Essential Ingredients You’ll Need

To create this magnificent breakfast casserole, you’ll need a selection of fresh and flavorful ingredients. Each component plays a crucial role in delivering a balanced, nutritious, and incredibly tasty dish. Full measurements are available in the recipe card below.

• Eggs: The foundational ingredient, eggs provide essential protein and act as the binder that holds this casserole together. For the best quality and flavor, consider using cage-free organic eggs, though any favorite large eggs will work perfectly. They contribute to the fluffy, satisfying texture of the dish.
• Milk: A splash of milk adds moisture and creaminess, making the casserole rich and tender. You can use any milk of your choice, whether it’s 2% milk as preferred by many, or a non-dairy alternative like almond or oat milk for a lactose-free version.
• Seasoning: A thoughtfully chosen blend of spices elevates the flavor profile. We use onion powder and garlic powder for a savory base, and Italian seasoning for an aromatic, herbaceous touch that complements the vegetables beautifully. These spices are pantry staples that bring warmth and depth.
• Fresh Herbs: Fresh parsley is added for a burst of vibrant color and a fresh, clean taste. Its subtle peppery notes brighten the entire dish. Feel free to experiment with other fresh herbs like chives or dill for different flavor dimensions.
• Cooked Quinoa: This ancient grain is a powerhouse of complete protein and fiber, making the casserole even more filling and nutritious. Ensure your quinoa is cooked and cooled before adding it to prevent it from absorbing too much liquid and altering the casserole’s texture.
• Bell Peppers: A large red bell pepper adds a touch of sweetness, a beautiful pop of color, and valuable vitamins. While red is fantastic, feel free to use any color bell pepper you prefer, such as yellow or orange, to customize the flavor and aesthetic.
• Broccoli or Broccolini: These green powerhouses are central to the casserole’s nutritional value and provide a pleasant earthy flavor and tender-crisp texture. Broccolini, with its slender stalks and smaller florets, offers a slightly milder taste, but finely chopped regular broccoli is an excellent and readily available substitute.
• Cheddar Cheese: The irresistible melty, savory element that brings everything together. Shredded cheddar cheese provides that classic comfort food taste. For a lighter option, you can opt for light or fat-free cheddar, or explore other cheeses like Monterey Jack, mozzarella, or a blend of Italian cheeses.

How To Make Broccoli Cheese Quinoa Casserole

Creating this delicious and healthy breakfast casserole is incredibly straightforward, involving just a few simple steps. Follow these instructions for a perfectly baked, golden-brown casserole:

1. Prepare Your Baking Dish: Begin by preheating your oven to 350°F (175°C). While the oven heats, lightly spray a 9×13-inch baking dish (or a similar size) with cooking oil spray. This crucial step prevents the casserole from sticking and ensures easy serving.
2. Whisk the Egg Mixture: In a large mixing bowl, crack the eggs and add the milk, onion powder, garlic powder, Italian seasoning, and chopped fresh parsley. Whisk vigorously until the eggs are thoroughly beaten and all the seasonings are well incorporated. This creates a uniform base for your casserole.



3. Combine the Solids: Gently stir in the cooked quinoa, diced bell pepper, finely chopped broccolini (or broccoli), and shredded cheddar cheese into the egg mixture. Fold these ingredients together until they are evenly distributed, ensuring every bite of your casserole will be packed with flavor and texture.



4. Transfer to Baking Dish: Carefully spoon the entire mixture into your prepared baking dish. Spread it out evenly, taking care not to push the ingredients too high around the edges if you prefer a neater appearance. The goal is an even thickness for consistent cooking.
5. Bake to Perfection: Cover the baking dish tightly with aluminum foil. Place it in the preheated oven and bake for approximately 45 minutes. The casserole is ready when the eggs are fully set in the center and the broccolini is tender. You can gently lift the foil to check for doneness. If you desire a golden-brown top, you can remove the foil for the last 5-10 minutes of baking.
6. Rest and Serve: Once baked, remove the casserole from the oven and let it rest for 5-10 minutes before slicing and serving. This allows the casserole to set further, making it easier to cut into neat portions.

What To Serve It With

This versatile Broccoli Cheese Quinoa Breakfast Casserole pairs wonderfully with a variety of sides, enhancing your meal and adding extra layers of flavor and nutrition. Here are some delightful suggestions:

• Easy Marinated Tomatoes: The bright acidity and fresh taste of marinated tomatoes offer a perfect counterpoint to the rich and savory casserole.
• Air Fryer Zucchini Chips: For a lighter, crispy crunch, these healthy zucchini chips provide a fantastic textural contrast without added guilt.
• Creamed Peas: A classic comfort food side, creamed peas add a touch of sweetness and a creamy texture that complements the casserole beautifully.
• Avocado Cucumber Tomato Salad: A refreshing and vibrant salad brings coolness and a burst of fresh flavors, making your breakfast feel more like a complete brunch spread.
• Baked Garlic Butter Hasselback Potatoes: For a heartier meal, these flavorful and visually impressive potatoes are a delightful addition, offering a comforting starch component.
• Fresh Fruit Salad: A simple bowl of mixed berries, sliced melon, or citrus segments can add a refreshing, sweet element to balance the savory casserole.
• Whole-Grain Toast or English Muffins: Serve with a side of whole-grain toast for extra crunch and to soak up any delicious juices.

Tips for Success & Exciting Variations

Achieve casserole perfection and unleash your culinary creativity with these helpful tips and delicious variations:

• Preparation Pointers:
  • Inspect and Rinse Broccolini: Before chopping, thoroughly inspect and rinse your broccolini (or broccoli) to remove any dirt or impurities. Pat it completely dry to avoid excess moisture in your casserole, which can lead to a watery texture.
  • Rinse Quinoa Properly: For quinoa, rinsing is key! Before cooking, rinse it well under cold water to remove saponins – natural compounds that can impart a bitter, soapy taste. This simple step ensures your quinoa is delightfully mild and fluffy.
  • Consider Toasting Quinoa: If you’re new to cooking quinoa or simply want to enhance its flavor, try toasting it lightly in a dry pan for a few minutes before adding water to cook. This process brings out a nutty, deeper flavor that adds a whole new dimension to the grain and your casserole.
• Creative Add-ins and Toppings for Your Casserole: This recipe is incredibly adaptable, allowing you to customize it with your favorite ingredients.
  • Add Protein: Boost the protein content and heartiness by incorporating diced cooked chicken, breakfast sausage (pork or plant-based), or leftover shredded turkey. Sauté these additions briefly before mixing them in.
  • Experiment with Cheese: Beyond cheddar, crumble in some tangy feta cheese or creamy herbed goat cheese for different flavor profiles. A blend of mozzarella and Parmesan can also create a rich, melty experience.
  • Extra Veggies: Increase the vegetable goodness with shredded carrots for sweetness, sautéed mushrooms for an earthy depth, or blanched and quartered Brussels sprouts for a unique texture and flavor. Diced tomatoes and red onion can be added during mixing or sprinkled on top after baking for freshness.
  • Spice It Up: For a kick, add a pinch of red pepper flakes to the egg mixture, or top individual servings with pickled jalapeños. A dash of hot sauce is also a fantastic way to add heat.
  • Creamy Toppings: A dollop of sour cream or Greek yogurt on top of your warm casserole can add a cool, tangy contrast that’s incredibly delicious.
  • Herby Finish: Garnish with extra fresh herbs like chives, dill, or basil just before serving for an aromatic finish.
