A good prep list answers one question before service starts: how much of each item do we need ready, and who is making it? Without one, kitchens tend to swing between running out at 8 pm and throwing out trays of food on Monday morning.
The fix is a list built on par levels — the amount of each prepped item you want on hand at the start of service — and a simple daily routine to top up to that par.
What a par level is
A par is your target quantity for a prepped item: marinated chicken, sauce, diced onion, dressing. Each day, the team counts what is left, subtracts it from the par, and preps the difference. Nobody has to guess, and the amount made follows how busy you actually are.
Amount to prep
Par level − What's on hand = Prep today
Set pars from your real sales
Pars work best when they come from numbers rather than memory. Your sales reports show how many of each dish you sold; your recipes tell you how much of each prepped item those dishes use. Together they give you daily usage.
Par level
Average daily usage × Days until you prep again × (1 + Safety buffer)
The safety buffer covers busier-than-usual days. Something in the 10–20% range is a reasonable place to start; adjust it after a few weeks of watching what is left over. Most restaurants also need separate pars for slow and busy days — a Tuesday par will leave you short on a Saturday.
Build the list your team will actually use
Keep it to one page per station if you can. Each line needs just enough to act on without asking anyone.
| Item | Station | Unit | Par (Fri) | On hand | Prep | Use-by (house rule) | Who |
|---|---|---|---|---|---|---|---|
| Curry sauce | Stove | qt | 12 | 5 | 7 | 3 days | Ravi |
| Marinated chicken | Grill | lb | 35 | 8 | 27 | 2 days | Ana |
| Diced onion | Prep | qt | 8 | 2 | 6 | 2 days | Luis |
| Raita | Cold | qt | 6 | 4 | 2 | 2 days | Luis |
| Chopped cilantro | Garnish | qt | 2 | 0.5 | 1.5 | 1 day | Ana |
- Order by lead time. Items that cook, cool or marinate longest go at the top; delicate items like herbs and cut fruit go last so they are freshest at service.
- Name an owner. A name next to each task removes “I thought you were doing it.”
- Leave a done column. A tick or initials lets the manager check progress at a glance.
- Post it where the work happens, not in an office.
Label and date everything
Prepping ahead only saves money if the food stays safe and good to serve. Label every container with the item, the date made and the use-by date, and rotate so the oldest product is used first (first in, first out).
The FDA Food Code, which most U.S. health departments base their rules on, requires ready-to-eat food that needs temperature control for safety — and is held for more than 24 hours — to be marked with a date. It can be kept for up to 7 days at 41°F (5°C) or below, with the day it was prepared counted as day 1.
Your own use-by times can be shorter than the legal maximum for quality reasons. Cut herbs, for example, rarely look their best after a day.
Track waste and adjust every week
A par is a starting point, not a rule set in stone. Keep a simple waste log next to the bin or walk-in: what was thrown out, how much, and why.
| Reason | What it usually points to |
|---|---|
| Over-prepped / expired | Par is too high for that day — lower it |
| Ran out during service | Par is too low, or the buffer is too small |
| Quality (wilted, dried out) | Prepped too early, or stored wrong |
| Dropped / wrong order | Training or station layout, not the par |
Once a week, look at the log alongside your sales. Adjust pars up or down in small steps and watch the next week. Seasonal menus, local events, school holidays and weather all shift demand, so expect to revisit pars a few times a year.
A simple daily routine
- Before prep starts, count what is left of each item and write it in “On hand”.
- Work out “Prep” (par minus on hand) — or let the template do it.
- Check labels and pull anything past its use-by date; note it in the waste log.
- Prep in order, top to bottom, and tick each line when done.
- Manager does a quick walk-through 30 minutes before service.
Quick checklist
- Every prepped item has a par for slow days and busy days
- Pars come from sales and recipe usage, not memory
- The list is ordered by lead time and each task has an owner
- Every container is labelled with item, prep date and use-by date
- Oldest product is used first
- Waste is logged with a reason
- Pars are reviewed weekly
