This year I had a BUMPER crop of tomatoes! Im talking hundreds of pounds (yay/yikes). By the end of the harvest season, we had easily eaten our weight in tomatoes. I needed a great way to use up large amounts of tomatoes so that we could enjoy them all winter long. A major bonus to this recipe is that it doesn’t require hours of skinning or straining through a food mill. The tomatoes are roasted, leaving the skins soft and easily blended without the hassle of peeling while not compromising great flavor.

Tips + Tricks
These tips and trick will help you achieve greatness whether its the first time you’ve made this recipe or the tenth!
- Roast your vegetables long enough that the skin is soft and easily crushed.
- Ensure that your tomatoes are ripe. Unripened tomatoes will be harder to combine with your other ingredients when blending.
- If you have a lot of green tomatoes, place them in a cardboard box, single layered, and close the lid. Keep them in a warm, dark place and check them frequently.
- Use this garlic tomato soup base on your favourite pasta, or as a sauce for homemade pizza.
- Use a splatter guard and simmer this roasted garlic tomato soup over medium heat for 45-60 minutes to get a thicker consistency.
Key Ingredients
- Tomatoes: Thicker sauce tomatoes such as Roma, San Marzano, and Giullietta work the best for this recipe but any tomato can be used. I used a variety of tomatoes that I had that were ripe including Marzano, Sunrise Roma, Manitoba, and some Early Girl and they combined wonderfully in this homemade canned tomato soup recipe.
- Lemon juice or Citric Acid: 2 tbsp of lemon juice / quart, 1 tbsp / pint. ½ tsp citric acid / quart, ¼ tsp / pint. This ingredient is non-negotiable in order to make your homemade tomato soup safe and shelf stable.
- Onions- cut up a few small onions or one medium onion. You don’t have to be picky about the type.
- Garlic- Peel and place whole cloves onto the pan. Roasted garlic is so aromatic and dreamy!
- Peppers- Pick fresh, firm bell peppers. If you like a bit of heat, feel free to sub the bell peppers for spicier ones like Jalapeño.
- Herbs- you can easily personalize this recipe with your choice of desired herbs. Choose dried herbs to keep your acid level in check if you are canning. Check your grocery store for organic herbs to go along with your fresh tomatoes.

A Few Golden Rules…
- You must use an acid when canning tomatoes. Adding the allocated amount of citric acid or lemon juice effectively lowers the PH of your tomatoes so that they can be safely canned in a water bath canner or pressure canner. The general rule of thumb is 2 tbsp lemon juice/ quart or ½ tsp citric acid per quart jar. Halve these amounts for pints. The acid can be added directly to your jars before filling them.
- Keep your vegetable to tomato ratio in check ✓. According to the National Center for Home Preservation, you should not exceed three cups of any combination of vegetables per 22 pounds of tomatoes. This does not include dried herbs and spices!
- If you choose to freeze this recipe, make sure that you remove as much air from your ziplock or vessel of choice before stowing them away. This will help to prevent your homemade tomato soup from getting freezer burnt and reducing the quality of it. This soup will last with optimum flavour and texture for about 4-6 months in the freezer.
- Never thicken your soup with any kind of flour mixture or cornstarch before canning- if desired, these ingredients can be added just before eating fresh.
Jar Sterilization
It’s important to sterilize your jars to prevent cross contamination during home canning. Here are a few ways you can sterilize your jars:
Boiling Water Method: Wash jars & lids. Place jars in water bath canner, covered with water and bring to a simmer (180F/82C).
Oven Method: Wash jars & lids: Heat oven to 185F, place jars in the oven (I use a clean cookie sheet to make them easier to handle) and allow them to sit for at least 15 minutes. Leave the jars in until ready to fill.
Dishwasher Method: Place jars, lids, and seals in the dishwasher on the hottest cycle. Take them out when ready to fill!

Instructions

- Roast: Place cut tomatoes on a high rack in your oven and cook for about 50 minutes. It is a good idea to switch the pans around after about 25 minutes to ensure that each pan is evenly roasted.
- Combine: Once cooking time is done, transfer all vegetables to a large stock pot. Add spices, herbs, and sugar to the tomato mixture. Blend/puree the soup to your desired consistency using a stick blender or working in small batches, place them in a food processor or regular blender.
- Cook / Reduce: Bring the tomatoes to a boil over medium/low heat and then turn down to a simmer and simmer for an hour, stirring regularly. The longer you simmer, the thicker your soup will be! You can adjust this for your preference.
- Add 1 tablespoon of lemon juice to each pint jar. Spoon soup into sterilized jars leaving an inch of headspace.
- Wipe the rims of the jars and place your warmed seals on the jar. Secure lids by finger tightening the screw bands.

- Bring canner to a boil. Once it is boiling steadily, start the processing time.
- Process pints for 35 minutes. Adjust processing times according to the table included in this post to ensure you are processing properly for your altitude.
