01 - Preheat the oven to 340°F.
02 - Slice each tempeh block in half horizontally to create 4 thin steaks.
03 - In a saucepan, simmer the tempeh steaks in water for 10 minutes to remove bitterness. Drain and pat dry thoroughly.
04 - In a shallow dish, whisk together olive oil, soy sauce, lemon juice, garlic, rosemary, thyme, parsley, smoked paprika, black pepper, and salt until well combined.
05 - Place the tempeh steaks in the marinade, turning to coat evenly. Let marinate for at least 20 minutes, or up to 2 hours for deeper flavor penetration.
06 - Arrange tempeh steaks on a parchment-lined baking sheet. Brush with remaining marinade from the dish.
07 - Roast in the oven for 35 minutes, flipping halfway through and basting with reserved marinade, until golden brown and slightly crisp on edges.
08 - Garnish with chopped fresh parsley and serve immediately while hot.
