Lasagna with Spicy Sausage

1. Preheat the oven to 350 degrees F and get out an 8×8 baking pan. Set the pan aside.
2. Heat a large saute pan to medium-high heat. Squeeze the sausage out of the casing and into the pan. Cook and brown the sausage until it is almost cooked all the way through. This will take about 3-5 minutes.
3. Add the tomato sauce and continue to cook the sauce with the sausage on low heat for about 5 minutes.
4. Meanwhile, drain your thawed spinach by squeezing the water from it and then wrapping it paper towels to squeeze the excess moisture out.
5. In a medium sized bowl, mix the ricotta cheese, the egg, the garlic and a sprinkle of Kosher salt and fresh black pepper and combine well!
6. When the cheese is smooth, add the spinach in and stir until well combined.
7. Meanwhile, spread a bit of the tomato sauce into the bottom of the pan.
8. Cut the sheets of pasta in half. Place two at a time in a dish of hot water in the sink. Lift the pasta to drain off the water before adding them to the pan. And add two more sheets to the water at the same time.
9. Overlap the two pre-soaked sheets of pasta into the bottom of the pan. Layer half of the cheese mixture and then two sheets of pasta and then 1 cup of mozzarella and ½ of the remaining tomato sauce. Repeat this process with the remaining ricotta, pasta and tomato sauce, reserving the last cup of mozzarella for the top.
10. Drizzle the top with the olive oil.
11. Place the lasagna on a baking sheet and pop it in the 350 degree F oven until hot and golden and bubbly. This will take about 40 minutes.
12. Let cool for about 5 minutes before cutting it into pieces.
13. Serve and enjoy!
