Ingredients You’ll Need
All simple, everyday ingredients nothing exotic required.
- 2 medium sweet potatoes, peeled and cubed
- 1 can (15 oz) lentils, drained and rinsed
- 1 cup frozen mixed vegetables (peas, carrots, corn)
- 1 small onion, chopped
- 2 tablespoons olive oil, divided
- 1 tablespoon soy sauce or tamari
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- Salt and pepper, to taste
How to Make Sweet Potato Shepherd’s Pie
Step 1: Cook and Mash the Sweet Potatoes
Bring a pot of salted water to a boil. Add cubed sweet potatoes and cook 10–12 minutes, until tender.
Drain and mash with 1 tablespoon olive oil, salt, and pepper.
💡 Tip: For extra creamy mash, stir in a splash of plant milk or a small knob of vegan butter.
Step 2: Make the Lentil-Veggie Filling
While potatoes cook, heat 1 tablespoon olive oil in a skillet over medium heat. Sauté onion 3–4 minutes until soft and fragrant.
Add lentils, mixed veggies, soy sauce, garlic powder, and thyme. Season with salt and pepper. Cook 5 minutes, stirring, until flavors meld and mixture is heated through.
Step 3: Assemble and Broil
Spread the lentil-vegetable mixture evenly in an 8×8-inch baking dish. Top with mashed sweet potatoes and smooth with a spatula.
Broil for 3–5 minutes until the top is lightly golden and edges are slightly crisp. Serve warm.
Serving Ideas
This shepherd’s pie is a full meal on its own, but pairs well with:
- A fresh green salad with lemon vinaigrette
- Roasted Brussels sprouts or green beans
- Crusty bread to scoop up all the flavors
For meal prep, portion into containers once cooled. Keeps in the fridge up to 4 days and reheats perfectly in the microwave or oven.
Why Sweet Potatoes Work So Well
Sweet potatoes add natural sweetness that complements the savory lentil filling. They’re also full of:
- Vitamin A for healthy skin and eyes
- Fiber for digestion
- Complex carbs that keep you full and energized
Plus, they caramelize beautifully under the broiler, giving the shepherd’s pie a gorgeous golden top.
Make It Your Own (Fun Variations)
- Add mushrooms for a richer, “meaty” flavor
- Swap in different veggies like spinach, kale, or bell peppers
- Use mashed cauliflower instead of sweet potatoes for a lower-carb version
- Stir in tomato paste or vegan Worcestershire sauce for deeper flavor
- Sprinkle breadcrumbs on top for an extra-crispy finish
Experimenting is encouraged this recipe is very flexible!
Storage and Reheating Tips
Leftovers? Even better the next day!
- Fridge: Store in an airtight container up to 4 days
- Freezer: Portion and freeze up to 2 months. Thaw overnight in the fridge
- Reheat: Oven 375°F (190°C) for 10–15 mins or microwave until hot
💡 Pro tip: Add a drizzle of olive oil or splash of vegetable broth when reheating to keep the mash moist.
FAQs About Sweet Potato Shepherd’s Pie
Can I use canned sweet potatoes?
Fresh taste best, but microwaving peeled chunks 6–7 minutes works in a pinch.
What can replace lentils?
Cooked chickpeas, crumbled tempeh, or vegan ground “meat” all work well.
Can I make this ahead?
Yes — assemble a day in advance, cover, refrigerate, then bake 15–20 mins at 375°F.
Is it gluten-free?
Yes — just use tamari instead of soy sauce and check your veggie mix for added sauces.
How to make the mash creamier?
Add a splash of unsweetened almond milk or a bit of vegan butter before spreading on top
