Roast Potatoes with Sage and Garlic

Today I’m jumping back into the world of potatoes with a recipe for Roast Potatoes with Sage and Garlic. I mentioned how much I love potatoes in my Duck Fat Hasselback Potatoes post but this recipe is a much simpler alternative. While the Hasselback potatoes with blue cheese are a bit fancy, these roast potatoes are more traditional and partner with almost anything. Well not anything, but most things that you’d eat potatoes with, put it that way!

There’s not a lot of roast potato recipes that cook the potato whole and that’s what sets this method apart. It gives amazing results, with soft fluffy potatoes that are crispy and crunchy on the outside. They’re so easy to put together and there’s a lot of scope for flavour variations. When picking the right potatoes for this recipe, aim to get ones that are on the larger side. If they’re too small they won’t work as well in the flattening process. I usually find that the potatoes are filling enough that one per person is plenty, so use that as a guide if scaling the recipe.

Roast Potatoes with Sage and Garlic

Sage and garlic, optional

Sage and garlic is a great combination to go with roast chicken or turkey. It’s the way I’ll usually cook this recipe and that’s why I’ve used it here. I’ll often cook these to go with Christmas lunch. If you want to serve them with red meat, consider swapping the sage for rosemary or thyme. You could also place them alongside fish with some dill.

It really comes down to pairing up the herbs with whatever you’re serving it with. If you’re using rosemary with your lamb, it will help tie everything together using rosemary with the potatoes. Experiment a little and see what combination works for you.

It’s also possible to swap out the fat. I’m using butter because it adds a great flavour and it gives the best golden colour. You can easily swap it out for olive oil or animal fat. I’ve made these several times using duck fat and it’s a good combination. It’s just a bit harder to get a rich gold crust, so you may need to increase the cooking time by about 30 minutes or increase the oven temperature to compensate.

I’ll sometimes cheat a little and add a dash of olive oil on top of my duck fat potatoes towards the end of the cooking time to give them a little helping hand. There’s no harm in leaving the potatoes in the oven for longer to achieve the crispy shell, as you can’t really overcook them.

Fluffy roast potatoes

To make these roast potatoes, start by peeling and parboiling them in salted boiling water for about 15 minutes. It’s important to cook the potatoes well at this point. As they are whole, they need more cooking time than you would for diced potatoes. It’s also crucial to soften them so that they can be chuffed up in the next step. A good guide is to test with a knife while boiling – if you can easily insert it without too much resistance, they’re ready.

The trick to making these potatoes soft and fluffy on the inside is by drying them out before roasting. After parboiling, let the potatoes stand in a colander for a couple of minutes. This will steam them and help to dry out their centres. It’s a crucial step, so don’t skip it! The other trick at this stage is to shake the colander a couple of times to rough up the outsides of the potatoes. The little bits of potato that seperate are what gives the fat something to attach to and creates the crispy, crunchy outsides.

Transfer the potatoes to a large roasting pan. The size of the pan should be such that when the potatoes are squashed later on they will snugly fill the gaps. If you pack them too tightly at this stage you won’t have enough room later on. Top each potato with a knob of butter – about half to three-quarters of a teaspoon is a good amount. It will quickly melt and run all over the place but that’s fine. Crush the unpeeled garlic cloves and dot them around the potatoes. Season generously with salt and pepper and give everything a toss to coat evenly.

Roast the potatoes for about an hour. By the end of this first roast the potatoes should be an enticing golden colour. At this point you could quite happily eat these potatoes but we’re about to take them to the next level.

Now for a little trick I learnt from Jamie Oliver. Using a potato masher, gently press down on each potato. The outsides will split and the potato will fluff out a little – this is the aim. Doing this creates more surface area to crisp up and makes a potato-cake-like shape that is even thickness. This is great because it means when it comes to eating, every mouthful will be a little crispy and a little fluffy. It’s far superior to having a huge amount of steaming hot potato to work through in the centre of a whole potato.

Now it’s time to add the sage. As sage leaves are quite thin, it’s good to coat the leaves in olive oil before roasting. I just use a small bowl and soak the leaves for a minute before spreading them over the roast potatoes. By taking this step the sage leaves will crisp up rather than drying out. In essence they become like little sage chips that are tasty in their own right. If you opt to use a different herb, you won’t necessarily need this step. Rosemary will cook just fine without the oil, but you can’t go wrong if you use it anyway.

Crispy, golden roast potatoes

Return the roasting pan to the oven and cook for a further 25 minutes. The potatoes are ready when they’ve turned a rich golden colour all over. The skins should also be a crispy texture if you run a knife over the surface. Serve the potatoes straight from the pan or transfer them to a serving platter. I find they look so enticing in the pan that I like to keep them together for maximum visual impact on the dinner table.

Roast Potatoes with Sage and Garlic

Are you hungry yet? Trust me, these potatoes taste as amazing as they look! I’ve never had anyone complain about these roast potatoes with sage and garlic. They are a tasty side dish that goes with so many things. They also make great leftovers and can be easily reheated in the oven. If you reheat them in the oven they’ll maintain their crispiness but you can also use a microwave if you’re short on time.

If you want to take the stress out of a dinner party, there’s also a handy shortcut to prep this recipe in advance. Simply parboil the potatoes and arrange them in the tray with the garlic and butter. Cover them and leave in a cool, dry place – but not in the refrigerator. When it comes time to cook, preheat the oven and resume the recipe as normal. This little trick can free up precious cooking space on the stovetop when trying to make a lot of seperate dishes.

And that’s all there is to it. Give this one a try and let me know what you think in the comments. I’m sure you’ll enjoy them as much as I do.

    Tossing sage leaves in olive oil is such a good tip! I’ve always disappointed when sage leaves burned out after roasting but not anymore. Thanks James 🙂

    1. Thanks, Kiki! I think crispy sage leaves are the best. Glad the tip helped you out.
