If you need a great holiday dinner idea, this mushroom pot pie is easy to make, vegan (or vegetarian, depending on your needs), and absolutely delicious. I’m not a huge mushroom fan and I love this.
When I first switched to vegetarianism in my late teens, I was always so disappointed by the veg options at the holiday table. It was mashed potatoes and salad, no main for us. I think that vegetable pies are a wonderful option to provide that centrepiece for a plant-based main, both looking impressive and tasting great.
The mushroom filling can be made in advance and chilled until adding the pastry and baking. If you have a lot to make on the day you want to serve, you may want to consider doing this ahead of time.
Ingredient Notes and Substitutions
- Mushrooms: a mix is ideal for best flavour and texture. I used oyster, cremini, king trumpet, and shiitake. Use mushrooms that you like. All button mushrooms won’t be good, but you should use a mix of varieties that you would typically eat. Canned are a no-go.
- Carrots: if you don’t want to use carrots, you can sub another vegetable like leek or potato, or leave them out altogether.
- Wine: dry white wine is ideal. If you don’t drink wine or avoid alcohol, a small amount of white wine vinegar can replace the wine. Use 1-2 teaspoons depending on your desired level of acidity, and use it in the same way to deglaze the pan.
- Herbs: rosemary and thyme. Oregano would also be good, as would sage. See substitutions for thyme.
- Arrowroot: to thicken the base. Cornstarch can be used in an equal amount.
- Water or vegetable broth: water is perfectly fine, as long as you season effectively. Use mushroom broth for a stronger mushroom flavour. There’s always one person who gets upset about the option to use water instead of broth or stock – but as long as you know how to add salt, of course you can use water. Store-bought stock cubes are essentially salt and a bit of starch and fat.
- Cashew cream cheese: this is optional, but replaces the heavy cream used in a typical pot pie. It adds a nice extra layer of creaminess (pictured had pepper added).
Step by Step
Step 1: make the filling and set it aside to cool before proceeding.
Step 2: top with the rolled out puff pastry.
Step 3: crimp the edges and make a few slits for steam to escape.
Step 4: bake until golden, about 22 minutes, and serve hot.
It is vitally important to sear the mushrooms. They should be cooked on high heat, stirring very minimally, until any water has evaporated and they are browned. This creates the best texture (not soggy or chewy) and flavour.
If puff pastry isn’t your thing, use a spelt coconut oil pastry instead. The cooking time will vary slightly, so cook until browned. Most store-bought puff pastry is made without dairy products, but you’ll have to check the ingredient list.
If the pie doesn’t need to be vegan, you can top with an egg wash before baking.
