Step 1

Place raw red potato cubes in a large steamer basket over a large pot of boiling water. Cover and steam until very tender, 25 to 30 minutes.

Step 2

When potatoes are nearly tender, melt butter in a small saucepan. Add garlic; cook and stir until fragrant, about 1 minute. Add salt and olive oil; stir until just heated through. Remove from heat.

Step 3

Transfer tender potatoes to a large bowl. Pour olive oil mixture over and mash with a potato masher to desired consistency. Garnish with chives if desired and serve.
