Ingredients You’ll Need

Here’s what you’ll need for these delicious stuffed shells:

  • Jumbo pasta shells –  You should cook a few extra shells just in case some break while cooking or stuffing the shells.
  • Baby spinach – We use fresh bagged spinach instead of frozen or canned.
  • Cheeses – You’ll need whole milk ricotta, shredded mozzarella cheese,  and Parmesan cheese.
  • Seasonings – For the right flavor, you’ll need Italian seasoning, onion powder, garlic powder, salt, and black pepper.
  • Egg – This helps hold the filling together.
  • Marinara sauce – You can use your favorite recipe or jar.

Instructions

Follow these instructions for best results.

Step 1 – Prep the pasta. Before getting started, preheat the oven to 375 degrees F. 

As the oven heats, cook the jumbo shells according to the instructions on the back of the box.

Once cooked, drain the pasta and run under cold water to stop the cooking process. Let the pasta sit in the strainer to cool while you ready the rest of the ingredients. 

Step 2 – Prepare the spinach. As the pasta cools, place the baby spinach in a microwave safe bowl with 3 tablespoons of water. Wet a paper towel and place the wet paper towel on top of the spinach. Microwave for 2 to 3 minutes or until fully cooked.

Carefully, pour the cooked spinach into a strainer and let the water drain out until it has cooled completely. Once it is cooled, give it a few good squeezes to get as much excess water out as possible. This will help prevent the cheese filling from getting soupy.

Finally, finely chop the spinach up and set aside.

Step 3  – Make the stuffing. In a large bowl, combine the ricotta, 2 ounces of shredded mozzarella, Parmesan cheese, Italian seasoning, onion powder, garlic powder, salt, pepper, cooked spinach,and egg. 

Stir together until the ingredients are well mixed.

Step 4 – Stuff and bake. Fill each of the shells with approximately 2 tablespoons of filling. Next, pour 1 cup of sauce in the bottom of a 9×13 inch casserole dish.

When the layer of sauce is down, add the stuffed shells to the dish and then top with remaining sauce. Finally, sprinkle with the remaining 4 ounces of mozzarella and then bake for 25 to 35 minutes or until warmed through.

Serve immediately fresh from the oven.

Can I Use Frozen Spinach in Ricotta Stuffed Shells? 

Yes, you can use frozen spinach if you want to. To use frozen, thaw it completely and then squeeze out as much water as possible. You want to make sure they are pretty dry to avoid making the stuffing too loose.

How to Make it Ahead of Time 

If you want to make the recipe ahead of time, follow instructions through stuffing and assembling the shells. Place the assembled shells in an airtight container or cover them with plastic wrap. You can refrigerate them for up to 3 days.

To cook, bake them at 375 degrees F for 35 to 45 minutes. Cover with foil for the first 25 minutes and then remove the foil and continue baking until warmed through.
