Preheat the oven to 375
Mix the Ricotta with the egg, oregano, basil and one garlic clove minced.
Layer the lasagna in a greased loaf pan starting with the marinara sauce on the bottom and ending the layers with marinara and cheese on top.
Cook covered with foil at 375 for 30 minutes then uncovered for 15 minutes. Note if the cheese on top is not melted you can cook a little longer or broil it for a minute or two to melt the cheese.
Enjoy!
