You know how sun-ripened tomatoes straight from the garden taste 1000% better than anything you can buy in the store? Pasta sauce from fresh tomatoes is the same way – you’ll never go back to grocery store jars. This recipe for Easy Homemade Roasted Tomato Sauce makes a delicious pasta sauce. It’s perfect for serving over noodles, turning into soup, or using in any recipe that calls for canned tomato sauce. You’ll love how easy it is to make your own roasted tomato sauce!

I first shared this post in 2012 and it’s been a popular post. I make this recipe a lot during the gardening season, so it’s high time I updated it with more specific cooking instructions and pictures.
Easy Homemade Roasted Tomato Sauce
I love to can tomatoes and also keep them in my freezer. Once you make this sauce, you’ll never go back to the jarred grocery store options. Eat it fresh, preserve it in your freezer or can the sauce and you’ll have that fresh-from-the garden flavor all year long.

Ingredients to Make Your Own Tomato Sauce
One thing I love about this recipe is it uses produce I generally have growing in my garden and items I always have in my pantry. Here’s all you need to make this easy homemade roasted tomato sauce:
- Fresh basil
- Paste tomatoes
- Garlic
- High smoke oil (I prefer avocado)
- Balsamic vinegar
- Salt and Pepper
Best Tomatoes for Homemade Sauce
You can use whatever tomatoes you want, but a good quality paste tomato works best. Paste tomatoes aren’t as watery and will make a thicker, more flavorful sauce. Choose ripe tomatoes for the best flavor. I grew San Marzano tomatoes this year from seeds I purchased at Baker Creek. This is the first year I have grown them, and I am very impressed! I will grow them again next year for sure. I also throw in any cherry or grape tomatoes I have on hand. Roma tomatoes are another popular variety for homemade sauces.
How to Make Homemade Pasta Sauce from Roasted Tomatoes
The first step is to prepare your tomatoes. Wash the tomatoes well. Cut off any bad spots and take out the stem (I just cut off the top of the tomato). Then, halve or quarter the tomatoes.

I do not peel the tomatoes before processing. Scandalous, I know. I never peel the tomatoes I can – it takes too much time, and I am a lazy canner. I have to find ways to reduce my time commitment.
Next put everything on a high rimmed baking sheet or in a 9×13 in pan. I recommend the 9×13 because they become quite juicy and can overflow into your oven and make a big mess. {ask me how I know this…} Add garlic and fresh basil, top with good quality olive oil, sea salt and pepper. Then roast at 425 degrees for an hour.
After an hour, pull them out of the oven and they will look pretty ugly, but your kitchen will smell heavenly! I promise.

Let the tomatoes cool for 15-20 minutes and then put them in a blender. I love making pasta sauce in my Vitamix as well as soups and smoothies.
Blend on the lowest speed for a few seconds and then quickly increase to the highest speed until desired consistency is reached. I like mine very smooth and creamy. It takes about 30 seconds or so – and VOILA! Roasted Tomato Sauce!
How to Freeze Homemade Pasta Sauce
This sauce results in a rich, creamy pasta sauce. It’s awesome as a quick, meatless lunch, or great to use as a base for recipes. It also makes a fabulous roasted tomato soup! After we’ve eaten a serving, I put the leftovers in glass canning jars and freeze for another day.
Before freezing tomato sauce, make sure it is completely cool. Leave an inch of headroom so there is space for the sauce to expand as it freezes. Store the sauce in your freezer up to three months. Be sure to label each container so you know which should be used first.
Glass canning jars, freezer-safe Pyrex containers, or even freezer bags work well. If you use glass jars, be sure the glass is thick enough to freeze and thaw without breaking. Always place the containers into the freezer upright.

How to Can Roasted Tomato Sauce
Disclaimer: Water bath canning is NOT recommended as a safe way to preserve this recipe. The recipe has not been tested for acidity level, and it not officially approved for water bath canning. If you want to preserve this long term, I recommend freezing the sauce instead of water bath canning.
Make all of your sauce as directed above and put it in a great big stock pot. Simmer it to keep the sauce warm.
Heat up the water in your water bath canner. Once it’s boiling, sterilize your clean jars by boiling them for 10 minutes.
Prepare your canning lids by submersing them in steaming, but not boiling, water for a few minutes. I use both BPA free Tattler Reusable Canning Lids and the normal Ball Canning Lids
which are now also supposed to be BPA Free!! YAY!!
Use a ladle to fill your jars with the sauce. To minimize mess, you can also use a funnel into the jar. Leave at least 1/4 inch headroom at the top of the jar AFTER you add 2 TBS lemon juice concentrate (VERY IMPORTANT STEP!!) per jar. Wipe the rim of the jar and lid. Do not leave any sauce or food residue as it will prevent your jars from sealing.

As you finish each jar, place it in the water bath canner to keep it hot. It is recommended that you completely finish one jar at a time for optimal results – not the batch method I display here… Do as I say, not as I do. 🙂
Put your lids on and tighten securely. Once your canner is full, boil the jars for 45 minutes. Add 5 minutes per 1,000 feet to compensate for the altitude. I live at just under 1,000 feet. If you live at 2,000 feet, process for 50 minutes. If you live at 3,000 feet, process for 55 minutes, and so on. If you don’t know your altitude, just google it.
Carefully remove the jars and put them on a clean towel. Let them cool for a full 24 hours before you move them. Sit back and listen to the wonderful pings of the sealing jars! After 24 hours, make sure all of your jars have sealed. Wipe them down, remove the rings, and put them on a shelf to admire. If any jars didn’t seal, you can heat the sauce back up and try again or just use that sauce immediately.
What Can You Make with Homemade Roasted Tomato Sauce?

Hello! I’ve an abundance of fresh tomatoes and I found your recipe to can a bunch of basic sauce to use them up. However the very day I was going to make your sauce, I decided to make beef red enchiladas for dinner. Oh no! I had only one small can of tomato sauce! I remembered your recipe and decided to tweak it a little. Instead of using basil I used some fresh cilantro, I left out the balsamic vinegar, and after I had blended everything I added the enchilada seasoning. We finished it off that night, so I didn’t can any. Thank you so much for saving my dinner!

Just finished making this and it is delicious! I wish I had read the comments before dumping the juices from the pan. I could have thinned the sauce with it. Honestly, I didn’t measure my tomatoes. I just dumped what I had into the pan along with the rest of the ingredients and it came out so good. Also removed some of the skins from the tomatoes as they pulled right off. Gonna freeze mine in leftover wonton soup containers. Thanks

Wow! Followed the directions…425 is definitely too hot and at an hour too an hour and a half? Lots of charred tomatoes. Super bummed because they come from our garden and I was so excited. Please beware and watch while roasting.

Sorry you had trouble. I make this recipe all the time with no issues. Other than cooking for less time or at a lower temp, you might also leave your tomatoes in larger pieces.

Would a good processor work instead of a blender? I no longer own a blender, but I do have a food processor.

I have not used a food processor - but you can try it! I'd just be careful not to overfill the processor container - mine at least has a hole that could let out the liquid and that would make a huge mess.
