How to make Creamy Onion Pasta
Ingredients:
- 12 ounces of spaghetti or your favorite pasta
- 3 large onions, thinly sliced
- 4 tablespoons of olive oil
- 1 cup of heavy cream
- 1 cup of grated Parmesan cheese
- Salt and pepper to taste
- Fresh parsley, chopped (for garnish)
Directions:
-
Cook the Pasta: Begin by boiling a large pot of salted water. Add the spaghetti and cook according to package instructions until al dente. Drain and set aside, reserving 1 cup of the pasta water.

Sauté the Onions: In a large skillet, heat the olive oil over medium heat. Add the sliced onions and sauté for about 15-20 minutes, stirring occasionally until they are soft and caramelized.
