Mushy peas are a classic British side dish, most famously served alongside fish and chips. This version skips the mint entirely, letting the sweet, earthy flavor of the marrowfat peas shine through with just a hint of salt, sugar, and a knob of butter. The result is a thick, creamy, and comforting side that comes together in about 30 minutes of hands-on time (plus an overnight soak), and it pairs perfectly with everything from fried fish to a simple roast chicken.
Ingredients
- 2 cups (400 g) dried marrowfat peas (or dried green split peas as a substitute)
- 1 teaspoon baking soda (to help soften the peas)
- 4 cups (950 ml) water, for soaking
- 2 cups (475 ml) water or vegetable stock, for cooking
- 1 tablespoon (15 g) unsalted butter
- 1 teaspoon salt, plus more to taste
- 1/2 teaspoon sugar (optional, to balance flavor)
- Freshly ground black pepper, to taste
Instructions
- Soak the peas overnight: Place the dried marrowfat peas in a large bowl, cover with 4 cups (950 ml) of water, and stir in the baking soda. The baking soda helps soften the pea skins, which is key to achieving that creamy, mushy texture. Cover and let soak at room temperature for at least 8 hours or overnight.
- Drain and rinse: The next day, drain the peas in a colander and rinse them thoroughly under cold running water. This removes the baking soda, which can leave a bitter taste if not washed off.
- Cook the peas: Transfer the soaked peas to a medium saucepan. Add 2 cups (475 ml) of fresh water or vegetable stock. Bring to a boil over medium-high heat, then reduce the heat to low, cover, and simmer gently for 45–60 minutes, stirring occasionally, until the peas are very soft and falling apart. Add more water if the mixture becomes too dry before the peas are fully tender.
- Mash and season: Once the peas are tender, remove the pan from the heat. Add the butter, salt, sugar (if using), and a generous pinch of black pepper. Use a potato masher or a fork to mash the peas to your desired consistency—smooth for a classic chip shop style, or slightly chunky if you prefer more texture.
- Adjust consistency: If the peas seem too thick, stir in a splash of hot water or stock until they reach a spoonable, thick porridge-like consistency. Taste and adjust seasoning with more salt and pepper if needed.
- Serve: Spoon the mushy peas into a bowl and serve hot. They will thicken as they cool, so if you are not serving immediately, keep them warm over low heat and add a little extra liquid before serving.
Tips
- Substitute for marrowfat peas: If you cannot find marrowfat peas, use dried green split peas. They cook faster (about 30–40 minutes) and do not require an overnight soak, but they will have a slightly different, more lentil-like flavor and a slightly less creamy texture.
- Don’t skip the baking soda: The baking soda is essential for breaking down the pea skins, which is what gives mushy peas their signature smoothness. However, be sure to rinse the peas thoroughly after soaking to avoid a soapy taste.
- Make it vegan: Simply replace the butter with a plant-based butter or a tablespoon of olive oil. The rest of the recipe is already vegan.
- Common mistake: Adding salt during the soaking or early cooking stage can toughen the pea skins. Always add salt at the end, after the peas are already soft.
Serving Suggestions
Mushy peas are the quintessential accompaniment to fish and chips—serve them alongside battered fried fish and thick-cut chips for a proper British takeaway. They also work well as a side to bangers and mash, grilled sausages, or a Sunday roast. For a lighter meal, try them with a poached egg on toast or as a bed for sautéed greens.
Variations
- Classic with mint: If you change your mind, stir in 2 tablespoons of finely chopped fresh mint just before serving for the traditional British version.
- Pea and ham: Add 1/2 cup (75 g) of diced cooked ham during the last 10 minutes of cooking for a heartier, smoky flavor.
- Spiced mushy peas: For a twist, add 1/2 teaspoon of ground cumin and a pinch of chili flakes along with the butter for a subtle warmth.
- Extra creamy: Stir in 2 tablespoons of heavy cream or crème fraîche after mashing for an indulgent, velvety texture.
Storage and Reheating
Store leftover mushy peas in an airtight container in the refrigerator for up to 3 days. They will thicken considerably when chilled. To reheat, place them in a saucepan over medium-low heat with a splash of water or stock, stirring frequently until hot and creamy. You can also reheat them in the microwave in 30-second bursts, stirring in between. Avoid freezing, as the texture can become grainy and watery upon thawing.
Frequently Asked Questions
Can I use frozen peas instead of dried marrowfat peas?
Yes, but the texture will be different. Frozen peas cook in about 5–7 minutes and do not need soaking. Simply simmer them in a little water until tender, then mash with butter and seasoning. The result will be brighter green and slightly less starchy, but still delicious.
Why are my mushy peas watery?
This usually happens if you add too much cooking liquid or mash them too early. Let the peas cook until they are very soft and most of the liquid has been absorbed. If they are still watery, simmer uncovered for a few extra minutes to evaporate excess moisture.
Can I make mushy peas in a pressure cooker or Instant Pot?
Yes. After soaking, pressure cook the peas with 2 cups (475 ml) of water or stock on high for 15 minutes, then let the pressure release naturally for 10 minutes. Mash and season as directed. This cuts the cooking time significantly.
Do I really need to soak the peas overnight?
Yes, for dried marrowfat peas, an overnight soak is essential to rehydrate them and soften the skins. Without soaking, they will take much longer to cook and may remain hard in the center. If you are in a hurry, you can do a “quick soak�: cover with boiling water and let sit for 1 hour, but the texture will be slightly less creamy.
Can I serve mushy peas cold?
Technically yes, but they are traditionally served hot. Cold mushy peas will be very thick and pasty. If you want a cold pea side, consider making a fresh pea salad instead.
What is the difference between mushy peas and pease pudding?
Pease pudding is a thicker, more solid dish made from split peas, often boiled in a cloth bag and served sliced. Mushy peas are looser and more porridge-like. Both are British, but they are prepared and served differently.
