Marinate the Vegan Protein: Mix seitan with olive oil, cornstarch, smoked paprika, and cayenne. Let it rest 10 minutes while you feel fabulous.
Make the Sauce: Combine ketchup, maple syrup, soy sauce, vinegar, chili flakes, garlic, onion powder, and liquid smoke. Whisk like you mean it.
Sear the “Thighs”: Heat a grill pan. Add seitan pieces and cook 5 minutes per side until golden and slightly crisp.
Coat in Sauce: Pour your spicy BBQ sauce over the seitan. Stir until it’s sticky, glossy, and dangerously addictive.
Caramelize: Let it simmer 3–4 minutes to thicken. The aroma alone deserves an applause.
Serve & Slay: Garnish with herbs, squeeze a lemon, and pair with roasted veggies or corn on the cob.
