions and mushrooms from sticking.
  • Stir in the green beans and garlic. Sauté 10-12 minutes, stirring occasionally. The green beans should be tender. This may take an extra few minutes if your green beans are frozen.
  • Stir in the flour until everything is evenly coated, about a minute. Then slowly stir in the broth until a smooth thick gravy forms.
  • Slowly stir in the milk, a little at a time, until the milk is absorbed by the gravy. Continue to simmer, stirring occasionally, until the sauce is thick and bubbly, about 4-5 minutes.
  • Remove from heat. Stir in the Worcestershire sauce, vegan parmesan, and 1 cup fried onions. Taste and adjust the garlic, salt and pepper, if desired.
  • Pour the green bean mixture into a large casserole dish.
  • Spread the remaining fried onions evenly over the top.
  • Bake for 20-25 minutes, until the top is nice and golden.

Notes

* I use a food processor to speed up the dicing/chopping process.
** Use any flour you have on hand, including gluten-free baking blend.  I typically use white whole wheat.
