Ingredient of the Week: Walnuts

I absolutely love using walnuts in my cooking. Not only do they add a wonderful nutty flavour and crunch, but they also offer a plethora of health benefits. As a plant-based chef, I’m always looking for ingredients that are both nutritious and versatile, and these nuts definitely fit the bill.

How To Use Walnuts

Overall, I think walnuts are a fantastic ingredient to have on hand in the kitchen. They’re delicious, nutritious, and easy to source, and they can be used in so many different ways. So why not pick up a bag on your next grocery trip and start experimenting in the kitchen?

One of my favourite ways to use walnuts is to make a vegan pesto. I love toasting the walnuts in a dry skillet before blending them with fresh basil, garlic, and olive oil. It’s a simple and delicious sauce that can be used in so many ways, from pasta to pizza to grilled veggies. I also love using them as a topping for my salads. They add a great texture and flavour, and they’re a great source of protein and fibre. And when it comes to baking, walnuts are a must have ingredient in my pantry. I love adding them to my banana bread recipe or using them as a crumble topping for pies and cobblers. 

Another way I love to use them is to make walnut butter. It’s a great alternative to peanut or almond butter, and it’s incredibly easy to make. Simply blend some toasted walnuts in a food processor until they’re smooth and creamy. You can add a pinch of salt or a drizzle of honey for extra flavour, or even mix in some cinnamon or cocoa powder.

When it comes to savoury dishes, walnuts are a great addition to roasted vegetables or pasta dishes. I love tossing some with roasted brussels sprouts or adding them to a butternut squash pasta dish. They add a depth of flavour and texture that really takes the dish to the next level.

And let’s not forget about breakfast. Walnuts are a great way to add some crunch and flavour to your morning routine. I love sprinkling them over my oatmeal or yoghurt, or even adding them to my smoothies for a protein boost.
