Marinara Sauce

Sure, you can go for store-bought, but believe me when I say that you can taste the difference in the homemade version.

• Whole Tomatoes – 1 28-ounce can San Marzano tomatoes. This recipe calls for hand crushing the tomatoes. If you prefer to not do this, use crushed San Marzano tomatoes.
• Garlic – 6 cloves, lightly smashed
• Olive Oil – ¼ cup used to fry the garlic
• Herbs and Spices – Oregano, red chili flakes, kosher salt, sugar (to offset the bitterness from canned tomatoes)

Alfredo Sauce

Same applies to homemade alfredo sauce; it just tastes better when you make it.

• Egg – One large egg
• Heavy Cream – Serves as the creamy base for the sauce.
• Garlic – 3 tablespoons, minced
• Olive Oil – Needed to sauté garlic.
• Nutmeg – An essential ingredient added to white sauces.
• Cheese – Parmesan and pecorino romano thicken the sauce and aid in flavor.
• Spices– Season to taste with kosher salt and freshly cracked black pepper.

Breadcrumbs

Simple to make, these seasoned breadcrumbs add a beautiful hint of texture to the stuffed shells.

• Salted Butter – 1 tablespoons melted to coat breadcrumbs
• Seasonings – Italian seasoning and kosher salt
• Breadcrumbs – ¼ cup is all you need to give the top a nice dusting of crumbs.

How to Make Giant Cheese Stuffed Shells

There are a few steps to making these stuffed shells, but I promise the steps are straightforward:

Cook Giant Shells and Make the Breadcrumbs

1. Cook pasta. Bring a large pot of salted water to a boil. Add the shells and cook according to the package instructions until al dente. Drain the shells and run under cold water to stop the cooking. Set aside in a colander.
2. Make breadcrumbs. While shells are cooking, place all ingredients for breadcrumbs in a bowl and mix until combined. Next, spread on a prepared baking sheet and bake for 8-10 minutes or until golden brown. Set aside.

Make Marinara Sauce

1. Sauté garlic. Heat oil in a medium saucepan (one with tall sides) over medium heat, then add garlic once oil is hot, and lower heat to low. Sauté garlic for 4 minutes, careful to not the garlic brown too much. Once fragrant, carefully add tomatoes and increase heat to medium.
2. Add seasoning. Add dried oregano, red chili flakes, kosher salt, sugar, and reserved water, then stir. Cook until the sauce comes to a low boil.
3. Simmer. Lower heat to a simmer, then add basil and stir. Cook until sauce thickens and season to taste with more salt, if necessary. Remove from heat and set aside.

Make Alfredo Sauce

1. Make garlic butter. In a separate saucepan, heat oil in a medium saucepan over medium heat, then add garlic once oil is hot and lower heat to low. Sauté garlic for 4 minutes, careful to not the garlic brown as you want to infuse the oil with garlic flavor.
2. Add remaining ingredients. Add mixed egg yolk and creamy to garlic butter. Whisk until well combined. Add nutmeg, parmesan, pecorino romano and stir mixture until hot, but do not bring it to a boil. Once sauce is slightly thickened, season to taste with black pepper and salt.

Assemble the Stuffed Shells

1. Make stuffed shells filling. Add the egg, ricotta, mozzarella, parmesan, asiago, parsley, salt, black pepper, and garlic to a medium bowl and mix until well-combined. Transfer the filling to a quart-sized resealable bag and cut a ½-inch opening in the corner.
2. Assemble the stuffed shells. Spoon two-thirds of the marinara sauce into the bottom of a 9 x 13-inch baking dish. Pipe the cheese filling into each shell, then place in the baking dish. Top with the remaining marinara sauce, then finish with alfredo sauce. Cover the baking dish with foil.
3. Bake. Bake in a preheat 375°F oven.
4. Garnish and enjoy. Remove from the oven and top with toasted breadcrumbs and chopped fresh parsley. Leave to cool for 5 minutes before serving.

How to Store Leftovers

When stored correctly, giant cheese stuffed shells will last in the refrigerator for up to 5 days.

How to Reheat

Simply reheat shells in an oven-safe dish at 350°F for 12-15 minutes or until shells are warmed through.

Tips, Tricks and Customizations

• Short on Time? You can substitute homemade marinara and alfredo sauce for the bottled version, but I highly recommend you make the sauces yourself as they are both incredibly easy to make and taste significantly better than what you can purchase at the store.

• Don’t use pre-shredded cheese – I know you may be tempted to buy the pre-shredded four-cheese bags at the market, but I urge you to shred your own. Pre-shredded cheese contains anti-caking agents that prevent cheese from melting, and personally freshly shredded cheese always tastes better.
