Ingredients
- 1/2 Tbsp. avocado oil
- 1/2 yellow onion chopped
- 2 cloves garlic minced
- 1 lb. fresh green beans trimmed & cut in 1/2-in pieces
- 4 oz. baby bella mushrooms sliced
- 1-1/2 Tbsp. all-purpose flour
- 1 cup vegetable broth
- 1/4 cup oat milk unsweetened
- 1/2 tsp. soy sauce or tamari
- 1/4 tsp. Himalayan fine pink salt
- 1/8 tsp. black pepper
- 3 Tbsp. nutritional yeast
- 3/4 cup vegan fried onions divided
- 3 packages of phyllo dough cups
Instructions
-
Preheat oven to 350 degrees F.
-
In large skillet over medium heat, add olive oil. Add chopped onion and cook until softened, about 5 minutes. Add minced garlic and cook another minute until fragrant.
-
Add trimmed green beans and sliced mushrooms to skillet. Cook, stirring occasionally, until green beans are tender-crisp and mushrooms are softened, about 8-10 minutes.
-
Sprinkle all-purpose flour over green bean mixture and stir well to coat everything evenly. Cook 1 minute, stirring constantly.
-
Gradually pour in vegetable broth and plant-based milk, stirring constantly to prevent lumps from forming. Bring mixture to simmer and cook until sauce has thickened, about 3-5 minutes.
-
Stir in soy sauce, salt, black pepper and nutritional yeast. Taste and adjust seasonings as needed.
-
Remove skillet from heat and stir in 1/2 cup vegan fried onions, reserving remaining 1/4 cup for topping.
-
Place phyllo dough cups on a baking sheet.
-
Spoon green bean mixture into phyllo dough cups, filling each cup to the top.
-
Sprinkle remaining 1/4 cup vegan fried onions over top of the filled phyllo cups.
-
Bake in preheated oven 10-15 minutes, or until the phyllo cups are golden brown and filling is heated through.
-
Remove from oven and let cool a few minutes before serving.
