Set the Ninja Woodfire to 350°F (177°C) with smoke enabled. Cook the sausages for about 15 minutes, or until the center reaches 160°F (71°C) for pork. Use internal temperature to determine doneness.
Melt the butter and cook the minced garlic until fragrant. Add the tomato paste and cook, stirring, until caramelized.
Add the tomatoes, 1 tablespoon kosher salt and 1 tablespoon granulated onion. Simmer the sauce, then stir in the heavy cream and Parmesan.
Cook your favorite pasta and reserve ½ cup pasta water before draining.
Slice the cooked sausage and combine with the sauce. Stir in the reserved pasta water to loosen the sauce.
Add the basil near the end. Taste before adding more seasoning. If desired, add up to 1 tablespoon more granulated onion and up to 1 tablespoon more kosher salt gradually. The extra salt is optional and may not be needed.
Serve with your favorite pasta.
