Set a large saucepan filled with water over high heat. Bring to a boil and add the fettuccine noodles to cook to al dente, leaving a bit of a bite to them.
8 ounces dried fettuccine noodles
In a small bowl, beat the egg yolks and white together until well combined. Add the grated cheese and mix completely. Set aside.
3 egg yolks, 2 ounces grated Parmesan cheese, 1 egg
While the noodles cook, in a large saute pan, add the bacon and cook down until crispy. Drain all but 2 TB fat from the pan.
8 ounces applewood smoked bacon
To the bacon, add the shredded brussels sprouts and cook until wilted, about 5 minutes. Remove from the pan and set aside. Put the pan back on the stove.
25-30 fresh brussels sprouts
Drain the cooked noodles, reserving approximately 1 cup of pasta water. Add 1/2 cup of pasta water to the pan. Bring to a boil, about 2 minutes. Add the cooked noodles to the pan. Turn off the heat.
To the bowl of eggs and cheese, add 1/3 cup of the hot pasta water, stirring vigorously to ensure the eggs do not scramble. Pour the egg mixture over the hot pasta. Toss thoroughly to cook the eggs. Add a little extra pasta water if desired to give it as creamy a consistency as you prefer.
Add the brussels sprout/bacon mixture and toss with the pasta and add the pepper and any salt to taste. Serve immediately.
1 tsp coarse ground black pepper, salt
