Ah, those chopped onions… I don’t know about you, but at my place, it’s always been a little challenge. I admit, sometimes I forget to chop them finely, so the texture makes all the difference. But since I started using my Thermomix, it’s a revolution. Honestly, it’s become child’s play.
The first time I tried, I was afraid I’d end up with onion puree. But no! With the right settings, you keep that perfect texture, not too coarse, not too chopped. I speed through it, check, sometimes give it another go, just to get exactly what I want for my recipe.
And then, it’s super fast. Between the time it takes to break the onion in half and start the Thermomix, it takes 5 minutes. I swear, it’s almost longer to get out the board and knife… not to mention the tears!

Anyway, if you struggle with this, you’ll love my little guide to successfully chopping your onions with the Thermomix. We’ll see together how to make it simple, efficient, and above all delicious.
The essential ingredients to successfully chop your onions with the Thermomix
- 50 to 200 g of onions — personally, I adjust depending on the recipes, between 50 g for a small dish and 200 g when I want to prepare a good beef bourguignon.
- A bit of patience — well, this isn’t in a recipe but it’s always useful, you’ll see!
- Your trusty Thermomix — obviously, without it, it’s hard to go this fast.
Between us, I’ve already tested with different types of onions (yellow, red, white). The Thermomix works perfectly whatever the type, you just do as you like, that’s the best.

Prepare and chop your onions in a flash with the Thermomix
Honestly, no need to be a starred chef to get it right. I always start by cutting my onions in half, even though sometimes I’m tempted to put them whole (but that risks not being homogeneous). I dry them a bit if my onions are a little too juicy, otherwise the chopping can be wet.
- Place the onion halves in the bowl.
- Set the speed to 5 and the time to 5 seconds — that gives a perfect chop, no dust either.
- Check and if needed, a little extra 2 seconds is usually enough.
- Quickly clean the bowl and move on to cooking or preparing your dish.
It’s a bit like when I dose salt: I go slowly, I taste after. Same here, I prefer to check the size of my pieces, you’ll see.
Tips for cooking your onions in the Thermomix without burning them
If you like your onions soft and flavorful, but not burnt — and I am like you — then this little guide is for you. The other day, I wanted to sauté my onions without watching too closely… big mistake, they started to blacken. That was a lesson for me.
- After chopping them, pour a small drizzle of olive oil into the bowl.
- Cook at 120°C, speed 1 for 5 minutes — that’s enough in my opinion.
- To avoid sticking, I sometimes bring the onions back toward the center using the spatula.
- When they are translucent, I stop everything, not too much, not too little.
You know, it’s in these little moments that I really love my Thermomix, because it doesn’t let me down and I can get on with something else during that time.
Various uses for Thermomix chopped onions: quick and tasty recipes
I use my chopped onions for so many dishes, it’s incredible. The downside is that sometimes I have to fight with leftovers that disappear quickly.
- As a base for risotto or Bolognese sauce.
- In soups, to add flavor without too much effort.
- To sauté with mushrooms, a delight.
- For an herb and onion spread — it always surprises!
You know what? Trust yourself, try to add them wherever you want a little kick. I even sometimes put them in omelettes.
The essential equipment to chop your onions with the Thermomix
- Thermomix of course — even if it seems obvious, good maintenance makes all the difference.
- A spatula — useful to bring the onions back to the blades and not waste anything.
- A knife — for this pre-chopping step, always cut in half.
- A measuring cup — sometimes you want to measure your onions precisely, personally I prefer by eye!
Well, all this is pretty basic, but I’m sharing my experience: every little gadget counts to make life easier.
