A few years ago, I stumbled on the art of caramelizing onions — and it changed the way I cook forever. I used to rush the process, but once I learned the beauty of slow cooking, I understood why chefs call onions “nature’s candy.”
One night, I decided to toss those glossy, golden strands into pasta with a few leftover chicken pieces — and it turned into one of my favorite comfort meals. It’s one of those recipes that feels luxurious but is secretly so simple to make.
Kitchen Hacks
- Caramelize with patience. Keep your heat medium-low and stir often — this is where the deep flavor develops.
- Add a splash of balsamic. For extra depth, stir in a teaspoon of balsamic vinegar (use an aged balsamic vinegar for more flavor) once onions turn golden.
- Reserve pasta water. The starchy liquid helps the sauce cling perfectly to the noodles.
- Use leftover chicken. Rotisserie or grilled chicken works beautifully here, saving you time.
- Cheese tip. Always grate your parmesan fresh for the creamiest melt and richer taste.

kcalIngredients
2 tablespoons unsalted butter
2 tablespoons olive oil
3 large yellow onions, thinly sliced
3 garlic cloves, minced
1 teaspoon balsamic vinegar (optional)
1 ½ cups cooked chicken breast, sliced
12 oz spaghetti or fettuccine
½ cup grated parmesan cheese
½ cup heavy cream or milk
1 cup reserved pasta water
Salt and black pepper, to taste
Fresh parsley, for garnish
Directions
- Melt the butter together with olive oil in a large skillet over medium-low heat, then add the sliced onions, stirring to coat them well. Continue cooking slowly, stirring every few minutes, until the onions turn a deep golden brown and release their natural sweetness — this should take about 20 minutes.
- Once the onions are soft and caramelized, add the minced garlic and cook briefly until fragrant. At this point, if you want an extra layer of depth, deglaze the pan with a splash of balsamic vinegar and stir to lift any browned bits from the bottom.
- Meanwhile, bring a large pot of salted water to a boil. Add your pasta and cook it until al dente, making sure to reserve a cup of pasta water before draining. This starchy liquid will help create a velvety sauce later.
- When the onions are ready, toss in the cooked chicken and stir until it’s evenly coated with the onion mixture. The flavors will start to blend beautifully as the chicken warms through.
- Next, pour in the cream and about half of the reserved pasta water, stirring continuously until the sauce starts to thicken slightly. Gradually sprinkle in the grated parmesan, mixing well until the sauce becomes smooth and silky.
- Add the cooked pasta to the skillet and toss everything together until each strand is coated in the caramelized onion sauce. If the sauce feels too thick, slowly add more pasta water, one splash at a time, until it reaches your preferred consistency.
- Finally, taste and adjust with salt and pepper as needed. Serve the pasta hot, garnished with chopped parsley and a final dusting of parmesan for that irresistible finishing touch.
Serving Suggestions / Variations
- For a lighter twist, swap cream for milk or Greek yogurt.
