Vegan French Onion Shepherd’s Pie Ingredients

A wholesome, hearty recipe awaits!

For the Filling

Olive Oil – Adds richness and aids in sautéing; substitute with avocado oil for a different flavor profile.
Onions (4 large, thinly sliced) – The sweet base of the filling, caramelizing beautifully for that signature taste.
Garlic (3 cloves, minced) – Enhances the depth of flavor; use garlic powder if fresh isn’t available.
Dried Thyme (1 tsp) – Adds an earthy note; fresh thyme can be used as a delightful substitute.
Bay Leaf (1) – Provides aromatic essence while cooking; remember to remove it before serving.
Tomato Paste (2 tbsp) – Boosts the umami flavor, enriching the overall taste of the filling.
French Green Lentils (1 cup, rinsed) – The primary protein source, maintaining shape during cooking; brown lentils work if you’re in a pinch.
Sherry Vinegar (2 tbsp) – Adds necessary acidity to balance richness; balsamic vinegar is a suitable replacement.
Tamari/Soy Sauce (2 tbsp) – Offers depth of flavor; swap with coconut aminos for a soy-free option.
Vegetable Stock (4 cups) – A flavorful base for the filling; homemade stock elevates the dish’s taste significantly.
Salt and Black Pepper – Essential seasoning to adjust according to taste.

For the Cauliflower Potato Mash

Cauliflower Florets (2 cups) – The main ingredient providing a low-calorie filler.
Peeled and Diced Potatoes (2 cups) – Adds creaminess to the mash; choose waxy potatoes for the best texture.
Garlic (2 cloves, smashed) – Infuses additional flavor into the mash; feel free to use garlic powder as a substitute.
Vegan Butter (2 tbsp) – Enriches the mash with creaminess and flavor.
Unsweetened Non-Dairy Milk (¼ cup) – Achieves the desired creaminess in the mash; almond, oat, or cashew milk are excellent choices—but avoid coconut to keep the flavor balanced.
Nutritional Yeast (2 tbsp) – Adds a cheesy flavor; it’s optional if you don’t have it on hand.

For Garnish

Fresh Thyme Leaves – Perfect for enhancing presentation and adding fresh flavor.
Drizzle of Olive Oil – Adds richness and a lovely finishing touch to your pie.

How to Make Vegan French Onion Shepherd’s Pie

Prepare the Filling: Heat olive oil in a large pan over medium heat. Add sliced onions and sauté until they are beautifully caramelized and golden brown, about 25-30 minutes. Stir in minced garlic, dried thyme, bay leaf, and tomato paste; cook for an additional 3-5 minutes to meld the flavors together.
Add the Lentils: Pour in the rinsed lentils, sherry vinegar, tamari, and vegetable stock. Bring to a simmer, then reduce heat and cook until lentils are tender and delicious, roughly 30-40 minutes. Season with salt and black pepper to taste.
Make the Cauliflower Potato Mash: In a large pot, boil cauliflower and diced potatoes until fork-tender, about 15-20 minutes. Drain and return to the pot. Add smashed garlic, vegan butter, non-dairy milk, and nutritional yeast. Mash until creamy and smooth, adjusting seasoning with salt and pepper.
Assemble the Pie: Preheat your oven to 400°F (200°C). In a baking dish, layer the lentil filling evenly. Spread the creamy cauliflower potato mash on top, creating decorative swirls for a beautiful finish.
Bake to Perfection: Bake the assembled pie in the oven for approximately 30-40 minutes, until the top is slightly golden and everything is heated through. For a crispy topping, consider broiling for an extra 2-3 minutes.

Optional: Garnish with fresh thyme leaves and a drizzle of olive oil before serving for an extra touch of flavor.
