Heat oven to 400 degrees and line a large baking sheet with parchment paper
Wash and trim the ends of the Brussels Sprouts and cut in half vertically
Toss the Brussels Sprouts and frozen gnocchi with olive oil, salt and pepper and place on the baking sheet. Spread evenly and separate so the gnocchi and sprouts are not touching and place the sprouts cut side down, lying flat.
Bake for 15 minutes, toss and flip the sprouts and bake for another 5 minutes
Add the cherry tomatoes, pour over the heavy cream and bake for another 5 minutes
Remove from the oven, add fresh basil and Parmesan and pour the entire contents, including any cooking liquid, into a serving bowl. Top with additional Parmesan and fresh basil and dried chili if using
