Roasted garlic mashed potatoes are a hearty, decadent side, and these rival the version found at any steakhouse or other restaurant.
Roast the garlic. Preheat the oven to 400 degrees F. Slice about ¼ inch off of the top of the head of garlic. Place the head of garlic in the center of a square piece of foil. You can line with parchment, if you have concerns about aluminum exposure. Drizzle the olive oil over the garlic and sprinkle it with salt and pepper. Wrap the foil around the garlic and close it up. Roast it in the oven until soft, about 40 minutes. This may be longer for larger heads of garlic, FYI. Once it is done, carefully remove it and carefully open it up. Hint: watch out for steam! Make ahead of time (recommended), or set aside to cool while you do the other steps below.
Drain the potatoes. Drain the water from the potatoes and return them to the pot you cooked them in.
Taste to check the flavor. If you want to, add any additional salt, pepper, herbs or butter.
Serve. These potatoes are best served nice and hot with your favorite main dish like grilled chicken, steak or fish.
To roast the garlic quicker you can do it in the air fryer. To roast the garlic in the air fryer, preheat the air fryer to 380 degrees F. Cut about ¼ inch off of the top of the garlic head. Place the head of garlic in the center of a square piece of foil. Drizzle the olive oil over the garlic and sprinkle it with salt and pepper. Wrap the foil around the garlic and close it up. Place the garlic into the air fryer basket and roast for 20-30 minutes. Remove and let cool for 4-5 minute before opening.
