1-First Step: Mise en place Gather and prep everything before the stove heats up. Chop the bacon into small pieces, finely dice one small onion, and mince two garlic cloves. Measure 1 1/2 cups heavy cream and grate 1 cup fresh Parmesan. Bring a large pot of water to a boil and keep your colander within reach. Having the ingredients ready keeps the sauce from overcooking and prevents last-minute scrambling.

2-Second Step: Cook the pasta Fill the pot with cold water, place over high heat, and bring to a rolling boil. Add 1 tablespoon salt to the boiling water and toss in 12 oz dried pasta (spaghetti or any long noodle). Cook the pasta for two minutes less than the package instructions so it remains slightly firm (al dente) and finishes cooking in the sauce. Before draining, reserve 2 cups of the pasta cooking water, then drain the noodles.

3-Third Step: Crisp the bacon While the pasta cooks, heat 1/2 tablespoon olive oil in a large frying pan over medium-high heat. Add 10 strips chopped bacon (smoked preferred) and cook for 4 to 5 minutes or until crispy. Use a slotted spoon to remove the bacon and transfer it to a plate lined with paper towels. Leave the rendered bacon grease in the pan; that fat is the flavor base for your sauce.

4-Fourth Step: Build the aromatics Reduce the pan heat to medium-low. Add the 1 small finely chopped onion to the pan and sauté in the bacon grease for 3 to 4 minutes until soft and translucent. Add 2 cloves minced garlic and cook for about 30 seconds to 1 minute until fragrant. If your pan looks dry, add a splash of olive oil but avoid adding too much liquid here.

5-Fifth Step: Make the cream sauce Pour 1 1/2 cups heavy cream into the pan with the softened onion and garlic. Add 1/2 cup of the reserved pasta water now to help the sauce come together. Bring the mixture to a gentle simmer and let it reduce for about 2 minutes. Keep the heat low enough that the cream does not boil vigorously; a gentle simmer helps thicken without breaking the sauce.

6-Sixth Step: Finish the cheese sauce With the sauce warm and slightly thickened, gradually sprinkle in 1 cup freshly grated Parmesan cheese while stirring constantly. Adding the cheese slowly gives it time to melt and incorporate into the cream without clumping. If you only have store-bought grated cheese, use 1/2 cup, but freshly grated yields better texture and flavor.

7-Seventh Step: Combine pasta and sauce Add the partially cooked pasta to the pan and toss gently in the sauce. Cook for another 2 minutes while tossing, letting the pasta finish cooking and absorb the cream. If the sauce looks too thick, gradually add reserved pasta water, a few tablespoons at a time, until it reaches a silky, coating consistency. The starchy pasta water is the secret to a smooth sauce that clings to the spaghetti.

8-Final Step: Add bacon, season, and serve Stir the crispy bacon back into the pasta, taste, and adjust with salt and pepper. Remember bacon is salty, so taste before adding more salt. Plate into warm bowls and garnish with chopped fresh parsley if desired. Serve immediately while hot for the best texture and flavor.
