Mary Berry Vegetarian Cauliflour Humble Pie
Step back in time to when ‘umble pie’ was a staple for servants while nobles dined on prime venison. Today, Mary Berry’s version brings that humble dish to life, packed with flavor but oh-so-simple. Imagine a veggie feast: cauliflowers, leeks, mushrooms, and petit pois wrapped snugly in a crispy puff pastry crust. It’s history on a plate, but with a deliciously modern vibe, just waiting for you to dig in.

Why You’ll Like It

  1. Pie crust lid on top: Like many British pies, it uses a single pastry lid to cut down on calories while preserving that irresistible pie crust crunch and provides the perfect contrast to the creamy filling.
  2. Veggies taste great: The combination of cauliflower, leeks, and mushrooms creates a delicious and satisfying filling.
  3. Indulgent: The creamy cheese sauce adds a rich and indulgent element to the pie.

Mary Berry Vegetarian Pie with cauliflower and mushrooms is a great find! Filled with creamy cauliflower, cheesy mushrooms, and petit pois – it's heartwarming!


  • 1 large cauliflower
  • 2 leeks trimmed and cut into 2cm (¾in) slices
  • 115 grams 4 ounces frozen petit pois
  • 1 375 grams packet ready-rolled puff pastry
  • Knob of butter
  • 200 grams 7 ounces button mushrooms, halved
  • 1 egg beaten

For the cheese sauce:

  • 55 grams 2 ounces butter
  • 55 grams 2 ounces plain flour
  • 450 millilitres ¾ pint hot milk
  • 2 teaspoons Dijon mustard
  • 115 grams 4 ounces of mature Cheddar, coarsely grated
  • 55 grams 2 ounces Parmesan, coarsely grated


  • Preheat the oven and prepare a baking dish. Preheat the oven to 200°C/180°C Fan/Gas 6. Prepare a fairly deep 28cm (11in) diameter dish or a 3-pint dish.
  • Cook the green veggies. Break the cauliflower into small, even-sized florets, including chopping some of the smaller leaves. Bring a large pan of salted water to a boil. Boil leeks for 4 minutes, then add cauliflower florets and leaves, boiling for an additional 3 minutes until just tender. Drain, run under cold water to stop cooking, and set aside.
  • For the cheese sauce. Melt butter in a large saucepan over medium heat. Add flour, stirring for 1 minute. Gradually whisk in hot milk until thickened. Stir in mustard, Cheddar, Parmesan, salt, and freshly ground black pepper. Let it cool for 5 minutes.
  • Pan-fry the mushrooms. Heat butter over high heat, pan fry mushrooms for 3 minutes until golden, season with salt and pepper, and set aside to cool.
  • Mix all the veggies and put them in the baking dish. Add all cold vegetables and frozen peas to the cheese sauce, stir, and check seasoning. Spoon into the pie dish.
  • Cover the baking dish with pie crust. Unroll the pastry and set aside a 7cm (2¾in) strip from the short side, chilling it in the fridge. Roll out the remaining pastry slightly larger than the pie dish. Brush the beaten egg around the dish’s edge, place the pastry on top, and press down on the edges to seal. Trim any excess pastry with a sharp knife, make a small slit in the centre for steam to escape, and brush the top with a beaten egg.
  • Decorate the pastry and bake. Roll out the reserved pastry strip a bit thinner, then roll it up tightly. Using a sharp knife, slice it into long, thin strips. Unravel and dip them into the egg wash, then arrange on top of the pie in a random pattern. Bake in the preheated oven for about 40–45 minutes, until the pastry is golden, and the sauce is bubbling around the edges.
You will need a fairly deep 28cm (11in) diameter dish or a 3-pint dish.
The pie can be made, left unglazed, and stored covered in the fridge for up to 24 hours ahead.
Not suitable for freezing


  • The pie can be made ahead of time without adding the pastry lid. Keep covered in the fridge for up to 24 hours ahead.
  • Not suitable for freezing.


  • Swap the cauliflower for broccoli or a mix of your favourite vegetables. If you’re not in the mood for pastry but still crave a flavorful pie-like dish try my Vegetable Crumble Recipe. This savoury delight features potatoes, tomatoes, courgettes, peppers, and carrots, topped with a delectable crumble made from Parmesan cheese, oat flour, and vegan butter.
  • If you feel like eating squash I recommend Mary Berry’s Vegetarian Wellington with butternut squash, chestnut mushrooms, red peppers and goat cheese.
  • For a hearty option, give Mary Berry’s Chicken and Leek Pie Recipe a try. Whether you’re a chicken lover or not, omit or replace the chicken with vegetarian chicken chunks. It’s filled with creamy chicken, leek, and mushrooms and is cooked with Dijon mustard and apple juice. 
  • Looking for a vegan alternative? Check out the Vegan Quorn Chicken Pie Recipe, a plant-based take on the classic chicken pot pie. Loaded with mushrooms, carrots, corn, green beans, peas, and Quorn pieces, all simmered in a savory sauce of veggie broth, almond milk, and white wine.


Storage Instructions

Refrigerate: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until heated through before serving.

Freeze: Freeze for up to 3 months though Mary Berry doesn’t recommend freezing.
