Why I Love These Potatoes

Food does not need a long recipe with endless ingredients to be delicious and worthy of a special meal.

This recipe for garlic and rosemary roasted potatoes proves that simple, maybe even pantry staples for some, ingredients can create a perfect dish in under an hour.

To utilize the best of the spring, I use new potatoes. They are young potatoes that cook quickly and have the perfect creamy interior. There is no need to make a casserole. These are simply prepared with olive oil, spices, herbs, and a small amount of cornstarch to ensure they are crisp on the outside. Once roasted, they will become a favorite and soon be a recurring staple.

How to Make Rosemary Roasted Potatoes

Step 1: Prepare the potatoes – Cut the potatoes into bite-sized pieces and place them into a bowl. Douse with olive oil.

Step 2: Add flavoring – Add cornstarch, black pepper, kosher salt, paprika, onion powder, and garlic powder to the potatoes. Finely chop the rosemary and add to the bowl. Mix together, ensuring all the potatoes are evenly coated in oil and flavorings.

Step 3: Roast the potatoes – On a parchment-lined baking sheet, spread the potatoes into an even layer. Place into a 425°F oven for 25-30 minutes, until the potatoes are crispy and golden brown. Grate Parmesan cheese over the potatoes. If desired, sprinkle chopped parsley on top. Serve warm.

Recipe Tips

  • Ensure the potatoes are cut into even sizes, which will allow them the same amount of time to roast, giving the dish uniformity. The smaller the pieces are, the faster they’ll roast.
  • Using garlic powder works best for this recipe because of the high heat during roasting. Fresh garlic tends to burn at this level and length of roasting. This gives it a more bitter taste. The dried garlic powder gives the garlic taste without the bitterness.
  • If available, use the convection setting on the oven when roasting the potatoes. This turns on a fan in the back of the oven. The fan helps circulate the hot air evenly around the oven. The potatoes get a crispy exterior while being all being roasted at a similar rate.

Frequently Asked Questions

What type of potato works best? Can this be made with sweet potatoes instead?

Small new potatoes work best for this recipe. A Yukon Gold or russet potato would work, but it would need to be cut down to the correct size. A sweet potato may have an interesting flavor with the other spices in this recipe, and it would need to be sliced down to the correct size, but it would work.

Can this be made spicy?

Of course! You can add red pepper flakes or ground cayenne if you want some spice.

How long will this last after preparing?

The crispy texture of these potatoes is best when fresh. However, any leftovers should be stored in an airtight container in the refrigerator and will last for 5 to 7 days.

Garlic & Rosemary Roasted Potatoes

5 from 8 votes
A springtime blend added to potatoes creates a simple but powerful side dish. Garlic, paprika, and rosemary coat each bite with fresh flavor. Cornstarch makes the potatoes crispy, while Parmesan cheese finishes off the dish with a salty twang. This classic pairs perfectly with any meal and is great for a last-minute addition to the spread.

    I was away visiting my Son and Family over Halloween and when I returned, My New Magazine was in my Mailbox – I managed to get into my house with all the mail, my luggage, and all the other things I had taken on the trip….I threw it all aside and grabbed a much needed chocolate/coffee Latte and sat down with the new Holidays Magazine. Over the next hour I went over the latest edition page-by-page! Once again, it is a Masterpiece!! I love the addition of the shopping area and the recipes this year…ohhhh the recipes!
    Great job Kaleb and Team for putting together such an Inspirational, motivating magazine to help us kick off the Holiday Season! BRING ON ALL THE MADNESS OF THE HOLIDAYS! NOW I’m ready!

    Outstanding. Wow. I have been making “meh” roasted rosemary garlic potatoes for quite some time and decided I needed to up my game tonight. So glad I did! These were crispy outside, soft and fluffy inside and so full of flavour. My husband and son raved about them. I have some leftovers that I will heat in a frying pan tomorrow so hopefully they have some of that delightful crispy texture. Highly recommend. They’re a delight and really easy to put together.
