DedInc Chef Vegetable Guide
Most home vegetable cookery fails in one of two directions: boiled into gray mush or raw-hearted and unseasoned. Vegetables are not garnish — each has a correct method and a correct doneness, and salt/fat/acid apply to them exactly as to meat.
Read references/vegetable-tables.md for per-vegetable methods, temps, and times.
Universal rules
- Water is the enemy of flavor. Flavor concentrates when water leaves (roasting, searing, grilling) and dilutes when water enters (boiling). Boil only when the water is the dish (soups) or for blanching.
- Roast hot: 200–220°C, cut evenly, tossed in enough oil to coat (1–2 tbsp per tray), in ONE layer with space. A crowded tray steams; two trays beat one pile. Salt before roasting; acid/fresh elements after.
- Brown = flavor. Maillard and caramelization apply to vegetables fully. Pale roasted vegetables are unfinished.
- Blanch green vegetables in aggressively salted boiling water (10 g/L) for minutes, then ice/cold-rinse to lock color. Add acid only at serving — acid + time turns greens olive-drab.
- Cut size = cooking method. Big chunks for long roasts/braises, small dice for quick sautés and soups. Mixed sizes = mixed doneness.
- Stagger by density when combining: onions/carrots/roots first, peppers/zucchini mid, greens/garlic/peas last.
- Season vegetables like they matter: salt during cooking, acid at the end, and a finisher (butter, good oil, nuts, herbs, cheese) on anything served as its own dish.
- Doneness target: tender with a remnant of resistance. If a fork meets zero resistance anywhere, you're in mush territory (except deliberate purees/braises).
Method-selection logic
- Want a side that tastes premium with zero skill → roast at 210°C until deeply browned (cauliflower, broccoli, carrots, potatoes, squash all transform).
- Want speed → hot sauté/stir-fry with staged additions.
- Want soup → sweat aromatics in fat first (never just boil everything from cold — sweating builds the flavor base).
- Want freshness → raw/quick-pickle: salt + acid + 15 min does wonders for onion, cucumber, cabbage, radish.
- Want silk → braise (cabbage, leeks, fennel, green beans "southern style") — the deliberate exception to "don't cook long".
- Potatoes are their own science: starchy (baking, mash, fries) vs waxy (salads, boiling); never mash in a food processor (glue).
Frozen & preserved
- Frozen peas/corn/spinach are excellent — often better than tired fresh. Do NOT thaw before cooking (except spinach: thaw + squeeze hard).
- Frozen "stir-fry mixes" water everything down — roast from frozen at 220°C or accept the compromise.
- Sauerkraut/pickles are flavor ingredients, not just sides: brines = acid seasoning.
Rescue table
| Problem | Fix now | Prevent next time |
|---|---|---|
| Soggy roasted veg | Hot oven 230°C 5–10 min spread out | Less crowding, dry veg, hotter oven |
| Gray green beans/broccoli | No rescue; garnish strategy | Blanch + shock; acid only at serving |
| Bland soup | Salt %, then umami (tomato paste, parmesan rind), then acid | Sweat aromatics first, season in layers |
| Bitter eggplant/zucchini burn | Cut off char, restart heat lower | Medium heat, more oil for eggplant |
| Watery sauté | Drain, then hard heat to evaporate | Hotter pan, smaller batches, salt later (mushrooms) |
