How to make mushroom and leek cottage pie
This is an easy recipe to make and much the same as a regular cottage pie but without the meat and potatoes!
When baked in the oven, the cauliflower topping forms a golden crust, adding a delightful contrast to the bubbling, flavorful mushroom and leek filling underneath. The aroma of the dish as it bakes is inviting, with a medley of savory scents wafting through the kitchen.
Boil the cauliflower until soft.
Mash with Cheddar, sour cream and butter.
Sautee leeks and mushrooms. Add stock and tarragon.
Add sour cream and mix well.
Layer the mushroom leek mixture into baking dish.
Top with the cauliflower mash and bake.
Let the pie rest for a few minutes after it's baked. This helps to set the layers and makes it easier to cut and serve.

Storage
Once the cottage pie has cooled to room temperature, cover it tightly with plastic wrap or transfer it to an airtight container.
Place the covered dish in the refrigerator.
This dish can typically be refrigerated for up to 3 to 4 days.
Freezing
If you'd like to freeze the cottage pie, it's best to freeze it before baking if possible. Assemble the pie but do not bake it.
Wrap the unbaked pie tightly with plastic wrap and foil to prevent freezer burn.
Label the package with the date and store it in the freezer.
It should keep well for up to 2 to 3 months when frozen.
Reheating
- To reheat a refrigerated vegetarian cottage pie, you can either reheat the whole dish in the oven or microwave individual portions.
- If reheating from frozen, it's best to thaw it in the refrigerator overnight before reheating.
- Reheat in the oven at around 350°F (175°C) for 20-25 minutes until it's heated through and the top is slightly golden and bubbly.
- Microwave individual portions until they are thoroughly heated.
Keto Cottage Pie Recipe Tips
Choose a variety of mushrooms like cremini, shiitake, or portobello for a more complex flavor.
Ensure the mushroom leek filling is not too watery. If the mushrooms release a lot of liquid during cooking, allow it to simmer for a bit longer to reduce the liquid content.
Make sure the cauliflower is well-cooked and very tender before blending. This will result in a smoother mash.
Drain the cooked cauliflower well to prevent excess moisture in the mash. Excess water can make the mash too runny.
When spreading the cauliflower mash, aim for an even layer to cover the entire surface. A fork or spatula can help create patterns or ridges, which will crisp up in the oven.
If you desire a golden crust, sprinkle a bit of cheese on top of the cauliflower mash before baking.
