Small chef in small restaurant always looking for good side dishes. I usually shy from "soup' ingredients but follwed through with a few good changes. I began with half the butter in which I sauted 1 shallot, minced, and the 4 cloves of crushed garlic (fresh). I then added the 1 tbs of flour and let it cook slightly. I then added the can of soup, let it thicken and then thinned it a bit with 1/4 to 1/2 chicken stock. I the chopped 2 bags of baby spinach, about an inch or so thick and after the heat is off folded it gently into the sauce mixture. I did not let it cook. Placed it all in a 9X13 buttered dish - topped it with 1 cup Panko crumbs, seasoned with S&P and a little Olive oil. I baked it for 15-20 min just to bring it to heat and crisp the topping. Rave reviews...Please try it with the fresh spinach and you will never go back to frozen.

Not that good to me: very bland compared to normal creamed spinach. I used fresh spinach and garlic (why wouldn't you?).tried "as is" and then added some italian seasoning and red pepper flakes in attept to fix. Still blah. Also~ canned soup is extremely salty! Don't add extra salt before tasting!!!

My husband and I really liked this dish. I used cream of mushroom soup instead of celery. I also melted only half the butter and cooked the onion in it before adding the other ingredients. I don't like raw onions which I think these would have been because the dish comes together so quickly. I don't think cutting down on the butter hurt it one bit. I will certainly make this again.

This recipe was quick and easy. I had recently visited a farm market and purchased a large quantity of fresh spinach, which I blanched and chopped. Had on hand cream of mushroom instead of celery soup. Sauted the onions in just 2 T. of butter instead of 4, omitted adding any additonal salt and used 1/2 Tsp. powdered garlic. It was scrumptous! My husband suggested trying it next time not sauting the onions for the added crunch. This man hates creamed spinached, but gobbled this down and said I should definitely make it again.

Very good, but it's more like a dip or a variation of creamed spinach. You really don't need butter and flour, the cream soup makes it thick enough. I ended up adding some milk to thin it out a bit. I also substituted with scallions and cream of mushroom soup.

Another keeper!!! Followed recipe exactly and it was on the mark. I had put this in my shopping list so I did have Cream of Celery on hand and I wouldn't change that - I'm sure it gave the spinach more flavor than using Cream of Mushroom. I thawed my spinach very early in the day and three times during the day I put the spinach in a paper towel and squeezed out the water. It was a great consistancy when I was ready to cook it. Thanks sumbitter.

Great dish. I used fresh baby spinach, added fresh mushrooms and garlic. I sauted the onions, musrooms and garlic before adding the soup, flour, and chopped spinach. I then added panko bread crumbs and baked for 20 minutes at 375, then topped with parmigiano cheese just before serving.

This side dish is deeelicious!! I saute the chopped onions in olive or butter for 5 minutes first. There is no need to add the flour or additional salt. Second of all, I used Campbell's cream of chicken/mushroom soup. Third of all, make sure your spinach is squeezed DRY (as dry as possible). I do it by hand over a colander. You can add 1 Tbsp of milk or so if it is too thick. This is one of my favorite side dishes. Thank you Stephanie!!
