Preheat oven to 350 degrees.
Bring a large pot of water to a boil and cook lasagna noodles according to package instructions. Drain and rinse with cool water. Set aside until ready to use.
Prepare 10 Minute Vegan Marinara according to instructions. Add ricotta, parmesan, milk, spinach, Italian seasoning and a pinch of salt & pepper to a bowl. Stir until well combined - add more milk if you want a thinner consistency. To assemble, spoon 1/2 cup of marinara sauce on the bottom of a 13 x 6 baking pan. Layer 3 lasagna noodles over the marinara and spoon 1/3 of the remaining marinara on top of the noodles followed by 1/3 of the ricotta mixture. Repeat layers - noodles, marinara, ricotta, noodles, marinara, ricotta.
Spray a piece of foil with non-stick spray and cover the lasagna. Place in the oven for 20 minutes. Remove the foil and cook for an additional 10 minutes.
For a crispier topping, turn the oven to broil, cook for an additional 2-5 minutes (or until desired browning is reached - be sure to keep an eye on it while the oven is on broil).
Remove the lasagna from the oven and allow to rest for 10 minutes. Slice into 6 pieces and serve.****
