- Heat half of the oil in a large frying pan over high heat. Cook rissoles for 2-3 minutes. Turn and cook for a further 1-2 minutes or until golden. Transfer to a plate.
- Heat the remaining oil and the butter in the same pan over medium heat. Add brown onion. Cook, stirring, for 10-15 minutes or until caramelised. Add remaining soup mix. Stir in stock and cream. Season with pepper. Bring to a simmer.
- Return rissoles to the pan. Reduce heat to low. Simmer for 10 minutes or until sauce has thickened and rissoles are cooked through.
