This Spicy Sweet Chili Tofu Udon Bowl brings together crispy tofu, tender vegetables, and silky noodles tossed in a sticky and satisfying sauce. It is my favorite answer when I crave something cozy yet vibrant for a weeknight dinner or a leisurely lunch. The combination of crunchy tofu and the sauce makes it especially delicious and comforting.

The combination of bold flavors and textures just works every single time. I first tried this when my best friend visited and it instantly became both of our go-to comfort meals.

The sweet chili sauce is my favorite—it ties everything together with its hint of garlic and heat I once made a double batch just for the sauce and kept it for dipping spring rolls It takes the whole bowl to the next level
