Cheesy stuffed shells on a plate


When I think of comfort food, two things come to mind: a warm bowl of soup and a hearty casserole or baked pasta. The Italians really know how to make their comfort food well, and this Stuffed Shells with cheese recipe is no exception!

It's extremely rich and filling, thanks to the cheese and pasta, and it's loaded with flavor! Fresh basil, marinara sauce, spinach, garlic, and herbs all come together to make the classic Italian flavors that you find in so many of their pasta and pizza dishes.

Plus, if you are someone who loves cheese, this is definitely the recipe for you. I loaded this stuffed shells recipe with four cheeses: ricotta, cream cheese, mozzarella, and parmesan so that it is incredibly satisfying!

The pasta shells used in this stuffed shells with spinach recipe are known in Italian as "conchiglie" which means "shells" or "seashells" because they look a lot like conch shells that you'd find at the seaside. They are made in different sizes as well: conchigliette is a small shell shape, and conchiglioni is the larger shell for stuffing that we use here.

To prep them, you just have to cook them until they are al dente, as you would any normal pasta. While they boil, throw together the filling, then drain the shells and stuff them before arranging in a casserole dish and covering with sauce and cheese. Easy peasy!

Ingredients for Stuffed Shells

  • Cheese: Four types of cheeses are used in this stuffed shells recipe: ricotta and cream cheese for creaminess, mozzarella to add a gooey texture, and parmesan for some cheesy sharpness.
  • Fresh basil: Fresh basil is one of my all-time favorite ingredients to put in classic Italian recipes like pasta and pizza. It adds such an aromatic flavor, and you don't need much to make an impact.
  • Italian seasoning: In Italian seasoning, you'll find a blend of classic Italian herbs like basil, marjoram, oregano, rosemary, and thyme. They add tons of flavor as well!
  • Salt & pepper: These key culinary ingredients bring out all of the other flavors in this stuffed shell dish.
  • Egg: An egg helps binds the filling with all of the cheeses together, and also raises it slightly when cooking.
  • Garlic powder: We're making Italian, you knew garlic would be in here somewhere! I opted for garlic powder this time, but a clove of fresh garlic, minced, would be fine.
  • Fresh spinach: These leafy greens are cooked until wilted and added to the cheese mixture. Spinach and ricotta go so well together! You could use frozen spinach that has been thawed and had a lot of the water squeezed out.
  • Marinara sauce: I used storebought this time to make this stuffed shells recipe quick and easy (Rao's is my favorite brand), but you could always make homemade marinara sauce instead!
  • Fresh parsley: To garnish at the end! Completely optional, but I love the added freshness and bit of color it brings.

How to store this pasta bake

Store these stuffed pasta shells in an airtight container for up to 5 days in the fridge. You can also prep and refrigerate it a day or two before, and then cook it when you're ready. Just make sure you don't over-cook the pasta shells when you boil them, so they keep their shell-shape. Reheat it in the oven or microwave until it's piping hot.

  1. I was really looking for a recipe that used cream cheese bc I thought why not but I'm not an adventurous cook. I got all the ingredients, I think, but then my husband died. I thought you might be good source but I see nothing about the cream cheese.
