What's for dinner?

Lentils and Maple~Mustard Sweet Potato Mash


This nutrient-rich dish is a flavourful vegan shepherd’s pie but since there are no animals like sheep or animal products in this dish (unless you use cow butter) I’d rather it have it’s own name like maybe Gardener’s pie. My husband and son, who eat meat occasionally, actually prefer this dish rather than the meat based one. (That’s a win!)

I use my dried soup base in this which kicks up the flavour. Ever since making it I’ve found many uses for it and I love adding it to my dishes rather than a store bought bouillon or stock. If you don’t have ready-made soup base then you could add half a veggie bouillon cube in the lentil mixture with a little water so that it dissolves.

If you have a mushroom hater in your midst ie: someone who doesn’t like the taste or texture of mushrooms (NOT someone that’s allergic) then mincing the mushroom is a great compromise. The texture is not detected when minced and mixed with the lentils as the lentils tend to be dry and the mushrooms hold lots of moisture which is released when cooked. It also adds nutrients like B vitamins and potassium as well as fiber and vitamin D which is so essential for the darker winter months.

This is a layered pie with the lentils on the bottom, they can get quite saucy so having it rest for about 10 minutes afterward is best. I also chose to sprinkle it with a little cinnamon just for looks but you could omit it too or use parsley.

The mustard is an important component as there are many different kinds. It’s important to get a grainy, hot stone ground variety rather than the bright yellow type. The kind I love to use in recipes is the Sierra Nevada brand which you can get here.


Besides being “good for you” or “healthy” (as some people that hear these words want to run in the opposite direction) this is a mix of sweet, savoury and rich umami (ooooo-mommy!) that just please all the taste buds!


This is packed full of goodness but may I suggest you serve it with a side garden salad?
