Prep the Pot: Place the cubed sweet potatoes and sliced sausage directly into the slow cooker.
Whisk the Sauce: In a small bowl, combine the honey, Dijon mustard, minced garlic, smoked paprika, and onion powder. Whisk until the mixture is smooth and well combined.
Toss and Coat: Pour the honey glaze over the sausage and potatoes. Use a spoon or spatula to toss everything together until every piece is evenly coated.
Season: Sprinkle with salt and a generous amount of black pepper. The pepper is essential to cut through the sweetness of the honey.
Slow Cook: Cover and cook on LOW for 5–6 hours (or HIGH for 3 hours). The potatoes should be fork-tender and the sauce should have thickened into a tacky glaze.
The Final Stir: Give the mixture one last gentle stir before serving to ensure the sausage and potatoes are swimming in those glistening, caramelized juices.
Serve: Spoon into bowls. This dish is hearty enough to stand alone but pairs beautifully with a fresh green side.
