A Giant Cheese Stuffed Shells Recipe filled with a delicious mix of Italian cheeses, nestled in marinara sauce and topped with creamy Alfredo with an optional crunchy breadcrumb topping! A copycat Olive Garden stuffed shells recipe.
Cook Pasta: In a large pot, bring to boil salted water (usually about 2 tablespoons of kosher salt) and cook pasta according to package directions, stirring occasionally to keep shells from sticking.
Reserve ½ cup of pasta water in case you need to thin your alfredo sauce. Then drain shells in a strainer and then prepare to stuff.
Cheese Filling: In a large mixing bowl, lightly beat the egg, then add ricotta cheese, mozzarella, provolone, parmesan cheese, salt, pepper, garlic, chopped basil, oregano, and parsley and mix until combined.
Stuff Shells: Using a tablespoon or a small cookie scoop, gently grab cooked shell and using the scoop or spoon stuff the shell, try not to overstuff. Set on a cookie sheet until all shells are filled.
Bake Stuffed Shells: Place 2-3 cups of marinara sauce into the bottom of 9x13 inch casserole dish. Use, more if you like them really saucy, I like to reserve some for serving. Carefully nestle stuffed shells into the sauce, in a single layer. Sprinkle the remaining cheese over the tops.
Cover with oil sprayed foil and bake for 30-40 minutes until hot and bubbly, if desired, broil 2-4 minutes for golden cheese.
If Making - Make Alfredo Sauce while shells are baking
In a medium skillet or saucepan, add butter and melt, tossing the garlic in at the last minute, stirring constantly until fragrant.
Over medium heat, add the heavy cream to the garlic butter mixture, stirring to combine, and bring to low simmer. Reduce heat to medium-low then stir in nutmeg (garlic powder, if not using fresh garlic), nutmeg, salt and pepper.
Stir in grated parmesan cheese until melted and the sauce is thickened. Garnish with chopped parsley, take a taste and if needed stir in a little more salt.
Optional - Make Toasted Breadcumbs
In a small skillet, over medium heat, melt butter and add seasoned breadcrumbs, stirring to coat, then stirring regularly. Watch closely as it can go from toasted to burned quickly.
To serve
Drizzle a little Alfredo sauce over the tops of the baked shells, and sprinkle with some seasoned breadcrumbs and some chopped fresh parsley. I prefer to let people add their own Alfredo sauce, so will serve the Alfredo and the breadcrumbs on the side.
Notes
I try and add as much detail as I can to the recipe card, but there is much more information in the post. A quality store-bought Alfredo sauce may be used, but homemade Alfredo sauce takes minutes to make, and it’s SO worth it. Store-bought marinara may also be used. Amp up the flavor by sautéing 2 cloves minced garlic in 1 tablespoon of hot olive oil, then add jarred marinara. Storage
