• 1 tablespoon olive oil
• 1 small yellow onion, finely chopped
• 3 garlic cloves, minced
• 10 ounces fresh spinach, roughly chopped
• ½ teaspoon dried oregano
• ¼ teaspoon freshly ground black pepper
• ¼ teaspoon crushed red pepper flakes, optional
• ⅓ cup plain Greek yogurt
• ¾ cup crumbled feta cheese, divided
• ½ cup shredded mozzarella cheese
• 1 teaspoon finely grated lemon zest

• 2 tablespoons chopped chives or parsley
• Lemon wedges, optional

Instructions for Spinach and Feta Stuffed Sweet Potatoes

1. Prepare the oven and potatoes.

Preheat the oven to 400°F (200°C). Line a rimmed baking sheet with parchment paper.

Scrub the sweet potatoes and dry thoroughly. Prick each one several times with a fork, rub with the olive oil, and sprinkle with salt and pepper.

2. Roast until completely tender.

Arrange the potatoes on the baking sheet with space between them. Bake for 45–60 minutes, depending on size.

They are ready when a knife slides easily into the thickest part and the centers feel soft. Larger potatoes may need additional time.

3. Cook the onion and garlic.

While the potatoes roast, heat the remaining tablespoon of olive oil in a large skillet over medium heat.

Add the onion and cook for 5–6 minutes until softened. Stir in the garlic and cook for 30 seconds, taking care not to brown it.

4. Wilt the spinach.

Add the spinach in batches, stirring as each batch wilts. Add the oregano, black pepper, and optional red pepper flakes.

Continue cooking until the spinach is tender and visible moisture has evaporated. A wet filling can make the finished potatoes watery.

Remove the skillet from the heat and let the mixture cool for about 5 minutes.

5. Mix the filling.

Stir the Greek yogurt, ½ cup feta, and lemon zest into the slightly cooled spinach mixture.

Taste before adding salt, since feta already contributes plenty of seasoning. Reserve the remaining ¼ cup feta for the topping.

6. Open the sweet potatoes.

Let the baked potatoes cool just until comfortable to handle. Cut a lengthwise slit into each potato, leaving the bottom and ends intact.

Gently press the ends toward each other to open the centers. Fluff the orange flesh with a fork, keeping the skins whole.

For a wider opening, scoop out 1–2 tablespoons of flesh from each potato and fold it into the spinach filling.

7. Fill and top.

Divide the spinach mixture among the potatoes, gently tucking it into the openings.

Sprinkle with mozzarella and the reserved feta. Return the potatoes to the baking sheet.

8. Bake again.

Bake at 400°F (200°C) for 10–15 minutes, until the filling is hot and the mozzarella has melted.

For more golden color, broil for 1–2 minutes, watching constantly. Use a broiler-safe tray and keep exposed parchment away from the heating element.

9. Garnish and serve.

Rest for 3 minutes, then scatter with chives or parsley. Serve warm with optional lemon wedges.

Tips for Spinach and Feta Stuffed Sweet Potatoes

• Choose similar-sized potatoes. They will finish roasting at approximately the same time.
• Roast without foil. This allows the skins to develop a more roasted texture.
• Cook off spinach moisture. The filling should be creamy rather than watery.
• Cool slightly before adding yogurt. This helps it combine smoothly.
• Use both cheeses for different textures. Feta stays crumbly, while mozzarella creates the melted topping.
• Season after adding feta. Taste first to avoid an overly salty filling.

Easy Variations For Spinach and Feta Stuffed Sweet Potatoes

Add chickpeas: Fold 1 cup drained, rinsed chickpeas into the spinach mixture for a more substantial meal.

Add mushrooms: Sauté 8 ounces finely chopped mushrooms with the onion until their moisture evaporates.

Use sun-dried tomatoes: Stir in ¼ cup chopped, drained sun-dried tomatoes for extra savory flavor.

Swap the cheese: Use goat cheese in place of feta, or shredded cheddar instead of mozzarella.

Make it dairy-free: Use thick unsweetened plant-based yogurt and dairy-free cheeses suitable for baking.

Serving Suggestions for Spinach and Feta Stuffed Sweet Potatoes

Serve one stuffed potato per person with a cucumber and tomato salad, roasted broccoli, or green beans.

For a larger dinner, pair with lentils, grilled chicken, or baked fish. Smaller sweet potatoes also make a colorful side dish for a holiday table.

Make-Ahead Instructions

Roast the potatoes and prepare the spinach filling up to 2 days ahead. Cool and refrigerate separately in covered containers.

When ready to serve, split and fill the potatoes, add the cheese, and bake at 375°F (190°C) until hot throughout, approximately 25–35 minutes. Cover loosely if the tops brown before the centers are heated.

Storage and Reheating

Refrigerate leftovers within two hours in an airtight container and use within 3–4 days.

Reheat in a 350°F (175°C) oven, loosely covered, until the center reaches 165°F (74°C). Uncover near the end to refresh the topping.

You can also microwave individual portions in short intervals, although the skins will become softer.

Frequently Asked Questions For Spinach and Feta Stuffed Sweet Potatoes

Can I use frozen spinach?

Yes. Substitute one 10-ounce package of frozen chopped spinach. Thaw completely and squeeze very dry before adding it to the cooked onion and garlic. Heat through, then continue with the filling.

Can I microwave the sweet potatoes first?

Yes. Prick them, place on a microwave-safe plate, and microwave until tender, turning halfway through. Timing depends on size and microwave power. Transfer to a baking sheet, fill, and finish in the oven as directed.

Do I need to peel the potatoes?

No. The skins hold the filling together and can be eaten after thorough scrubbing and roasting.

Can I leave out the yogurt?

Yes. Replace it with ricotta for a similar creamy texture, or omit it for a less creamy filling.

Why is my filling watery?

The spinach likely retained too much moisture. Cook fresh spinach until the pan is nearly dry, or squeeze thawed frozen spinach thoroughly.

Can I use regular baking potatoes?

Yes. Russet potatoes work well, although the flavor will be less sweet. Roast until fully tender before filling.
