- 3/4 cup low-sodium vegetable broth

Step-by-Step Recipe

- Prepare the sweet potato: Pierce it several times and microwave on high 5–8 minutes until very soft. Let cool slightly, peel, and mash with 1 teaspoon oil or butter and 2 tablespoons milk until smooth; season lightly with salt.
- Make the filling: Heat 1 teaspoon oil in a small skillet over medium heat. Add the chopped onion and diced carrot and cook 4–6 minutes until softened.
- Add minced garlic and sliced mushrooms; cook 3–4 minutes until mushrooms release their moisture and become tender.
- Stir in the tomato paste and cook 1 minute to deepen flavor.
- Add the cooked lentils, vegetable broth, soy sauce, and thyme. Simmer gently 5–7 minutes until flavors meld and liquid reduces slightly; taste and adjust seasoning. For a softer texture, mash some lentils with the back of a spoon or pulse briefly in a small blender.
- Assemble: Spoon the lentil-mushroom filling into a small ovenproof dish or keep in the skillet if oven-safe. Spread the sweet potato mash evenly over the top.
- Bake or heat through: Place in a 375°F oven for 12–15 minutes until hot throughout. For a lightly browned top, broil 1–2 minutes while watching closely. Serve warm, garnished with chopped parsley if desired.
