Every time I share a recipe for radishes, I get a lot of confused people who have never heard of cooking radishes.

I get it – they seem like a thing you just eat raw, maybe sliced over salad or pickled on a taco. But let me tell you – cooked radishes are basically a completely different vegetable compared to raw! They mellow out and lose almost all of that spicy bite. They get nice and tender. They’re not starchy like a potato, but more juicy with a little pop to each bite. So dang good!

Our fried radishes and loaded radishes are already super popular, so we thought we’d share yet another way to enjoy them. Enter these roasted radishes!

These make a great side dish with just about anything you’d otherwise serve with potatoes. Try them next to our keto meatloaf sometime. So good!

Ingredient Notes:

ingredients for roasted radishes.

Radishes – You’ll need a pound of fresh radishes, halved.

Butter – We like the flavor of butter on our roasted radishes, but olive oil will also work.

Seasoning – Garlic powder and onion powder will go on the radishes before roasting them, with some salt and pepper to taste before serving.

Grated Parmesan Cheese – We like to sprinkle this on top of the radishes with some parsley just before serving!

Why We Love This Recipe:
  • It’s not quite the same as potatoes, but these roasted radishes make for a good low carb substitute!
  • They are quick and easy to prepare and you can serve them up as a side to just about anything.
  • Raw radishes have a peppery bite to them that really mellows out once cooked. They’re basically two different foods!

How To:

  • Slice – Cut the radishes into halves. If there are any extra large ones, quarter them. We want them all a similar size so they cook evenly.
  • Season – Combine the melted butter, garlic powder, and onion powder.
  • Combine – Pour the butter over the radishes and toss to coat.
  • Roast – Bake for 25-30 minutes or until they are browned and tender. Sprinkle with Parmesan, parsley, salt, and pepper and then serve.
Helpful Tip!

There’s no reason you can’t switch up the seasoning on these roasted radishes! Maybe you like it spicy? Add some cayenne pepper or Cajun seasoning! Dry ranch seasoning makes a great flavor! Pretty much any mix of spices and seasonings you like will work here.

Roasted Radishes

These roasted radishes make a great side dish for just about any meal. They look a lot like potatoes and have a more mild taste than raw radishes, but the texture is more juicy than starchy. These are a must try!

Yield 4
Prep Time 10 minutes
Cook Time 30 minutes
Total Time 40 minutes


  • 1 pound fresh radishes
  • 2 tablespoons butter, melted
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 2 tablespoons grated Parmesan cheese
  • Parsley, for garnish
  • Salt and pepper, to taste


  1. Preheat oven to 425 degrees.
  2. Wash and trim the ends from the radishes. Cut the radishes in half and place in a large bowl.
  3. Toss with the melted butter, garlic powder, and onion powder to coat.
  4. Place radishes on a rimmed baking sheet in a single layer and roast for 25-30 minutes, stirring halfway through cooking, until radishes are browned and tender.
  5. Sprinkle with parmesan cheese, parsley, and salt and pepper before serving.


Roasting radishes takes a lot of the 'bite' out of the radishes - they're much more mellow than raw radishes.

Any blend of seasonings will work well here. Dry ranch seasoning is very popular and cajun seasoning is also tasty!
