Slowly simmering kale with onions and garlic is a great way to serve this nutritious green. To make a more substantial dish, we've added bacon and chunks of butternut squash, which adds smoky flavor and sweetness to the braise. Serve with warm crusty bread for a satisfying supper.
Heat a large skillet over medium heat; when hot, add the oil and bacon. Cook, stirring frequently, until the bacon is crisp. Transfer the bacon to paper towels to drain. Add the onion to the skillet with the bacon fat and cook, stirring occasionally, until the onion begins to soften, about 5 minutes. Add the garlic and pepper flakes, and cook, stirring frequently, for 2 minutes.
Add the butternut and broth to the skillet and cook, covered, for 5 minutes. Add the kale, cover and cook until the butternut and kale are tender, 10 to 15 minutes, adding more broth if needed.
Stir in the bacon and parsley and season with salt and pepper to taste. Serve hot.
