What You’ll Need
- Cooked chicken: 3 cups, chopped or shredded (rotisserie chicken works great)
- Broccoli florets: About 5 cups, fresh or frozen
- Butter: 4 tablespoons (divided for sauce and topping)
- All-purpose flour: 3 tablespoons
- Chicken broth: 1 cup, low-sodium
- Milk or half-and-half: 1 cup (milk for lighter, half-and-half for richer)
- Mayonnaise: 1/3 cup (adds body and tang)
- Sour cream or Greek yogurt: 1/3 cup
- Dijon mustard: 1 teaspoon
- Lemon juice: 1–2 tablespoons, to taste
- Garlic powder: 1/2 teaspoon
- Onion powder: 1/2 teaspoon
- Salt and black pepper: To taste
- Sharp cheddar cheese: 1 1/2 cups, shredded
- Parmesan cheese: 1/4 cup, grated
- Panko breadcrumbs: 1 cup (or crushed Ritz crackers)
- Paprika: A pinch, optional for color
- Cooking spray or extra butter: For greasing the dish
How to Make It
- Heat the oven: Preheat to 375°F (190°C). Grease a 9×13-inch baking dish.
- Prep the broccoli: Blanch fresh florets in salted boiling water for 2–3 minutes until bright green and just tender.
Drain and pat dry. If using frozen, thaw and squeeze out excess moisture.
- Make the roux: In a saucepan, melt 3 tablespoons of butter over medium heat. Whisk in flour and cook 1 minute to remove raw taste.
- Build the sauce: Slowly whisk in chicken broth, then milk.
Simmer 2–3 minutes until slightly thickened. Remove from heat and stir in mayonnaise, sour cream, Dijon, lemon juice, garlic powder, onion powder, 1 cup cheddar, and Parmesan. Season with salt and pepper.
The sauce should be creamy and pourable; add a splash of broth if too thick.
- Layer the dish: Spread broccoli evenly in the baking dish. Scatter chicken on top. Pour the sauce over, nudging it into the corners so everything is coated.
- Add cheese: Sprinkle remaining 1/2 cup cheddar over the surface.
- Make the topping: Melt the remaining 1 tablespoon butter.
Toss with panko and a pinch of paprika. Sprinkle over the casserole for a crunchy finish.
- Bake: Bake uncovered for 22–28 minutes, until bubbly around the edges and the top is golden. If the topping needs more color, broil 1–2 minutes, watching closely.
- Rest and serve: Let sit 5–10 minutes to set.
Serve warm with a simple green salad, rice, or buttered noodles.
How to Store
- Refrigerate: Cool completely, then cover and refrigerate for up to 4 days.
- Reheat: Warm individual portions in the microwave or reheat the whole dish at 325°F until hot. If the topping softens, refresh under the broiler for 1 minute.
- Freeze: Assemble without the crumb topping, wrap tightly, and freeze up to 2 months. Thaw in the fridge overnight, add topping, and bake as directed.
- Make-ahead: Assemble up to 24 hours in advance.
Cover and refrigerate. Add 5–10 minutes to the bake time.
Benefits of This Recipe
- Great use of leftovers: Rotisserie chicken or leftover roast chicken turns into a new meal.
- Balanced plate: Includes protein, veggies, and dairy in one pan.
- Kid-approved: Creamy sauce and cheese help picky eaters enjoy their broccoli.
- Customizable: Easy to adapt for gluten-free or lighter versions without losing comfort.
- Feeds a crowd: Scales up easily and travels well for potlucks.
Pitfalls to Watch Out For
- Watery casserole: Overcooked or wet broccoli can dilute the sauce. Blanch briefly and dry well, or squeeze thawed frozen broccoli.
- Curdled sauce: Don’t boil after adding dairy.
Remove from heat before stirring in mayo, sour cream, and cheeses.
- Bland flavor: Season the sauce generously and don’t skip the lemon. Taste and adjust salt, pepper, and acidity.
- Soggy topping: Add crumbs just before baking and leave the casserole uncovered.
- Overbaking: Bake until just bubbly. Extra time can dry out the chicken and dull the broccoli.
Alternatives
- Protein swaps: Turkey, ham, or shredded rotisserie turkey work well.
For vegetarian, try chickpeas or white beans.
- Veggie variations: Mix in cauliflower, peas, or sautéed mushrooms. Keep total veggie volume similar to avoid excess moisture.
- Cheese options: Gruyère or Swiss add classic Divan flair; Monterey Jack melts beautifully; a little blue cheese for boldness.
- Gluten-free: Use 1:1 gluten-free flour for the roux and gluten-free panko.
- Lighter version: Use 2% milk, Greek yogurt instead of sour cream, and reduce cheese by 1/2 cup. It will still be creamy.
- No mayo: Replace with more sour cream or Greek yogurt plus a teaspoon of olive oil for richness.
- Cracker topping: Use crushed buttery crackers instead of panko for extra savoriness.
FAQ
Can I use canned soup instead of making the sauce?
Yes.
Use one can of cream of chicken or cream of broccoli soup plus 1/2 to 2/3 cup milk, then add Dijon, lemon juice, and seasonings to taste. The homemade sauce has fresher flavor, but the shortcut works.
Do I have to cook the broccoli first?
Blanching gives the best texture and keeps the color vibrant. If you skip it, use smaller florets and add 5–10 minutes to the bake time, but watch for extra moisture.
What’s the best chicken to use?
Rotisserie chicken is convenient and flavorful.
Poached or roasted chicken breasts or thighs also work. Aim for bite-size pieces so every forkful has a mix of chicken and broccoli.
How do I keep the topping crunchy when reheating?
Reheat gently and finish with a quick broil to crisp the crumbs. You can also add a small handful of fresh panko tossed with melted butter over the top before broiling.
Can I make it in advance for a party?
Absolutely.
Assemble the casserole without the topping up to 24 hours ahead. Add the topping right before baking so it stays crisp and golden.
Is Chicken Divan traditionally made with curry powder?
Some older versions include a pinch of curry powder. If you like that warm note, add 1/2 teaspoon to the sauce.
It plays nicely with the cheddar and broccoli.
