Caramelized Onion Mashed Potatoes
Description
Caramelized Onion Mashed Potatoes start by gently cooking sliced onions with butter, oil, salt, and thyme over medium-low heat for 20-25 minutes until deeply softened and golden brown, developing rich sweetness. Meanwhile, peeled and chunked potatoes are boiled in salted water until easily pierced with a fork, ensuring a tender, fluffy mash.
After draining and steaming briefly to remove excess moisture, the potatoes are mashed using a ricer or masher. Butter, heavy cream, Dijon mustard, and black pepper are stirred in to create a smooth and creamy base. Finally, the caramelized onions are folded through, imparting a subtle savory sweetness and herb aroma from the thyme.
This side dish pairs well with roasted meats and poultry. Its creamy texture and balanced flavors elevate traditional mashed potatoes with a gourmet touch.
