This loaded sweet potato dish turns basic tubers into an exciting feast bursting with deep flavors and contrasting textures. The smooth, velvety potato flesh works as the ideal base for the hearty mushroom-spinach mixture, while the feta sprinkle adds just enough tang to bring everything together wonderfully.

I whipped up these loaded sweet potatoes when some friends dropped by unexpectedly for dinner and I needed a meatless option. They were such a success that now I make them whenever I want to wow guests without being stuck in the kitchen all day.

Ingredients

  • Sweet potatoes: Go for medium ones with smooth, unscratched skins for maximum taste and consistency
  • Olive oil: Grab a premium extra virgin variety for cooking to boost the overall taste
  • Onion and garlic: These basics create the essential taste foundation
  • Mushrooms: Regular white or brown ones add an earthiness and substantial bite
  • Fresh spinach: Gives a health kick and lovely green pop against the orange potato
  • Fresh rosemary: Delivers a woodsy, fragrant touch that goes brilliantly with sweet potatoes
  • Feta cheese: Offers a salty sharpness that balances the potato's natural sweetness
  • Walnuts: Not required but worth adding for crunch and nutty flavor
  • Lemon zest: Lifts the whole dish with gentle citrus hints
  • Red pepper flakes: Bring mild heat without going overboard

Step-by-Step Instructions

Cook the Sweet Potatoes:
Set your oven to 400°F. Scrub the sweet potatoes clean and poke them many times with a fork. These holes let steam escape so they won't burst while cooking. Arrange them on a paper-lined baking tray and cook for 45-60 minutes. The time changes based on how big they are, but they're done when a fork slides in easily. You'll notice the skin gets a bit shriveled and caramelized.
Make the Filling:
As the potatoes bake, warm olive oil in a big pan on medium. Toss in the chopped onions and cook until they soften and turn clear, around 3-4 minutes. Then add the minced garlic and cook just until you can smell it, about 60 seconds. Watch carefully since garlic burns fast and tastes awful when it does. Drop in the sliced mushrooms and let them cook for 5-7 minutes. This timing matters because well-cooked mushrooms first release their water and then start to brown, creating a rich flavor.
Mix in Greens and Flavors:
After the mushrooms have browned, throw in the fresh spinach. It might seem like too much at first but will quickly shrink down. Cook just until it's wilted, roughly 2-3 minutes. Mix in the chopped rosemary, salt, pepper, and red pepper flakes. The herbs should smell amazing and fill your kitchen with mouthwatering scents. Take the pan off the heat and stir in the crumbled feta and lemon zest while everything's still warm but not hot enough to completely melt the cheese.
Fill and Finish:
When potatoes are ready, let them cool enough to handle. Cut them open lengthwise, then gently push the ends to create an opening. Share the filling between all potatoes, piling it high. The bright orange potato against the dark green filling looks stunning on the plate. Sprinkle with chopped walnuts if you want and a little drizzle of olive oil before you serve.

The rosemary I use comes from my little windowsill herb garden. My grandma always told me rosemary brings memories back, and now I think about her showing me how to cook with fresh herbs from her garden when I was little every time I make this dish.

Make Ahead Options

You can easily prep these loaded sweet potatoes in advance. The potatoes can be baked and the filling made up to three days before you need them. Just keep them apart in sealed containers in the fridge. When you're ready to eat, warm the potatoes in a 350°F oven for about 15 minutes, heat up the filling in a pan or microwave, then put them together as shown. The flavors actually get better overnight, so they taste even nicer the next day.

Dietary Adaptations

This dish naturally fits gluten-free and vegetarian diets, but you can tweak it for other needs too. For a vegan version, just skip the feta or swap it for a plant-based option like cashew cheese or nutritional yeast. If you follow paleo, leave out the cheese and maybe add some cooked bacon bits or ground meat to the filling. Those avoiding dairy can use nutritional yeast for a similar savory kick without any milk products.

Serving Suggestions

These stuffed sweet potatoes work great as a standalone meal, but they also go well with other foods. For a light dinner, serve with a basic green salad and lemon dressing. If you're using them as a side, they taste amazing with roasted chicken or grilled fish. At brunch, try topping each portion with a poached egg for extra protein and a fancy look.

Frequently Asked Questions

→ Can I make these stuffed sweet potatoes ahead of time?

For sure! You can cook the potatoes and make the filling up to 2 days early. Keep them apart in the fridge, then warm up the potatoes, add the heated filling, and dig in. For the best flavor, sprinkle the feta on after warming everything up.

→ What can I substitute for feta cheese?

Soft goat cheese makes a great stand-in for feta and gives you that same tangy kick. If you don't do dairy, try firm tofu broken into bits with some nutritional yeast and lemon juice mixed in, or just leave the cheese out completely.

→ How do I know when the sweet potatoes are perfectly baked?

Your sweet potatoes are ready when they feel soft if you give them a gentle squeeze with an oven mitt on, and a knife slides right in without pushing. The skin might look a bit wrinkly, and you might see some sweet sticky stuff coming out from your fork holes.

→ Can I use different vegetables for the filling?

You bet! This dish works great with all sorts of veggies. Swap spinach for kale, use bell peppers instead of mushrooms, or throw in some roasted corn for extra sweetness. Just remember that different veggies need different cooking times.

→ Are these sweet potatoes suitable for vegans?

You can easily make this vegan by skipping the feta or swapping it for crumbled tofu mixed with nutritional yeast and a splash of lemon juice. Everything else in the recipe is already good to go for vegans.

→ What's the best way to reheat leftovers?

Warm up any leftovers in a 350°F oven for about 15 minutes until they're hot all the way through. You can use the microwave for 2-3 minutes too, but they won't come out quite as nice. Add some fresh feta and a little olive oil drizzle before eating to wake up the flavors.

Ingredients

→ Base

01 4 decent-sized sweet potatoes

→ Stuffing

02 2 tablespoons virgin olive oil
03 1 small diced onion
04 2 garlic cloves, finely chopped
05 2 cups sliced fresh mushrooms (cremini or button)
06 3 cups spinach leaves, fresh
07 1 tablespoon chopped fresh rosemary (or 1 teaspoon dried)
08 Black pepper and salt, as needed
09 1/2 cup crumbled feta cheese
10 1/4 cup walnuts, chopped (if you want)
11 1 teaspoon grated lemon peel
12 1/4 teaspoon hot pepper flakes (if you want)

Instructions

Step 01

Heat your oven to 200°C. Clean sweet potatoes well and poke them several times with a fork. Put them on a baking sheet lined with parchment and cook them for 45-60 minutes until they're soft when poked.

Step 02

Pour olive oil into a big skillet over medium heat. Throw in your diced onions and cook them for 3-4 minutes until soft. Toss in garlic and stir for another minute. Add the mushrooms and let them cook 5-7 minutes until they get juicy and start browning. Mix in the spinach and let it wilt for 2-3 minutes. Add rosemary, salt, pepper, and hot pepper flakes if you're using them. Cook one more minute, then turn off the heat and mix in the feta and lemon peel.

Step 03

Take the baked sweet potatoes out and let them cool a bit. Cut each one lengthwise but don't go all the way through. Push the ends toward each other to make a pocket. Stuff each potato with plenty of the mushroom, spinach and feta mix.

Step 04

Sprinkle chopped walnuts on top if you want them. Add a little more olive oil for extra taste and shine. Serve them while they're hot.
