Mashed Potatoes and Peas
Minty mashed potatoes and peas is a Spring-inspired side that’s perfect for lamb dishes. Cooked and mashed in one pot in 20 minutes, this minty mash makes a quick and easy side for weeknight dinners or special occasions such as Easter.

Mash is a favorite in our house and as I’m forever trying to sneak in extra veg, this minty mash with peas was born. A perfect side for hearty lamb dishes, this Spring-inspired mash is creamy and rich thanks to a generous knob of butter.
All cooked and mashed in one pot, this potato mint mash is a quick and easy side dish you can make in 20 minutes.
I like serving it with rich lamb dishes such as my slow-cooked lamb shanks in red wine or parmesan-crusted lamb chops.

Ingredients and substitutions

- Potatoes – Yukon Golds or a mix of Yukon Golds and Russet potatoes are best for mash.
- Peas – I use frozen peas for convenience but fresh would be delicious addition as well.
- Mint – Fresh mint lightens up the mash and makes it a perfect side for lamb dishes. Fresh parsley or chives would work well too.
- Milk – I use whole milk but you can choose a lighter option or heavy cream for richer mash as well. Make sure it’s warm so it doesn’t cool down the mash before serving.
- Butter – Salted or unsalted butter can be used. Simply adjust the salt accordingly when seasoning the mash to taste.
- Seasoning – Seasoned with salt and freshly ground black pepper, this pea potato mash creates a not too overpowering side for rich meat dishes. You can add fresh garlic or garlic powder if you’re after a richer version.

Leftover mash ideas
Mashed potatoes and peas are a delicious side for hearty meat dishes but you can use the Spring mash in a variety of ways:
Topping for pies: The minty mash makes an excellent topping for lamb shepherd’s pie and other meaty potato topped pies.
Mash fritters or croquettes: Turn the mash into fired morsels by adding flour, eggs, and extra seasoning, frying them as patties or small croquettes.
