On the stove

1. Cook the Sweet Potatoes (Fast Method): Wrap the sweet potatoes in paper towels and microwave on high for 10 minutes. Carefully unwrap, pierce with a fork, rewrap, and microwave again for 14–15 minutes until soft.

1. Bake the Sweet Potatoes (Slow Method): Preheat oven to 220°C (430°F) and lightly spray a baking tray with nonstick spray. Arrange the sweet potatoes on the tray and roast for about 1 hour until tender, checking after 40 minutes.

1. Sauté the Vegetables: While the potatoes cook, heat olive oil in a skillet over medium-high heat. Add sliced onion and cook until soft, then toss in the garlic and bell peppers until fragrant.

1. Add Chicken and Spices: Stir in the sliced chicken breast, cumin, and paprika until everything is well coated. Cook for a few minutes, then mix in the black beans and remove from heat.

1. Prepare the Potato Shells: Let the cooked sweet potatoes cool slightly before slicing them in half lengthwise. Gently scoop out the flesh, leaving a thin wall inside each skin to hold the filling.

1. Mix the Filling: In a bowl, combine the scooped sweet potato flesh with the chicken fajita mixture. Add the lime juice and stir until the ingredients are evenly mixed and creamy.

1. Stuff and Bake: Place the potato skins back on the baking tray and fill them with the mixture. Sprinkle with shredded cheese and cilantro, then bake for 15–20 minutes until the tops are golden and bubbling.

1. Serve and Enjoy: Top with extra cilantro, avocado, salsa, and lime wedges before serving. Each stuffed potato is bursting with flavor and good for a quick, satisfying meal.

Balance the spice and richness of these Sweet Potatoes Fajitas with something fresh and surprising like Avocado Tomato Corn Salad. The sweet corn and creamy avocado bring a cool contrast to the smoky fajita filling, while the lime dressing ties it all together beautifully.

For something a little heartier, try Garlic Cheese Bread for dipping into any extra salsa or melted cheese that escapes from your stuffed potatoes. Or make it a real Tex-Mex inspired feast by serving Creamy Pumpkin and Spinach Soup with Crispy Bacon on the side. The velvety soup and salty bacon are the good cozy pairing for these bold, flavorful potatoes.

Kitchen tip

• Bake or microwave your sweet potatoes just until tender so they hold their shape when stuffed.
• Use smoked paprika for extra depth and that subtle fajita smokiness.
• Shred the chicken finely so it mixes evenly with the mashed sweet potato filling.
• Don't skip the lime juice, it brightens the entire dish and cuts through the richness.

Method

1. Wrap sweet potatoes in one piece of paper towel. Microwave on high settings for 10 minutes. Remove carefully from microwave and unwrap (being careful of the steam that will escape from inside the paper towels). Pierce all over with a fork, wrap again and microwave for a further 14-15 minutes until soft (if the centres are still a little hard, don't worry they will continue to cook in the oven later).
2. Preheat oven to 220°C | 430°F. Spray a baking tray/sheet with nonstick spray and arrange sweet potatoes the tray. Roast for one hour in the oven, or until soft (check them after 40 minutes, pierce with a fork, and continue roasting if needed).
3. While the sweet potatoes are cooking, add a small amount of oil to the pan; add the onions to a skillet/frying pan over medium-high heat. Once transparent (about 1-2 minutes), add the chicken, garlic and capsicum/peppers. Cook until the garlic is fragrant. Add in the seasonings and continue cooking until chicken is completely coated in the seasonings. Mix the beans through; take off heat and set aside
4. Remove the sweet potatoes from the oven; allow them to cool for about 5 minutes until they are just warm enough to handle (not until they're completely cold); and carefully slice them in half. Slice around the inside of the skin, leaving 1cm 'wall' around the inside of the skin. Slice small cubes into the flesh for easier removal. Scoop out the flesh and transfer it into a medium-sized mixing bowl. Set the skins aside.
5. Add the chicken fajita mixture to the flesh in the bowl; mix it through until completely combined. Stir in the lime juice.
6. Arrange the skins on the same baking tray/sheet, and stuff them with the fajita sweet potato mixture. Sprinkle with cheese and the coriander/cilantro leaves. Put them back into the oven for 15-20 minutes until cheese is bubbling and starting to brown (or place under the grill/broiler in the oven for golden, crispy cheese for 10 minutes).
7. Serve with any left over coriander/cilantro leaves, lime wedges, avocado pieces and smother in salsa dip.
