These roasted sweet potatoes are generously filled with a spicy chicken fajita mixture featuring tender chicken strips, sautéed bell peppers, and onions. After stuffing, they’re topped with melted cheddar cheese, creating a hearty and flavorful dish perfect for a satisfying meal. The combination of smoky spices, tender vegetables, and creamy toppings brings a rich Tex-Mex flair. Optional sour cream and avocado add a cool, fresh contrast to the warmth of the filling.
There's something about the moment a sweet potato splits open to reveal its warm, steaming flesh that makes me pause every time. I discovered this recipe on a weeknight when I had roasted sweet potatoes staring at me from the counter and leftover fajita spices calling from the cabinet. What started as improvisation became the kind of dinner I find myself craving now—hearty enough to satisfy, bright enough to feel fresh, and honestly, a little bit exciting for a Tuesday.
I made these for friends who claimed they didn't really eat sweet potatoes, and I watched their skepticism melt faster than the cheese on top. Something about loading their own stuffed potato, adding cilantro and avocado exactly how they wanted it, turned the whole thing into this relaxed, build-your-own moment. By the end of the meal, someone was already asking if I'd make them again next week.
Ingredients
- Medium sweet potatoes (4): Look for ones that are roughly the same size so they cook evenly; if one is significantly larger, it'll still be raw when the others are perfect.
- Olive oil (3 tablespoons total): Use a decent quality here since it's part of the flavor, not just the function.
- Boneless, skinless chicken breasts (2 large): Cutting them into bite-sized strips lets them cook quickly and absorb all that spice.
- Chili powder, smoked paprika, cumin (2 teaspoons, 1 teaspoon, 1 teaspoon): These three create the soul of the fajita flavor; don't skip or swap them out lightly.
- Garlic powder, onion powder, cayenne (1/2 teaspoon, 1/2 teaspoon, 1/4 teaspoon): The garlic and onion powder round out the spice blend, while cayenne adds heat only if you want it.
- Red and green bell peppers, yellow onion: The vegetables soften into the chicken and become almost creamy; thinly slicing them makes a difference in how they cook.
- Fresh lime juice: Squeeze it right over the hot filling so the acid brightens everything.
- Shredded cheddar or Monterey Jack (1 cup): Monterey Jack melts more smoothly, but either works beautifully.
- Fresh cilantro, sour cream, avocado: These are your finishing touches, so don't stress if you skip any of them.
Instructions
- Prep and roast the sweet potatoes:
- Preheat your oven to 400°F and prick each potato several times with a fork so steam can escape. Rub them generously with olive oil and salt, then spread them on a baking sheet and slide into the oven for 40 to 50 minutes, depending on size. You'll know they're done when a fork pierces the skin with almost no resistance.
- Build the fajita base:
- While the potatoes roast, heat 2 tablespoons olive oil in a large skillet over medium-high heat until it shimmers. Add your chicken strips and all the spices at once, stirring constantly for about 2 to 3 minutes so the spices coat every piece and the chicken starts to turn golden.
- Add the vegetables:
- Throw in your sliced peppers and onions, stirring frequently, and let them soften into the chicken for 5 to 7 minutes until everything is cooked through. Pour the lime juice over the top and toss everything together so the acid hits the hot filling and wakes it all up.
- Hollow and fill:
- Once the potatoes are cool enough to handle, slice each one lengthwise and gently fluff the insides with a fork, creating a little well for the filling. Generously stuff each potato with the warm chicken mixture, mounding it in so every bite has flavor.
- Top with cheese and melt:
- Sprinkle the shredded cheese evenly over each stuffed potato and return them to the oven for about 5 minutes, just long enough for the cheese to melt and get a little bubbly. Watch it so the cheese doesn't brown too much.
- Finish and serve:
- Remove the potatoes from the oven, add a pinch of cilantro, a dollop of sour cream, and sliced avocado if you're using them. Serve immediately while everything is still warm.
This became one of my go-to recipes the moment I realized it's the kind of food that brings people together without feeling fussy. Something about customizing your own plate with the toppings you want makes everyone feel a little special, and honestly, that's when food tastes best.
Why the Sweet Potato Base Works
Sweet potatoes are naturally sweet and creamy, which means they don't compete with the savory fajita spices—they actually complement them. The natural sweetness creates this unexpected harmony with the lime and chili heat, and their soft texture cradles the filling perfectly. I've tried this with regular potatoes and it's fine, but it's missing that subtle sweetness that makes this dish feel a little more interesting than it should.
Making It Your Own
The beautiful thing about this recipe is that it's a starting point, not a rule. Some nights I add roasted corn to the filling for sweetness, other times I throw in diced jalapeños if I'm feeling spicier. A friend of mine makes a vegetarian version with seasoned black beans and it's just as satisfying as the chicken version. The structure stays the same; the personality changes depending on what's in your kitchen and what you're craving.
Storage and Timing Tips
You can roast the sweet potatoes ahead of time and store them in the fridge for up to three days, then quickly reheat them and add the warm filling when you're ready to eat. The chicken fajita mixture also keeps well for a few days, which means you can make these throughout the week without repeating the whole cooking process. The only thing I wouldn't do ahead is add the cheese and melt it, since it's best melted fresh just before serving.
- If you're prepping for the week, keep the filling and potatoes separate until you're ready to assemble and heat.
- Sour cream and avocado should be added right before eating so they stay fresh and don't get weepy or brown.
- This dish pairs beautifully with a crisp lager or a cold glass of Chardonnay if you're looking to make it feel special.
This recipe has become my answer to the question of what to make when I want something that feels homemade and intentional but doesn't demand hours in the kitchen. It's one of those meals that reminds you why cooking for yourself or for people you care about is worth the effort.
