FAQ
Keto Roasted “Potatoes” FAQ
Is this recipe keto-friendly?
Yes. Radishes are very low in carbs, making them an excellent substitute for potatoes on a ketogenic diet.
Can I use another vegetable instead of radishes?
Yes. Turnips or kohlrabi can be used as a low-carb alternative with a similar texture when roasted.
Can I make this recipe ahead of time?
Yes. Roast the radishes in advance and store them in an airtight container in the fridge for up to 3 days. Reheat in the oven to keep them crispy.
Can I adjust the seasoning?
Absolutely. You can add garlic powder, paprika, or rosemary for extra flavor. Adjust salt and pepper to taste.
Can I use only one type of oil?
Yes. You can use just olive oil or avocado oil if you prefer, though the sesame oil adds a subtle nutty flavor.
How should I serve it?
Serve warm as a side dish to keto meats like chicken, beef, or fish. Sprinkle Parmesan just before serving for best flavor.
Can I make them crispier?
For extra crispiness, cut the radishes into smaller pieces and roast on a single layer without overcrowding the pan. You can also broil for the last 2–3 minutes.
