Ingredients
Here is everything you need for the best Garlic Parmesan roasted potatoes:
For the Potatoes:
· 2 pounds baby Yukon Gold or red potatoes (or 4 large russet potatoes, cut into 1-inch chunks)
· 1 tablespoon salt (for the parboiling water)
· 4 tablespoons olive oil (or avocado oil)
· 6 cloves garlic, minced (about 2 tablespoons)
· ½ cup freshly grated Parmesan cheese, divided (plus extra for serving)
· 1 teaspoon salt
· ½ teaspoon black pepper
· 1 teaspoon dried oregano
· 1 teaspoon dried thyme (or 1 tablespoon fresh thyme leaves)
· ½ teaspoon smoked paprika (optional, for depth)
For Garnish:
· 2 tablespoons fresh parsley, finely chopped
· ¼ cup freshly grated Parmesan cheese
· Red pepper flakes (optional, for heat)
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius). Line a large, rimmed baking sheet with parchment paper or aluminum foil for easy cleanup. If using foil, lightly grease it with olive oil to prevent sticking.
Step 2: Parboil the Potatoes
If using baby potatoes, leave them whole or cut larger ones in half. If using russets, cut them into 1-inch chunks. Place the potatoes in a large pot and cover with cold water by at least 1 inch. Add 1 tablespoon of salt to the water. Bring to a boil over high heat, then reduce to a simmer and cook for 8 to 10 minutes. The potatoes should be slightly tender but not falling apart—a fork should meet some resistance. Drain the potatoes in a colander and let them steam dry for 2 to 3 minutes.
Step 3: Rough Up the Potatoes (The Secret to Crispiness)
Return the drained potatoes to the pot (or transfer to a large bowl). Give them a few vigorous shakes or stirs with a wooden spoon to rough up the surfaces. This creates a starchy, craggy coating that will become exceptionally crispy in the oven.
Step 4: Season the Potatoes
Drizzle the olive oil over the potatoes. Add the minced garlic, ¼ cup of the grated Parmesan cheese, salt, black pepper, dried oregano, dried thyme, and smoked paprika (if using). Toss well until every potato is evenly coated. The mixture will be sticky and fragrant.
Step 5: Arrange on Baking Sheet
Spread the seasoned potatoes in a single layer on the prepared baking sheet. Make sure they are not touching or overcrowded—leave a little space between each piece for air circulation. Overcrowding leads to steaming instead of roasting.
Step 6: Roast
Roast the potatoes in the preheated oven for 20 minutes. Remove the baking sheet from the oven and use a spatula to flip the potatoes. Sprinkle with another ¼ cup of Parmesan cheese. Return to the oven and roast for another 15 to 20 minutes, until the potatoes are deep golden brown, crispy on the outside, and fork-tender on the inside.
Step 7: Garnish and Serve
Remove the potatoes from the oven. Transfer them to a serving bowl or platter. Sprinkle immediately with the fresh parsley, the remaining Parmesan cheese, and red pepper flakes if desired. Serve hot.
Cooking Tips and Pro Tips for Best Results
· Do not skip the parboil: Parboiling starts the cooking process and ensures a creamy interior while allowing the exterior to get ultra-crispy. It is the single most important step.
· Rough up the surfaces: Shaking the parboiled potatoes in the pot creates small cracks and rough edges. These rough patches become exceptionally crispy and provide more surface area for the garlic and Parmesan to cling to.
· Use freshly grated Parmesan: Pre-shredded Parmesan contains anti-caking agents that prevent it from melting and browning properly. Grate your own from a block for the best flavor and texture.
· Do not overcrowd the pan: Crowding traps steam and makes the potatoes soggy. Use two baking sheets if necessary, and rotate them halfway through roasting.
· Flip halfway through: Flipping ensures even browning on all sides. Do not skip this step.
· Add garlic strategically: Mincing the garlic finely and tossing it with the oil ensures it coats every potato. If you add whole garlic cloves, they can burn. For a milder garlic flavor, add the garlic during the last 10 minutes of roasting.
· Let the potatoes rest: After roasting, let the potatoes sit on the baking sheet for 2 to 3 minutes before transferring. This allows the crust to set and prevents sticking.
Variations and Substitutions
· Garlic rosemary Parmesan potatoes: Replace the oregano and thyme with 1 tablespoon of fresh rosemary, finely chopped.
· Spicy garlic Parmesan potatoes: Add ½ teaspoon of cayenne pepper or red pepper flakes to the seasoning mix. Garnish with additional red pepper flakes.
· Lemon garlic Parmesan potatoes: Add 1 tablespoon of lemon zest to the seasoning mix. Squeeze fresh lemon juice over the potatoes just before serving.
· Dairy-free version: Omit the Parmesan cheese or use a high-quality vegan Parmesan. The potatoes will still be delicious, just less cheesy.
· Herb-loaded version: Use 2 tablespoons of fresh herbs (rosemary, thyme, parsley, chives) instead of dried. Add delicate herbs like parsley and chives after roasting.
· Balsamic Parmesan potatoes: Drizzle 2 tablespoons of balsamic glaze over the potatoes during the last 5 minutes of roasting. The vinegar adds sweetness and tang.
· Loaded baked potato version: Top the roasted potatoes with sour cream, crispy bacon bits, and extra chives before serving.
· Air fryer method: Parboil and rough up the potatoes as directed. Toss with oil, garlic, Parmesan, and seasonings. Air fry at 400 degrees Fahrenheit for 12 to 15 minutes, shaking the basket halfway through.

Frequently Asked Questions
Why do you parboil potatoes before roasting?
Parboiling (partially boiling) the potatoes before roasting accomplishes two things. First, it starts cooking the interior, ensuring a fluffy, tender center. Second, the parboiling process gelatinizes the starches on the potato’s surface. When you rough up the potatoes after draining, those starches create a craggy, textured exterior that becomes exceptionally crispy in the oven.
Can I use any type of potato for this recipe?
Yes, but the texture will vary. Baby Yukon Gold or red potatoes are ideal because they are waxy enough to hold their shape but still become fluffy inside. Russet potatoes produce the crispiest exterior but can fall apart if over-parboiled. If using russets, cut them into 1-inch chunks and parboil for only 6 to 7 minutes. Avoid waxy potatoes like new potatoes or fingerlings—they will not get as fluffy inside.
How do you get roasted potatoes really crispy?
The three secrets to crispy roasted potatoes are: (1) parboil with salt, (2) rough up the surfaces after draining, and (3) roast at a high temperature (425 degrees Fahrenheit or higher) on a preheated baking sheet without overcrowding. The rough, starchy surfaces create more surface area for browning, and the high heat ensures the exterior crisps before the interior overcooks.
Can I make these potatoes ahead of time for a party?
Yes. Parboil and season the potatoes, but do not roast them. Spread them on the baking sheet, cover, and refrigerate for up to 24 hours. When ready to serve, roast at 425 degrees Fahrenheit, adding 5 to 10 minutes to the cooking time since you are starting from cold. This works beautifully for holiday meals.
Why is my Parmesan burning in the oven?
Parmesan cheese can burn if exposed to high heat for too long. To prevent burning, add only half of the Parmesan before the first roasting period, then add the remaining Parmesan during the last 10 to 15 minutes of roasting. Alternatively, sprinkle the Parmesan over the potatoes only in the final 5 minutes. The cheese should be melted and golden, not dark brown or black.
Are these potatoes gluten-free?
Yes, as written. Potatoes, olive oil, garlic, Parmesan cheese, herbs, and spices are all naturally gluten-free. Always check that your spices and Parmesan are processed in a gluten-free facility if you have celiac disease or a severe sensitivity.
Can I use dried herbs instead of fresh?
Yes. This recipe is written with dried herbs for convenience and consistent results. If you prefer fresh herbs, use three times the amount of fresh herbs (3 teaspoons fresh for every 1 teaspoon dried). Add delicate fresh herbs like parsley, chives, or dill after roasting, while heartier herbs like rosemary and thyme can be added before roasting.
What is the best oil for roasting potatoes?
A high-smoke-point oil is essential for roasting at 425 degrees Fahrenheit. Avocado oil, light olive oil, grapeseed oil, and canola oil are all excellent choices. Extra virgin olive oil has a lower smoke point and can burn, but it works if you watch the potatoes carefully. Avoid butter—it burns at high heat (though a little butter added to oil is fine).
