Ingredients for summer broccoli cheddar casserole crowd
- 2 lbs fresh broccoli florets
- 2 cups sharp cheddar cheese, shredded
- 1 cup panko breadcrumbs
- 4 tbsp butter
- 3 cloves garlic, minced
- 1 cup heavy cream
- 1 cup chicken broth
- 3 eggs
- 1 tsp salt
- 1/2 tsp black pepper
- 1/2 tsp garlic powder
- 1/4 tsp cayenne pepper
- 2 tbsp fresh parsley, chopped
- 1/2 cup parmesan cheese, grated
- 2 tbsp olive oil
Substitutions are simple with this broccoli cheddar bake—use cauliflower for half the vegetables, Swiss cheese instead of cheddar, or panko mixed with crushed crackers. For dairy-free versions, substitute heavy cream with coconut cream and use dairy-free cheddar alternative, though the crowd broccoli casserole will have slightly different flavor and texture results.
Fresh herbs like dill or tarragon elevate this summer casserole beautifully, while smoked paprika adds unexpected depth. Room temperature ingredients blend more smoothly into the creamy sauce, reducing lumps significantly. Don’t skip the parmesan topping—it creates the signature golden crust everyone loves.
Step-by-step crowd broccoli casserole instructions
1. Preheat your oven to 375°F and lightly grease a 9×13-inch baking dish with cooking spray or butter. Bring a large pot of salted water to a boil, then add fresh broccoli florets and cook for exactly 3 minutes until bright green but still crisp.
2. Drain broccoli thoroughly in a colander, then spread on a clean kitchen towel to remove excess moisture completely. This step prevents a watery casserole and ensures proper binding with the custard mixture throughout baking.
3. Melt butter in a large saucepan over medium heat, then add minced garlic and cook for 1 minute until fragrant. Whisk in heavy cream and chicken broth, stirring constantly for 2 minutes until the summer broccoli cheddar casserole crowd’s base sauce thickens slightly.
4. Remove from heat and stir in shredded cheddar cheese, salt, black pepper, garlic powder, and cayenne pepper until completely melted and smooth. Beat eggs in a small bowl, then temper by slowly whisking in one cup of hot sauce while constantly stirring.
5. Pour the egg mixture back into the saucepan, whisking gently to combine without scrambling the eggs throughout the creamy mixture. Transfer blanched broccoli to your prepared baking dish, then pour the cheese custard over florets, stirring gently to distribute evenly.
6. In a small bowl, combine panko breadcrumbs with grated parmesan cheese and melted olive oil, mixing with a fork until crumbly. Sprinkle this topping evenly over the casserole, then bake for 35-40 minutes until the top is golden brown and a knife inserted in the center comes out clean.
7. Let the broccoli cheddar bake rest for 5 minutes before serving, which allows the custard to set properly. Garnish with fresh chopped parsley and serve warm alongside grilled meats or fresh summer salads.

Yes, absolutely! Freeze assembled casseroles unbaked in freezer-safe dishes for up to three months maximum.Thaw overnight in the refrigerator, then bake as directed, adding 5-10 minutes to the total cooking time. For best results, freeze without the breadcrumb topping and add it fresh before baking.
What cheese works best in this easy summer casserole?
Sharp aged cheddar delivers the most flavorful results because it has concentrated, complex taste that survives oven baking beautifully.Gruyère, smoked cheddar, or a blend of sharp white and orange cheddar also work wonderfully. Avoid pre-shredded cheese with anti-caking agents, which creates a grainy texture in the cream sauce.

Preheat your oven to exactly **350°F**, cover the casserole with foil, and bake for **15-18 minutes** until heated through completely.Alternatively, reheat individual portions in the microwave on 50% power for 2-3 minutes to prevent overcooking the edges.
