Equipment

  • Large mixing bowls
  • Baking sheets
  • 9×13 inch casserole dish
  • Large pot (for boiling potatoes)
  • Colander
  • Sharp knife and cutting board
  • Measuring cups and spoons
  • Mixing spoon and spatula
  • Medium saucepan

Instructions

  1. Prepare the Butternut Squash Casserole: Preheat your oven to 375°F (190°C). Toss the cubed butternut squash with olive oil, cinnamon, salt, and pepper. Spread evenly in a greased casserole dish.
  2. Make the topping: Mix oats, chopped pecans, and maple syrup in a small bowl. Sprinkle this mixture over the squash. Bake for 35-40 minutes until the squash is tender and the topping is golden brown.
  3. Cook the Mashed Potatoes: Peel and cube potatoes. Boil in salted water until tender, about 15-20 minutes. Drain well.
  4. Mash the potatoes: Add minced garlic, plant-based milk, vegan butter, rosemary, salt, and pepper. Mash until creamy and smooth. Keep warm.
  5. Roast the Brussels Sprouts: Toss halved Brussels sprouts with olive oil, maple syrup, smoked paprika, salt, and pepper.
  6. Roast on a baking sheet: Spread in a single layer and roast at 400°F (200°C) for 25-30 minutes, shaking the pan halfway through for even browning.
  7. Prepare the Quinoa Cranberry Salad: In a large bowl, combine cooked quinoa, dried cranberries, walnuts, fresh parsley, lemon juice, olive oil, salt, and pepper. Toss to combine.
  8. Make the Vegetarian Stuffing: Heat olive oil in a skillet over medium heat. Sauté onions and celery until soft, about 5-7 minutes.
  9. Combine stuffing: In a large bowl, mix bread cubes, sautéed vegetables, sage, thyme, salt, and pepper. Add vegetable broth gradually, stirring until the bread is moist but not soggy.
  10. Bake the stuffing: Transfer the mixture to a greased baking dish. Cover with foil and bake at 350°F (175°C) for 30 minutes. Remove foil and bake an additional 10 minutes for a crispy top.

Tips & Variations

For extra flavor in your mashed potatoes, roast the garlic before mashing to add a subtle sweetness.

Try adding dried cherries or apricots to the quinoa salad for a different fruity twist.

Use gluten-free bread in the stuffing if you are catering to gluten sensitivities.

Add toasted pumpkin seeds or sunflower seeds to salads or casseroles for a delightful crunch.
