Crispy potato fries covered in truffle oil and Parmesan are the ultimate, flavour packed side dish. These Parmesan Truffle Fries are an easy way to up your fries game, and are delicious with burgers, pizza, chicken, and just about anything else. These are our go-to side dish when we eat out, so I wanted to create them at home myself, and make them a little lighter with less oil.

The first time we tried Parmesan truffle fries in a restaurant, we were hooked. The flavour is just so incredibly indulgent. But, they were fried and left us feeling stuffed. So, we have made our own baked version, that still have all the delicious flavour.
Healthier alternatives to our favourite restaurant/takeaway foods was how this website started, and we are going to bringing a bit more of that back again.
If you haven't tried truffles before, then this is an easy way to give the flavour a try, as these fries are made with truffle oil which you can just pick up at the supermarket. These are like next level homemade oven chips.
If you want more flavoured fries, take a look at our spicy Salt and Pepper Chips, Nando's copycat Peri Peri Fries or our delicious, Indian inspired Masala Chips.

Ingredients and Substitutions
A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Potatoes - Any potatoes will work, but some definitely work better than others. We try to use a floury potato like a King Edward, Maris Piper or Russet potatoes, as they have produced the best results for us.
- Oil - Try to use a natural truffle oil, rather than a synthetic one as you will really be able to taste the difference.
- Thyme - You could use oregano or rosemary instead if you prefer. Fresh parsley is also good.
- Garlic - We used garlic powder for this recipe, as we find that fresh garlic can burn a bit too easily.
- Parmesan - It isn't Parmesan fries without Parmesan cheese. If you want to keep these fries vegetarian, then you can use a vegetarian hard cheese alternative.
More ingredient substitutions and variations can be found in the recipe card.
How To Make Parmesan Truffle Fries
Prep: Preheat your oven to 200°C/180°C/400°F/Gas 6.
- Step 1: Add the fries to a pan of boiling water and simmer for 5 minutes. Drain them and allow them to steam in colander for 5 minutes.
- Step 2: Add the fries to a large bowl with the olive oil, garlic and thyme and mix well.
- Step 3: Put them on a baking sheet, well spaced apart, and cook in the oven for 15 minutes.
- Step 4: Transfer them to a bowl and toss with the Parmesan and truffle oil.
- Step 5: Put them back on the baking tray and back in the oven for a further 10 minutes until golden brown and crispy.
Air Fryer Parmesan Truffle Fries
To make these even lighter, but using less oil, you can make them in the air fryer. Follow the same par-boiling and drying steps, then air fry in batches with a little spray oil, so the fries are not crowded.
Add the Parmesan and truffle oil near the end and cook just long enough for the cheese to melt onto the fries.
Serving Suggestions
These Parmesan truffle fries work brilliantly with air fryer burgers, slow cooker chicken breasts or an epic pesto chicken sandwiches.
For dipping sauces, garlic mayo, truffle mayo, aioli, sour cream dip or even a simple lemony yoghurt dip all work well. If you are serving them as party food, pile them onto a platter with a little extra Parmesan over the top and plenty of napkins nearby.
They also make a good sharing side for date-night dinners or homemade steak nights (try our air fryer steak).
Meal Prep and Storage
Meal prep - You can cut the potatoes ahead of time and keep them in a bowl of cold water in the refrigerator for up to 24 hours. Drain and dry them well before par-boiling.
You can also par-boil the fries earlier in the day, drain them, and let them cool completely. Keep them covered in the fridge, then toss with the oil, garlic and thyme just before baking.
Leftovers - Leftover fries can be stored in an airtight container in the fridge for up to 2 days. They will soften as they sit, but you can reheat them in a hot oven or air fryer until crisp again. Avoid reheating in the microwave if possible, as they tend to go soft.
These are best eaten fresh, but if you do need to reheat them, spread them out on a tray and bake at 200°C/400°F for about 8 to 10 minutes, or until hot and crisp.
Dannii's Top Tips
- Make sure to cut all your fries to an even size, as this will ensure that they all cook evenly and all get nice and crispy.
- You want to make sure that all your fries have enough space on the baking tray to all get crispy. If they are too close together, then they will steam, rather than bake and they will stay soggy. Use two baking trays if needed.
- Grate the Parmesan finely so it clings to the fries more evenly. A very coarse grate is more likely to fall off.
- You can also make these into potato wedges. However cooking times will vary as they are thicker.
Frequently Asked Questions
No, you don't have to, however we find they they cook quicker in the oven. Add about 10 minutes on to cooking time if you don't par-boil them.
To make these vegetarian, then use a vegetarian hard cheese alternative. To make them vegan, then you can just leave the Parmesan about completely. All the flavour is from the truffle oil anyway, but you might want to add a little extra salt.
These are best made and eaten fresh. However, if you do have any leftover then you can store them in an air tight container and store them in the fridge until the next day. Then put them baking on a baking tray and heat through in the oven.
Yes, you can definitely use frozen fries to make these. Simply skip the par-boil stage and then follow the rest of the instructions. They probably won't need as long in the oven.
