My kids gobbled it up without a second thought, and honestly, that’s the highest compliment I can get!

Why You’ll Love This High Protein Chicken Broccoli Alfredo Bake

It’s ridiculously easy to whip up, perfect for those weeknights when you’re short on time but still want a hearty meal. Plus, it’s packed with flavor! You get that creamy, dreamy Alfredo taste without any of the guilt. Seriously high in protein, thanks to the chicken and Greek yogurt, keeping you full and satisfied for hours. And the best part? It’s a complete meal in one dish – pasta, protein, and veggies all baked together!

Ingredients for Your High Protein Chicken Broccoli Alfredo Bake

I always use penne pasta because it holds the sauce so well, feel free to swap it for rotini or even fettuccine if you have it on hand! For the chicken, dice it small so it cooks through quickly and blends in with everything else. And trust me on the Greek yogurt; it’s my secret weapon for that creamy Alfredo texture without all the extra fat!

  • 1.5 pounds boneless skinless chicken breast, diced
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 tablespoon olive oil
  • 8 ounces penne pasta
  • 1 teaspoon salt
  • 1 cup low fat milk
  • 1 cup plain Greek yogurt
  • 0.75 cup grated parmesan cheese
  • 3 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • 1 tablespoon cornstarch
  • 2 cups broccoli florets
  • 0.5 cup shredded mozzarella cheese

Step-by-Step Instructions for Making the High Protein Chicken Broccoli Alfredo Bake

I love getting the oven preheating first thing because it means dinner will be on the table that much faster. Also, remember to cook your pasta just to al dente – it’ll finish cooking in the oven, and nobody likes mushy pasta, right? For the chicken, make sure it’s cooked all the way through; I always double-check with my trusty meat thermometer!

Step 1: Crank up your oven to 375°F and give a baking dish a light coat of cooking spray or a little oil. We want this to slide right out later, not stick!

Step 2: Grab a big pot and bring some salted water to a rolling boil. Toss in your penne pasta and cook it until it’s just about al dente – you know, with a little bite to it. During the last two minutes of cooking, throw in your broccoli florets. Drain it all well and set it aside. For more pasta tips, check out this great guide on cooking pasta.

Step 3: While the pasta is doing its thing, season your diced chicken with salt, pepper, and that lovely garlic powder. Give it a good toss so every piece gets a little flavor boost.

Step 4: Heat up your olive oil in a skillet over medium heat. Add the seasoned chicken and cook it for about 5 to 6 minutes, breaking it up with your spoon as it cooks, until it’s nicely browned and cooked all the way through. Aim for that 165°F internal temperature – no pink spots allowed!

Step 5: In a separate bowl, get ready to make your magic sauce! Whisk together the low-fat milk, plain Greek yogurt, grated Parmesan cheese, minced garlic, Italian seasoning, and cornstarch. Keep whisking until it’s super smooth and there are no lumps. This is what gives our High Protein Chicken Broccoli Alfredo Bake that signature creaminess.

Step 6: Now, in a big bowl (or you can use the pasta pot if it’s clean), combine the cooked pasta and broccoli, the browned chicken, and that dreamy Alfredo sauce. Gently mix everything until it’s all beautifully coated. Don’t be shy with the mixing!

Step 7: Pour this delicious mixture into your prepared baking dish. Sprinkle the shredded mozzarella cheese evenly over the top. It’s going to get all melty and golden!

Step 8: Pop that dish into the preheated oven and bake for about 20 to 25 minutes. You’re looking for it to be hot, bubbly, and toasty on top.

Step 9: Once it’s out of the oven, let it sit for just a few minutes before digging in. It’ll be piping hot, and this little rest helps everything settle.

Serving Suggestions for Your Chicken Alfredo Bake

To really make this High Protein Chicken Broccoli Alfredo Bake sing, I love adding a little something extra on the side. A simple fresh garden salad with a light vinaigrette is perfect for cutting through that creamy richness. Or, for a bit of a textural contrast, try some garlic bread – who doesn’t love garlic bread with pasta? If you’re feeling fancy, a sprinkle of crushed red pepper flakes right before serving adds a gentle kick that complements the Alfredo beautifully.

Storing and Reheating Your High Protein Chicken Broccoli Alfredo Bake

Leftovers? Lucky you! This High Protein Chicken Broccoli Alfredo Bake is just as delicious the next day. Store any extra portions in an airtight container in the fridge for up to 3 days. Try to keep it from sitting out too long at room temperature, for food safety reasons.

Reheating is super simple! For the best results, pop a single serving in the microwave and heat it for about 90 seconds to 2 minutes, stirring halfway through, until it’s nice and warm. If you’re reheating a bigger portion, a quick 15-20 minutes in a 350°F oven or toaster oven works wonders to get it bubbly and delicious again. It’s perfect for meal prep – just portion it out and you’ve got lunch or dinner ready to go all week!
