The Butter and Onion Trick That Starts Every List of Jarred Pasta Sauce Upgrades

This is the trick that went viral after an Italian grandma shared her one-ingredient spaghetti sauce upgrade, and it is borrowed from the most famous tomato sauce in Italian home cooking. Pour the jar into a pot, add a few tablespoons of real butter and half an onion, cut side down, then simmer gently. The butter rounds off the sharp, tinny edge that many jars have, and the onion adds a quiet sweetness. Fish out the onion before serving, and taste how silky the sauce has become..

You will need: 1 jar (24 oz) marinara or plain tomato sauce, 3 tablespoons unsalted butter, 1/2 yellow onion (peeled), salt to taste, 1 lb spaghetti, grated parmesan.

How to make it: 1. Pour the sauce into a saucepan and add the butter and the onion half, cut side down. 2. Simmer on low, stirring now and then, for 20 to 25 minutes. 3. Remove the onion, taste and season with a pinch of salt. 4. Toss with hot spaghetti and finish with parmesan.

Simmer a Parmesan Rind in the Pot

Italian grandmothers never throw away the hard end of a wedge of parmesan. They keep the rinds in the freezer and drop one into soups, beans and, yes, a pot of jarred sauce. As it simmers, the rind softens and releases a deep, savory, nutty flavor that makes the sauce taste like it cooked all afternoon. The cheese wheels aging in Parma are what give that rind its flavor, and you get it for free. Remove what is left of the rind before serving, or slice the soft bits for the cook. Of all the jarred pasta sauce upgrades nonna swears by, this one wastes nothing.

You will need: 1 jar (24 oz) marinara, 1 parmesan rind (about 2 to 3 inches), 1 tablespoon olive oil, 1 garlic clove (smashed), black pepper.

How to make it: 1. Warm the olive oil with the garlic in a saucepan for 1 minute. 2. Add the sauce and the parmesan rind and bring to a gentle simmer. 3. Cook on low for 20 to 30 minutes, stirring so the rind does not stick. 4. Remove the rind, season with pepper and serve over pasta.

Finish It With a Splash of Starchy Pasta Water

This is the trick restaurant cooks swear by, and nonna was doing it long before them. Scoop out a mug of the cloudy pasta cooking water before you drain the noodles. Then finish the pasta in the pan with the sauce and a splash of that water. The starch turns thick jarred sauce into a glossy coating that clings to every strand instead of sliding off into a puddle at the bottom of the bowl. Among all the jarred pasta sauce upgrades, this one costs nothing at all.

You will need: 1 lb spaghetti or rigatoni, 1 jar (24 oz) marinara, 1 cup reserved pasta cooking water, 2 tablespoons butter or olive oil, grated parmesan.

How to make it: 1. Cook the pasta in well salted water until 1 minute short of al dente. 2. Scoop out 1 cup of the cooking water, then drain the pasta. 3. Warm the sauce in a large skillet, add the pasta and 1/2 cup of the water. 4. Toss over medium heat for 1 to 2 minutes, adding more water until glossy, then finish with butter and cheese.

Roasted Garlic, the Sweetest of All Jarred Pasta Sauce Upgrades

Raw garlic can taste harsh in a quick sauce, but roasted garlic is soft, sweet and almost buttery. Grandmas who keep a little jar of garlic confit in the fridge can turn a plain jar of marinara into something special in seconds. Mash a few roasted cloves into the warm sauce and the flavor melts in completely. It is one of the most loved jarred pasta sauce upgrades because it tastes so rich for so little effort, and the leftover garlic oil is perfect for toasting bread.

You will need: 1 head garlic, 2 tablespoons olive oil, 1 jar (24 oz) marinara, pinch of red pepper flakes, salt, crusty bread for serving.

How to make it: 1. Slice the top off the garlic head, drizzle with oil, wrap in foil and roast at 400F for 40 minutes. 2. Squeeze out the soft cloves and mash them with a fork. 3. Warm the sauce, stir in the mashed garlic and the pepper flakes. 4. Simmer 10 minutes, season and serve.

Melt Anchovies Into Olive Oil First

Do not be scared of this one. When anchovies are cooked gently in olive oil, they dissolve completely and nobody can tell they are there. What they leave behind is a deep, savory flavor that makes tomato sauce taste rich and complex. It is the secret behind spaghetti alla puttanesca, the bold Naples pasta with olives and capers. Add those two to your jar along with the anchovies and you have a famous Italian classic on the table in 15 minutes. It is one of the boldest jarred pasta sauce upgrades on this list.

You will need: 3 to 4 anchovy fillets in oil, 2 tablespoons olive oil, 2 garlic cloves (sliced), 1 jar (24 oz) marinara, 1/3 cup pitted black olives, 1 tablespoon capers, parsley, 1 lb spaghetti.

How to make it: 1. Warm the oil on low, add the anchovies and garlic and stir until the anchovies melt. 2. Pour in the sauce, olives and capers and simmer 10 minutes. 3. Toss with cooked spaghetti and a splash of pasta water. 4. Finish with chopped parsley.

Tear In Fresh Basil at the Very End

Dried herbs in a jar have been cooked for a long time, so they taste dull. A handful of fresh basil, torn by hand right before serving, brings the whole pot back to life with a bright, sweet, peppery smell that fills the kitchen. Grandmas tear basil instead of chopping it because a knife bruises the leaves and turns them dark. Add half to the pot off the heat and scatter the rest over each plate. Keep a pot of basil on the windowsill and this upgrade is always within reach. Simple jarred pasta sauce upgrades like this one are the easiest to remember.

You will need: 1 jar (24 oz) marinara, 1 large handful fresh basil leaves, 1 tablespoon extra virgin olive oil, grated pecorino or parmesan.

How to make it: 1. Heat the sauce until just simmering, then take it off the heat. 2. Tear half the basil into the pot and stir in the olive oil. 3. Toss with pasta. 4. Tear the remaining basil over each plate and add cheese.

Red Wine Reduction for Rich Jarred Pasta Sauce Upgrades

A splash of dry red wine, cooked down before the sauce goes in, gives jarred marinara a deep color and a rounded, almost meaty flavor. The trick is to let the wine bubble until it reduces by half, so the alcohol cooks off and only the flavor stays behind. Use a wine you would happily drink. This upgrade is especially good with beef, sausage or mushrooms, and it makes even a weeknight bowl of pasta feel like a Sunday dinner at a trattoria. It is one of the classic jarred pasta sauce upgrades for a cozy dinner.

You will need: 1 tablespoon olive oil, 1/2 onion (finely chopped), 1/2 cup dry red wine, 1 jar (24 oz) marinara, 1 bay leaf, pinch of dried thyme, salt and pepper.

How to make it: 1. Soften the onion in the oil for 5 minutes. 2. Pour in the wine and let it bubble until reduced by half, about 3 minutes. 3. Add the sauce, bay leaf and thyme and simmer 15 minutes. 4. Remove the bay leaf and season to taste.

Brown Italian Sausage for a Hearty Sauce

Nothing makes a jar of sauce taste more like nonna’s Sunday pot than browned Italian sausage. Squeeze the meat out of the casings, crumble it into a hot pan and let it get properly brown and crispy at the edges before the sauce goes in. That browned layer on the bottom of the pan is pure flavor, so scrape it up as the sauce bubbles. Sweet or hot sausage both work. Serve it over rigatoni and watch the whole family come back for seconds. Hearty jarred pasta sauce upgrades like this one feed a hungry family fast.

You will need: 1 lb Italian sausage (sweet or hot, casings removed), 1 tablespoon olive oil, 1 small onion (chopped), 2 garlic cloves, 1 jar (24 oz) marinara, 1 lb rigatoni, parmesan.

How to make it: 1. Brown the sausage in the oil, breaking it up, for 8 minutes. 2. Add the onion and garlic and cook 4 minutes more. 3. Pour in the sauce, scrape the pan and simmer 15 minutes. 4. Toss with cooked rigatoni and top with parmesan.

Tame Sharp Acidity With Grated Carrot

Some jars taste sharp or sour, especially cheaper ones. Many people reach for sugar, but southern Italian grandmothers often grate in a little carrot instead. As it simmers, the carrot melts into the sauce and adds a natural, gentle sweetness that balances the tomatoes. A pinch of sugar works in a pinch, but the carrot adds body too. It is one of the most budget-friendly jarred pasta sauce upgrades, and picky kids will never notice the extra vegetable.

You will need: 1 jar (24 oz) marinara, 1 small carrot (finely grated), 1 tablespoon olive oil, pinch of sugar (optional), salt, fresh parsley.

How to make it: 1. Cook the grated carrot in the olive oil for 4 minutes until soft. 2. Add the sauce and simmer 15 minutes. 3. Taste and add a small pinch of sugar only if it is still sharp. 4. Season and finish with parsley.

Creamy Vodka-Style Sauce, a Restaurant Favorite Among Jarred Pasta Sauce Upgrades

Penne alla vodka is one of the most ordered pastas in Italian-American restaurants, and you can fake it beautifully with a jar. A splash of vodka sharpens the tomato flavor, and heavy cream turns the sauce a soft blush pink that coats every tube of pasta. The vodka is optional, but it gives that restaurant taste. Finish with parmesan and a pinch of chili flakes, and dinner looks like it came from a fancy kitchen instead of a pantry shelf. Creamy jarred pasta sauce upgrades are always a hit with kids, too.

You will need: 1 tablespoon butter, 1 shallot (minced), 2 tablespoons vodka (optional), 1 jar (24 oz) marinara, 3/4 cup heavy cream, 1/2 cup grated parmesan, pinch of red pepper flakes, 1 lb penne.

How to make it: 1. Melt the butter and soften the shallot for 3 minutes. 2. Add the vodka and simmer 1 minute. 3. Stir in the sauce and cream and simmer 8 minutes. 4. Toss with cooked penne, parmesan and a splash of pasta water.

Swirl in Fresh Ricotta

A spoonful of fresh ricotta stirred into warm tomato sauce makes it creamy, mild and wonderfully comforting, a little like a lazy lasagna in a bowl. Grandmas often leave a dollop of ricotta on top of each plate so everyone can swirl it in themselves. The cool cheese against the hot sauce is the whole joy of it. Season the ricotta with lemon zest, salt and black pepper first, and it turns a plain jar of marinara into something you would happily serve to guests. Few jarred pasta sauce upgrades are this gentle and comforting.

You will need: 1 jar (24 oz) marinara, 1 cup whole milk ricotta, zest of 1/2 lemon, salt and black pepper, 1 lb short pasta, fresh basil.

How to make it: 1. Mix the ricotta with the lemon zest, salt and pepper. 2. Heat the sauce and toss it with the cooked pasta. 3. Stir half the ricotta through the pasta. 4. Top each plate with a spoonful of the rest and torn basil.

Add a Calabrian Chili Kick

If you like a little heat, take a cue from Calabria, the toe of Italy’s boot, where crushed chili peppers go into almost everything. A spoonful of crushed Calabrian chilies in oil, or a good pinch of red pepper flakes, turns a mild jar into a fiery arrabbiata, which means angry in Italian. Bloom the chili and garlic in olive oil first so the heat spreads evenly. It is perfect with penne and a shower of pecorino. Spicy jarred pasta sauce upgrades like this one wake up any weeknight.

You will need: 2 tablespoons olive oil, 3 garlic cloves (sliced), 1 to 2 teaspoons crushed Calabrian chilies or 1/2 teaspoon red pepper flakes, 1 jar (24 oz) marinara, 1 lb penne, parsley, pecorino.

How to make it: 1. Warm the oil with the garlic and chili on low for 2 minutes. 2. Add the sauce and simmer 10 minutes. 3. Toss with cooked penne and a splash of pasta water. 4. Finish with parsley and pecorino.

Slow Cooker Meat Sauce Tops Our Sunday Jarred Pasta Sauce Upgrades

This is the Sunday ragu shortcut that busy grandmas do not always admit to. Brown ground beef and pork with onion, carrot and celery, then let it simmer all day in the slow cooker with two jars of sauce and a splash of milk. By dinner the meat is meltingly tender and the sauce tastes like it took hours of stirring, because it did, just not by you. Serve it over wide ribbons of tagliatelle or pappardelle for a real northern Italian feeling. Slow jarred pasta sauce upgrades like this one fill the house with a wonderful smell.

You will need: 1 lb ground beef, 1/2 lb ground pork, 1 onion, 1 carrot, 1 celery stalk (all finely chopped), 2 jars (24 oz each) marinara, 1/2 cup milk, 1 bay leaf, salt and pepper, tagliatelle.
