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.

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!

  • water bath canner
  • 6 pint sized jars with screw bands and seals
  • jar tongs
  • non-metal spatula
  • jar funnel
  • 2 large rimmed baking sheets
  • immersion blender or regular blender


  • 10 lb firm, ripe tomatoes
  • 6 tbsp lemon juice* 1 tbsp placed in each jar
  • 1 medium onion, quartered
  • 1 medium bell pepper, quartered
  • 4 cloves garlic
  • 1 tbsp italian seasoning
  • 1 tsp dried basil
  • 1 tsp salt
  • 1 tsp pepper
  • 1/2 cup packed brown sugar


  • Preheat oven to 400°f
  • Cover two large baking sheets with foil
  • Prep your ingredients: Wash all of your peppers and tomatoes. Core the tops of your tomatoes, remove the stem, seeds, and inner white flesh of your peppers. Quarter tomatoes and peppers and peeled onions and put them on the baking sheet. Trim the tip of your garlic off, peel, add to sheet.
  • 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.
  • Place the hot jars in your canner. There should be enough water to cover the jars with an inch overtop of each jar for hot water bath canning.
  • 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.
  • Remove jars slowly from your canner and place them on a heat safe surface for 12-24 hours undisturbed. After this time, store all of the jars that have effectively sealed in a cool, dark place.


This recipe can easily be doubled and tripled. If using quart jars instead of pints, increase your processing time by 5 minutes on top of the pint processing time.

    I loved grabbing for this on the shelf in my cold room. I added 1/2 cup sour cream and the texture was delightful. Cheers!

    1. Yes! This year I plan on making even more– we are almost out and there is still snow on the ground. I am glad you enjoyed it, thanks for the feedback!

    I made this last summer and enjoyed throughout the winter. It had great flavor– just added cream when I served it. I am returning for a second year to make it again- may add a bit of cayenne this time to turn up the heat as my husband and I enjoy spicy food.

    It has been rainy here for three days! I halved the batch and made this for supper with some grilled cheese. It was a winner. I added about 1 cup of heavy cream to the pot before serving. I may add noodles next time. Overall it was delicious and I will make it again.

    1. Thanks for the feedback Sarah!! I am so happy that you enjoyed it. We have also had some gloomy weather and I am here for it, soaking up some quiet slow-down time before harvest ramps up.

  4. It’s way too hot to turn the oven on to roast the tomatoes etc. Do the tomatoes and garlic have to be roasted first?

    1. Hey there, you can get around the roasting by blanching the tomatoes first and removing the skin. Without roasting I fear that the skin will be too pronounced in the recipe. Roasting softens it. In order to blanch, bring a large pot of water to a boil over high heat, drop tomatoes in for 30-60 seconds or until the tomato skins begin to crack. remove them and run them under hot water or put them on a baking sheet and allow them to cool a bit before peeling the skin off. The garlic can be minced to soften and incorporate better without roasting as well! I hope this helps 🙂
      Please let me know if it turns out for you!

  5. Question: I have a great roasted tomato basil soup recipe I just made, but it uses 2 cups of chicken stock. Would I add that with the cream after canning, or can I add the stock to the soup and then can it. Thank you so much. I was just curious bc your recipe doesn’t call for the stock.

      Hey Karolyn,
      If you are planning on canning chicken stock, it will need to be pressure canned. It is not safe to water bath can chicken stock. If you want you can definitely add a bit of stock afterward along with the cream but it will make for a thinner soup!
