Need a dinner that practically cooks itself? This slow cooker chicken lasagna will blow your mind! I discovered this trick when our schedule got crazy. Now we can't get enough of these delicious layers - juicy chicken, velvety sauce, and mountains of cheese that come together while you're busy handling everything else in your day.

What You'll Need

  • Chicken: Use a store-bought rotisserie chicken to cut down prep time!
  • Sauce Base: Jarred or homemade Alfredo sauce works perfectly.
  • Quick Noodles: Grab those time-saving no-boil lasagna sheets.
  • Dairy Blend: A mix of ricotta, parmesan and mozzarella for ultimate creaminess.
  • Green Addition: Baby spinach gives nice color and sneaks in veggies!
  • Flavor Boosters: Garlic, Italian herbs, pepper and salt.

Assembly Steps

Prepare The Dairy Mixture
Combine all cheeses with eggs and seasonings in a bowl until well blended.
Create Your Stack
Start with greasing the slow cooker, then alternate sauce, noodles, cheese blend, chicken and spinach until ingredients are used up.
Walk Away
Cover and let it cook on low for 4 hours. You'll catch amazing smells throughout your home!
Finishing Touch
Sprinkle extra cheese on top and let it melt for about 15 minutes. Give it a moment before serving!

Tips For Success

Go for a thicker alfredo sauce as it won't get watery. Make sure your layers are even to avoid dry patches. Don't rush to serve - it needs time to firm up after cooking, just like traditional lasagna.

Fun Variations

  • Swap chicken for portobello mushrooms for a veggie version.
  • Add some red pepper flakes for a kick of heat.
  • Try swapping spinach with thinly sliced zucchini or kale.
  • Top with crunchy fried onions right before eating for texture!

Storage Options

Leftovers stay good in the fridge for about 4 days if you don't finish it all first! Want to save it longer? Pop it in the freezer, wrapped tightly, for up to 3 months. Just heat it through in your microwave or oven whenever you're craving it again.

Complete Your Dinner

Add some buttery garlic bread and a simple green salad on the side. Treat yourself to a nice glass of wine or some bubbly water to make dinner feel special. It's like restaurant-quality food without leaving your kitchen!
