First cook the poached egg (this can hold while cooking everything else). Crack an egg in a small bowl and then gently add it to a pot of simmering water. Use a spoon to carefully pull the whites of the egg together if needed. Cook the egg for about 4-5 minutes until whites are set then use a slotted spoon to remove and place on towel lined plate until ready to serve.
Then cook the pasta in boiling water until al-dente, about 7-9 minutes.
As the pasta cooks, make the rest of the dish(this will go quickly). In a skillet, drizzle with olive oil and add sliced garlic. Fry the garlic in olive oil until golden brown and crispy, then remove so it doent burn. Next, add the broccoli rabe and season with salt and pepper and red pepper flakes. Cook until softened but still bright green, about 3-4 minutes.
Add a healthy grating of Parmesan cheese and ladle the pasta into the pan with the broccoli rabe. Toss to coat and add a splash of cooking liquid if needed.
Add the garlic back in and toss to coat, adding more grated Parmesan if desired.
Finally, top with egg and an extra dusting of cracked pepper.
