Preparing Your Ingredients for Success
Essential Ingredients for Ronzoni Stuffed Shells
To make delicious ronzoni recipes stuffed shells, you’ll need a mix of basic and flavorful ingredients. Start with a 12 oz box of jumbo shells—this typically includes around 30-40 shells, enough to fill a standard baking dish. For the filling, gather the following:
- 15 oz ricotta cheese: Smooth and creamy for a classic base.
- 2 cups shredded mozzarella cheese: Adds gooey, stretchy texture.
- 1/2 cup grated parmesan cheese: Offers a rich, nutty flavor.
- 1 large egg: Helps bind the filling.
- 2 cups marinara sauce: Choose your favorite brand or make it at home.
- 1 tsp garlic powder: Enhances the filling’s flavor.
- 1 tbsp dried Italian seasoning: A blend of oregano, basil, and thyme adds a classic Italian touch.
- Salt and pepper: Season to taste.
Optional ingredients for extra flair include chopped spinach, cooked and crumbled Italian sausage, or sautéed mushrooms.
Prepping Your Filling: Cheese, Vegetables, or Protein
To make the filling, combine ricotta, mozzarella, parmesan, egg, garlic powder, Italian seasoning, salt, and pepper in a large bowl. Mix until smooth and creamy.
For a veggie twist, mix in 1 cup of chopped spinach (fresh or frozen and drained). Prefer a meatier option? Stir in 1 cup of cooked Italian sausage or shredded chicken.
Set the filling aside, and prepare your sauce by spreading 1 cup of marinara on the bottom of a greased baking dish. This layer prevents the shells from sticking and keeps them moist during baking.

Step-by-Step Guide to Perfectly Cooked Jumbo Shells
Cooking Ronzoni Jumbo Shells to Al Dente Perfection
To cook the jumbo shells, fill a large pot with water and bring it to a boil. Add 1 tbsp of salt to the water—it seasons the pasta as it cooks. Gently add the shells, stirring occasionally to prevent them from sticking. Cook for 9-10 minutes, or until they’re al dente. You want them firm but pliable enough for stuffing.
Drain the shells in a colander and rinse them with cool water to stop the cooking process. Lay them out on a clean towel or baking sheet to prevent sticking. This step ensures the shells stay intact and ready to be filled.
Stuffing and Baking the Shells
- Fill the shells: Using a spoon or piping bag, stuff each shell with 1-2 tablespoons of your prepared filling. Be generous but avoid overfilling to keep the shells intact.
- Assemble the dish: Place the stuffed shells seam-side up in the prepared baking dish. Pour the remaining marinara sauce evenly over the shells, ensuring each one is coated.
- Top with cheese: Sprinkle an additional cup of shredded mozzarella over the saucy shells for that golden, bubbly finish.
- Bake to perfection: Cover the dish with foil and bake at 375°F (190°C) for 25 minutes. Then, uncover and bake for another 10-15 minutes, or until the cheese is melted and slightly browned.
Serve your ronzoni recipes stuffed shells hot, garnished with fresh basil or parsley if desired.

Baking Tips for Perfectly Bubbly Stuffed Shells
Setting the Right Temperature and Timing
Baking stuffed shells to perfection is easier than you think. Always preheat your oven to 375°F (190°C) before starting.

Adding a Cheesy Topping for Extra Appeal
Cheese lovers rejoice! To achieve a beautifully gooey top layer, sprinkle an extra cup of shredded mozzarella or a mix of mozzarella and parmesan over your shells before baking. If you’re feeling adventurous, add a handful of breadcrumbs for a crispy, cheesy crust.
Serve your ronzoni recipes stuffed shells straight from the oven, but let them rest for a few minutes to make serving easier and avoid burns.

Serving Suggestions and Pairings
Ideal Side Dishes for Ronzoni Stuffed Shells
