Why this recipe works

Traditional mushy peas can be heavy on additives. This mashed peas recipe keeps things simple with just a few wholesome ingredients, delivering bright flavour and a smooth texture without unnecessary extras. Using frozen peas saves time and reduces waste while still offering excellent taste and nutrition.

Serve these peas alongside fish and chips, roasted meats, salmon, mashed potatoes or a crisp salad. They also work well cold in sandwiches or warmed up the next day. Their vivid green colour makes them a fun addition to seasonal meals, including St. Patrick’s Day menus.

The recipe is inspired by other pea-based dishes and pairs nicely with many mains. It’s an approachable, reliable side that’s easy to scale for family dinners or batch cooking.
