About this recipe
Leftover Vegetable Stock Thermomix TM7 is the smartest way to turn vegetable scraps and forgotten greens into a fragrant, golden broth. Searching for a homemade vegetable stock recipe that saves money and cuts food waste? This one collects mixed leftover vegetables, onion, fresh mushrooms and garlic cloves, then lets the all-in-one kitchen machine do the work: no peeling precision, no endless chopping board sessions, no watched pot on the stove. Bay leaves, whole allspice berries, peppercorns, fresh thyme and rosemary slowly release their aromas while the TM7 simmers everything gently and hands-free. The result is a clear, deeply savoury stock that beats any shop-bought cube and serves as the backbone of countless soups, risottos and sauces. It is also an excellent meal prep basic for batch cooking, portioning and freezing, ready whenever a quick weeknight dinner needs a flavour boost. Budget-friendly, vegetarian and endlessly flexible with whatever your fridge holds.
Preparation tips
- Roughly break or tear the larger leftover vegetables so they release their flavour evenly; there is no need for neat knife work because the TM7 chops everything anyway. Avoid adding cabbage, Brussels sprouts or broccoli stalks in large amounts, as they can turn the stock bitter.
- For a crystal-clear broth, strain the finished stock twice: first through a coarse sieve, then through a fine sieve or clean tea towel. Let it cool completely before portioning into jars, ice cube trays or freezer bags for up to three months.
- Salt the stock lightly at the end rather than the start, so you stay flexible when using it in sauces or risotto later. Mushroom trimmings and onion skins add wonderful colour and umami depth, so definitely keep those from your prep waste.
Recipe variations
- Asian-inspired variation: omit the rosemary and allspice, and add a piece of fresh ginger, a stalk of lemongrass and a strip of orange zest to the leftover vegetables for a fragrant stock perfect for noodle soups.
- Roasted variation: caramelise the onion and mushrooms in a hot oven beforehand for a darker, sweeter and deeper-coloured stock with a rich umami character, ideal as a base for French onion soup.
Thermomix TM7 Benefits
- Weigh your leftover vegetables directly in the mixing bowl with the built-in scale, so the onion, mushrooms and herbs go in the pot without dirtying a single kitchen scale. [Built-in Scale]
- Onions and garlic cloves are chopped finely in seconds by the TM7, releasing their savoury aroma into the stock without any hand cutting or tears. [Multi-Function]
- The TM7 grinds the whole allspice berries and peppercorns briefly, unlocking far more flavour than leaving them whole in the simmering broth. [Multi-Function]
- Precise heating keeps the vegetable stock at a gentle simmer, so the bay leaves and thyme infuse slowly without the broth turning cloudy or bitter. [Precision Control]
- Everything simmers hands-free with automatic stirring, meaning the mushrooms and rosemary steep evenly while you tidy the kitchen or prep tomorrow's meal. [Hands-Free]
