Steps
1. Cook the pasta according to the package instructions until al dente. Drain and set aside.
2. In a large skillet, melt the butter over medium heat. Add the sliced onions and sauté until golden brown and caramelized, about 10 minutes.
3. In a separate bowl, whisk together the beaten eggs, grated cheese, salt, and pepper.
4. Add the cooked pasta to the skillet with the caramelized onions. Pour the egg mixture over the pasta and quickly toss to combine, allowing the residual heat to cook the eggs.
5. Continue tossing until the eggs are fully cooked and the cheese has melted.
6. Remove from heat and serve hot. Enjoy!
