Ingredients

For the sweet potatoes:

• 1 tablespoon olive oil
• ½ teaspoon salt

For the lentil sloppy joe filling:

• 1 tablespoon olive oil
• 1 medium yellow onion, diced
• 1 green bell pepper, diced
• 3 cloves garlic, minced
• 1 cup brown or green lentils, rinsed
• 2 cups vegetable broth (or water)
• 1 can (15 ounces) tomato sauce
• 2 tablespoons tomato paste
• 2 tablespoons maple syrup (or brown sugar)
• 2 tablespoons apple cider vinegar
• 1 tablespoon Worcestershire sauce (use vegan if needed)
• 1 teaspoon smoked paprika
• 1 teaspoon chili powder
• ½ teaspoon mustard powder
• ½ teaspoon salt, plus more to taste
• ¼ teaspoon black pepper

Optional toppings:

• Chopped fresh parsley
• Sliced green onions
• Vegan sour cream or plain yogurt
• Pickled jalapeños

Optional Substitutions

• Sweet Potatoes: Can substitute with regular baked potatoes or halved bell peppers for a lower-carb option.
• Lentils: Red lentils will cook faster but become mushy; use brown or green for best texture.
• Tomato Sauce: Use crushed tomatoes or diced tomatoes blended smooth. Adjust liquid as needed.
• Maple Syrup: Brown sugar, honey, or agave nectar all work well.
• Worcestershire Sauce: Soy sauce or tamari plus a splash of vinegar can replace it for a vegan version.
• Smoked Paprika: Regular paprika plus a pinch of liquid smoke will add a similar flavor.
• Vegetable Broth: Water with a bouillon cube or just plain water (add a bit more salt).
• Bell Pepper: Substitute with diced carrot or celery for a different flavor profile.

Instructions

1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or foil.
2. Prick each sweet potato several times with a fork. Rub with 1 tablespoon olive oil and sprinkle with ½ teaspoon salt. Place on prepared baking sheet.
3. Roast sweet potatoes for 40-50 minutes, until tender when pierced with a knife. Time depends on size; start checking at 35 minutes.
4. While potatoes roast, make the filling. Heat 1 tablespoon olive oil in a large skillet or pot over medium heat.
5. Add onion and bell pepper, cook 5-7 minutes until softened. Add garlic and cook 1 minute more.
6. Stir in lentils, vegetable broth, tomato sauce, tomato paste, maple syrup, apple cider vinegar, Worcestershire sauce, smoked paprika, chili powder, mustard powder, salt, and pepper. Stir well.
7. Bring to a boil, then reduce heat to low. Cover and simmer for 20-25 minutes, until lentils are tender and most liquid is absorbed. Stir occasionally. If too thick, add a splash of water; if too thin, uncover and simmer a few extra minutes.
8. Taste filling and adjust seasonings as desired. Add more salt, maple syrup, or vinegar to balance flavors.
9. Once sweet potatoes are done, let them cool slightly. Slice each potato open lengthwise and fluff the insides lightly with a fork.
10. Spoon generous amounts of lentil sloppy joe filling over each potato. Add optional toppings like parsley, green onions, or a dollop of vegan sour cream.
11. Serve immediately, or store components separately for later.

Pro Tips

• Choose uniformly sized sweet potatoes so they finish cooking at the same time.
• Don't skip pricking the potatoes – it allows steam to escape and prevents bursting.
• For extra crispy skins, rub with oil and roast directly on the oven rack, placing a baking sheet on the rack below to catch drips.
• Toast the lentils lightly in the dry pan for 1-2 minutes before adding liquid for a nuttier flavor.
• Adjust liquid as needed – different lentils absorb liquid differently, so check at 20 minutes and add broth if dry.
• Make the filling ahead – it keeps well in the fridge for up to 5 days and actually tastes better the next day.
• Double the filling to use over pasta, rice, or in wraps for extra meals.
• Use an instant pot – cook lentils on high pressure for 12 minutes with natural release, then add sauce and simmer.

Variations and Substitutions

• Spicy Version: Add ½ teaspoon cayenne pepper or a chopped chipotle pepper in adobo sauce to the filling.
• Stuffed Peppers: Instead of sweet potatoes, hollow out bell peppers and stuff with the lentil mixture; bake covered for 30 minutes.
• Add Greens: Stir in a handful of chopped spinach or kale at the end of cooking the filling until wilted.
• Cheddar Topping: Sprinkle shredded cheddar or vegan cheese over the stuffed potatoes and broil for 2 minutes until melted.
• Rice Bowl: Skip the sweet potato and serve the lentil sloppy joe over brown rice or quinoa for a different texture.
• Meaty Version: For non-vegetarians, substitute half the lentils with cooked ground turkey or beef.
• Lower Carb: Serve the lentil mixture over cauliflower rice or in lettuce wraps.
• Slow Cooker: Cook the filling in a slow cooker on low for 4-6 hours or high for 2-3 hours. Roast sweet potatoes separately.

Storage and Reheating

Fridge

• Store leftover sweet potatoes and filling separately in airtight containers. The filling will keep for up to 5 days; roasted sweet potatoes are best within 3 days.
• To store assembled potatoes, wrap tightly in foil or plastic wrap and refrigerate for up to 3 days.

Freezer

• The lentil sloppy joe filling freezes beautifully for up to 3 months. Thaw overnight in the refrigerator before reheating.
• Roasted sweet potatoes can be frozen, but texture may become slightly watery after thawing. For best results, freeze filling only and roast fresh sweet potatoes when ready to serve.

Reheating

• Microwave: Place assembled sweet potato on a microwave-safe plate and heat on high for 2-3 minutes, until hot.
• Oven: Reheat in a 350°F oven for 10-15 minutes, or until warmed through. For a crispy skin, unwrap if covered.
• Stovetop: Reheat filling in a skillet over medium heat, adding a splash of water if needed. Reheat sweet potatoes whole in microwave or oven.

FAQ

Can I use canned lentils instead? Yes, you can! Use 1½ cups cooked lentils (one 15-ounce can, drained and rinsed) and reduce the simmer time to 10 minutes, as they are already cooked. Adjust liquid accordingly, as you may need less broth.

Can I make this recipe gluten-free? Absolutely. Ensure your Worcestershire sauce is gluten-free (or use tamari), and all other ingredients are naturally gluten-free. Serve as directed.

Are these lentil stuffed sweet potatoes freezer-friendly? The filling freezes very well for up to 3 months. The sweet potatoes are best made fresh, but you can freeze the assembled dish if needed. Thaw overnight and reheat in the oven.

How can I make this recipe nut-free? This recipe is naturally nut-free. Just check your Worcestershire sauce and broth for any nut-based ingredients, though most are safe.

What can I use instead of maple syrup? Brown sugar, honey, agave, or even a mashed ripe banana can provide sweetness. Adjust to taste.

Can I cook the sweet potatoes in an air fryer? Yes! Air fry at 400°F for 35-40 minutes, depending on size. Prick and oil as instructed.

How do I prevent the filling from being too watery? Simmer uncovered during the last 5 minutes if too much liquid remains. Also, make sure to use the correct lentil type – brown or green hold their shape best.

What should I serve with these? A simple side salad, steamed green beans, or roasted broccoli pairs beautifully. The lentils and potatoes make a complete meal on their own.
