Ingredients Needed
To make these crispy and golden low-carb roast potatoes, you’ll need:
1 kg turnips or radishes – peeled and cut into 5cm chunks
2 tbsp olive oil(or melted duck fat for extra flavor)
1 tsp garlic powder
1/2 tsp paprika (optional, for color)
Saltflakes – to season
Fresh herbs(rosemary, thyme, or parsley), optional for garnish
How to Make Keto The Best Roast Potatoes
Here’s how to transform humble turnips or radishes into golden keto-friendly perfection:
Preheat and Prep
Preheat your oven to 220°C (200°C fan-forced). This high heat ensures a crispy, golden exterior.
Peel the turnips (or radishes, if you’re using them) and cut into 5cm chunks—just like you would with regular potatoes.
Parboil the Veggies
Place the turnips or radishes in a large saucepan. Cover with cold water, add a pinch of salt, and bring to a boil. Once boiling, reduce heat and let them simmer for 5-7 minutes until slightly tender. Don’t overdo it—you want them firm, not mushy.
Shake Things Up
Drain the turnips or radishes thoroughly. Return them to the hot saucepan and place over low heat for a minute to evaporate any remaining moisture.
Now, shake the saucepan vigorously! This roughens up the edges, creating those glorious crispy bits we all love. Alternatively, use a fork to lightly scrape the surface.
Heat the Fat
Add olive oil (or duck fat for extra richness) to a large roasting pan and place it in the oven for 5 minutes to get sizzling hot. This step is key for achieving that crispy coating.
Roast to Perfection
Carefully toss the turnips or radishes in the hot oil, ensuring they’re well coated. Spread them evenly in the pan, leaving space between chunks to prevent steaming.
Roast for 30 minutes, then flip each piece using tongs for even browning. Roast for an additional 20-25 minutes until the edges are golden, crispy, and irresistible.
Season and Serve
Remove from the oven, sprinkle with garlic powder, paprika (optional), and a generous amount of salt flakes. Garnish with fresh herbs like rosemary or thyme for a fancy finishing touch. Serve immediately and watch them disappear!
Storage & Serving Suggestions
Storage Tips
So, you made a batch of these keto roast potatoes, and now you’ve got leftovers (lucky you!). Here’s how to store them without losing that crispy goodness:
Cool Before Storing: Let the turnips or radishes cool completely before popping them in the fridge. Putting them in warm will turn them soggy… and nobody wants that.
Use Airtight Containers: Store the roast potatoes in an airtight container or a resealable bag to keep them fresh. They’ll stay good for 3-4 days in the fridge.
Reheat Like a Pro: For best results, reheat them in the oven at 200°C (400°F) for about 10-15 minutes. The hot oven brings back the crispiness like magic! Avoid the microwave—it’ll turn them soft and sad.
Freezing? Not This Time: Unfortunately, these don’t freeze well. The texture gets mushy once thawed… so just stick to making them fresh and fabulous.

Note
As a mom of three (and wife to a carb-loving husband), I’m always looking for ways to make my keto creations family-approved. When I first served these keto roast potatoes, I held my breath—because, let’s be real, kids can spot a veggie swap from a mile away! But guess what? They devoured them. My youngest even asked for seconds, and my husband said, “Are you sure these aren’t potatoes?” (Yes, honey. I’m sure.)
