Knife Skills
The foundation of every great cook.
- Lesson 1
How to dice an onion
The classic chef cut — fast, uniform, no tears (mostly).
- 1Slice off the stem end. Leave the root end on — that's what holds it together.
- 2Cut the onion in half through the root. Peel back the papery skin.
- 3Lay flat, cut-side down. Make vertical slices toward the root, but don't cut through it.
- 4Make 2-3 horizontal cuts parallel to the board, again stopping at the root.
- 5Slice across — perfect dice falls away. Discard the root.
Chef's tip: Sharp knife + cold onion = far fewer tears. Chill it 15 min before you cut.
Safety: Curl the fingertips of your guiding hand back into a claw — knuckles forward, tips tucked.
- Lesson 2
How to slice tomatoes
Clean rounds without crushing the flesh.
- 1Use a SERRATED knife. A straight blade slides on tomato skin and tears it.
- 2Set the tomato stem-side down on the board for stability.
- 3Saw with light pressure — let the teeth do the work, don't push down.
- 4Aim for slices about ¼ inch thick for sandwiches, ⅛ inch for salads.
Chef's tip: If you only own a chef knife, score the skin with the tip first, then slice.
- Lesson 3
How to cut peppers (no waste)
Get the most flesh out of every bell pepper.
- 1Stand the pepper on its base. Slice down each of the 3-4 'walls', cutting around the core.
- 2You're left with a stem and seed cluster in the middle — toss it whole.
- 3Lay each wall skin-side down. Trim any white ribs.
- 4Slice into strips, then crosswise for a dice. Uniform pieces cook evenly.
Chef's tip: For fajitas, slice with the grain (long strips). For salsa, dice small.
- Lesson 4
How to debone a chicken thigh
Cheaper than boneless, and you get a free bone for stock.
- 1Lay the thigh skin-side down. You'll see the bone running through the middle.
- 2Run the knife along ONE side of the bone, separating meat from bone.
- 3Repeat on the other side. The bone is now exposed.
- 4Slide the knife UNDER the bone, lifting it out. Trim cartilage at the joints.
- 5Save the bone in a freezer bag for stock day.
Chef's tip: A boning knife helps but a sharp chef knife works. Go slow the first few times.
Safety: Use a separate cutting board for raw poultry. Wash hands, knife, and board with hot soapy water after.
- Lesson 5
Proper knife safety
30 years in pro kitchens. These rules keep all 10 fingers attached.
- 1A sharp knife is SAFER than a dull one — dull blades slip.
- 2The claw grip: curl your guiding fingers back, knuckles forward, fingertips tucked.
- 3Never try to catch a falling knife. Step back and let it land.
- 4Walk with the blade pointed at the floor, edge facing your leg, never up.
- 5Wet hands or wet handles = stop and dry off. That's how people get cut.
- 6Wash knives by hand immediately. Never leave them in a sink full of suds.
Safety: Use a damp towel under your cutting board so it doesn't slide. Stable board = stable cut.
