I remember standing on a stool, mesmerized as she assembled the masterpiece, carefully spreading each component.

This Slow-Cooker Spinach Alfredo Lasagna evokes those cherished memories, offering the same rich, creamy indulgence with significantly less effort.

Ingredients

2 1/2 cups shredded Italian cheese blend (10 oz)
2 (15 ounce) jars Alfredo sauce
12 uncooked lasagna noodles
3 cups chopped cooked chicken
1/2 cup freshly shredded Parmesan cheese (2 oz)
1 medium tomatoes, diced
Cooking spray

Equipment Needed

5-quart oval slow cooker
Large bowl
Colander or strainer
Measuring cups and spoons

Instructions

Begin by preparing the spinach. Cook and drain the frozen chopped spinach according to the package directions. This usually involves microwaving or steaming the spinach until thawed and heated through. Once cooked, it’s crucial to remove as much liquid as possible. The best method is to squeeze the spinach using your hands, a clean kitchen towel, or a sturdy strainer. Excess moisture will make the lasagna watery, so this step is vital. Set the squeezed spinach aside.
Prepare your slow cooker by spraying the inside of a 5-quart oval slow cooker with cooking spray. This will prevent the lasagna from sticking to the sides and bottom during cooking.
In a large bowl, combine 1 cup of the shredded Italian cheese blend with the two jars of Alfredo sauce. Mix well until the cheese is evenly distributed throughout the sauce. This cheesy Alfredo sauce will be the delicious foundation for your lasagna layers.
Now, it’s time to assemble the lasagna in the slow cooker. Start by spreading one-fourth of the Alfredo sauce mixture evenly across the bottom of the slow cooker.
Next, create a layer of lasagna noodles. Use approximately 3 uncooked lasagna noodles, breaking them as needed to fit snugly within the slow cooker. The noodles will soften and cook during the slow cooking process.
Continue layering with one-third of the chopped cooked chicken, one-third of the squeezed spinach, and 1/2 cup of the shredded Italian cheese blend. Distribute each ingredient evenly over the noodle layer.
Repeat the layering process twice more: noodles, chicken, spinach, and cheese blend.
Top the final layer of noodles with the remaining Alfredo sauce mixture and sprinkle with the freshly shredded Parmesan cheese.
Cover the slow cooker and cook on Low heat setting for 3 1/2 to 4 1/2 hours, or until the edges are bubbly and the center is heated through. The cooking time may vary depending on your slow cooker, so check for doneness periodically. The lasagna is ready when the noodles are tender and the cheese is melted and slightly browned.
Once cooked, turn off the slow cooker and let the lasagna stand for 10 minutes before serving. This allows the lasagna to set slightly and makes it easier to slice.
Finally, sprinkle the diced tomato over the top of the lasagna before serving. The fresh tomato adds a burst of color and a touch of acidity that complements the richness of the Alfredo sauce.

Expert Tips & Tricks

Don’t Overcook the Spinach: Overcooked spinach can become mushy. Cook it just until wilted, then squeeze out all the excess moisture.
Noodle Placement is Key: When layering the noodles, make sure to cover the entire surface of the previous layer to prevent sauce from seeping to the bottom and potentially burning. Break the noodles strategically to fill gaps.
Cheese Distribution: Ensure even distribution of the cheese in each layer for consistent flavor and texture throughout the lasagna.
Check for Doneness: The best way to check if the lasagna is done is to insert a fork or knife into the center. It should slide in easily with no resistance from uncooked noodles. The edges should be bubbly, and the cheese melted and golden brown.
Make-Ahead Prep: You can assemble the lasagna ahead of time and store it in the refrigerator for up to 24 hours before cooking. This is a great time-saver for busy weeknights. Just add about 30 minutes to the cooking time if starting from cold.
Prevent Burning: If you notice the edges are browning too quickly, you can place a layer of parchment paper between the lasagna and the lid of the slow cooker.

Serving & Storage Suggestions

Serve the Slow-Cooker Spinach Alfredo Lasagna hot, straight from the slow cooker. A sprinkle of fresh basil or parsley adds a vibrant touch. This lasagna pairs beautifully with a simple side salad and crusty bread for soaking up the delicious sauce.

For leftovers, allow the lasagna to cool completely before storing it in an airtight container in the refrigerator. It will keep for up to 3-4 days. To reheat, microwave individual portions or bake in a preheated oven at 350°F (175°C) until heated through.

The lasagna can also be frozen for longer storage. Wrap individual portions tightly in plastic wrap, then place them in a freezer-safe bag or container. Frozen lasagna will keep for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

Pesto Power: Swirl a spoonful of pesto into the Alfredo sauce for a burst of fresh flavor.
Seasonal Twist: In the fall, add roasted butternut squash or pumpkin puree to the filling for a seasonal variation.
