Dump and Bake Chicken Alfredo: 1 Pan, 10-Min Prep

On a busy night in the week I choose Dump and Bake because it is hands off. This Chicken Alfredo Casserole is my go-to comfort food for dinner since it is cheesy and the entire family can enjoy it.

There is no need to boil the pasta because a jar of alfredo sauce and rotisserie chicken make it one of the quickest meals to prep in 10 minutes from start to oven. Just dump, mix, and bake with no work to make or clean up, and it turns out delicious and perfect.

Dump and Bake Chicken Alfredo-The Short Answer

I keep it a weeknight staple with Chicken seasoned with Italian herbs, layered with dry pasta, broccoli, and a simple homemade Alfredo-style sauce. I sprinkle cheese and extra garlic on top, bake until bubbling and golden, then finish with grated parmesan and fresh parsley for a fresh Noodle-style casserole.

Why Is It Easy?

• A dump and bake recipe like chicken alfredo casserole is something my family loves for classic flavors, sauce, and cheese.
• I add ingredients to a baking dish, stir, and place it in the oven with very little prep time, just minutes max, I promise.
• The oven does the work, giving a creamy, cheesy, delicious meal that tastes like I spent hours slaving away.
• On busy weeknights, these recipes are ideal since everything gets dumped into a 9×13 pan, sheet, skillet, or slow cooker and cooks together until done.
• With little effort needed, I skip bowls, pans, cutting boards, and knives, and still put something comforting and homemade on the table.
• I make elaborate meals easily, relying on them the most, making cozy dishes on repeat through fall and winter all year long.

Ingredients

Base Ingredients

• I start with uncooked Penne or pasta, dumped straight into a casserole dish with no need to boil beforehand
• I use two jars of Alfredo Sauce—my favorite bertolli brand as an inexpensive option, or Rao’s for a more expensive but really good result worth the pay
• You can use the same kind or switch, pick a different flavor like roasted garlic alfredo sauce
• I always recommend adding Chicken Stock or Broth, making sure it’s full and salted, so the recipe doesn’t turn bland and still has proper salt and flavor

Protein & Vegetables

• I use Cooked Shredded Chicken—either rotisserie, leftover from a meal, or frozen breasts cooked in a slow cooker or instant pot, even a can works
• Add Fresh Broccoli, one head (about cups), cut into small florets
• Season with Italian seasoning, garlic powder, kosher salt, black pepper, plus other dried seasonings
• Finish with Mozzarella Cheese or an Italian Blend for better melt and texture

Extras & Adjustments

• Use a box of 16 oz penne or short pasta like spirals, along with 15 or 22 jar sauce depending on how creamy you want it
• Adjust liquid using cup measures like 1/2 cup of chicken stock, broth, milk, or heavy cream
• For richness, add 2 tablespoons of butter (melted), 1-2 spoons using teaspoon or tsp of minced garlic, plus a hint of onion
• Add extra protein with boneless pound chicken cut into cubes, and optional chili flakes for heat
• You can also mix in dry options like egg noodles or keep using short pasta
• Finish with 3 to 4 ounces of cream cheese, plus grated Parmesan or provolone, and garnish with parsley or basil before serving

Instructions

Prep and Mix

• Set your oven and preheat to 425℉ 
• Grease a 9×13 casserole dish with cooking spray
• Add ingredients: penne pasta (box 16 oz) alfredo sauce (jars 15 oz) chicken stock or broth cooked shredded chicken chopped fresh broccoli
• Season with a teaspoon of Italian seasoning garlic powder kosher salt black pepper
• Stir until mixed, then cover tightly with tin foil and bake 35-45 minutes for desired texture

Check and Adjust

• Uncover, stir, and check the pasta for al dente (firm tender bite, not hard)
• If needed return to the oven, cover, and continue to cook
• I usually pour a little water or extra stock with uncooked pasta for even cooking and a slightly crispy top

Finish and Serve

• Sprinkle mozzarella or cheese blend over the top
• Place under the broiler until melted golden brown browning
• Optional: melt butter with onion and chili flakes or mix cream cheese heavy cream milk parmesan, then whisk and pour evenly over noodles and broccoli
• Add freshly grated Parmesan parsley basil garnish, let it set, then scoop serve warm enjoy

Shelf Life

From my experience, How To handle leftovers is easy: you can store them inside the casserole dish or as individual servings in airtight containers, then place them in the fridge for up to 4 days; just Reheat the leftovers inside the microwave, and I always store Any extra this way.

For Better Results

• I always cook this recipe with a good brand of alfredo so the taste shines through the casserole; I usually buy bertolli, but I love rao’s even if it’s expensive.
• Use fresh cheese or a bag of pre-shredded italian blend; both does well based on what you prefer, and I add seasoning like dried basil, parsley, chili, pepper flakes for spice.
• Adjust salt since broth or stock can be saltier; I recommend using kosher salt, about a teaspoon or less, then make changes, try, and see your taste.
• Covering the pan with foil is a must to keep hot air inside and help the pasta soften as it bake.
• A 45 minute cook time will yield a softer dish; less, closer to minutes like 35 gives firmer, al dente results.
• I’ve only ever used fresh broccoli since frozen adds too much liquid during thawing and cooking, causing crisping or burning.
• My family and kids likes it soft, so I always make it blend well; you can add more, adjust each, pick any variety, or instead test until the content feels right—I’ve learned in my own kitchen I normally say small tweaks help, and I don’t mind trying again because I prefer what works and keep improving what I would serve.

I read this recipe from The Seasoned Mom, knew I had to give it a try, and now it’s my favorite go-to for busy nights when I just don’t have time to cook dinner—LOL, no one would ever know how easy, delicious, this little dish it is.
