These Crispy Parmesan Garlic Roasted Potatoes are the perfect side dish—crunchy on the outside, fluffy on the inside, and packed with savory flavor. The secret is parboiling the potatoes and using a generous coating of Parmesan cheese that forms a golden, crackly crust.
They’re simple enough for a weeknight dinner but impressive enough for a holiday table.
The Grocery List (Ingredients)
For the Potatoes:
-
2 lbs Baby Yukon Gold or Red Potatoes (or Russet potatoes, cut into 1.5-inch chunks)
-
2 tablespoons Salt (for the boiling water)
-
¼ cup Olive Oil (or melted butter for extra richness)
-
4 cloves Garlic, minced (or 1 tablespoon garlic paste)
-
½ cup Freshly Grated Parmesan Cheese (the kind in the green can won’t melt the same way—freshly grated is a must for the crust)
-
1 teaspoon Dried Oregano or Italian Seasoning
-
½ teaspoon Black Pepper
-
Fresh Parsley, chopped (for garnish)
The Step-by-Step Method
Step 1: Preheat and Prep
-
Preheat your oven to 400°F (200°C) .
-
If using larger potatoes, cut them into uniform 1.5-inch pieces. If using baby potatoes, you can leave them whole or cut them in half.
Step 2: Parboil the Potatoes (The Secret to Fluffy Insides)
-
Place the potatoes in a large pot and cover with cold water by about 1 inch.
-
Add 2 tablespoons of salt to the water (this seasons the potatoes from the inside out).
-
Bring to a boil and cook for 7-10 minutes, until the potatoes are just fork-tender (you should be able to pierce them with a knife, but they shouldn’t fall apart).
-
Crucial Step: Drain the potatoes and let them sit in the colander for 2-3 minutes to steam dry. Excess moisture is the enemy of crispiness.
Step 3: Season the Potatoes
-
In a large bowl, whisk together the olive oil, minced garlic, oregano, and black pepper.
-
Add the parboiled potatoes to the bowl and toss gently to coat.
-
Sprinkle in the grated Parmesan cheese and toss again until the potatoes are evenly coated. The cheese will stick to the rough, starchy surface of the potatoes.
Step 4: Arrange on the Pan
-
Line a large baking sheet with parchment paper (for easy cleanup) or use a non-stick sheet.
-
Spread the potatoes in a single, even layer, making sure they aren’t crowded. Give them space! If they’re crowded, they’ll steam instead of roast.
-
Reserve any extra cheese mixture left in the bowl to sprinkle on top later.
Step 5: Roast to Perfection
-
Roast for 20 minutes.
-
Remove the pan from the oven. Use a spatula to flip the potatoes. Sprinkle any reserved cheesy bits over the top.
-
Return to the oven and roast for another 15-20 minutes, until the potatoes are deep golden brown and the Parmesan has formed a crispy, crackly crust.
Step 6: Garnish and Serve
-
Sprinkle with fresh chopped parsley for a pop of color.
-
Serve immediately—these are best straight from the oven while the crust is at its crispiest.
Pro-Tips for Success
-
The Parmesan Matters: Pre-shredded or powdered Parmesan won’t create the same crust because it contains anti-caking agents. Grate it fresh from a block for the best results.
-
Don’t Skip the Parboil: This step ensures the insides are perfectly fluffy while the outsides get extra crispy.
-
Space is Key: A crowded pan traps steam. Use a large enough baking sheet or use two sheets if needed.
-
Extra Garlic Lover’s Tip: For even more garlic flavor, add another 2 cloves of minced garlic to the potatoes halfway through roasting (add it when you flip them, so it doesn’t burn).
