Festive Walnut, Caramelised Onion and Squash Galette with Walnut Pesto Dressing

A delicious savoury galette with squash and sweet caramelised onions, which pairs incredibly well with the earthy walnuts in the base and fresh pesto. Yum!

This lovely savoury galette is the perfect way to get Christmas cracked, as it makes a great centrepiece.

The squash and sweet caramelised onions pair incredibly well with the earthy California walnuts in the base and fresh pesto.

It’s wonderful served with some slaw or roast veg or part of a large festive spread.

Creating this dish brought back lots of lovely memories of a dish in a cosy little vegetarian café I used to go with my mum–the food was rustic and wholesome and a favourite growing up. I love it when food evokes fond memories, especially at Christmas.

Have you made a galette before?

It’s an easy and quick way of making a rustic tart, and in this recipe it’s created with California Walnuts. It was a great opportunity to include some wonderful walnuts on the tart base and on top. Gorgeous!

I love walnuts! And the taste and texture of California Walnuts makes them an incredibly versatile ingredient for all kinds of festive dishes such as tarts, salads, nut roasts, cakes, biscuits and much more.

I really hope you love this recipe.

Enjoy, Niki xx

About California Walnuts

Any walnuts sold in the UK that say Produce of California or Produce of the USA will be from California. Many stores and brands sell packs of walnuts that are from California year-round, such as Home Bargains, Tesco, Sainsbury’s and more.

Did you know! For great tasting walnuts all the time, they are best kept in the fridge. For longer storage, place them in the freezer for up to 12 months.

And–all you need is a handful a day to get the benefits of California Walnuts.

I think that California Walnuts are the best in the market and their packs are identifiable with a sticker or label which states: Produce of California or Produce of the USA.

And, here are a few nutritional facts;

Walnuts are the only tree nut to contain a rich source of the plant-based omega-3, alpha-linolenic acid (ALA), 2.7g/ 30g* which the body can’t make on its own so must come from food.

30g of California Walnuts* offers 4.4 g of protein and 1.4 g of fibre.

A handful a day is all you need to get the health and nutrition benefits of California Walnuts.
