Barbecued Tempeh

Cubed tempeh sauteed with onions, garlic, and a warm spice blend, then baked for an hour in a tangy homemade barbecue sauce built on molasses, tomato paste, dry mustard, and apple cider vinegar. This is vegetarian barbecue that actually delivers on flavor and texture.

Tempeh is the right plant protein for barbecue treatment. Its firm, nutty texture holds up to the long bake without falling apart, and its slightly fermented flavor pairs naturally with the tangy, smoky sauce. Tofu would turn to mush in this recipe. Tempeh gets better.

The spice sautee sets the foundation. Fennel, coriander, cumin, chili powder, and cayenne cooked with onions and garlic for a few minutes bloom the spices and build an aromatic base that the sauce intensifies during baking. The green pepper goes in here too, adding a vegetal crunch that survives the oven.

The sauce is whisked together separately: tamari, lemon juice, molasses, cider vinegar, dry mustard, tomato paste, water, and hot sauce. That combination hits every flavor note: salty, sour, sweet, bitter, and spicy. Thirty minutes covered lets the tempeh absorb the sauce. Thirty minutes uncovered reduces and concentrates it into a thick, sticky glaze.

Pro Tips

• Stir frequently during the uncovered baking phase. The molasses and tomato paste burn easily once the liquid reduces.
• Cut the tempeh into small cubes for maximum sauce absorption. Larger pieces stay bland in the center.
• The sauce should be thick and clingy when done. If it’s still watery after the full hour, bake uncovered for another 10 minutes.
• Serve over steamed rice to catch the extra sauce, or stuff into warm pita with coleslaw for a sandwich.

Variations

• Smoky version: Add a teaspoon of smoked paprika and a few drops of liquid smoke to the sauce.
• Pineapple barbecue: Stir in ½ cup of crushed pineapple with the sauce for a Hawaiian-style twist.
• Sheet pan dinner: Spread the sauced tempeh and vegetables on a sheet pan with sweet potato cubes for a one-pan meal.
