Ingredients
Scale
Pasta
- 200g dried pasta (spaghetti or linguine)
Caramelized Onions
- 2 large yellow onions, thinly sliced
- 2 tablespoons unsalted butter
Chili Oil
- 2 tablespoons chili oil (adjust to taste)
Instructions
- Prepare the onions: Peel and thinly slice the onions to ensure even caramelization.
- Caramelize the onions: Heat butter in a large skillet over medium-low heat. Add the sliced onions and cook slowly, stirring occasionally, until they turn golden brown and soft, about 30-40 minutes. This slow cooking brings out the onions’ natural sweetness.
- Cook the pasta: While the onions caramelize, bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain the pasta, reserving a small amount of pasta water.
- Toss with chili oil: Return the pasta to the pot or a large bowl. Add the caramelized onions and chili oil, tossing gently to combine. Use a little reserved pasta water if needed to loosen the sauce and help everything coat the pasta evenly.
- Serve: Plate the pasta immediately while warm, optionally garnishing with fresh herbs or grated cheese if desired.
Notes
- Slow caramelization of onions is key to developing deep flavor; don’t rush or use high heat.
- Adjust the amount of chili oil based on your preferred spice level.
- You can add grated Parmesan or fresh basil for extra flavor.
- Use good quality chili oil for the best taste.
- If unavailable, you can make your own chili oil by infusing olive oil with red pepper flakes.
