White Spinach Lasagna

Creamy, hearty, and packed with flavor, this White Spinach Lasagna is the kind of comforting baked pasta dish that feels special but is surprisingly simple to make. Instead of traditional red sauce, this version leans into a rich, creamy Alfredo base layered with savory Italian sausage, spinach and artichoke dip, and plenty of parmesan. The result is indulgent, cozy, and deeply satisfying. The kind of meal that fills your kitchen with warm, bubbling goodness and brings everyone to the table.
What makes this recipe especially approachable is the use of oven-ready lasagna noodles. There’s no need to boil pasta or juggle extra pots. Everything layers right into the baking dish and cooks together into a creamy, cohesive casserole. It’s perfect for feeding a crowd, bringing to a potluck, or making ahead to stock your freezer for busy weeks.
This is comfort food that feels a little elevated without being complicated.

Equipment

  • Skillet
  • Large mixing bowl
  • 9x13 Baking dish

Ingredients

  • 2 lbs ground Italian sausage browned and drained
  • 1 can petite diced tomatoes drained
  • 2 16 oz containers spinach & artichoke dip
  • italian seasoning to taste
  • crushed red pepper to taste
  • onion powder to taste
  • garlic powder to taste
  • 1 14 oz jar alfredo sauce divided (use ¾ in filling, ¼ for the pan)
  • 8 oz parmesan cheese divided: 4 oz for the filling and 4 oz for the topping
  • oven-ready lasagna noodles
  • 1 splash milk

Instructions

  • Preheat your oven to 375°F.
  • In a large skillet over medium heat, brown the ground Italian sausage until fully cooked, breaking it up into crumbles as it cooks. Drain any excess grease to keep the filling rich but not heavy.
  • In a large mixing bowl, combine the browned sausage, drained diced tomatoes, spinach and artichoke dip, Italian seasoning, crushed red pepper, onion powder, garlic powder, ¾ of the Alfredo sauce, and 4 ounces of the Parmesan cheese. Stir until everything is evenly combined and creamy.
  • Spread the remaining ¼ jar of Alfredo sauce evenly across the bottom of a 9x13 baking dish. Add a small splash of milk to the empty jar, shake to loosen the remaining sauce, and pour that into the pan as well. This helps create extra moisture so the oven-ready noodles cook perfectly.
  • Begin layering: place a layer of oven-ready lasagna noodles over the sauce, then spread a generous layer of the sausage mixture on top.
  • Repeat the layers: noodles and filling until you have three total layers, finishing with the sausage mixture on top.
  • Sprinkle the remaining 4 ounces of Parmesan cheese evenly over the top.
  • Cover tightly with foil and bake for 25 minutes. This allows the noodles to soften and the flavors to meld together.
  • Remove the foil and bake for an additional 5 minutes.
  • Switch the oven to broil and broil for about 5 minutes, watching closely, until the top becomes golden and bubbly.
  • Remove from the oven and let stand for 10–15 minutes before slicing. This resting time helps the layers set and makes serving easier.

Notes

Why This Recipe Works

The combination of Alfredo sauce and spinach artichoke dip creates a creamy, flavorful base without needing to prepare a homemade white sauce from scratch. The Italian sausage adds depth and a savory bite that balances the richness of the cheese and cream. The diced tomatoes bring just enough acidity to keep everything from feeling too heavy.
Using oven-ready noodles simplifies the process and keeps cleanup minimal. As the lasagna bakes, the noodles absorb the creamy sauce and become perfectly tender. The splash of milk ensures there’s enough moisture for even cooking.
The final broil step is what takes this dish from good to irresistible giving you that golden, bubbly, slightly crisp cheese topping that everyone fights over.

Serving Suggestions

White Spinach Lasagna is hearty enough to stand alone, but it pairs beautifully with lighter sides. A crisp green salad with a simple vinaigrette helps balance the richness. Garlic bread or warm breadsticks are perfect for scooping up every last bit of sauce.
For a vegetable side, try roasted broccoli, asparagus, or green beans. The brightness of roasted vegetables contrasts nicely with the creamy layers of the lasagna.

Make-Ahead and Freezer Tips

This lasagna is ideal for making ahead. You can assemble it completely, cover tightly, and refrigerate for up to 24 hours before baking. Just add a few extra minutes to the covered bake time if cooking straight from the refrigerator.
It also freezes beautifully. Assemble the lasagna in a freezer-safe dish, wrap tightly in plastic wrap and foil, and freeze for up to 2–3 months. Thaw overnight in the refrigerator before baking as directed.
This White Spinach Lasagna is rich, creamy, and incredibly satisfying. A comforting baked dish that feels special enough for guests but simple enough for a weeknight. It’s hearty, flavorful, and layered with everything we love about classic comfort food, just with a creamy twist.
