Ingredients

  • For the Squash: 2 medium acorn squash, halved and seeded, 2 tbsp olive oil, ½ tsp salt, ¼ tsp black pepper
  • For the Filling: 1 tbsp olive oil, 1 medium yellow onion (finely chopped), 2 cloves garlic (minced), 1 medium carrot (diced), 1 celery stalk (diced), 1 cup cooked green or brown lentils, ½ cup walnuts (coarsely chopped), ½ cup cooked quinoa or brown rice (optional), ¼ cup dried cranberries or raisins, 2 tbsp chopped fresh parsley, 1 tsp dried thyme, ½ tsp ground cumin, ½ tsp smoked paprika, ½ tsp salt, ¼ tsp black pepper
  • For Garnish: 2 tbsp crumbled feta cheese or vegan alternative (optional), 2 tbsp chopped fresh parsley

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 35–40 minutes until tender.
Prepare the Filling:
While squash roasts, heat 1 tbsp olive oil in a large skillet over medium heat. Add the onion and cook for 3–4 minutes until softened. Stir in the garlic, carrot, and celery. Cook another 5 minutes until vegetables are tender.
Combine Ingredients:
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, then remove from heat.
Stuff and Bake:
Remove squash from oven and turn cut side up. Gently scoop out some flesh to create a cavity (leave about ½ inch border). Chop the scooped flesh and stir into the filling. Fill each squash half generously with mixture. Return to oven and bake 10–12 minutes, until heated through and slightly golden.
Serve:
Garnish with feta cheese and fresh parsley if desired. Serve warm.
