Pasta Crab Casserole Recipe

Pasta Crab Casserole Recipe

This is an easy dish to freeze ahead for company. A yummy combination of spiral pasta, crab and sauteed veggies is coated with a buttery sauce, then covered with cheddar cheese. All that's needed to complete the meal is a warm garlic bread and a tossed green salad. —Georgia Mountain Tampa, Florida

"This is a very good casserole & quick to make. I've made it several times. I also agree that 2 onions are too much. 1 is plenty."

"I've made this a couple of times and my family likes it. Instead of making 2 casseroles, I just put it in a 9" x 13" dish. I like a traditional mac and cheese, but this is nice for a change."

"I made this recipe almost exactly as written the first time I tried it, only using less onion. Two large onions is WAY too much. As I suspected, 8 ounces of pasta for two casseroles was WAY too little. The second time I used a pound box of pasta. I think it worked much better!! Other than that, my family loves this recipe. The imitation crabmeat often goes on sale buy one get one free around here, so now I always grab it and eagerly look forward to this meal!!"

"This recipe turned out really great! I especially liked the fresh mushrooms in the mix; they added so much flavor. Since I live at a high altitude I doubled the sour cream (fat-free). Will definitely make again."

"My family loves this. I have also made it a few times for company. I find it a real treasure recipe in that part one is made and eaten, and part 2 is frozen and served a few weeks down the road on a busy day. I use no fat sour cream and low fat cheese to cut the fat. Also on rushed days, I go to the salad bar and get chopped onions, peppers, and sliced mushrooms. I sometimes get a mix of red, yellow and green peppers. It makes for a pretty casserole. I recommend at least trying it to see if it fits your taste."

"We used imitation crab meat because I thought it would be a waste of real crab meat. The imitation crab meat turned out very nicely and was much nicer on the budget. We think it would be better if some chopped red bell pepper was added; maybe about 3/4 cup. It also might have a nice appeal to use shell pasta instead of the spirals and to use 12-16 ounces of the pasta."

"I made this recipe for a friend's birthday dinner and I made a few adjustments: To start, I used real crabmeat, which I seasoned with Old Bay Seasoning Mix and juice from fresh lemon. Then, I added fresh chopped cilantro and a splash of dry white wine. Since there were a lot of people for dinner, I did not freeze the second casserole. I am glad to say that BOTH were totally gone!!!"

"Hello - I'd like to share with you how much my husband enjoyed this for supper last night; made one slight change - used mozzarella instead of cheddar. I am not a big eater, so took my share, then he simply devoured the rest. He's lucky this makes 2 casseroles because it's definitely a keeper!!
