PSA: Mashed potato lovers, I have news for you! Serve an elegant twist on your everyday mash with Parmesan mashed potatoes. Just as heavenly fluffy and comforting and easy to make, but with a cupful of grated hard cheese to give it some edge. Dress it down with weeknight sausage and baked beans or up with Italian-inspired casseroles. This simple side just got sexy.
Do you serve roast potatoes or mashed potatoes with your Sunday lunch? If you don’t want to tamper with an old favourite, here’s a traditional recipe for you with optional green onions.

Parmesan mashed potatoes
Simple dishes that contain few ingredients rely on the quality, or suitability, of those ingredients. This cheesy mash recipe requires the right kind of potato and a decent hard Italian cheese.
Potatoes come in thousands of varieties but can be split into two groups: waxy or floury (starchy). For the desired fluff factor in mashed potato, we need the starchy kind, which have a lower water content.
Starchy potatoes are excellent mashers, roasters, boilers and bakers. They cook into that dreamy feathery texture that is so irresistible.
Waxy, on the other hand, stay firm when cooked and hold their shape. These are preferred for potato salad or cooking in chunky soups or stews. NB for blended soups, go for floury.
In North America, Russet or Idaho potatoes are the most popular starchy ones, while in the UK we favour Maris Piper or King Edward.
And cheese. If you’re no stranger to my blog, you will know what I’m going to say! Grate your own Parmesan from a block, do not use the pre-grated kind.
If you’re new, I’ll tell you why, the rest of you can join in because you know the words! Freshly grated This is an affiliate link.Parmesan cheese is infinitely more flavoursome, and it does not contain anti-caking agents which hinder its meltability and alter its texture (it’s like eating sand).
A block of Parmesan will be more expensive than its pre-grated counterpart, but it will last well and has so many uses. You’ll wonder how you ever cooked without it! Parmesan is the most expensive of the Italian hard cheeses, so if you’re on a tight budget, Grana Padano or Pecorino Romana are solid alternatives.

Recipe Tips and Notes
- Use the right kind of potato! It seems obvious, but don’t think you can get away with a waxy spud for a light and frothy mash. Starchy potatoes for mash. Waxy for potato salad. It’s kitchen law.
- After draining, leave the potatoes to steam dry in the This is an affiliate link.colander for a few minutes. Give them a quick shake to shuffle them about, then leave to steam dry again. The less liquid, the more fluff.
- I’m old school and use a This is an affiliate link.potato masher. You can control how chunky or smooth you want it, and the result is a textured mash.
- Or you could use a This is an affiliate link.ricer. It’s similar to a garlic press, if you’re not familiar. After ricing the potatoes, add the other ingredients and stir until super smooth.
- I have known people to use a This is an affiliate link.food processor to ‘whip’ potatoes, but I don’t like it myself! I find the mash comes out too pasty.
- My cheesy mashed potato recipe is just potato, milk, butter and Parmesan cheese. There is beauty in the simplicity!
- Personally, I don’t think this recipe needs garlic. But if you must, you must. Just use roasted garlic. Roasted garlic is more of a mellow flavour that won’t override the Parmesan.
- Please please please do not use pre-grated Parmesan cheese here. Or ever. Ever! Those dusty shavings are packed with starch meaning they don’t melt well and your lovely mash will be disappointingly grainy.
- Invest in a decent block of hard cheese: Parmigiano Reggiano, Pecorino Romano or Grana Padano. While pricier than the pre-grated Parma dust, they are far more potent, and they will last well. It is so worth it!

Serving suggestions
Mashed potatoes go best with saucy meals. Imagine a pile of steaming textured mash absorbing a warm puddle of gravy! My heaven. Here are some of my favourite dishes for a heady Parmesan mash side, in particular:
- Salisbury steak with onion and mushroom gravy– a retro dish of beefy patties, oozing with earthy gravy.
- Chicken and leek pie – cheesy mashed potatoes love leeks, this tangy Parmesan version instantly elevates the humble pie.
- Tuscan butter beans with spinach and sun dried tomatoes – with one foot firmly planted in Italy already, Parmesan mash is right at home soaking up the luscious creamy sauce.
- Spanish chicken in bravas sauce – this sauce is insanely good! Although it traditionally comes with roast or sautéed potatoes, you will not want to waste one single drop, and mash will oblige in soaking up every millilitre!
- All the stews! Mash and stew were made for each other. Thanks to the heavy hints of hard cheese, slow cooker Italian beef stew would be my first choice.
Storage and leftovers
Besides being refrigerated (3-4 days), leftover cheesy mashed potatoes can be conveniently repurposed for another meal. If you have enough, use it as a ready-made topping for mashed potato casserole or easy fish pie.
