CondimentMedium · Warm
A slow-cooked, deeply caramelized jam that transforms humble garlic and onions into a sweet-savory condiment. Sol teaches this one by sound, smell, and instinct—because the pan tells you more than any timer ever could.

Method
Peel and slice your onions into thin half-moons. A medium thickness—you want them to hold some texture through the long cook, not dissolve into nothing.
Separate your garlic into cloves, peel them, and give them a rough chop. Not too fine or they'll disappear into the onions and you won't find them later. That's a flavor bomb waiting to go off.
Pour the olive oil into your pan over medium-low heat. Give it a moment to shimmer and spread, then add your sliced onions.
Toss the onions in the oil until they're all glistening and coated. You're not frying yet—you're just getting them dressed for the long haul.
After 5 minutes, push the onions aside and peer underneath. You want to see a tiny bit of liquid pooling at the bottom of the pan. That means they're sweating, not browning. This is your green light to keep going. If they're already browning, reduce heat immediately and add a splash of water to rescue them.
Continue cooking over medium-low, stirring every 3-4 minutes. The onions will slowly collapse and become translucent. This is a patience game—you're building complexity that can't be rushed.
Around the 20-minute mark, the onions should be soft, golden, and starting to stick slightly to the pan. This is the moment to add your brown sugar. Sprinkle it over everything, then stir it in.
The sugar will melt and the pan will get jammy almost immediately. This is where it gets fun—taste it. Is it too sweet? Add a squeeze of lemon. Too sharp? A pinch more sugar. This is YOUR jam. Adjust until it sings to YOUR taste.
Let everything cook together for another 8-10 minutes, stirring more frequently now. The jam should be deeply golden, thick, and jammy. You want it to coat a spoon without sliding off immediately.
Too brown too fast? Add a splash of water and scrape up the fond. Too wet? Turn the heat up slightly and keep stirring. The beauty of this recipe is you can always bring it back. That's the whole point.
Remove from heat and fish out the thyme sprigs. Let the jam cool in the pan—it will thicken as it cools. Transfer to a jar and store in the fridge for up to 2 weeks. If it lasts that long.

Frying PanSafety & Storage
Cooking Temperature
When adding brown sugar around the 20-minute mark, reduce heat slightly to prevent the sugary mixture from burning or caramelizing too quickly on the hot pan surface.
Handling
Use caution when stirring the hot jam with a wooden spoon as the mixture reaches high temperatures and can cause burns if it splatters.
Storage
Cool the jam completely before transferring to a clean, airtight container for refrigeration.
Shelf Life
Refrigerated jam maintains quality for up to 2 weeks; discard if mold appears or if it develops an off smell.
Equipment Safety
Allow the pan to cool before washing to prevent thermal shock that could damage cookware or cause injury.
Pro Tips
Technique
That moment when the onions start sticking? That's not a disaster—that's your pan telling you the Maillard reaction is working. Scrape up that fond with a splash of water and keep going. That's where the flavor lives.
Flavor Boost
Throw in a splash of balsamic or red wine vinegar right at the end instead of lemon for a deeper, more complex sweetness. Both paths lead to delicious—just different kinds of delicious.
Storage
This jam actually gets better the next day once the flavors have married in the fridge. Make a double batch and watch it disappear faster than you think.
From the chef
This jam is what happens when onions and garlic stop being background ingredients and become the whole point. You cook them low and slow — twenty minutes minimum — until the sharp bite melts out and something sweet and deeply savory takes its place. The brown sugar goes in when the onions are already golden and collapsing, turning the pan jammy almost instantly. Too sweet? Lemon. Too sharp? A pinch more sugar. The pan tells you what it needs at every stage. Spread it on bread, fold it into eggs, spoon it over grilled anything — there is no wrong use for a jar of this.
