- 1). Begin by pouring a thin layer of pasta sauce in the bottom of the baking dish, just enough to cover it. Spread completely over the bottom of the pan.
- 2). Add a single layer of lasagna noodles on top of the red sauce. Add salt and pepper. Top the noodles with half of the ricotta filling, then add half of the spinach (if you are using it). Add shredded mozzarella and then another layer of red sauce.
- 3). Add another layer of noodles on top of the red sauce. Add more salt and pepper. Top that with the rest of the ricotta filling and the rest of the spinach (if using). Top that with more mozzarella.
- 4). Add another layer of red sauce, then the last layer of noodles. Add salt and pepper. Top this with a thick layer of red sauce and another layer of mozzarella. Top with parmesan or romano cheese and drizzle it with the olive oil. Cover with aluminum foil.
- 5). Bake at 375 F for 25 minutes. Remove the foil and bake for an additional 15 minutes, or until brown and bubbling. Remove the lasagna from the oven and allow to set for 30 minutes before cutting.
