Prep & Cook Time

Prep Time: 20 minutes
Cook Time: 60 minutes
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)
10 turkey sausage links (sweet or spicy, cooked, remove from casing and crumbled, about 2 pounds)

Instructions

Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine the ricotta cheese, 4 eggs, 1 cup of Parmesan cheese, and 1 tablespoon of the Italian seasoning. Mix well and set aside.
In another large bowl, combine the drained petite diced tomatoes, crumbled cooked turkey sausage, chopped onion, minced garlic, and the remaining 1 tablespoon of Italian seasoning. Stir to combine.
To assemble the lasagna, spread about 1 ½ cups of the marinara sauce evenly over the bottom of a 9×13 inch baking dish.
Place 5 sheets of no-boil lasagna noodles over the sauce in a single layer, breaking them as needed to fit.
Spread half of the ricotta mixture over the noodles.
Scatter half of the baby spinach leaves over the ricotta.
Spoon half of the sausage and tomato mixture over the spinach.
Sprinkle 1 cup of the shredded mozzarella cheese over the sausage layer.
Repeat the layers: sauce, 5 noodles, remaining ricotta, remaining spinach, remaining sausage mixture, and another 1 cup of mozzarella.
Place the final layer of 5 noodles over the mozzarella.
Pour the remaining marinara sauce evenly over the top, ensuring all noodles are covered.
Top with the remaining 2 cups of shredded mozzarella cheese and an extra sprinkle of Parmesan cheese.
Cover the baking dish tightly with aluminum foil.
Bake, covered, for 50 minutes.
Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
Let the lasagna rest for 15-20 minutes before slicing and serving.

Variations

Vegetarian Twist: Simply omit the turkey sausage and add a layer of sautéed sliced mushrooms or zucchini ribbons with the spinach.
Extra Cheesy: Add a thin layer of shredded provolone or fontina cheese between each major layer.
Meat Lover’s: Mix the crumbled sausage with an equal amount of cooked ground beef or Italian sausage.
Individual Servings: Assemble the lasagna in smaller, oven-safe dishes for easy single servings and reduce the baking time by 10-15 minutes.

Tips for Success

Ensure the sauce completely covers the top layer of noodles to prevent dry, hard edges.
Letting the lasagna rest after baking is crucial; it allows the layers to set for cleaner slices.
If your marinara sauce is very thick, you can thin it with ½ cup of water or broth to provide enough moisture for the no-boil noodles.
Press layers down gently as you assemble to eliminate large air pockets.

Storage & Reheating

Store leftover lasagna, covered, in the refrigerator for up to 4 days. For longer storage, wrap individual portions tightly and freeze for up to 3 months. Reheat slices in the microwave or, for best texture, cover with foil and warm in a 350°F oven until heated through.

FAQ

Can I use regular lasagna noodles?

No, this recipe is specifically designed for “no-boil” or “oven-ready” lasagna noodles. Regular noodles require pre-boiling and will not cook properly with this method.

My lasagna seems watery. What happened?

This is often due to not draining the canned tomatoes well or using a marinara sauce with high water content. Always drain tomatoes thoroughly and consider simmering your sauce for a few minutes to reduce it slightly before assembling.

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 if it goes into the oven cold.

Do I have to use homemade Italian seasoning?

While homemade is ideal for flavor control, you can substitute an equal amount of store-bought Italian seasoning blend.

Can I freeze the baked lasagna?

Yes, it freezes very well. Cool completely, wrap the whole dish or individual portions tightly in plastic wrap and foil, and freeze. Thaw in the refrigerator overnight before reheating.

What if I don’t have a 9×13 inch dish?

You can use two smaller dishes. Just adjust the number of noodle sheets per layer accordingly and keep an eye on the baking time, as it may cook slightly faster.
