Bake the Sweet Potatoes: Preheat your oven to 400°F (200°C). Pierce each sweet potato with a fork several times and place directly on the oven rack. Roast for 45–55 minutes, until soft and tender when poked with a fork.
Prepare the Filling: In a large skillet, heat olive oil over medium heat. Add the diced onion and sauté for 3–4 minutes, until fragrant and translucent.Add mixed vegetables and cook another 5 minutes, stirring occasionally.
Add Chicken and Seasonings: Stir in the diced chicken, chicken broth, garlic powder, thyme, salt, and pepper. Simmer gently for 5–7 minutes so the flavors come together and the mixture slightly thickens.
Make It Creamy: Remove from heat, stir in the blended cottage cheese, and mix until creamy and smooth. The filling should be thick enough to spoon easily but not dry.
Assemble and Serve: Slice each roasted sweet potato down the center lengthwise and gently fluff the interior with a fork. Spoon the creamy chicken filling into each potato, letting it overflow slightly for that cozy, rustic look.Garnish with a sprinkle of fresh thyme or herbs. Serve warm.
