Why I Love This Recipe

This is the kind of casserole I like when I want comfort food but do not want a long night in the kitchen. Chicken and broccoli are simple on their own, but cottage cheese changes the whole dish. Once blended with milk and seasonings, it becomes a smooth sauce that coats everything.

The first spoonful has a little bit of everything: juicy chicken, tender broccoli, creamy sauce, melted cheddar, and crunchy breadcrumbs. I also love that there is no canned cream soup in the recipe.

• It uses simple grocery-store ingredients.
• Cottage cheese makes the sauce creamy and adds extra protein.
• Broccoli adds color and a fresh bite.
• Cheddar gives it plenty of cheesy flavor.
• Panko makes the top crisp instead of soft.
• Leftovers reheat well for an easy lunch.

What You’ll Need

• 1 1/2 pounds boneless, skinless chicken breasts, cut into 1-inch pieces
• 1 tablespoon olive oil
• 1/2 teaspoon salt, divided
• 1/4 teaspoon black pepper
• 4 cups fresh broccoli florets, cut into bite-size pieces
• 2 cups cottage cheese
• 1/2 cup milk
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1/2 teaspoon dried Italian seasoning
• 2 cups shredded sharp cheddar cheese, divided
• 1/2 cup panko breadcrumbs
• 1 tablespoon melted butter
• 2 tablespoons chopped fresh parsley, optional

Recipe and Instructions

Step 1: Prep the Oven and Chicken

Heat the oven to 375°F (190°C). Lightly grease a 9-by-13-inch baking dish.

Cut 1 1/2 pounds boneless, skinless chicken breasts into 1-inch pieces. Season the chicken evenly with 1/4 teaspoon salt and 1/4 teaspoon black pepper.

Step 2: Cook the Chicken

Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add all of the seasoned chicken from Step 1.

Cook for about 5 to 7 minutes, stirring a few times, until the outside is lightly golden and the chicken reaches 165°F (74°C) in the thickest pieces. Transfer the cooked chicken to a plate.

Step 3: Blanch the Broccoli

Bring a pot of water to a boil. Add 4 cups bite-size fresh broccoli florets and cook for 2 minutes.

Drain very well. Let the broccoli sit for a minute so extra steam can escape. This keeps excess water out of the casserole.

Step 4: Make the Cottage Cheese Sauce

Add 2 cups cottage cheese, 1/2 cup milk, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1/2 teaspoon dried Italian seasoning, and the remaining 1/4 teaspoon salt to a blender.

Blend until smooth and creamy, about 30 to 45 seconds.

Step 5: Mix the Filling

Put the cooked chicken from Step 2 and drained 4 cups broccoli florets from Step 3 into a large mixing bowl.

Pour in all of the blended cottage cheese sauce from Step 4. Add 1 cup shredded sharp cheddar cheese. Gently stir until the chicken and broccoli are evenly coated.

Spread the mixture evenly in the prepared 9-by-13-inch baking dish.

Step 6: Add the Cheesy Crunchy Topping

Sprinkle the remaining 1 cup shredded sharp cheddar cheese evenly over the casserole.

In a small bowl, mix 1/2 cup panko breadcrumbs with 1 tablespoon melted butter. Sprinkle the buttered panko evenly over the cheddar.

Step 7: Bake

Place the casserole in the 375°F (190°C) oven.

Bake uncovered for 20 to 25 minutes, until the sauce is bubbling around the edges and the cheddar is melted. The panko should look golden and crisp.

Step 8: Rest and Serve

Let the casserole rest for 5 to 10 minutes. This gives the creamy sauce time to settle.

Sprinkle with 2 tablespoons chopped fresh parsley, if using. Spoon the casserole into a round serving bowl and serve warm.

Why This Recipe Works (Quick Science)

Cottage cheese has protein and moisture. Blending it with milk breaks up the curds and turns it into a much smoother sauce.

Cooking the chicken first gives you better control over doneness. Blanching the broccoli for only 2 minutes starts the cooking process without making it mushy.

Draining the broccoli matters, too. Water trapped in broccoli can leak into the casserole and thin the sauce.

Finally, cheddar melts over the filling while butter helps the panko turn crisp and golden. That gives you creamy filling underneath and crunch on top.

Pro Tips

• Drain the broccoli well. Wet broccoli is one of the easiest ways to end up with a watery casserole.
• Cut the chicken evenly. Similar-size pieces cook at about the same speed.
• Blend the cottage cheese. This gives the casserole a much smoother, creamier texture.
• Use freshly shredded cheddar when possible. It usually melts more smoothly than bagged pre-shredded cheese.
• Give it time to rest. Five to 10 minutes helps the hot sauce thicken before serving.

Tools You’ll Need

• 9-by-13-inch baking dish
• Large skillet
• Medium pot
• Blender
• Large mixing bowl
• Small mixing bowl
• Cutting board
• Chef’s knife
• Colander
• Wooden spoon
• Silicone spatula
• Measuring cups
• Measuring spoons
• Instant-read meat thermometer

Substitutions and Variations

• Chicken thighs: Use boneless, skinless chicken thighs instead of chicken breasts.
• Frozen broccoli: Thaw it completely and squeeze or drain away as much moisture as possible. Skip blanching.
• Cheese: Monterey Jack, Colby Jack, or a cheddar blend can replace sharp cheddar.
• Breadcrumbs: Regular breadcrumbs can replace panko, although the topping will be less crunchy.
• Gluten-free: Use gluten-free panko.
• More vegetables: Try adding cooked mushrooms or diced red bell pepper. Cook watery vegetables before adding them.
• A little heat: Add 1/4 teaspoon crushed red pepper flakes to the cottage cheese sauce.

Make-Ahead Tips

You can cook the chicken, blanch the broccoli, and blend the sauce up to 1 day ahead. Store each part covered in the refrigerator.

You can also assemble the casserole without the panko topping and refrigerate it for up to 24 hours. Add the buttered panko just before baking. A cold casserole may need an extra 5 to 10 minutes in the oven.

Common Mistakes

• Using wet broccoli: This can make the casserole watery.
• Overcooking the broccoli: Blanch it for only 2 minutes because it cooks again in the oven.
• Using large chicken pieces: Smaller, even pieces are easier to cook evenly and eat.
• Skipping the blender: Unblended cottage cheese will give you a much lumpier sauce.
• Skipping the resting time: The casserole is very hot and loose right out of the oven. A short rest improves the texture.
• Burning the topping: If the panko browns too quickly, loosely cover the casserole with foil for the remaining baking time.

What to Serve With

This casserole already has chicken and broccoli, so simple sides work best.

• A crisp green salad
• Garlic bread
• Warm dinner rolls
• Roasted carrots

• Quinoa
• Fresh sliced tomatoes

Macros Information

Approximate nutrition for 1 of 6 servings:

These numbers are estimates. The exact macros will change with the brands of cottage cheese, milk, cheddar, breadcrumbs, and chicken you use.

Leftovers and Storage

Let leftovers cool, then place them in an airtight container. Refrigerate for up to 3 to 4 days.

Reheat individual servings in the microwave until steaming hot. For a crispier topping, reheat the casserole in a 350°F (175°C) oven until hot throughout.

You can freeze individual portions for up to 2 months. Keep in mind that cottage cheese sauce and broccoli can release some water after freezing and thawing. Thaw overnight in the refrigerator before reheating.

FAQ

Q: Will the casserole taste strongly like cottage cheese?

A: Not much. Blending the cottage cheese with milk and seasonings gives it a smooth texture, while cheddar provides most of the cheesy flavor.

Q: Can I use frozen broccoli?

A: Yes. Thaw it first and drain it very well. You do not need to blanch frozen broccoli.

Q: Do I have to blend the cottage cheese?

A: No, but blending is recommended. It creates the smooth, creamy sauce this recipe is designed to have.

Q: Why did my casserole turn watery?

A: The most common cause is extra water from the broccoli. Drain blanched broccoli very well, and make sure thawed frozen broccoli is not holding extra moisture.

Q: Can I use leftover cooked chicken?

A: Yes. Use about 4 cups chopped cooked chicken. Skip the chicken-cooking step and mix the cooked chicken directly with the broccoli, sauce, and cheese.

Q: How do I know when the casserole is ready?

A: The edges should be bubbling, the cheese should be fully melted, and the panko should be golden. Because the chicken is already cooked before assembly, you are mainly heating the casserole through and browning the topping.
