Why this recipe works
Mushy Peas…. If you’re anything like me, you absolutely love them!!! Often they are packed full of rubbish when there really is no need for it! My healthy mushy peas have just 4 natural ingredients meaning they have no nasties AND they are incredibly simple to make, so give them a try!
Mashed peas are a common find in a British fish and chip shop, and they are so easy to make at home! Serve them with your Sunday dinner, fish, chicken, salmon, sausages or mash. Leftovers are lovely the next day on toast, on a jacket potato or stirred through pasta.
If you are looking for a great new mashed peas recipe or just wondering how to make mushy peas, look no further! This recipe is so incredibly simple, but stands up against any other recipe I’ve tried!
While these peas are great all year round, they really come into their own in autumn and winter next to a pie or a roast. Try them with my Chicken and Leek Pie.
This was inspired by my Refreshing Pea & Avocado Dip and pairs well with this amazing Air Fryer Salmon.
Ingredients to make Mashed Peas

- Frozen Peas: are just as good as fresh peas, but you don’t have to shell them and they keep for months! You need 300g for 3 portions. If you have some spare then try my Pea and Mint Soup.
- Olive Oil: adds a fruity flavour and makes the peas creamy without any cream.
- Fresh Basil: has both a sweet and savoury taste to it.
- Salt and Pepper: finish up this delicious side by really bringing out the flavours.

Substitutions
- Frozen Peas: This combination of flavours also works well with tinned marrowfat peas, or dried marrowfat peas soaked overnight and simmered until soft.
- Olive Oil: Other oils will work, but be wary of what flavour they bring to the peas. You could opt for butter as another option.
- Fresh Basil: If you don’t have fresh basil, you could use dried basil. You could also use mint and lemon to flavour these peas.
Variations
- Spicy: Mashed peas are not typically a spicy dish, but you could add a pinch of chilli flakes for some heat.
- Deluxe: Top with a piece of fresh basil or serve with my Air Fryer Broccoli.
- Kid friendly: Blend them smooth and serve alongside something they love, like fish fingers or sausages, so they are more willing to try something new!

How to make Mashed Peas

Step 1: Boil the frozen peas for 2 to 3 minutes, until bright green and just tender.

Step 2: Drain them, keeping back a splash of the cooking water, and add to a small food processor (or back to the pot) with the olive oil, fresh basil, salt and pepper.

Step 3: Blend (or blend with a hand blender) to the consistency you want and they’re ready to serve.
Hint: Blend for longer for a smooth, creamy mash, adding a splash of the cooking water if needed, or pulse briefly for a chunkier, chip shop style. I like them chunky next to my Salmon Fishcakes.
Leftovers
Mashed peas are great for batch cooking and lovely hot or cold! Keep them in an airtight container in the fridge for up to 2 days, or in the freezer for up to 3 months. Reheat in a pan over a low heat or in the microwave until steaming hot. They are delicious spooned onto my Air Fryer Jacket Potato.
Recipe FAQs

Blend the peas with a little olive oil and a splash of the cooking water. Keep going until they are as smooth as you like. A small knob of butter works too if you have it.
Peas are a good source of fibre and plant protein. This version uses 1 tbsp of olive oil for 3 portions and no cream, so it is about 118 kcal and 5g of fibre a portion.
Chip shop mushy peas are made from dried marrowfat peas, soaked overnight and simmered until they break down. Mashed peas use garden peas, so they are greener, fresher tasting and much quicker.
The most common way is as a side, especially for fish. They are also great on toast, on a jacket potato, stirred through pasta, with sausages, or next to a pie like my Lentil Cottage Pie.
Yes. Leave out the salt (babies should not have added salt), blend them smooth and let them cool before serving. They are easy to eat and full of fibre.
