This Chicken Alfredo Casserole is basically your culinary BFF. It’s so easy, I’m pretty sure my cat could supervise the process (if she wasn’t so busy napping).

Ingredients You’ll Need
Gather ’round, my lazy-gourmet pals! Here’s what you need for this masterpiece. Don’t worry, it’s all stuff you probably have or can grab without a treasure hunt.
- **1 lb short pasta:** Think penne, rotini, or farfalle. Whatever calls to your soul (or is lurking in your pantry).
- **2 cups cooked chicken, shredded or diced:** Rotisserie chicken is your absolute best friend here. No shame in that game!
- **2 (15 oz) jars Alfredo sauce:** Yes, jarred! We’re all about convenience today. Don’t let anyone judge your shortcuts.
- **1 cup whole milk (or half-and-half):** To loosen things up and add extra creaminess.
- **1/2 cup grated Parmesan cheese:** For that salty, nutty kick.
- **2 cups shredded mozzarella cheese:** Because is it even a casserole without a glorious cheese pull? Nope.
- **2 cups fresh spinach:** Optional, but it adds a nice pop of color and, dare I say, a whisper of health. You do you.
- **1 tbsp olive oil (or butter):** For a little sauté action.
- **2-3 cloves garlic, minced:** Because garlic makes everything better, **IMO**.
- **Salt and freshly ground black pepper:** To taste, darling, always to taste.
Step-by-Step Instructions
Alright, apron up (or don’t, I won’t tell) and let’s get this deliciousness going!
- **Cook the Pasta:** Get a big pot of salted water boiling. Toss in your chosen pasta and cook according to package directions until al dente. **Don’t overcook it!** Nobody wants mushy pasta. Drain it like a champ and set aside.
- **Preheat and Prep:** While the pasta’s doing its thing, preheat your oven to 375°F (190°C). Grab a 9×13 inch casserole dish and give it a quick spray with cooking spray. Your future self will thank you for not scrubbing stuck-on cheese.
- **Garlic Sizzle:** Heat the olive oil (or butter) in a large pan over medium heat. Add the minced garlic and sauté for about 30-60 seconds until it’s fragrant. **Don’t burn it!** Burnt garlic is a sad, bitter thing.
- **Sauce it Up:** Pour in both jars of Alfredo sauce and the milk. Stir it all together until it’s smooth and heated through. Add the Parmesan cheese and stir until melted. This is where the magic begins!
- **Combine the Goodness:** Dump the cooked pasta, shredded chicken, and fresh spinach into the sauce. Stir everything gently until the spinach wilts and all the ingredients are coated in that glorious, creamy sauce.
- **Into the Dish:** Pour the entire mixture into your prepared casserole dish. Spread it out evenly.
- **Cheese Time!** Sprinkle that beautiful mozzarella cheese generously over the top. Feel free to add more if you’re feeling extra cheesy (you always should be).
- **Bake Away:** Pop it into the preheated oven for 20-25 minutes, or until the casserole is bubbly around the edges and the cheese on top is melted and golden brown. If you want extra browning, give it a quick broil for a minute or two at the end (keep an eye on it!).
- **Rest and Serve:** Let it rest for 5-10 minutes before serving. This helps the sauce set up a bit and prevents it from being a molten lava mess when you scoop it. Garnish with some fresh parsley if you’re feeling fancy.
Common Mistakes to Avoid
Even the easiest recipes have pitfalls. Learn from my past mistakes, so you don’t have to!
- **Overcooking the Pasta:** I said it once, I’ll say it again: mushy pasta is a tragedy. Cook it al dente, because it’ll continue to cook a little in the oven.
- **Forgetting to Salt the Pasta Water:** This is literally your only chance to season the pasta itself. **FYI**, it makes a huge difference in flavor. Don’t skip it!
- **Burning the Garlic:** Garlic goes from fragrant to burnt in 0.2 seconds. Keep an eye on it and keep the heat moderate.
- **Not Preheating the Oven:** Thinking you can just throw it in a cold oven is a rookie mistake. It messes with baking times and the overall texture.
- **Skimping on Cheese:** Don’t be shy with the cheese on top! It’s the crown jewel of any casserole.
Alternatives & Substitutions
Feeling adventurous or just working with what you’ve got? No problem, this recipe is super flexible!
- **Chicken Swap:** Not a fan of chicken? Use cooked shrimp, leftover turkey, or even Italian sausage. For a veggie version, omit the meat entirely or add some sautéed mushrooms.
- **Pasta Choices:** Gluten-free pasta works wonderfully here. You could also use egg noodles if that’s what’s calling your name.
- **Veggies Galore:** Don’t stop at spinach! Add sautéed mushrooms, broccoli florets, peas, or bell peppers for extra flavor and nutrients. Just make sure they’re cooked tender-crisp before adding to the mix.
- **Cheese Switch-Up:** No mozzarella? Use provolone, a mixed Italian blend, or even cheddar for a different vibe. A sprinkle of red pepper flakes on top adds a nice little kick!
- **Homemade Alfredo:** If you’re feeling extra, you can totally make your own Alfredo sauce from scratch. Butter, heavy cream, garlic, and Parmesan are your main players. But remember, the jarred stuff is perfectly acceptable for an “easy” recipe!
FAQ (Frequently Asked Questions)
Got questions? I’ve got answers (and maybe some sass).
Can I use rotisserie chicken? Um, **absolutely!** That’s the *ultimate* hack for this recipe. It saves so much time and adds great flavor.
Can I make it ahead of time? You betcha! Assemble the entire casserole (without baking), cover it tightly with foil, and refrigerate for up to 24 hours. When you’re ready to bake, you might need to add an extra 10-15 minutes to the baking time if it’s going in cold from the fridge.
How long do leftovers last? If it even *makes it* past dinner, you’re doing well! Kidding (mostly). Store leftovers in an airtight container in the fridge for 3-4 days.
Is it freezer friendly? Yep! You can freeze the baked casserole (cool it completely first) in an airtight, freezer-safe container for up to 2-3 months. Thaw in the fridge overnight before reheating, or reheat from frozen at a lower temperature until warmed through.
Do I have to use spinach? Nah, it’s optional. But it adds a nice pop of color and, let’s be honest, helps us pretend we’re eating super healthy. If you don’t like spinach, skip it!
My Alfredo sauce is too thick. What should I do? Add a little more milk or chicken broth, a tablespoon at a time, until it reaches your desired consistency. Different brands of jarred sauce can vary.
Can I add bacon? Is that even a question? Of course you can! Crispy crumbled bacon bits mixed in or sprinkled on top would be glorious. You’re welcome.
