Low-Carb Easy Roasted Radishes Recipe
Roasted radishes are a great alternative for potatoes, but they are low-carb and take just 30-35 minutes in the oven. Of course, radishes taste different from potatoes. Still, different can be good, especially when a healthier substitute tastes excellent roasted and makes a great addition to any main dish.

Yesterday, I was contemplating what to cook for my family this weekend. That’s how this roasted radish salad came to be! My kids love potatoes no matter how you prepare them, but potatoes are relatively high in calories and are quite starchy. I considered how I could make a potato dish a bit healthier and low carb. As I searched for inspiration, the idea of making the same potato recipe I usually make when roasting potatoes but substituting a more nutritious ingredient for the potatoes came to me. This is where radishes came to mind.
Radishes are common in my kitchen and meals in the spring. Some of my favorite ways to incorporate radishes are in salads like the Creamy Spring Radish & Cucumber Salad, Refreshing Radish Salad with Cucumber & Mint, and Simple & Crisp Radish, Corn, & Cucumber Salad. These salads are cold, so this warm salad recipe changes things up!
