Ingredients

Scale

Olive Oil

  • 4 tablespoons olive oil, divided

Pasta

  • 1 pound taccole pasta or broken-up sheets of lasagna

Flavorings

  • 1 clove garlic, chopped
  • 1 teaspoon Giadzy Spicy Seasoned Salt, divided
  • Kosher salt, for the pasta water

Vegetables

  • 1 (5-ounce) container baby spinach
  • 1 red onion, diced

Dairy

  • 1 cup whole milk ricotta cheese
  • 2 ½ cups shredded low-moisture mozzarella, divided
  • 1 ½ cups freshly grated Parmigiano Reggiano, divided

Meat

  • 1 pound spicy Italian sausage, casings removed

Tomato Sauce

  • 3 (12.34-ounce) jars Giadzy Passata or 3 cans Corbara Tomatoes

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 425°F (220°C) and grease a straight-sided 12×17-inch baking sheet with 1 tablespoon of olive oil. Set it aside for later use.
  2. Cook Spinach Mixture: Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the chopped garlic and ½ teaspoon of the Giadzy Spicy Seasoned Salt. Sauté until fragrant, about 1 minute. Add the baby spinach and cook, stirring occasionally, until wilted and the water has evaporated, about 5 minutes. Remove the spinach from the skillet, chop it finely with scissors, and combine with the ricotta cheese in a medium bowl. Set the mixture aside.
  3. Prepare the Sausage Sauce: Wipe out the skillet, return it to medium heat, and add the remaining 2 tablespoons olive oil. Add the spicy Italian sausage and cook undisturbed for 3 minutes, then break it apart with a wooden spoon. Continue cooking, stirring often, for another 5 minutes until browned. Add the diced red onion and cook until softened, about 3 minutes. Stir in the jars of Giadzy Passata (or canned Corbara Tomatoes with juices) along with the remaining ½ teaspoon of Spicy Seasoned Salt. To ensure no sauce is wasted, swirl in about 2 tablespoons of water in each jar before adding it. Remove the sauce from heat.
  4. Cook the Pasta: Bring a large pot of salted water to a boil. Cook the taccole pasta or broken lasagna sheets for about 4 minutes until very al dente, stirring frequently to prevent sticking. Using a pasta spider or slotted spoon, transfer the cooked pasta directly into the skillet with the sausage tomato sauce. Add ½ cup of reserved pasta water, 1 cup mozzarella, and ½ cup Parmigiano. Stir thoroughly to combine all ingredients.
  5. Assemble the Dish: Transfer the pasta and sauce mixture evenly into the prepared baking sheet. Dollop the ricotta and spinach mixture evenly across the top. Sprinkle with the remaining 1 ½ cups shredded mozzarella and 1 cup grated Parmigiano Reggiano.
  6. Bake and Serve: Bake in the preheated oven for 30 minutes, or until the top is bubbly and golden brown. Remove from the oven and let cool for 5 minutes before slicing into squares. Serve warm, optionally with extra warm passata or marinara sauce on the side.

Notes

  • Use taccole pasta or broken lasagna noodles for best texture in this sheet pan lasagna.
  • Adjust the spicy seasoned salt to taste if you prefer milder or more intense flavors.
  • If using canned Corbara tomatoes, crush them in the pan to create a chunky sauce, which adds texture.
  • Letting the dish rest after baking helps it set for easier slicing.
  • Feel free to substitute spicy Italian sausage with sweet Italian sausage or ground turkey for a different taste.
