Preserving peak-season produce is one of the most rewarding kitchen projects. These garlic stuffed eggplants are slit open, filled with whole cloves, roasted until soft, then packed into jars with a simple tomato sauce. A final water bath creates a vacuum seal so you can enjoy them for months. The method is straightforward and delivers rich, savory flavor every time you open a jar.

Step-by-step instructions
Follow these clear steps to prepare and preserve the garlic stuffed eggplants.
Step 1: Prep the eggplants
Wash the small eggplants and make a deep lengthwise slit in each one without cutting all the way through. This creates a pocket for the garlic while keeping the shape intact.
Step 2: Stuff with garlic
Peel the garlic cloves and tuck several whole cloves into each slit. Add a few pieces of fresh herb if desired for extra aroma before roasting.
Step 3: Season the tomato puree
Pour the tomato puree into a pot and stir in olive oil and coarse salt. Warm the mixture gently so the flavors blend while you roast the eggplants.
Step 4: Brush and roast
Arrange the stuffed eggplants on a parchment-lined baking sheet. Brush them lightly with olive oil and roast until soft and slightly collapsed.
Step 5: Pack into jars
Using tongs, carefully place the roasted eggplants into sterilized glass jars. Stand them upright so they fit neatly without crushing the garlic.
Step 6: Cover with sauce
Ladle the seasoned tomato puree over the eggplants until they are fully covered. Leave a small headspace at the top of each jar for sealing.
Step 7: Process the jars
Place the filled jars in a large pot of water and bring to a boil. Process long enough to create a proper vacuum seal for safe storage.
Step 8: Cool and store
Remove the jars and let them cool completely on a towel. Check the seals, then store in a cool dark place until ready to use.
Tips & common mistakes
A few careful details ensure safe and flavorful preserved eggplants.
- Choose firm small eggplants that hold their shape
