Common Questions
How do I keep ravioli filling from getting watery?
Squeeze the spinach very dry and use ricotta that is not swimming. If your ricotta looks wet, drain it in a fine mesh sieve or cheesecloth for 30 to 60 minutes in the fridge. Thick filling seals better and cooks cleaner.
Do I need an egg in ricotta ravioli filling?
It helps. Egg acts like insurance, binding the ricotta so the filling stays cohesive once heated. If you are skipping egg, add an extra 2 to 3 tablespoons Parmesan and make sure everything is well drained.
Can I use frozen spinach?
Yes, and it is honestly convenient. Thaw completely, then squeeze it bone dry. For this recipe you want about 10 oz frozen spinach (thawed and squeezed) to equal roughly 12 to 16 oz fresh spinach once cooked and squeezed. If you prefer to be extra precise, measure the spinach after squeezing and aim for about 1 packed cup.
What is the best ricotta for ravioli filling?
Whole milk ricotta gives the best texture. If you can find a thicker style ricotta (often in a basket), even better. Avoid whipped ricotta here since it tends to be too loose.
How much filling per ravioli?
For standard 2 to 2 1/2 inch ravioli, aim for 1 to 1 1/2 teaspoons filling. Overfilling is the fastest route to blowouts.
What sauces go best with this filling?
Brown butter and sage, simple marinara, or a lemony cream sauce all work. If your sauce is bold and spicy, keep the filling seasoning on the gentler side so it does not fight back.
Help, I made it too salty or too lemony. Now what?
Easy fix. Stir in a few tablespoons more ricotta (or a small handful of drained, finely chopped spinach) to calm things down. If it gets too loose, add a little more Parmesan to bring it back to a thick, scoopable texture.
Is piping really worth it?
If you are making more than a handful, yes. A piping bag (or zip top bag) keeps the edges cleaner, which means better seals and fewer blowouts. Spooning works too, just wipe any filling off the dough before sealing.
