Ingredients
- 1 cup quinoa, rinsed
- 2 cups vegetable broth or water
- 2 cups butternut squash, peeled and diced
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 teaspoon olive oil
- 1 teaspoon dried thyme
- 1 teaspoon salt, adjust to taste
- 1/2 teaspoon black pepper
- 1 cup shredded cheese (cheddar or mozzarella, optional)
- Fresh parsley for garnish (optional)
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C).
- Cook Quinoa: In a medium saucepan, bring the vegetable broth or water to a boil. Add the rinsed quinoa, reduce heat to low, cover, and simmer for about 15 minutes or until the quinoa is fluffy and the liquid is absorbed.
- Roast Butternut Squash: On a baking sheet, toss the diced butternut squash with olive oil, thyme, salt, and pepper. Roast in the preheated oven for about 20-25 minutes, or until tender and slightly caramelized.
- Sauté Aromatics: In a skillet, heat a little olive oil over medium heat. Add the chopped onion and garlic, sautéing until softened and fragrant.
- Combine Ingredients: In a large bowl, mix the cooked quinoa, roasted butternut squash, sautéed onions and garlic, and half of the shredded cheese (if using). Stir well to combine.
- Transfer to Baking Dish: Pour the mixture into a greased baking dish and spread evenly. Top with the remaining cheese.
- Bake: Bake in the oven for 20-25 minutes, or until the cheese is melted and bubbly.
- Serve: Garnish with fresh parsley if desired, and serve warm.
Cook’s tips
- Rinse quinoa thoroughly before cooking to remove its natural bitterness.
- Roast the butternut squash until it’s caramelized at the edges for extra sweetness and depth.
- Let the casserole rest for 10 minutes after baking to allow it to set and make serving easier.
- For a golden, crispy top, switch on the broiler for the last 2 minutes of baking.
- Use a mix of cheeses (like cheddar and mozzarella) for a richer, more complex flavor.
Substitutions
- Use sweet potato instead of butternut squash for a similar texture and taste.
- Substitute vegetable broth with chicken broth if you're not vegetarian.
- Replace cheese with nutritional yeast for a dairy-free, vegan-friendly version.
- Use any small pasta (like orzo) instead of quinoa if you prefer a more traditional casserole.
- Swap dried thyme with fresh thyme, using about 1 tablespoon of fresh for 1 teaspoon dried.
Storage & reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven at 350°F (175°C) for 10-15 minutes, or microwave individual portions until warmed through.
FAQ
Can I prepare this casserole ahead of time?
Yes, you can assemble the casserole completely (without baking) and refrigerate it for up to 24 hours. When ready to serve, bake as directed, adding a few extra minutes to the cooking time since it starts cold.
Can I freeze this casserole?
Absolutely. After baking and cooling, wrap the casserole tightly in foil and freeze for up to 3 months. Thaw overnight in the fridge, then reheat in the oven until hot and bubbly.
Is this recipe gluten-free?
Yes, quinoa is naturally gluten-free. However, be sure to check your vegetable broth and cheese (if using) for any hidden gluten ingredients.
Can I add other vegetables to this dish?
Definitely. Mushrooms, spinach, or bell peppers would all work well. Just sauté them with the onions and garlic, or roast them alongside the squash, and adjust seasoning accordingly.
