How to Make Brown Butter Hasselback Potatoes with Caramelized Onions

Step 1: Prepare the Potatoes

1. Preheat the oven to 450°F (232°C).
2. Place the potatoes on a cutting board and lay a butter knife on each side.
3. Slice the potatoes crosswise, making cuts about ¾ of the way through. The knives will prevent you from cutting all the way through.
4. Place the sliced potatoes on a baking sheet.
5. Brush the potatoes all over, including the slices and crevices, with olive oil.
6. Sprinkle with salt and pepper, ensuring the seasoning gets into the slices.

Step 2: Roast the Potatoes

1. Roast the potatoes for 45-50 minutes, or until deeply golden brown and crispy.
2. Adjust roasting time based on potato size.

Step 3: Caramelize the Onions

1. While the potatoes are roasting, melt the butter in a skillet over medium heat.
2. Add the sliced onions and a pinch of salt.
3. Cook for 10 minutes, stirring often, until the onions are translucent.
4. Reduce the heat to medium-low and continue to cook, stirring often, until caramelized and golden brown, about 1 hour.
5. If the onions become too dry, add a splash of water.

Step 4: Make the Brown Butter

1. Once the potatoes are done, melt the butter in a skillet (you can use the same skillet as the onions, after removing them) over medium-low heat.
2. Cook, stirring occasionally, until the butter bubbles and brown bits appear on the bottom.
3. Turn off the heat and continue to stir for about 30 seconds.
4. Stir in the minced garlic.

Step 5: Assemble and Serve

1. Brush the brown garlic butter all over the roasted potatoes, including the crevices.
2. Sprinkle with chopped fresh herbs.
3. Top with the caramelized onions.
4. Serve immediately.
