How to Make Herby Potatoes & Onion

Step 1: Preheat your oven to 200°C (400°F).

Step 2: Wash and cube 4 medium potatoes into bite-sized pieces for even roasting.

Step 3: Peel and slice 1 large onion into thin wedges to caramelize perfectly.

Step 4: In a large bowl, combine the potatoes, onions, 3 tablespoons of olive oil, 2 cloves of minced garlic (optional), 1 teaspoon of dried rosemary (or a few fresh sprigs), 1 teaspoon of dried thyme (or fresh), salt, and freshly ground black pepper. Toss everything together until well coated.

Step 5: Spread the mixture evenly on a baking tray lined with parchment paper or foil.

Step 6: Roast in the oven for 30–40 minutes. Halfway through, give it a good stir to ensure even cooking and browning.

Step 7: Once the potatoes are golden and crispy, and the onions are soft and caramelized, remove from the oven.

Step 8: Garnish with freshly chopped parsley and serve warm.

Useful Tips

Soak the potatoes: For extra crispy potatoes, soak the cubed potatoes in cold water for 20–30 minutes before roasting. Then, dry them thoroughly with a clean towel to remove excess moisture.

Cut evenly: Make sure to cut the potatoes into similar-sized pieces so they cook evenly and finish roasting at the same time.
Use fresh herbs if possible: Fresh rosemary and thyme add a wonderful aroma and flavor. If using dried herbs, crush them lightly before mixing to release more flavor.
Don’t overcrowd the pan: Spread the potatoes and onions in a single layer with space between pieces. This helps them roast evenly and become crispy rather than soggy.

Stir halfway through roasting: This ensures even browning and prevents sticking.
Experiment with spices: Add a pinch of smoked paprika, chili flakes, or garlic powder for a twist.
Serve immediately: These potatoes taste best when served hot and fresh from the oven.
