How to Make French Onion Shepherd’s Pie with Lentils and Creamy Cauliflower Potato Mash

  1. Sauté the Onions: Heat olive oil in a large soup pot over medium heat. Add sliced onions and sauté for about 45 minutes until they are softened and caramelized, stirring occasionally.
  2. Combine the Base Mixture: Once the onions are caramelized, sprinkle in the thyme, minced garlic, and add the lentils, tomato paste, vinegar, tamari, salt, and pepper. Pour in the vegetable stock, stir to combine, and bring to a boil. Once boiling, reduce the heat and simmer for 25–30 minutes until the lentils are tender.
  3. Cook the Vegetables: While the lentils cook, steam the chopped potatoes and cauliflower florets together for about 20 minutes until tender when pierced with a fork. Drain and return them to the pot.
  4. Mash the Vegetables: Add vegan butter and a splash of non-dairy milk to the potatoes and cauliflower. Mix in nutritional yeast, salt, and pepper. Mash everything together until you achieve a creamy consistency.
  5. Assemble for Baking: Preheat your oven to 375°F (190°C). In an oven-safe skillet, layer the lentil mixture evenly at the bottom, then top with the creamy mash. Drizzle with a bit more olive oil.
  6. Bake: Place the skillet in the oven and bake for 25 minutes or until the top is golden and bubbly. Allow it to rest for 5 minutes before serving.

Tips for Success

  • Don’t Rush the Onions: The longer you let the onions cook, the sweeter and more flavorful they will become.
  • Check Lentils: Keep an eye on the lentils while cooking; you want them tender but not mushy.
  • Creamy Mash: For the creamiest texture, use a potato ricer or food mill for mashing.
  • Serve Warm: Allow the dish to cool before serving to help maintain its structure and flavor.

Easy Variations

  • Protein Boost: Add cooked lentils, chickpeas, or even vegan sausage crumbles for more texture and protein.
  • Spice It Up: Incorporate a pinch of red pepper flakes for a kick.
  • Add More Veggies: Toss in other vegetables like spinach or mushrooms into the lentil mixture for added nutrition.
  • Serving Style: Instead of baking, try serving the lentil mixture in bowls and topping with a dollop of creamy mash.

What to Serve with French Onion Shepherd’s Pie with Lentils and Creamy Cauliflower Potato Mash

  • Simple Side Salad: A fresh green salad pairs wonderfully, balancing the richness of the dish.
  • Crusty Bread: Serve with crusty whole-grain bread for added texture and to soak up flavors.
  • Steamed Greens: Lightly steamed broccoli or green beans add a pop of color and nutrients.
  • Pickles: A side of tangy pickles can enhance the meal with their crunch and acidity.

Storage and Reheating

  • Refrigerator Storage: Store leftovers in an airtight container in the fridge for up to 4 days.
  • Freezer Storage: This dish freezes well. Store in an airtight container for up to 3 months.
  • Reheating: For best results, reheat in the oven to maintain crispness. Cover with foil to prevent drying out, or use the microwave for speed, stirring halfway through.

Common Mistakes to Avoid

  • Under-cooking the Onions: Skipping the caramelization step can lead to a less flavorful dish.
  • Not Monitoring Lentils: Overcooking lentils will turn them mushy; aim for tender yet intact.
  • Skipping the Rest Period: Letting the dish rest after baking helps it set, making it easier to serve.
