Herb Roasted Potatoes Parsnips

There's something almost magical about the moment when roasted potatoes and parsnips hit a hot pan—that first sizzle, the way the kitchen fills with herb-infused steam. I discovered this particular combination on a gray Sunday afternoon when I was trying to rescue a dinner that had gone sideways, and honestly, these golden vegetables ended up stealing the show. The sweetness of the parsnips plays so beautifully against the earthiness of the potatoes, especially when you've got fresh rosemary and thyme doing their quiet work in the background.

I made this for my partner's family dinner last winter, and his mother—who is not easily impressed—asked for the recipe before dessert was even served. That moment taught me that simple food done right beats complicated dishes every single time. The ease of it meant I could focus on setting a nice table and actually enjoying my guests instead of panicking in the kitchen.

Ingredients

• Baby potatoes: Use waxy varieties like fingerlings or baby reds if you can find them; they hold their shape better than starchy ones and won't fall apart during roasting.
• Parsnips: The ones with more length and slenderness are usually sweeter and less fibrous than the thick, pale ones.
• Olive oil: Don't shy away from using a decent quality oil here—it carries the flavor of the herbs and helps everything get properly golden.
• Fresh rosemary: Dried will work in a pinch, but fresh makes such a difference; use about one-third the amount if you only have dried.
• Fresh thyme: Strip the tiny leaves from the stems before chopping—it's easier than it sounds and makes a huge difference in texture.
• Garlic: Mince it finely so it distributes evenly and gets slightly crispy around the edges of the vegetables.
• Sea salt and black pepper: Finish grinding your pepper fresh; pre-ground gets tired and dusty-tasting surprisingly fast.

Instructions

Get your oven ready and prep your pan:

Preheat to 220°C (425°F) and line your baking sheet with parchment paper—this prevents sticking and makes cleanup almost laughably easy. You want the oven properly hot before the vegetables go in so they start crisping immediately.

Combine everything in a bowl:

Toss the halved potatoes and parsnip batons with the olive oil, herbs, garlic, salt, and pepper until every piece is glossy and coated. This is where the real flavor-building happens, so don't rush it—take thirty seconds to make sure nothing's hiding at the bottom of the bowl.

Spread and roast:

Arrange everything in a single layer on your sheet pan, which means they'll brown instead of steam. After about 17 to 18 minutes, give everything a gentle stir and scatter the pieces so uncooked sides hit the hot pan.

Finish until golden:

The potatoes and parsnips should turn a deep amber color and feel tender when you pierce them with a fork, which usually takes about 35 minutes total. Don't be tempted to pull them out early—the caramelization is what makes them taste like they're worth eating.

Plate and serve:

Transfer to a serving dish while they're still warm, add a small handful of fresh herbs on top if you're feeling fancy, and serve immediately. They're honestly best eaten within minutes of coming out of the oven.

My favorite memory with this dish is watching my nephew, who claims to hate vegetables, devour an entire handful straight from the pan while it was still hot enough to burn his fingers. He was more careful after that, but the fact that he wanted seconds made me realize how much better roasted root vegetables are than any raw veggie tray.

The Magic of Root Vegetables

Roasting brings out a natural sweetness in root vegetables that you simply cannot get any other way—the dry heat caramelizes the natural sugars and creates this almost savory-sweet complexity. Parsnips especially transform under heat; what might taste slightly bitter or overly earthy raw becomes mellow and almost chestnut-like when roasted properly. Once you've experienced truly good roasted parsnips, you'll understand why people get excited about them at farmers markets.

Customizing Without Losing the Plot

The beauty of this recipe is that it's flexible without being fussy—you can swap in carrots, sweet potatoes, turnips, or even beets without fundamentally breaking what makes this dish work. The key is keeping your pieces similar in size and not overthinking it; the herb mixture and roasting technique are what matters. I've made this with different combinations depending on what looked good at the market, and honestly, it's hard to mess up once you understand the basic principle.

Timing and Make-Ahead Strategies

You can prep your vegetables and herbs hours ahead of time, keeping everything separate in the fridge until you're ready to toss and roast. The actual cooking only takes 50 minutes from start to finish, which makes this perfect for weeknight dinners or last-minute side dishes when guests are already on their way. If you do want extra-crispy potatoes, soak the halved potatoes in cold water for 30 minutes before draining and patting completely dry—this removes excess starch and helps them crisp up beautifully.

• Keep your oven temperature steady; cracking the door or checking too often drops the heat and slows browning.
• Stir the vegetables at the halfway mark, making sure pieces that were on top move to the bottom so everything gets equal color and tenderness.
• If your kitchen tends to run cool, add five extra minutes; if your oven runs hot, check at the 30-minute mark.
