I really like Green Bean Casserole, but it's usually only made during the holidays and I've only had the variation that's baked in the oven. I found a recipe in the Fix-It and Forget-It Slow Cooker Magic Cookbook and thought I'd give that version a try. Turned out pretty tasty, if I do say so myself.
2 Tbsp. butter
1 Tbsp. flour
1 tsp. sugar
2 lbs. frozen green beans, cooked and drained
1 cup sour cream
1/2 cup shredded cheddar cheese
1 cup French fried onion rings
In a saucepan, melt butter. Whisk in flour until smooth. Add sugar and sour cream. Stir over low heat until thick and hot.
Combine green beans with sour cream sauce. Place in slow cooker.
Sprinkle green bean mixture with cheese and onions rings.
Cover and cook on low for 2-3 hours.
