Pin it

Introduction

This one-dish casserole combines seared chicken, broccoli, and a creamy celery soup base seasoned with curry powder—ready in under an hour with minimal prep. The dish bakes covered at 375°F for 30 minutes, which keeps the chicken moist while the flavors meld together, making it practical for a weeknight dinner or meal prep.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 35 minutes
• Total Time: 50 minutes
• Servings: 4

Ingredients

• 1 lb chicken breast, cubed
• 14 oz frozen broccoli
• 10.5 oz canned cream of celery soup
• 4 oz mayonnaise
• 6 oz skim milk
• 1 teaspoon curry powder

Instructions

1. Sear the cubed chicken in saucepan.
2. Place cooked chicken and remaining ingredients into a casserole dish.
3. Cover with foil and bake in oven at 375°F for 30 minutes.
4. Serve with rice.

Variations

Add sautéed onions and garlic: Sauté diced onion and minced garlic in the saucepan before searing the chicken. This builds a savory base layer and deepens the overall flavor.

Use fresh broccoli instead of frozen: Cut fresh broccoli into florets and increase the baking time by 5–10 minutes to ensure tenderness. Fresh broccoli releases more water, so you may reduce the milk by 1 tablespoon.

Swap curry powder for paprika and thyme: Use 1 teaspoon smoked paprika and ½ teaspoon dried thyme for a milder, earthier profile without the curry warmth.

Stir in shredded cheddar cheese: Add ¾ cup shredded cheddar cheese to the casserole mixture before baking for a richer, more indulgent dish. Reduce the milk to 4 oz to compensate for the cheese moisture.

Top with breadcrumbs before baking: Mix ½ cup panko breadcrumbs with 2 tablespoons melted butter and sprinkle on top before baking. Remove the foil for the final 10 minutes so the topping browns.

Tips for Success

Don’t skip searing the chicken: Browning the cubed chicken in the saucepan develops flavor through caramelization, which makes a real difference in the final dish’s depth.

Use a low-sided casserole dish: A 9×13-inch dish allows even heat circulation and prevents the mixture from bubbling over during the 30-minute bake.

Stir gently after removing foil: If you want a more even distribution of creamy sauce, lift the foil halfway through baking and give it a light stir, being careful not to break up the chicken.

Check that the chicken is fully cooked before assembling: The chicken should reach 165°F internally before going into the casserole. Since it bakes at 375°F, fully cooked chicken won’t overcook in the final 30 minutes.

Let it rest 5 minutes after baking: The casserole will be very hot and the sauce will continue to thicken slightly as it cools, making it easier to serve without it sliding across the plate.

Storage and Reheating

Refrigerator: Store covered in an airtight container for up to 3 days. The casserole holds well because the cream-based sauce protects the chicken from drying out.

Freezer: This casserole freezes well for up to 2 months. Cool it completely, cover tightly with foil and plastic wrap, and thaw overnight in the fridge before reheating.

Reheating: Preheat the oven to 350°F, cover the casserole with foil, and bake for 20–25 minutes until heated through. Alternatively, reheat individual portions in the microwave at 50% power for 3–4 minutes to avoid overcooking the chicken.

FAQ

Can I prepare this casserole the night before and bake it the next day?

Yes. Assemble the casserole completely, cover it tightly, and refrigerate overnight. Add 5–10 minutes to the bake time since it will go into the oven cold.

What kind of rice pairs best with this casserole?

Jasmine or basmati rice complements the mild curry notes. White or brown rice works equally well if you prefer a neutral backdrop.

Can I use chicken thighs instead of chicken breast?

Thighs will stay moister during baking and can handle the longer cook time without drying out, though they have more fat. Cube them to the same size and follow the recipe as written.

Is there a dairy-free version?

Substitute the mayonnaise with dairy-free mayo and the skim milk with unsweetened coconut milk or oat milk in equal amounts. The sauce will be thinner but still coat the chicken and broccoli adequately.
