Ingredients

  • 4 cups whole milk
  • 15 lasagna noodles, not no-boil
  • hot water, to taste
  • 1 tablespoon olive oil
  • 1 pound sweet or hot Italian sausage, ground or links with casings removed
  • 1 medium yellow onion, diced
  • 3 cloves garlic, minced
  • 1 pound baby spinach
  • 2 3/4 teaspoons kosher salt, divided
  • 1/2 teaspoon freshly ground black pepper, divided
  • 1 stick unsalted butter
  • 1/2 cup all-purpose flour
  • ground nutmeg, to taste
  • 3/4 cup parmesan cheese, grated, divided
  • 1 (15-16-ounce) container whole-milk ricotta cheese
  • 1 (12-ounce) package low-moisture whole-milk or part-skim mozzarella cheese, shredded

Directions

Step 1 -Allow the whole milk to come to room temperature.

Step 2 -Position an oven rack to the middle position in the oven, then preheat the oven to 400 degrees F.

Step 3 -In a 9x13-inch, arrange the lasagna noodles in an even layer.

Step 4 -Cover the noodles in the baking dish with the hot water and allow them to soak while preparing the filling and the sauce, about 30 minutes.

Step 5 -In a large Dutch oven or pot over medium-high heat, add the olive oil and heat until it is shimmering.

Step 6 -Add the sausage to the hot oil and cook, while crumbling, until it is no longer pink, about 5-7 minutes.

Step 7 -Add the onions and the garlic to the sausage and cook, while stirring occasionally, until the onions are softened and translucent, about 5 minutes.

Step 8 -Add the spinach, a few handfuls at a time, to the sausage mixture and cook, while stirring, until it is just wilted, about 3-5 minutes.

Step 9 -Season the sausage mixture with 1/2 teaspoon of the kosher salt and 1/4 teaspoon of the black pepper.

Step 10 -Transfer the Dutch oven from the heat and allow it to cool.

Step 11 -In a large saucepan over medium heat, melt the butter.

Step 12 -Add the flour to the melted butter and cook, while whisking constantly, until a bubbling paste forms, about 2 minutes. The paste should look like it is beginning to dry out slightly.

Step 13 -Gradually whisk the room temperature milk into the butter mixture and continue to whisk until no lumps remain.

Step 14 -Increase the heat to high and bring the milk mixture to a boil.

Step 15 -Reduce the heat to medium-low and allow the milk mixture to simmer, while stirring occasionally, until thickened into a béchamel sauce, about 1-2 minutes.

Step 16 -Season the béchamel sauce with 2 teaspoons of the remaining kosher salt and the ground nutmeg and stir to combine.

Step 17 -Transfer the saucepan from the heat.

Step 18 -In a medium bowl, add 1/2 of the parmesan cheese, the ricotta cheese, the remaining salt, and the remaining black pepper and stir to combine.

Step 19 -Drain the lasagna noodles, then transfer them to a plate.

Step 20 -In the 9x13-inch baking dish, add 1/4 cup of the béchamel sauce, spreading it out evenly.

Step 21 -Arrange 5 of the lasagna noodles in an even layer on top of the sauce layer. You may break them as needed to fit; it is okay if the noodles overlap slightly.

Step 22 -Dollop and spread 1/2 of the ricotta mixture over the noodle layer in the baking dish.

Step 23 -Spoon 1/2 of the sausage mixture over the ricotta layer in the baking dish, spreading it out evenly.

Step 24 -Sprinkle the sausage mixture layer with 1 cup of the mozzarella.

Step 25 -Dollop and spread 1 heaping cup of the remaining béchamel sauce over the mozzarella layer.

Step 26 -Repeat the layers with 5 of the remaining lasagna noodles, the remaining ricotta mixture, the remaining sausage mixture, 1 cup of the remaining mozzarella, and 1 heaping cup of the remaining béchamel sauce, in that order.

Step 27 -Top with the remaining lasagna noodles, the remaining béchamel sauce, the remaining mozzarella cheese, and the remaining parmesan cheese, in that order.

Step 28 -Bake the lasagna, uncovered, until the cheese is melted and lightly browned and the sauce is bubbling, about 30 minutes.

Step 29 -Allow the lasagna to cool on a wire rack for 15 minutes.

Step 30 -Serve.
