Total Time: 1 hour 20 minutes

Servings: 15

Ingredients

  • 2 tablespoons homemade Italian seasoning (divided)
  • 6 ounce bag baby spinach
  • 1/2 white onion (chopped)
  • 15 ounce can diced petite tomatoes (drained)
  • 4 garlic cloves (minced)
  • 4 eggs
  • 32 ounce ricotta cheese
  • 1 cup Parmesan cheese (plus extra for topping)
  • 20 sheets no-boil lasagna
  • 67 ounce marinara sauce
  • 4 cups shredded mozzarella cheese (divided)
  • 1 cup Parmesan cheese (plus extra for topping)
  • 10 turkey sausage links (sweet or spicy, cooked, remove from casing and crumbled, about 2 pounds)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease a deep 9×13-inch baking dish.
  2. In a large bowl, combine the ricotta cheese, eggs, 1 cup of Parmesan cheese, and 1 tablespoon of the Italian seasoning. Mix well and set aside.
  3. In another large bowl, combine the marinara sauce, drained diced tomatoes, cooked crumbled turkey sausage, chopped onion, minced garlic, and the remaining 1 tablespoon of Italian seasoning. Stir until everything is well incorporated.
  4. To assemble, spread about 1 1/2 cups of the meat sauce mixture evenly on the bottom of the prepared baking dish.
  5. Arrange 4-5 no-boil lasagna sheets over the sauce, slightly overlapping to fit.
  6. Spread half of the ricotta mixture evenly over the noodles. Top with half of the baby spinach (tearing any large leaves), then sprinkle with 1 cup of shredded mozzarella cheese.
  7. Spoon another 1 1/2 cups of meat sauce over the mozzarella layer.
  8. Place another layer of 4-5 lasagna sheets over the sauce. Repeat the layering: remaining ricotta mixture, remaining spinach, and 1 cup of mozzarella.
  9. Add another 1 1/2 cups of sauce, then another layer of noodles. Top with all the remaining meat sauce.
  10. Finish by sprinkling the remaining 2 cups of mozzarella cheese and extra Parmesan cheese over the top.
  11. Cover the dish tightly with aluminum foil (tented slightly so it doesn’t touch the cheese). Bake for 50 minutes.
  12. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
  13. Let the lasagna rest for at least 15-20 minutes before slicing and serving. This allows the layers to set for cleaner slices.

Variations

  • Vegetable-First Layer: Instead of mixing spinach into the layers, sauté it with the onion and garlic for a more integrated flavor.
  • Spice it Up: Use spicy turkey sausage and add a pinch of red pepper flakes to the sauce mixture for a kick.
  • Meatless Twist: Simply omit the turkey sausage. The lasagna will still be hearty and flavorful.
  • Individual Servings: Assemble the lasagna in smaller, disposable foil pans for easy, pre-portioned meals to freeze or gift.

Tips for Success

  • Ensure your sauce mixture is not too thick or dry; the moisture is crucial for hydrating the no-boil noodles.
  • Letting the lasagna rest after baking is non-negotiable for neat slices.
  • Press the spinach and other layers down gently when assembling to eliminate large air pockets.
  • If your ricotta mixture seems very thick, a splash of milk can help loosen it for easier spreading.

Storage & Reheating

Let the lasagna cool completely, then cover tightly or transfer portions to airtight containers. Store in the refrigerator for up to 4 days. For longer storage, freeze for up to 3 months. Reheat individual portions in the microwave or larger pieces, covered with foil, in a 350°F oven until heated through.

FAQ

Can I use regular lasagna noodles instead?

No, this recipe is specifically designed for no-boil (oven-ready) noodles. Regular noodles will not cook properly with this method and will remain hard.

Why do I need eggs in the ricotta mixture?

The eggs act as a binder, helping the ricotta layer set up firmly during baking for distinct, non-runny layers.

Can I assemble this ahead of time?

Absolutely. Assemble the lasagna, cover tightly, and refrigerate for up to 24 hours before baking. You may need to add 5-10 minutes to the covered baking time.

Do I have to drain the canned tomatoes?

Yes, draining them prevents the final dish from becoming too watery.

Can I use fresh spinach instead of baby spinach?

Yes, but be sure to chop it finely. You may need to wilt it slightly in a pan with a tiny bit of water, then drain well, to reduce its volume.

Is it okay if some of the noodles are exposed on the top layer?

It’s best to cover all noodles completely with sauce to ensure they cook through. The top layer of sauce and cheese protects them.
