Instructions

Preheat your oven to 400 degrees F.
In a large bowl, toss the diced red bell pepper, zucchini, yellow squash, red onion, cherry tomatoes, and broccoli florets with 2 tablespoons olive oil, minced garlic, dried oregano, dried thyme, smoked paprika, salt, and black pepper until evenly coated.
Spread the seasoned vegetables in a single layer on a large baking sheet. Roast in the preheated oven for 25-30 minutes, stirring halfway through, until the vegetables are tender and lightly caramelized.
While the vegetables roast, rinse quinoa thoroughly under cold water in a fine mesh sieve to remove bitterness and ensure gluten-free safety.
In a medium saucepan, bring the vegetable broth 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 broth is absorbed. Remove from heat and let it sit covered for 5 minutes.
Reduce the oven temperature to 350 degrees F. Lightly grease a 9x13 inch (23x33 cm) casserole dish with 1 tablespoon olive oil.
Once vegetables are roasted, gently combine the quinoa and vegetables in a large bowl. If desired, stir in balsamic vinegar for a touch of tanginess.
Transfer the mixture into the prepared casserole dish, spreading evenly.
Bake uncovered in the 350 degrees F oven for 15 minutes to meld flavors and warm through.
Remove from oven and sprinkle fresh chopped parsley on top for garnish if desired.
Let the casserole cool for 5 minutes before serving. Enjoy warm as a wholesome main course or a hearty side dish.
Store leftovers covered in the refrigerator for up to 4 days or freeze for up to 2 months.

Tips

Allergen Overlap Note

Check every packaged ingredient for certified gluten-free status, especially spices, broths, sauces, seed products, and baking staples. Use clean prep surfaces, dedicated utensils, and fresh parchment or cookware when preparing family-style quinoa and roasted vegetable bake for someone with celiac disease.

Texture Expectations

The bake should be fluffy and moist rather than mushy, with roasted vegetables that keep their shape. Letting the quinoa sit covered before combining helps the grains separate cleanly in the casserole.

Dining With Non-GF Family Note

Bring the casserole to the table with a dedicated gluten-free serving spoon. If bread or pasta sides are served for other family members, place them away from the casserole dish and spoon.
