Cheese Ravioli Filling

Introduction

This simple cheese filling combines ricotta or cottage cheese with aged Parmigiano Reggiano, egg, and minimal seasoning—the core of a classic ravioli that lets the cheese shine. Because the filling is mixed ahead, you can roll your dough and assemble all your ravioli without pausing, making assembly line work efficient. The texture is creamy and rich, holding together perfectly when sealed and cooked.

Recipe Details

• Prep Time: 5 minutes
• Cook Time: 0 minutes (filling only; ravioli cooks separately)
• Total Time: 5 minutes
• Servings: Fills approximately 24–30 ravioli (3–4 servings as a main course)

Ingredients

• 1½ cups ricotta or cottage cheese
• ¾ cup freshly-grated Parmigiano Reggiano
• 2 tsp finely-chopped onion
• 1 egg
• 1½ tsp salt

Instructions

1. Stir all the ingredients together in a bowl.
2. Set aside while you roll the dough.

Variations

Herbed filling: Add 2 tablespoons finely chopped fresh parsley and 1 teaspoon dried oregano to the mixture. The herbs brighten the cheese and add earthiness without overpowering the Parmigiano.

Nutmeg warmth: Stir in ⅛ teaspoon freshly grated nutmeg. A small amount adds subtle sweetness and depth that’s traditional in Italian cheese fillings.

Spinach-enriched: Fold in 3–4 tablespoons thawed, drained frozen spinach (or finely chopped fresh spinach, squeezed very dry). This adds moisture and iron while keeping the filling spreadable.

Creamy texture: Replace the egg with 3 tablespoons heavy cream or crème fraîche. The filling becomes looser and richer, easier to pipe into ravioli molds.

Cheese depth: Swap half the Parmigiano for aged Pecorino Romano (¼ cup each). Romano is sharper and saltier, intensifying the cheese flavor.

Tips for Success

Use fresh ricotta if possible. Grocery store ricotta can be watery; drain it in a fine-mesh strainer for 10 minutes before mixing to prevent a soggy filling.

Grate Parmigiano Reggiano by hand. Pre-grated cheese contains cellulose and doesn’t incorporate smoothly; hand-grated creates a cohesive, creamy texture.

Mix gently but thoroughly. Stir until the egg is fully dispersed and the filling is even in color—underworked filling will tear when sealed; overworked filling becomes dense.

Taste and adjust salt before assembling. A small pinch of the filling on your tongue will tell you if it needs more seasoning, since the pasta dough will be unsalted and neutral.

Keep the filling covered. If you’re not filling ravioli immediately, press plastic wrap directly onto the surface to prevent a skin from forming.

Storage and Reheating

Refrigerator: Store in an airtight container for up to 2 days. The filling itself does not reheat—use it to assemble and cook fresh ravioli within that window.

Assembled ravioli (uncooked): Lay filled ravioli on a parchment-lined tray and freeze for at least 2 hours, then transfer to a freezer bag for up to 3 months. Cook directly from frozen, adding 1–2 minutes to the boiling time.

Cooked ravioli: Store leftovers in an airtight container in the refrigerator for 3 days. Reheat gently on the stovetop in simmering broth or sauce, or in a 300°F oven covered with foil until warmed through (5–7 minutes).

FAQ

Can I use store-bought ricotta that’s slightly watery?

Yes, but drain it first. Place it in a fine-mesh strainer lined with cheesecloth for 15 minutes to remove excess moisture, which prevents a filling that leaks from sealed ravioli during cooking.

What if I don’t have an egg?

You can use 3 tablespoons of heavy cream or whole milk instead. The egg binds and enriches; cream provides moisture and fat. The filling will be slightly looser, so adjust your filling quantity per ravioli accordingly.

Can I make this filling a day ahead?

Yes. Cover and refrigerate up to 2 days. The flavors actually meld and improve slightly overnight. Stir briefly before filling ravioli.

Should I cook the filling separately, or only after sealing it in ravioli?

Only cook it after sealing. The filling is raw and relies on the heat transmitted through the ravioli dough and the boiling water to set and become safe to eat.
