Mushroom Casserole

It's not a pretty picture, but it more than makes up for it in taste!

I'm referring to my baked mushroom casserole.  This is a delicious side for anyone who loves mushrooms as much as I do.  

It is a saucy baked dish that combines mushrooms with sour cream and mustard.  

It’s just as good (better ?) left over.  

Personally, I could make a meal of it, and I know others who think alike!

Mushroom Casserole


2 lbs. fresh button mushrooms, sliced
1/4. c. butter, softened
4 T. flour
1 t. salt
2 t. prepared mustard
¼ t. McCormick’s Seasoned Pepper
1 8 oz. carton sour cream
¼ c. chopped parsley
¼ c. chopped onion

Clean mushrooms with a damp paper towel and slice.  Cream butter, flour, salt, pepper, and mustard.  Add sour cream, parsley and onion. Stir well.

Place half the mushrooms in greased 2 qt. dish.  Top with half of the sour cream mixture, spread evenly.  Repeat layers.

Bake 325 degrees for 1 hour or till well heated and golden.

Allow it to set in a warm place, for 5-10 minutes before serving.
6-8 servings
