  • 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
  • Lentils: 1 cup cooked green or brown lentils
  • Walnuts: ½ cup, coarsely 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

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