Roasted Garlic and Rosemary Potatoes: Hearty Delicious Side Dish

Everyone should have a good Roasted Garlic and Rosemary Potatoes recipe in their arsenal whether they’re following a strict keto diet or not. Potatoes are a staple in many households and for good reason. They’re versatile, filling, and can be prepared in a variety of ways.

One of my favorite ways to prepare potatoes is by roasting them with rosemary and garlic. The combination of these flavors creates a delicious and aromatic side dish that pairs well with a variety of main courses.

For this recipe, I recommend using waxy potatoes, such as red potatoes or new potatoes. These types of potatoes hold their shape well when cooked, making them perfect for cutting into wedges.

Roasted Potatoes

Roasted potatoes are a classic side dish that has been enjoyed for centuries. The addition of rosemary and garlic takes this dish to the next level, adding a depth of flavor that is sure to impress.

Potatoes are one of the highest dietary sources of potassium. This mineral helps to maintain healthy blood pressure levels, supports the function of the kidneys and heart, and is essential for muscle and nerve function.

Potatoes are also a good source of vitamin C. This nutrient is important for maintaining a healthy immune system, collagen production, and iron absorption.

Potatoes are a good source of vitamin B6. This vitamin helps the body to produce red blood cells and maintain a healthy nervous system. Pair this dish with my Stuffed Beef Tenderloin recipe or delicious pecan-crusted Pork Chops.

Potatoes, especially when eaten with the skin, are a good source of fiber. Fiber is essential for maintaining healthy digestion and may help to lower cholesterol levels.

Potatoes are a good source of carbohydrates, which are the body’s main source of energy. They are also relatively low in calories and fat. Of course, some of us are now shying away from carbohydrates as a source of energy so read on for great low-carb potato substitutions below.

It is important to note that the nutritional value of potatoes can vary depending on how they are prepared. French fries and potato chips, for example, are high in fat and salt and should be consumed in moderation. On the other hand, baked or boiled potatoes with the skin on are a healthy and nutritious food choice.

Low-Carb Potato Substitutions

If you’re looking to make the dish low-carb, there are a few alternatives to potatoes that you can use:

  1. Cauliflower: Cauliflower can be used as a substitute for potatoes in many dishes, including this one. Simply chop the cauliflower into florets and roast them with the rosemary and garlic as directed in the recipe. Try my keto Cauliflower Mash recipe that my family loves.
  2. Turnips: Turnips can be used in place of potatoes and have a similar texture when roasted. They are also low in carbs and high in fiber.
  3. Radishes: Radishes are a great low-carb alternative to potatoes. They can be sliced and roasted in the same way as potatoes and have a similar texture and slightly spicy flavor.
  4. Zucchini: Another option is to use zucchini. Cut it into wedges and roast it with rosemary, garlic, and olive oil. Make sure to try my crispy-baked parmesan Zucchini Fries too!
  5. Eggplant: Eggplant can be cut into wedges and roasted in place of potatoes, it will give a similar texture and absorb the flavors of the rosemary and garlic perfectly.
  6. Celery Root: Celery root is a great low-carb and keto-friendly alternative to potatoes. It can be cut into wedges and roasted with rosemary and garlic as directed in the recipe.

Keep in mind that these substitutes may have slightly different cooking times, so it’s important to keep an eye on them while they’re in the oven to ensure they’re cooked to your liking.

Airfryer Roasted Potatoes

Cooking these roasted rosemary garlic potatoes in an air fryer can add a whole new level of ease and convenience to the recipe. An air fryer is a kitchen appliance that uses hot air to cook food, resulting in crispy and evenly cooked dishes.

One of the main benefits of using an air fryer is that it requires less oil than traditional deep frying, making it a healthier cooking method. Additionally, the compact size of an air fryer makes it easy to use in small kitchens or for those who have limited counter space.

When preparing these potatoes in an air fryer, be sure to toss them well with the olive oil and seasonings, and spread them out in a single layer in the basket. Cooking time may vary depending on the size and type of your air fryer, so it’s important to keep an eye on them and check for doneness.

Overall, using an air fryer to make this recipe can save you time and effort while still delivering delicious and crispy results. It’s a great option for those who are looking for a convenient and healthier way to prepare their meals.

  • 2 lbs. small multi-colored waxy potatoes cut into equal, bite-sized pieces
  • 2 tbsp extra virgin olive oil
  • 2 tsp dried rosemary
  • ½ tbsp garlic powder
  • Sea salt and black pepper to taste
  • Freshly shaved Parmesan cheese to serve
  • Sprigs of fresh rosemary for garnish


  • Turn on the air fryer and select the “Air Crisp” function. Set the temperature to 400°F and adjust the timer to 18 minutes. Press “Start” to pre-heat the unit.
  • While the unit pre-heats, combine the potatoes, olive oil, dried rosemary, and garlic powder in a large bowl. Add salt and black pepper, to taste, and toss to combine.
  • When the air fryer beeps and flashes “Add Food,” pour the seasoned potatoes into the basket and spread them into an even layer without overcrowding. Close the lid to start air frying.
  • After 9 minutes, lift the lid and carefully turn the potatoes with a plastic spatula so they brown evenly, making sure they are still in a single, even layer. Close the lid and continue air frying until cook time is complete.  
  • Transfer potatoes to a serving bowl or platter and top with freshly grated Parmesan cheese, if desired. Garnish with sprigs of fresh rosemary and serve immediately. Enjoy!
