These roasted radishes are tossed in avocado oil and seasoned with salt and pepper, then roasted until crispy and caramelized. The addition of rich, nutty browned butter with garlic enhances the flavor, making this low-carb and keto-friendly dish a flavorful and satisfying option for anyone on a ketogenic diet or looking to reduce carbs. This recipe is easy to make, full of flavor, and the perfect accompaniment to meats, seafood, or even as a standalone snack.

Ingredients:
- 2 bunches radishes (about 3 cups)
- 1 tablespoon neutral oil (such as avocado oil)
- 1 tablespoon salt
- 1 tablespoon freshly cracked black pepper
- 2 tablespoons butter (see Notes)
- 1 clove garlic, pressed or minced
- ¼ teaspoon lemon zest (optional)
- 1 sprig fresh thyme (optional)
Instructions:
- Preheat the oven to 450º F (230º C).
- Prepare the radishes: Trim off the stems and any root tails. Halve smaller and medium-sized radishes, and quarter the larger ones.
- Spread the radishes on a baking sheet and toss with neutral oil, salt, and freshly cracked black pepper. Roast in the oven for 20-30 minutes, stirring every 10 minutes, until the radishes are browned and slightly wrinkled, but not burned.
- While the radishes are roasting, prepare the browned butter. Heat the butter in a small, light-colored saucepan or skillet over medium heat. Stir occasionally and watch carefully for 3-5 minutes as the butter turns a deep golden brown and releases a nutty aroma. Remove from heat immediately once it reaches the desired color or when it begins to smell nutty.
- Let the browned butter sit for 2-3 minutes, then stir in the garlic and a pinch of salt. Cook, stirring, until the garlic becomes soft and fragrant.
- Once the radishes are done roasting, remove them from the oven and drizzle with the browned butter sauce. Toss to coat. Optionally, sprinkle with lemon zest and garnish with thyme sprigs. Serve immediately.
Why You’ll Love This Recipe
These roasted radishes with browned butter make for an irresistibly rich and savory side dish. The radishes’ natural sweetness is enhanced through roasting, while the browned butter adds a nutty depth that pairs beautifully with the garlic, lemon zest, and thyme. Low-carb and keto-friendly, this dish is a perfect addition to any meal, whether as a side to meats or a light, flavorful snack. It’s simple, quick to prepare, and packed with flavor.
Tips
- Watch the Butter Closely: Browning butter requires attention. Once it reaches a deep golden brown, remove it from heat right away to prevent burning.
- Don’t Overcrowd the Radishes: Spread the radishes out in a single layer to ensure they roast evenly.
- Tossing Halfway: Stir the radishes halfway through the roasting time to ensure they brown evenly and get a nice crisp on all sides.
- Use Light-Colored Cookware for Browning Butter: A light-colored saucepan helps you monitor the color of the butter to prevent burning.
Variations and Substitutions
- Herb Variations: If you don’t have thyme, rosemary, or oregano would work well in place of it.
- Butter Alternatives: For a dairy-free version, use ghee or coconut oil to brown.
- Lemon Zest: For an extra citrusy flavor, try substituting lemon zest with orange or lime zest.
- Add Cheese: For extra richness, sprinkle grated Parmesan or crumbled feta over the radishes before serving.
