Hi there Shabby Creek Cottage readers, it’s me Claire from A Little CLAIREification back again with your monthly dose of Slow Cooker LOVE! Happy Memorial Day, too! It seemed fitting to make something Italian, right?? Ha. Well that ‘s just how it timed out this month.
Now y’all, I have been itching to try making lasagna in the crock pot and this Spinach Lasagna with Sausage and Mushrooms is just…. a big fat pot of Italian goodness.
I’ll be completely honest that my original approach to making lasagna in a slow cooker was like “Why bother? May as well just make it in the oven!” But what I like about this is, while yes – there is about 20 minutes prep – it cooks for 5 hours and does it’s own thing without me hovering over an oven. I can get a WHOLE lot done in 5 hours, you guys!
Now this is by far the hardest slow cooker recipe I have ever had to photograph. My frustration was mounting and, frankly, the lasagna was disappearing really fast. My Husband happened to wander out during this photography frustration – he may or may NOT have had a plate of lasagna in hand – and he looked at me like I had a third head.
He basically told me I was being ridiculous and that it was delicious. And that it is, my friends, so in the end he was right. There was no way I couldn’t share this one with you all. Not only is it amazing when it comes out all bubbly and hot but if you refrigerate it overnight it slices beautifully. Instant lunch or dinner.
I cooked it on HIGH heat for 5 hours so I can only imagine it would work on LOW for 6-8 hours but I didn’t try that. I’m pretty daring, though. Especially since the sausage is cooked already. Maybe next time I’ll layer it and refrigerate overnight then set on LOW heat for 8 hours the next day. I may just add a little extra sauce.
So while this one does entail a little prep and layering, I am telling you it’s definitely worth it for an easy dinner and fantastic leftovers! In fact, I am eating the last lone slice right now as I finish writing this.
I hope you all have had a wonderful holiday weekend and I’ll see you right back here next month. Come on by in the meanwhile and say hello!

Hi Claire and Gina! This looks delicious, Claire! I’ve never tried lasagna in a crockpot, either, but love how easy it sounds and it looks wonderful. Thanks so much for sharing and pinning! Hope you’re both having a fantastic Wednesday!

Love this crockpot lasagna! It looks fantastic and I can’t wait to try it – especially with all that fresh spinach – thanks for sharing Claire and Gina – pinned π
My question is, Why do I cook the meat first, before putting it in the crock pot?? Won’t it cook in the crock, especially ON HIGH for 5 hours?? My oven is not working so by seeing this recipe reminding me of the food that can be cooked really saved me a big headache.
