Why Make This Crispy Smashed Turnips Roasted Garlic Butter
This recipe is a game-changer for anyone looking to diversify their vegetable intake. Turnips are significantly lower in calories and carbohydrates than potatoes, making them a fantastic option for keto or low-carb lifestyles. The “smashing” technique increases the surface area, which means more room for those crispy, jagged edges we all crave. When you combine that crunch with the mellow, sweet notes of roasted garlic butter, you create a side dish that often outshines the main course. It is simple, elegant, and incredibly satisfying.
Ingredients
- 1 pound small to medium purple-top turnips, ends trimmed
- 3 tablespoons unsalted butter, softened
- 3 tablespoons extra virgin olive oil
- 4 cloves garlic, minced
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly cracked black pepper
- 1 tablespoon fresh parsley, finely chopped
- 1/2 teaspoon red pepper flakes (optional)
- Optional: 2 tablespoons grated Parmesan cheese
Directions
Step 1: Parboiling the Turnips
Start by placing your trimmed turnips into a large pot of salted water. Bring the water to a rolling boil over high heat. Reduce the heat slightly and simmer the turnips for about 12 to 15 minutes, or until they are fork-tender but not falling apart. While the turnips boil, preheat your oven to 425°F (220°C). Drain the turnips in a colander and let them steam dry for 5 minutes. Drying them is crucial for achieving maximum crispiness later.
Step 2: Smashing and Roasting
Line a large baking sheet with parchment paper or lightly grease it with olive oil. Place the warm turnips on the sheet, leaving plenty of space between them. Use the bottom of a heavy drinking glass or a potato masher to gently press down on each turnip until it is about 1/2-inch thick. Drizzle the smashed turnips with olive oil and season generously with salt and pepper. Flip them gently to coat both sides. Roast in the preheated oven for 25 to 30 minutes, flipping halfway through, until the edges are deep golden brown and crispy.
Step 3: Creating the Garlic Butter and Finishing
While the turnips finish roasting, whisk together the softened butter, minced garlic, parsley, and red pepper flakes in a small bowl. Once the turnips are crispy, remove the tray from the oven. Spoon a small dollop of the garlic butter onto each hot turnip, allowing it to melt and seep into the nooks and crannies. If you are using Parmesan, sprinkle it on now. Return the tray to the oven for just 2 more minutes to mellow the garlic. Serve immediately while hot and sizzling.
Expert Tips for Perfect Crispy Smashed Turnips Roasted Garlic Butter
To get the best results, always choose smaller turnips. Large turnips can sometimes be woody or overly bitter. If you find your turnips are particularly bitter, adding a teaspoon of sugar to the boiling water can help neutralize the flavor. Ensure you pat the turnips completely dry after boiling; moisture is the enemy of a good crunch. Finally, do not crowd the pan. If the turnips are too close together, they will steam instead of roast.
Delicious Variations
You can easily customize this recipe to suit your palate. For a Vegan Version, swap the butter for a high-quality vegan buttery spread or simply use more olive oil infused with garlic. If you want a Loaded Version, top the finished turnips with crispy bacon bits and a dollop of sour cream. For a Lemon Herb Twist, add a teaspoon of lemon zest and fresh thyme to the butter mixture for a bright, citrusy finish that cuts through the richness.
Frequently Asked Questions
Do I need to peel the turnips before boiling?
For young, small turnips, the skin is very thin and edible, so peeling is optional. For larger, older turnips, the skin can be tough and bitter, so it is best to peel them with a vegetable peeler before starting.

Can I make these in an air fryer?
Yes! After parboiling and smashing, place them in a single layer in your air fryer basket. Air fry at 400°F for 10-15 minutes, flipping halfway through, until crispy. Add the garlic butter at the very end.
Are turnips a good keto substitute for potatoes?
Absolutely. Turnips have about 6 grams of net carbs per cup, compared to roughly 30 grams in a potato. They provide a similar texture when roasted and smashed.
How do I store and reheat leftovers?
Store leftovers in an airtight container in the fridge for up to 3 days. To maintain the crunch, reheat them in the oven at 375°F or in an air fryer. Microwave reheating will make them soft.
Why are my turnips bitter?
Bitterness is common in larger turnips. To reduce this, choose smaller vegetables, peel them deeply, and ensure you season well with salt and fat (like butter), which naturally masks bitter notes.
