Ingredients

  • Acorn squash: 2 medium, halved and seeded
  • Olive oil: 2 tbsp, plus 1 tbsp for filling
  • Salt: ½ tsp, plus ½ tsp in filling
  • Black pepper: ¼ tsp, plus ¼ tsp in 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 chopped, plus 2 tbsp for garnish
  • Dried thyme: 1 tsp
  • Ground cumin: ½ tsp
  • Smoked paprika: ½ tsp
  • Crumbled feta cheese or vegan alternative (optional): 2 tbsp, for garnish

Instructions

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