Slow Cooker Beef and Mushroom Pie Filling

This slow cooker beef and mushroom pie is an absolute delight and will please any pie lover.

Slow Cooker Beef and Mushroom Pie

By the time the slow cooker has finished cooking, you will be left with a rich beef pie filling ready to use in your favorite pie casing. It is always a massive hit whenever I make it for dinner.

You will be able to make enough pies to feed six people. Some extra side dishes will help feed even more people without needing to adjust the recipe. Alternatively, you can easily double or triple the recipe.

Even though this recipe is meant as a pie filling, it is excellent just as a stew. I sometimes love to serve it over the top of mashed potatoes.

Making the Pies

You can prepare this pie filling ahead of when you need it. For example, you can make the pie filling the day before and then simply scoop into the pie cases. Simply bake until the pastry is golden brown, and the pie filling is hot.

To make life easier when it comes to making the pie, you should take a look at a pie maker. They are super easy to use, but the downside is they can only do two to four pies at a time.

Puff Pastry Beef and Mushroom pie

Using pie tins is an excellent choice for making the perfect pies. I highly recommend that you blind bake the pastry. After this, simply add the pie filling and top with another piece of pastry. Bake until the pastry is golden brown.

The easiest method is to make some simple pot pies. Simply fill some ramekins with the pie filling and top with pastry. Bake in the oven until the filling is hot and the pastry is golden brown.

What to Serve with Beef & Mushroom Pie

There are many extras that you might want to have with this delicious pie. Below are a couple of ideas that work great for me.

Something like a cauliflower cheese will work incredibly well with these pies. It only takes a few minutes to cook and will help feed a hungry crowd.

For something a little unhealthy, you can make some cheesy potatoes in another slow cooker. It features slow-cooked potatoes with a generous amount of cheese and bacon. It is a must-try.

Beef and Mushroom Pie in the Slow Cooker

Nothing beats a delicious side of potato chips and green salad. I love to make some regular steak fries to go with the pie, but something like sweet potato fries will also work nicely.

Recipe Tips

  • I recommend using a cheap cut of meat, such as chuck beef. This choice in beef will keep costs down and ensure your pie filling turns out as flavorsome as possible.
  • You may need to thicken this slow cooker beef and mushroom pie filling with a mixture of cornstarch and water. Roughly two tablespoons of cornstarch mixed with a little bit of water should be more than enough.
  • I made use of button mushrooms for this recipe, but feel free to experiment with different types of mushrooms. They can radically change the dish, so keep this in mind when choosing a mushroom variety.

Note: I use a 5.5L (6 Quart) slow cooker (Amazon | Walmart) for all the recipes that I have on this website unless specified. If you have a smaller or larger slow cooker, then you might need to adjust the ingredients.
