Fajita-Stuffed Sweet Potatoes with Sizzling Peppers and Beef

Sweet potatoes are my go-to for quick, nutritious dinners on busy nights.

They work for any meal—breakfast, lunch, dinner, or snacks—especially when the fridge is low. If I have a stash of sweet potatoes, I can always make something healthy, filling, and delicious. Leftover roasted sweet potato smeared with peanut butter makes a perfect post-hike snack or a midday pick-me-up. Hi, I’m Chelsea, and I’m a little obsessed with sweet potatoes.

Quick clarification: these are sweet potatoes, not yams. In the U.S. the words are often used interchangeably in grocery stores, but true yams are a different, much larger tuber native to Africa. Most of what you buy labeled “yams” in American stores are actually sweet potatoes.

There are many varieties of sweet potatoes—Jewel, Garnet, Hannah, Japanese, Purple, and more—often all labeled as “yams.” My favorite for roasting and stuffing is the Garnet: they have creamy, sweet, deep orange flesh that roasts beautifully.

When selecting sweet potatoes, choose ones that are similar in size so they cook evenly. Short, plump potatoes are ideal because they give you more surface area for toppings—more filling space equals more satisfaction.

You can microwave sweet potatoes in a pinch (rinse, poke with a fork, and microwave 6–8 minutes until tender), but roasting gives the best texture and flavor. Microwaved potatoes may cook unevenly, and I prefer the caramelized, creamy texture of roasted sweet potatoes.

Roasting time depends on size: smaller potatoes may be done in about 30 minutes, while larger ones can take up to an hour. For very large potatoes, halve them lengthwise to speed cooking. My husband’s favorite shortcut is 4 minutes in the microwave followed by 25 minutes in the oven—fast but still nicely roasted.

Once roasted, load them with vegetables, beans or meat, top with cheese, and broil briefly for a bubbly finish. Finish with fresh additions like sliced avocado, salsa, or sour cream after broiling for brightness and texture.

For these Fajita-Stuffed Sweet Potatoes I layer the fillings like this:

1. Roasted sweet potatoes mashed slightly with a pinch of salt, pepper, and a bit of butter. Seasoning the potato is essential for depth of flavor.
2. Black beans tossed with salsa and chopped cilantro for extra flavor. Pinto or kidney beans would work well too.
3. Sautéed onions and peppers seasoned with cumin and garlic—this is the fajita component. Add cooked chicken or steak if you prefer.
4. Shredded cheddar melted under the broiler until golden and bubbly.
5. Sliced avocado with salt and lime, plus cilantro and extra salsa—the fresh toppings brighten the dish. My husband skips these, but they’re highly recommended.

Plan ahead: pick up a few similar-sized sweet potatoes this weekend, roast them, and store them in the fridge for easy meals later in the week. If you have all the components, you can assemble fajita-style potatoes. If not, they’re great topped with steamed broccoli and cheese or whatever leftovers you have on hand. We eat loaded sweet potatoes at least once a week.

If you try a loaded sweet potato this week, take a photo and share it with me—I love seeing what you make on Instagram!

Ingredients

• 4 medium or 2 large sweet potatoes Garnet are my favorite variety*
• 2 bell peppers any color
• 1 small red onion
• 1/2 Tablespoon olive oil
• 1/4 teaspoon salt
• 1/4 teaspoon garlic powder
• 1/2 teaspoon cumin
• 1/4 teaspoon chili flakes optional, for heat
• 1 15- ounce can black beans drained
• 1/4 cup jarred salsa
• 1/8 teaspoon salt
• 1/4 cup roughly chopped cilantro
• 1/2 cup sharp cheddar shredded
• toppings like: sliced avocado salsa, cilantro, sour cream, etc.

Instructions

• 1. Preheat oven to 350°F. Place whole sweet potatoes on a parchment-lined sheet pan and bake 30–60 minutes depending on size. Potatoes are done when a knife slides easily into the center. For extra-large potatoes, cut them in half lengthwise and bake cut-side down.
• 2. While potatoes roast, slice onions and peppers. Sauté in olive oil over medium heat for 8–10 minutes, stirring occasionally. Add salt, garlic powder, cumin, and chili flakes, then remove from heat.
• 3. In a small bowl, combine drained black beans with salsa, salt, and chopped cilantro.
• 4. When potatoes are tender, remove from oven and cut down the middle, leaving the sides intact. Add a pinch of salt and pepper and a small pat of butter to each half, then mash slightly with a fork. Top with the bean mixture, sautéed peppers and onions, and shredded cheddar. Broil 3–5 minutes until the cheese melts and bubbles.
• 5. Finish with avocado, extra salsa, cilantro, or sour cream and serve immediately. These keep well refrigerated for several days and reheat easily in the microwave for a quick lunch or dinner.

Notes

*Choose 4 sweet potatoes of similar size so they cook evenly. You can bake the potatoes up to 5 days ahead and store them in the fridge. Reheat briefly in the microwave or warm them in the oven while the broiler preheats so the potatoes are hot when you assemble the toppings.
