Unstuffed Shells Casserole

All the creamy, cheesy glory of stuffed shells – but you don’t have to stuff a thing.

To know a stuffed shell is to love it, because how could you not? A tender vessel of pasta that cups a luscious cheesy filling and is baked into a bubbly sauce… what’s not to like? Well, the actual process of stuffing the shells… that’s what. It’s a pain, no matter how you go about it. But, good news! With our Unstuffed Shells Casserole, you don’t have to go through any of that trouble and you still get the same comforting flavor you want out of the deal. Winner, winner, pasta dinner.

This recipe pairs shells with a ricotta, cream cheese, sour cream, and Parmesan filling and a meaty red sauce and bakes it all together. The nice thing about shells is that whether or not you take the time to stuff them by hand, the filling has a way of finding its way into the pasta and the bigger shells you use, the better that works out. The combination of cream cheese, ricotta, and sour cream might not seem terribly authentic for an Italian-inspired dish (it’s not) but it makes for a flavorful and creamy filling, just trust us.

And of course there’s a cheesy topping! What would a baked pasta dish be without it? In this case, we’ve got melty mozzarella which gets beautifully golden brown in the oven.

This is a situation where jarred marinara works just fine – you don’t need to stand over a stove all day simmering anything. We’ve just bumped up the heartiness with some ground beef, and the sauce goes on the bottom of the dish and also on the top so you get a nice layered effect with the shells and cheesy filling.
