How to Make Caramelized Onion Pasta with Chilli Oil

Sauté Those Onions : Start by heating olive oil in a pan over medium heat. Add thinly sliced onions and cook until they turn golden brown and soft, about 15-20 minutes.

Add Garlic Bliss : Once your onions are caramelized, toss in minced garlic. Sauté until aromatic—this should take about a minute—watch closely so you don’t burn it.

Toss It All Together : In your onion-garlic pan, mix in the drained pasta along with a splash of reserved water. Stir well to combine everything evenly.

Finish with Flavor : Drizzle generously with chili oil and season with salt and pepper. Toss again until every strand is coated in that glorious mixture.

Add Parmesan Magic : Finally, sprinkle freshly grated Parmesan on top before serving. It adds creaminess that beautifully balances the dish’s flavors.
