The BEST Roasted Sweet Potatoes!

I’ve been wanting to upload a roasted sweet potato recipe for a while, but have waited until I could offer something insanely delicious. I mean we’ve all roasted sweet potatoes right? Well, these are next level. IF I do say so myself 🤣 Here’s why I think you’ll love them:

  • Rosemary & Garlic – Name a more iconic duo.
  • EXTRA Crispy – Alongside the crispy rosemary stems and crispy chorizo crumbs, I’ll show you a few tips to getting crispy roasted sweet potatoes!
  • Balance of Flavours – The chorizo offers a salty and spicy aspect which plays off nicely with the sweetness of the potatoes.

These are the perfect side dish for just about anything. But realistically I could sit and eat them straight from the bowl.

Exhibit A:

Honestly? These potatoes are gorgeous with just the garlic and rosemary, so if you’re vegan/vegetarian you’re in luck! The chorizo just takes things to new heights. In both circumstances  though what we DO want is a crispy potato. I have an in depth post on getting Crispy Sweet Potato Fries, but sweet potato chunks are a little more difficult to get crispy. Here’s a few tips to help you along the way though:

Tips for Crispy Roasted Sweet Potatoes

  • Use a lot of oil – I actually use 2.5 tbsp for 2lb/1kg. Don’t skimp on this or they’ll come out soft and chewy.
  • Space them out – Don’t pile them on top of each other or they’ll steam instead of roast.
  • Perfect temp – 200c/390f is the sweet spot. Too high and they’ll char before they cook through, too low and they’ll slowly turn to mush.
Bonus Tip! Soak your potato chunks in cold water for 30mins to remove starch. Starch is what makes the potatoes go gloopy in the centre, so removing some of this will help for extra crispiness. Just make sure you thoroughly dry them after to remove all moisture.

How to make the best Roasted Sweet Potatoes (quick summary)

  1. Dice sweet potato into 1″ chunks.
  2. Combine with fresh rosemary, whole garlic cloves, olive oil and seasoning.
  3. Roast and flip.
  4. Sprinkle Chorizo then quick roast.

Chorizo Roasted Sweet Potatoes

Here’s where things get intense. That crispy, smoky chorizo oozing out it’s gorgeous oil into the sweet potato? Yes please.

I use regular cured Spanish Chorizo and grate it on a box grater to get the fine chorizo crumbs. From there you really only need to roast the potatoes again for a matter of minutes, just to crisp up the chorizo and extract some oil too. 

You could also finely dice the chorizo to mimic the crumbs, totally up to you. You may just need to roast for a few more mins at the end to get it nice and crispy.

Should I peel the Sweet Potatoes? 

I tend to for this recipe, but honestly it doesn’t make a huge difference. The skin doesn’t get hugely crispy, but does add some nice flavour.

Can I use Dried Rosemary?

I don’t recommend dried herbs for this recipe. The fresh rosemary infuses the oil and potatoes far better. It also leaves you with crispy rosemary stems, which are too good to miss out on!

Can I use bacon or pancetta instead of chorizo?

Chorizo has a stack more flavour, it also adds a gentle spice which works nicely with the sweetness of the potatoes. However, if you don’t have or like chorizo, bacon/pancetta will add a nice salty aspect to the dish. Just obviously roast it longer with the spuds to get crispy.

  • 28cm x 40cm (11” x 16”) Oven Tray (or similar size)
  • Spatula/Turner
  • Sharp Knife & Chopping Board
  • Box Grater (for chorizo)

Ingredients (check list):

  • 2lb / 1kg Sweet Potatoes, peeled and diced into 1" chunks
  • 2.6oz / 75g Chorizo (see notes)
  • 2.5 tbsp Olive Oil
  • 1 bulb of Garlic, cloves slightly crushed with palm of hand, skins left on
  • few sprigs of Rosemary
  • Salt & Pepper, to taste


  • Combine 2lb/1kg sweet potato chunks with 2.5tbsp olive oil, a small bulb of garlic cloves, a few sprigs of fresh rosemary and a good pinch of salt and pepper.
  • Space out as much as you can, then pop in the oven at 200c/390f for 30-40mins or until fork tender and nicely caramelized on the outside. Flip the potatoes 1-2 times throughout and turn oven tray around if cooking unevenly.
  • Sprinkle 2.6oz/75g chorizo crumbs over the top and pop back in the oven for a few mins (careful, the chorizo chars quickly, this is just to crisp it up slightly and extract some of that gorgeous oil).
  • Remove garlic and large woody stalks of rosemary (keep crispy stems if not completely charred). Serve up right away with an extra pinch of salt (optional).

Quick 1 min demo!


a) Chorizo - I usually get regular cured Spanish chorizo and grate it on a box grater to make the crumbs. You can finely dice, just depending on how big the crumbs end up you may need to bake longer.
b) Spacing - Important to space the potato out otherwise it'll steam instead of roast. If you only have smaller trays, I recommend using two.
c) Timing - Sweet potatoes tend to char quite quickly, so just be vigilant after you flip them the first time. I don't recommend whacking up the temp, neither the sweet potato or olive oil will take the heat. The chorizo should take no longer than 5mins before it starts to char, so again just be vigilant.
d) Extra Crispy - Sweet potatoes are difficult to get truly crispy in the oven, because they're packed with so much water/starch. If you've got the time, soak your potato chunks in cold water for 30mins, then THOROUGHLY dry. This will extract some starch and make them less gloopy in the centre. Not a huge difference, and they do still come out fairly crispy without doing this, but just a little tip for you!
