How to Make Sweet Onion Sauce

Step 1: Prepare the Onions

Start by peeling and finely chopping two large sweet onions. The smaller the chop, the smoother your sauce will be, but you can also leave some pieces chunkier for texture.

Step 2: Sauté the Onions

Heat two tablespoons of olive oil in a pan over medium heat. Add the onions and a pinch of salt, cooking slowly until they become soft and golden, about 8-10 minutes. Stir occasionally to prevent burning and encourage caramelization.

Step 3: Add Flavorings

Mince two cloves of garlic and add them to the pan with the onions. Cook for another minute until fragrant. Then add two tablespoons of honey or brown sugar and stir well to meld the sweetness into the onions.

Step 4: Deglaze with Vinegar

Pour in three tablespoons of apple cider vinegar to deglaze the pan, scraping up any browned bits. This step introduces a bright tang that balances the rich sweetness perfectly.

Step 5: Simmer and Adjust

Add a quarter cup of water or broth to thin the mixture to your preferred consistency. Let the sauce simmer gently for 5 minutes, allowing the flavors to blend harmoniously. Season with salt and black pepper to taste.

Step 6: Blend for Smoothness (Optional)

If you prefer a silky texture, transfer the sauce to a blender and pulse briefly. For a chunkier sauce, simply leave it as is and serve warm or at room temperature.

Pro Tips for Making Sweet Onion Sauce

• Choose the right onion: Sweet onions like Vidalia or Walla Walla work best for natural sweetness.
• Low and slow cooking: Caramelize onions over medium heat to avoid bitterness and develop deep flavor.
• Taste as you go: Adjust sweetness and acidity gradually to suit your palate.
• Use a non-stick pan: Prevents onions from sticking and burning, ensuring even cooking.
• Make extra sauce: It stores well, so double the recipe for easy future meals.
