This caramelized onion carbonara recipe is a vegetarian take on the Roman classic. While there is no guanciale in this dish, smoked shoyu adds a great meaty flavor.

Ingredients

  • 1 tablespoon butter
  • 1 tablespoon extra virgin olive oil
  • 2 yellow onions (peeled and diced)
  • 2 teaspoons sugar
  • 16 ounces spaghetti, rigatoni, or bucatini
  • 1–2 tablespoons smoked shoyu (more to taste if desired)
  • 4 egg yolks
  • 2 eggs
  • ⅓ cup freshly grated parmesan (plus more for serving)
  • Freshly grated black pepper
  • Salt

Directions

  1. 1

    In a wide sauté pan, heat the butter and extra virgin olive oil over medium heat until the butter is frothy and bubbly. Add the diced onion and cook, stirring regularly, until the onions deepen in color. Adjust the heat as necessary to prevent it from burning. About 15 minutes in, add the sugar and smoked shoyu and continue cooking the onions for an additional 15–20 minutes until fully caramelized and deep, golden brown. Season with salt. Turn off the heat.

  2. 2

    Bring a large pot of salted water to a boil. Add the pasta and cook until 1–2 minutes under al dente. Scoop out 1½ cups of pasta cooking water and drain the pasta. Note: depending on how you time it, you may be ready to cook the eggs right as the pasta finishes cooking, in which case, you can just use tongs to transfer the pasta straight from the water to the pot of caramelized onions. If you aren't ready, just drain the pasta first!

  3. 3

    In a large bowl, combine the egg yolks, eggs, parmesan, and ground black pepper to taste. Whisk for 3–5 minutes until smooth and creamy. Set aside.

  4. 4

    Whisking constantly, pour half of the pasta cooking water into the bowl of eggs to temper the egg mixture.

  5. 5

    Immediately serve the carbonara in shallow pasta bowls and garnish with more parmesan and black pepper. Enjoy!
