Ingredients
Scale
Main Ingredients:
- 1 (15-count) package mini filo shells, thawed
- 1 cup chopped frozen green beans, thawed
- 1/4 cup French fried onions, for topping
Filling Ingredients:
- 1/2 cup finely chopped fresh mushrooms
- 1 tablespoon butter, for sauteing
- 1 tablespoon flour, for thickening
- 3/4 – 1 cup heavy cream, for the sauce
Seasoning Ingredients:
- 1/8 cup grated Parmesan cheese, for flavor
- 1 pinch onion powder, for seasoning
- Salt and pepper to taste
Instructions
- Preheat the oven to 350°F and arrange mini filo shells on a clean baking sheet, ensuring they are evenly spaced.
- In a skillet over medium heat, melt butter and sauté mushrooms until they become tender and release their moisture, approximately 5 minutes.
- Sprinkle flour over the mushrooms and cook for 2 minutes, stirring constantly to prevent burning and create a roux-like base.
- Gradually pour heavy cream into the skillet, whisking continuously to create a smooth, creamy sauce without lumps.
- Add chopped green beans and Parmesan cheese to the sauce, stirring until the mixture is well combined and heated through. Adjust cream quantity if needed for desired consistency.
- Season the mixture with onion powder, salt, and pepper, tasting and adjusting flavors to preference.
- Using a spoon, carefully fill each filo shell with the green bean and mushroom mixture, ensuring an even distribution.
- Generously top each filled shell with French fried onions for extra crunch and flavor.
- Bake in the preheated oven for 4-6 minutes, watching carefully until the onions turn golden brown and crispy.
- Remove from oven and serve immediately while warm for optimal taste and texture.
Notes
- Customize Texture Control the sauce’s thickness by adjusting heavy cream gradually, ensuring a smooth, creamy consistency without becoming too runny.
- Vegetarian Swap Replace butter with olive oil and use plant-based Parmesan cheese for a dairy-free version that maintains rich flavor.
- Make-Ahead Prep Cook green bean mixture and store separately from filo shells in the refrigerator, assembling and baking just before serving to preserve crispy texture.
- Dietary Adaptation Use gluten-free flour and check filo shells’ ingredients for guests with gluten sensitivities, making this appetizer inclusive for more dietary needs.
