Simple Marinara Sauce for Canning

This is my third year of canning tomatoes.  Nick loves gardening and the first year that we had the garden, I was so excited to make my own tomato sauce.  I looked up a ton of recipes and ended up with a recipe that had a ton of ingredients (tomatoes, onions, carrots, celery, garlic, balsamic vinegar, red wine, etc.)  It was a lot of fun to do, but I had some ideas for improvement.  The sauce turned out pretty watery and I spent a LOT of time doing prep work.  I also didn’t feel like the added elements enhanced the sauce, I realized I prefer a simpler, more tomato-y tomato sauce.  The next year, we didn’t have a garden as we had just moved into our house in Wilmington but I bought about 20 lbs of tomatoes from a local CSA and canned whole tomatoes.  It was so much easier!  And the tomatoes made a great base to crush up and add some garlic/onions/basil to, to make an easy sauce for pasta.

This year I decided to meet in the middle of those two attempts.  I wanted a sauce that was simple and less time consuming, but also ready to use right out of the jar.

We planted about 6 San Marzano tomato plants this past year in the garden.  As the tomatoes ripened, I would just throw them into a bag in the freezer to can later.  We ended up with roughly 30 lbs of tomatoes

Overall this process has three phases:

  • Prep the tomatoes
  • Make the sauce
  • Can the sauce

You will need the following materials:

  • Lots of large bowls
  • Food scale (I suppose you could do without this and just play with the ratios of other ingredients)
  • At least two large pots
  • Immersion blender (you could use a regular blender but it will be a lot messier I think)
  • A boiling water canner and associated tools (we bought a kit from Walmart I think?  It came with tongs and stuff to pull the cans out)
  • Jars, bands and lids
  • Tomatoes
  • Olive Oil
  • Butter
  • Garlic
  • Basil
  • Tomato paste

If you are doing it all in one day like I did, the whole process takes about 4 hours (with a fair amount of inactive time in there where you could do other things).  So, get your space set up, get in some comfy clothes, put on some good music (maybe grab some wine 😉 ) and get to working.

Prep the tomatoes

If you are planning on canning the same day as making the sauce, you should decide now how you are going to sanitize all of your canning materials (I know.  The first step in prepping our tomatoes, and we aren’t even talking about freaking tomatoes).  My dishwasher has a high temperature, sanitize setting so I used that.  It takes about three hours to run, so I started that now so it could run while I was working.  You want the jars to be warm/hot when you fill them, so that the glass doesn’t crack or break.  Since the cycle would be ending right as I would be ready to can, they would still be warm from the cycle.  Another option to sanitize is to put the jars in simmering water.  If you take this approach, you can wait until you are closer to can to worry about your jars.  See this Ball post for more directions.

Now, on to the actual tomatoes!  We need to get these bad boys peeled.  To do this, we are going to get two pots of boiling water going and get all of our frozen tomatoes weighed out and in bowls, ready to go.  We are going to submerge the tomatoes in the boiling water for 30 seconds – 1 minute (however long it takes for the skin to start peeling away).

While waiting for the water to come to a boil, I did some other prep work and chopped up my onion.  I used 1.5 giant softball sized onions to yield 4 cups of chopped onion.

Once the water is boiling throw some tomatoes in.  You can see in the pic below how the skins start to peel back.  Once that happens, you can take the tomato out (I used a pasta scoop to rescue the peeling tomatoes) and finish peeling off the skin.  It should come off pretty easily, for most I just rubbed and they came off in one piece.  I also performed some quality control at this point and had a paring knife close by to cut out bad spots.  

I used a three bowl process.  Bowl 1 in the far back is holding the frozen tomatoes ready to go in.  Bowl 2 on the front left is where the tomatoes go after coming out of the water and to be peeled.  Bowl 3 on the right holds the naked, “prepped” tomatoes.

At first, I tried to do this with a constant, assembly line approach with a few tomatoes at a time for efficiency.  I was able to peel while the next batch of tomatoes were in the water.  But I found that this reduced the temperature of the water too much, since it was never able to come back up to boiling, and the skins weren’t bursting.  So I went to batches.  I would throw tomatoes in, let them start peeling, fish them back out, and then peel while the water was empty and coming back up to temperature.  Do this process over and over (and over…and over……) until all of your tomatoes are prepped.

Making the Sauce

Once all of your tomatoes are prepped, you are ready to start making your sauce!  I continued with two pots, if you had less tomatoes (15 lbs or so) you could work with just one.

I got some olive oil and butter going (about a tablespoon of each) and threw half of the onions in each pot.

While I had it melting, I remembered that I preserved some basil in olive oil (using muffin pans and freezing it) over the summer, so I threw some of that flavored olive oil in too.

DSC_0740After your onions are translucent (about 5 minutes), add all of your tomatoes and juice.


I let these go for about 20 minutes, to ensure the tomatoes weren’t frozen any longer and had broken down some.  Then I busted out my handy dandy immersion blender.  You could also use a regular blender and blend it in batches, but this could be messy and you would have to be careful with the hot sauce.  If you are working with a smaller batch, this might be an ok approach though.  DSC_0746

You can see how watery the blended sauce is at this point.  Next, we want to reduce and thicken the sauce.  I also added three small cans (8 oz each) of tomato paste at this point to help move it along.  I like doing this because you save time spent reducing and end up with more final product, but you could leave it out and just let it cook off and reduce until you reach your intended thickness.


I also chopped up my basil (I used one plastic clamshell, but in retrospect I wish I would have used two) and added it at this point.  DSC_0758DSC_0759

I let it cook about an hour, you can see below how the sauce has thickened.  This part is really personal preference, if you prefer a thicker sauce you can let it go even longer.DSC_0762

Canning the Sauce

Now for the fun part (sort of).  Gather all of your canning materials and fill up your boiling water canner and start heating.  Using a funnel (you want to keep the jars as clean as possible), start scooping in sauce, leaving about 1 inch of headspace.


After your jars are filled, add about 1 tablespoon of lemon juice to each jar (to raise the acidity of the mixture, an important aspect of water bath canning).  Then add your lids and bands.  Hopefully by this part your water is boiling and you are ready to process them.

Ready to take a dip


Tomatoes and tomato sauce take approximately 35 minutes to boil, so put them in, slap on the lid and go relax for 35 minutes.  Or ya know, be efficient and do some laundry or something.

I actually ran out of lids (why didn’t I check that before starting?  I don’t know), so I decided to freeze our remaining sauce in ziploc bags.  To do this, I waited until the sauce was pretty cool and added about 4 cups of sauce to each gallon size freezer bag.  That random can on the right is sauce that I set aside for us to have this week, so it didn’t need a dip in the water bath.

Our full bounty

After your jars are finished processing, move to a dark cool place and allow them to sit for 24 hours.  You will probably hear some popping as the cans seal.  You want to end up with lids that don’t have any give and you aren’t able to push down.  That’s the sign of a good seal!  I was happy that all of ours sealed.  If you end up with some that don’t, you can refrigerate and eat that week, or freeze instead.DSC_0771

Shh…go to sleep little jars
The unfortunate aftermath

Overall we ended up with 5 quart jars, 5 pint jars, 3 gallon sized bags, and one quart sized bag.  44 cups of sauce!  All of our Nick’s blood/sweat/tears from gardening this summer was totally worth it.

Here is some of the sauce we had this week on some campanelle pasta with a chicken sausage.  Delicious!

What is your favorite kind of tomato based sauce?  Have you ever canned before?

WIAW: Sorry all my food is gross looking

Unfamiliar with What I Ate Wednesday (WIAW)? WIAW is a blogger link-up created by Jenn over at Peas and Crayons.  The idea is that once a week, you keep track of all of your eats for a day and share.  The very first blogs I started reading were daily food journal type blogs, so even though that’s not a popular format anymore, it was cool to be able to write my own post in that style.

I will say that nothing makes you overly scrutinize your food like knowing that you will be posting it for the world to see.  After I uploaded all of the photos, I’m like “UGH I ate two tortillas in one day, not enough variety!  All of my food is too mushy and ugly!  What if they think I eat too much dairy?!?!?!”  But I think that’s the beauty of WIAW.  No one eats beautiful food all the time!  And it’s cool to get real, practical ideas from all different kinds of lifestyles and diets.

And also in my defense, we bought a pack of tortillas from Costco this past weekend and I am DETERMINED not to waste food so I will be rolling anything and everything into a tortilla until those bastards are gone.

I woke up with some extra time this morning (a rare occurence) so I took some time to make my favorite breakfast, eggs!  I scrambled these on low in butter and then added a slice of cheese on top.

Breakfast: Tortilla with two scrambled eggs, covered in a slice of cheese and smashed avocado. And hot sauce (of course). Normally I wouldn’t do cheese AND avocado, but I was still waking up apparently and started melting the cheese without thinking. So, two delicious things on my eggs it is. Oh noooo.

A latte, made with one “Lungo” sized Nespresso and a cup of steamed milk. I also added Salted Caramel Syrup. Sorry for that unappetizing drip on the side.  
Work today was pretty uneventful.  Spreadsheets, meetings, etc.

Mid-morning green tea at work. I felt like a complete jackass styling this little photo with the tea box and prayed no one walked by my cubicle while I was doing this.

Morning snack: I got all the way through peeling this before I remembered to take a pic of this tangerine. WIAW is hard.

Lunch: My salad that I eat almost every day. Spinach, romaine, chicken, bleu cheese, tomatoes, cucumber, and dried cranberries. With homemade balsamic (Balsamic, evoo, salt, pepper and dijon).

More tea, because my office was cold af today.
I actually had a meeting today at 3:00 which is the exact time that I like to partake in my afternoon snack, how dare they.  So I had a later than normal snack.

I’ve been making my own hummus lately and really like being able to customize it.

Afternoon snack: Roasted red pepper hummus and baby carrots.

More afternoon snack: Two babybels. Got halfway through peeling the first one before I remembered to take a picture, an improvement from my morning snack.
After work, we headed to the gym where I ran on the treadmill.  I did a tempo run (10 min comfortable pace, 15 mins at a medium difficulty pace, 10 min cooldown at comfortable pace) where I cranked that bad boy all the way up to 6.2 mph for the tempo part.  Wow, it was tough.  I was sweating like a mofo and my face was BEET red.  Trying to get faster is hard work.

Dinner: Another tortilla! With crockpot salsa chicken, black beans, corn, and fajita veggies. Topped with more smashed avocado. I also added some more salsa after this pic was taken.

 I really enjoyed participating in WIAW this week!  Hopefully my pictures weren’t too insanely boring or nausea-inducing.

And in conclusion, I think I have a tea problem and will be seeking help soon.  Thank you for your support during this difficult time.

How much tea do you drink on a daily basis? Make me feel better about my consumption please? 

Random Friday #4

Wow, 4 whole Friday’s of blogging?  Time flies when you are having fun reliving your vacations I guess!

Me, today.
Me, today.
  • I have grave news.  I attempted to download iOS 9.2 and it crashed my phone.  I am currently phoneless while my poor little broken phone is at home trying to restore itself.  All because I wanted the new taco emoji.  I will never look at tacos the same again (that’s a lie, I love tacos).
  • This weekend will be a really fun one, I am headed to Richmond for healthnut’s bachelorette party!  We are going to have a spa day followed by a night out, I can’t wait!
  • Recovery from the half marathon has went really well.  I felt less sore than I have with previous halfs (halves?? Someone please tell me!!).  The only thing I really did differently (except for not completing my training) was the compression socks.  I will be wearing these always.
  • Also unlike previous races, I actually feel like I want to continue running and work on my speed for a while.  I still want to continue on with the Lauren Gleisberg plan I mentioned previously, but will shoot to incorporate two run days per week.  I’m eyeing a Turkey Trot 5k or a Jingle Bell Run for some short-term motivation.
  • I started reading “The Goldfinch” by Donna Tartt this week.  I’m only 50 or so pages in and I’m having some trouble really getting into it.  Has anyone else read this one?  I wanted to continue the Joe Abercrombie series I mentioned last week, but they don’t have books 2 or 3 available at my library.
  • Dinners were really good this week!  Nick had a ton of poblanos from our garden that needed to be used up so we made up a stuffed pepper recipe of sorts.  I cooked some ground beef with onions, garlic, chili powder and cumin.  We mixed that with black beans, mexican blend shredded cheese and green enchilada sauce.  We stuffed the peppers with the mixture and put them in a 9X13 pan.  I then put more cheese and enchilada sauce over the top.  It turned out great!  We served it with rice, salsa, and extra cilantro.

Talk to me: What are your plans this weekend?  Have you read any good books lately?
