Cooking pasta is simple, but getting it just right comes down to a few key details. The amount of water and salt, how long you cook it, and how you finish it all make a noticeable difference. This guide walks you through how to cook pasta perfectly at home, with clear ratios and practical techniques you can trust.
Pasta is what I cook most, and over the years I’ve tested countless methods, ratios, and techniques to get consistently great results. In this post, I’ve pulled together the exact water and salt ratios, timing cues, and finishing techniques I use every time I cook pasta at home.
From warming plates to finishing pasta directly in the sauce, these small details make a big difference. Happy cooking!

How to cook pasta perfectly (quick guide)
- Use 2.5 quarts (2.5 liters) of water per 400g pasta.
- Salt generously. 1.5 tablespoons salt per 400g pasta.
- Undercook dried pasta by 1 minute so it finishes perfectly in the sauce.
- Reserve a cup of pasta water before draining.
- Finish pasta in the sauce, not just topped with it.
Amount of pasta per person
- Dried pasta - 100 grams per person
- Fresh pasta - 150 grams per person
I always weigh my pasta portions. It might seem unnecessary, but it’s the easiest way to get the right sauce to pasta ratio and avoid any guesswork.
Dried pasta absorbs more water as it cooks and increases in weight significantly, which is why you need less of it than fresh pasta.
How much water to boil pasta in
For most pasta dishes, use 2.5 quarts (2.5 liters) of water for 400 grams of pasta. This is enough water for the pasta to cook properly while keeping the cooking water nice and starchy.
Pasta releases starch as it cooks, and that starchy water is incredibly useful for loosening and emulsifying sauces. Using too much water dilutes the starch, making it far less effective. Less water means more concentrated pasta water and a better sauce.
If you prefer to cook a full pound (450g) of pasta at once, 3 quarts of water works well.
How much salt to add to pasta cooking water
For 400 grams of pasta cooked in 2.5 quarts (2.5 liters) of water, use 1.5 tablespoons of salt. This seasons the pasta itself, not just the sauce, and makes a huge difference to the final dish.
The exact amount can vary slightly depending on the type of salt you use. I use basic iodized table salt for pasta water. If you’re using kosher salt, you may need a little more, as it’s less salty by volume, start with the same amount and adjust next time if needed.
Your pasta water should taste well seasoned. If it tastes bland, the pasta will be too.
Salting the pasta water is the only chance to season the pasta itself. Pasta is made from flour and eggs or flour and water, so without salt it’s completely bland. Even the best sauce can’t fully compensate for under-seasoned pasta.

How long do you boil pasta for?
As a general rule, cook dried pasta 1 minute less than the package instructions. This gives you room to finish cooking the pasta gently in the sauce, without it becoming overcooked.
Because pasta shapes vary, the best way to tell when it’s ready is to taste it. You’re looking for pasta that’s just tender with a slight bite, so it finishes perfectly once it’s added to the sauce.
What about fresh pasta?
Fresh pasta cooks a lot quicker than dried pasta. Cooking time depends on the thickness and shape, so it’s best to start checking it early. Most fresh pasta should be checked after 2 minutes.
Here are some general guides:
- Fresh pappardelle: 2–3 minutes
- Fresh ravioli: 5–6 minutes
- Fresh orecchiette: 3–4 minutes
Fresh pasta is ready when it’s tender but still holds its shape. As with dried pasta, it’s best finished gently in the sauce rather than cooked until completely done in the water.
If you’d like to make your own, start with my Easy Homemade Pasta Dough, then explore my pasta shape guides to choose a shape.
How to boil pasta (step by step)
1. Bring the water to a rolling boil over high heat, then add the salt.
2. Add the pasta to the salted water. If cooking spaghetti, drop it in and wait about 30 seconds before easing it down into the water. Don’t break it.
3. Cook the pasta, undercooking dried pasta by about 1 minute from the package instructions.
4. Just before transferring pasta to sauce or draining, reserve a cup of cooking water.
5. Transfer the cooked pasta directly from the water into the sauce with tongs (or a spider strainer for short shapes).
Tip: If your sauce isn’t quite ready, toss the drained pasta with a small knob of butter to help prevent sticking and overcooking.
Finishing the pasta in the sauce
Instead of serving sauce on top of plain pasta, finish cooking the pasta directly in the sauce. This allows the pasta to absorb flavor and gives you a much better final texture and taste.
I undercook dried pasta by about 1 minute, then transfer it straight from the water into the sauce. Let it gently bubble for 2–3 minutes, adding a splash of reserved pasta water as needed. The starch in the pasta water helps loosen the sauce and allows it to cling evenly to the pasta.
What NOT to do
Don’t rinse pasta. Rinsing washes away surface starch that helps sauce cling. The only exception is pasta salad.
Don’t add salt before the water boils. It can damage cookware and makes no difference to the pasta.
Don’t add olive oil to the cooking water. It doesn’t prevent sticking and can stop sauce from coating the pasta properly.
Don’t serve pasta with sauce spooned on top. Always add the drained pasta directly to the sauce so it’s evenly coated.
Finishing touches
Warm the plates or bowls. Pasta cools quickly, so this makes a noticeable difference when cooking for guests. I like to warm bowls in a low oven while the pasta cooks, even 120°F (50°C) is enough.
Have everything ready before you serve. Set the table, pour drinks, and get everyone seated. Pasta is best served immediately, and sauces can thicken or dry out if they sit.
Grate cheese at the table. A microplane and a wedge of parmesan go a long way and makes serving pasta feel a little more special.
Now you'll need some sauces
Once you’ve got your pasta cooking dialled in, the right sauce really shows it off. You’ll find plenty of options in my recipe section, but here are a few reliable sauces to try first.

Ingredients
- 400 grams dried pasta or 600 grams fresh
- 2.5 quarts water that is pretty much 2.5 litres too
- 1.5 tablespoons salt see notes
Instructions
- Please read the notes above, that is where all the useful info is! You'll only need to read it once.
- Boil the water in a medium or large saucepan.
- Add the salt when the water is boiling, not before.
- Add your pasta and cook, undercooking from the package instructions by a minute.
- Reserve a cup of pasta water right before draining.
- Transfer straight into your pasta sauce and let it gently bubble away for a min or two together. Depending on the sauce I usually add about ¼ cup of pasta water at the same time as the pasta.
