Step-by-Step Cooking Guide
Prepare the Pasta and Broccoli
Bring a large pot of salted water to a boil. Cook the high-protein pasta until it is just shy of fully cooked.
During the last two minutes, add the broccoli florets directly to the pasta water.
Drain everything together.
Tip: Al dente pasta is essential. Overcooked pasta can become soft after baking.
Make the Alfredo Sauce
Melt butter in a large saucepan.
Add minced garlic and stir for about 30 seconds until fragrant. Avoid browning the garlic, which can create bitterness.
Pour in the chicken broth and milk, whisking continuously.
Add softened cream cheese and stir until completely smooth.
Lower the heat and gradually whisk in Greek yogurt and Parmesan cheese.
Season with salt, pepper, and nutmeg.
Tip: If the sauce seems thick, add a few tablespoons of milk until you reach your preferred consistency.
Combine Everything
In a large mixing bowl, combine cooked pasta, broccoli, diced chicken, and Alfredo sauce.
Gently fold everything together until evenly coated.
Tip: Every piece of pasta should have a light coating of sauce before transferring to the baking dish.
Assemble and Bake
Transfer the mixture to a lightly greased baking dish.
Sprinkle mozzarella and Parmesan evenly over the top.
Bake until bubbling around the edges and lightly golden on top.
Allow the casserole to rest for 5 minutes before serving.
Tip: Resting helps the sauce thicken slightly, making serving easier.
