What does it mean to "blanch" a vegetable?

"Blanching" is a French culinary technique which results in vibrant, al dente vegetables that are absolutely delicious and beautiful. Blanching means that you boil your fresh, seasonal vegetables for just a few minutes before plunging them in ice water to preserve their vivid color.

Do I really need to blanch each vegetable separately?

Yes, and it is worth the extra few minutes. Different vegetables have different blanching times, and cooking them together means some will be overdone while others are underdone. Think of it as a short assembly line ,each vegetable gets its moment in the spotlight, then moves to the ice bath while the next one goes in.

Can I blanch vegetables ahead of time?

Absolutely — this is one of the best things about blanching. Blanched vegetables can be stored in an airtight container in the refrigerator for up to 2 days. This makes it a wonderful technique for dinner party prep. Just dress or warm them at the last moment before serving.

Can I use frozen vegetables for blanching?

Frozen vegetables are often already blanched before freezing, so a second blanch is generally not needed. This technique is best suited to fresh, seasonal vegetables where you want to preserve maximum color, flavor, and texture.

What other vegetables can I blanch?

Nearly any vegetable can be blanched. Asparagus (2–3 minutes), green beans (3–4 minutes), broccoli florets (2–3 minutes), and haricots verts (2 minutes) are among the most common in French cooking. The rule of thumb: the thicker and denser the vegetable, the longer the blanching time.

Notes

Blanched vegetables are incredibly versatile. Here is how we use them in our kitchen most often:

Serve Them Simply

Arrange on a platter, drizzle with good olive oil, a sprinkle of fleur de sel This is a classic French assiette de légumes and it is stunning in its simplicity.

Toss with Butter

Le Chef finishes blanched vegetables with a small knob of butter and a pinch of sea salt in a warm pan, just enough to coat them and add richness. This is the technique that makes restaurant vegetables taste different from home vegetables.

Add to Salads

Blanched vegetables hold their color and texture beautifully in composed salads. They pair wonderfully with a champagne vinaigrette or a simple Dijon mustard dressing.

Add to your Slow-Cooked Dishes

Adding blanched vegetables to a Navarin D'Agneau Lamb Stew or a Coq au Vin makes for a more beautiful presentation and a welcome variation of textures and flavors. Spring vegetables are too delicate to be put in the oven for hours - blanching renders them sublime and the sauce naturally heats them back up when you are ready to serve.

Make Ahead for Dinner Parties

Blanch up to 2 days in advance and store covered in the refrigerator. This is one of my favorite dinner party strategies, the vegetables are done, one less thing you need to concern yourself with before your guests arrive and all you need to do is dress them before serving.
