Broccoli Casserole Ingredients
For the Casserole

• Butter – brings rich flavor; substitute with olive oil for a lighter option.
• Cremini mushrooms – adds umami depth; omit if preferred or swap for sautéed garlic.
• Yellow onion – imparts sweetness to the cream sauce; shallots offer a milder flavor.
• Flour – thickens the cream sauce; use gluten-free flour for a gluten-free version.
• Milk (whole/2%) – gives creaminess to the sauce; plant-based milk serves as a dairy-free option.
• Half and half – enhances the creaminess; mix cream with milk for a substitute.
• Salt & pepper – essential for seasoning; adjust based on your taste preferences.
• Plain Greek yogurt – adds tangy creaminess; sour cream or mayonnaise works too.
• Egg – binds everything together; a flax egg is perfect for a vegan choice.
• Grated cheddar cheese – provides rich flavor; any melty cheese like Monterey Jack works well.
• Whole-wheat breadcrumbs – adds a crunchy topping; consider panko for extra crispiness.
For the Topping
• Remaining breadcrumbs – enhances texture; crushed Ritz crackers add a buttery touch.
• Additional grated cheese – boosts cheesiness in the topping; try different varieties like Gruyère.
This Broccoli Casserole not only satisfies the taste buds but also embodies the warmth of homemade cooking.
Step‑by‑Step Instructions for Broccoli Casserole
Step 1: Preheat and Prepare the Baking Dish
Begin by preheating your oven to 350°F (175°C). While the oven warms, lightly spray a 3-quart or 9×13-inch baking dish with cooking spray to prevent sticking. This step ensures your cheesy broccoli casserole comes out easily, allowing every delicious bite to be savored without any fuss.
Step 2: Blanch the Broccoli
In a large pot, bring water to a boil and carefully add the broccoli florets. Blanch them for about 4 minutes until they are just crisp-tender; you want to maintain a vibrant green color! Drain the broccoli and immediately transfer it to a bowl of ice water to stop the cooking process, then set it aside to cool.
Step 3: Sauté the Aromatics
In a spacious skillet, melt 3 tablespoons of butter over medium heat. Once melted, add the finely chopped yellow onion and sliced cremini mushrooms, cooking for about 5-7 minutes until they become tender and fragrant. This sautéing step enhances the overall flavor profile of your homemade broccoli casserole.
Step 4: Create the Cream Sauce
In the same skillet, sprinkle 1/4 cup of flour over the melted butter and stir for about a minute to form a roux. Gradually whisk in 2 cups of milk and 1/2 cup of half and half, cooking until the mixture thickens and bubbles, about 4-5 minutes. Now, stir in seasonings to taste, followed by 1/2 cup of plain Greek yogurt for a creamy texture.
Step 5: Combine Ingredients
In a large mixing bowl, combine the sautéed mushrooms and onions with the blanched broccoli. Pour in the cream sauce, followed by one beaten egg, 1 cup of grated cheddar cheese, and 1/2 cup of whole-wheat breadcrumbs. Gently mix until all ingredients are coated well, ensuring a creamy consistency throughout your broccoli casserole.
Step 6: Transfer to Baking Dish
Now that your mixture is well combined, transfer it into the prepared baking dish. Spread it evenly across the bottom of the dish so that every bite is full of flavor. This step establishes a solid foundation for the crispy topping that will crown your broccoli casserole.
Step 7: Prepare the Topping
In a small bowl, melt 2 tablespoons of butter and mix it with the remaining 1/2 cup of breadcrumbs and 1/2 cup of grated cheese until everything is evenly coated. This delightful crumb mix will create a deliciously crunchy topping for your casserole, adding texture and flavor that perfectly complements the creamy filling.
Step 8: Bake to Perfection
Cover the baking dish with foil and bake in the preheated oven for 30 minutes. After that, remove the foil and continue to bake for an additional 15 to 20 minutes, or until the top is golden brown and bubbly. This final baking step allows the flavors to meld and ensures a warm, inviting presentation for your broccoli casserole.
Step 9: Rest and Serve
Once baked, remove the casserole from the oven and let it rest for about 10 minutes. This resting period allows the casserole to set, making it easier to serve and enjoy. Now, it’s time to gather your loved ones and share this comforting homemade broccoli casserole at your next family gathering!

Make Ahead Options
These Homemade Creamy Broccoli Casseroles are perfect for busy weeknights or holiday meal prep! You can assemble the entire casserole up to 24 hours in advance by preparing it through the topping step. Just cover it tightly with foil and refrigerate to maintain freshness. When you’re ready to bake, take it out and let it sit at room temperature for about 30 minutes before popping it in the oven; this helps ensure even cooking. For up to 3 days of prep ahead, you can also prepare the cream sauce separately, refrigerate it, and mix it with the other components just before baking. With these make-ahead tips, your Broccoli Casserole will be just as delicious and save you precious time!
