Start by peeling the potatoes and cutting them into thick wedges. Try to keep the pieces similar in size so they cook evenly in the oven. Rinse them briefly to remove excess starch and pat dry with a towel.
Dry potatoes roast better and develop crispier edges. I usually let them sit for a few minutes after drying so the moisture completely disappears. This small step really improves the texture.
In a large bowl, whisk together olive oil, lemon juice, broth, garlic, oregano, Dijon mustard, salt, pepper, and lemon zest. The mixture should smell fresh, garlicky, and bright.
The broth keeps the potatoes soft while the olive oil helps them crisp beautifully. Dijon mustard blends the lemon and oil together while adding a subtle tangy flavor that makes the dish taste richer.
Add the potato wedges into the bowl and toss them thoroughly until every piece is coated with the marinade. Make sure the garlic and oregano spread evenly across the potatoes.
I like letting the potatoes sit in the mixture for about 10 minutes before baking. This gives them time to absorb more flavor and makes the final result even more delicious.
Spread the potatoes in a single layer inside a large baking dish. Pour all the remaining marinade over the top so nothing goes to waste.
Avoid overcrowding the pan because tightly packed potatoes steam instead of roast. Giving them enough space helps create crispy edges while keeping the centers fluffy.
Bake the potatoes in a preheated oven at 400°F (200°C) for about 25 minutes. Carefully flip them using tongs or a spatula, then continue roasting for another 20 to 25 minutes.
As they cook, the broth slowly reduces and the potatoes absorb all the lemony flavor. The edges become golden brown while the insides stay soft and creamy
Once the potatoes are crispy and fork tender, remove them from the oven. Sprinkle fresh parsley or extra oregano over the top before serving.
I usually spoon some of the roasted lemony juices from the pan over the potatoes just before serving. That final drizzle adds even more flavor and keeps them extra juicy.
