Long’s Yellow Tomato Soup

By Ann Fulton

Jump to Recipe

A delightful summer soup with a stunning color and a hint of optional heat. Yellow tomatoes are also a lower acid tomato with lots of natural sweetness.


The mere description of this soup inspired me to plant yellow tomatoes in our backyard garden. The first year, I think I got three.  

The second summer, I barely squeezed out enough to make the soup. Last summer, I finally hit pay dirt.  

It just took until early September for the plant to mature. So though I made a couple of batches of this velvety, golden soup, I put the recipe on the back burner (pardon the pun) until this summer so everyone could take full advantage of the growing season.

The recipe is a family favorite of Michael Long. Michael was my first editor at LNP and has long had more success than me with his yellow tomato plants!  

After hearing him talk so lovingly about his annual ritual of making and canning this soup, I had to try his recipe – and he kindly obliged.

The recipe starts with roasting the veggies. This process further sweetness and develops the flavor of the vibrant vegetables.

The soup is meant to be a warm soup, and we eat it that way. One of my twists on Michael’s recipe, however, is to serve the warm soup gazpacho-style, accompanied by bowls of optional toppings like chopped avocado, crumbled bacon, lump crabmeat, or goat cheese.

Those who enjoy cold soup could absolutely serve it that way. 

We’ve also added diced chicken. That said, the soup is delicious on its own; the extras simply make it a heartier, stand-alone meal. Great with a piece of crusty bread too.

True to the creative cook and writer that he is, Michael shared his treasured recipe with me in free-flow form. For those who prefer precise amounts and details, I offer them in the printable version.  For those who enjoy winging things in the kitchen, I saved Michael’s original recipe and included it below the print option.  

It’s a delightful read.

After the recipe, Michael detailed his summer adventures with his boys, then 5 and 8, from piano and drum lessons, science camps and plenty of pool time. They had just finished reading Roald Dahl’s “The BFG” and “Matilda” was next, plus they were eagerly awaiting the first eggs from their backyard chickens.  Best of all, he described the giant millipede and red spotted newt down they spotted at Tucquan Glen, and a five-foot rat snake over at Lake Grubb.

An editor who shares recipes and mentions life’s fun details to a new writer – how lucky was I? He finished his email with this: “Being a father of boys this age is just one magical experience after another.  I keep waiting for that metaphorical shoe to drop, but it just doesn’t. Life is pretty great.”

Doesn’t it make you want to squeeze just a little bit more out of these waning days of summer?

A delightful summer soup with a stunning color and a hint of heat if you like.

Michael’s original recipe note:

Happy summer, Ann.  I trust the sun is warming the spirits in the Fulton household?
Here at the Long compound, the yellow tomatoes are starting to fill out on the vines (finally! such a late growing season), and it’s time to make good on my promise to you.
So here is the recipe for yellow tomato soup, as best I can recall.

Halve and clean enough yellow tomatoes to fill a half sheet pan (13 by 18). Place them skin side up. To each tray, add: half of a large red onion, one medium-size hot pepper, any variety (to taste), halved and cleaned; one red bell pepper; two cloves of garlic.

Brush everything with olive oil, salt lightly and stick in the oven at 375 for a half hour or until the skins pop off easily.  Take out the tray and allow to cool for a few minutes before removing the skins from the tomatoes and peppers. 

There will be plenty of juices on the tray that you can strain and freeze for veggie stock.  Two trays of tomatoes makes a nice size pot of soup; three trays makes enough to can.

Dump the tomatoes and veggies into a large soup pot and add, per tray:
16 ounces of chicken stock
1 tablespoon of chopped fresh oregano
and two pieces of bacon, well-cooked and crumbled up fine
[For the vegetarians (I do not stand among them; judge me as you will), use vegetable stock, skip the bacon and add a little salt.]

Process with a hand mixer. I like this soup pretty fine.  Bring to a boil and let simmer for 20 minutes.

That’s it.  Add a little cream if you like.

Because the tomatoes are so mild, it’s a versatile soup that you can accent any number of ways.
I hope you like it. We do.😋

Long's Yellow Tomato Soup
A delightful summer soup with a hint of heat if you like.

Yield: 1 1/2+ quarts
  • 3 pounds yellow tomatoes (I used half regular yellow tomatoes, half yellow cherry tomatoes)
  • 1 red bell pepper, seeded and quartered
  • 1 hot pepper, halved (any variety; see notes*)
  • 1/2 a medium to large red onion, peeled and cut into quarters
  • 2 garlic cloves, peeled
  • 3 tablespoons olive oil
  • 1/2 teaspoon each kosher salt and freshly ground pepper
  • 2 pieces bacon, chopped**
  • 1 (14.5-ounce) can chicken broth (start with 1 cup)
  • 1 tablespoon chopped fresh oregano (or 1 teaspoon dried)
  • Optional:  cream, or various toppings such as extra crumbled bacon, chopped avocado, a sprinkle of fresh herbs, goat cheese, lump crabmeat, or even chopped chicken
  1. Preheat the oven to 375 degrees F.
  2. Cut the yellow tomatoes in half; if using, you may leave the cherry tomatoes whole.  Three pounds will be enough to almost fill a half sheet pan. Place the cut tomatoes skin-side up.  Add the bell pepper, hot pepper (skin-side up for the peppers), onion, and garlic.  Brush everything with olive oil, sprinkle with salt and pepper, and bake for 30 minutes or until the skins pop off easily.
  3. Remove the tray from the oven and allow to cool for a few minutes before removing the skins from the tomatoes and peppers.  (I find the tomato skins pop off easily after 30 minutes in my oven; the peppers less so.  I remove the pepper skins that come off easily and leave the rest on.  You may leave the skin on the cherry tomatoes, if using.)
  4. There will be plenty of juices on the tray that you can strain and freeze for veggie stock.
  5. In a large soup pot, sauté the chopped bacon until crisp.  Transfer the roasted tomatoes and veggies to the pot.  (I add all the liquid; Michael reserves the juices and then strains and freezes for later use in vegetable stock.) Add 1 cup of chicken broth and the oregano.  Process until smooth with an immersion blender or in batches in a regular blender.  If using a regular blender, return the soup to the pot.  Add more broth to achieved your preferred consistency.  The last time I added an extra 1/2 cup.  Bring the soup to a boil, and then reduce the heat and let simmer for 15-20 minutes.  Check for seasonings; you may wish to add a little extra salt depending on the type of broth used.  For a creamier, richer soup, Michael sometimes stirs in a little cream at this point.   Serve immediately with optional toppings or allow to cool and then cover and refrigerate.  The soup will keep in the refrigerator for approximately 1 week, is delicious reheated, and may be frozen.
  • *I often use a banana pepper (which has a tangy flavor and mild heat) and leave the seeds in for a level of spiciness similar to a medium salsa.  If you prefer no heat, remove the seeds and the veins. You may reserve some of the seeds and add back, to taste, if desired.  Feel free to use your favorite variety of hot pepper.
  • **For a vegetarian option, use vegetable stock, skip the bacon, and add a little more salt.

    I made this last year when we had an abundance of yellow tomatoes. We just thawed out a jar and had it for lunch. It kept beautifully and was just delicious. I think we enjoyed it even more out of season, as it was such a treat to have such a fresh tasting tomato dish in November. My husband just said it may be his favorite soup. Looks like I am going to have grow more yellow tomatoes to put up this soup for the freezer next year. Thank you for such a great recipe!

      Hi Colleen, How wonderful to have a taste of summer now that the weather is cold. I’m delighted the soup has risen to the top of the favorites list and appreciate your thoughtful feedback!

    I made this lovely soup for the second time last night and felt compelled to leave a comment. Roasting the vegetables brings out so much flavor and I use my immersion blender which couldn’t be easier. Tomato season may be soon over, but I will for sure be making this soup again next summer.

    I’ve prepared this soup three times, due to an abundance of yellow tomatoes. We love it, but the preparation was tedious. I’ve started running the roasted tomatoes through a food mill, skipped the first step of frying bacon pieces (they don’t purée well!) and added bacon, croutons, and avocado as garnish. From the looks of my pantry, we’re not on our last batch just yet!

      I’m delighted you’ve made this recipe three times, Ann – and still have plenty of tomatoes this late in the season! Thank you for also mentioning your method of preparation.

    Lovely stories from Mr Long.
    The soup is delicious!
    I used a jalapeño to give it that kick we like!

  5. Sheri Lichtenstein

    Delicious! I cut the bacon down to one thick slice of Neuske’s, and finished the soup with a little cream and a sprinkle of Salish Alderwood smoked salt.

  6. Stacy

    Love this ! I’ve made it last year also. I tweaked it just a tad. I add a small splash of Moscato to the soup. Absolutely delicious! Instead of the hot pepper I had a touch of cayenne.

      Hi Sandi, I have not frozen this soup but have frozen other tomato soup recipes. It should be fine for at least three months. As time passes, tomato soups and sauces can seem thinner once thawed. If that happens, I just simmer them for a few extra minutes to thicken.

    This soup was super tasty. I got a bunch of yellow heirloom tomatoes from our local farmers market. I used my choper to process the soup, obviously not the best, but it was DELICIOUS! To thicken the soup, we used butter in various stages of the soup making process – about a half a stick in the whole dish. Everything was a amazing. We also made some amazing grilled cheese to go with our soup.
    Thanks for giving us the recipe

      Sarah, I’m delighted the soup was a hit and appreciate your comment. Your mention of grilled cheese sandwiches on the side makes me hungry for both!

    Perfect recipe for us… I just brought in approx 15 lbs of tomatoes from three plants. I was wondering what to make with the small yellow tomatoes – they look exactly like the tomatoes in your photo. I will be making this when more of them ripen. Thanks!

    Just finishing this soup with yellow tomatoes from my garden. I did include chicken stock and bacon. However, the bacon – just two pieces – is overwhelming; OG bacon from Costco. Added 1 tsp ea coconut nectar and Braggs to cover the bacon. Didn’t help. Good soup otherwise, freezing for winter.

    1. Ann Post author

      Hi Pam, Thank you for the feedback and I’m sorry you found the bacon flavor to be overwhelming. I haven’t had that issue. Could the bacon have been a flavored variety of some sort? I’m not familiar with OG bacon.
      Update: my son just clarified the OG part ; )

      Mary, I haven’t canned this soup but Michael does every year. As long as you follow proper canning guidelines, the recipe as written should can well. Enjoy!

    1. Ann Post author

      Hi Thad, Michael has canned this but I never have-and I don’t pressure can, so I can’t speak from experience. I did consult a similar recipe, however, which calls for processing at 10 pounds of pressure for weighted gauge and 11 pounds for dial gauge, for 25 minutes for pints or half pints.

    Was wondering what to use my homegrown yellow tomatoes for as I had so many! Just made this soup and was pleasantly surprised how good it was and loved the colour of it too.Thanks for recipe.

      My yellow tomato plant has been prolific this summer, too! I’m glad you found the recipe and enjoyed it. The pretty color is an added bonus!

    Hi Ann!

    Thanks for sharing the recipe for Long’s Yellow Tomato Soup! I was skeptical as I have never cooked with yellow tomatoes! I made it following your directions and it turned out great! Its definitely a keeper! Thanks again! Kim Crowe
