Ingredients
Servings
6
- 1 cup dry brown or green lentils, rinsed
- 2 ½ cups water or low-sodium vegetable broth
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 medium carrot, peeled and finely diced
- 1 celery stalk, finely diced
- 1 small red bell pepper, finely diced
- 1 cup finely chopped mushrooms (optional, for moisture and umami)
- 2 tablespoons ground flaxseed mixed with 6 tablespoons water (flax egg)
- 1/3 cup gluten-free oat flour or almond flour
- 1 teaspoon dried thyme
- 1 teaspoon smoked paprika
- ½ teaspoon ground cumin
- Salt and freshly ground black pepper, to taste
- 2 tablespoons tomato paste
- 2 tablespoons nutritional yeast (optional, for cheesy flavor)
- ½ cup tomato sauce or marinara
- 1 tablespoon maple syrup or agave nectar
- 1 teaspoon apple cider vinegar
- ½ teaspoon smoked paprika
- Pinch of salt
Instructions
-
Cook the lentils: In a medium pot, combine the rinsed lentils and water or vegetable broth. Bring to a boil, then reduce heat and simmer uncovered for 20-25 minutes until lentils are tender but not mushy. Drain any excess liquid and let cool slightly.
-
Prepare flax egg: In a small bowl, combine ground flaxseed with water. Stir and let rest for 5 minutes until gel-like.
-
Sauté vegetables: While lentils cook, heat a small non-stick skillet over medium heat (or use the air fryer with a pan accessory if available). Add a splash of water or vegetable broth and sauté onion, garlic, carrot, celery, bell pepper, and mushrooms until softened and fragrant, about 5 minutes. Remove from heat and let cool slightly.
-
Mix the loaf: In a large bowl, lightly mash cooked lentils with a fork or potato masher, leaving some texture. Add sautéed vegetables, flax egg, oat or almond flour, dried thyme, smoked paprika, cumin, tomato paste, nutritional yeast, salt, and pepper. Mix thoroughly until sticky enough to form a loaf. Add a bit more flour if mixture feels too wet.
-
Form loaf: Lightly grease a 7x3-inch loaf pan that fits your air fryer basket, or shape the loaf freeform on parchment paper or silicone mat inside the basket. Press mixture firmly and evenly into loaf shape.
-
Make glaze: In a small bowl, whisk together tomato sauce, maple syrup, apple cider vinegar, smoked paprika, and salt until smooth. Brush half the glaze evenly over the top of the loaf.
-
Air fry loaf: Preheat air fryer to 350°F (175°C) if needed. Place loaf in basket and cook for 20-25 minutes. Halfway through, carefully brush remaining glaze for a glossy finish.
-
Check doneness: The loaf should be firm, lightly browned on top and edges. If needed, air fry another 3-5 minutes for extra crispness.
-
Cool and serve: Remove from air fryer and cool in pan or on a rack for 10 minutes to set. Slice and serve warm with your favorite sides or fresh salad.
-
Meal prep & storage: Store leftovers airtight in the fridge up to 4 days. Slice before freezing for easy meals later.

Air Fryer Model Notes
This vegan lentil and vegetable loaf is easy to make but air fryer performance varies by model. Here are key considerations for best results:
- Basket Size & Shape: Ensure your air fryer basket can fit a 7x3 inch loaf pan or freeform loaf. Smaller baskets may require dividing the mixture or shaping smaller loaves for even cooking.
- Temperature Accuracy: Air fryer heat can vary. Monitor the loaf closely the first time you make it and adjust cooking time slightly to avoid over- or under-cooking.
- Air Circulation & Crispness: Models with better airflow around foods create more even crispness. If airflow is limited, you may need to rotate or flip the loaf or extend cooking time.
- Accessories: Using small pans or silicone mats helps shape the loaf and prevent sticking without blocking airflow. Avoid tightly covering the loaf, which hinders crisping.
- Preheating: Preheat if your model recommends it. Some newer air fryers heat quickly and allow placing food immediately, which can reduce drying.
Following these tips ensures a moist, flavorful loaf with a crispy exterior, tailored to your specific air fryer.
Crispiness Control
For the ideal balance of a crispy exterior and moist interior on your Vegan Lentil and Vegetable Loaf, try these air fryer crispiness tips:
- Temperature & Time: Cooking at 350°F (175°C) crisps the crust while cooking through evenly. Extend cooking by 3-5 minutes for a crunchier crust, watching to prevent drying.
- Glaze Use: Brush the tomato glaze halfway through and again near the end for a shiny, flavorful crust. Avoid thick or early application to preserve crispness.
- Loaf Shape: Form a loaf that fits well in your air fryer basket to allow airflow around the sides. A slightly thinner loaf crisps better but avoid making it too thin to prevent dryness.
- Extra Crisping: For more crunch, after initial cook, increase temperature to 360°F (182°C) for 2-3 minutes, monitoring closely to avoid overcooking.
- Resting: Let the loaf rest 10 minutes after cooking to firm the crust for easier slicing without crumbling.
These methods enhance the loaf’s gluten-free, low-fat, savory profile while delivering comforting, crisp texture—all ready in under 30 minutes.
Reheat In The Air Fryer
Reheat your vegan lentil loaf in the air fryer to restore its crisp crust and warm, tender interior. Follow these tips:
- Preheat: Warm your air fryer to 325°F (160°C) for 3-5 minutes to ensure even heating without drying.
- Reheat from Refrigerator: Place slices or entire loaf in the basket (lined with parchment if desired). Heat 6-8 minutes, flipping halfway for even warmth and crispness.
- Reheat from Frozen: If thawed overnight, reheat as above. To reheat frozen slices directly, cook 10-12 minutes, checking midway to avoid burning.
- Glaze Protection: Cover loaf loosely with foil during first half of reheating to protect glaze, then uncover for last 2-3 minutes to caramelize glaze.
- Space Slices: Leave room between slices to allow air circulation and prevent steaming.
- Safety: Heat until internal temperature reaches 165°F (74°C) for safe, delicious eating.
This reheating method keeps your loaf moist, flavorful, and crisp—ideal for leftovers or meal prep.
