Caramelized Onion Pasta with Chili Oil

Ingredients

  • 2 large yellow onions, thinly sliced

  • 2 tablespoons olive oil

  • Salt, to taste

  • 1 tablespoon balsamic vinegar

  • 8 oz pasta (spaghetti or linguine works great)

  • 1–2 tablespoons NM Chili Oil (adjust to taste)

  • 1/4 cup reserved pasta water

  • Fresh parsley, chopped (optional)

  • Parmesan or nutritional yeast (optional, for garnish)

Steps

  1. Caramelize the onions:
    Heat olive oil in a large skillet over medium-low heat. Add sliced onions and a pinch of salt. Cook low and slow, stirring occasionally, for about 30–40 minutes until deeply golden and jammy. Don’t rush it — this is where the magic happens.

  2. Deglaze & finish the onions:
    Once caramelized, stir in the balsamic vinegar to deglaze the pan and bring a little tang to balance the sweetness.

  3. Cook the pasta:
    Boil pasta according to package instructions. Reserve 1/4 cup of pasta water before draining.

  4. Combine it all:
    Add drained pasta to the caramelized onions. Toss in reserved pasta water and NM Chili Oil. Stir until everything’s glossy and well coated. Adjust salt if needed.

  5. Serve:
    Plate it up, then top with chopped parsley and a sprinkle of parmesan or nutritional yeast if desired. Extra drizzle of NM Chili Oil? Always a good idea.

Pro Tip

The key is patience with the onions — let them do their thing. Pair with a crisp white wine or sparkling water with lemon.
