Directions

1
Peel the onions and separate all garlic cloves, removing their skins.
2
Wash and dry the parsley, removing the thickest stems.
3
Place all ingredients in a blender and process until you get a smooth, uniform paste.
4
Transfer the seasoning into clean glass jars with tight-fitting lids.
5
Refrigerate and use as needed — it keeps well for several weeks.

💡 Chef's Tip

Use 1–2 tablespoons per dish as a base seasoning instead of fresh garlic and onion. Freeze portions in ice cube trays for longer storage and quick single-use portions.
