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.

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.

  21. 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.

We enjoying hearing from you!
