Broccoli Casserole Ingredients

For the Casserole
• Broccoli – Fresh, cut into bite-size pieces; essential for bulk and nutrition—frozen broccoli works if you’re pressed for time.
• Butter – Adds richness to both the sauce and topping; olive oil can be used for a lighter option.
• Cremini Mushrooms – Finely chopped to elevate the flavor; can be omitted or swapped with diced bell peppers for a different profile.
• Yellow Onion – Finely chopped, enhancing overall flavor; shallots are a milder alternative.
• Flour – All-purpose flour thickens the creamy sauce; gluten-free flour is a great substitute if needed.
• Milk – Whole or 2% is best for creaminess; almond or coconut milk offers a non-dairy option.
• Half and Half – Adds extra creaminess; mix milk and cream for a lighter version if desired.
• Salt and Black Pepper – For seasoning; adjust to suit your taste.
• Plain Greek Yogurt – Provides tanginess and creaminess; feel free to substitute with sour cream or mayonnaise.
• Egg – Acts as a binder, ensuring the casserole holds together; flaxseed meal or a commercial egg substitute works for a vegan option.
• Cheddar Cheese – Grated, offering flavor and creaminess; feel free to use Colby Jack or Monterey Jack instead.
• Whole-Wheat Breadcrumbs – Adds crunch to the topping; crushed Ritz crackers can be a tasty alternative.

For the Top Layer
• Butter – Melted, mixed with breadcrumbs to enhance flavor and texture.
• Extra Cheddar Cheese – Sprinkle some on top for an even cheesier topping that will delight broccoli casserole lovers!

Step‑by‑Step Instructions for Creamy Broccoli Casserole with a Crunchy Cheese Topping

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats, prepare a 9×13-inch baking dish by lightly coating it with cooking spray to prevent sticking. This step is important to ensure that your delicious broccoli casserole bakes evenly and releases easily when done.

Step 2: Prepare the Broccoli
In a large pot, bring salted water to a rolling boil. Add the fresh, bite-sized pieces of broccoli and cook for about 4 minutes until they are bright green and slightly crisp-tender. Drain the broccoli in a colander, then rinse under cold water to halt the cooking process and preserve that vibrant color. Set aside.

Step 3: Sauté the Vegetables
In a large skillet over medium heat, melt 2 tablespoons of butter. Once melted, add the finely chopped cremini mushrooms and yellow onion. Sauté these in the melted butter for about 4 minutes or until they’re softened and fragrant. This brings out the natural sweetness of the vegetables and lays the foundation for your casserole’s flavor.

Step 4: Create the Cream Sauce
Using the same skillet, sprinkle in the flour while whisking constantly for about a minute to form a roux with the remaining butter. Gradually add in 2 cups of milk and ½ cup of half-and-half, whisking until the mixture thickens and bubbles gently. Stir in salt, pepper, and Greek yogurt to create a velvety cream sauce that beautifully binds the ingredients of your broccoli casserole.

Step 5: Mix the Casserole
In a large mixing bowl, combine the cooked broccoli, sautéed mushrooms and onions, cream sauce, one beaten egg, half of the grated cheddar cheese, and a portion of the breadcrumbs. Gently fold everything together until the broccoli is well-coated in the creamy goodness. This mixture should be hearty and fragrant as it comes together.

Step 6: Transfer to Baking Dish
Carefully pour the broccoli mixture into the prepared baking dish, spreading it out evenly. Then, take the remaining breadcrumbs, mix them with 2 tablespoons of melted butter and the extra cheddar cheese, and sprinkle this golden topping generously over the casserole. This will ensure a satisfying crunch once baked.

Step 7: Bake the Casserole
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake the creamy broccoli casserole for 30 minutes to allow the flavors to meld. After 30 minutes, remove the foil and continue baking for another 15-20 minutes, or until the top is golden brown and crispy. This final golden layer adds texture and mouthwatering appeal to your dish.
