Butternut Squash as a Lower Calorie Alternative

If you struggle to do lower carb or low calorie meals because you think you will miss some of the foods that are off limits, then you just have to try this Chicken, Leek and Butternut Squash Bake.

Those flavours will have you wondering why you don't do lower carb days more often, just so you can make this dish.

Butternut squash is a great substitute for things like potatoes in a recipe and it's filling too.

Butternut Squash Recipes

Butternut Squash as a vegetable is so underrated. I have to buy at least one a week, because they are so versatile and can create many delicious dishes. Some of my favourites are:

  • Butternut Squash Fries
  • Roasted Paprika Butternut Squash
  • Creamy Butternut Squash Mac and Cheese
  • Roasted Butternut Squash Risotto
  • Spaghetti with Roasted Butternut Squash Sauce
  • Chicken and Rice Stuffed Butternut Squash
  • Chicken, Butternut Squash Coconut Curry Soup

with many more delicious Butternut Squash Recipesfor you to try.

Ghee for Cooking

I use ghee for infusing the garlic and herb flavour into the dish. You can use butter or even olive oil if you do not have ghee. If you want to keep it lower calories then by all means use spray oil, but that flavour is worth it in my opinion.

Incase you are wondering what ghee it. It's a clarified butter, which is a great fat for cooking with, it's natural and can be heated to high temps without going rancid like many man made oils. It's one of my favourite fats to cook with and well worth the 130 calories for 1 tablespoon, as that tablespoon will go a long way.

Can I add a more filling side?

If you can't do without the carbs, this dish is great with some rice, or Roast Potatoesor even these Crushed Roast Potatoes

You won't believe how delicious the sauce is on this Chicken, Leek and Butternut Squash Bake, that gets it's flavour from the infused ghee/butter and the sweeteness of that butternut squash.

Delicious Chicken, Leek and Butternut Squash Bake - tender chicken thighs with roasted butternut squash, juicy leeks and a cheesy parmesan topping.


  • 6 boneless skinless chicken thighs, raw
  • 3 large leeks, sliced
  • 1 onion, halved and sliced

  • 240ml (1 cup) of chicken stock
  • 1 tablespoon of ghee or butter


  1. Preheat oven to 200c or 400f
  2. Cut all the chicken thighs in half, to make small pieces.

  4. Add chicken pieces and cook until lightly golden.
  5. Set aside
  6. Add the onion and butternut squash and cook until the squash starts to soften. Add a little bit of the chicken stock at time, to prevent any from sticking to the pan.

  10. Serve with your choice of sides, but this dish is perfectly delicious all on it's own.

  18. Catie says

    Can you freeze this? Thanks

  19. Shevy (Slimming Eats) says

    Hi Catie - yes this will freeze fine.

  20. Carol says

    Absolutely delicious !

  21. Lorraine says

    This was seriously delicious Shevy! I loved the delicate subtle flavours of thyme and ghee. I didn't have butternut so used sweet potato and carrot, it worked well. Passed the husband test and got thumbs up ! Thanks for the recipe and your blog, love it here in Australia.

  22. Shevy (Slimming Eats) says

    Ahh thanks so much, Lorraine for such a lovely comment. I am so happy to read that you are enjoying the recipes on the blog.

  23. Edna says

    Hi Siobhan what approximate weight would you say a small butternut squash is as I live in Tenerife and they all look quite big here thank you x

  24. Shevy (Slimming Eats) says

    I wouldn’t worry too much about the weight, just dice and spread out evenly so it looks an even ratio to everything else, any leftover you can use in a soup or similar

  25. Babs Gough says

    I don't eat meat, could I substitute salmon or prawns for the chicken? Really like the look of the dish though.

  26. Shevy (Slimming Eats) says

    You sure can, but don’t add the shrimp or fish until later otherwise they will be over cooked.

  27. Sharon says

    Hi could you use a slow cooker for this recipe thanks

  28. Shevy (Slimming Eats) says

    This is best cooked in the oven.

  29. Paula says

    Lovely meal thanks for the recipe ! Can I freeze the leftovers?

  30. Shevy (Slimming Eats) says

    yes it freezes fine, enjoy 🙂

  31. Cally Ellis says

    My butternut had a very thin skin and broke when I was trying to scoop it out. In fairness, it was still quite hot so I may have been a bit clumsy with it. Anyway, I popped it all into a large gratin dish, topped it with the cheese as directed and it came out well. Very tasty, syn free and really want to say don’t panic if your squash breaks - just make it in a dish.

  32. Shevy (Slimming Eats) says

    the butternut squash should be cubed, peeled and added to this recipe raw? Not sure if you have confused with another recipe. But glad you enjoyed all the same.

  33. Kevan Trotter says

    Hi is this menu 1.5 ww per serving

  34. Emma Broughton says

    This was just beautiful. The first SP meal I have had from your 7 day plan. Can’t wait to try the others, I cannot believe this is only 1.5 syns

  35. L Gemmell says

    Absolutely delicious, cooked it to have some leftovers for lunch..... we all came back for more!

  36. Woody Davenport says

    A brilliantly tasty dish, one to repeat again and again. Thank you

  37. Clare says

    Had a load of homegrown butternut squash to use up and was looking for some different recipes. This was delicious, will definitely make again. Currently doing the fast 800 diet which is lowish carb and this fitted perfectly. Thank you 🙂

  38. Alison says

    Hi is butternut squash easy to peel? What is the best way? I’ve never cooked it before.

  39. Siobhan (Slimming Eats) says

    I use a sharp santoku knife. I just cut off the nose, the slice off each end to make flat, then you can carefully slice the skin off with the knife and dice. The nose part, you need to remove seeds and then chop into easier sized pieces to manage, but again the skin can be sliced off with a sharp knife. A good peeler will work too, but I prefer to use a knife.

  40. Sue Allen says

    OMG! This is amazing, even my husband loved it and he doesn't like chicken thighs or butternut squash!
    Thank you xxx

  41. Jane says

    Absolutely Delicious. I will be making this again!
