Method

Blanch the green¹ beans for 4 minutes in salted boiling water, then drain and rinse with cold water.
Slice half the onion³ into thin rings, toss in a little flour, and fry in sunflower oil for 3–4 minutes until golden and crispy; drain on paper towels.
Chop the mushrooms and sauté in butter² with the remaining onion³ for 6 minutes; stir in the rest of the flour, add the cream⁴, and simmer for 2–3 minutes until thickened. Season with salt and pepper.
Mix the beans into the sauce and transfer to a baking dish.
Sprinkle with breadcrumbs and crispy onions³, then bake at 375°F (190°C) for 15 minutes until golden brown.

Tips

Why it works: Blanch the beans for 4 minutes to soften them slightly without overcooking; they’ll finish cooking in the oven. Overblanching turns them mushy and grayish.
Substitutions: Use 50g oatmeal crushed instead of crackers for a gluten-free crunch. Replace cream with 40g Greek yogurt for a tangier, lighter sauce.
Common mistakes: If the sauce splits or looks oily after baking, you added the cream too hot. It should simmer gently until thickened, not boil.
Storing and reheating: Eat within 2 days; reheat covered in the microwave for 1 minute, stirring halfway. Freezing isn’t recommended. The onions lose crispness.
Serve with: Pair with roasted chicken thighs for a holiday dinner, or serve alongside grilled fish for a lighter vegetarian meal.
