Vegetarian cottage pie with tinned lentils is a comforting, hearty meal that combines the rich, savory flavors of a traditional shepherd’s pie with a meat-free twist. It’s perfect for both vegetarians and anyone seeking a nutritious and affordable dinner. Using canned lentils offers a quick and convenient alternative to cooking them from scratch, while still delivering protein, fiber, and texture. This dish is a staple for busy weeknights, family meals, or even meal prepping, offering both warmth and satisfaction in every bite.
Why Use Tinned Lentils in Cottage Pie
Quick and Convenient
Tinned lentils eliminate the need for soaking or boiling, making them an excellent choice for those short on time. Simply drain and rinse, and they’re ready to use in your recipe. This cuts prep time significantly while still allowing you to enjoy a protein-rich, plant-based meal.
High in Nutrition
Lentils are an excellent source of plant-based protein, iron, and dietary fiber. Even in canned form, they maintain much of their nutritional value. They’re also low in fat and contain complex carbohydrates that help keep you full longer.
Ideal for Texture
The soft yet hearty texture of lentils makes them a great substitute for minced meat. They hold their shape well, soak up flavor from sauces and spices, and create a satisfying bite when layered beneath creamy mashed potatoes.
Ingredients for Vegetarian Cottage Pie with Tinned Lentils
For the Lentil Filling
- 1 can of green or brown lentils, drained and rinsed
- 1 onion, finely chopped
- 2 garlic cloves, minced
- 1 carrot, diced
- 1 celery stalk, chopped
- 1 tablespoon tomato paste
- 1 can chopped tomatoes or passata
- 1 tablespoon soy sauce or tamari
- 1 teaspoon dried thyme or mixed herbs
- 1/2 teaspoon smoked paprika (optional)
- Salt and pepper to taste
- Olive oil for cooking
For the Mashed Potato Topping
- 4-5 medium potatoes, peeled and chopped
- 2 tablespoons plant-based butter or olive oil
- 1/4 cup plant-based milk
- Salt and pepper to taste
- Nutritional yeast or grated vegan cheese (optional)
Step-by-Step Cooking Instructions
Step 1: Prepare the Mashed Potatoes
Boil the chopped potatoes in a large pot of salted water until they are soft usually about 15-20 minutes. Drain well, then return them to the pot. Add the plant-based butter and milk, and mash until smooth. Season with salt, pepper, and a little nutritional yeast if desired. Set aside while you prepare the filling.
Step 2: Sauté the Vegetables
In a large skillet or saucepan, heat a tablespoon of olive oil over medium heat. Add the onion and cook until soft and translucent. Stir in the garlic, carrots, and celery, and cook for about 5-7 minutes until the vegetables begin to soften.
Step 3: Add the Flavor Base
Stir in the tomato paste, allowing it to caramelize slightly for extra depth. Add the chopped tomatoes or passata, soy sauce, dried herbs, and smoked paprika if using. Stir well to combine and let the mixture simmer for 5 minutes.
Step 4: Add the Tinned Lentils
Gently fold in the rinsed lentils. Simmer everything together for another 10-15 minutes, allowing the flavors to blend and the mixture to thicken. Season with salt and pepper to taste. If the filling is too thick, you can add a splash of water or broth to loosen it slightly.
Step 5: Assemble the Pie
Preheat your oven to 200°C (400°F). Spoon the lentil filling into the base of a baking dish and smooth it out evenly. Spoon the mashed potatoes on top, spreading them out with a spatula or fork. You can create ridges on the top with the back of a fork to encourage browning.
Step 6: Bake
Place the dish in the oven and bake for 20-25 minutes, or until the top is golden and the filling is bubbling around the edges. If desired, switch on the grill for the last 2-3 minutes for a crispier potato topping.
Serving Suggestions
Vegetarian cottage pie with tinned lentils is hearty enough to serve on its own, but here are a few ideas to round out the meal:
