Creating Pasta with Caramelized Onions is simple if you follow these clear steps:

1. Cook the Pasta: Begin by boiling water in a large pot. Add a generous pinch of salt and cook the pasta according to package instructions until al dente. Drain and set aside, reserving about ½ cup of the pasta water.

1. Caramelize the Onions: In a large skillet, heat olive oil and butter over medium heat. Add the sliced onions, stirring gently to coat. Sprinkle with a pinch of salt.

1. Cook Slowly: Reduce the heat to low and cook the onions, stirring occasionally, until they are golden brown and caramelized, about 15-20 minutes. If they begin to stick or burn, add a splash of water to the pan.

1. Add Garlic (Optional): If you like garlic, add minced garlic to the onions in the last 2-3 minutes of cooking, stirring until fragrant.

1. Combine: Once the onions are caramelized, add the cooked pasta to the skillet. Toss gently to combine. If the pasta seems dry, add a bit of the reserved pasta water until desired consistency is reached.

1. Season: Sprinkle with freshly ground black pepper and adjust seasoning with salt as needed.

1. Add Cheese: Remove the skillet from heat, then stir in the grated Parmesan cheese until well blended.

1. Garnish: Serve immediately, garnished with chopped parsley and, if desired, crushed red pepper flakes for added heat.

1. Enjoy: Dig in and savor the incredible flavors!
