Step 3: Prepare the Flavor Mixture

Place the cubed potatoes into a large mixing bowl.

Pour the Italian dressing over the potatoes and toss thoroughly until every piece is coated.

Next, add:

• Minced garlic
• Parmesan cheese

Mix everything together until evenly combined.

The Parmesan will cling to the dressing-coated potatoes, helping create crispy, cheesy edges during baking.

Step 4: Arrange on the Sheet Pan

Spread the potatoes onto a large sheet pan in a single layer.

Avoid overcrowding the pan because tightly packed potatoes will steam instead of roast. Proper spacing allows hot air to circulate around the potatoes, creating a crisp texture.

If necessary, use two sheet pans instead of one crowded pan.

Step 5: Roast the Potatoes

Place the sheet pan into the preheated oven.

Roast for approximately 35 to 40 minutes, flipping the potatoes halfway through cooking.

During roasting, several things happen:

• The Italian dressing caramelizes
• The Parmesan becomes golden and crisp
• The garlic roasts and sweetens
• The potato edges become crunchy

The potatoes are ready when they are deeply golden brown and fork-tender.

Step 6: Finish and Serve

Remove the sheet pan from the oven and allow the potatoes to cool slightly for a few minutes.

For extra freshness and color, sprinkle chopped parsley over the top before serving.

Serve immediately while hot and crispy.

Tips for Perfect Roasted Potatoes

Dry the Potatoes Well

Excess moisture prevents crisping. After washing the potatoes, dry them thoroughly before adding the dressing.

Use Fresh Garlic

Fresh garlic provides stronger flavor than garlic powder and roasts beautifully in the oven.

Roast at High Heat

Lower temperatures may leave the potatoes soft instead of crispy.

Flip Halfway Through

Turning the potatoes ensures even browning on all sides.

Do Not Skip the Parmesan

The cheese creates a savory crust that makes this side dish especially addictive.

Delicious Variations

One of the best things about this recipe is how easy it is to customize.

Spicy Version

Herb Roasted Potatoes

Bacon Parmesan Potatoes

Lemon Garlic Potatoes

Squeeze fresh lemon juice over the potatoes before serving for a bright finish.
