Phase 1: Cook the Quinoa

1. Rinse Quinoa: Place the 1 cup of uncooked quinoa in a fine-mesh sieve and rinse thoroughly under cold running water for at least 30 seconds, or until the water runs clear. Drain well.
2. Cook Quinoa: In a medium saucepan, combine the rinsed quinoa, 2 cups of water or vegetable broth, and 1 tablespoon of olive oil. Bring the mixture to a boil over medium-high heat.
3. Simmer: Once boiling, reduce the heat to low, cover the saucepan with a tight-fitting lid, and simmer for 15 minutes, or until all the liquid has been absorbed and the quinoa is tender. You should see tiny spirals (the germ) separating from the seeds.
4. Rest: Remove the saucepan from the heat and let it stand, covered, for 5 minutes. This allows the quinoa to finish steaming and become fluffy.
5. Fluff: Uncover the quinoa and fluff it gently with a fork. Set aside. You should have approximately 3-4 cups of cooked quinoa.

Phase 2: Prepare the Bake Mixture

1. Preheat Oven and Prepare Baking Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish or a similar 2-3 quart casserole dish.
2. Combine Ingredients: In a large mixing bowl, add the cooked quinoa.
3. Add Pesto: Add 3/4 cup to 1 cup of pesto to the quinoa. If you’re using the optional heavy cream or coconut milk for extra creaminess, mix it with the pesto before adding to the quinoa. Stir gently until the quinoa is evenly coated.
4. Incorporate Vegetables and Seasonings:

   • Add the halved cherry or grape tomatoes, fresh baby spinach (it will wilt down considerably), chopped sun-dried tomatoes (if using), chopped roasted red peppers (if using), and Kalamata olives (if using).
   • If you want extra garlic flavor, add the minced garlic now.
   • Stir in 1/2 teaspoon of salt (adjust based on your pesto’s saltiness), 1/4 teaspoon of black pepper, and a pinch of red pepper flakes (if desired).
   • Gently fold everything together until well combined. The spinach will seem like a lot, but it will cook down.

5. Optional Cheese in Mixture: If you like cheese throughout, you can stir in about 1/4 cup of the shredded mozzarella into the quinoa mixture at this stage.

Phase 3: Assemble and Bake

1. Transfer to Baking Dish: Pour the quinoa and vegetable mixture into the prepared baking dish, spreading it into an even layer.
2. Top with Cheese: Sprinkle the remaining shredded mozzarella cheese (about 3/4 cup if you added some to the mixture, or the full 1 cup if not) evenly over the top of the quinoa mixture. Then, sprinkle the 1/4 cup of grated Parmesan cheese over the mozzarella.
3. Bake: Place the baking dish in the preheated oven. Bake for 20-25 minutes, or until the casserole is heated through, the cheese is melted, bubbly, and lightly golden brown, and the edges are sizzling. The cherry tomatoes should be softened and slightly burst.
4. Rest Before Serving: Once baked, carefully remove the Pesto Quinoa Bake from the oven. Let it rest for 5-10 minutes before serving. This allows the bake to set slightly, making it easier to serve and preventing it from being too molten hot.
5. Garnish (Optional): Garnish with fresh basil leaves, a drizzle of extra pesto, or toasted pine nuts before serving, if desired.
