A lower-calorie way to make Corned beef with mustard sauce
Corned beef with light mustard sauce and broth-cooked vegetables
Lean-trimmed corned beef, cabbage, carrots and potatoes with a milk mustard sauce make a Kiwi classic at about 520 calories.
Corned beef is already seasoned and should not need a heavy buttery sauce. This method starts the brisket in fresh cold water and keeps the pot at a gentle tremble, then cooks vegetables in the aromatic broth by their different times. The mustard sauce uses trim milk and only enough flour to coat the slices; its sharpness is more important than richness.
What changes—and what stays
From often 700–900 kcal with fatty brisket, buttery white sauce and large potato portions to 520 calories
Trim a 1.6 kg corned silverside before and after simmering, serve 150 g cooked meat, and make eight portions of sauce with trim milk and 25 g butter. Bay, peppercorn and onion scent the simmer, mustard and a touch of vinegar cut the cured beef, and vegetables absorb the savoury broth directly.

How the flavor stays
Bay, peppercorn and onion scent the simmer, mustard and a touch of vinegar cut the cured beef, and vegetables absorb the savoury broth directly.
A cost rule that survives inflation
A whole silverside divides neatly for a family meal and sandwiches, while cabbage, carrots and potatoes cook in one broth without separate sauces or oils.
Ingredients for 8
Measure first; timing is part of how this recipe uses less fat.

- 900 gpotatoes
- 700 gcabbage
- 600 gcarrots
- 300 gonion
- 700 mltrim milk

Method
Each step includes heat, a visible cue, and a recovery.
Step 1 · follow the visible cue
Rinse and start in cold fresh water
Rinse the silverside, trim obvious fat and cover with cold water, onion, bay and peppercorns before bringing it slowly to a simmer.
Look for: The water is only gently moving and grey foam has been skimmed before it can cloud the broth.
Step 2 · follow the visible cue
Add vegetables by the clock
After the beef is nearly tender, add potatoes and carrots, then cabbage wedges for only the last ten to twelve minutes.
Look for: Potatoes hold their edges, carrot yields to a knife and cabbage remains pale green rather than collapsing.
Step 3 · follow the visible cue
Whisk a sharp, flowing mustard sauce
Cook flour in butter for one minute, whisk in warm milk gradually and simmer until lightly coating; add mustard and vinegar off the heat.
Look for: The sauce runs in a broad ribbon and tastes mustard-forward without a floury finish or butter layer.
Step 4 · follow the visible cue
Rest and slice across the grain
Rest beef fifteen minutes, remove the remaining exterior fat and slice thinly across the visible grain. Divide with vegetables and sauce.
Look for: Slices bend without shredding and each plate receives a narrow ribbon of sauce rather than a deep pool.

The estimate uses the listed ingredients divided into 8 servings. Brand labels, trimming, and the amount left in the pan can change the result.
Keep the leftovers in the same spirit
Keep sliced beef in a little strained broth for three days so it does not dry. Reheat gently and bring sauce separately to steaming.

Frequently asked questions
Why is no extra salt listed?
Corned beef and its broth are already salty; season vegetables only after tasting.
Can the cooking broth be used later?
Yes in small amounts for soup, but taste and dilute because cured meat can make it very salty.
