Ingredients
Servings
6
- 2 cups dry green or brown lentils, rinsed
- 5 cups water or vegetable broth
- 1 medium onion, finely chopped
- 3 cloves garlic, minced
- 2 medium carrots, diced
- 1 cup celery, diced
- 1 cup mushrooms, chopped
- 1 cup frozen peas
- 1/4 cup tomato paste
- 1 tablespoon soy sauce or tamari (gluten-free option)
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon black pepper
- 1 teaspoon salt, divided
- 1 head cauliflower (about 1.5 pounds), cut into florets
- 1/4 cup unsweetened plant-based milk (e.g., almond or oat milk)
- 2 tablespoons olive oil, divided
- 1 tablespoon ground flaxseed + 3 tablespoons water (flax egg)
- Optional garnish
- fresh parsley, chopped
Instructions
-
Preheat oven to 375°F (190°C).
-
Make the flax egg by combining ground flaxseed and water in a small bowl; stir well and let it sit for 5–10 minutes until thickened.
-
In a medium saucepan, cook lentils with water or vegetable broth. Bring to a boil, then simmer uncovered for 25–30 minutes until lentils are tender but firm. Drain any excess liquid and set aside.
-
While lentils cook, steam cauliflower florets until very tender, about 10–12 minutes.
-
Heat 1 tablespoon olive oil in a large skillet over medium heat. Sauté onion, garlic, carrots, and celery until softened, about 7 minutes.
-
Add mushrooms and cook until they release moisture and start to brown, about 5 minutes.
-
Stir in tomato paste, soy sauce or tamari, dried thyme, rosemary, smoked paprika, black pepper, and half the salt. Cook for 2 minutes to develop flavors.
-
Add cooked lentils and frozen peas to the skillet. Stir to combine and cook another 3–4 minutes. Adjust seasoning with remaining salt if needed. Remove from heat.
-
In a large bowl, mash steamed cauliflower with plant-based milk, remaining 1 tablespoon olive oil, flax egg, and a pinch of salt until creamy and smooth. Use a hand masher or immersion blender for best results.
-
Transfer the lentil and vegetable mixture into a 9x13 inch (23x33 cm) baking dish. Spread the cauliflower mash evenly over the top, using a spatula to create texture for browning.
-
Bake uncovered for 25–30 minutes or until the top is lightly golden and the filling bubbles around the edges.
-
Let the shepherd's pie rest for 5 minutes before serving. Garnish with chopped fresh parsley if desired.
