1. Preheat your oven to 375°F (190°C) and generously grease a 9×13 inch baking dish or similar size. Make sure you grease well because the maple syrup can make things sticky.
2. In a small bowl, whisk together olive oil, soy sauce, maple syrup, garlic powder, onion powder, salt, and pepper until well combined and emulsified. Taste it—it should be balanced between sweet, salty, and savory.
3. Arrange the seitan slices and peach slices in the prepared baking dish in a single layer if possible. A little overlap is fine, but you want most pieces exposed.
4. Pour the maple-soy glaze over the seitan and peaches, making sure everything is coated evenly. Use a spoon or your hands to toss it all around so everything is glossy.
5. Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 20 minutes. Don’t peek or you’ll let out the steam.
6. After 20 minutes, carefully remove the foil (watch out for hot steam!), increase the oven temperature to 425°F (220°C), and bake uncovered for an additional 10 minutes until the seitan is golden and the peaches are caramelized with some golden-brown edges.
7. Remove from oven and let rest for a couple minutes. The glaze will thicken slightly as it cools.
8. Garnish with fresh thyme leaves before serving. Serve hot over rice, quinoa, or with a simple side salad. Enjoy the sweet-savory magic!

This provides excellent plant-based protein from seitan with natural sweetness from peaches.

Notes:

• Seitan is wheat gluten—not gluten-free. Use tofu or tempeh for GF version.
• Ripe peaches are crucial—they should smell sweet and give slightly when pressed.
• Don’t skip the foil—it keeps everything moist during the first baking stage.
• Watch the second bake—don’t walk away or the maple syrup can burn.
• Fresh is best—frozen peaches work but drain them well first.

Storage Tips:

Store leftover baked seitan with peach covered in the fridge for up to 3 days. Reheat gently in a 350°F oven for about 10 minutes, adding a splash of water or vegetable broth if it looks dry. This doesn’t freeze well—the peaches get mushy and weird when thawed, and the texture suffers. This is best eaten fresh or within a few days of making.

Serving Suggestions:

• Over White or Brown Rice: Soaks up the delicious glaze perfectly
• With Quinoa: Adds more protein for a complete meal
• Alongside Arugula Salad: Peppery greens balance the sweetness
• With Roasted Vegetables: Makes a complete, colorful plate

Mix It Up (Recipe Variations):

Asian-Inspired Version: Add 1 tablespoon fresh grated ginger to the glaze and finish with sesame seeds and sliced green onions.

Balsamic Peach Seitan: Add 1 tablespoon balsamic vinegar to the glaze for tangy depth that cuts through sweetness.

Spicy Version: Add 1 teaspoon sriracha or red pepper flakes to the glaze for heat that balances the sweet peaches.

Nectarine or Plum Swap: Use nectarines or plums instead of peaches for slightly different but equally delicious flavor profiles.

What Makes This Recipe Special:

This baked seitan with peach showcases how plant-based cooking has evolved beyond simple meat substitutes into creative, seasonal dishes that celebrate produce. The technique of pairing stone fruits with savory proteins creates that irresistible sweet-savory combination while the two-stage baking method ensures everything stays moist before caramelizing. The maple-soy glaze provides that addictive sweet-salty-umami profile that makes this genuinely crave-worthy. It’s proof that plant-based main dishes can be exciting, beautiful, and satisfying when you use seasonal ingredients and proper technique.
