Then baked with marinara sauce and additional cheese. The leftovers also make a delicious lunch!  If you have any vegetarians at your dinner table this is a perfect recipe.

How to Make Spinach and Ricotta Stuffed Shells

This recipe is relatively easy, but there are a few steps, so it is not a great recipe for a busy night. It is better reserved for the weekend or a day when you have a little extra time. 

Start by boiling the pasta shells in salted water until they are a firm al dente, about 7 minutes (remember they will continue to cook in the oven). Also preheat the oven to 350.

While the pasta is boiling make the ricotta and spinach filling for the shells. In a large mixing bowl combine  15oz ricotta cheese, 1/2 cup parmesan, 1 1/2 cups mozzarella, 1 egg, garlic powder, dried oregano, dried basil, salt, and red pepper flakes. Set aside.

Squeeze all the liquid out of the thawed spinach. See the note below on getting all the liquid out of your spinach! Crumble the dried out spinach into the cheese mixture and stir, making sure the spinach is dispersed throughout the filling.

Prepare a 9×13 baking dish by pouring half of the marinara across the bottom of the pan. Now fill the shells one at time by keeping the shell open with one hand while you spoon the ricotta mixture into the shell. Divide the ricotta and spinach mixture evenly between the shells. Lay the shells into the baking dish.

Cover the filled shells with the remaining marinara. Sprinkle with the remaining 1/2 cup mozzarella and 1/2 cup parmesan. 

Cover with foil and bake for 45 minutes. Remove the foil and bake for an additional 5 minutes.

Tips for Draining Thawed Spinach

To thaw the frozen spinach warm it through in the microwave. You will want to drain and squeeze ALL the water out of the spinach. This stuff is like a sponge! You cannot skip this step or your recipe will be a big watery mess. There are 2 great ways to drain the water out of the thawed spinach:

1. Put it in a fine mesh sieve and press it against the sides until you cannot get anymore water out.
2. Wrap the thawed spinach in a clean kitchen towel and wring the water out of the spinach until it stops leaking out.

After you get all the water out of the spinach it will be in a big clump. You will want to break it up and sprinkle it into the cheese mixture.
