Homemade spaghetti sauce is so easy to make from scratch, and it’s budget-friendly too! It’s the perfect healthy family dinner, and it’s great for meal prepping too.

I’ve used my giant stockpot to make batches with 10 pounds of meat before. (I was able to cool it down quickly outside in the winter.) Then I portioned it out and froze it for the quickest-ever meals.

Whether you have your sauce already made or not, you’re in for a tasty dinner in under 30 minutes with very little hands-on time. If you do meal prep and freeze the sauce, you can have dinner on the table in 15 minutes when the pasta is done!

And since everyone I know grew up with a slightly different spaghetti sauce, I hope you’ll customize this to your taste. My mom never put red peppers in her spaghetti, but many do, and some enjoy green bell peppers too.

If you have fresh herbs around during the summer months, it’s nice to simmer a sprig or two of basil in your spaghetti sauce. This sauce is very customizable and I hope you’ll enjoy it.

Ingredients & Substitutions

Italian sausage, onion, garlic, canned tomatoes, Italian seasoning, and parmesan rind in bowls on a wood cutting board.
  • Italian sausage – I use mild, but you can use hot Italian sausage as well to change things up. You can also use ground beef here, but you may want to add a little extra Italian seasoning in that case. Using Italian sausage rather than ground beef adds so much flavor that everyone will want to know your secret. Spaghetti sauce can even be made with ground pork or ground turkey, but you’ll want to add a bit more spices.
  • Onion & garlic – are the foundations of flavor in spaghetti sauce. You can save some prep time by adding the onion in large chunks to a food processor and processing it into small bits with the garlic.
  • Italian seasoning – add just the right amount of flavor to spaghetti sauce without being overwhelming. I find it gives you enough oregano flavor without needing to add any extra. However, everyone grew up with a different spaghetti sauce, so be sure to adjust this recipe to suit your tastes.
  • Canned tomatoes – whole or diced canned tomatoes tend to have a better flavor for spaghetti sauce rather than starting with tomato sauce. You can squish them with your hands as you add them to the pot, or give them a quick blend in a blender. I love using fire-roasted tomatoes for even more depth of flavor.
  • Parmesan rind – I learned this trick from an authentic Minestrone recipe. Adding a parmesan rind while your spaghetti sauce simmers is the easiest flavor booster. But you definitely don’t need to add it if you’re dairy-free.

How to make this recipe step by step

Dicing up an onion on a wood cutting board.

Step 1: Start by dicing up the onion. Or to save some time, quarter the onion and add it to a food processor along with the garlic and process until it’s small pieces like the above picture.

Step 2: Next sauté the Italian sausage using a wooden spoon or utensil to break it up into small pieces.

Adding the onion, garlic, and Italian seasoning to the cooked Italian sausage.

Step 3: When the sausage is partially done, add the onion, garlic, and Italian seasoning. Continue to cook, stirring occasionally until the onion just begins to turn color, 2-3 minutes.

Add a little olive oil if there isn’t enough oil from the sausage to cook the onions.

Adding the blended canned tomatoes to the sausage mixture along with the parmesan rind.

Step 4: While the onion cooks, blend the canned tomatoes into a mostly smooth sauce. Then add it to the cooked onion sausage mixture along with the optional parmesan rind. Push the rind into the sauce to submerge it and bring the sauce to a simmer.

Simmering Homemade Spaghetti Sauce in a large white pot on the stove top.

Step 5: Keep the heat very low and simmer the spaghetti sauce until it’s lightly thickened and the flavors meld about 20 minutes. Stir only occasionally to make sure it’s not sticking.

The best way to keep spaghetti sauce from splattering is to refrain from stirring as much as possible. The thinner liquid will build up on the top which is what prevents the big splatters.

Ways to serve this

  • Serve this Homemade Spaghetti Sauce the classic way with cooked spaghetti and freshly grated parmesan. Chopped fresh parsley or basil adds nice color and flavor whenever you have them, but it’s not necessary.
  • For a grain-free or paleo option, try this spaghetti sauce over spiralized butternut or sweet potato noodles. Both of those veggies are a touch sweet which goes really well with spaghetti sauce. If you don’t have a vegetable spiralizer, try cubing them up and roast at 450ºF until tender, 20-30 minutes.
  • Add a veggie side dish with my Garlic Roasted Carrots, Roasted Broccoli, Garlic Green Beans, Perfect Asparagus, or Roasted Brussels Sprouts.
  • Or a side salad with my Easy Green Salad, Caesar Salad w/o the chicken, or my Apple Spinach Salad.


Is it worth it to make your own spaghetti sauce?

Yes, this is one of those things that really is significantly better made from scratch. Luckily it’s easy to make your own spaghetti sauce and it’s budget-friendly too. Homemade spaghetti sauce tastes more balanced and less sour than any store-bought brand I’ve tried.

Should pasta be drained and rinsed?

No, just drain the pasta but don’t rinse it. This leaves a bit of starch on the pasta which helps it adhere to the pasta sauce. However, there’s always an exception! If for some reason your pasta has to sit draining for a little bit before you add it to the sauce, you can rinse it with just enough water to help it unstick. Obviously, this isn’t ideal, but kitchen timing doesn’t always go right!

Why should you put sugar in spaghetti sauce?

A touch of sugar will help to balance the acidity of the tomatoes. This is unnecessary if you have good-quality canned tomatoes. The cheapest store-brand canned tomatoes do tend towards the sour side in sauce, so add sugar to taste. You can also use a touch of honey or maple syrup to adjust the spaghetti sauce to your taste.

Storing leftovers

  • To store – keep leftover spaghetti sauce in an airtight container in the fridge for up to 5 days.
  • Make ahead – spaghetti sauce is perfect to make ahead because the flavors get even better. You can make it 2-3 days ahead and still keep your leftovers for up to 2 days in the refrigerator.
  • Reheating – heat over medium heat stirring often in a saucepan until heated through. If you toss the spaghetti sauce together with pasta, reheat the same way as previously directed, but add water as necessary to keep the pasta from sticking.
  • To freeze – spaghetti sauce freezes beautifully, place it in an airtight freezer-safe container and store it in the freezer for up to 3 months.

Tips & Tricks

  • Try all 4 of my flavor tricks! 1) use Italian sausage rather than ground beef 2) try the parmesan rind trick if you’re not dairy-free 3) use fire-roasted tomatoes for more depth of flavor 4) don’t go too heavy on the dried herbs. We love spaghetti with just enough flavor from the herbs to pique your interest, but they’re in balance to let the other flavors shine through too.
  • For gluten-free pasta, try Jovial 100% brown rice spaghetti, it has an amazing texture. You can also toss spaghetti sauce together with any shape of pasta you like, penne and farfalle (aka bowties) are favorites in our house.
  • Simmer the pasta together with the sauce for 1-2 minutes so the sauce perfectly coats the pasta, and starts to impart its flavor.
  • Always use freshly grated parmesan – not from a can or tub of pre-grated cheese, there is a massive difference in flavor.

Dietary Options & Substitutions

  • Dairy-free – be sure to omit the parmesan cheese and use your favorite dairy-free option instead.
  • Paleo – omit the parmesan and serve this spaghetti sauce over spiralized butternut or sweet potato noodles. Or roast your favorite root veggies and spoon spaghetti sauce over them. My Baked Sweet Potatoes or Roasted Sweet Potatoes are perfect for this. You can see a photo of what spaghetti sauce over butternut noodles looks like with my Chorizo Spaghetti over Butternut Noodles.
