How to Make the Best Big Mouth Spicy Veggie Burgers

Sweet potato and quinoa burgers that pack serious flavor and substance! These spicy veggie burgers are a delicious plant-based option loaded with nutritious ingredients that make them satisfying enough for any meal.

What Makes These Burgers Special

These aren’t your ordinary veggie burgers. The combination of sweet potato and quinoa creates a hearty texture that actually mimics ground meat, while black beans add protein and fiber. The sriracha and cumin bring heat and depth, making every bite exciting.

The Perfect Topping Strategy

The true magic happens with the caramelized red onions and goat cheese. While the burgers are wholesome and flavorful on their own, these toppings elevate the entire sandwich into something truly memorable. The sweetness of the caramelized onions balances the spicy burger perfectly, and the tangy goat cheese adds a sophisticated finish.
