Pesto Chicken Stuffed Portobellos

These Pesto Chicken Stuffed Portobellos are a low-carb, flavor-packed dinner that feels indulgent yet is incredibly wholesome. Large portobello mushroom caps are cleaned and roasted until tender, then filled with a savory mixture of shredded rotisserie chicken, vibrant homemade or store-bought basil pesto, wilted spinach, and sun-dried tomatoes. The filling is topped with a generous amount of melted mozzarella cheese that becomes golden and bubbly in the oven. The mushrooms release their earthy juices into the filling as they bake, creating a deliciously moist and savory result. This dish is easy to assemble, visually impressive, and provides a complete meal in one satisfying "bowl." It's perfect for anyone looking for a delicious gluten-free or keto-friendly dinner option.
