Caramelized Red Onion Chutney is a sweet-and-sour relish that elevates grilled cheese, enhances a cheese board, and makes a thoughtful holiday gift. This easy chutney keeps well in the fridge and is handy to have on hand.
I also use this chutney with a no-knead caramelized onion focaccia—focaccia never tasted so good!
🧅 Why make this recipe
- It makes a lovely homemade gift and stores well;
- Perfect for grilled cheese or a cheese/charcuterie board;
- Pairs beautifully with soft cheeses like brie or goat cheese;
- Long shelf life in the fridge and can be preserved by canning;
- Lower in sugar than many chutneys—this recipe uses ⅔ cup brown sugar.
This red onion chutney is vegan and gluten-free. Made from red onions, brown sugar, balsamic vinegar, wine and spices, it develops a deep caramel color and a jam-like consistency with balanced sweetness and tartness.
This chutney is ideal for anyone who likes a touch of sweetness in savory dishes. The combination of red wine and balsamic vinegar gives the chutney just the right amount of acidity to complement the caramelized onions.
🤷🏻♀️ What is a chutney
In short, chutney is a savory jam. Key differences from fruit jam include:
- Chutneys combine vinegar and sugar for preservation, while jams commonly rely on sugar alone;
- Jams are usually fruit-based; chutneys can be made from fruit or vegetables (this recipe uses only onions);
- Chutneys are seasoned with spices and sometimes chili, offering more complex, savory flavors than most jams.
🧅 Ingredients and substitutions
Red onions: I prefer red onions for their peppery, slightly spicy profile, but yellow, white or sweet onions work too.
Olive oil: Use extra virgin olive oil to caramelize the onions.
Bay leaves, black pepper and mustard seeds: Bay leaves and black pepper add aroma and depth. Mustard seeds are optional but add a pleasant pop. Freshly ground black pepper is best.
Salt: Use fine sea salt to taste.
Brown sugar: Light or dark brown sugar both work.
Balsamic vinegar: Balsamic provides a rich, concentrated flavor—avoid substituting with plain white or red vinegar.
Red wine: Any dry red wine is suitable. If you prefer not to use wine, substitute with half red wine vinegar and half water for the same volume.
🥣 How to make it
Caramelizing the onions is the most time-consuming step but straightforward. Low and slow yields the best flavor.
Step 1. Peel and slice the onions into thin half-moons.
Step 2. In a large heavy-bottomed pan, heat the olive oil and add the sliced onions, bay leaves, black pepper and salt. Cook on low for 20–30 minutes until the onions soften and begin to caramelize.
Step 3. Add brown sugar, balsamic vinegar, red wine and mustard seeds (if using).
Step 4. Simmer on low heat for about 1 hour, stirring occasionally, until most of the liquid has reduced and the mixture is thick and dark caramel in color.
When ready, transfer the chutney to sterilized jars, let cool, seal and store in the refrigerator.
🧅 Expert tips
- You can skip pre-caramelizing by adding all ingredients at once and simmering for about 1 hour, but the flavor is best when onions are caramelized first.
- Use a heavy-bottomed pan or dutch oven to avoid burning; if using a thinner pan, stir frequently and check the bottom every 5 minutes.
- If you know how to can, you can water-bath and store jars outside the fridge until opened. Once opened, refrigerate.
🍴 What to eat with it
Serve hot or cold. It pairs beautifully with grilled cheese, soups, pizza, fresh baguette or brioche. It’s especially delicious with brie or goat cheese and makes a fantastic burger topping—try it with brie and sautéed mushrooms.
❓ Questions you might have
Yes, this recipe is vegan.
No. Substitute 1 cup red wine with ½ cup red wine vinegar + ½ cup water if you prefer not to use wine.
Not exactly. Marmalade typically refers to a bittersweet preserve made from citrus peels; onion chutney is a savory preserve and is sometimes labeled as marmalade but is, in fact, a chutney.
🫙 Storing
Flavors develop after resting, so it’s best after a day. I like to make two jars and save one to rest for a week to deepen the flavor.
Stored in the refrigerator, the chutney will keep up to 6 months. You may also water-bath can if desired and familiar with the process.
