Caramelized Onion Pasta
Caramelized Onion Pasta
Ingredients
- 4 onions, large, thinly sliced
- 1/2 cup extra virgin olive oil
- 4 tablespoons butter
- 3 egg yolks
- 1 cup water
- 3/4 cup Parmesan cheese, grated
- 1/2 teaspoon salt, or as needed
- 1/4 teaspoon black pepper, freshly ground, or as needed
- 1 pound spaghetti, cooked al dente
- 2 tablespoons fresh parsley, chopped, for garnish (optional)
Instructions
- 1
Begin by caramelizing the onions. Heat a large, heavy-bottomed pan over medium heat. Add the butter and allow it to melt completely. Add the thinly sliced onions to the pan. Cook, stirring frequently, for approximately 40 minutes, or until the onions are deeply golden brown and caramelized. If the onions start to stick, add a tablespoon of water to deglaze the pan. Once caramelized, remove the onions from the pan and set aside.

While the onions are caramelizing, bring a large pot of salted water to a rolling boil. Add the spaghetti and cook according to package directions until al dente.

Prepare the sauce. In a blender, combine the caramelized onions, extra virgin olive oil, egg yolks, grated Parmesan cheese, salt, and black pepper. Blend until the mixture is smooth. Gradually add the water in small increments while blending, until the sauce reaches your desired consistency. Be careful not to add all the water at once, as you want a creamy sauce, not a runny one.

Once the spaghetti is cooked, use tongs to transfer it directly from the pot into the large pan (the same pan used for caramelizing onions, no need to clean it). Add the prepared caramelized onion sauce to the pan with the spaghetti. Toss thoroughly to ensure the pasta is evenly coated with the sauce.

Place the pan with the pasta and sauce over low heat. Warm for about 1 minute, tossing gently, just until the sauce is heated through and coats the pasta beautifully. Do not overheat, as the egg yolks can scramble.

Remove from heat and serve immediately. Garnish with fresh chopped parsley, if desired.
