Ingredients

Scale

3 pounds Yukon Gold potatoes, peeled and quartered
3 large yellow onions, thinly sliced
6 tablespoons unsalted butter, divided
1/2 cup heavy cream, warmed
3 cloves garlic, minced
1 tablespoon fresh thyme, chopped
Sea salt to taste
Freshly cracked black pepper to taste

Instructions

Melt 3 tablespoons of butter in a large skillet over medium-low heat.
Add the sliced onions and a pinch of salt to the pan.
Cook slowly for 30 to 40 minutes, stirring occasionally until they turn a deep golden brown.
Add the minced garlic during the final two minutes of cooking to prevent burning.
Place potatoes in a large pot and cover with cold, salted water by one inch.
Bring the water to a boil and cook for 15 to 20 minutes until fork-tender.
Drain the potatoes thoroughly and return them to the warm pot to evaporate excess moisture.
Mash the potatoes using a potato ricer or hand masher.
Gently fold in the caramelized onion and garlic mixture, remaining butter, warm heavy cream, and fresh thyme.
Season with salt and pepper to taste and serve warm.

Notes

Ensure you dry the potatoes well after boiling to avoid a watery consistency. The secret to this dish is the patience taken during the 40-minute caramelization of the onions to extract their natural sugars. You can prepare the onions in advance to save time.
