Variation 1: Creamy Egg & Parmesan Pasta
Reduce the skillet heat to low. Add the drained pasta to the onions.
Pour the egg mixture over the pasta, tossing quickly to coat everything evenly.
Stir continuously for about 1-2 minutes until the eggs form a creamy, velvety sauce.
If needed, add a splash of reserved pasta water to loosen the texture.
Variation 2: Onion & Egg Frittata Pasta
Preheat your broiler or oven to 375°F (190°C).
Add the cooked pasta to the onions in the skillet, tossing to combine.
Pour the egg mixture evenly over the pasta and let it cook undisturbed for about 3-4 minutes.
Sprinkle mozzarella or Gruyère on top and transfer the skillet to the oven.
Bake for 5-7 minutes, or until the top is golden brown and set.
Variation 3: Baked Cheesy Egg Pasta
Preheat your oven to 375°F (190°C).
Toss the cooked pasta with the caramelized onions and egg mixture in a large bowl.
Transfer to a greased baking dish and top with breadcrumbs and extra Parmesan.
Bake for 15-20 minutes, until the top is crispy and golden brown.
