Overview
Baby leeks soften without losing their long shape when they are laid flat in the bag. Dirt can hide between the layers, so washing matters as much as trimming. This guide follows the Great British Chefs baby-leek method and keeps the smaller size explicit. Large mature leeks need different preparation and are outside this timing.

| Tender Baby Leeks | 185°F | 35 minutes |
Washed, peeled, trimmed baby leeks in one layer; the source uses 600 grams after trimming. Start timing when the bag enters the fully heated circulating bath. Check tenderness after the listed time and finish firm pieces on the stove. Serve immediately.
Choose your texture
- 185°FTender Baby Leeks
- Small leeks become tender from the outside to the center while staying whole.
Best for
- Washed, peeled, trimmed baby leeks in one layer; the source uses 600 grams after trimming.
Get it ready
- Use baby leeks. Trim the roots and tough dark green tops, then peel away damaged outer leaves.
- Rinse carefully between the layers until no grit remains, keeping the stems together where possible.
- Arrange in one layer with small pieces of butter and a little salt. Use extra bags if needed.
- Seal, submerge in the fully heated bath, and start the listed time.
Finish and serve
- Lift the leeks gently onto a warm plate and drain excess liquid.
- Check that the white center is tender with the tip of a knife. Finish any firm leeks in a covered pan.
- Coat lightly with fresh butter sauce or a warm mustard vinaigrette.
- Add crisp breadcrumbs or chopped herbs and serve immediately.
Useful tips
- Wash from the leaf end toward the root so grit flows out of the layers.
- Lay the leeks straight in the bag to make lifting them easier.
- Add crumbs at the table so they stay crisp against the soft leeks.
Common problems
- The leeks taste gritty
- Sand remained between the leaves. Open the layers enough to rinse them thoroughly before bagging.
- The white center stays tough
- Mature or unusually thick leeks were used. Use baby leeks for this timing; finish firm pieces in a covered pan before serving.

Cook safely
Wash your hands for at least 20 seconds and rinse the produce under running water before cutting. Remove damaged areas and use no soap on produce. Keep it away from raw meat and seafood, use clean equipment, and serve immediately after cooking and finishing.
The listed time is for texture; it is not a preservation method. These instructions do not cover canning, sealed storage, chilling, reheating, hot holding, or freezing. Never leave a sealed bag at room temperature.
