Chicken and Broccoli Baked Alfredo
Some nights, the only thing that will do is a big, warm, comforting bowl of something cheesy. You know the kind of day I’m talking about. The one where everything feels a little too hectic and your brain is just a little too tired.
On those days, I pull out this recipe. It’s my secret weapon against the chaos. It feels like a hug in a casserole dish.
This isn’t just another pasta bake. It’s a creamy, dreamy Chicken and Broccoli Baked Alfredo that tastes like it came from a cozy Italian restaurant, but it’s shockingly simple to make right in your own kitchen.
We’re talking tender chicken, perfectly cooked broccoli, and a rich, velvety Alfredo sauce all baked together under a blanket of golden, bubbly cheese. It’s the kind of meal that makes everyone at the table go quiet for the first few bites. Let’s get into it.
What You’ll Need
Here’s the simple lineup of ingredients. Nothing too wild, just pure, wholesome goodness that comes together beautifully.
- 1 lb boneless, skinless chicken breasts, cut into 1-inch cubes
- 12 oz penne pasta (or another short pasta)
- 1 large head of broccoli, cut into bite-sized florets
- 4 tablespoons unsalted butter
- 4 cloves garlic, minced
- 2 cups heavy cream
- 1 cup freshly grated Parmesan cheese, plus more for topping
- 1/2 cup shredded mozzarella cheese
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon nutmeg (optional, but recommended)
- 2 tablespoons olive oil
Tools Required for the Job
You don’t need a professional kitchen setup for this. Here are the basic tools that will make the process smooth and easy.
- Large pot (for pasta and broccoli)
- Large oven-safe skillet or a separate skillet and a 9×13 inch baking dish
- Whisk
- Cutting board
- Sharp knife
- Colander
Pro Tips for a Perfect Bake
I’ve made this dish more times than I can count, and I’ve picked up a few tricks along the way. These little details make a big difference.
1. Under-Cook Your Pasta (Seriously): Your pasta is going to continue cooking in the oven while it soaks up that amazing sauce. Cook it for about 2 minutes less than the package directions for al dente. This prevents it from turning into mush and ensures the perfect texture in the final dish.
2. Use Freshly Grated Parmesan: I can’t stress this enough. The pre-shredded cheese in a bag contains starches and anti-caking agents to keep it from clumping. These additives can make your Alfredo sauce grainy. A block of Parmesan and a grater is your best friend for a silky smooth sauce.
3. Don’t Skip the Nutmeg: It might sound a little strange, but a tiny pinch of nutmeg is a classic addition to cream sauces. You won’t really taste it, but it enhances the creamy, savory flavors and adds a warmth that you just can’t get otherwise. It’s a secret ingredient that makes people ask, “What is in this? It’s amazing!”
4. Let It Rest: Once you pull that beautiful, bubbly casserole out of the oven, give it a moment. Let it rest on the counter for 5 to 10 minutes before you dig in. This allows the sauce to set up and thicken slightly, so it clings to the pasta instead of pooling at the bottom of the dish.
Step-by-Step Instructions
Alright, let’s build this masterpiece. Follow these simple steps, and you’ll be on your way to pasta perfection.
Step 1: Prep and Cook Pasta
Preheat your oven to 375°F (190°C). Cook the penne according to package directions, but make sure to pull it out about 2 minutes early so it’s very al dente. In the last 2 minutes of cooking, toss the broccoli florets into the pasta water to blanch them. Drain everything together in a colander.
Step 2: Cook the Chicken
While the pasta cooks, heat olive oil in a large oven-safe skillet over medium-high heat. Season the chicken cubes with salt and pepper. Add the chicken to the skillet and cook until it’s golden brown and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set it aside.
Step 3: Make the Alfredo Sauce
In the same skillet, melt the butter over medium heat. Add the minced garlic and cook for about 30 seconds until fragrant, being careful not to burn it. Slowly pour in the heavy cream, whisking constantly. Bring it to a gentle simmer.
Step 4: Thicken the Sauce
Reduce the heat to low. Gradually whisk in the 1 cup of freshly grated Parmesan cheese until the sauce is smooth. Stir in the salt, pepper, and a pinch of nutmeg. Let it simmer gently for another 2-3 minutes to thicken up.
Step 5: Combine Everything
Add the cooked pasta, broccoli, and chicken back into the skillet with the sauce. Stir gently until everything is evenly coated in creamy goodness.
Step 6: Bake to Perfection
Sprinkle the shredded mozzarella and a little extra Parmesan cheese over the top. If your skillet isn’t oven-safe, transfer the mixture to a 9×13 inch baking dish first. Bake for 15-20 minutes, or until the sauce is bubbly and the cheese on top is melted and slightly golden.
Step 7: Rest and Serve
Remove from the oven and let it rest for 5-10 minutes before serving. This is the hardest part, but it’s worth the wait!
Substitutions and Fun Variations
This recipe is a great starting point. Feel free to play around with it based on what you have or what you’re in the mood for.
| Component | Try This Instead | Notes |
|---|---|---|
| Chicken Breast | Shrimp or Italian Sausage | Cook shrimp just until pink. Brown sausage well. |
| Broccoli | Spinach, Peas, or Mushrooms | Wilt spinach first. Sauté mushrooms for best flavor. |
| Penne Pasta | Fettuccine, Ziti, or Rotini | Any pasta that can hold a thick sauce works well. |
| Heavy Cream | Half-and-Half | Sauce will be less rich, but still delicious. |
Healthier Swaps & Serving Ideas
Want to lighten it up or figure out what to serve it with? I’ve got you covered.
For a Lighter Meal: You can substitute the heavy cream with half-and-half or even whole milk, but be aware the sauce will be thinner. To boost the veggies, add in some sautéed mushrooms, bell peppers, or wilted spinach.
Gluten-Free Option: This is an easy one! Just swap the regular pasta for your favorite brand of gluten-free penne or rotini. The rest of the ingredients are naturally gluten-free.
What to Serve Alongside: This dish is a full meal on its own, but a simple side salad with a bright vinaigrette cuts through the richness beautifully. And of course, you can never go wrong with a side of warm garlic bread for soaking up every last bit of that sauce.

Make-Ahead and Storage Tips
Life gets busy, and sometimes you need to prep things in advance. This casserole is perfect for that.
Make-Ahead: You can assemble the entire casserole up to the point of baking. Just follow all the steps, put it in your baking dish, let it cool completely, then cover it tightly and refrigerate for up to 24 hours. When you’re ready to eat, you may need to add 10-15 minutes to the baking time since it’s starting cold.
Leftovers and Storage: Store any leftovers in an airtight container in the refrigerator for up to 4 days. The sauce will thicken as it cools. When reheating, you can add a splash of milk or cream to loosen the sauce up a bit. The oven or a toaster oven is best for reheating to keep that nice texture.
Frequently Asked Questions
Here are answers to a few questions that often come up when making this dish.
Q1. Can I use frozen broccoli instead of fresh?
Ans: Yes, you can. I recommend thawing it completely first and then patting it very dry with paper towels. Excess water can make your sauce thin. You can skip the blanching step and just add it in with the pasta and chicken.
Q2. My sauce seems too thin. What did I do wrong?
Ans: Nothing! Sometimes it just needs a little more time. Let it simmer on low for a few more minutes, whisking occasionally. The Parmesan cheese is the main thickener, so make sure you’ve added the full amount. Remember, it will also thicken up as it bakes and as it rests.
Q3. Can I freeze the entire baked alfredo?
Ans: You can, but with a word of caution. Dairy-based sauces can sometimes separate or become grainy after freezing and thawing. For the best results, I’d recommend freezing it *before* baking. Assemble the dish, cover it tightly with plastic wrap and foil, and freeze for up to 3 months. Thaw it overnight in the fridge before baking as directed.
Q4. Can I use a different kind of cheese?
Ans: Absolutely. While Parmesan is classic for Alfredo, you could blend in some Asiago or Romano for a sharper flavor. For the topping, a mix of provolone and mozzarella would be delicious and give you a great “cheese pull.”
