For the Casserole
• Vegetable or Chicken Broth (2 cups) – Acts as the flavorful base for cooking quinoa. Note: Use low-sodium to control saltiness.
• Uncooked Quinoa (1 cup, rinsed) – Provides a healthy, protein-rich grain. Important: Rinse to remove saponins, which can make it bitter.

• Broccoli Florets (1 lb) – Adds nutrients and a delightful texture to the dish. Tip: Roast until slightly crisp to maintain a nice bite.
• Carrots (3 medium, diced) – Brings natural sweetness and vibrant color to the sauce. Can replace with other vegetables like bell peppers if desired.
• Yellow Onion (1 small, finely diced) – Gives aroma and savory flavor to the casserole.
• Garlic (1 tsp, minced) – Enhances depth and richness in the dish.
• All-Purpose Flour (2 tbsp) – A thickener for the delicious cheese sauce.
• Non-Fat Milk (1 cup) – Provides creaminess to unify the sauce. Substitution: Use any milk you prefer, such as almond or soy.
• Plain Nonfat Greek Yogurt (1 cup) – Adds creaminess and a slight tang, enriching the casserole without excessive fat.
• Dried Oregano (1 tsp) & Cayenne Pepper (1/8 tsp) – These give a flavorful kick and heartiness to the dish.
• Cheddar Cheese (3/4 cup sharp, reserved for topping) – The primary cheese for rich flavor; melted and gooey.
• Mozzarella, Fontina, or Provolone Cheese (3/4 cup) – Offers that perfect stretch and creaminess. Option: Mix and match cheeses based on what you have.
• Cannellini Beans (1 can, drained and rinsed) – Provides added protein and heartiness to the dish.

Step‑by‑Step Instructions for Creamy Quinoa Broccoli and Cheese Casserole
Step 1: Cook the Quinoa
In a medium saucepan, bring 2 cups of vegetable or chicken broth to a boil. Add 1 cup of rinsed quinoa, reduce the heat to low, cover, and simmer for about 15 minutes, or until the liquid is absorbed and the quinoa is fluffy. Once cooked, remove from heat and let it sit covered for another 5 minutes before fluffing it with a fork.
Step 2: Preheat the Oven
While the quinoa cooks, preheat your oven to 400°F (200°C). Prepare a baking sheet and a medium casserole dish by spraying them lightly with nonstick cooking spray. This ensures your creamy quinoa broccoli and cheese casserole will come out easily after baking and will help achieve that golden crust.
Step 3: Roast the Broccoli
In a large bowl, toss 1 pound of broccoli florets with 2 tablespoons of olive oil, salt, and pepper. Spread the broccoli evenly on the prepared baking sheet and roast for about 15-20 minutes, until slightly crisp-tender and bright green. This roasting step enhances the flavor and ensures it holds its texture in the casserole.
Step 4: Sauté the Vegetables
In a large pot, heat 1 tablespoon of olive oil over medium heat. Sauté 1 small finely diced yellow onion, 3 diced carrots, and 1 teaspoon of minced garlic for about 5-7 minutes, or until they are softened and fragrant. Stir occasionally to prevent sticking, allowing the flavors to meld beautifully together in your creamy casserole base.
Step 5: Prepare the Cheese Sauce
Sprinkle 2 tablespoons of all-purpose flour over the sautéed vegetables and cook for an additional 1-2 minutes, stirring constantly. Gradually whisk in the remaining broth and 1 cup of non-fat milk, stirring until the mixture thickens slightly, approximately 3-5 minutes. Season the sauce with 1 teaspoon of dried oregano and 1/8 teaspoon of cayenne pepper for a flavorful kick.
Step 6: Combine Ingredients
Stir in the cooked quinoa, drained and rinsed cannellini beans, and roasted broccoli into the cheese sauce. Make sure everything is well combined and adjust seasoning with salt and pepper as needed. This hearty mixture forms the delicious foundation of your creamy quinoa broccoli and cheese casserole.
Step 7: Add Yogurt and Cheese
Remove the pot from heat and mix in 1 cup of plain nonfat Greek yogurt and 1 and 1/2 cups of your chosen cheese blend (like cheddar and mozzarella). Stir until the cheese melts into the sauce, creating that creamy goodness that will envelop the quinoa and vegetables. Then, transfer the mixture gently to the prepared casserole dish.
Step 8: Top and Bake
Sprinkle the remaining 3/4 cup of shredded cheese and breadcrumbs evenly over the top of the casserole. Bake in the preheated oven at 350°F (175°C) for about 15 minutes, or until the cheese is melted and bubbly. For that perfect golden crust, switch to broil for the last 3-4 minutes, keeping a close eye to avoid burning.
Step 9: Serve and Enjoy
Once baked, remove the casserole from the oven and let it rest for a few minutes before serving. This allows the creamy quinoa broccoli and cheese casserole to set slightly, making it easier to portion. Serve warm alongside a refreshing side salad for a complete and satisfying meal.
