Hearty Lentil and Onion Shepherds Pie Ingredients
For the Base
- Olive Oil – Essential for sautéing onions and developing flavor; you can substitute with canola oil or avocado oil.

- Sea Salt and Black Pepper – These essential seasonings enhance the dish’s flavors; be sure to adjust to taste.
- Fresh Thyme Leaves – Adds a fresh, herbaceous note; if you’re out of fresh, you can use dried thyme at 1/3 the amount.
- Bay Leaf – Imparts depth and aroma to the cooking liquid; don’t forget to remove it before serving.
- Garlic Clove – Provides an aromatic punch when minced; if preferred, substitute with 1/4 teaspoon of garlic powder.
- Tomato Paste – This ingredient enriches the filling and brings umami notes.
- French Lentils – A hearty plant-based meat substitute; remember to rinse them; cooked green lentils can be an alternative.
- Sherry Vinegar or Balsamic – Adds a touch of acidity to balance the dish; red wine vinegar or apple cider vinegar works too.

For the Mash
- Yukon Gold Potatoes – Contributes creaminess to the mash; Russet potatoes can be used for a different texture.

- Vegan Butter – Ensures richness in the mash; regular butter or olive oil can be substituted based on your preference.
- Unsweetened Non-Dairy Milk – Vital for achieving the desired creamy consistency; for non-vegans, regular milk is a suitable alternative.

How to Make Hearty Lentil and Onion Shepherds Pie
-
Caramelize Onions: Heat olive oil in a large pot over medium heat, adding the sliced onions along with sea salt. Cook them slowly until they become deeply caramelized, which should take about 30-40 minutes. This step is crucial for developing a rich flavor.
-
Prepare Filling: Once the onions are ready, stir in minced garlic and fresh thyme. Then, mix in the tomato paste, rinsed lentils, vinegar, tamari, and vegetable stock. Simmer on low for 20-30 minutes, or until the lentils are tender. Don’t hesitate to add a splash of water if the mixture seems too dry.
-
Make Mash: While the lentils simmer, bring a separate pot of water to a boil with smashed garlic cloves. Add diced Yukon Gold potatoes and cook until tender, about 15 minutes. Add cauliflower florets and boil for another 5-7 minutes. Drain, then mash everything together with vegan butter, non-dairy milk, and nutritional yeast, seasoning with salt and pepper to your taste.
-
Assemble Pie: In a baking dish, layer the lentil mixture evenly at the bottom. Top it off generously with the creamy cauliflower-potato mash, creating a smooth surface, and drizzle a bit of olive oil on the top for added flavor.
-
Bake: Preheat your oven to 400°F (200°C) and place the dish in the oven. Bake for 25-30 minutes, or until the mash is golden brown and heated through, creating a beautiful crust.
Optional: For an extra touch, garnish with fresh thyme leaves before serving.
