Favorite Green Bean Casserole

Here's a recipe I discovered on Trader Joe's Gourmet Fried Onion Pieces container. I made some adjustments and put it together for our Thanksgiving feast yesterday - it was delicious!

This is my version of the recipe:

2-3 lbs of fresh green beans (pressure cook and set aside, cooks in less than 5 minutes!)
6 Tbsp unsalted butter
1 medium white onion, finely diced
1 tub mushrooms chopped up
2 tsp salt
1/2 tsp freshly ground pepper
1/4 cup flour
2 cups milk
8 oz Trader Joe's Fried Onion Pieces

Step 1: Onions and Mushrooms
In large skillet over medium heat, melt 2 Tbsp butter.
Add onions and saute about 4 minutes.
Add mushrooms cook about 6 minutes or until soft.
Season with 1 tsp salt and 1/4 tsp pepper. Set aside to cool.

Step 2: White Sauce
Melt 4 Tbsp butter in medium saucepan over medium to high heat.
Add 1/4 cup flour, whisk until mixture begins to turn golden about 2 minutes.
Pour in milk and whisk constantly until mixture thickens about 3 minutes.
Stir in 1 tsp salt and 1/4 tsp pepper.
Remove from heat to cool.

Step 3
Mix together mushrooms and onions with White sauce
Butter a 9" X 13" glass or ceramic baking dish.
Spread green beans in dish, pour white sauce mix over it.
Cover dish with foil.
Broil about 10 -15 minutes until heated through.
Remove from oven and sprinkle Trader Joe's Gourmet Fried Onion Pieces on top of green beans. Serve immediately.

Notes: You can save time and use a can of cream of mushroom, however after trying this mushroom sauce I will not be using the can stuff anymore! Homemade is best! If you are not planning on serving this dish right away - do not put the fried onions on they will get soggy! Leave the beans covered in a warm oven and sprinkle on the fried onions right before serving.
This mushroom white sauce would be great over linguine or fettuccine any pasta for that matter! This is a tasty white sauce recipe to keep on hand if you are out of cream of mushroom in your food storage or need a quick white sauce for a dish. Melt some cheese with the white sauce for a cheesy sauce!
