🧅 HOW TO MAKE CARAMELIZED ONIONS
The secret to get a deep and bold flavor lies in how far the onions are caramelized, you want them to be brown, not just golden brown.
First, melt oil + vegan butter in a skillet. Butter adds flavor and oil prevent it from burning.
Once melted, add thinly sliced onions and sauté for about 5 minutes, or until golden brown. Next, add salt and a teaspoon of sugar to help with the caramelization. Sauté for another 6-8 minutes, or until your onions turn brown.
Keep an eye on them to make sure they don’t burn, but do not stir too often to allow a nice caramelization.
Finally, deglaze the skillet with a couple of tablespoons of water to release the small particles stuck on the skillet, this will help extract even more flavor!
Add cooked pasta to the skillet and pour in the cashew cream. We went with our Homemade Fermented Cashew Cream for this recipe, but feel free to use store-bought plant-based cream if you want to save time.
If making your own cashew cream, make sure you prepare the liquid version (there is a spreadable and a liquid version in the recipe). Otherwise, dilute the cashew cream with some water until you get a pourable consistency.
💬 FAQ
- Can I use shallots instead of onions? Definitely! You can replace the onions with 6 small shallots.
- What can I use to substitute the fermented cashew cream? You can use your favorite store-bought plant-based cream, like oat or soy cream. We do not recommend using coconut cream for this recipe, the flavor would be overpowering.
- Which type of pasta works best for this recipe? Linguine, spaghetti, or tagliatelle are great for this recipe, but almost any pasta will work!
- How can I reheat this pasta? Yes, reheat gently in a skillet over small-medium heat. You may have to add a couple of tablespoons of water if the cream has thickened too much.
This caramelized onion pasta is perfect for a chilly evening, it has that stick-to-your-ribs factor, it’s easy to make, and packed with flavor!

Creamy Caramelized Onion Pasta
Ingredients
- 1 tbsp oil
- 1 tbsp butter
- 2 large onions thinly sliced
- 1/4 tsp salt
- 1 tsp sugar
- 1 cup fermented cashew cream* (add 1/4 tsp of salt if your cream is not salted)
- 1 tbsp nutritional yeast
- 4.5 ounces dry fettuccine pasta
Instructions
- Heat the oil and butter in a large non-stick skillet over medium heat. Once the butter has melted, add the sliced onions and add a pinch of salt. Sauté for 5-6 minutes, stirring regularly, until it starts to get a golden brown color.
- Add the 1/4 tsp of salt, and the sugar, and sauté for another 6-8 minutes, or until onions turn brown. Keep an eye on it and stir regularly, you don't want to burn the onions, but they should be caramelized. Once onions are done, deglaze the skillet with 2 tablespoons of water, and remove from heat. Set aside.
- Bring a large pot of salted water to a boil and cook the pasta according to the package instructions. Drain and transfer the cooked pasta to the skillet with the caramelized onions.
- Pour in the fermented cashew cream, nutritional yeast, and stir to coat. Cook for 3-5 minutes over medium heat, stirring frequently to coat the pasta with the sauce and the caramelized onions. If the sauce appears too thick, dilute with some water. Taste and adjust saltiness to taste.
- Serve hot, topped with fresh cilantro or parsley, and ground black pepper! This pasta is best served immediately, but will keep for up to 2 days in the refrigerator.

Super yummy and super easy.
But way too much calories for a daily meal 🙁
Thanks for your feedback and rating! 🙂 Glad you liked this recipe!
Regarding the calories, it can be made lighter very easily. Omit the oil and replace the cashew cream with soy or almond cream for example 😉
