Ingredients You’ll Need

For the Mashed Potato Topping

• Russet potatoes: Create the soft, fluffy topping that covers the turkey filling.
• Chicken broth: Adds flavor and helps make the mashed potatoes creamy.
• Extra virgin olive oil: Gives the potatoes a smooth texture and rich flavor.
• Kosher salt and pepper: Season the potatoes to taste.

For the Ground Turkey Filling

• Ground turkey: Provides a lean, savory base for the casserole.
• Carrots: Add natural sweetness and texture.
• Onion: Builds flavor in the vegetable mixture.
• Red bell pepper: Adds color and a slightly sweet taste.
• Zucchini: Adds another layer of vegetable goodness to the filling.
• Garlic: Brings aromatic flavor to the vegetables and turkey.
• Tomato paste: Gives the filling a concentrated tomato flavor.
• Dried thyme: Adds an earthy herbal note.
• Cayenne pepper: Provides a little heat.
• Bay leaf: Adds depth while the filling simmers. Remove it before assembling the casserole.
• Frozen peas and corn: Add sweetness, color, and texture to the finished filling.
• Chicken broth: Helps the turkey and vegetables simmer together into a flavorful mixture.

Helpful Tips for the Best Shepherd’s Pie

• Cut the potatoes evenly: Similar-sized chunks cook at the same rate, making them easier to mash.
• Drain the potatoes well: Removing excess water helps prevent watery mashed potatoes.
• Brown the turkey: Cooking the ground turkey before combining it with the vegetables develops a savory base.
• Don’t rush the vegetables: Give the carrots, onion, and bell pepper enough time to soften before adding the garlic and zucchini.
• Remember the bay leaf: Remove and discard it before assembling the casserole.
• Create potato swirls: Use a fork to make decorative lines across the mashed potato topping. These add texture to the finished dish.
• Let it rest: Allow the casserole to rest for 10–15 minutes after baking so the layers can set before serving.

How to Make Healthy Ground Turkey Shepherd’s Pie

Step 1: Prepare the Potatoes

Peel the russet potatoes and cut them into chunks. Place them in a large pot and cover with cold water.
Add 1 teaspoon of salt and bring the water to a boil. Reduce the heat and simmer for about 15 minutes, or until the potatoes are fork-tender.
Drain the potatoes well. Mash them with ¾ cup of chicken broth, 3 tablespoons of extra virgin olive oil, and additional salt and pepper until creamy. Set aside.

Step 2: Brown the Ground Turkey

Preheat the oven to 400°F.
Heat 2 teaspoons of olive oil in a large cast iron skillet over medium heat. Add the ground turkey and cook until browned.
Use a slotted spoon to remove the turkey and transfer it to a plate. Drain any excess fat from the skillet.

Step 3: Sauté the Vegetables

Add 2 tablespoons of olive oil to the same skillet.
Add the chopped onion, carrots, and red bell pepper. Sauté for 5–7 minutes, until the vegetables have softened and become slightly browned.
Stir in the minced garlic and diced zucchini. Cook for another minute.

Step 4: Combine the Filling and Simmer

Return the browned ground turkey to the skillet with the vegetables.
Add 1 cup of chicken broth, tomato paste, dried thyme, salt, pepper, cayenne pepper, and the bay leaf.
Stir everything together and simmer for 5 minutes so the flavors can combine.
Fold in the thawed peas and corn. Remove the skillet from the heat and discard the bay leaf.

Step 5: Assemble the Shepherd’s Pie

Spread the turkey and vegetable mixture into an even layer in the skillet.
Carefully spread the mashed potatoes over the filling, covering it completely.
Use a fork to create decorative swirls across the potato topping. These textured ridges help give the finished casserole an appealing appearance.

Step 6: Bake Until Golden

Place the skillet in the top third of the preheated oven.
Bake for 25 minutes, until the mashed potato topping is golden brown.
Remove the shepherd’s pie from the oven and let it rest for 10–15 minutes before serving. This resting time helps the layers set and makes it easier to portion.

Pro Tips for Easy Preparation

• Use a cast iron skillet: It allows you to cook the filling on the stovetop and transfer the same pan directly to the oven, reducing cleanup.
• Make fluffy mashed potatoes: An immersion blender can be used to mash the potatoes directly in the pot.
• Prepare vegetables quickly: A food processor can help pulse the vegetables into uniform pieces.
• Plan ahead: Since the casserole freezes well before baking, you can prepare it in advance and bake it when needed.

Adjust the Vegetables

The filling already includes carrots, zucchini, bell pepper, peas, and corn. You can adjust the vegetable proportions while keeping the overall filling combination similar.

Adjust the Seasoning
