Late Night Pasta

• 1 pound spaghetti
• 4 slices bacon, cut into 1-inch strips
• 2 tablespoons olive oil
• 2 tablespoons thinly sliced garlic
• 1 to 2 tablespoons chopped shallots
• 1/2 teaspoon crushed red pepper
• 1/2 teaspoon salt
• 1 large egg
• 1/4 to 1/2 cup grated Parmigiano-Reggiano, as desired

Bring a large heavy pot of salted water to a boil. Add the spaghetti and cook, stirring to separate the strands, until the pasta is al dente, 7 to 8 minutes for dry pasta. Drain in a colander, reserving 1/2 cup of the pasta cooking water.

Meanwhile, in a large skillet, heat the oil over medium heat. Add the bacon and cook until crisp. Add the garlic, shallots, pepper, and salt and cook, stirring, until fragrant and the garlic is soft but not brown, about 1 1/2 minutes.

Remove the pan from the heat and add the egg and reserved pasta cooking water, stirring quickly until the mixture thickens, but the egg does not scramble.

Toss together the bacon mixture and the pasta and sprinkle the cheese on top of each serving.
