Preheat your oven to 400°F (200°C).

Peel and dice the sweet potatoes into bite-sized pieces for even cooking.

In a small saucepan over low heat, melt the unsalted butter and mix in the minced garlic until fragrant. Remove from heat.

In a large mixing bowl, combine the diced sweet potatoes with the garlic butter, kosher salt, and black pepper. Toss to coat evenly.

Spread the mixture on a baking sheet lined with parchment paper.

Roast in the preheated oven for 25-30 minutes or until fork-tender and golden brown, stirring halfway through.

Serve warm, optionally garnished with fresh herbs.
