Crispy Lemon Thyme Roasted Potatoes
These roasted lemon potatoes are what happens when a Brisbane Easter long weekend calls for something bright and celebratory rather than heavy. Baby potatoes roasted in olive oil and salted butter with lemon, thyme, and garlic until golden, crispy, and deeply fragrant. Sunshine on a plate, and absolutely no apology for the butter.
Crispy Lemon Thyme Roasted Potatoes
These crispy lemon thyme roasted potatoes are the side dish that earns its place at every table. Golden and crunchy on the outside, fluffy on the inside, and infused with bright lemon and fragrant thyme that makes the whole kitchen smell incredible while they roast. They go with absolutely everything from a Sunday roast to a simple weeknight dinner and they always get demolished first. Save this recipe because once you make them this way you will never want to roast potatoes any other way again!
Ingredients
- 800g baby potatoes, halved
- 3 tbsp olive oil
- 1 tbsp butter
- 1 lemon, zested and juiced (about 3 tbsp juice)
- 4 sprigs fresh thyme, leaves stripped
- 1 tsp sea salt flakes
- 4 garlic cloves, smashed with skin on
Instructions
- Preheat oven to 220°C (fan) or 240°C (conventional). Place a roasting tray in the oven while it heats. This is non-negotiable for crispy bottoms.
- Put the halved potatoes in a large pot, cover with cold salted water, bring to the boil and cook for 12-15 minutes, or until a knife goes in easily but they're not falling apart.
- Drain well, then return them to the hot pot and shake vigorously for 30 seconds. This roughens the surface and creates more crunchy edges.
- Toss the roughed-up potatoes with 2 tablespoons of olive oil, the garlic, thyme, and salt.
- Carefully pull the hot tray from the oven and add the remaining tablespoon of oil and the butter. It should sizzle immediately. Add in the potatoes cut-side down. Don't crowd them. Use two trays if needed.
- Roast for 25 minutes without touching. Flip, squeeze half the lemon juice over, and roast for another 15 minutes, or until deeply golden.
- Remove from the oven, zest the lemon directly over the potatoes, squeeze over the remaining juice, and serve immediately.
Notes
- The key to guaranteed crispiness with baby potatoes is parboiling until almost tender, roughing up the surface, and using a screaming hot pan with enough fat. This method ticks all those boxes.
- I use this heavy-duty roasting tray for potatoes. It heats evenly and holds the temperature beautifully for maximum crispiness.
- Preheating the tray is essential. When the potatoes hit that hot fat, they start crisping immediately rather than steaming.
- Don't skip the shaking step. It creates a rough, floury surface that crisps up into those craggy, golden edges everyone fights over.
- Baby potatoes work best here because they're the perfect size for roasting. Look for ones that are roughly the same size so they cook evenly.
- Smashing the garlic cloves with the skin on releases their flavour without them burning. The skin protects them from the high heat while they infuse the oil.
- Fresh thyme is non-negotiable. Dried thyme won't give you the same bright, herby flavour.
- Don't crowd the tray. If the potatoes are too close together, they'll steam instead of roast. Use two trays if you need to.
- Resist the urge to move the potatoes around. Let them sit undisturbed for the first 25 minutes so they develop a proper golden crust.
- The lemon juice and zest added at the end brighten everything up and cut through the richness. It's the perfect finishing touch.
- These potatoes are best served immediately while they're still piping hot and crispy. They lose their crunch as they sit.
- Leftovers can be stored in an airtight container in the fridge for up to 2 days. Reheat in a hot oven at 200°C for 10-15 minutes to crisp them up again.
- Not suitable for freezing as the texture will turn mushy after defrosting.

An Easter Weekend in the Kitchen
It’s the Easter long weekend, which means I am in the kitchen, obviously. My first instinct was a traditional roast, because that’s who I am at my core, but it’s 27 degrees and sunny outside and this is Brisbane, not Glasgow, and a heavy roast in this weather felt like a decision I’d regret. So instead I went for something a little different, a little brighter, a little more suited to the kind of warm golden day that makes you want to eat outside if only the humidity would cooperate. These lemon roasted potatoes, all buttery and crispy and fragrant with thyme and garlic, and some halloumi schnitzel alongside. Absolute perfection on the plate.
It’s been a bit of a weird week if I’m honest. I’ve been under the weather for a couple of weeks now, first some inflammation and then a head cold that just sat there being annoying. Then I had an altercation at work with a much younger colleague who decided to have a go at me while I was in the middle of thanking them for their help, which is a very specific kind of audacity that I’m still processing. And then on Thursday night I had a spur of the moment visitor and far too much wine, which led to a Friday hangover that pushed a few of my planned recipes back a little. There are still two days left of this weekend though, and carbs and cheese cure everything. This is a medical fact.
I also had an intense reflexology session this morning, which you can read more about over on my personal blog, and I am feeling considerably more human than I was yesterday. Saturday has been redeemed. The kitchen is calling and these potatoes are the answer.
A Brief History of Me and Potatoes
Here is a fact about my life in the UK that still baffles me slightly: for years, I couldn’t eat British potatoes. UK potatoes, for some reason I have never fully understood, trigger my severe inflammation, and so I went without for a significant portion of my time there, which is a particular kind of deprivation when you live in a country that takes the potato very seriously indeed. Here in Australia though? Completely fine. No inflammation, no issue, just potatoes, glorious potatoes, in all their buttery roasted glory.
I buy the low-carb baby potatoes from Coles, which makes me feel marginally less guilty when I devour an entire tray of them in one sitting, which happens more than I’d like to admit. They’re the reason you’ll find not only these lemon roasted potatoes on the blog but also my crispy smashed potatoes, because once you can eat potatoes again without consequences you make up for lost time aggressively. I have no regrets about this approach.
As much as I loved Adelaide, and I would move back in a heartbeat if life pointed me that direction again, my kitchen there was tiny, and real cooking in a tiny kitchen becomes a chore rather than a pleasure after a while. Cooking should never be a chore. Here in Brisbane I have a kitchen that actually begs to be cooked in, bench space and light and room to move, and these lemon potatoes are very much a product of that space. There are absolutely more potato recipes coming. This is both a promise and a threat.
Why This Recipe Works So Well
The combination of olive oil and salted butter is the foundation of everything here. Olive oil gives you the high heat performance you need to get the potatoes properly golden and crispy at the edges, and the butter adds a richness and depth that olive oil alone can’t quite replicate. Together they create a glossy, deeply savoury coating that the lemon and thyme cling to beautifully.
The lemon does two things. The zest goes into the roasting pan early and caramelises slightly in the heat, which mellows it and deepens the flavour, while a squeeze of juice goes over everything at the very end to bring back that bright, fresh acidity. It’s that combination of roasted lemon warmth and fresh lemon brightness that makes these potatoes taste like something more considered than the method would suggest.
The garlic roasts in whole cloves alongside the potatoes, which means by the time everything is done the garlic is soft and sweet and mellow rather than sharp, and you can squish the cloves out and mix them through the potatoes at the end if you want an extra layer of flavour. The thyme runs through the whole thing and ties it all together. Simple, honest, deeply good. Exactly the kind of recipe a Brisbane Easter weekend deserves.
Ingredient breakdown
Baby potatoes
Small, waxy baby potatoes are the right choice here because they have a naturally creamy interior and a thin skin that crisps up beautifully in a hot oven. Halving them gives you a flat cut surface that sits directly on the hot fat in the tray, which is where that deeply golden, crispy base comes from. Look for ones that are roughly the same size so they parboil and roast evenly. No need to peel them.
Olive oil
Used in two stages. The first portion goes on the parboiled potatoes before they hit the tray, coating them along with the garlic, thyme, salt, and pepper. The second goes directly onto the preheated tray with the butter, where it should sizzle immediately when it hits the hot metal. That instant sizzle is what starts the crisping process before the potatoes even go in. Use a decent quality olive oil but save your best extra virgin for finishing rather than roasting.
Butter
A tablespoon of butter goes onto the hot tray with the olive oil just before the potatoes go in. Butter alone would burn at this temperature, but combined with the olive oil it adds a richness and a slightly nutty depth to the crust that oil alone can’t replicate. It’s a small amount that does a disproportionate amount of flavour work.
Lemon
Both the juice and the zest, used at different points and doing different jobs. Half the juice goes over the potatoes at the flip point, halfway through roasting, where it mingles with the hot fat and caramelises slightly around the edges of the potato. The remaining juice and all of the zest go on right at the very end, off the heat, which preserves that fresh, bright citrus flavour and stops it from becoming muted. That combination of roasted lemon warmth and fresh lemon brightness is what makes these potatoes taste like more than just very good roast potatoes.
Fresh thyme
Leaves stripped from the sprigs and tossed through with the potatoes before roasting. Fresh thyme perfumes everything around it as it roasts and adds a herbal, slightly floral note that works beautifully with the lemon and garlic. Dried thyme is not a substitute here. It has a dusty, muted flavour that won’t give you the same result in a recipe where the herb is doing visible flavour work.
Garlic
Whole cloves smashed with the flat of a knife but left with the skin on, which is a deliberate technique. The skin protects the garlic from the intense heat of a 220°C oven and stops it from burning while it slowly infuses the oil and fat around the potatoes with a sweet, mellow garlic flavour. By the time the potatoes are done the cloves inside the skin will be soft and caramelised. Squeeze them out and mix through the potatoes at the end if you want an extra hit of roasted garlic.
Flaky salt and black pepper
Seasoned before roasting rather than at the end, which gives the salt time to draw into the roughed-up surface of the potato and season it properly rather than just sitting on the outside. Flaky salt in particular clings to the craggy, textured surface created by the shaking step and gets crispy in the oven. A good amount of black pepper alongside it adds warmth and a slight bite that suits the lemon and thyme well.
