- 720 ml (3 cups) vegetable broth
- 120 ml (1/2 cup) passata or crushed tomatoes
- 1 tablespoon soy sauce or tamari (for gluten-free)
- 1 tablespoon dried mixed herbs (like oregano, thyme, rosemary)
- 1 teaspoon smoked paprika
- 1/2 teaspoon salt, or to taste

Step-by-Step Instructions
-
Step 1: Prepare the Potatoes
Place the peeled and chopped potatoes in a large pot. Cover them with cold water, adding about an inch of water above the potatoes. Bring to a boil over high heat, then reduce heat to medium and simmer until the potatoes are very tender, about 15-20 minutes. Small tip: Use a fork to test the doneness; it should slide in easily.
-
Step 2: Start the Filling Base
While the potatoes cook, heat the olive oil in a large, oven-safe skillet or Dutch oven over medium heat. Add the chopped onion, carrots, and celery. Sauté for 8-10 minutes, until the vegetables begin to soften. Stir occasionally to prevent sticking.
-
Step 3: Add Aromatics and Lentils
Add the minced garlic to the skillet and cook for another minute until fragrant. Stir in the rinsed lentils, vegetable broth, passata, soy sauce, dried herbs, smoked paprika, salt, and pepper. Bring the mixture to a gentle simmer.
-
Step 4: Cook the Lentil Filling
Reduce the heat to low, cover the skillet, and let it simmer for 20-25 minutes. Cook until the lentils are tender and most of the liquid has been absorbed. Stir occasionally to ensure even cooking and prevent the lentils from sticking to the bottom. Small tip: If the mixture seems too dry before the lentils are cooked, add a splash more broth.
-
Step 5: Finish the Potato Topping
Drain the cooked potatoes thoroughly. Return them to the hot pot. Add the plant-based milk, vegan butter or olive oil, salt, and pepper. Mash the potatoes with a potato masher or a large fork until smooth and creamy. Taste and adjust seasoning as needed.
-
Step 6: Add Frozen Vegetables to Filling
Once the lentils are tender and the liquid has reduced, stir in the frozen peas and corn into the lentil mixture. Cook for another 2-3 minutes, just until the vegetables are heated through. The filling should be thick and hearty.
-
Step 7: Assemble the Casserole
Preheat your oven to 190°C (375°F). If your lentil filling was made in an oven-safe skillet, you can use that directly. Otherwise, transfer the filling to a 9×13 inch baking dish. Carefully spoon the mashed potato topping evenly over the lentil filling, spreading it to the edges. You can create decorative swirls with a fork if you like.
-
Step 8: Bake to Golden Perfection
Bake the casserole in the preheated oven for 20-25 minutes, or until the filling is bubbly and the mashed potato topping is lightly golden brown. For an extra golden crust, you can briefly place it under the broiler for 1-2 minutes, watching carefully to prevent burning. Small tip: Keep a close eye on it under the broiler, as it can brown very quickly.
-
Step 9: Serve and Enjoy
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the filling to set slightly. Garnish with fresh chopped parsley, if desired. Serve hot and enjoy your delicious homemade Vegetarian Shepherd Casserole!
Tips & Variations
- Gluten-Free Option: This recipe is naturally gluten-free if you use tamari instead of soy sauce. Always check labels for vegetable broth and other packaged ingredients to ensure they are certified gluten-free.
- Vegan Option: This recipe is already 100% vegan! We use plant-based milk and vegan butter, making it suitable for all vegan diets.
- Add More Vegetables or Protein: Feel free to add diced mushrooms, chopped bell peppers, or spinach to the lentil filling for extra nutrients and flavor. For more protein, you could add cooked black beans or crumbled firm tofu along with the lentils.
- Spicy Version: For a kick, add 1/2 teaspoon of red pepper flakes to the lentil filling along with the other spices. A pinch of cayenne pepper also works wonderfully.
- Cheesy Topping: For a cheesy twist, sprinkle about 1/2 cup of your favorite dairy-free shredded cheese over the mashed potatoes before baking. It will melt and create a lovely golden crust.
