Step‑by‑Step Instructions for Cottage Pie with Leek & Cauliflower Cheese
Step 1: Prepare the Base Ingredients
Begin by finely chopping the carrots, red onion, red pepper, mushrooms, and garlic. This mix of base ingredients is essential for a flavorful filling. Aim for uniform pieces to ensure even cooking. Set your chopping board and knife aside once finished, and you’re ready to sauté.
Step 2: Sauté the Vegetables
In a large frying pan, heat 2 tablespoons of olive oil over medium heat. Once the oil shimmers, add the chopped base ingredients and sauté for about 5 minutes. Stir occasionally until the vegetables soften and the onion becomes translucent. This process will deepen the flavors for your Cottage Pie with Leek & Cauliflower Cheese.
Step 3: Cook the Cauliflower and Leek
While the filling cooks, bring a pot of water to a boil. Carefully add the cauliflower florets and diced leeks, then cook for approximately 5 minutes until tender. Once cooked, drain the vegetables well to prevent excess moisture, which will help create a creamy topping later.
Step 4: Make the Vegetable Filling
Return to the frying pan with your sautéed vegetables and stir in 4 tablespoons of tomato purée and 150 ml of water. Add 1 teaspoon of tamari, along with the dried sage and thyme. Let the mixture simmer for another 5 minutes, allowing the flavors to meld beautifully before preparing your cheese sauce.
Step 5: Blend the Cauliflower Cheese Sauce
In the same pot used for boiling the cauliflower and leeks, combine the drained cauliflower and leeks with 2 tablespoons of vegan butter, 200 ml of oat or almond milk, 100 g of vegan grated cheese, and 1 heaped tablespoon of cornflour. Blend with an immersion blender until smooth and creamy to create your luscious cheese sauce.
Step 6: Preheat the Oven
While preparing to assemble your pie, preheat your oven to 180°C (350°F). This ensures a hot and even bake for your Cottage Pie, which is essential for achieving a golden, bubbling top.
Step 7: Assemble the Pie
In a baking dish, pour in the vegetable filling, spreading it evenly across the bottom. Next, spoon the creamy cauliflower and leek cheese sauce on top, making sure to cover the filling completely. This layer will create a delightful contrast in textures once baked.
Step 8: Bake Until Golden
Place the assembled Cottage Pie in the preheated oven and bake for approximately 30 minutes. Keep an eye out for a golden crust and bubbling cheese sauce—this is your cue that it’s ready to come out. The delightful aroma wafting through your kitchen will be irresistible!
Step 9: Serve and Savor
Once baked, take the pie out of the oven and let it sit for a few minutes before serving. This allows the filling to set slightly. Enjoy your warm Cottage Pie with Leek & Cauliflower Cheese alongside a side of steamed greens or a fresh salad for a wholesome meal!

Make Ahead Options
Preparing this Hearty Plant-Based Cottage Pie with Leek & Cauliflower Cheese ahead of time is a fantastic way to save precious minutes on busy weeknights. You can chop the base ingredients (carrots, onion, red pepper, mushrooms, and garlic) up to 24 hours in advance and store them in an airtight container in the refrigerator to keep them fresh.
