Cheese Ravioli Filling

Introduction

This simple cheese filling comes together in one bowl and delivers the creamy, savory center that makes homemade ravioli worth the effort. The combination of ricotta, Parmigiano Reggiano, and a single egg creates a filling that’s rich enough to stand on its own but light enough not to overwhelm a delicate pasta sheet. Mix it while your dough rests so everything is ready when you’re prepared to fill and seal.

Recipe Details

• Prep Time: 5 minutes
• Cook Time: 0 minutes
• Total Time: 5 minutes
• Servings: Fills approximately 24–30 ravioli

Ingredients

• 1½ cups ricotta or cottage cheese
• ¾ cup freshly-grated Parmigiano Reggiano

• 1 egg
• 1½ tsp salt

Instructions

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

Variations

Use all ricotta or all cottage cheese: Ricotta produces a slightly lighter, airier filling; cottage cheese yields a denser, tangier result. Either works; choose based on your texture preference.

Add fresh herbs: Stir in 1 tablespoon of finely-chopped parsley, basil, or chives before filling. This adds brightness without altering the structure.

Increase the Parmigiano Reggiano to 1 cup: This deepens the savory note and makes the filling slightly firmer. Best if you like a more pronounced cheese flavor.

Include a pinch of nutmeg: A small grating of fresh nutmeg (about ⅛ teaspoon) is a classic pairing with ricotta cheese and adds subtle warmth.

Mix in 2 tablespoons of finely-chopped spinach: Drain any excess moisture first. This adds color, nutrition, and a mild earthiness without changing the filling’s binding properties.

Tips for Success

Grate the Parmigiano Reggiano fresh: Pre-grated cheese contains anti-caking agents that can make the filling slightly grainy. A box grater or microplane takes two minutes and transforms the texture.

Don’t overmix once you add the egg: Stir just until combined. Overworking develops gluten in the ricotta and can make the filling dense or rubbery when cooked.

Taste for salt before filling: Because the filling is raw, you can adjust seasoning now rather than after cooking. A small spoonful on your finger lets you check the balance.

Use the filling within a few hours: If you’re not filling ravioli immediately, cover the bowl with plastic wrap and refrigerate. The egg begins to set over time, making the filling stiffer and harder to work with.

Fill ravioli with a small spoon or piping bag: A heaping teaspoon per ravioli prevents overstuffing, which causes bursting during cooking. A small piping bag gives you the most control.

Storage and Reheating

In the refrigerator: Store the unfilled mixture in an airtight container for up to 2 days. The raw egg means it should not be kept longer. Once you’ve filled and sealed the ravioli, refrigerate them on a parchment-lined tray (uncovered) for up to 1 day, then transfer to a freezer bag if keeping longer.

In the freezer: Freeze filled ravioli on a parchment-lined tray for at least 2 hours before transferring to a freezer bag. They keep for up to 3 months. Cook frozen ravioli directly from the freezer—add 1–2 minutes to the cooking time and they’ll cook through without thawing.

FAQ

Can I use egg substitute or skip the egg altogether?

The egg binds the filling and gives it structure so it doesn’t fall apart during cooking. Skipping it may result in a loose filling that leaks into the pasta water. If you must avoid egg, try binding with 1 tablespoon of heavy cream or a tablespoon of finely-grated hard cheese instead, but the result will be slightly different.

What’s the difference between ricotta and cottage cheese for this filling?

Ricotta is smoother and creamier; cottage cheese has visible curds and a tangier taste. Both work. Ricotta produces a more refined texture in the finished ravioli, while cottage cheese gives a coarser, more rustic bite.

Should I drain excess liquid from the ricotta or cottage cheese?

Yes, if your ricotta or cottage cheese is very wet. Spoon it into a fine-mesh strainer lined with cheesecloth and let it sit for 10–15 minutes. Excess moisture dilutes the filling and can make the ravioli soggy.

How much filling should go into each ravioli?

A heaping teaspoon (about ½ tablespoon) is the standard. Too little looks sparse; too much causes the pasta to burst at the seams during boiling. A small spoon or piping bag helps you be consistent.
