Cauliflower Gratin with Light Béchamel & a Hint of Grated Comté Cheese (Ideal potato gratin alternative)
By the QuiteRecipes team (Jamy & Kaïna) | Food Service Professional, Early Childhood Expert & Parents
Cauliflower baked under a light béchamel with just a whisper of Comté — the creamy comfort of potato gratin at a fraction of the carbohydrate.
Potato gratin is beloved comfort, but it isn't doing your blood sugar any favors. Cauliflower takes its place here with real grace: creamy under a truly light béchamel, crowned with a sparing grating of Comté that punches far above its weight. It's the ideal potato-gratin alternative — one that tastes like a splurge and behaves like a very low-GI side.
🥄 Ingredients
- 🫗 1 large cauliflower (about 1kg / 2 lb), cut into florets
- 🫗 1 tablespoon olive oil

- 🫗 400ml / 1 3/4 cups low-fat milk

👨🍳 Instructions
Preheat the oven to 400°F (200°C).
Steam or boil the cauliflower florets 5 minutes until just tender, then drain thoroughly.
Make the light béchamel: warm the olive oil and flour together in a saucepan for 1 minute, then whisk in the milk gradually. Simmer 3–4 minutes until thick and smooth; season with nutmeg, salt, and pepper.
Arrange the cauliflower in a baking dish, pour over the béchamel, and sprinkle with the grated Comté.
Bake 25–30 minutes until bubbling and golden on top. Rest 5 minutes before serving.
⚠️ Common Mistakes
- ✕
Over-boiling the cauliflower into mush before it ever reaches the oven.
- ✕
Baking the gratin straight from the fridge, which splits the sauce.
- ✕
Layering on the cheese — the "hint" is the entire point.
🔄 Variations
Use broccoli or romanesco in place of cauliflower.
Stir a spoonful of Dijon into the béchamel for sharpness.
A dusting of breadcrumbs over the Comté adds crunch.
🧊 Storage
- 📦
Keeps 2 days refrigerated; reheat in the oven to restore the golden top.
- 📦
Freezing washes out the texture — make it fresh.
💡 Chef Tips
Tip 1: Don't fully cook the cauliflower first — it finishes in the oven and keeps a gentle bite.
Tip 2: Comté is emphatic in flavor, so a little truly goes a long way.
Tip 3: Whisk the milk in slowly and the lumps never stand a chance.
Tip 4: Drain the florets very well; waterlogged cauliflower waters down the sauce.

Which cheese can I use instead of Comté? Gruyère or a mild cheddar works well if Comté is hard to find.
