FAQs

Can I make caramelised onion pasta ahead of time?

While you can caramelise the onions a day or two in advance, it’s best to cook the pasta and assemble the creamy caramelised onion pasta fresh just before serving. This ensures the best texture for the pasta and the freshest taste for the sauce.

Can I make this caramelised onion pasta dairy-free?

You can certainly adapt this caramelised onion pasta to be dairy-free. Use a plant-based butter or olive oil, and substitute the heavy cream with a creamy oat milk or cashew cream. Nutritional yeast can provide a cheesy flavor in place of Parmesan.

How do I prevent the onions from burning while caramelising?

The key to perfectly caramelised onions for your caramelised onion pasta is patience and low heat. Use a heavy-bottomed pan and stir frequently, especially in the beginning. If they start to stick, add a tiny splash of water or broth to deglaze the pan and scrape up any browned bits.

• 1 tbsp Balsamic Vinegar

For the Pasta

For the Sauce

Equipment

• Large Pot
• Cutting board
• Sharp knife
• Wooden Spoon/Spatula

Method

 

Caramelise the Onions

• Heat olive oil and butter in a large skillet over medium-low heat. Add the thinly sliced onions, salt, and pepper. Toss to coat. Cook, stirring occasionally, for 35-40 minutes, or until the onions are deeply golden brown and very tender. If they start to stick, add a tablespoon of water or broth.
• Once caramelised, stir in the balsamic vinegar and cook for another 1-2 minutes until absorbed. Remove the onions from the skillet and set aside in a bowl.

Cook the Pasta

• While the onions are caramelising, bring a large pot of salted water to a rolling boil. Add the pasta and cook according to package directions until al dente. Before draining, reserve 1 cup of the starchy pasta water.

Prepare the Sauce and Assemble

• In the same skillet used for onions (no need to clean), add the minced garlic and cook over medium heat for 30 seconds until fragrant. Pour in the vegetable broth and heavy cream, scraping up any browned bits from the bottom of the pan. Bring to a gentle simmer.
• Add the cooked pasta and the caramelised onions back into the skillet with the sauce. Toss well to combine. Stir in the grated Parmesan cheese and about 1/2 cup of the reserved pasta water, adding more if needed to create a creamy sauce that coats the pasta.
• Taste and adjust seasoning with additional salt and pepper if necessary. Serve immediately, garnished with fresh chopped parsley and extra Parmesan cheese, if desired.

Notes

For an even richer flavour, a pinch of sugar can be added to the onions during the first 15 minutes of caramelisation. This recipe is also great with a handful of fresh spinach wilted into the sauce at the end.
