- 6 large onions, thinly sliced

Slow Cooker Onion Jam: The Set-it-and-Forget-it Method
Slow cookers are kitchen magic, transforming simple ingredients into complex flavors with minimal effort. Here's how to make your onion jam:

Step 1: Sauté the Onions
Heat olive oil in a large skillet over medium heat. Add sliced onions and cook, stirring occasionally, until they begin to soften and turn translucent. This step helps to kickstart the caramelization process and adds an extra layer of flavor.
Step 2: Combine Ingredients
Transfer the softened onions to your slow cooker. Add balsamic vinegar, brown sugar, salt, black pepper, garlic powder, and dried thyme. Stir well to combine, ensuring the onions are evenly coated with the other ingredients.
Step 3: Slow Cook
Cover the slow cooker and cook on low for 8-10 hours, stirring occasionally if possible. The onions will slowly break down, releasing their natural sugars and creating a rich, jam-like consistency.

Step 4: Thicken (Optional)
Once the cooking time is up, you can choose to thicken your onion jam further. If you prefer a thicker consistency, remove the lid and cook on high for an additional 30 minutes to an hour, stirring occasionally. Alternatively, you can thicken the jam by transferring it to a saucepan and simmering it on the stovetop over medium heat until it reaches your desired consistency.
Storage and Serving Suggestions
Once your onion jam has reached your desired consistency, let it cool before transferring it to an airtight container. Store it in the refrigerator for up to two weeks, or freeze it for up to three months. Here are some serving suggestions to get you started:
| Onion Jam | Pairs Well With... |
|---|---|
| On its own | Crackers, cheese, or crusty bread |
| As a spread | Sandwiches, burgers, or bagels |
| As a topping | Pizzas, flatbreads, or roasted meats |
