Place a frying pan over medium heat. Add butter and chopped onions. Cook gently for 5–7 minutes until soft and slightly golden. Stir often so they do not burn.

Put fresh breadcrumbs into a large mixing bowl. If you don’t have fresh breadcrumbs, you can make them using slightly stale bread.

Add cooked onions into the breadcrumbs. Then add chopped sage, salt, and black pepper. Mix everything well so the flavor spreads evenly.

Pour the beaten egg into the mixture. Stir gently until everything starts to come together. The mixture should feel slightly moist and soft.

Slowly pour vegetable stock into the bowl. Mix again until the stuffing is moist but not too wet. It should hold its shape when pressed.

You can shape the stuffing into small balls or press it into a baking dish. Both methods work well depending on your preference.

Set your oven to 180°C (350°F). Allow it to heat while you prepare the stuffing for baking.

Place the stuffing in the oven. Bake for 25–30 minutes until the top is golden and slightly crispy.

Remove the stuffing from the oven. Let it rest for a few minutes before serving. This helps it set and improves texture.

Serve warm with roast chicken, turkey or vegetables. Now you know how to make Mary Berry's Sage and Onion Stuffing at home.
