Easy Unstuffed Shells Casserole

Is there anything better than cheesy carbs? Pure comfort food at its finest. And today’s UNSTUFFED Shells recipe fits the bill. You have an easy, savory meat sauce, layered with cheesy pasta shells, and topped with more sauce and MORE cheese! Are you interested yet?

I am going to assume you are familiar with Italian Stuffed Shells. If not, no worries, they are are seasoned ricotta cheese mixture stuffed inside large pasta shells, topped with sauce, and baked! While they are fairly easy to make, I love the idea of a “dump and go” kind of casserole where everything is mixed together and every bit is perfection!

This recipe combines all the flavors and ingredients of the classic, without the fuss of stuffing the individual shells.

Unstuffed Shells Ingredients:

  • Olive oil
  • Diced onion
  • Lean ground beef. You can use ground turkey instead if you would like!
  • Minced garlic
  • Marinara sauce. You can use any brand you prefer, and even switch up the flavor of sauce if you would like as well.
  • Medium shell pasta. Honestly you can use pretty much any small cut pasta in this recipe, but since it’s called Unstuffed Shells, I use shell pasta!
  • Cream cheese. You can use low fat cream cheese if you would like.
  • Ricotta cheese. You can use full fat or part skim ricotta.
  • Parmesan cheese. Use fresh grated and not the powdered kind. It’s just better!
  • Egg
  • Italian seasoning. if you don’t have Italian seasoning on hand, you can use an equal mixture of basil, marjoram, oregano, rosemary, and thyme…or really any combination of these. If you are missing one or two of these alternatives it really won’t make a huge difference.
  • Kosher salt
  • Fresh ground black pepper
  • Crushed red pepper
  • Low moisture mozzarella cheese

Make This Ahead:

This is a great make-ahead dish if you are planning ahead, or gifting dinner to a friend. You simply follow all the instructions up until the point of baking the casserole. Just pop it in the refrigerator overnight and bake it the next day. You might need to add a few minutes of bake time if you are baking from cold, but everything is cooked, so you just want to make sure it’s warmed through.

Can You Freeze Unstuffed Shells?

Absolutely! This is a great dish to freeze ahead for later. again, all you do is prep it up until the point of baking. Make sure it’s covered airtight and freeze it for up to 30 days.

I prefer thawing it out in the refrigerator overnight before baking.

  1. Just assembled this tonight to cook for supper. Made another one for the freezer. Have you ever tried freezing? Hoping it stays good!

    1. This could easily be frozen! You could thaw it out before baking or bake it frozen (covered) and for about an hour.

  2. Enjoyed this easy casserole. I over looked purchasing mozzarella but I had fontina cheese on hand
    It worked out well.
    Great recipe






  3. I wanted stuffed shells but didn’t feel like stuffing them so I came across your recipe. Oh my god, it’s actually so much better than stuffed shells that I’m making it that way from now on. If I could give more than 5 stars, I would.

    My teenage daughter made this for dinner last night. It was easy to make, and really yummy!






  5. A friend in college always got super excited when the dining hall served stuffed shells. I never understood her love of them, but this recipe is really good. I put in two more cloves of garlic and a 1/2 cup more mozzarella cheese.
