Ingredients
Caramelized onions
- 1 tablespoon olive oil
- 3 yellow onions, large, sliced
- 1/4 teaspoon salt
- 1 tablespoon balsamic vinegar
Creamy pasta sauce
- 1 tablespoon olive oil
- 10 oz mushrooms, sliced (I used button mushrooms)
- 6 oz spinach
- 1 cup half-and-half
- 1 cup Parmesan cheese, shredded
- 1/4 teaspoon salt
Pasta
- 8 oz farfalle pasta
Instructions
How to caramelize onions:
- Heat 1 tablespoon olive oil on medium-high heat in a large skillet. Add sliced onions and cook on high heat for about 10 minutes, constantly stirring with the spatula.
- The onions should start to brown, but without burning.
- Reduce heat to medium and continue cooking onions for 10 more minutes, continuing to stir, as onions brown even more without burning. At this point add a pinch of salt over onions.
- Continue cooking for 10 more minutes on medium or low heat, stirring occasionally to make sure onions don’t stick to the bottom of the pan or burn.
- In total, you should have cooked onions for 30 minutes.
- Remove the skillet from heat and sprinkle the onions with a small amount of balsamic vinegar to deglaze the pan.
- Using a spatula, stir the onions, scraping the bottom of the pan and coating onions with a pinch of balsamic vinegar you just added. Remove caramelized onions to a plate.
How to cook mushrooms and spinach:
- Heat 1 tablespoon olive oil in the same skillet on medium heat. Add sliced mushrooms. Sprinkle with a pinch of salt.
- Cook mushrooms for about 5 minutes, occasionally stirring, until mushrooms are soft.
- Add fresh spinach to the skillet and stir on low heat just until spinach starts to wilt.
How to make creamy pasta sauce:
- Add half-and-half to the mushroom and spinach mixture and bring to a quick boil. Immediately reduce to simmer.
- Add 2/3 cup of shredded Parmesan cheese and 1/4 teaspoon salt. Keep stirring while the sauce simmers until the cheese melts.
- Add caramelized onions back to the skillet with the pasta sauce.
Cook pasta:
- Cook pasta according to package instructions. Drain.
- Add cooked and drained farfalle pasta to the creamy sauce. Stir on low heat for a couple of minutes to reheat.
- If the sauce is too thick, add a small amount of half-and-half to thin it out. If it is too thin, add a small amount of shredded Parmesan cheese, and stir it in, while the sauce simmers.
- Serve with more shredded parmesan cheese sprinkled on top.
