Grandma's golden egg tagliatelle dressed in simple butter and Parmigiano is Italian heritage cooking. A protein-rich mediterranean pasta that's fresh, comforting, and a family Sunday tradition.
On a clean surface, mound the flour and make a well in the center. Crack the eggs into the well, add a pinch of salt, and gently beat with a fork, gradually mixing in flour from the edges.
Knead the dough with your hands for 8–10 minutes until smooth and elastic. Cover with plastic wrap and rest at room temperature for 30 minutes to relax the gluten.
Divide the dough into four pieces. Roll out each piece with a rolling pin or pasta machine to about 1/16-inch thickness. Dust lightly with flour to prevent sticking.
Cut the sheets into tagliatelle strips about 1/4 inch wide. Toss the strips gently in flour to keep them separate.
Bring a large pot of salted water to a rolling boil. Add the tagliatelle, stir to prevent sticking, and cook for 2–3 minutes until al dente. Reserve 1/2 cup pasta water.
Meanwhile, melt the butter in a large skillet over medium-low heat. Add drained tagliatelle and toss, adding reserved pasta water as needed to create a silky sauce. Sprinkle grated Parmigiano and season with black pepper, tossing again until cheese melts and noodles are coated.
Serve immediately with extra Parmigiano and a twist of black pepper.
