Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel the sweet potato and cut it into uniform half-inch cubes to ensure they roast evenly.
Slice the beef sausage into half-inch thick rounds.
In a large mixing bowl, combine the sweet potato cubes and sausage rounds with avocado oil, sea salt, black pepper, garlic powder, and smoked paprika.
Toss the ingredients thoroughly until everything is well-coated in the oil and spices.
Spread the mixture in a single layer on the prepared sheet pan, ensuring pieces are not overcrowded.
Roast for 20 to 25 minutes, tossing halfway through, until the sweet potatoes are fork-tender and the sausage is beautifully browned.
Remove from the oven and serve immediately, topped with fresh slices of creamy avocado.
