Stuffed sweet potatoes filled with sautéed spinach mushrooms and creamy feta always remind me of cozy fall dinners. This recipe gives simple vegetables a rich satisfying upgrade with a combination of earthy rosemary and tangy cheese for the ultimate comfort meal.
When I made this for my book club everyone wanted seconds before the discussion even started and now I make it whenever I crave something nourishing but not fussy
Ingredients
- Sweet potatoes: for a hearty naturally sweet base look for firm smooth tubers with deep orange flesh
- Olive oil: brings richness and helps everything sauté beautifully choose extra virgin for best flavor
- Onion and garlic: the classic foundation to build roundness and savoriness go for fresh juicy onion and plump garlic cloves
- Button or cremini mushrooms: add umami heartiness pick dry firm mushrooms with tight caps
- Fresh spinach: gives a pop of color and nutrients tender baby spinach works best
- Rosemary: brings earthy aromatic note use fresh sprigs and chop finely for best results
- Salt and black pepper: to season letting the vegetables shine use sea salt and fresh cracked pepper if you have them
- Feta cheese: for a creamy salty finish look for Greek feta in blocks for richer flavor and crumble yourself
- Lemon zest: adds brightness and lifts all the flavors use organic if possible
- Walnuts: for crunch and subtle bitterness toast them briefly for extra flavor
- Red pepper flakes (optional): for gentle heat use just a pinch to not overwhelm the other flavors
Step-by-Step Instructions
- Prepare and Bake Sweet Potatoes:
- Scrub sweet potatoes well and pierce each one several times with a fork. Place directly on a parchment-lined baking sheet and roast in a 200 degree Celsius oven for forty five to sixty minutes until fork tender and the skins begin to pull away at the edges. This step allows the natural sugars to caramelize for irresistible flavor.
- Sauté the Vegetables:
- Heat olive oil in a wide skillet over medium heat. Add diced onion and cook stirring often for about three to four minutes until soft translucent and fragrant. Add minced garlic and continue stirring constantly for one minute so it does not burn. Add sliced mushrooms and cook for five to seven minutes stirring occasionally until they release their juices and start to brown on the edges.
- Wilt the Spinach and Season:
- Add fresh spinach to the skillet in handfuls so it fits and stir until just wilted about two to three minutes. Sprinkle in chopped rosemary salt black pepper and if you want a gentle kick the red pepper flakes. Cook for one more minute to marry the flavors and then remove skillet from the heat.
- Finish the Filling:
- Immediately fold in crumbled feta cheese and lemon zest. Allow the warmth of the veggies to soften the feta only slightly but keep it distinct. Stir until just blended with streaks of creamy cheese visible in the mix.
- Stuff the Sweet Potatoes:
- Once the sweet potatoes have cooled slightly slice each open lengthwise down the center leaving the base attached so they hold together. Gently press the ends toward each other to make a pocket. Generously spoon the spinach mushroom feta mixture into each potato so it overflows a little.
- Garnish and Serve:
- Top stuffed sweet potatoes with chopped walnuts for crunch and an extra drizzle of olive oil for shine. Serve while piping hot for the best flavor and texture.

The feta cheese is hands down my favorite part its briny creamy flavor balances the sweet potato so perfectly. My kids call this their magic dinner because it just disappears from their plates.
Storage Tips
Let leftovers cool completely before storing. Place in an airtight container and refrigerate for up to three days. Reheat in the oven at 180 degrees Celsius wrapped loosely in foil for best texture or microwave if short on time.
Ingredient Substitutions
Swap fresh spinach for kale or Swiss chard if that is what you have. Use goat cheese in place of feta for a milder finish. Any type of mushroom works just keep the slices fairly uniform for even cooking.
Serving Suggestions
Serve alongside a crisp green salad for a light meal or as a side to grilled proteins. For extra heartiness spoon a dollop of Greek yogurt or a handful of pomegranate seeds over the top.

Cultural Context
Stuffed vegetables have deep roots in Mediterranean kitchens and combining sweet and savory elements like sweet potato and feta is a classic Greek-inspired twist. While this is not an old-world recipe the ingredients and approach tip their hat to these traditions.
