Step 1

Bring a large pot of salted water to a boil. Add the pasta and cook until al dente, about 3 minutes. Reserve 1/2 cup pasta water. Drain, and set aside.

Step 2

Whisk together the eggs and cheese in a bowl. Cook the bacon in a large, deep skillet over medium-high heat until browned and crisp, about 8 minutes. Remove the bacon from the skillet to paper towels to drain, then chop the bacon. Reserve 2 tablespoons bacon drippings in the skillet and discard the rest. Add the garlic and peas to the skillet and cook, stirring constantly and scraping the browned bits from the bottom of the skillet, until the garlic is fragrant and the peas are warmed through, about 1 minute.

Step 3

Add the bacon and pasta to the skillet and heat over medium heat until hot, about 2 minutes. Reduce the heat to low. Working quickly, add the egg mixture to the pasta and toss with tongs until the pasta is coated in the sauce. Gradually add a little pasta water at a time to the pasta until a creamy, saucy consistency is reached. Season with salt and pepper and sprinkle each serving with parsley and more cheese.

Step 4

Combine the eggs, flour, olive oil, salt and 1 tablespoon water in the bowl of a food processor. Pulse until a dough forms, about 10 seconds. Remove the dough from the food processor to a lightly floured surface. Knead the dough until smooth and elastic, 4 to 5 minutes. Shape the dough into a ball; wrap with plastic and rest at room temperature for 30 minutes.

Step 5

Cut the dough in half and keep one half refrigerated. Cut the remaining half into two equal pieces. (Make sure to keep the unused dough pieces covered.)

Step 6

Working with one piece at a time, roll the dough with a rolling pin as thin as possible (but still thick enough to be lifted off the counter without breaking, about a 10-by-16- inch rectangle; the dough should be paper-thin, but you shouldn’t be able to see through it.)

Step 7

Dust each dough sheet with flour. Fold the dough in half (using the short ends) and dust the top with flour. Repeat twice more, dusting with flour between each layer to create a stack. Use a sharp knife to cut the dough into thin strips (1/4-inch wide).

Step 8

Separate the noodles into “nests” and let dry on a lightly floured surface, about 1 hour. Repeat the process with the remaining dough piece, then with the remaining refrigerated dough.
