Par-Based Prep System Launch Checklist
A step-by-step checklist for taking a restaurant kitchen from prep by memory to a par-based prep list that any lead can run, in roughly a month.
Reviewed for 2026, updated September 8, 2026.
Most kitchens that switch to par-based prep do not fail on the math. They fail on the setup: an item list that is missing half the mise en place, pars copied from a busy Saturday and applied to a slow Tuesday, counts that nobody trusts, and a sheet that only one person knows how to read. This checklist walks through the setup in order, from the first item list to the first month of adjustments, so the system holds up when the person who built it takes a day off.
Work through it over a few weeks rather than one afternoon. Each phase builds on the one before it, and a par that was set before counts were honest will need to be reset anyway. If you want to check the batch math as you go, the Prep Par to Batch Size Calculator at /tools/par-to-batch-size/ uses the same par, on hand, and yield inputs this checklist asks you to gather. The full reasoning behind each step is in the guide at /guide/.
- List every prepped item by station, including sauces, garnishes, portioned proteins, and backups that are easy to forget
- Give each item one unit of measure that the whole team uses (quarts, hotel pans, each, portions) and print it next to the item name
- Record the shelf life or hold time for every item so pars for short-life items stay small
- Write down the recipe yield per batch for each item in the same unit as its par
- Set a starting par for each item based on a typical day, not your busiest day
- Decide which items get a day-of-week adjustment and note the factor for each day (for example, a higher Friday and a lower Monday)
- Add a safety buffer only where running out costs more than throwing away, and keep it out of items that spoil fast
- Define what counts as on hand: only product that is still within hold time and actually usable for service
- Fix a count time (before the prep shift starts) and one person responsible for it each day
- Arrange the walk-in and line so counting follows a fixed path and takes minutes, not half an hour
- Write the prep list in one order every day: item, station, par, on hand, need, batches, cook, and deadline
- Assign each line on the prep list to a named station and a named cook, with a time it must be done
- Post the list where the whole team can see it and check tasks off during the shift
- Log what was actually prepped and what was left at close for each item, even if it is a quick tally on the sheet
- Review overage and shortfalls at the end of each week and move pars in small steps rather than big swings
- Cost the recurring overage on high-value items with the Over-Prep Waste Cost Calculator at /tools/over-prep-waste-cost/ to decide which pars to fix first
- Check that the total prep hours the list implies fit the scheduled crew, using the Prep Shift Labor Load Calculator at /tools/prep-shift-labor-load/ if you need a quick estimate
- Run one full week where a second lead builds and runs the list from the written rules alone, and fix anything they had to ask about
- Decide where the list lives long term (paper, spreadsheet, or software) and who owns par changes
- Put a recurring monthly date on the calendar to review pars for menu changes, season, and volume shifts
