If you’ve never turned humble onions into the star of your dinner, this Caramelized Onion Pasta recipe will change your mind!

Kitchen Hacks
- Use a wide pan: It helps the onions caramelize evenly instead of steaming.
- Low and slow: Don’t rush the onions! Stir occasionally, and let them cook for at least 30 minutes for the best flavor.
- Deglaze with wine or broth: It adds depth and helps lift the fond (those tasty brown bits) from the pan.
- Add cream or cheese last: To keep the sauce silky and prevent curdling.
- Save pasta water: A splash will help bind everything together beautifully.

kcalIngredients
3 large yellow onions, thinly sliced
3 tbsp olive oil
1 tbsp unsalted butter
2 cloves garlic, minced
10 oz spaghetti or linguine
½ cup heavy cream (optional for creamy version)
¼ cup grated Parmesan cheese
1 tsp salt
½ tsp black pepper
¼ tsp chili flakes (optional)
Fresh parsley for garnish
Splash of white wine or vegetable broth for deglazing
Directions
- Start by slicing your onions thinly and evenly so they cook uniformly.
- In a large skillet, heat olive oil and butter over medium heat until melted.

- Meanwhile, boil pasta in salted water until al dente. Save ½ cup of pasta water before draining.

- Finally, season with pepper, sprinkle with chili flakes, garnish with parsley, and serve immediately.
