Ingredients

• 1 cup quinoa, uncooked – Provides a nutritious and protein-rich base for the casserole. Make sure to rinse it thoroughly before cooking to remove any saponins, which can impart a bitter taste.
• 2 cups vegetable broth – Used to cook the quinoa, adding flavor and moisture. You can also use chicken broth for a richer taste if you prefer. Low-sodium broth is recommended to control the salt content of the dish.
• 1 large head of broccoli, cut into florets (about 6 cups) – The star vegetable of the dish, broccoli adds a vibrant green color, earthy flavor, and a wealth of vitamins and fiber. Ensure florets are bite-sized for even cooking and enjoyment.
• 4 tablespoons unsalted butter – Forms the base of the roux for the cheese sauce, adding richness and flavor. Unsalted butter allows you to control the overall salt level of the casserole.
• 1/4 cup all-purpose flour – Used to thicken the cheese sauce, creating a smooth and creamy texture. For a gluten-free option, you can use a gluten-free all-purpose flour blend or cornstarch, though the texture might slightly differ.
• 3 cups milk – The liquid component of the cheese sauce, milk adds creaminess and body. Whole milk will result in the richest sauce, but you can use 2% or even skim milk for a lighter version. Consider using warmed milk for smoother sauce creation.
• 8 ounces cream cheese, softened – Adds tanginess, creaminess, and a luxurious texture to the cheese sauce. Softened cream cheese will incorporate more smoothly into the sauce, preventing lumps.
• 4 cups shredded cheddar cheese – The main cheese component, cheddar provides a sharp and savory flavor that complements the broccoli and quinoa beautifully. Sharp cheddar will give a more pronounced cheesy taste, while mild cheddar offers a smoother flavor. Pre-shredded cheese is convenient, but shredding your own from a block will melt more smoothly and often has better flavor.
• 1 cup shredded Monterey Jack cheese – Adds a mild, buttery flavor and excellent melting properties, creating a gooey and stretchy cheese pull. Monterey Jack blends well with cheddar and adds a different dimension to the cheesy flavor profile.
• 1/2 cup grated Parmesan cheese – Provides a salty, nutty, and umami-rich flavor to the casserole, enhancing the overall depth of taste. Parmesan also adds a nice browned crust when baked on top. Use freshly grated Parmesan for the best flavor.
• 1 teaspoon garlic powder – Adds a savory and aromatic garlic flavor that enhances the cheese sauce and complements the broccoli. Garlic powder is convenient, but you can also use fresh minced garlic sautéed in butter for a more intense garlic flavor.
• 1 teaspoon onion powder – Adds a subtle onion flavor that rounds out the savory notes of the casserole. Onion powder blends seamlessly into the sauce, but finely diced and sautéed onion can be used for a more pronounced onion flavor.
• 1/2 teaspoon salt – Enhances the flavors of all the ingredients and balances the richness of the cheese sauce. Adjust salt to taste, considering the saltiness of the cheeses and broth used.
• 1/4 teaspoon black pepper – Adds a touch of spice and complexity to the casserole. Freshly ground black pepper is recommended for the best flavor.
• Optional: 1/4 cup breadcrumbs (panko or regular) – Provides a crispy topping for the casserole. Panko breadcrumbs offer a lighter and crispier texture than regular breadcrumbs. Toss breadcrumbs with a little melted butter or olive oil for extra browning and flavor.

Instructions

1. Preheat your oven to 375°F (190°C). Preheating ensures the oven is at the correct temperature when you place the casserole in, promoting even cooking and browning. Make sure your oven is properly calibrated for accurate temperature.
2. Cook the quinoa: Rinse the quinoa thoroughly in a fine-mesh sieve under cold water. This step is crucial to remove saponins, naturally occurring compounds that can make quinoa taste bitter. Place the rinsed quinoa and vegetable broth in a medium saucepan. Bring to a boil, then reduce heat to low, cover, and simmer for 15-20 minutes, or until all the liquid is absorbed and the quinoa is fluffy. Fluff with a fork and set aside. Properly cooked quinoa should be tender and slightly chewy.
3. Steam or blanch the broccoli: Steam the broccoli florets until they are tender-crisp, about 5-7 minutes. Alternatively, blanch them by briefly boiling them in salted water for 2-3 minutes and then immediately plunging them into ice water to stop the cooking process. This helps retain their vibrant green color and prevents them from becoming mushy in the casserole. Drain the broccoli well and set aside. Overcooked broccoli will become soft and lose its texture and color in the casserole.
4. Prepare the cheese sauce: In a large saucepan over medium heat, melt the butter. Once melted, whisk in the flour and cook for 1-2 minutes, stirring constantly. This creates a roux, which is the foundation of the cheese sauce. Cooking the roux for a minute or two removes the raw flour taste and ensures a smooth sauce. Gradually whisk in the milk, a little at a time, ensuring each addition is fully incorporated before adding more. This prevents lumps from forming and creates a smooth, creamy sauce. Continue whisking until the sauce thickens slightly, about 5-7 minutes. The sauce should be thick enough to coat the back of a spoon.
5. Add the cheese and seasonings: Reduce the heat to low. Stir in the softened cream cheese until it is completely melted and smooth. Then, add the shredded cheddar cheese, Monterey Jack cheese, Parmesan cheese, garlic powder, onion powder, salt, and pepper. Stir until all the cheeses are melted and the sauce is smooth and creamy. Taste and adjust seasonings as needed. Seasoning is crucial at this stage; ensure the cheese sauce is flavorful before adding the quinoa and broccoli.
6. Combine ingredients: In a large bowl, gently combine the cooked quinoa, steamed broccoli florets, and cheese sauce. Stir until everything is evenly coated. Be careful not to overmix, which could break down the broccoli.
7. Transfer to a baking dish: Pour the mixture into a greased 9×13 inch baking dish or a similar sized casserole dish. Greasing prevents the casserole from sticking to the dish and makes serving easier.
8. Add topping (optional): If desired, sprinkle breadcrumbs evenly over the top of the casserole. This will add a crispy texture to the finished dish.
9. Bake: Bake in the preheated oven for 20-25 minutes, or until the casserole is heated through, bubbly, and the topping (if used) is golden brown. The baking time may vary slightly depending on your oven. The casserole is ready when it is heated through and the cheese is melted and bubbly.
10. Rest and Serve: Let the casserole rest for 5-10 minutes before serving. This allows it to set slightly and makes it easier to serve. Resting also allows the flavors to meld together even further. Serve hot and enjoy!

Additional Tips

1. Don’t overcook the quinoa: Overcooked quinoa can become mushy and lose its pleasant texture. Follow the cooking instructions carefully and check for doneness after 15 minutes. It should be tender and slightly chewy.
2. Customize your cheese blend: Feel free to experiment with different cheeses to create your own flavor profile. Gruyere, fontina, pepper jack, or even a smoked gouda would be delicious additions or substitutions.
3. Add more vegetables: Boost the nutritional value and flavor by adding other vegetables to the casserole. Sautéed onions, mushrooms, bell peppers, or spinach would all work well. Roast root vegetables like carrots or sweet potatoes for a sweeter note.
4. Spice it up: For a little kick, add a pinch of red pepper flakes to the cheese sauce or use pepper jack cheese. A dash of hot sauce served on the side is also a great option for those who like a bit of heat.
5. Make it ahead of time: Assemble the casserole ahead of time and store it, covered, in the refrigerator for up to 24 hours. Bake it just before serving, adding a few extra minutes to the baking time if needed. This is perfect for meal prepping or entertaining.
6. Freeze for later: Baked or unbaked casserole can be frozen for up to 3 months. For best results, freeze before baking. Thaw overnight in the refrigerator before baking as directed. Baked casserole can be reheated directly from frozen in a low oven, covered, until heated through.
7. Ensure broccoli is tender-crisp: Overcooked broccoli will become mushy in the casserole. Steaming or blanching it until tender-crisp ensures it retains some texture and doesn’t become too soft during baking.
8. Toast the breadcrumbs (if using): For extra flavor and crispiness, toast the breadcrumbs in a dry skillet over medium heat until golden brown before sprinkling them on top of the casserole. Alternatively, toss them with melted butter and Parmesan cheese before topping the casserole.

FAQ Section

Q1: Can I make this casserole gluten-free?
A: Yes, you can easily make this casserole gluten-free! Simply substitute the all-purpose flour in the cheese sauce with a gluten-free all-purpose flour blend or cornstarch. Ensure your breadcrumbs, if using, are also gluten-free, or omit them for a naturally gluten-free topping. Always check the labels of your ingredients to confirm they are certified gluten-free if necessary.

Q2: Can I use frozen broccoli instead of fresh?
A: Yes, frozen broccoli florets can be used. There’s no need to thaw them completely. You can steam them directly from frozen, but you might need to steam them for a slightly longer time, around 8-10 minutes, until tender-crisp. Make sure to drain any excess water after steaming to prevent a watery casserole. Fresh broccoli, however, generally provides a better texture.

Q3: Can I use different types of cheese?
A: Absolutely! This recipe is very flexible when it comes to cheese. Feel free to experiment with your favorite cheeses. Gruyere, Swiss, provolone, pepper jack, or even a smoked gouda would be delicious alternatives or additions. Consider the melting properties and flavor profiles of different cheeses when making your selections to achieve your desired taste and texture.

Q4: Is this casserole vegetarian?
A: Yes, as written, this Cheesy Broccoli & Quinoa Casserole is vegetarian. It uses vegetable broth and no meat products. To ensure it remains vegetarian, always check the labels of your ingredients, especially if using pre-shredded cheese, as some may contain animal rennet.

Q5: Can I add meat to this casserole?
A: Yes, you can easily add cooked meat to this casserole to make it a non-vegetarian dish. Cooked and crumbled bacon, shredded cooked chicken, or ground beef would all be great additions. Add the cooked meat to the casserole when you combine the quinoa, broccoli, and cheese sauce.

Q6: How do I reheat leftover casserole?
A: Leftover Cheesy Broccoli & Quinoa Casserole reheats well. You can reheat it in the microwave in individual portions for a quick lunch or dinner. For larger portions or the whole casserole, reheat it in the oven at 350°F (175°C) for 15-20 minutes, or until heated through. Cover the casserole with foil to prevent the top from browning too much and to retain moisture.

Q7: Can I make this casserole dairy-free or vegan?
A: Making this casserole dairy-free or vegan requires substitutions for the dairy components. You can use plant-based butter, plant-based milk (like almond, soy, or oat milk), and vegan cream cheese alternatives. For the cheddar, Monterey Jack, and Parmesan cheese, use vegan shredded cheese alternatives. The taste and texture will be slightly different, but it can still be a delicious and satisfying vegan dish. Nutritional yeast can also be added for a cheesy flavor boost in vegan versions.

Q8: What if my cheese sauce is lumpy?
A: Lumpy cheese sauce can often be fixed! If your sauce is lumpy, you can try a couple of things. First, whisk it vigorously. Sometimes lumps will break down with enough whisking. If that doesn’t work, you can strain the sauce through a fine-mesh sieve to remove the lumps. For future batches, ensure you are gradually adding the milk to the roux and whisking constantly to prevent lumps from forming in the first place. Using warmed milk can also help in creating a smoother sauce.
