Step-by-Step Guide to Making Mary Berry Vegetarian Cottage Pie

Step 1: Prepare the Mashed Potato Topping

Boil potatoes in salted water for about 15 minutes or until tender. Drain, mash with butter and milk, and season with salt and pepper. Set aside.

Step 2: Cook the Vegetable Base

In a large frying pan, heat olive oil over medium heat. Add onions, carrots, celery, and garlic. Cook for 5–7 minutes until softened. Add the chopped mushrooms and cook for another 5 minutes until they release their juices.

Step 3: Add the Lentils and Sauce Ingredients

Stir in tomato purée, chopped tomatoes, herbs, soy sauce (if using), and lentils. Pour in the vegetable stock and bring to a simmer. Cook uncovered for 10–15 minutes until the mixture thickens slightly. Season to taste.

Step 4: Assemble the Cottage Pie

Preheat the oven to 190°C (375°F). Spoon the lentil and vegetable mixture into a baking dish and spread evenly. Spoon mashed potatoes over the top and smooth with a spatula. Use a fork to create texture on the surface for crispness.

Step 5: Bake Until Golden

Bake for 25–30 minutes until the top is golden and slightly crisp around the edges. Allow to cool for a few minutes before serving.

What I Got Wrong (And How I Fixed It)

• Added too much liquid: Made the filling watery—next time, let it simmer longer to thicken.
• Didn’t season enough: Lentils absorb flavor; add salt and soy sauce to enhance taste.
• Overworked the mashed potatoes: Stirred too much, causing them to become gluey—mash gently instead.
• The top didn’t brown evenly: Brushed lightly with melted butter before baking for a golden crust.

Healthier Version of Mary Berry Vegetarian Cottage Pie

For a lighter version, use olive oil instead of butter, skimmed milk for the mash, and sweet potatoes instead of white potatoes for added vitamins and fiber. Reduce the oil in the vegetable base and use herbs and spices to enhance flavor naturally.
