When cravings for cozy, cheesy layers kick in but you just can't deal with extra steps, slow cooker chicken lasagna comes to the rescue. Toss everything in, go enjoy your day, and come home to an ultra-comforting Italian-inspired meal that tastes like way more work than it is.
I started making this on chaotic weeknights and the very first time, everyone hovered by the counter, peeking and sniffing. Now it's in the regular rotation, especially when rotisserie chicken ends up in my fridge.
Irresistible Ingredients
- Eggs: big eggs from the cold side of your fridge work to pull all that cheese together
- Italian seasoning: a lively dried herb blend—pick one that smells fresh when you open it
- Ground black pepper: grind fresh if you can, it brings a gentle heat
- Salt: go for kosher salt so every bite pops
- Garlic: only use fresh here—pick firm bulbs, skip any with green shoots
- Ricotta cheese: you want full-fat for dreamy texture, look for one that's creamy not gritty
- Parmesan cheese: sharp and nutty—grab a wedge and grate yourself if possible
- Baby spinach: roughly chop and look for leaves that are firm and totally green
- Oven-ready lasagna noodles: cut your prep down—make sure they're flat and not broken
- Mozzarella cheese: shred a block yourself for that stretchy, melty finish
- Alfredo sauce: creamy and cheesy, pick one with just a few real ingredients
- Rotisserie chicken: pull apart for juicy flavor, just make sure it's fresh and not dried out
Simple Step-by-Step
- Finish with Cheese:
- Power off the cooker, toss on as much mozzarella as you like, cover for ten-ish minutes so it gets gooey and everything holds together. Slices come out like a dream.
- Cook it Low and Slow:
- Pop on the lid, set it to low, and let it go for roughly four hours—seriously, don’t keep lifting the lid so all the delicious steam stays inside.
- Final Layer and Cook:
- Top with one more layer of noodles, dump on the rest of the Alfredo and spinach, and gently spread so every noodle gets covered for max softness.
- Build the Second Layer:
- Another round of noodles, then repeat: cheese mixture, sauce, chicken, spinach. The more layers, the yummier it stacks up.
- Begin the First Layer:
- Layer half your Alfredo over the noodles, use a spatula to get it even. Scoop half the cheese on top, then scatter chicken and spinach. Press it down gently.
- Start Layering:
- Spoon about 3/4 cup Alfredo into the cooker base, all the way out to the edges. Cover that with enough noodles to reach the sides, snapping to fit if you need to.
- Make the Cheese Filling:
- Stir together mozzarella, ricotta, parmesan, eggs, garlic, salt, pepper, and Italian seasoning in a big bowl till it’s creamy and speckled with herbs.
- Prep the Slow Cooker:
- Hit your slow cooker’s sides and bottom with nonstick spray—don’t skimp. You’ll thank yourself when those melty layers come out easy.

My family is obsessed with how rich and gooey this dish comes out and I'll never forget making it for the first time on a stormy Sunday We could smell the creamy sauce from the hallway and every time we make it, the whole house feels a little cozier
Best Ways to Store
Let it chill out on the counter before slicing or moving it around. Keep any extras tightly wrapped in the fridge for up to 4 days. For neat pieces, only slice after it’s cooled, then use a spatula to serve.
Switch Things Up
Leftover turkey or ham works great instead of chicken. For lighter bites, swap in cottage cheese for half the ricotta, or toss in kale instead of spinach. Want to punch up the flavor? Stir in some jarred pesto for an extra herby kick.
How to Serve
Pair hefty squares with a crunchy salad or oven-roasted veggies. Sprinkle fresh basil or add juicy cherry tomatoes on top for more color. Everyone loves garlic bread—let them dip it in all that saucy goodness.

Behind the Dish
This isn’t your Italian nonna’s version—it’s a shortcut for busy people, mixing the best of homey American ease with those classic lasagna feels. Chicken and Alfredo together make this pure comfort with a twist. Somehow, it still tastes both classic and brand new.
