Follow these step-by-step instructions to create your delicious Holiday Alfredo Lasagna:

Step 1: Prepare the spinach and ricotta mixture

1. Heat olive oil in a skillet over medium heat. Add minced garlic and sauté until fragrant (about 1 minute).
2. Add the fresh spinach and cook until wilted. If using frozen spinach, ensure it is fully thawed and drained before adding it to the skillet.
3. In a large mixing bowl, combine ricotta cheese, sautéed spinach, eggs, 1/4 cup Parmesan cheese, salt, pepper, and Italian seasoning. Mix well until fully combined and set aside.

Step 2: Cook the lasagna noodles

1. If you’re using regular lasagna noodles, bring a large pot of salted water to a boil. Cook the noodles according to package instructions, typically 8-10 minutes, until they are al dente.
2. Drain the noodles and lay them flat on parchment paper to prevent them from sticking together. If using oven-ready noodles, skip this step.

Step 3: Prepare the Alfredo sauce (if making from scratch)

1. In a medium saucepan, melt butter over medium heat.
2. Add minced garlic and cook for 1-2 minutes until fragrant.
3. Stir in heavy cream and let the mixture simmer for 3-4 minutes.
4. Gradually whisk in the Parmesan cheese until the sauce becomes smooth and creamy. Season with salt and pepper to taste.
5. Remove from heat and set aside.

Step 4: Assemble the lasagna

1. Preheat your oven to 375°F (190°C).
2. In a 9×13-inch baking dish, spread a thin layer of Alfredo sauce to coat the bottom.
3. Lay 3 lasagna noodles on top of the sauce, ensuring they slightly overlap.
4. Spread 1/3 of the ricotta-spinach mixture evenly over the noodles.
5. Pour another layer of Alfredo sauce over the ricotta-spinach layer and sprinkle with shredded mozzarella cheese.
6. Repeat the layering process: noodles, ricotta-spinach mixture, Alfredo sauce, and mozzarella cheese, until you’ve completed three layers. Finish with a top layer of noodles and pour the remaining Alfredo sauce over the top. Sprinkle the final layer of mozzarella and the remaining Parmesan cheese.

Step 5: Bake the lasagna

1. Cover the lasagna with aluminum foil and bake in the preheated oven for 25 minutes.
2. After 25 minutes, remove the foil and bake for an additional 15-20 minutes, or until the cheese is golden and bubbly.
3. Once baked, remove from the oven and let the lasagna rest for 10-15 minutes before slicing. This helps it set and makes it easier to serve.
