Step 1: Preheat the Oven. Begin by preheating your oven to 350°F (175°C). This will ensure that your loaf bakes evenly.
Step 2: Sauté the Vegetables. In a large skillet, heat a splash of water or vegetable broth over medium heat. Add the diced onion, carrot, celery, and mushrooms. Sauté for about 5-7 minutes until the vegetables are softened and fragrant. Remove from heat and let cool slightly.
Step 3: Prepare the Lentil Mixture. In a mixing bowl, combine the cooked lentils, sautéed vegetables, tomato paste, liquid aminos, balsamic vinegar, oats, almond meal, dried oregano, ketchup, additional balsamic vinegar, and Dijon mustard. Mix well until everything is fully incorporated.
Step 4: Shape the Loaf. Transfer the mixture into a greased baking dish or loaf pan. Use a spatula to press the mixture down firmly and shape it into a loaf.
Step 5: Bake. Place the loaf in the preheated oven and bake for about 45-50 minutes, or until the top is golden brown and the edges look crispy.
Step 6: Cool and Serve. Once baked, remove the loaf from the oven and let it cool for about 10 minutes. This will help it hold its shape when slicing. Serve warm with your favorite sides or a drizzle of extra ketchup!
