Garlic Roasted Sweet Potatoes are one of my favourite side dishes. They go with almost everything from fish to pork chops and even make a great addition to salads, tacos and soups. Talk about versatile! As a bonus my recipe includes my top tip for avoiding that burnt horrible garlic taste.
Much as it makes me a huge disappointment to my father, I have to be honest with you about my true feelings. I’m just not a massive fan of regular potatoes. I know, I know, shocker right! But it’s true. Given the choice, I will always choose sweet potatoes over regular.
And so these simple roasted sweet potato cubes are my regular go to side. They really are super versatile and they complement almost all cuisines from Spanish to American BBQ, classic British roasts and even brunch. I will even sometimes us them as an extra topping in Asian inspired dishes.
I prefer to roast my sweet potatoes lower and slower. You can cook them on a higher temperature for a shorter time and this is fine if time is an issue. But I think that the slower cook allows the sweet potatoes to get lovely and soft all the way though and the natural sweetness is enhanced even more.
My Top Tip for Avoiding Burnt Garlic
We’ve all experienced that acrid bitter taste of fresh garlic that has just caught and burnt. As a result, I’m very reluctant to use fresh garlic in dishes like this where tiny pieces of garlic are exposed to high temperatures for a long time.
To get around the issue, I use the chronically underrated Garlic Salt. Found in the spice aisle, garlic salt is exactly what it sounds like. Ground garlic mixed with salt. I’m a big fan and I throw a little on everything, whether thats some char-grilled asparagus or a rib-eye steak.
How to Serve Garlic Roasted Sweet Potatoes
As well as acting as a side almost anywhere where you would use regular potatoes, I also like to make a large bowl of them and eat them dipped in garlic mayonnaise. Nothing else, just a big ass bowl of rosted sweet potatoes and mayo. Lush.
To serve the potatoes as an impressive standalone dish, I like to garnish them with some sour cream, finely chopped spring onion and a little fresh red chilli. Instantly impressive!
Make Garlic Roasted Sweet Potatoes into a Feast
I truly believe that you can make any dish into a proper feast! Whether thats a feast for one after work on a Tuesday, a casual feast for four on a Friday evening or a feast for 12 for a special occasion!
These garlicy potatoes feature in my Vegetarian Americana Feast. They are one of the toppings of my White Bean Chili with loads of other toppings. My Cheesy Garlic Rolls also make an appearance along with Guacamole and chips for with pre-feast drinks.
Don’t forget to head over to the Big Americana Feast post for all of my tips and tricks to help you host a fun and stress-free feast. Plus remember to check out my other feast collections and all my Americana inspired recipes.
I also love to serve these potatoes with my Paprika & Sage Butter Roast Chicken, Maple Roasted Cherry Tomatoes and Topped & Roasted Red Onions which you can see in some of the photos included on this page.
Ingredients for Garlic Roasted Sweet Potatoes
When I talk about sweet potatoes, I’m talking about the dark skinned, orange fleshed, quite sweet kind that we widely get in the UK.
There are numerous other types available around the world including ones with white and purple flesh. I can’t see that this recipe wouldn’t work with other varieties but you may need to keep an eye on the cooking times.
I’ve talked above about how using garlic salt is my top tip to avoiding a burnt garlic taste on the roasted sweet potatoes. If you would rather make your own garlic salt, simply mix 1 part garlic powder with 3 parts fine sea salt.
You can find more of my favourite recipes using garlic in my collection of The Best Garlic Recipes.
There isn’t an awful lot of flexibility to be had with recipes with just four ingredients! What you can do is add extra ingredients like chilli powder or a cumin/coriander mix.
The size of the potatoes can also be varied but do bear in mind that sweet potato shrinks considerably when cooking. Whilst you think you have cut really large sized chunks, you will likely still end with little bite size morsels!
The last way that I vary this method is by making them in the Actifry. You can reduce the amount of olive oil in the recipe and I find that you get a really lovely and even cook on the potatoes. I do tend to take the paddle out of mine halfway through cooking or else they start to break up into tiny pieces!

Equipment Notes for Garlic Roasted Sweet Potatoes
My trusty speed peeler is my go to way of peeling the sweet potatoes. The skins are quite tough and need a decent peeler or it can be hard work. Be careful not to slip.
I do also love to make these potatoes in my Tefal Actifry. But that is not required. I just love to roast in my airfryer!

My Roasted Sweet Potatoes can be roasted until nearly cooked ahead of time (up to a few days or longer if frozen) and then finished off and reheated in the oven.
Leftover Garlic Roasted Sweet Potatoes
There are as many uses for leftover sweet potatoes as their are fresh! Add leftovers to a salad, a soup or just eat them straight out of the fridge.
Leftovers can be frozen and reheated. Either in the microwave, oven or even fried in a pan for extra crispiness.
Garlic Roasted Sweet Potatoes Tips
Make sure the potato cubes have a good amount of space between them on the tray. If you overcrowd the baking tray, they have a tendency to steam rather than roast.
Ovens have a habit of not cooking evenly, even if you just bought a new one (annoying!). I do like to keep an eye on anything that I’m roasting and turn the tray a couple of times during the cooking process if needed.
