These easy Crispy Roasted Potatoes are the perfect side that everyone will love. Roasted to the perfect consistency we all love!

Potatoes are the bomb and there are so many different ways you can use them which is what I love. For this recipe, I made Crispy Oven Potatoes which are so crunchy on the outside, and fluffy on the inside. It has taken me years to try and figure this out, and I finally found the trick to really nailing that perfect potato consistency.

My secret weapon for nailing that consistency? Boiling and baking soda. More on that below but DO NOT skip these steps. I promise you that you’ll thank me later. Whip these bad boys up for a holiday dinner, or if you’re in the UK, your typical Sunday roast.

Crispy roasted potato ingredients on a counter: potatoes, butter, spices and more.

Ingredient Notes:

Potatoes: I like to use russet or baby potatoes for this roasted potatoes recipe as I feel I get the best flavor and consistency of the crispy but soft consistency I love.

Baking Soda: Do not skip the step of boiling your potatoes with baking soda. Baking soda will help your potatoes get crispy in the oven. This is the trick!

Thyme: I used fresh thyme for these crispy potatoes but you can also use dried thyme or swap out the thyme for a different herb like rosemary.

How to make crispy roasted potatoes:

1. Bring a large pot to a boil to boil your potatoes first.

2. In your pot, you’ll want to add salt and baking soda and then parboil them for 10 minutes. This is the step I mentioned before that you don’t want to miss because it helps give you the perfect consistency.

3. While your potatoes are cooking, preheat your oven and line 1-2 baking sheets with parchment paper.

Cut and peeled potatoes in a white bowl on counter after boiling.

4. When your potatoes are done, remove them from the water and add them into a large bowl where you’ll then throw in your spices such as: salt & pepper, onion powder, oil, garlic, and/or butter.

Cooked potatoes in a casserole dish covered with salt & pepper, onion powder, oil, garlic, and/or butter. Next step is to put them in the oven.

5. Once you stir together everything in your bowl, put the potatoes on your baking sheet and make sure there’s some breathing room next to each potato and they’re facing cut-side down before you roast potatoes in the oven for 50 minutes. You’ll want to remove them at the 30-minute mark to flip them and distribute the thyme evenly on them before cooking for the last 20 minutes until golden brown to perfection.

Expert Tips & FAQ:

How to make potatoes crispier? Baking soda! It sounds weird but it works. The baking soda makes the water alkaline which helps breakdown the surface of the potatoes and really helps get that crispiness you want once you add them to the oven.

Is it necessary to boil potatoes before roasting? Not necessary but this can help get the perfect consistency and crispiness. Make sure you boil them but leave them a bit al dente and they will crisp up perfectly in the oven.

What oil is best for roasting potatoes? You can use whatever you prefer. Olive oil, avocado oil, or vegetable oil all work.

Why does soaking potatoes make them crispier? This step removes excess potato starch from the outside. This will help with the crisping up of the potatoes when they bake or roast.

I got a little impatient because they took longer to cook than I wanted because they smelled SOOOOO good when they were roasting in the oven. I wanted to eat them ASAP. The cook time is definitely worth the wait/patience.
