What you’ll love about this recipe
- It’s simple! This dish calls for just six ingredients (including salt and pepper) that require very little prep work. And while it does take an hour to prepare, all but ten minutes of that time is hands-off, giving you plenty of time to make ready the rest of your meal. Additionally, this recipe does not require any special kitchen equipment and is a breeze to clean up.
- It’s delicious! Although raw radishes have a bit of bite, when cooked up they are actually quite mild in flavor. That’s not to say that this dish is mild in flavor. Tossed in plenty of butter, fragrant rosemary and garlic, and salt and black pepper, it’s anything but!!! Those flavors combined with the fluffy interior of the radishes and the perfectly crispy, caramelized bottoms, make them beyond amazing!
- It’s healthy! Say what?!? Healthy AND delicious?!? That’s right!!! These smashed radishes tick all the boxes. This dish is gluten-free, vegetarian, and vegan adaptable. It’s also low-carb/keto-friendly and low in calories.

Ingredients (+ notes & substitutions)

- Radishes: You’ll need one pound of firm radishes for this recipe. They should be rinsed clean of any dirt and debris, patted dry, and trimmed. When cooked, radishes are mildly flavored and starchy like a potato. I’d be surprised, even if you’re not typically a fan, that you wouldn’t like them when prepared in this manner.
- Unsalted butter: This recipe can easily be adapted to a vegan diet, by swapping the butter for olive oil.
- Garlic: Two smaller-sized cloves.
- Fresh rosemary: The peppery, lemony, and piney notes of the rosemary pairs exceptionally well with the buttery roasted radishes. If you’re not a fan of rosemary or don’t have any, you could substitute it for fresh thyme. In a pinch, using dried rosemary is acceptable; if you do so, you’ll need just 1/2 tablespoon rather than 1 1/2 tablespoons.
- Sea salt: Coarse!!!
- Black pepper: Preferably freshly cracked.
How to make smashed rosemary garlic roasted radishes (+ tips):
1. In a medium saucepan, add the radishes and enough water to cover them by one inch. Bring to a boil, then cover, reduce to a simmer, and cook for 20-minutes, until fork tender.

2. Meanwhile, preheat your oven to 400 degrees. For easy clean-up, line a large baking sheet with parchment paper and set it aside. If you don’t have parchment paper, tinfoil would also work.
3. Drain the radishes and allow them to rest for 5-10 minutes in a colander over the sink.
4. Melt the butter in a small saucepan (you can use the same one you boiled the radishes in). Stir in the garlic, rosemary, and sea salt. Add the radishes and stir to coat.

5. Transfer the radishes to the prepared baking sheet and arrange them in a single layer. Use a fork to gently smash the radishes. Drizzle the remaining butter mixture atop the radishes then sprinkle with black pepper, to taste.

6. Bake for 25-30 minutes until slightly browned and crispy. Serve warm.

I am a huge radish lover - always plant a few rows in our garden. I have always eaten them raw, or added to a cold salad. I love the idea of roasting them! I saved this recipe to use this summer!

I hope you enjoy them roasted as much as I do! They are definitely more mildly flavored when roasted - so different but still tasty.
