Begin by peeling and cutting the russet potatoes into 2-inch chunks for even cooking. Place them in a Dutch oven, covering them with cold water and adding a generous pinch of salt. Bring the water to a rolling boil over high heat, then reduce to a simmer. Cook until the potatoes are fork-tender, about 15 minutes, then drain and set aside.

In the same Dutch oven, melt a couple of tablespoons of salted butter over medium heat until it’s bubbly and fragrant. Add the chopped baby kale, seasoning with salt and pepper to taste. Sauté the kale for about 8 minutes, stirring frequently, until it becomes tender and vibrant, soaking up the buttery goodness.

Next, stir in the chopped scallions and minced garlic to the sautéed kale. Cook for an additional 2 minutes, allowing the garlic to release its fragrant aroma but be careful not to let it brown, as that can impart a bitter flavor. The mixture should be colorful and aromatic.

Pour in the half-and-half cream and gently heat the mixture for 2-3 minutes, stirring frequently. Once warmed, return the drained potatoes to the pot, and with a potato masher, mash everything together until smooth and well-combined.

Transfer the creamy Colcannon with Kale to a serving dish, using a spatula to create a slight well in the center. If desired, melt a bit more butter and drizzle it over the top for added richness. Finally, sprinkle with reserved scallions or your favorite fresh herbs.
