Description
Caramelized Onion Pasta with Chilli Oil is a rich, sweet, and spicy dish that brings gourmet flavors to your table with minimal ingredients. Sweet golden onions melt into a jammy sauce that coats each strand of pasta, while chili oil adds a bold finish. It’s perfect for cozy dinners or a meatless main course with attitude.
Ingredients
12 oz spaghetti or linguine
3 large yellow onions, thinly sliced
2 tablespoons olive oil
2 tablespoons butter
2 to 3 tablespoons chili oil (adjust to taste)
1 teaspoon salt (or to taste)
2 tablespoons chopped fresh parsley (optional)
¼ cup grated Parmesan (optional)
Instructions
1. Slice the onions very thin. In a large skillet over medium-low heat, add olive oil and butter. Once melted, stir in the onions and cook slowly for 30–40 minutes, stirring occasionally, until deeply golden and jammy.
2. While onions cook, bring a large pot of salted water to a boil. Add pasta and cook until al dente. Reserve 1 cup of pasta water, then drain.
3. Add cooked pasta to the pan with caramelized onions. Toss well, adding reserved pasta water as needed to loosen and create a glossy sauce.
4. Turn off the heat and drizzle chili oil generously over the pasta. Stir to combine. Taste and adjust salt or chili level.
5. Serve hot with optional parsley and grated Parmesan on top.
Notes
For best flavor, don’t rush the caramelization—low and slow is the key to sweet, golden onions.
Adjust chili oil gradually and taste as you go to find your perfect heat level.
Reheat leftovers gently with a splash of water or more chili oil to bring back the saucy texture.
