Cajun Sweet Potatoes (346 calories) Recipe Book: Jamie Oliver - 5 Ingredients Review: ⭐️⭐️⭐️⭐️⭐️ I absolutely loved these. I have to admit, I’ve got a thing for sweet potato 🍠. Putting Cajun spice on them takes them to a whole new level though. The garlic yoghurt sauce was pretty great too. Aga conversion: Roasting tray on middle set of runners in the Roasting Oven. I did mine for about 45 minutes as my oven was running hot. Will I make this again? Absolutely, I loved it.
