Tips to Consider When Cooking Stuffed Shells

Stuffed shells are popular for their taste, wholesomeness, and ease when cooking but that can only be achieved when you know what you’re doing, so here are some great tips that are sure to support you when you’re making stuffed shells.

Make sure you don’t fully cook your pasta before baking; the pasta would continue cooking when you place them into the oven, so make sure you undercook them by one or two minutes or half the cooking time stated on the package before baking them. If you overcook the pasta shells they would be too soft and hard to stuff plus they would tear easily when baked.

Grate your bowl of cheese; rather than buying bags of grated cheese from the grocery stores, it is best to grate them at home because that way you’re sure they are fresh and are free from preservatives or anti-caking agents which would prevent them from melting properly.

Cook additional 3-4 pasta; if you plan to make 20 stuffed shells make sure to cook 23 or 24 shells because some of them may rip during the cooking process.

Choose the right cheese that suits your preferences; the stuffed shells recipe comes with the classic three cheese stuffing of ricotta cheese, freshly grated parmesan cheese, and whole milk mozzarella cheese but if you’re trying to cut back on the calories then use part-skim milk ricotta or mozzarella cheese.

Try using good quality jarred marinara sauce; you could either make your sauce at home or buy it from the grocery store, if you’ll be buying marinara sauce from the grocery store, you should pick high-quality ones like Newman’s, Classico, or you can just stick to your favorite brand.

Use cold water to prevent the pasta from sticking together; after undercooking your pasta drain it from the hot water and add some cold water to it for about 30-40 seconds, this would halt the cooking process and prevent the pasta from sticking to each other.

You could refrigerate the stuffed shell before baking; you could always refrigerate the unbaked stuffed shells until you’re ready to eat them just cover the baking dish with a foil.

However,  you may need additional time to bake the stuffed shells since you’ll be baking them from a cold state and not at room temperature.

Also, if you end up making too many stuffed shells you can refrigerate these cooked stuffed shells for 2-5 days.

Feel free to add or remove ingredients to suit your preference; stuffed shells are known for the basic ingredients like pasta, sauce, cheese, and additional spices or herbs but this doesn’t mean you must stick to the particular ingredient types used especially when these ingredients do not suit you.

I’ll explain, you could use other cheese types instead of the common three like provolone, cream cheese, fontina, small curd cottage cheese, asiago, or romano.

You could use creamy Alfredo sauce, hearty bolognese style meat sauce, etc to substitute marinara sauce.

Also, you could add extra stuffings to your cheese like some protein (some shredded beef or chicken), spices like rosemary, oregano, thyme, etc, and vegetables of your choice like onions, peppers, zucchini, spinach, etc.

Place the stuffed shells seam up to prevent excess leakage; when baking stuffed shells place them with the open area facing up not down so the stuffings would not melt and leak out of the shell.
