Holiday Green Bean & Portabella Mushroom Casserole

Trader Joe’s

1 ½ tablespoons butter

1 ½ tablespoons olive oil

1 bag sliced crimini portabella mushrooms

¼ sweet onion sliced

24 ounces green beans

1 container cream of portabella mushroom soup

½ cup water

1 ½ cup Swiss cheese, shredded

½ can fried onion pieces

Preheat oven to 375F. Heat olive oil and butter in a large heavy skillet; add mushrooms and saute until they become soft and lightly browned. Add onion and continue to saute until soft and lightly browned. 

I went with big ol' hunks of mushrooms, because I friggin' love mushrooms.

Add green beans and saute until heated through. 

Canned green beans, because that's how you make green bean casserole in my world. 

Add soup and water to skillet, mix and heat through. Add mixture to a small or medium size casserole. Top with cheese. 

What a great addition!

Top cheese with fried onions pieces; place in the oven and bake until cheese melts and becomes warm and bubbly, about 15 to 20 minutes.

Golden and delicious.

My Rating: 4/5 "This is without a doubt the most delicious green bean casserole I have ever made. The addition of the mushrooms and Swiss cheese was epic. I could have handled fewer french-fried onions, but that's only a minor complaint. Save this for your next holiday get-together so you can mix life up a little."
