Homemade Tomato Sauce: From the Garden to the Jar.

Homemade Tomato Sauce (pizza, marinara)

Let’s talk sauce! In several previous posts, I have mentioned using my homemade tomato sauce. I have not shared the recipe until now; I have finally done so. 😊

My journey with tomatoes began years ago, when I harvested them from our garden. Each year, we plant a garden, and summertime means fresh, delicious, homegrown tomatoes. Tomatoes are the largest product we process (preserve).

At first, when we processed (canned) the tomatoes, nothing special, pretty basic. Then I decided that, since tomato sauce is one of the most used pantry staples, I would start making the sauce before processing the tomatoes. I will discuss preserving them in a separate post. This post is all about the sauce!!!!

Why I Preserve My Tomato Sauce

For me, canning tomato sauce isn’t just about saving money or being self-sufficient (although those are big perks!). It’s about knowing exactly what’s in our food. No preservatives. No added sugars. Just ripe tomatoes, fresh herbs, and love in every jar.

We use this sauce for everything—spaghetti night, homemade pizza, lasagna, stews, and even as a base for soups. It’s versatile, rich in flavor, and significantly better than anything from store shelves.

Let’s not forget fresh chopped tomatoes—the superstar! They’re my second must-have pantry item. I can them right alongside the sauce and use them in chili, casseroles, and any recipe that calls for a can of diced tomatoes.

A Pantry Staple That Saves the Day

Whether I’m rushing to get dinner on the table or planning a cozy Sunday supper, those jars of tomato sauce are always there to help. It’s one of the simplest ways I preserve a taste of summer—and it makes meals so much easier to pull together when I don’t feel like starting from scratch.

Plus, it’s incredibly satisfying to see shelves lined with homemade jars you filled yourself. There’s just something comforting about that.

It’s All About the Sauce

When I make tomato sauce, I will use fresh ingredients like garlic, onions, and fresh herbs from my herb garden. The smells of tomatoes, basil, parsley, oregano, and garlic that float through the house when I have a pot of sauce simmering are one of my favorite smells, next to freshly-baked bread.

What Will You Need for the Sauce?

• 2-3 quart saucepan. I always use stainless steel when doing anything with tomatoes. It’s best to use stainless steel when preparing tomatoes due to its non-reactive nature, which prevents acidic foods from altering the flavor or damaging the cookware.
• Wooden Spoon for stirring.
• A Chopper for chopping garlic and onions

How to Make the Tomato Sauce

Not Ready to Can? Here’s How I Store My Homemade Sauce Without Canning

I get it—not everyone is ready to dive into water baths and pressure canners right away. And sometimes, you don’t have enough tomatoes to justify a full day of canning. That’s okay! There are still several easy ways to store your homemade tomato sauce that will keep it fresh and ready when you need it.

• Refrigerating (Short-Term) Tomato Sauce – Store cooled sauce in airtight containers or mason jars. Use within 4 to 7 days. Great for meal prepping or batch cooking for the week.
• Freezing Tomato Sauce – This is probably the easiest method, and the one I use when I’m short on time or jars. Frozen sauce keeps well for 4 to 6 months, and it tastes just as fresh as the day you made it when thawed and reheated.
  Here is what I do:
  • Let the sauce cool completely after cooking.
  • Pour it into freezer-safe containers, zip-lock freezer bags, or vacuum bags. When using zip-lock bags or vacuum-sealed bags, I lay them flat on a baking sheet to freeze. Once frozen, they stack more easily. Don’t forget to mark the bags with the date.
  • Vacuum Sealing + Freezing – For more extended freezer storage and to reduce freezer burn. Vacuum-seal cooled sauce in vacuum-safe bags. Freeze flat for space-saving stacking. Shelf Life: Up to 1 year with proper sealing.
  • 
    ***Tip: Use quart-size bags for family servings or ice cube trays for small portions (great for soups or sauces for one!).

How I Reheat My Homemade Tomato Sauce

When it’s time to bring that homemade goodness to a recipe, I follow these reheating steps.

From the Refrigerator

If your sauce has been in the refrigerator for the

• Stovetop: Pour the sauce into a saucepan and heat over medium-low heat, stirring occasionally until it’s warmed through; this usually takes 5 to 10 minutes.
• Microwave: Transfer the sauce to a microwave-safe bowl, cover loosely with a lid or paper towel. Heat for about 30-60 seconds, then test. Continue heating until it reaches your desired temperature, stirring between each interval until hot.
  **Tip: The sauce thickens in the refrigerator; add a splash of water or broth to loosen it up.

From the Freezer

When retrieving the sauce from the freezer, I thaw it first if I’ve time — but I’ve also reheated it straight from frozen when I was in a hurry.

Two ways I do this;

• Boiling Water – If the tomato sauce has been frozen in a zip-lock bag or vacuum-sealed bag. I will fill a pot with water and let the water come to a boil. Once the water is boiling, I will place the bag unopened into the boiling water for about 10 minutes.
• Stovetop – Get a saucepan and open the container or bag from the freezer. Place the sauce in the pan over medium heat. I add a splash of water so the sauce will not scorch to the pan, and stir frequently as it thaws and warms. This can take 15 to 20 minutes.
• Microwave: Transfer the sauce to a microwave-safe bowl, cover loosely with a lid or paper towel. Heat for about 30-60 seconds, then test. Continue heating until it reaches your desired temperature, stirring between each interval until hot.
  **Tip: The sauce thickens in the refrigerator; add a splash of water or broth to loosen it up.

Sometimes when reheating, I will stir in a bit of basil-flavored olive oil, fresh basil, and salt. This will refresh and help to bring the flavor back to the forefront. However, I have learned that the longer the sauce stays blended, the flavors blend together and become delicious.

Canning Tomato Sauce

If you’re new to canning, safety is key to keeping your jars shelf-stable and safe for your family. Here are a few essential tips I always follow:

• Use only fresh, firm tomatoes. Overripe or damaged fruit can lead to spoilage.
• Know your method: Water bath canning is fine for high-acid recipes. Pressure canning is required if you’re adding low-acid ingredients like peppers, onions, or meats.
• Add bottled lemon juice or citric acid to each jar to ensure safe acidity levels.
• Sterilize jars before filling, and always use new lids to ensure a tight seal.
• Follow USDA-approved canning methods. Never “wing it” with ingredients when preserving.
• Label and date your jars, and store them in a cool, dark place.
