A simple and delicious dish of fragrantly spiced scalloped sweet potatoes, roasted until crisp. Comfort food that’s smart enough for company!
Do you ever get annoyed with yourself for not thinking of something sooner?
I do.
All. The. Time.
Like these delicious roasted scalloped sweet potatoes. I could kick myself when I think of all the time that we could have been enjoying eating them, if only I’d thought of them!

Scalloped potato roast – white potatoes
I make a scalloped potato roast using regular white potatoes quite frequently. We call it ‘sideways potatoes’ because the slices of potato are tipped on their sides. It looks gorgeous and also ensures that every single slice of potato has a crispy, crunchy edge. Yum.
It’s a great recipe because you can prepare it an advance. Then, about an hour before you’re ready to eat, you can just pop it into the oven and you’re all set.
I still can’t believe that despite making it regularly for YEARS, it’s only occurred to me now to give sweet potatoes the same treatment. I mean REALLY!

Scalloped roasted sweet potatoes
To be honest, I’ve always been a bit boring with sweet potatoes. My daughter Kipper loves them simply baked in their jackets, so normally, I just stab them a few times with a fork and then bake them till soft. Butter, salt and pepper, and she’s a happy bunny!
Perhaps that’s why this recipe didn’t come to mind until now. We got sweet potatoes in our organic vegetable box and for whatever reason, I just didn’t feel like baking them. Then, as I was planning our menus for the week and thinking of making scalloped potatoes, inspiration struck!
I could make scalloped SWEET potatoes!

Easy and delicious recipe
Just like with white potatoes, this scalloped sweet potatoes recipe is super easy. You simply need to scrub and slice the sweet potatoes, then mix with oil and seasoning. Arrange in a dish, bake, and Bob’s your uncle!

I used warming spices to bring out the sweet and earthy flavours of the sweet potatoes. I also added a little vegetable stock to the bottom of the dish to keep the sweet potato slices from drying out. The stock evaporates as the dish cooks, so the slices of sweet potato are beautifully cooked and crispy when you’re ready to eat.

Scalloped sweet potatoes – ingredients
To make a dish of delicious roasted scalloped sweet potatoes, you will need:
- Sweet potatoes – of course!

- Salt
- Vegetable stock
You’ll also need a suitably sized baking dish, and a hot oven.

Are sweet potatoes good for you?
In a word, yes! Unlike white potatoes which are mostly starch, sweet potatoes contain complex carbohydrates, dietary fibre, and lots of beta-carotenes which give them their orange colour. Sweet potatoes are also a good source of vitamin A and contain moderate amounts of certain B vitamins and trace minerals.
Like other carbohydrate-dense foods, it’s good to cook and eat sweet potatoes with a little fat, in this case olive oil. This helps to slow the digestion and prevents a rapid increase in blood sugar levels.

Sounds delish and going to make this for a fall gathering! Can it be prepared or made ahead of time? Thanks!
Helen
Thanks Stephanie! You can prepare the sweet potatoes to the end of step 4 ahead of time and refrigerate, then continue to add the stock and bake when you’re 40 mins or so away from wanting to eat them. Alternatively, you can bake them earlier in the day for about 30 minutes, cool, and then bake again for 20-30 minutes to heat through and finish crisping up when you’re ready to eat them. I hope you enjoy them!
