Ingredients

  • Acorn squash: 2 medium, halved and seeded
  • Olive oil: 2 tbsp for squash + 1 tbsp for filling
  • Salt: ½ tsp for squash + ½ tsp for filling
  • Black pepper: ¼ tsp for squash + ¼ tsp for filling
  • Yellow onion: 1 medium, finely chopped
  • Garlic: 2 cloves, minced
  • Carrot: 1 medium, diced
  • Celery stalk: 1, diced
  • Cooked lentils: 1 cup (green or brown)
  • Walnuts: ½ cup, coarsely chopped
  • Cooked quinoa or brown rice (optional): ½ cup, for extra texture
  • Dried cranberries or raisins: ¼ cup
  • Fresh parsley: 2 tbsp for filling + 2 tbsp for garnish, chopped
  • Dried thyme: 1 tsp
  • Ground cumin: ½ tsp
  • Smoked paprika: ½ tsp
  • Feta cheese or vegan alternative (optional): 2 tbsp, crumbled, for garnish

Instructions

Prep the squash:
Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper. Brush the cut sides of the acorn squash halves with olive oil. Sprinkle with salt and pepper. Place cut side down on the prepared baking sheet and roast for 35 to 40 minutes, until tender.
Make the filling:
While the squash roasts, heat 1 tbsp olive oil in a large skillet over medium heat. Add the onion and cook for 3 to 4 minutes until softened. Stir in the garlic, carrot, and celery. Cook for another 5 minutes until vegetables are tender. Add the cooked lentils, walnuts, quinoa or rice (if using), dried cranberries, parsley, thyme, cumin, smoked paprika, salt, and pepper. Mix well and cook for 2 to 3 minutes, allowing the flavors to meld. Remove from heat.
Stuff the squash:
Remove squash from oven and turn cut side up. Gently scoop out some flesh to create a cavity, leaving about ½ inch border. Chop the scooped flesh and stir into the filling. Fill each squash half generously with the lentil-walnut mixture.
Bake & finish:
Return to oven and bake for 10 to 12 minutes, until heated through and slightly golden on top. Garnish with feta cheese and fresh parsley, if desired. Serve warm.
