This Tomato & Red Onion is inspired by a scrumptious onion jelly we used to eat at a local favorite restaurant.
My husband and I used to enjoy the Onion jelly and crackers at one of our favorite local restaurants. We often stated that we were going to learn to make it. I’ve put a twist on it by adding tomatoes and making it into a Burger Sauce!
Although there is a sweetness to it, My Red Onion & Tomato Jelly is perfect for bruschetta or as a topping on your favorite sandwich or burger. You might even enjoy it as a meat sauce. We slathered it on top of our grilled burgers for the perfect Tomato & Onion Jelly Burger!
Printable Recipe Below
Start by caramelizing two large red onions thinly sliced in about a half stick of melted butter. We want nice well caramelized onions so this may take a good 15 to 20 minutes on medium heat.
Then deglaze the pan with a few drops of Balsamic Vinegar and add in one thinly sliced Honeycrisp apple. Oh, yes the apple is a not so secret ingredient! Continue to cook until the onions and apples are nice and thick.
***Follow our Saucy Secrets Board on Pinterest***
The caramelized onions and apple should look nice and caramel in color and thick enough to hang on to a wooden spoon as shown.
In a bowl, combine both cans of Tuttorosso® Tomatoes and stir in the spices. Do not drain the tomatoes. I crushed up the plum tomatoes in my hand and removed the hard stem end piece.
Add the tomato mixture to the skillet into the onions and apples. Then stir in the sugars and lemon juice along with the cider vinegar. Bring to a boil then turn down to medium heat.
Simmer stirring often until mixture cooks down and begins to jell, about 2 hours.
I canned three pints which will get us through the summer nicely. Once you open a jar, store in the refrigerator. An open jar will keep for a few weeks in the refrigerator.

That burger looks like it may be the most delicious thing in the world! I’ve never tried a tomato onion jelly but if it is even partially as tasty as it looks, I think I would just LOVE it. Thanks so much for sharing this delicious recipe, I’ll be giving it a try soon and I’ll let you know how it is!
Leslie says
I can so see this on the menu of a fancy cafe or sandwich bar, I love finding unusual “condiments” such as this one that adds a kick to the dish and leaves you wondering ” what was that I just took a bite off?” Thanks for the recipe, I’ll give this one a try.
Christy Hoover says
I am loving your tomato and red onion jelly. I looked at the steps a few times so when I make it, I can kind of have the gist of which direction I need to take next. I would even pour this on a polish dog. It just looks delicious.
Cynthia L says
There is nothing better than the scent of caramelized onions! They taste pretty good too. I have never heard of a tomato and red onion jelly, but it sounds really good. I think I will have to give this a try. Your burger looks mouthwatering!

NADEEN WHITE says
Great giveaway and neat recipe! Funny- I love the flavors of onions but not actually cooking or eating them so I usually use onion powder. This looks so good though.
christina says
I am not sure if I would put that on a burger, but I definitely would put in on bruschetta. That sounds delicious!
I have never ventured into canning, but I am intrigued and am planning on checking out the youtube station, thank you for sharing!

Kristen from The Road to Domestication says
Sounds YUMMY! We’re on a low-carb/low sugar kick over here! Ever substituted another kind of sweetener for the sugars in this?
Reginia Cordell says
This is my first time hearing of tomato, red, onion, jelly. I’d imagine that it has a bit of a kick to it. I’d love to spread it on sour dough bread with a nicely grilled breast. Yum!
Becky Fry (mysparklinglife.com) says
This sounds like something my hubby would love. It sounds easy to make, I think I’ll make this for him the next time we have burgers! I’ll have to keep a jar on hand for our get togethers this summer, it’s sure to be a big hit..thanks for the recipe!
Sage says
This looks delicious, I love the idea of adding an apple to it! It reminds me of a onion chutney I had at a Pub last time I was in London. I’ve been meaning to try to recreate it, but haven’t gotten around to it, but now maybe I will 🙂 Thanks for posting!
Kallee says

It’s actually very tasty and a good substitute for ketchup. You will have to give it a try, make a small batch.
Krista says
Wow! I’ve never heard of tomato & onion jelly, but now I’m glad I have! This sounds delicious!
Shirley Wood says
You’ll have to give it a try sometime Krista. You might be surprised how good it is. Don’t think of it as a traditional jelly though. It’s a good substitute for ketchup on burgers.
Terry says
Tomato and Red Onion Jelly brings me back many years. My Mother used to make something just like this when I was a kid. What a wonderful blast from the past. And thank you so much for the recipe.
Shirley Wood says
Now you have a recipe and you can make our own. Maybe it will be something similar to the taste from your mothers recipe. I hope so. Be sure to spiralize those onions and apple!
Natalie says
This looks SO good! I’ve never had an onion jelly before, but I definitely need to try it. I am a huge fan of savory jellies (like pepper jelly)–putting this on the list of things to cook! 😀
Shirley Wood says
I made pepper jelly last year and loved it. We used our own peppers that we grew in hanging baskets on the front porch. This Tomato & Red Onion jelly is probably right up your alley!
Fi Ní Neachtáin says
Oh sweet Lord, how delicious does your burger look! I don’t think I’ve ever had an onion and tomato jelly on a burger but it looks amazing! Thank you for sharing the recipe because I definitely have to make this during the week, perfect for a treat dinner!
Shirley Wood says
It is perfect for a treat dinner! I am going to have to make another batch soon as our first batch has almost all disappeared already. It’s a nice change from the traditional burger or sandwich toppings.
Alli says
Your tomato and red onion jelly looks like something I would LOVE! I don’ t think I’ve ever made it. I make Pepper Jelly all the time and I’m definitely going to try this. Hope you had a great weekend!
Shirley Wood says
I like to make pepper jelly too and smear it on top of pork tenderloin or my Bacon Grilled Cheese with Pepper Jelly!
This Tomato & Red Pepper Jelly is not hard to make at all, it just takes some time. Hope you get to give it a try for your family.
Shirley Wood says
Ashley, you can definitely use fresh tomatoes as well. I may try it that way this summer too. So far, it’s a big hit with everyone who tastes it and I already need to make more. It can certainly be showcased at our Summer picnics and cookouts.
Ashley ~ 3 Little Greenwoods says
Oh my goodness! This recipe looks awesome and perfect for a delicious summer cookout party. We have a ton of tomatoes in our garden so I’m pinning this recipe in hopes to use it this summer!
