Mashed Potatoes and Parsnips

This creamy potato and parsnip mash offers a sophisticated twist on a classic British side dish. By blending earthy parsnips with fluffy potatoes, you create a mash that is naturally sweeter and more fragrant than the traditional version. The addition of fresh parsley and a subtle hint of cayenne pepper provides a gentle warmth, making it a versatile accompaniment to Sunday roasts, vegetarian sausages, or a rich mushroom ragout.

A nutritious and comforting vegetarian option, this recipe is an excellent way to introduce more root vegetables into your weekly meals. The parsnips add a silky texture and a boost of fibre, while the simple mashing technique ensures a consistent, lump-free finish. Prepare this dish for a family dinner or a festive gathering for a wholesome, homemade touch that everyone will enjoy.

Ingredients for Mashed Potatoes and Parsnips

  • 8 medium red or white new potatoes, washed and cubed.

  • 4 parsnips, peeled and cubed

  • 240ml milk

  • 3 tablespoons butter

  • 1 tablespoon chopped parsley

  • Dash cayenne pepper

  • Several grindings of black pepper

  • 1 teaspoon salt

Put the potatoes and parsnips in a large pot with water, making sure that the water completely covers them. Bring to a boil, lower the heat to medium, then cover and simmer for 20-30 minutes, stirring occasionally with a spoon. Test the tenderness of the potatoes with a fork; they should pierce easily and be tender, yet firm. Drain any remaining liquid and mash the potatoes with a potato masher until there are no visible lumps. Add the milk and butter and continue to mash until the potatoes are smooth and creamy. Stir in the parsley, cayenne pepper, black pepper, and salt, and beat thoroughly with a wooden spoon until all the seasonings are completely mixed in. Cover and serve warm.
