Mushy peas are a classic British side dish, traditionally served alongside fish and chips. This version uses dried green split peas, which break down into a creamy, savory mash with a fraction of the effort of the original marrowfat peas. The result is a comforting, earthy, and surprisingly simple dish that pairs perfectly with fried foods or as a hearty side to roasted meats.
Ingredients
- 1 ½ cups (300 g) dried green split peas, rinsed and picked over
- 4 cups (960 ml) water or vegetable broth
- 1 small onion, finely chopped (about ½ cup / 75 g)
- 1 teaspoon salt, plus more to taste
- ½ teaspoon black pepper
- 2 tablespoons (30 g) butter or olive oil
- 1 tablespoon (15 ml) lemon juice or malt vinegar (optional, for brightness)
Instructions
- Rinse the split peas in a fine-mesh strainer under cold water. Remove any small stones or discolored peas.
- In a large saucepan or Dutch oven, combine the rinsed peas, water or broth, and chopped onion. Bring to a boil over high heat.
- Reduce heat to low, cover, and simmer gently for 45 minutes. Stir occasionally to prevent sticking.
- After 45 minutes, add the salt and pepper. Continue to cook, uncovered, for another 20–30 minutes, stirring frequently, until the peas are very soft and have mostly broken down. The mixture should be thick and porridge-like.
- Remove from heat. Stir in the butter or olive oil and, if using, the lemon juice or vinegar. Mash with a potato masher or puree with an immersion blender for a smoother texture. Taste and adjust seasoning.
- Serve hot. If the peas thicken too much while standing, loosen with a splash of hot water or broth.
Tips
- Don’t add salt too early: Adding salt before the peas are tender can slow softening. Add it after the first 45 minutes of cooking.
- Use a heavy-bottomed pot: Split peas tend to stick and scorch at the bottom. A heavy pot and frequent stirring, especially toward the end, prevent burning.
- Adjust consistency: For looser peas, add more liquid; for thicker, cook longer. Traditional mushy peas are thick but not stiff.
- Substitute broth: Vegetable broth adds depth, but water works fine. If using broth, reduce the added salt accordingly.
Serving Suggestions
Serve mushy peas as a classic side to fish and chips, alongside a meat pie, or with bangers and mash. They also work well as a dip with crusty bread or as a topping for baked potatoes.
Variations
- Minty peas: Stir in 2 tablespoons of chopped fresh mint just before serving for a fresh, bright flavor.
- Smoky peas: Add a pinch of smoked paprika or a few drops of liquid smoke to the pot for a subtle smoky note.
- Vegan version: Use olive oil instead of butter and vegetable broth instead of water.
- Spicy kick: Add a finely chopped chili or a dash of hot sauce to the simmering peas.
Storage and Reheating
Refrigerate leftover mushy peas in an airtight container for up to 4 days. To reheat, place in a saucepan with a splash of water or broth and warm over medium-low heat, stirring frequently until hot. You can also microwave in 30-second bursts, stirring between. The peas will thicken as they sit; add liquid as needed. Freeze for up to 3 months in a freezer-safe container; thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Can I use yellow split peas instead of green? Yes, yellow split peas work just as well and will produce a slightly milder, sweeter flavor and a golden color. The cooking time is similar.
Do I need to soak split peas before cooking? No, split peas do not require soaking. They cook relatively quickly compared to whole dried peas. If you do soak them, reduce the cooking time by about 15 minutes.
Why are my mushy peas still grainy? This can happen if the peas are not cooked long enough or if the heat was too high, causing them to harden. Ensure you simmer gently and cook until they are completely soft. Pureeing with an immersion blender can also help smooth out any remaining texture.
Can I make mushy peas in a pressure cooker? Absolutely. Combine the peas, liquid, and onion in the pressure cooker, cook on high pressure for 15 minutes, then let the pressure release naturally for 10 minutes. Stir in the butter and seasonings after releasing the rest of the pressure.
What is the difference between mushy peas and split pea soup? Mushy peas are much thicker and less liquid than soup. They are meant to be a side dish, not a broth-based soup. The ratio of liquid to peas is lower, and they are cooked down until very thick.
Can I use frozen or canned peas instead? Frozen or canned peas will not give the same creamy, starchy texture as dried split peas. They are better suited for a quick pea puree, but the result will be different—lighter and less hearty.
