Ingredients for Rosemary Roast Potatoes
Main Ingredients
- 2 kg Maris Piper potatoes, peeled and chopped into even-sized pieces
- 5 tbsp olive oil, plus a little extra for drizzling
- 4 sprigs fresh rosemary (thyme can be used as a substitute)
- Salt, to taste
Ingredient Notes & Helpful Substitutions
- Potatoes: Maris Piper potatoes are ideal because they become fluffy inside while crisping well. Yukon Gold or Russet potatoes also work if needed.
- Rosemary: Fresh rosemary is best for aroma and flavor, but dried rosemary can be used in a pinch – use 1–2 teaspoons. Thyme is another excellent substitute.
- Olive Oil: Choose regular or light olive oil for roasting. Extra-virgin olive oil works too but may smoke at higher temperatures; monitor carefully.
- Salt: Flaky sea salt gives the nicest finish. Add some before roasting and more to taste once cooked.
Step-by-Step Instructions
Step 1 – Prep and Par-Boil
Peel the potatoes and chop them into evenly sized chunks so they cook at the same rate. Place them in a large pot of water with the four rosemary sprigs and a generous pinch of salt. Bring to a boil and par-boil for about 12 minutes. The potatoes should yield slightly when pierced with a knife – not too firm, but not soft enough to fall apart.
Step 2 – Heat the Oil
While the potatoes are boiling, preheat your oven to 200°C (390°F). Pour 2–3 tablespoons of olive oil into a large baking dish or roasting tray. Place the tray in the oven so the oil becomes piping hot. This step is key: the instant the potatoes touch the oil, they should sizzle. That sound signals the beginning of a perfectly crisp crust.
Step 3 – Rough Up the Potatoes
Once par-boiled, drain the potatoes and discard the rosemary stems (leave any loose leaves, they add flavor). Return the potatoes to the hot pot, cover with a lid, and give them two or three firm shakes. This roughens the edges so they crisp beautifully.
Step 4 – Roast for the First 45 Minutes
Carefully remove the hot baking tray from the oven. Add the potatoes, they should immediately sizzle in the hot oil. Drizzle additional olive oil over the top, sprinkle with salt, and place the tray in the oven. Roast for 45 minutes.
Step 5 – Turn and Finish Roasting
Remove the tray, flip the potatoes so all sides get exposure to the heat, and roast for another 45 minutes or until they reach a deep golden color with crisp, crunchy edges. They should feel firm on the outside and soft in the center when tested with a fork.
Pro Tips for Success
- Don’t over-boil. Over-softened potatoes may break apart too much and lose their ability to crisp. Look for slight resistance when pierced.
- Use very hot oil. Heating the oil beforehand ensures that irresistible sizzle that leads to maximum crunch.
- Leave space on the tray. Crowded potatoes steam rather than roast. Spread them out for quicker, crispier results.
- Shake vigorously. Roughing up the edges creates more surface area, giving that signature crunchy crust.
- Roast undisturbed. Avoid opening the oven too often. Consistent heat helps them brown evenly.
- Finish with flaky salt. A sprinkle after cooking enhances both flavor and texture.
Flavor Variations
- Garlic Rosemary: Add whole smashed garlic cloves to the roasting tray during the second half of baking.
- Lemon Herb: Finish with freshly grated lemon zest and extra rosemary leaves.
- Smoky Paprika: Toss potatoes in 1 teaspoon smoked paprika before roasting.
- Thyme & Bay Leaf: Replace rosemary with thyme sprigs and add a couple of bay leaves during the boil.
- Chili Crunch: Add a little mild chili flakes for a gentle kick.
Serving Suggestions
These rosemary potatoes pair beautifully with roasted vegetables, grilled chicken, tofu, fish, or festive mains like holiday roasts. Serve them with a creamy dipping sauce, vegan aioli, or simple gravy. They’re also fantastic alongside salads, stews, or a Sunday-style dinner plate. Their versatility makes them ideal for both casual family meals and elegant gatherings.
Storage and Freezing Instructions
- Refrigerate: Store leftovers in an airtight container for up to 2 days. Reheat in the oven at 200°C (390°F) for about 20–30 minutes for restored crispiness.
- Make Ahead – Stage Options:
- Stage 1 (peeled & chopped): Store covered in the fridge for 1–2 days.
- Stage 2 (after par-boiling): Cool completely, refrigerate 1–2 days, then roast as directed.
- Stage 3 (fully roasted): Refrigerate 1–2 days and reheat in the oven.
- Freezing: Freeze after Stage 2 or Stage 3. Defrost before finishing the roast or reheating.
This flexible prep timeline makes the recipe perfect for busy holidays or big gatherings.

Notes
FAQ About Rosemary Roast Potatoes
How do I know when the potatoes are par-boiled correctly?
Par-boiled potatoes should offer slight resistance when pierced with a small knife. If the knife slides in too easily, they’re overdone and may crumble. If it barely penetrates, they need more time. The perfect middle point ensures they hold shape while still roughing up nicely.
Can I use dried rosemary instead of fresh?
Yes, dried rosemary works, though the flavor is slightly different. Use about 1–2 teaspoons, and add more at the roasting stage rather than during boiling. Fresh rosemary provides brighter aroma and texture, but dried is a good backup.
Why is heating the oil so important?
Hot oil jump-starts the crisping process. When the potatoes hit sizzling oil, their exterior begins to fry lightly, creating the crunchy crust you want. Adding potatoes to cold oil leads to soft, pale results.
Can I make these potatoes ahead for a holiday meal?
Absolutely. This recipe includes three preparation stages with make-ahead options. Many cooks prefer stopping after par-boiling (Stage 2), refrigerating, and roasting on the day for the freshest texture with minimal stress.
What are the best potatoes for roasting?
Maris Piper potatoes are ideal because they’re starchy and fluffy inside. Russet or Yukon Gold potatoes are excellent alternatives with similar roasting qualities. Waxy potatoes are less suitable because they don’t rough up as well.
These Rosemary Roast Potatoes are simple, flavorful, and naturally crisp thanks to a few time-tested techniques. Whether you’re serving a holiday crowd or adding a delicious side to a weekday dinner, this method guarantees reliable results with minimal effort. With outstanding crunch, a fragrant rosemary aroma, and a beautifully golden finish, this recipe is sure to become a staple in your kitchen.
