Brown ground beef with diced onion over medium heat. Remove from heat and let mixture cool slightly.
In large bowl, mix ricotta, 2 cups mozzarella cheese, ½ cup Parmesan cheese, garlic, salt and pepper. Stir in meat mixture and set aside.
Bring a large pot of salted water to a boil. Add the stuffed shells and cook until softened but still firm to the bite, approximately 9 minutes, stirring occasionally.
While pasta is boiling, add 1 tablespoon of olive oil to large jelly roll pan.
Once pasta has cooked for 9 minutes, remove with slotted spoon to prepared jelly roll pan and let cool.
Preheat oven to 350°F. Spray baking pans with non-stick cooking spray. Spread approximately half cup of marinara sauce into the bottom of each of the baking pans.
Fill shells with the cheese-meat mixture and arrange in prepared baking pans in single layer.
Spread remaining marinara sauce over the top of stuffed shells. Sprinkle with remaining 1.5 cups shredded mozzarella cheese and ½ cup Parmesan cheese.
Shells can be baked right away, covered and stored in the refrigerator for up to 24 hours, or frozen for up to 3 months.
Bake stuffed shells uncovered for approximately 30-35 minutes, until sauce bubbles. Remove from oven and let stand for 5 minutes. Add 10 minutes of cooking time if stuffed shells have been in the refrigerator prior to cooking.
To Freeze
Use an airtight container to prevent freezer burn or double-wrap baking pans with aluminum foil. Label with date and cooking directions before placing in freezer. Place baking bans in level position within freezer. Use within three months.
When ready to prepare, thaw in the refrigerator overnight. Bake uncovered in 350°F oven for approximately 35-45 minutes, until sauce bubbles. Remove from oven and let stand for 5 minutes.
