Equipment

Ingredients

  • Gallon ziplock bag - make sure you have one
  • 12 oz. box jumbo shells you will only need 20-25 of them
  • 15 oz. whole milk ricotta cheese
  • 2 large eggs
  • 2 cups mozzarella cheese divided
  • ½ tsp. salt
  • ¼ tsp. black pepper
  • ½ tsp. garlic powder
  • 2 tsp. Italian seasoning
  • 2 Tbsp. parmesan cheese
  • 24 oz. Marinara sauce (I use Rao's Brand Marinara)
US Customary - Metric

Instructions

  • Cook the jumbo shells according to package directions for al dente pasta on the stove top. Don't overcook; you want to undercook the shells slightly. When they are finished rinse them in cold water and set aside.
  • In a large bowl, add the ricotta cheese, eggs, half of the mozzarella cheese, salt, pepper, garlic powder, Italian seasoning and parmesan cheese. Mix until combined.
  • Add half of the marinara to the slow cooker. Set aside for the moment.
  • Add this ricotta mixture to a gallon sized ziplock bag. Cut the corner of the ziplock bag. Squeeze the filling out of the corner of the bag into the shells - you may not need all the shells, I usually use about 20.
  • Add each stuffed shell to the crock pot on top of the marinara. You may have to stack a few if they don't fit.
  • Pour over the remaining marinara sauce.
  • Sprinkle with the remaining mozzarella cheese.
  • Cook on low for 3 hours. Serve and enjoy!

Notes

  • Place any remaining stuffed pasta shells and tomato sauce in an airtight container and keep in the fridge for up to 4 days.
  • You can add cooked ground beef or turkey to the marinara sauce if desired.
  • Drained spinach can be added to the ricotta mixture. (about 1 cup)
