Recipe Information
Ingredients
- 2 medium Vidalia onions (or any sweet onion)
- 2 tablespoons Butter (unsalted)
- 1 teaspoon Minced garlic
- 2 tablespoons Low-carb sweetener (like erythritol or monk fruit)
- 1 tablespoon Apple cider vinegar
- 1 tablespoon Soy sauce (or coconut aminos for gluten-free option)
- 1 cup Water
- 1 teaspoon Salt
- 0.5 teaspoon Black pepper
- 0.25 teaspoon Xanthan gum (optional, for thickening)
Instructions
Peel and finely chop the onions into small pieces for a smoother sauce texture.
In a medium saucepan, melt the butter over medium heat until bubbling.
Add the chopped onions to the pan and cook for 8-10 minutes, stirring occasionally, until they soften and begin to caramelize.
Stir in the minced garlic and cook for another 1-2 minutes until fragrant.
Add the low-carb sweetener, apple cider vinegar, soy sauce (or coconut aminos), and water to the saucepan. Stir to combine.
Season with salt and black pepper, and bring the mixture to a gentle simmer.
Let the sauce cook for 10 minutes, stirring occasionally, until slightly reduced and flavors are well combined.
For a thicker sauce, whisk in the xanthan gum and continue cooking for an additional 1-2 minutes, ensuring no lumps form.
Allow the sauce to cool slightly before serving. Store leftovers in an airtight container in the refrigerator for up to 5 days.
