  • Acorn squash: 2 medium, halved and seeded
  • Olive oil: 2 tbsp, for brushing
  • Salt: ½ tsp
  • Black pepper: ¼ tsp
  • Yellow onion: 1 medium, finely chopped
  • Garlic: 2 cloves, minced
  • Carrot: 1 medium, diced
  • Celery: 1 stalk, diced
  • Lentils: 1 cup cooked green or brown
  • Walnuts: ½ cup, coarsely chopped

  • Fresh parsley: 2 tbsp, chopped
  • Dried thyme: 1 tsp
  • Ground cumin: ½ tsp
  • Smoked paprika: ½ tsp
  • Salt: ½ tsp, for filling

  • Feta cheese or vegan alternative: 2 tbsp crumbled, optional, for garnish

Instructions

Prepare 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 onion and cook for 3 to 4 minutes until softened. Stir in garlic, carrot, and celery. Cook for another 5 minutes until vegetables are tender. Add 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 flavors to meld. Remove from heat.
Stuff & Bake:
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. Return to oven and bake for 10 to 12 minutes until heated through and slightly golden on top.
Garnish & Serve:
Garnish with feta cheese and fresh parsley if desired. Serve warm.
