There are two iconic recipes that define tomato season in my mind: the ubiquitous BLT and bruschetta.

A fresh tomato-forward bruschetta topping can be customized to include all kinds of fresh veggies, but a canned version of bruschetta needs to have a few specific ingredients if you want it to have a shelf life.

The post includes both a fresh version for immediate enjoyment and a canned version with proper acidity for shelf-stable storage. Make the fresh version when tomatoes are at their peak. Can a batch to enjoy that summer flavor all winter.

How Do You Use Bruschetta Topping?

While bruschetta is typically thought of as a spread for rustic toasts, I like to use this relish to add flavor to low carb proteins.

Here are a few of my favorite uses including a few slow carb ideas:

Topping for a low carb bun-less burger

Thick hamburger topped with tomato bruschetta relish.
Burger with peperonata topping (replace with tomato bruschetta)

Low Carb Cheese or Charcuterie Platter

Sliders for Game Days:

Other uses:

  • Mixed into scrambled eggs
  • Layered on pulled pork tostadas
  • Topping for grilled fish

How to Make Fresh Bruschetta Topping

The full instructions and ingredient amounts are in the recipe card below. In short:

  • Mash garlic with coarse salt using a knife or mortar and pestle to create a paste.
  • Combine with chopped heirloom tomatoes, pimiento-stuffed olives, jalapeños, cilantro (or parsley), olive oil, capers, lime juice, and fresh oregano or thyme.
  • Let stand 10-15 minutes to meld flavors. Serve on toasted bread or alongside proteins.

Tip: The garlic paste technique distributes garlic flavor evenly without harsh raw garlic chunks.

How to Make Canned Bruschetta Topping

The full instructions and ingredient amounts are in the recipe card below. In short:

  • Combine minced garlic, dry white wine, white wine vinegar, water, sugar, and dried oregano in a large stainless steel pot.
  • Bring to a rolling boil, reduce heat, cover, and simmer 5 minutes.
  • Pack chopped plum tomatoes into hot half-pint jars.
  • Ladle hot vinegar mixture over tomatoes, leaving ½ inch headspace.
  • Process in boiling water bath for 20 minutes.

When ready to serve, drizzle with balsamic vinegar and olive oil, and season with flaked sea salt.

For shelf-stable storage, proper acidity is essential. This version uses white wine vinegar to ensure safe canning.

FAQ

Can I use regular tomatoes instead of heirloom?

Yes. Use the ripest, most flavorful tomatoes you can find. Heirlooms have more complex flavor, but any good tomato works.

How long does the fresh relish keep?

Refrigerated, 3-5 days. The texture softens over time as the tomatoes release juice.

Can I reduce the heat?

Yes. Use fewer jalapeños or remove the seeds and membranes for milder heat. Or substitute sweet peppers.

What herbs work best?

Cilantro and parsley are both excellent. Basil is classic for Italian bruschetta. Fresh oregano or thyme add earthiness.

Is this relish low-carb?

The fresh version is very low-carb. Tomatoes, olives, and herbs are all low-carb ingredients.

    Wow, that looks fabulous. Thanks for the recipe! I will try it this weekend with my CSA box heirlooms. Unless I chow down on all of them before I get that far. I’ve been having caprese salads which really make my heart go pitty pat. So good.
