Unstuffed Shells Casserole is a delicious take on stuffed shells. This delicious casserole is full of cheese, spaghetti sauce, and great Italian flavor. It’s always a winner!
Do you love stuffed shells but hate the work of actually stuffing them? If that’s you, welcome to the club! Stuffed shells are so good, but it can be so tedious to fill them up. That’s why we came up with this delicious variation.
A New Take on a Classic
This unstuffed shells casserole takes everything we love about the classic stuffed shells recipe and makes it so much easier. Rather than standing around and spooning cheese filling into noodle after noodle, we thought to ourselves, “What if we just don’t stuff them?”
That’s right. This recipe takes all the delicious ingredients of classic stuffed shells and, just like the name says, unstuffs them! It saves so much time to simply cook it all together, and it tastes so good. It’s a wonderful twist on the classic.
A Lasagna-Adjacent Dish
If you take a look at this recipe, you’ll quickly see that unstuffed shells casserole has essentially all the ingredients found in lasagna but made with a different type of noodle.
That makes sense if you think about it because what are stuffed shells if not lasagna made with shell noodles instead of lasagna noodles? After all, the filling for stuffed shells is the same as the ricotta layer you put in lasagna. They both use spaghetti sauce. They both use shredded cheese.
So this unstuffed shells casserole is really just taking everything about lasagna or stuffed shells and sort of mashing it all together. You get all the great taste you love about stuffed shells or lasagna but with a fraction of the work.

Unstuffed Shell Casserole Variations
One of the great things about any recipe like this, whether it’s our unstuffed shells casserole, stuffed shells, or lasagna is that you can switch things up whenever the recipe is feeling stale.
There are a variety of ways you can change up this recipe to make it your own.
Change the Noodles
While we used the classic shell noodles for our unstuffed shell casserole, you can use any sort of pasta shape you like.
Our one caveat is that spaghetti and other long noodles won’t work well in this recipe, as it will all become one big mass. Some great shells to try include:
- Elbow Macaroni
Change the Meat
You probably immediately noticed that we used ham in our unstuffed shells casserole rather than ground beef. While most people think of ground meat in a recipe like this, ham is a traditional ingredient in Italian pasta, as well.
If you want, you can change up the meat used in the recipe to change the flavor of this casserole easily. Great meat variations include:
- Ground Beef
- Crumbled Crispy Bacon
- Ground Chicken
- Ground Turkey
- Ground Italian Sausage
- Ground Pork
Change the Sauce
Any sauce at all will work well with this recipe. We used a tomato-based, jarred spaghetti sauce to stay true to the red sauce found with stuffed shells, but you could easily go with a creamy sauce or a homemade sauce, as well.
The sky’s the limit with sauces because pretty much every sauce out there goes with meat, noodles, and cheese. Here are some ideas for different sauces.
- Homemade Spaghetti Sauce
- Marinara Sauce
- Chunky Jarred Sauce
- Veggie-Filled Jarred Sauce
- Vodka Sauce
- Alfredo Sauce
- Any Red Sauce
- Any White Sauce
Serving Unstuffed Shells Casserole
This unstuffed shells casserole is an entire meal in and of itself. It’s hearty and delicious. It’s also a heavy dish, so you want to serve it on its own. The only side we recommend is a nice salad if you like.
Storing Unstuffed Shells
You can store this unstuffed shells casserole in the refrigerator for about four days in an air-tight container.
For longer storage or for meal prep, you can store this casserole either cooked or uncooked in the freezer for up to three months. It’s perfectly okay to store it in the baking dish.
Just remember to cover the dish tightly and allow it to defrost in the refrigerator. Never try to cook the lasagna from frozen. It won’t cook correctly, and the drastic change in temperature could cause your baking dish to crack.
