Slow Cooker Spinach and Crab Lasagna

Recipe by  

"Spinach, crab, mushrooms, and lasagna are my hubby's favorite foods. Combine in the slow cooker and wow. I about shocked myself at how good this turned out! You can substitute real crab or shrimp for mock crab. If you turn off the slow cooker and allow lasagna to cool after the 30 minutes after adding mozzarella cheese, it will stick together better!"

I made this tonight and it was really good. I didn't precook the noodles but i did buy oven ready noodles. I dont know if that made a difference but they came out perfectly. I added 1 8oz jar of lump crab meat. Also, i cooked mine for 2 hrs and 15 minutes, well because i misread the cooking time. It still came out great. I put everything together at the same time. I didn't wait to add the cheese and it still was good. I waited for 45 minutes for it to cool instead of 30 minutes, then i ate it. It was really, really good. I seasoned the crab meat prior to cooking and i chopped the mushrooms up into small pieces to make sure they cooked, like someone suggested.

I tried this recipe subbing Johnsonville mild Italian sausage, cooked and drained. I followed the recipe, but used a 5oz container of spinach. This really requires a larger style crock pot. I used a crock pot liner in my medium crock pot and had to move the liner to the larger one. Another issue was I felt it really needed extra sauce. Also, upon reading the reviews I was unsure about the noodles, to use dry, pre-cook, or use oven ready ones. I chose the oven ready type and found the texture chewy all the way through. I would use regular boiled noodles. I was not sure how to fix the noodle issue. 2 pieces were eaten and the rest could not be salvaged. This recipe may work if the right noodles are used.

I cooked this for dinner tonight. I changed the recipe to my liking and it turned out wonderful! I do not like imitation crabmeat at all.. does not taste anything like blue crab! It is a bit more expensive, but I used real blue crab meat (claw meat). I used the oven ready noodles and had no problems. I also mixed two small cans of cream of mushroom soup into the Alfredo sauce to add more mushroom flavor. I did not use cottage cheese since my husband is not a fan of that. I also used mozzarella cheese on each layer on top of the ricotta cheese. He loves it ! This recipe is excellent on a cold night and for anyone who enjoys eating blue crab !!

I made this for dinner tonight and it's amazing. I stuck pretty close to the recipe, with a couple changes. I wasn't sure if I was to cook the noodles or not as it wasn't stated, so I cooked them just enough to be pliable. I used sliced baby Bella's (8 oz package) and then diced the slices per a previous review suggestion. I also used a full container of ricotta and a full container of cottage cheese, mixed them together and spread them that way. I sprinkled some garlic powder and salt as I was worried it may be a little was AWESOME!!! Very very good and definitely will make this again. Note that it s hard to get out of the crockpot, as it becomes juicy, but definitely worth it.

Just made it today for the family. My husband and I loved it. I had to adjust the amount of some ingredients though. I used only 8 oz of lasagna noodles but 16 oz of crabmeat. Also, next time I'd chop mushrooms smaller, sliced mushrooms didn't have time to finish cooking. I don't mind mushrooms crunchy or chewy but for guests I would cut them up smaller. Overall, it was very tasty and light.

Excellent recipe! I did not precook the noodles and they came out perfectly. I also added cocktail shrimp and garlic salt for a little more flavor. Small scallops would be a nice addition too. Or stick to the original recipe, it's a good one!

Can someone tell me if they've ever used Marinara instead of Alfredo sauce? I dislike Alfredo sauce but this recipe looks so good.

Luckily I chose a dish too small to hold the leftovers. This gave me and my hubby the opportunity to eat the extra right out of the crockpot. This dish was not only easy to make, it was fabulous. My taste buds are still smilin! Thanks for sharing.
