Whether it’s a quick lunch at home or a BBQ with friends, these brioche buns make every bite feel more indulgent without adding extra effort.
The lightly sweet taste of brioche pairs perfectly with savoury fillings, while the caramelised onion adds a subtle twist that helps elevate everyday meals. Warm them lightly before serving to bring out their soft texture and golden finish.
