Butternut Squash and Sweet Potato Mash - Pinch of Nom Slimming Recipes

For the full list of ingredients and comprehensive instructions, please see the recipe card at the end of this post. Before you scroll, there’s important stuff to know in the blurb!

Our Butternut Squash and Sweet Potato Mash is a really tasty, Autumnal side dish that works perfectly with sausages, roasted meats and stews.  You could even use it to top a Shepherd’s Pie!

This recipe creates a rustic mash – not smooth like potato versions – that’s very low in fat, suitable for vegans and has a really eye-catching, orange colour.  If you like your food a little spicier then simply replace the dried sage with chilli flakes to give this dish a spicy twist!

There’s no need to let the seeds from the butternut squash go to waste either.  Simply rinse them and place on an overproof tray before coating with a low calorie cooking spray.  Toss with a pinch of paprika, garlic granules and chilli flakes and then roast in a hot oven for around 15 minutes.  This quick trick will produce a really tasty snack or salad topping that’s just 20 calories per tablespoon!
