How to Make Vegan Mushroom Pie with Ale & Lentils Recipe

Step 1: Prepare the Aromatics

Start by peeling and halving the shallots. Heat a splash of oil in your pan and cook the shallots gently until they begin to soften—that’s where all their natural sweetness shines through. Turn the heat down a bit, add chopped garlic or purée, and let that mellow, fragrant aroma fill your kitchen as it cooks for another two minutes.

Step 2: Add Mushrooms and Tomato Purée

Clean and chop your mushrooms into generous chunks. Toss in your tomato purée and mushrooms with the shallots and garlic, stirring as you increase the heat. Watch as the mushrooms start releasing their delicious juices, creating a flavorful base that’s full of lovely texture.

Step 3: Incorporate Lentils and Thickener

Rinse the puy lentils thoroughly to remove any dust or debris, then add them to the pan along with the cornflour. Stir everything together — this will ensure each spoonful is perfectly thick and satisfying.

Step 4: Pour in Ale and Vegetable Stock

Next, pour in the brown ale and vegetable stock, then cover the pan and bring everything to a gentle boil. Reduce to a simmer and let this cook for 30 minutes, stirring occasionally, so the flavors meld and the lentils absorb all the wonderful tastes.

Step 5: Soak and Add Porcini Mushrooms

While the filling simmers, soak the dried porcini mushrooms in boiling water for 20 minutes to rehydrate. Once softened, roughly chop the porcini and add them, along with their soaking liquid (for maximum flavor), back into the pan. This addition brings an irresistible savory richness.

Step 6: Final Cooking and Thickening

With the lid off, continue to cook until the lentils have just the right bite—tender but not mushy—and the sauce is thick, glossy, and ready to be spooned into your pie dish. If it gets too thick, a splash of water will loosen it perfectly.

Step 7: Assemble the Pie

Preheat your oven to 180ºC (350ºF, Gas Mark 4). Spoon the filling into your pie dish and unroll the puff pastry. Feel free to cut out some fun shapes or decorative patterns on the pastry for a whimsical touch. Brush the edges of the dish with water, place the pastry on top, trim excess, and crimp edges with a fork for a tidy finish.

Step 8: Glaze and Bake

Mix some dairy-free milk and a few drops of soy sauce for a glossy glaze, then brush this over the pastry. Pop your pie in the oven and bake for 20 minutes until the crust is irresistibly crisp and golden brown.

Garnishes

The beauty of this Vegan Mushroom Pie with Ale & Lentils Recipe is that it stands beautifully on its own, but some fresh parsley or thyme scattered on top adds a fresh, herbal brightness against the deep flavors. A light drizzle of balsamic glaze or a sprinkle of crushed nuts also brings dimension and a lovely finishing touch.

Side Dishes

This pie pairs wonderfully with vibrant, crisp salad greens tossed in a zingy vinaigrette to lighten the meal. Roasted root vegetables or steamed green beans offer colorful, nutritious side options that complement the savory richness without overwhelming the dish.

Creative Ways to Present

For a rustic vibe, try serving this pie in individual ramekins topped with puff pastry lids. It’s perfect for cozy dinners or entertaining guests. Alternatively, scoop the filling alongside your favorite grain like quinoa or barley, and serve with a small slice of crust for a deconstructed yet just as delicious presentation.

Make Ahead and Storage

Storing Leftovers

You can store the pie leftovers covered in the refrigerator for up to 3 days. Make sure it is cooled completely before refrigerating to keep the pastry from getting soggy. Leftover pie can be a fantastic quick lunch or dinner option.

Freezing

This Vegan Mushroom Pie with Ale & Lentils Recipe freezes exceptionally well. Wrap the entire pie tightly in cling film and foil or portion out the filling and freeze separately. When ready, thaw overnight in the fridge for best results before reheating or baking.

Reheating

To reheat, warm the pie in a preheated oven at 180ºC (350ºF) for about 15-20 minutes or until the pastry crisps back up and the filling is piping hot. Using the oven rather than the microwave preserves that precious flaky crust texture.

FAQs

Can I use different types of mushrooms for this pie?

Absolutely! While chestnut and porcini mushrooms provide rich and earthy flavors, you can swap them for cremini, shiitake, or even portobello mushrooms depending on your preference and what’s available.

Is brown ale always vegan?

Can I make this pie gluten-free?

Yes, you can substitute the puff pastry with a gluten-free variety. Just make sure other ingredients like cornflour and soy sauce are gluten-free too, and you’ll have a delicious gluten-free version of this pie.

How long can I store the soaked porcini soaking liquid?

It’s best to use the porcini soaking liquid immediately for maximum flavor and safety. If you must store it, keep it in the fridge and use within 24 hours.

Can I prepare the filling in advance?

Definitely! The filling can be made a day ahead and refrigerated. Bring it back to room temperature before filling and baking the pie for the best texture and flavor.
