Our healthy spaghetti carbonara recipe is lower in calories and fat than a traditional spaghetti carbonara recipe, plus it boasts 9 more grams of fiber per serving from whole-wheat pasta. For the best flavor, use Parmigiano-Reggiano cheese. The eggs in the sauce are not fully cooked; if you’re concerned about consuming undercooked eggs, use pasteurized-in-the-shell eggs in this spaghetti carbonara recipe.
