Ingredients

• 2 medium (about 300g total) sweet onions
• 3 tablespoons apple cider vinegar
• 2 tablespoons tamari (gluten-free soy sauce)
• 2 large garlic cloves
• 2 tablespoons olive oil
• 1 teaspoon dried mustard powder
• 1 teaspoon paprika
• 0.25 teaspoons xanthan gum (optional, for thickening)
• 1.5 cups water
• 0.5 teaspoons salt

Directions

Step 1

Peel and thinly slice the sweet onions and garlic cloves.

Step 2

Heat 1 tablespoon of olive oil in a medium saucepan over medium heat.

Step 3

Add the onions and garlic to the pan. Sauté for 10-12 minutes, stirring frequently, until the onions are soft and beginning to caramelize. Reduce heat if they start to brown too quickly.

Step 4

Deglaze the pan by adding the apple cider vinegar, scraping up any browned bits with a wooden spoon.

Step 5

Stir in the tamari, mustard powder, paprika, salt, and 1 cup of water. Mix well.

Step 6

Bring the mixture to a gentle simmer and cook uncovered for 15 minutes, stirring occasionally. If the mixture begins to dry out, add an additional 1/4 cup of water as needed.

Step 7

Remove the mixture from heat and allow it to cool slightly.

Step 8

Transfer the cooled mixture to a blender or food processor. Blend on high speed until the sauce is smooth and creamy. For an extra-thick sauce, add xanthan gum and blend again until fully incorporated.

Step 9

Taste the sauce and adjust seasoning if necessary. If desired, you can blend in the remaining tablespoon of olive oil for extra richness.

Step 10

Store the sauce in an airtight container and refrigerate for up to 1 week. Serve as a topping for grilled proteins, a dressing for salads, or a dip for roasted vegetables.
