Ingredients
Scale
For the Caramelized Onions:
- 1 tablespoon olive oil
- 2 medium onions
- 1 tablespoon sugar
- 1/4 cup balsamic vinegar
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
For the Pasta:
- 8 ounces pasta
- 1/2 cup heavy cream
- 1/4 cup grated Parmesan cheese
- 1 tablespoon butter
Instructions
- Heat olive oil: Warm the olive oil in a large skillet over medium heat to prepare for sautéing the onions.
- Slice onions: Peel the onions and thinly slice them into rings or half-rings for even caramelization.
- Cook onions to soften: Add the sliced onions to the skillet and cook, stirring occasionally for about 5 minutes until they start to soften.
- Add sugar: Sprinkle sugar over the onions and stir to help enhance the caramelization process.
- Caramelize onions: Continue cooking the onions for about 10 minutes, stirring occasionally, until they develop a deep golden brown color and rich flavor.
- Deglaze with balsamic vinegar: Pour in the balsamic vinegar and stir to scrape up any browned bits from the bottom of the skillet, intensifying flavor.
- Season and simmer: Season with salt and black pepper, then let the mixture simmer for 2 minutes until slightly thickened.
- Boil water for pasta: While onions simmer, bring a large pot of salted water to a boil to cook the pasta.
- Cook pasta: Add the pasta and cook according to package instructions until al dente.
- Drain pasta: Drain the pasta, reserving about 1/2 cup of the pasta cooking water for adjusting sauce consistency.
- Add butter to skillet: Stir the butter into the caramelized onions until it melts and blends evenly.
- Add heavy cream: Pour in the heavy cream and simmer the sauce for 2-3 minutes until it thickens slightly.
- Toss pasta with sauce: Add the drained pasta to the skillet and toss well to coat each strand with the creamy caramel onion sauce.
- Adjust sauce consistency: If the sauce is too thick, add reserved pasta water one tablespoon at a time until desired consistency is reached.
- Add Parmesan cheese: Stir in grated Parmesan until melted and fully integrated into the sauce.
- Season to taste: Taste and adjust seasoning with more salt and pepper if needed for perfect flavor balance.
- Serve: Serve immediately, garnished with extra Parmesan cheese if desired, to enjoy the dish at its best.
Notes
- Use yellow or sweet onions for the best caramelization and balanced sweetness.
- Be patient when caramelizing onions; low and slow cooking delivers the richest flavor.
- Reserve pasta water as the starch helps to bind and loosen the sauce if needed.
- For a vegetarian option, ensure Parmesan cheese is made without animal rennet.
- This dish pairs well with a simple green salad or crusty bread for a complete meal.
