Ingredients
The magic of this casserole lives in its simple, high‑quality ingredients. Tender chicken breasts provide a lean protein foundation, while fresh broccoli adds a burst of color and a satisfying crunch. The sauce is built on a roux of butter and flour, enriched with whole‑milk cheddar for depth, and brightened with a splash of Dijon mustard. Finishing with a light breadcrumb topping gives a golden, textural contrast that makes every bite memorable.
Main Ingredients
- 4 boneless, skinless chicken breasts (about 1½ lb)
- 2 cups fresh broccoli florets
- 1 cup shredded sharp cheddar cheese
Cheddar Sauce
- 2 tablespoons unsalted butter
- 2 tablespoons all‑purpose flour
- 1 cup whole‑milk (or 2% milk)
- 1 teaspoon Dijon mustard
- ¼ teaspoon smoked paprika
Seasonings & Topping
- Salt and freshly ground black pepper, to taste
- ½ cup panko breadcrumbs
- 1 tablespoon melted butter (for topping)
Together these ingredients create a harmonious blend of savory, creamy, and slightly smoky notes. The butter‑flour roux thickens the sauce without lumps, while the cheddar supplies a sharp, melty richness. Broccoli’s natural sweetness offsets the cheese’s tang, and the breadcrumb topping adds a satisfying crunch that elevates the casserole from everyday to unforgettable.
Step-by-Step Instructions
Preparing the Chicken & Broccoli
Pat the chicken breasts dry, then season both sides with salt, pepper, and smoked paprika. While the chicken rests for about 10 minutes at room temperature, bring a pot of salted water to a boil and blanch the broccoli florets for 2 minutes, then shock them in ice water to retain color. This short blanch preserves texture and ensures the broccoli finishes cooking evenly in the oven.
Searing the Chicken
- Heat the skillet. Place a large oven‑safe skillet over medium‑high heat and add 1 tablespoon olive oil. When the oil shimmers, it’s hot enough for a quick sear that locks in juices.
- Sear each side. Lay the chicken breasts in the pan, leaving space between them. Cook 4‑5 minutes without moving them, then flip and sear the other side another 4‑5 minutes. You’re looking for a golden‑brown crust, not full doneness.
- Set aside. Transfer the seared chicken to a plate. The residual heat will continue cooking the meat while you build the sauce.
Making the Cheddar Sauce
- Create the roux. Reduce the heat to medium and add 2 tablespoons unsalted butter to the same skillet. Once melted, whisk in 2 tablespoons all‑purpose flour. Cook, stirring constantly, for 1‑2 minutes until the mixture turns a light nutty color—this eliminates raw flour taste.
- Incorporate the milk. Gradually pour 1 cup whole‑milk while whisking. Continue whisking until the sauce thickens, about 3‑4 minutes. It should coat the back of a spoon without looking watery.
- Flavor the sauce. Stir in 1 teaspoon Dijon mustard, ¼ teaspoon smoked paprika, and the shredded 1 cup sharp cheddar cheese. Keep stirring until the cheese melts completely and the sauce is smooth.
Assembling & Baking
- Combine ingredients. Nestle the seared chicken breasts back into the skillet, arranging them in a single layer. Evenly scatter the blanched broccoli around the chicken, then pour the cheddar sauce over everything, ensuring each piece is well‑coated.
- Add the topping. In a small bowl, mix ½ cup panko breadcrumbs with 1 tablespoon melted butter. Sprinkle the mixture over the casserole for a crisp, golden finish.
- Bake. Transfer the skillet to a preheated oven at 375°F (190°C). Bake for 20‑25 minutes, or until the sauce bubbles vigorously and the breadcrumb topping turns deep golden brown. An internal temperature of 165°F (74°C) confirms the chicken is fully cooked.
- Rest before serving. Allow the casserole to rest for 5 minutes after removing it from the oven. Resting lets the sauce thicken slightly and the juices redistribute, guaranteeing moist chicken and a cohesive dish.
Tips & Tricks
Perfecting the Recipe
Room‑temperature chicken. Let the breasts sit out for 10‑15 minutes before searing; this promotes even cooking and prevents a cold center.
Don’t overcrowd the pan. Sear in batches if necessary. Overcrowding creates steam, which stops the crust from forming.
Use a whisk for the roux. Constant whisking prevents lumps and ensures a silky sauce texture.
Watch the breadcrumb color. If the topping browns too quickly, loosely tent the casserole with foil for the remainder of baking.
Flavor Enhancements
Stir in a splash of dry white wine or a teaspoon of Worcestershire sauce when you add the milk for an extra layer of umami. A pinch of cayenne or red‑pepper flakes adds subtle heat that balances the cheese’s richness.
Common Mistakes to Avoid
Skipping the resting period leads to dry chicken because the juices spill out onto the plate. Also, avoid turning the heat up too high when making the roux; burnt butter ruins the sauce’s flavor.
Pro Tips
Freshly grated cheese. Grating cheddar moments before use yields a smoother melt compared to pre‑shredded varieties.
Invest in a digital thermometer. It guarantees the chicken reaches 165°F without overcooking.
Finish with herbs. Sprinkle chopped chives or parsley just before serving for a fresh, bright contrast.
Use an oven‑safe skillet. It lets you go from stovetop sear to oven bake without transferring, preserving flavor and saving cleanup time.
Variations
Ingredient Swaps
Swap the chicken for turkey cutlets or a firm plant‑based protein such as cubed tempeh for a vegetarian twist. Replace broccoli with cauliflower, green beans, or a mix of bell peppers to change the color palette. For a different cheese profile, try Gruyère or smoked mozzarella for added depth.
Dietary Adjustments
Use gluten‑free flour and panko to keep the dish safe for gluten‑intolerant guests. For dairy‑free needs, substitute butter with olive oil, milk with unsweetened almond milk, and cheddar with a sharp dairy‑free cheese alternative. Keto diners can replace the flour with almond flour and skip the breadcrumbs, opting for crushed pork rinds instead.
Serving Suggestions
Pair the casserole with a light citrus‑y fruit salad, toasted sourdough, or a simple quinoa pilaf. A dollop of Greek yogurt or a drizzle of hot sauce adds a tangy contrast for those who like a bit of zing at breakfast.
Storage Info
Leftover Storage
Allow the casserole to cool to room temperature, then transfer it to an airtight container. It will keep in the refrigerator for 3‑4 days. For longer keeping, portion into freezer‑safe bags or containers, seal tightly, and freeze for up to 3 months. Label with the date for easy reference.
Reheating Instructions
Reheat leftovers in a 350°F (175°C) oven, covered with foil, for 15‑20 minutes until the interior is hot and the topping regains its crunch. If you’re short on time, microwave individual portions on medium power for 2‑3 minutes, stirring halfway, and add a splash of milk to revive the sauce.
