Homemade Tomato Sauce for Canning. 6 Simple Proven Steps

The turkey fryer is finally getting its moment.

We have been talking about it since the beginning of this summer on Farmstead Chronicles — the gift from my husband that has been sitting in the shed waiting patiently for the right day. The day the tomatoes came in. The day the Roma tomatoes from our local farmers were ready and the market tables were set up outside and Lil Bit showed up ready to help.

That day is here.

Lil Bit baked us chocolate chip muffins this morning. That is just who she is — the kind of person who shows up with something homemade and then rolls up her sleeves and gets to work beside you all day. She loves to learn. She loves to help. And she is going to be right there with us on the homemade tomato sauce for canning day, which means this is not just a canning tutorial. It is a memory being made.

My husband — who is Italian and has very specific opinions about tomato sauce that I have learned to take seriously — will be the deciding vote on what goes in it. Garlic certainly. Basil probably. Whatever his Italian heart tells him belongs in a proper sauce. This is his domain and I am happy to let him have it.

We are also canning diced tomatoes on the same day because Roma tomatoes at their peak deserve to be used completely and nothing from this harvest is going to go to waste.

Two first-time canning projects. One turkey fryer. A beautiful summer day outside. And Lil Bit beside us for all of it.

Let us get into it. 🍅

“She looketh well to the ways of her household, and eateth not the bread of idleness.”
Proverbs 31:27 KJV

She looks well to the ways of her household. She shows up. She does the work. And sometimes the work happens outside on market tables with a turkey fryer and a woman who baked muffins before she ever got here.

That is a good day. 🙏

1. The Turkey Fryer Gets Its Moment

Back in the very first post of our Harvest and Preservation series we talked about the turkey fryer sitting in the shed. The gift from my husband last summer. The one that has been waiting patiently for the right project.

This is it.

We are setting up outside on the same tables we use for the market. The turkey fryer goes on. The large pot goes on top of it. And the homemade tomato sauce for canning adventure begins in the fresh air with the summer all around us instead of in a hot kitchen that would turn our tiny house into a sauna.

This is exactly why he bought it. And it is exactly right. 🌿

2. Why Roma Tomatoes and Why Outside

Roma tomatoes are the gold standard for homemade tomato sauce for canning and here is why.

They are a paste tomato — meatier, less watery, with thicker walls and fewer seeds than slicing tomatoes. That means your finished sauce is thicker and richer without having to cook it down for hours. They are the tomato your grandmother would have chosen and the tomato your Italian husband will approve of.

We source ours from local farmers — the same ones we trust to supply our own customers. Peak season Roma tomatoes from a real farm make a completely different sauce than anything you will find at a grocery store.

And outside is the right answer for homemade tomato sauce for canning in a small home for exactly the reason we already talked about. A large pot of tomato sauce simmering for hours in a small kitchen on a hot summer day is a commitment your air conditioner may not survive. The turkey fryer outside solves all of that beautifully.

3. What You Need Before You Begin

Equipment:

• Turkey fryer burner and large outdoor pot OR a large heavy bottomed pot on your stove
• Large stockpot if using the stovetop method
• A food mill OR an immersion blender for smoothing the homemade tomato sauce for canning
• Wide mouth quart Mason jars
• Canning funnel
• Jar lifter
• Water bath canner or large pot with rack

Ingredients for Basic Tomato Sauce:

• 20 pounds Roma tomatoes — roughly 7 quarts finished sauce
• Olive oil
• Garlic — as much as your Italian husband thinks is appropriate 😄
• Fresh basil
• Salt to taste
• 2 tablespoons bottled lemon juice per quart jar — safety requirement, do not skip

Important safety note: The lemon juice is not optional. Tomatoes vary in acidity and the added lemon juice ensures the pH is safe for water bath canning. This is the rule we follow every single time without exception.

4. Six Simple Steps to Make Homemade Tomato Sauce for Canning

Step 1 — Wash and Prepare the Tomatoes

Wash your Roma tomatoes thoroughly. Core them and remove any bad spots. You do not need to peel them if you are using a food mill — the mill will handle the skins. If you are using an immersion blender blanch them briefly in boiling water until the skins split then slip the skins off before proceeding.

Step 2 — Cook Down the Tomatoes

Place your prepared tomatoes in your large pot with a little olive oil and cook over medium heat stirring occasionally until they are completely broken down and soft. This usually takes 30 to 45 minutes.

If you are using the turkey fryer outside adjust your flame to maintain a steady medium heat. Not a rolling boil — a gentle steady simmer is what you want.

This is the part where the kitchen — or in our case the great outdoors — starts smelling absolutely incredible. Deep red. Rich. Like summer concentrated into something your family is going to open in February and feel grateful for. 🍅

Step 3 — Mill or Blend Until Smooth

Run your cooked tomatoes through the food mill or use your immersion blender to smooth the homemade tomato sauce for canning to your preferred consistency.

We are going for smooth homemade tomato sauce for canning — the kind my husband approves of and Lil Bit can help pour through the food mill while Grammy turns the handle.

Step 4 — Season the homemade tomato sauce for canning

Return the smooth sauce to the pot and add your seasonings. Garlic. Fresh basil. Salt. Whatever your Italian husband has decided belongs in a proper sauce.

Cook for another 20 to 30 minutes to let the flavors develop and the homemade tomato sauce for canning thicken slightly. Taste and adjust as needed.

Momma Missy’s Garlic Herb Farmhouse Seasoning Mix is what we reach for when we want the garlic herb flavor of a proper Italian sauce in everything we make from the pantry shelf all winter long. 🌿

Step 5 — Fill the Jars

Add 2 tablespoons of bottled lemon juice to each quart jar before filling. Use your canning funnel to ladle the hot sauce into hot jars leaving half an inch of headspace. Wipe rims clean. Apply lids and bands fingertip tight.

Step 6 — Process in the Water Bath Canner

Process quart jars for 40 minutes in a boiling water bath. Pint jars for 35 minutes. Remove and let cool undisturbed for 24 hours. Listen for the pings. Check seals. Label with the date.

A shelf of home-canned homemade tomato sauce for canning made from local Roma tomatoes is one of the most satisfying sights in a farmstead pantry. And opening one in January to make a pasta sauce that tastes like summer — that is the whole point of every jar we filled. 🍅

For all safe processing times and guidelines the National Center for Home Food Preservation is where we go first and last.

5. How to Can Your Diced Tomatoes Too

Since the Roma tomatoes are already out and the turkey fryer is already going and Lil Bit is already there helping — we are also putting up diced tomatoes on the same day.

Because waste is not part of the homemade tomato sauce for canning farmstead philosophy.

For diced tomatoes:

Blanch whole Roma tomatoes in boiling water for 30 to 60 seconds until the skins split. Transfer to an ice bath. Slip the skins off. Core and dice roughly.

Add 2 tablespoons bottled lemon juice to each quart jar. Pack diced tomatoes into hot jars pressing gently to fill gaps, leaving half an inch of headspace. Add 1 teaspoon salt per quart if desired. Wipe rims. Apply lids and bands.

Process quart jars 45 minutes in a boiling water bath. Pint jars 35 minutes.

That is it. Two products from the same harvest. One beautiful canning day outside in the summer air. 🍅

6. Tips From the Farmstead Kitchen

A few things worth knowing before you make homemade tomato sauce for canning this season:

Use bottled lemon juice not fresh. Bottled lemon juice has a standardized acidity that fresh lemons do not. For safe water bath canning of tomatoes always use bottled.

Do not reduce the processing time. 40 minutes for quart jars of tomato sauce is not a suggestion. It is the tested safe minimum. Set a timer and let it run.

The turkey fryer outside is a game changer. If you have a small home and a large canning project seriously consider moving it outside. Fresh air, no steamy kitchen, and the satisfaction of doing something that feels genuinely farmstead. Highly recommend. 🌿

Let Lil Bit help. Or whoever your Lil Bit is — the person who shows up ready to learn and ready to work and makes the whole day better just by being there. Some of the best farmstead memories are made on the canning days. Let the people you love be part of them.

Track everything. How many pounds of tomatoes. How many jars. What you seasoned it with. What you want to change next year. The Sourdough Baking Journal — Blue Bread Notes from our Quiet Nook holds all of it and is one of the most useful things in our farmstead kitchen. 🌾

7. Your Table Challenge This Week

This week your Table Challenge is to invite someone into your kitchen.

Not to entertain them. Not to impress them. To work alongside them. To let them help with something real — the canning, the homemade tomato sauce for canning making, the diced tomatoes, whatever is happening in your farmstead kitchen this week.

Let someone who loves to learn stand beside someone who is learning right along with them.

That is how Gram taught. That is how Mr. Bill at Anderson’s taught. That is how homemade tomato sauce for canning knowledge gets passed from one pair of hands to the next.

“Iron sharpeneth iron; so a man sharpeneth the countenance of his friend.”
Proverbs 27:17 KJV

Invite someone in. Work alongside them. Let the canning day be the teaching. 🙏
