Ingredient Highlight

Below is a breakdown of each ingredient, why it matters, and how it contributes to the overall flavor and texture of the Veggie Steak Slice.

Ingredient Purpose Tips & Variations
Olive oil (2 tbsp) Medium‑heat cooking oil that imparts a subtle fruity note. Use a light‑flavored olive oil to keep the focus on the filling.
Onion, very finely chopped (1) Provides a sweet, aromatic base. For a milder flavor, use red onion or shallots.
Chestnut mushrooms, roughly chopped (250 g) The primary umami component; chestnut mushrooms have a nutty, slightly sweet taste. Substitute with cremini or button mushrooms if chestnut mushrooms are unavailable.
Smoked tofu, finely chopped (100 g) Adds a smoky depth and protein boost. For a more pronounced smoke flavor, use smoked tempeh.
Tomato purée (½ tbsp) Adds acidity and body. Use a high‑quality tomato purée for richer flavor.
Mushroom ketchup (1 tbsp) A concentrated mushroom sauce that brings intense umami. If you can’t find mushroom ketchup, mix 1 tbsp of soy sauce with 1 tbsp of tomato paste.
Brown rice miso (½ tbsp) Enhances depth and saltiness. White miso will be milder; try it for a lighter taste.
Ground black pepper (¼ tsp) A subtle heat and complexity. Add a pinch of cayenne for a kick.
Vegetable stock (150 ml, not hot) Provides moisture and ties flavors together. Use low‑sodium stock to control salt levels.
Cornflour (2 tbsp) Thickens the filling into a cohesive, spreadable mixture. Arrowroot powder works similarly if you’re avoiding gluten.
Puff pastry (500 g block) The star of the show—flaky, buttery, and golden. Pre‑freeze a pastry sheet for a quick prep if you’re short on time.
Plant‑based milk or 1 large egg, lightly beaten (50 ml) Egg wash or milk wash gives the pastry a glossy finish. For a vegan version, use oat milk or a vegan egg replacer.
Mustard, peas, chunky chips (optional) Classic accompaniments that add crunch, color, and a tangy contrast. Swap peas for a side of roasted sweet potatoes for a different twist.

Why These Ingredients Matter

The heart of the Veggie Steak Slice lies in the balance of umami, smokiness, and subtle acidity. Chestnut mushrooms provide a robust, earthy base; smoked tofu adds a smoky undertone that mimics steak. Tomato purée and mushroom ketchup give acidity and depth, while brown rice miso and black pepper bring savory complexity. Cornflour ensures the filling holds together, creating a cohesive “steak” that doesn’t fall apart when sliced. The puff pastry not only offers a buttery, flaky crust but also serves as a neutral canvas that lets the filling shine.

Step‑by‑Step Instructions

Below is a clear, numbered guide to creating your Veggie Steak Slice. Each step is designed to flow naturally into the next, ensuring a smooth cooking experience.

  1. Sauté the Base
    Heat the olive oil in a frying pan over low‑medium heat. Add the finely chopped onion and a pinch of salt. Cook for 10 minutes, stirring occasionally, until the onion softens and begins to caramelize. Meanwhile, use a food processor to blitz half of the chestnut mushrooms until they’re finely chopped. Add these processed mushrooms to the pan along with the remaining roughly chopped mushrooms. Sauté for another 10 minutes, allowing the mushrooms to release their moisture and develop a rich, brown color.

  2. Incorporate the Protein & Umami Boosters
    Stir in the finely chopped smoked tofu and cook for 5 minutes, letting it absorb the onion and mushroom flavors. Add the tomato purée, mushroom ketchup, brown rice miso, and ground black pepper. Cook for 1 minute, ensuring the mixture is well combined and fragrant. In a small cup, whisk together 50 ml of vegetable stock and the cornflour until smooth. Pour the remaining 100 ml of stock into the pan, bring to a gentle simmer, and then stir in the cornflour mixture. Simmer uncovered for 5 minutes, allowing the sauce to thicken. Taste and season as needed. Set the filling aside to cool completely—this step is crucial for the pastry to seal properly.

  3. Prepare the Pastry
    Preheat your oven to 180 °C (fan or gas 6). Lightly dust a clean work surface with flour and roll out the puff pastry to the thickness of a £1 coin. Cut out eight 12 cm × 15 cm rectangles, re‑rolling the trimmings as needed. Place four of the rectangles on a large lined baking sheet. Divide the cooled mushroom‑tofu mixture evenly among them, leaving a border around the edges. Brush the exposed pastry edges with the beaten plant‑based milk or egg wash. Place another pastry rectangle on top of each filling, seal the edges by pressing and crimping with a fork. Score a criss‑cross pattern on the top of each parcel to allow steam to escape during baking. Chill the assembled parcels in the refrigerator for 30 minutes to firm the pastry and prevent sticking.

  4. Bake to Perfection
    Brush the remaining milk or egg wash over the top of each slice. Bake in the preheated oven for 40‑45 minutes, or until the pastry is golden brown and puffed. Once baked, allow the slices to rest for 10 minutes before serving. This resting period lets the juices redistribute and makes slicing easier.

  5. Serve
    Plate the Veggie Steak Slices with your choice of accompaniments—crisp mustard, peas, and chunky chips add a delightful contrast. For a lighter side, try a fresh salad or steamed broccoli. Enjoy while the pastry is still warm and the filling is juicy.
