There is more than one sensible way to approach aramelize Onions. The guide below gives 3 of them, starting with the most forgiving, and each method ends with a short check you can do in daylight.

How to use this guide

Work through the illustrated steps in order. Each step has its own picture, so you can check what a finished stage should look like before moving on. If you are short on time, skim the Quick steps box first.

What the pictures show

Every illustration depicts one real action from the step above it, drawn in the same warm 2D style so the sequence is easy to follow from top to bottom.

Who this guide is for

This walkthrough assumes you have never tried aramelize onions before. If you already know the basics, jump to the later method for the checks and fixes that keep the result consistent.

A short recap

Set up properly, work in small passes, check once in daylight, and put everything away. That is the whole of the onions — the pictures above simply show what each of those four stages looks like in practice.

Quick steps

  1. Decide what finished looks like for a wooden spatula
  2. Store a wide skillet somewhere dry
  3. Work from the middle of a wide skillet outward
  4. Keep a spare beside a wide skillet
  5. Wipe the area around a pinch of salt

Things you'll need

  • a wide skillet
  • a wooden spatula
  • a pinch of salt
  • a clean tea towel
  • a measuring jug

Step-by-step

Section 1

Method 1 of 3: Fix the Usual Problems with the onions

Step 1: Decide what finished looks like for a wooden spatula

Note the starting condition so you can tell whether the change to the onions actually helped. Set out only what this stage needs; a crowded table makes the work on the onions harder than it needs to be.

Step 1: Decide what finished looks like for a wooden spatula

Step 2: Sort the pieces of a wide skillet into groups

Put anything fragile to one side before the main work on the onions begins. A clear starting surface is the cheapest way to avoid a mistake later with the onions.

Step 2: Sort the pieces of a wide skillet into groups

Step 3: Cover a pinch of salt loosely while you wait

Keep the working area tidy between passes so nothing gets knocked into the onions. Keep your eyes on the part you are working on, not the finished idea of the onions.

Step 3: Cover a pinch of salt loosely while you wait

Step 4: Smooth the surface of a wide skillet

Watch what happens for a few seconds before repeating, since the result with the onions changes gradually. Keep your eyes on the part you are working on, not the finished idea of the onions.

Step 4: Smooth the surface of a wide skillet

Step 5: Lift a wooden spatula instead of dragging it

Change one thing at a time, otherwise you will not know what fixed the onions. Leave a little margin for a correction at the end instead of using everything on the onions now.

Step 5: Lift a wooden spatula instead of dragging it

Step 6: Keep a pinch of salt level while you work

Work at the pace you can repeat, not the pace you can manage once with the onions. Keep the steps in order the first time; the sequence does more work than any single trick.

Step 6: Keep a pinch of salt level while you work

Step 7: Compare a wide skillet with your reference

If two checks disagree, trust the slower one when working on the onions. Give it a moment to settle, since the first impression of the onions often changes.

Step 7: Compare a wide skillet with your reference

Step 8: Take a second look at a wooden spatula in daylight

If everything looks fine, still check the parts you cannot easily see on the onions. A quick comparison with the picture above keeps the onions on track.

Step 9: Check the underside of a pinch of salt

A quick comparison with the picture above keeps the onions on track. If everything looks fine, still check the parts you cannot easily see on the onions.

Step 9: Check the underside of a pinch of salt

Step 10: Store a wide skillet somewhere dry

Keep one small spare part with the finished the onions to save a future trip. Close the loop with a quick check that nothing has been left out of the onions.

Step 10: Store a wide skillet somewhere dry

Step 11: Set a reminder about a wooden spatula for later

Clean the tools before anything dries on them, or the next session with the onions starts badly. Store it somewhere you will actually find it, not somewhere merely tidy for the onions.

Step 11: Set a reminder about a wooden spatula for later

Step 12: Photograph the finished result beside a pinch of salt

Keep one small spare part with the finished the onions to save a future trip. Putting things away properly is what makes the next attempt at the onions quick.

Step 12: Photograph the finished result beside a pinch of salt

Step 13: Write one line about a wooden spatula in your notes

Keep one small spare part with the finished the onions to save a future trip. Clean the tools before anything dries on them, or the next session with the onions starts badly.

Method 2 of 3: A Slower, Safer Method for the onions

Step 14: Loosen anything stuck around a pinch of salt

If something looks different from the picture, adjust the setup before touching the onions. Note the starting condition so you can tell whether the change to the onions actually helped.

Step 14: Loosen anything stuck around a pinch of salt

Step 15: Measure the space around a wooden spatula

A calm first pass sets the tone for the whole session with the onions. Choose a time when you will not be interrupted, since a steady pace makes the onions much easier to handle.

Step 15: Measure the space around a wooden spatula

Step 16: Gather everything beside a wide skillet

Check the condition of your tools now, while fixing a problem with the onions is still easy. Work at a comfortable height, because leaning over the onions makes every movement less precise.

Step 16: Gather everything beside a wide skillet

Step 17: Let a pinch of salt rest for a minute

Move slowly through corners and edges, which is where work on the onions usually goes wrong. If resistance suddenly increases, stop and look rather than forcing the onions.

Step 17: Let a pinch of salt rest for a minute

Step 18: Turn a wooden spatula over once

Watch what happens for a few seconds before repeating, since the result with the onions changes gradually. Pause when the result starts to look right; overshooting is the common error with the onions.

Step 18: Turn a wooden spatula over once

Step 19: Work from the middle of a wide skillet outward

If the material reacts differently today, adjust the pace rather than the whole plan for the onions. Pause when the result starts to look right; overshooting is the common error with the onions.

Step 19: Work from the middle of a wide skillet outward

Step 20: Keep the pace even on a pinch of salt

Keep your eyes on the part you are working on, not the finished idea of the onions. Keep the working area tidy between passes so nothing gets knocked into the onions.

Step 20: Keep the pace even on a pinch of salt

Step 21: Hold a wide skillet steady with one hand

Small repeated movements give a far more even result on the onions than one big push. If the material reacts differently today, adjust the pace rather than the whole plan for the onions.

Step 21: Hold a wide skillet steady with one hand

Step 22: Undo one small part of a cutting board if needed

Make a note of what you would change next time before you forget the details of the onions. Compare against the goal you wrote down rather than against a vague ideal of the onions.

Step 22: Undo one small part of a cutting board if needed

Step 23: Mark anything off about a pinch of salt

One honest check now replaces three rushed corrections to the onions later. Ask what a beginner would misread here, then simplify that part of the onions.

Step 23: Mark anything off about a pinch of salt

Step 24: Label a wide skillet with today's date

Close the loop with a quick check that nothing has been left out of the onions. Putting things away properly is what makes the next attempt at the onions quick.

Step 24: Label a wide skillet with today's date

Step 25: Clear away the tools used on a wooden spatula

Close the loop with a quick check that nothing has been left out of the onions. Clean the tools before anything dries on them, or the next session with the onions starts badly.

Step 25: Clear away the tools used on a wooden spatula

Step 26: Put a pinch of salt back in its place

Decide now when you will revisit it; otherwise the habit around the onions quietly slips off the list. Repeat the same motion at a steady speed for a more even finish.

Step 26: Put a pinch of salt back in its place

Step 27: Keep a spare beside a wide skillet

Tidy the surrounding area as well, because a clear finish makes the onions feel complete. Decide now when you will revisit it; otherwise the habit around the onions quietly slips off the list.

Step 27: Keep a spare beside a wide skillet

Step 28: Let a pinch of salt settle overnight

A one-line note today is more useful than a long explanation next month about the onions. Decide now when you will revisit it; otherwise the habit around the onions quietly slips off the list.

Method 3 of 3: Get the onions Ready the Easy Way

Step 29: Put a wooden spatula within easy reach

A calm first pass sets the tone for the whole session with the onions. Put anything fragile to one side before the main work on the onions begins.

Step 29: Put a wooden spatula within easy reach

Step 30: Read the notes about a clean tea towel once

A quick dry run with no material shows you where your hands will need to go for the onions. Check the condition of your tools now, while fixing a problem with the onions is still easy.

Step 30: Read the notes about a clean tea towel once

Step 31: Repeat the same motion across a wide skillet

Move slowly through corners and edges, which is where work on the onions usually goes wrong. Keep the same hand position from one pass to the next so the result with the onions stays consistent.

Step 31: Repeat the same motion across a wide skillet

Step 32: Apply gentle pressure to a pinch of salt

Keep the working area tidy between passes so nothing gets knocked into the onions. Move slowly through corners and edges, which is where work on the onions usually goes wrong.

Step 32: Apply gentle pressure to a pinch of salt

Step 33: Pause halfway through a wooden spatula

Change one thing at a time, otherwise you will not know what fixed the onions. If resistance suddenly increases, stop and look rather than forcing the onions.

Step 33: Pause halfway through a wooden spatula

Step 34: Measure a pinch of salt a second time

Give it a moment to settle, since the first impression of the onions often changes. Look at the whole thing, not only the part you just touched on the onions.

Step 34: Measure a pinch of salt a second time

Step 35: Plan the next attempt with a wooden spatula

A one-line note today is more useful than a long explanation next month about the onions. Tidy the surrounding area as well, because a clear finish makes the onions feel complete.

Step 35: Plan the next attempt with a wooden spatula

Step 36: Wipe the area around a pinch of salt

Putting things away properly is what makes the next attempt at the onions quick. Store it somewhere you will actually find it, not somewhere merely tidy for the onions.

Tips

  • Work in daylight when you can, since small differences are easier to see.
  • Write down one thing that surprised you; it is usually the useful part. For another walkthrough, see How to Make a Smoothie Bowl.
  • Keep the finished result somewhere you will see it, which makes the next attempt easier.
  • Keep a spare cloth or container nearby for the small mess that always appears.
  • If you are unsure, do less and look again before adding more.

Warnings

  • Read any product label before use and follow the maker's instructions. Official guidance: Harvard T.H. Chan School of Public Health.
  • Never combine steps that the guide separates; the pauses exist for a reason.
