Pasta Carbonara

100g dry linguine
1 slice of bacon, diced
1 small yellow onion, finely chopped
1 large egg yolk
1 tablespoon grated Parmesan, plus more for garnishing

4. Working quickly, add the onion, bacon, and reserved pasta water to the pasta pot. Place over low heat and cook, tossing frequently, until heated through.

5. Remove pot from heat and quickly add the yolks one at a time, stirring after each addition. Add the Parmesan and ½ teaspoon pepper and stir until the sauce thickens slightly.

6.Divide the pasta among bowls. Top with additional Parmesan and the remaining pepper.
