A Welcoming Introduction

Tired of store-bought bouillon cubes loaded with additives? Making your own vegetable broth cubes or paste is simple, wholesome, and incredibly versatile. Using common veggies like carrots, leeks, onions, garlic, and celery—plus salt and herbs—you can create flavor-packed cubes that last months in the freezer. Clean, vegan, customizable, and ideal for nourishing your kitchen without waste or chemicals.

Ingredients & Preparation

Gather the following high-quality ingredients:

• Vegetables: leek, carrot, celery (+ leaves), onion, garlic, shallots
• Salt: coarse sea salt (15–20% of total vegetable weight ensures preservation)
• Herbs: dried thyme, or fresh parsley/rosemary to taste
• Oil: a small amount to grease baking surfaces or molds

Clean and cut your vegetables into uniform, roughly 1‑2 cm pieces. This ensures even cooking and blending. The salt is vital for both flavor and safe shelf life—too little invites spoilage, too much overwhelms taste. Herbs bring aromatic depth, and using locally sourced or organic produce enhances both taste and sustainability.

Step‑by‑Step Method

Follow this sequence to create cubes or paste:

1. Blend the vegetables using a food processor or hand blender into a smooth purée.
2. Add salt and herbs, then blend again until fully combined and uniform.
3. Heat the mixture gently in a pot, stirring continuously until moisture reduces and it thickens into a paste.
4. Transfer onto oiled parchment paper or into molds, spreading into an even layer.
5. Cool completely, then cut into cubes or spoon into silicone molds or ice cube trays.
6. Freeze solid, then transfer to airtight containers or zip‑lock bags, separating layers with parchment to prevent sticking.
7. Label and store in freezer (up to 4 months) or refrigerate (several weeks if deeply dried). Properly frozen cubes should retain their shape and flavor when thawed for use.
