🥄 What is Béchamel, and Why Veganize It?

Béchamel is one of the five classic French mother sauces — made from a roux (fat + flour) and milk. It’s traditionally loaded with dairy, but the good news? You can absolutely veganize it without sacrificing flavor or texture.

Lightening it up doesn’t mean losing that comforting creaminess — it just means using better, smarter ingredients.

🥬 1. Use the Right Plant-Based Milk for your Béchamelsauce

The #1 mistake in vegan white sauces is using sweetened or strongly flavored plant milk. For a light vegan Béchamel, you want a milk that’s:

• Unsweetened
• Unflavored
• Neutral in taste

✨ Top picks: Oat milk (naturally creamy), soy milk (protein-rich and stable), or cashew milk (ultra smooth). Avoid almond milk if it has a strong nutty flavor.

🧈 2. Béchamelsauce without Butter and the same texture?

Instead of dairy butter, use:

• Light olive oil
• Sunflower oil
• Vegan margarine or butter (optional for a richer version)

Olive oil adds a touch of flavor, while sunflower oil keeps things neutral and super light. Bonus: they’re both heart-healthier than butter.

🌾 3. Master the Roux (Without Overcooking It)

For a light Béchamel, you want a blonde roux — not browned, just cooked enough to get rid of the raw flour taste. Here’s how:

1. Heat your oil in a saucepan.
2. Add the flour and whisk constantly over medium heat for about 1–2 minutes.
3. Do not let it brown — stop when it’s golden and smooth.

This base gives the sauce that velvety mouthfeel without heaviness.

🥣 4. Add Liquid Gradually

Slowly pour in your plant milk while whisking constantly. This helps avoid lumps and keeps your sauce airy and smooth. Add it in batches, letting it fully incorporate before adding more.

Then, reduce the heat and let it simmer gently until it thickens to your liking — usually 10–15 minutes.

🧂 5. Season your Bechamel the Smartway

Light doesn’t mean bland. Boost flavor with:

• Salt and white pepper
• A pinch of nutmeg (classic Béchamel touch)
• Optional: garlic, onion, or a teaspoon of nutritional yeast for complexity

🌟 Pro tip: Want an even lighter feel? Add a squeeze of lemon at the end for brightness.
