Finely chop the pancetta, onion, and carrots. Alternatively, you can pulse the pancetta in the food processor until a chunky paste forms. Transfer to a bowl. Then, pulse the onion and carrots in the food processor.
4 ounces pancetta, 1 medium onion, 2 medium carrots
Add the olive oil and the chopped pancetta to a large skillet over medium-high heat. Cook until the pancetta is browned and slightly crispy. Add in the Italian seasoning, carrots, and onion, cooking for about 7-8 minutes, until softened. Add in the garlic and cook for 1 minute, until fragrant.
2 tablespoons olive oil, 2 teaspoons Italian seasoning, 3 cloves garlic
Stir in the ground chicken, breaking it up into pieces. Cook until browned. Stir in the marinara sauce and let everything simmer for a few minutes. Then, remove the sauce from the heat.

Preheat the oven to 400℉. Grease a 9×13 casserole dish with cooking spray.
In a bowl, combine the ricotta cheese, spinach, garlic, egg, salt, and pepper.
15 ounces ricotta cheese, 2 cups chopped fresh spinach, 1 large egg, 1 pinch kosher salt and freshly ground black pepper
To assemble the lasagna, layer 1 cup of meat sauce on the bottom of the prepared casserole dish. Then layer with the following: an even layer of lasagna noodles; 2½ cups of meat sauce; a few spoonfuls of the ricotta mixture; a sprinkle of mozzarella cheese and Parmesan cheese.

Repeat the layers once more, in the same order. Then, finish with a final layer of noodles, the remaining meat sauce, and a generous sprinkling of mozzarella.
Cover the lasagna with tin foil and bake for 40 minutes. Then remove the tin foil, and bake for an additional 10-15 minutes.
Remove the lasagna from the oven, and let it rest for 10-15 minutes before slicing and serving. Garnish with chopped parsley, basil, Parmesan cheese, and red pepper flakes if desired.
