Healthy gardener’s pie recipe – Unofficial Slimming World vegetarian recipe
This Gardener’s Pie is a vegetable pie that is full of flavour and vegetarian and vegan, so it will really suit most people you are cooking for.
It is something I love to make during the winter months, it is so warming and feels like real comfort food.

Easy adaptations to the Gardener’s Pie recipe
To save money, time, or even just to change the taste a little, I have tried the following adaptations.
Sometimes I use frozen chopped spinach instead of fresh. I use the ones that come in little inch-sized blocks and are available at most supermarkets. When I make this, I use around 8/9 in this recipe, and it seems a good amount.

I sometimes replace the parsnips with swede and even make swede mash on top. This makes it suitable for a lower-carbohydrate day or if following Slimming World SP day.
I regularly use lazy garlic, which is in a jar in white wine vinegar, instead of chopping garlic myself. I also like frozen garlic as it is so easy just to add a block or two!
It is probably a little more expensive but much quicker, and you don’t end up with hands smelling of garlic!
I never peel the carrots or parsnips and just make sure they are clean. Equally, I don’t always bother with the parsley on the top. It is still just as yummy, but saves a little time!

Eating Gardener’s Pie for weight loss
If you follow Slimming World, Weight Watchers (WW), Noom or any other weight loss plan, you can usually count the ingredients within this recipe in your allowances. This makes a great Slimming World vegetarian pie as it has so much flavour without any SWIPs or syns!
It is, of course, important to check the plan you follow and remember that all nutritional information and ingredients are in the recipe card below.
If you follow Slimming World, you will know the general principle of having one-third of your meals be speed vegetables. This Gardener’s Pie recipe is made with approximately 1/3 of the speed vegetables. That doesn’t mean you can’t serve it with vegetables if you want to!
Making it easy for all the family to make, whether they are following Slimming World or not!
If you are a bit rubbish at mashing potatoes like me, then why not try the Masha? It could make lovely smooth mashed potatoes for the top of your Gardener’s pie easily.

Can you make Gardener’s Pie in the slow cooker?
This is not an easy swap, but you can make something a little like the Gardener’s pie.
Simply put all the ingredients in a slow cooker and cook on low for 4-5 hours.
Instead of mashing the potatoes, chop them up into chunks and make a Gardener’s Vegetable Casserole.
Alternatively, make the Gardener’s pie base in the slow cooker during the day, then add mashed potatoes and finish it in the oven when you get home.
