A prep list isn't a to-do list. It's a sequence. Group prep into five phases — stocks and bases, sauces and dressings, protein and marinade, garnish and vegetable, final setup — and your morning runs calm and your service starts cold. Treat prep as a flat list of tasks and you'll burn the morning, finish three things at once at 11:30, and start service half-mised. The difference between a chaotic kitchen and a calibrated one is rarely talent. It's usually the order of operations.
Why phase-based prep beats a flat list
The flat-list approach reads: "stock, mayonnaise, chop onions, brine chicken, peel potatoes, make demi, cook lentils, slice tomatoes, prep garnish..." In the order they were remembered, not the order they should happen.
Three things go wrong with this approach:
- Downstream items wait on upstream ones. Your demi-glace needs the stock. Your sauce needs the demi-glace. If the stock is mid-list, the sauce can't start until late morning — and you'll be reducing sauce while plating service.
- Equipment bottlenecks pile up. Three things that need the stove at 10am, two that need the immersion blender at 10:30, four items competing for the only ice bath. None of this is visible on a flat list.
- You never know how far through you are. "I'm 14 of 22 items done" tells you nothing useful. "Phase 1 stocks done, Phase 2 sauces in progress, Phase 3 protein not started" tells you exactly where you are and whether service is realistic.
Phase-based prep solves all three. Upstream items finish before downstream needs them. Equipment use clusters into predictable windows. Progress through phases is the actual KPI.
The five phases
Phase 1: Stocks & bases
Anything that takes 2-6 hours and produces a building block for something else. Stocks (chicken, beef, fish, vegetable), reductions, slow braises that will become tomorrow's component, fermented bases, dehydrated garnish prep that needs oven time. Start first. These should be on the stove or in the oven by the time the rest of the brigade arrives.
Phase 2: Sauces & dressings
Depend on Phase 1 outputs. Demi-glace, hollandaise base (held warm), aioli and emulsified dressings, salsas and salsa-style accompaniments, jus, infused oils. Start when Phase 1 stocks are 60-70% reduced and you can confidently pull a measured quantity.
Phase 3: Protein & marinade
Bone-out, portion, marinate, brine, dredge, sear-and-rest. This is the heavy-product phase — typically your highest food cost and where mistakes are most expensive. Schedule this for the mental peak of the prep day, usually 9-11am for a lunch service. Brining and marinating items started here will continue developing through service.
Phase 4: Garnish & vegetable
Cut, brunoise, blanch, pickle, fry crunchy garnishes, prep salad components, herb picking, microgreen handling. Lower stakes than Phase 3 (mistakes here cost less), so often a good handoff to a junior cook while you finish Phase 3.
Phase 5: Final setup
The "open the line" tasks: station inventory check, plate count to expected covers, sauce squeeze-bottles loaded, garnish trays at the pass, salt-and-spoon stations, side-towel changeover, oven preheats to service temps, induction stations on. Should take the last 20-30 minutes before service start, no longer.
Auto-generating prep from your sales forecast
The traditional prep list is dictated by the head chef at the start of the day, often in their head, sometimes on a clipboard. This works for a small kitchen with consistent menus. It scales poorly.
The structured alternative: derive the prep list from the events and à la carte covers you expect. If you have 80 covers booked, you need component quantities sufficient for 80 covers plus a 15-20% safety margin. Aggregate that demand across all menu items, expand sub-recipes (a dish needs labneh, labneh has its own recipe with its own ingredients), assign each item to its phase, and the prep list writes itself.
The mental model comes from the long tradition of European kitchen organisation — the brigade system formalised by Escoffier in the early 1900s implicitly grouped prep by station and timing, which is the same idea in a different vocabulary. Phase-based prep is the modern operational descendant of that structure.
A worked prep list
Sample for a 60-cover lunch service running a 6-item menu plus 2 specials:
| Phase | Start time | Items | ~ time |
|---|---|---|---|
| 1. Stocks & bases | 06:30 | Chicken stock (4L), beef demi reduction, slow-braised lamb (for tomorrow) | 3-4 h |
| 2. Sauces & dressings | 09:30 | Demi-glace finish, hollandaise base, Caesar dressing, romesco | 1-1.5 h |
| 3. Protein & marinade | 09:00 | Portion 80 salmon, marinate 60 chicken thighs, sear-and-rest 40 lamb chops | 2 h |
| 4. Garnish & veg | 10:30 | Brunoise mirepoix, pick herbs, fry shallot crisps, prep Caesar leaves | 1-1.5 h |
| 5. Final setup | 11:30 | Station inventory, sauce bottles, oven preheat, line briefing | 30 min |
| Service opens | 12:00 | — | — |
Total active prep window: ~5.5 hours. Phases 2 and 3 overlap partially (different cooks, different equipment), which is fine — the phases describe ordering of dependencies, not strict mutual exclusion.
The morning briefing
A 5-minute briefing at the start of Phase 1 saves an hour of confusion later. Cover:
- Expected covers — what does the floor say for today? Any large bookings (8+) flagged?
- Specials and changes — what's on/off the menu? Any 86s carried from last night?
- Phase 1 assignment — who is on stock, who on long braises, who supports Phase 1 finishes for the Phase 2 handoff?
- Phase 3 anchor — which cook owns protein? They cannot be pulled off without explicit re-assignment.
- Allergen alerts — any guest restrictions notified in advance? Coeliac, severe nut, anaphylactic?
The briefing is not a meeting. It's a 4-minute stand-up before knives go on the boards.
What goes wrong (and how to spot it)
Phase creep
Phase 1 takes 4 hours when it should take 3. Phase 2 starts at 10:30 instead of 09:30. Everything downstream slides. Symptom: by 11am you're "running behind." Cure: track actual phase end-times for two weeks; identify which phase always overruns; figure out why (one specific item, one consistent cook, one equipment bottleneck) and fix it.
Out-of-order start
Junior cook starts on garnish at 8am because "easy to pick away at" — meanwhile no one is on stocks. By the time stocks start at 9:30, service is two hours away and the kitchen is producing finishing detail with no base. Cure: hard rule that no Phase 4 item begins until Phase 1 is on the heat.
The forgotten sub-recipe
The menu says "lamb shank with labneh." Labneh isn't on the prep list. Why? Because someone wrote the prep list from the menu, not from the recipe ingredient lists. Labneh is a sub-recipe of the lamb shank dish and gets lost in the abstraction. By 12:30 the lamb is plated and there's no labneh. Cure: prep list generation must expand sub-recipes into their own components — every recipe with a sub-recipe should produce two prep list lines (the main protein and the sub-recipe component).
What this looks like in practice
In ProChefDesk
The Mise en Place tool generates the day's prep list automatically from booked events and active buffets — picks the date, aggregates demand across recipes (same recipe in two events gets totalled), expands sub-recipes (labneh appears as its own line under its parent lamb shank), assigns items to the five phases by recipe category, computes estimated prep time per item and rolls up phase totals. Check off as you go; the "remaining ~X min" stat updates live so you can see if you're on track. Print as a single-page A4 for the kitchen pinboard. Open the app and Mise en Place is under the Kitchen section of the sidebar.
The point
A prep list is the single most under-discussed operational document in a restaurant. Every kitchen has one; most are flat lists scrawled on a clipboard; very few are sequenced by dependency. The five-phase model is a small structural change with disproportionate operational impact.
Try it for one week. Group your existing prep into the five phases, force Phase 1 to start before anything else, and watch Phase 5 collapse from 45 chaotic minutes to a 20-minute calm finish. You haven't worked harder. You've just sequenced the work properly.
That's mise en place — not as a metaphor, but as an operational schedule.
