Crispy Garlic Butter Roasted Radishes (The Ultimate Keto Potato Substitute)
If you have been navigating the ketogenic lifestyle for a while, you likely miss one thing above all else: roasted potatoes. While cauliflower is a fantastic versatile vegetable, it doesn't quite capture that satisfying, starch-like texture of a roasted spud. Enter the humble radish. When raw, radishes are peppery, crunchy, and sharp. However, a magical transformation happens when you roast them at high heat. They lose that spicy bite entirely, becoming tender, juicy, and shockingly similar to a new potato. Rich in potassium, Vitamin C, and gut-healthy fiber, radishes are a nutritional powerhouse that fits perfectly into your macros. These Crispy Garlic Butter Roasted Radishes are tossed in olive oil, roasted until golden, and then finished with a rich garlic herb butter that elevates them from a simple garnish to the star of your dinner plate. At only 3g net carbs per serving, this is the low-carb side dish hack you have been waiting for.
The Masterplan
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or a silicone mat.
Wash the radishes thoroughly and cut off the stems and root ends. Slice large radishes into quarters and smaller ones in half to ensure even cooking.
In a large bowl, toss the prepared radishes with olive oil, sea salt, and black pepper until fully coated.
Spread the radishes cut-side down on the baking sheet. This ensures the cut surface gets nice and crispy. Roast for 20-25 minutes, or until the radishes are tender and the skins are wrinkled and golden.
While the radishes are roasting, whisk together the melted butter, minced garlic, and dried thyme in a small bowl.
Remove the radishes from the oven and drizzle the garlic butter mixture over them. Toss gently on the pan to coat. If using Parmesan, sprinkle it over the top now.
Return to the oven for another 5 minutes to cook the garlic and crisp up the edges.
Remove from oven, garnish with fresh parsley, and serve immediately as a side to steak or chicken.
