Ingredient Breakdown: What You’ll Need

Let’s take a closer look at what makes this lasagna so delicious.

Lasagna Noodles

Use regular, uncooked lasagna noodles (not oven-ready). The long cook time allows them to soften perfectly.

Ricotta Cheese

Creamy, mild, and perfect for layering, ricotta brings a luscious texture to every bite.

Shredded Mozzarella

Melted mozzarella adds the perfect cheesy stretch. Use whole milk for extra richness.

Parmesan Cheese

Adds a salty, nutty depth to the cheese mixture and the top layer.

Frozen or Fresh Spinach

Spinach adds a dose of iron and a beautiful green hue. Be sure to squeeze out excess moisture if using frozen spinach.

Marinara Sauce

Choose a high-quality store-bought marinara or make your own. Look for one with low added sugar and rich tomato flavor.

Egg

Used in the cheese mixture to help it set.

Garlic, Onion, and Italian Seasoning

These aromatics and herbs infuse flavor throughout the dish.

Q: Can I use fresh spinach instead of frozen?

Q: Do I need to cook the noodles first?
No. They cook perfectly in the sauce during the slow cooking process.

Q: Can I double the recipe?
If your slow cooker is large enough, yes. Just add more layers and extend the cooking time slightly.
