When you think of comfort food, hearty shepherd’s pie might come to mind. It’s warm, satisfying, and full of flavor.
But traditional recipes are often loaded with high-fat meats and calorie-heavy potatoes. What if you could enjoy the same cozy vibes in a healthier, weight-loss-friendly version? Enter Tuna and Sweet Potato Shepherd’s Pie!
This lighter twist on the classic swaps out ground meat for protein-packed tuna and uses creamy sweet potatoes instead of regular mashed potatoes. Not only is it nutritious, but it’s also simple to make and perfect for meal prep.
Let’s explore how this dish checks all the boxes for taste, nutrition, and weight-loss goals.
Why Tuna and Sweet Potato Shepherd’s Pie is a Weight Loss Winner
When crafting meals for weight loss, the goal is to pack in nutrients without piling on unnecessary calories. This recipe excels in that area. Here’s why:
- High-Protein, Low-Calorie Tuna: Tuna is a fantastic lean protein option, with about 20 grams of protein per 3 ounces and just 100 calories. Studies have shown that high-protein meals can increase feelings of fullness, helping you eat less throughout the day.
- Sweet Potatoes for Complex Carbs: Sweet potatoes are a nutrient powerhouse. They’re high in fiber, which supports digestion and keeps you feeling full. A medium sweet potato contains only about 100 calories and provides 4 grams of fiber.
- Vegetables Galore: This recipe includes a medley of vegetables like carrots, peas, and onions, adding vitamins and minerals while keeping the calorie count low.
Plus, this dish fits a variety of dietary plans, including gluten-free and low-fat lifestyles.
Ingredients for Tuna and Sweet Potato Shepherd’s Pie
Here’s everything you’ll need to make this wholesome casserole:
For the Mashed Sweet Potato Topping:
- 3 medium sweet potatoes, peeled and chopped
- 2 tablespoons low-fat milk (or unsweetened almond milk)
- 1 tablespoon olive oil or butter
- Salt and pepper to taste
For the Tuna Filling:
- 2 cans (5-6 oz each) tuna in water, drained
- 1 tablespoon olive oil
- 1 small onion, finely diced
- 2 carrots, finely diced
- 1 cup frozen peas
- 1 tablespoon tomato paste
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- ½ teaspoon smoked paprika
- ½ cup low-sodium chicken or vegetable broth

Step-by-Step Recipe: Tuna and Sweet Potato Shepherd’s Pie
1. Prepare the Sweet Potato Topping
- Boil the Sweet Potatoes: Place the sweet potato chunks in a pot of salted water. Bring to a boil and cook for 15-20 minutes or until tender.
- Mash the Potatoes: Drain the potatoes and mash them with the milk, olive oil or butter, salt, and pepper. Set aside.
2. Make the Tuna Filling
- Sauté the Vegetables: Heat the olive oil in a large skillet over medium heat. Add the onions and carrots, and cook for 5-7 minutes until softened.
- Add Seasonings and Peas: Stir in the tomato paste, garlic powder, thyme, and smoked paprika. Add the peas and cook for another 2-3 minutes.
- Incorporate the Tuna: Flake the tuna into the skillet and mix gently. Pour in the chicken or vegetable broth, allowing the mixture to simmer for 3-5 minutes. Season with salt and pepper to taste.
3. Assemble the Shepherd’s Pie
- Layer the Tuna Mixture: Spread the tuna filling evenly in a baking dish.
- Add the Sweet Potato Topping: Spoon the mashed sweet potatoes over the tuna mixture, spreading it out evenly. Use a fork to create decorative ridges on the surface if you’d like.
- Bake: Preheat the oven to 375°F (190°C). Bake the casserole for 20-25 minutes, or until the sweet potato topping is slightly golden.
4. Serve and Enjoy

Fun Facts and Nutritional Insights
- Sweet Potatoes vs. Regular Potatoes: Sweet potatoes rank lower on the glycemic index than white potatoes, meaning they cause a slower, steadier rise in blood sugar levels—a benefit for weight loss.
- Tuna’s Omega-3 Content: While tuna in water has less fat, it still provides some omega-3 fatty acids, which promote heart health and may even help with fat metabolism.
- Vegetables in Weight Loss: Eating fiber-rich vegetables like carrots and peas has been shown to reduce overall calorie intake by making meals more satisfying.
Tips for Success
- Customize Your Vegetables: Swap out peas for green beans or add mushrooms for an earthy flavor.
- Make It Dairy-Free: Use almond milk and a vegan butter substitute for the mashed sweet potato topping.
