20-Minute Spicy Sriracha Grilled Tofu Skewers
Tender cubes of extra-firm tofu are marinated in a bold blend of sriracha, soy sauce, and aromatic spices, then grilled to perfection with a beautifully seared exterior and smoky flavor. The marinade combines heat from sriracha with umami depth from soy sauce and warming notes of garlic, ginger, and black pepper. Perfect for summer barbecues, weeknight dinners, or as a protein-packed addition to grain bowls and salads. The longer marination time allows the tofu to absorb maximum flavor.

FAQ
Can I use a different type of tofu?
Extra-firm tofu works best as it holds its shape on skewers and absorbs marinade well. Firm tofu can work but may be more fragile during grilling.
What if I don't have skewers?
Cut tofu into larger slabs and grill directly on grates, or use a grill basket to prevent pieces from falling through.
How long will marinated tofu keep?
Marinated raw tofu keeps up to 24 hours refrigerated. Cooked tofu skewers keep 3 days refrigerated and can be reheated gently.
