Ingredients
3–4 cups cooked chicken, shredded or diced
2 heads fresh broccoli, cut into florets (about 6 cups)
1/2 cup unsalted butter
1/2 cup all-purpose flour
2 cups whole milk
1/4 cup mayonnaise
1 tbsp Dijon mustard
1/2 tsp onion powder
1/2 tsp garlic powder
1 tsp salt
1/2 tsp black pepper
2 cups shredded sharp cheddar cheese
1 cup shredded Gruyère cheese (or Swiss)
1/2 cup panko breadcrumbs
2 tbsp melted butter (for topping)
Instructions
Step 1: Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
Step 2: Blanch broccoli florets in boiling salted water for 2-3 minutes until bright green and tender-crisp. Immediately drain and plunge into an ice bath; drain thoroughly and pat very dry. Arrange broccoli evenly in the baking dish.
Step 3: Distribute the cooked, shredded chicken evenly over the broccoli.
Step 4: In a large saucepan, melt 1/2 cup butter over medium heat. Sprinkle in the flour, whisking constantly for 1-2 minutes to create a smooth roux.
Step 5: Gradually whisk in the milk, a little at a time, until the sauce is smooth. Continue to cook, whisking occasionally, until the sauce thickens and begins to bubble, about 5-7 minutes.
Step 6: Remove from heat. Stir in the mayonnaise, Dijon mustard, onion powder, garlic powder, salt, and pepper until well combined.
Step 7: Add the shredded cheddar and Gruyère cheeses, stirring until melted and smooth. Taste and adjust seasonings as needed.
Step 8: Pour the cheese sauce evenly over the chicken and broccoli in the baking dish.
Step 9: In a small bowl, combine panko breadcrumbs and 2 tbsp melted butter. Sprinkle evenly over the top of the casserole.
Step 10: Bake for 25-30 minutes, or until bubbling around the edges and the topping is golden brown and crispy.
Step 11: Remove from oven and let rest for 5-10 minutes before serving. Enjoy your delicious chicken divan recipe!
Notes
For best results, use freshly grated cheese. This casserole can be assembled ahead of time (without the breadcrumbs) and refrigerated for up to 24 hours. Add breadcrumbs just before baking. Leftovers store well in an airtight container for 3-4 days.
