Protein
- 2 cups cooked chicken breast, shredded or diced
Vegetables
- 3 cups fresh broccoli florets
Dressing & Sauce
- 1/2 cup mayonnaise
- 1/2 cup sour cream
- 1 tablespoon Dijon mustard
- 1 tablespoon fresh lemon juice
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Topping
- 1 1/2 cups shredded sharp cheddar cheese
- 1/2 cup breadcrumbs (use gluten-free if needed)
- Prepare Your Ingredients: Preheat the oven to 375°F (190°C). Steam or blanch the broccoli florets until just tender but still crisp. Shred or dice the cooked chicken breast to ensure tender, even pieces.
- Mix the Creamy Sauce: In a medium bowl, combine mayonnaise, sour cream, Dijon mustard, lemon juice, garlic powder, onion powder, salt, and pepper. Stir until the sauce is smooth and creamy.
- Combine Broccoli, Chicken, and Sauce: In a large mixing bowl, gently fold the cooked chicken and broccoli into the sauce mixture. Make sure everything is well coated without breaking the broccoli florets.
- Assemble the Casserole: Transfer the mixture to a greased baking dish, spreading it out evenly. Sprinkle shredded cheddar cheese evenly on top, then add breadcrumbs to create a golden, crispy crust.
- Bake Until Bubbling and Golden: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is melted, bubbly, and the breadcrumbs turn a golden brown.
Notes
- Use fresh broccoli to retain bright color and texture.
- Steam broccoli until just tender to avoid mushy florets post-baking.
- Opt for sharp cheddar or a cheese blend for richer flavor.
- Homemade cooked chicken (roasted or poached) offers more flavor than store-bought.
- Let casserole rest 5-10 minutes after baking to set for easier serving.
