Ingredients, Substitutions & Foolproof Tips
- 2 tablespoons butter: Adds rich flavor and aids in the cooking process.
- 1 tablespoon canola oil: Prevents the butter from burning while enhancing the dish’s overall texture.
- 3 large yellow onions, peeled, halved, and thinly sliced: The star ingredient for sweetness and depth.
- 1 teaspoon kosher salt: Enhances the natural flavors of the onions.
- 3 sprigs fresh thyme leaves only: Provides a fresh herbaceous note.
- 1 tablespoon white balsamic vinegar (optional): Adds brightness and complexity to the flavor profile.
Tips for Success:
- Use fresh onions for the best flavor and texture.
- Adjust the heat as needed to prevent burning; slow and steady gives the best result.
- If using vinegar, add it during the last 10 minutes to maximize its flavor impact.
Step-by-Step Directions
- Melt the butter and oil: In a large cast iron or heavy-bottomed skillet over medium-high heat, melt the butter with the canola oil until shimmering. This foundation is crucial for caramelization.
- Add the onions and salt: Once melted, add the onions and sprinkle with kosher salt. Stir well to mix. You should hear a gentle sizzle as the onions hit the pan.
- Cook until starting to soften: Allow the onions to cook for about 5 minutes, stirring occasionally. You’ll notice them beginning to soften but avoid browning at this stage.
- Reduce heat and cover: Lower the heat to medium-low, cover with a lid, and continue to cook, stirring every 10 to 15 minutes. This slow cooking process is key to achieving the perfect caramelization.
- Add liquid if needed: If the onions begin to burn, add a splash of water or broth. Don’t worry, this is normal; embrace the pace of your cooking journey.
- Finish with vinegar (optional): In the last 10 minutes of cooking, if desired, stir in the white balsamic vinegar for added depth of flavor.
- Cook for up to an hour: Continue this process for up to 1 hour until the onions are rich, golden brown, and deliciously fragrant.
- Serve or store: Serve immediately or store in an airtight container in the refrigerator for up to one week. Get ready to enjoy!
