Cook the spaghetti (the pasta!) in a small amount of salted water.
Meanwhile, spiralize your zucchinis into spaghetti (see our article on how to make zucchini spaghetti).
In a pan, cook the bacon over low heat at first (no need to add extra fat), then increase the heat to crisp them up a bit.
Prepare the carbonara sauce: whisk together the egg yolks and Parmesan.
Ladle out some of the pasta cooking water and gradually whisk it into the sauce. The hot water will melt the Parmesan and create a creamy texture.
Two minutes before the pasta is done, add the zucchini spaghetti to the pot. Stir gently to combine.
Drain the spaghetti mixture and transfer it to a serving dish.
Pour the carbonara sauce over the spaghetti, add the bacon, and mix well. For an extra touch of flavor, drizzle with a bit of olive oil before serving. Enjoy!
