My Spinach and Mushroom Stuffed Shells recipe have three kinds of cheese that are melted and gooey. The stuffed shells are then covered in a rich, homemade Marinara sauce and more cheese. This spinach and mushroom filling works great with any pasta shape meant to be stuffed and baked. The pasta shape in the photos is named ‘lumaconi’, but a manicotti or conchiglie shape works great as well.
I break one major pasta cooking rule; I rinse the pasta shells once they are finished boiling, something that is a strict, cooking no-no. Normally you want the pasta to still have that starchy coating. The pasta starch helps grab onto the sauce and gives you that great flavor and texture. However, in order to work with the shells and stuff them you need to do two things:
1) The pasta shells need to cool down a little so you don’t burn your fingers.
2) They can’t be stuck together. If the starch on the pasta is allowed to stay on the shells, they will stick together in one big clump and you’ll never be able to work with them without tearing and destroying most of them. By rinsing, you stop them from sticking and all is well in the world, haha.
This is the same Marinara sauce recipe that I’ve used in several other recipes and it is perfect for stuffed shells. The recipe is quick and easy to make, and it costs less than half of what I spend on a jar of sauce. So, for five minutes’ worth of work, you get a sauce that is infinitely better than any sauce you get in a jar.
I use my Homemade Ricotta Cheese for my spinach and mushroom stuffed shells. Store-bought ricotta cheese is fine. However, Homemade Ricotta Cheese is about a thousand times better than store-bought. Some cheeses are meant to be eaten right away as soon as you make it and Ricotta is one of them. Anytime I see a prepackaged ‘fresh’ type of cheese that has a really long expiration date on it, it makes turn my nose up. lol, I know how dull and flavorless it’s going to taste.
