Recipe Overview
- Prep Time: 10 minutes
- Cook Time: 45 minutes
- Total Time: 55 minutes
- Yield: 6 servings
Ingredients
- 1 tablespoon olive oil (for prepping the pan)
- 1 pound dry rotini pasta
- 1 block (8 ounces) cream cheese, kept whole
- 3 cups low-sodium chicken broth
- 1 1/2 pounds boneless, skinless chicken breasts, cut into bite-sized pieces
- 1 1/2 tablespoons ranch seasoning mix
- 1 teaspoon kosher salt
- 1/2 teaspoon ground black pepper
- 8 ounces sharp Cheddar cheese, freshly shredded (divided)
- 3 cups fresh broccoli florets (cut into small, bite-sized pieces)
- 1/2 cup crushed crackers or panko bread crumbs (optional, for a crunchy topping)
Step-by-Step Instructions
1. Preparation and Assembly
- Preheat your oven to 400°F (200°C).
- Grease the dish: Using the tablespoon of olive oil, thoroughly coat the bottom and inner sides of a standard 9×13-inch baking dish to prevent sticking.
- Position the base: Place the whole block of cream cheese directly in the center of the greased baking dish.
- Add the pasta: Pour the dry rotini pasta evenly around the block of cream cheese, spreading it out to cover the bottom of the pan.
- Pour the liquid: Carefully pour the chicken broth over the pasta and around the cream cheese.
2. Seasoning and Initial Bake
- Season the protein: In a medium bowl, toss the diced chicken breast pieces with the ranch seasoning mix, kosher salt, and ground black pepper until evenly coated.
- Layer the chicken: Scatter the seasoned chicken pieces evenly over the top of the pasta and broth mixture.
- Seal tightly: Cover the 9×13-inch baking dish securely with heavy-duty aluminum foil to trap the steam, which is essential for cooking the dry pasta.
- First bake: Place into the preheated oven and bake for 30 minutes.
3. Combining and Adding Vegetables
- Stir the base: Carefully remove the foil (watch out for escaping steam) and give the contents a thorough stir. The pasta will have softened, and the cream cheese will have melted into the broth to form a creamy sauce base.
- Incorporate ingredients: Stir in 1 1/2 cups of the shredded Cheddar cheese and all 3 cups of the broccoli florets directly into the pasta mixture. Smooth out the top so it is relatively flat.
- Add the topping: Sprinkle the remaining Cheddar cheese evenly over the casserole, followed by the crushed crackers or bread crumbs if you are using them for a crunchy crust.
4. Final Bake and Broil
- Second bake: Cover the dish loosely back up with foil and bake for another 15 minutes.
- Brown the top: Remove the foil entirely for the final 10 to 15 minutes of cooking. Let it bake uncovered until the cheese is completely melted, bubbling at the edges, and the topping turns a rich, golden brown.
- Rest and serve: Remove from the oven and let the casserole rest for about 5 to 10 minutes before serving. This allows the sauce to thicken up to the perfect consistency.
Chef’s Tips for Success
Shred Your Own Cheese
Pre-bagged shredded cheese often contains anti-caking agents that can make sauces grainy. Grating a block of sharp Cheddar yourself ensures a smooth, ultra-creamy melt.
Cut Broccoli Uniformly
Keep the broccoli florets small and bite-sized so they cook evenly within the limited baking time and blend seamlessly with the rotini.
Foil Seal Matters
Make sure the foil is tightly crimped around the edges of the baking dish during the first 30 minutes. This traps the steam needed to hydrate and cook the raw pasta properly in the broth.
