Ingredients
  

  • 1 pound dry spaghetti
  • 3 cups broccoli florets
  • 4 ounces cream cheese, at room temperature
  • 2 cups whole milk cottage cheese
  • 1 1/2 cups milk
  • 4 eggs, beaten
  • 1/4 cup chopped fresh parsley
  • 1/2 cup grated Parmesan cheese
  • 2 tablespoons salted butter
  • 1 pound boneless chicken breasts, cut into cubes

Instructions
 

  • Preheat the oven to 400°F. If you don’t have a deep dish oven-safe skillet, butter a large casserole dish.
  • Bring a large pot of salted water to a boil over high heat. Boil the pasta until al dente, according to package directions. During the last 2 minutes of cooking, add the broccoli. Drain, add the pasta and broccoli back into the pot.
  • Add the cream cheese, mixing it into the pasta and allowing it to melt. Now add cottage cheese, milk, eggs, parsley, and parmesan. Mix it all together until creamy.
  • Meanwhile, in a large oven-safe skillet, melt the butter with the chicken, onion, thyme, paprika, garlic powder, cayenne, salt, and pepper. Cook until golden and the butter is toasted, 5-8 minutes.
  • Mix the pasta, broccoli, and cream sauce into the chicken. Only a gentle mix is needed! Top with both cheeses. Bake 20 minutes, until the cheese is melted and beginning to brown. Serve warm with additional thyme and fresh basil.

Notes

– For best results, ensure your cream cheese is at room temperature to prevent lumps in the sauce. I once tried to rush it and ended up with tiny cheese bits, which still tasted good but wasn’t as smooth.
– To achieve a golden-brown top, you can finish the casserole under the broiler for 1-2 minutes, watching carefully to prevent burning. This also enhances the cheese pull factor.
– This casserole stores well in the refrigerator for up to 3 days. Reheat individual portions in the microwave or a larger portion in the oven at 350°F (175°C) until warmed through.

The Technique That Makes It: Creamy Emulsion and Even Baking

The success of this Cheesy Broccoli Cheddar Spaghetti Casserole hinges on creating a stable, creamy sauce that bakes evenly without becoming watery or oily. The key lies in the careful combination of dairy components and eggs to form a cohesive custard-like base. The cream cheese, softened to room temperature, is crucial for achieving a smooth, lump-free texture when combined with the cottage cheese and milk. This mixture forms the emulsion that binds the ingredients together. Cottage cheese, while adding creaminess and protein, also contributes moisture. To prevent a watery casserole, it’s important to ensure the broccoli is not overly wet; patting it dry after steaming or blanching is recommended. The beaten eggs act as a binder, setting the casserole as it bakes and preventing it from collapsing. Over-beating the eggs or adding them when the dairy mixture is too hot can lead to a scrambled egg texture within the casserole. The baking temperature of 350°F (175°C) is moderate, allowing the casserole to cook through and the custard to set without scorching the top or drying out the pasta. The butter adds richness and aids in browning, while the Parmesan cheese contributes a salty, umami depth and a slightly crisp crust.

Troubleshooting

  • Watery Casserole: Ensure broccoli is well-drained after cooking. Excess moisture from the broccoli or under-mixed dairy can lead to a watery result. Mix dairy components thoroughly until smooth before adding eggs.
  • Rubbery Pasta: Overcooked pasta before baking will result in a mushy casserole. Cook spaghetti only until al dente (about 2 minutes less than package directions) as it will continue to cook in the oven.
  • Sauce Separated or Oily: This can happen if the dairy mixture is overheated before adding eggs, or if the cream cheese wasn’t fully softened. Ensure dairy is only lukewarm when adding eggs, and cream cheese is at room temperature.
  • Dry or Crumbly Top: Insufficient dairy or overbaking can cause the top to dry out. Ensure all dairy and eggs are incorporated evenly. If the top browns too quickly, loosely tent with foil during the last 15-20 minutes of baking.

Substitutions

  • Broccoli: Frozen broccoli florets can be used; thaw and drain them very well before adding to the casserole. The texture will be slightly softer than fresh.
  • Cottage Cheese: Ricotta cheese can be substituted for cottage cheese. The resulting casserole will be slightly smoother and potentially a bit richer.
  • Milk: Half-and-half can be used instead of whole milk for a richer, creamier sauce. Light cream can also be used, but may result in a sauce that is too rich.
  • Chicken: Cooked shredded rotisserie chicken or diced ham can be used instead of fresh chicken breast for a quicker preparation. Ensure the substitute is fully cooked.

Pro tips

  • To achieve a golden-brown top, you can finish the casserole under the broiler for 1-2 minutes, watching carefully to prevent burning. This also enhances the cheese pull factor.

Frequently asked questions

Can I use frozen broccoli?

Yes, you can use frozen broccoli florets. Ensure they are completely thawed and thoroughly squeezed to remove excess water before adding them to the casserole. This step is crucial to prevent a watery final dish and maintain the desired sauce consistency.

What if I don’t have cottage cheese?

Ricotta cheese is a good substitute for cottage cheese. It will provide a similar creamy texture, though the flavor profile might be slightly milder. Ensure the ricotta is well-drained if it seems particularly wet.

Can I make this casserole ahead of time?

Yes, you can assemble the casserole up to 24 hours in advance. Cover it tightly and refrigerate. You may need to add an additional 10-15 minutes to the baking time to ensure it’s heated through completely.

How do I prevent the spaghetti from getting mushy?

Cook the spaghetti until it is just al dente, meaning it still has a slight bite. It will continue to cook in the oven as the casserole bakes. Overcooking the pasta beforehand is the primary cause of a mushy casserole.
