Preheat your oven to 400°F (200°C). Line a sheet pan with parchment paper or lightly grease it with olive oil.
Slice the Italian sausage into bite-sized rounds.
Wash and chop the broccoli florets into smaller pieces.
Rinse the grape tomatoes and pat them dry.
In a large mixing bowl, combine the dry gnocchi, sliced sausage, grape tomatoes, and broccoli. Drizzle with olive oil, then sprinkle with garlic powder, Italian seasoning, salt, and cracked black pepper. Toss everything together until well coated.
Evenly spread the gnocchi, sausage, and veggies on the prepared sheet pan, making sure they are in a single layer to allow even roasting.
Place the sheet pan in the preheated oven and bake for 25 minutes, stirring halfway through to ensure even cooking. The gnocchi should be crispy on the edges, the sausage cooked through, and the vegetables slightly charred.
Remove from the oven and sprinkle with freshly chopped parsley. Serve hot and enjoy!
