There are 13 white bowls and small dishes filled with different items: diced cooked chicken pieces in one large bowl, white chopped onions in another medium bowl, pale yellow uncooked penne pasta in a large bowl, chopped green celery in a smaller bowl, and a mix of frozen vegetables with orange carrots, green peas, and more in another bowl. Other small bowls contain off-white breadcrumbs, pale yellow butter, creamy white sour cream, light yellow olive oil, a small amount of chopped green herbs, and a glass with white milk.

This toss-together casserole relies on wholesome, easy-to-find ingredients that each play a special role. The mini penne brings just the right bite to soak up all the creamy sauce, while tender chicken and mixed vegetables add heartiness and color. The Parmesan cheese on top gives a salty, nutty finish that elevates the entire dish.

Mini penne pasta: Its small size makes it perfect for baking and for capturing sauce in every bite.
Frozen mixed vegetables: Add color, texture, and mild sweetness without extra prep.
Butter and extra-virgin olive oil: These combine for a rich sauté base that builds flavor.
Chopped onion and diced celery: Provide a subtle crunch and aromatic depth to the sauce.
Dried parsley and black pepper: Light seasoning to brighten and balance the rich creaminess.
Diced cooked chicken: The hearty protein star that makes this casserole a complete meal.
Condensed cream of chicken soup: Acts as the creamy binder, enhancing the savory flavor.
Milk and sour cream: Add silkiness and tang to make the sauce irresistible.
Kosher salt: Essential for bringing all the flavors together perfectly.
Freshly shredded Parmesan cheese: Creates that golden, bubbly topping everyone loves.

Directions

Step 1: Begin by gathering all your ingredients on the counter to streamline the cooking process.

Step 2: Preheat your oven to 350 degrees Fahrenheit and grease a 2-quart casserole dish thoroughly—this keeps the mashed-together goodness from sticking.

Step 3: Boil the mini penne pasta in salted water according to the package directions until just al dente. Once cooked, rinse the pasta under cold water to stop the cooking process and drain well.

Step 4: Cook the frozen mixed vegetables following the package instructions, drain, and set them aside so they’re ready to mix in.

Step 5: In a medium saucepan over medium heat, melt the butter together with the extra-virgin olive oil. Add the onion and celery, stirring frequently until the vegetables become tender and fragrant, about 5-7 minutes.

Step 6: Stir in the dried parsley and freshly ground black pepper, then add the diced cooked chicken, condensed cream of chicken soup, milk, sour cream, and the cooked vegetables. Mix everything thoroughly and take a taste—add kosher salt if needed to perfect the seasoning.

Step 7: Fold the drained penne pasta gently into the sauce mixture ensuring every piece is coated.

Step 8: Transfer the mixture into your prepared casserole dish, spreading it out evenly. Sprinkle the top generously with the shredded Parmesan cheese to create that irresistible golden crust.

Step 9: Bake uncovered for 30 to 40 minutes or until the casserole is hot, bubbly, and the cheese topping turns a lovely golden brown.

Servings and Timing

This Creamy Chicken and Mini Penne Casserole Recipe comfortably serves six hearty portions, making it ideal for feeding a family or having leftovers. Prep time is delightfully quick at around 15 minutes. The total cook time, including baking, is approximately 45 minutes, so you’re looking at about one hour from start to finish. There’s no special resting time needed—this casserole is best enjoyed hot and fresh from the oven!

Personally, I love serving this casserole piping hot and straight from the oven. It pairs beautifully with crisp, fresh side salads or a simple plate of steamed greens to balance the richness. Some lightly sautéed green beans or roasted asparagus also work wonders alongside the dish, adding just enough crunch and brightness. When plating, I like using shallow bowls to cradle the creamy sauce and portioning about one to one-and-a-half cups per person, making sure everyone gets a satisfying scoop.

For garnishes, a sprinkling of fresh chopped parsley or basil adds a pop of color and fresh herbaceous notes that make each bite feel special. I sometimes add a grating of extra Parmesan on top just before serving for that little extra cheesy touch. This casserole is perfect for cozy family dinners, casual weekend lunches, or even holiday potlucks where everyone is craving something filling and comforting. No matter the occasion, it’s such a crowd-pleaser that I always make sure to have it on my recipe list.

If you’re wondering about temperature, I find it’s most delicious hot or warm, as the cheese is nice and melty. You can also serve it at room temperature if needed, although a quick reheating in the oven or microwave really brings back the creamy goodness wonderfully.

Variations

I enjoy experimenting with this Creamy Chicken and Mini Penne Casserole Recipe to suit different tastes or dietary needs. For example, you can swap the Parmesan cheese for a shredded cheddar or a mozzarella blend to switch up the flavor profile—cheddar gives a sharper bite, while mozzarella keeps things gooey and mild. If you want a little crunch on top, sprinkling fine breadcrumbs mixed with melted butter over the cheese before baking adds a delightful texture contrast.

If you prefer to customize the veggies, I’ve had great success using chopped broccoli, sautéed spinach, or even artichoke hearts in place of the frozen mixed vegetables. For a vegetarian twist, you can simply skip the chicken and substitute the condensed soup with cream of celery or mushroom soup, making the casserole lighter but still creamy and delicious.

For those needing gluten-free options, I recommend gluten-free mini pasta which is widely available, along with checking that the soup and other packaged ingredients are gluten-free. In terms of cooking methods, while I always bake this casserole, you could assemble it and cook it in a slow cooker on low for a few hours if you want a hands-off approach. Just be sure to keep an eye on the moisture levels so it doesn’t dry out.

Storage and Reheating

Storing Leftovers

After enjoying your casserole, any leftovers should be transferred to an airtight container to maintain freshness. I like using glass or BPA-free plastic containers with tight-fitting lids to keep everything sealed properly. Stored in the refrigerator, this casserole will stay good for up to 3-4 days, making it perfect for easy next-day meals.

Freezing

This creamy casserole freezes very well if you want to prepare it ahead of time or save portions for later. I usually let it cool completely before transferring portions or the entire casserole into freezer-safe containers or heavy-duty zip-top bags. Labeling them with the date helps keep track, and it will keep in the freezer for up to 2-3 months without losing flavor or texture.

Reheating

When it’s time to reheat, the oven is my preferred method for preserving that lovely cheese crust and creamy texture. Heat at 350 degrees Fahrenheit for about 20-25 minutes until warmed through, covering loosely with foil if it looks like it might brown too fast. Microwaving works too for quick reheats—just cover and heat in short intervals, stirring gently to distribute heat evenly. Avoid overheating to prevent drying out the sauce.

FAQs

Can I use raw chicken in this casserole?

No, I strongly recommend using cooked chicken. Since the casserole bakes for a relatively short time, using raw chicken could result in undercooked meat. Cooking chicken beforehand ensures safety and delivers tender, flavorful bites.

What can I substitute for the condensed cream of chicken soup?

You can make a homemade cream sauce using butter, flour, and milk seasoned with chicken broth or simply use cream of celery or mushroom soup as alternatives. These options keep your casserole creamy while offering a slightly different flavor profile.

Is there a way to make this recipe dairy-free?

Absolutely! You can swap the butter for dairy-free margarine or olive oil, use plant-based milk such as almond or oat milk combined with a dairy-free sour cream alternative, and choose a vegan cheese substitute for the topping. This way, you’ll enjoy a similar creamy texture without any dairy.

Can I prepare this casserole in advance and bake later?

Yes! You can assemble the entire casserole and refrigerate it for up to 24 hours before baking. This makes it an excellent dish for meal planning or entertaining guests. Just add a few extra minutes to the baking time if it comes straight from the fridge.

What side dishes go well with this casserole?

I love pairing it with crisp salads, steamed green vegetables, or garlic bread. These sides help cut through the richness and bring freshness and varied texture to your meal.

Conclusion

I truly hope you give this Creamy Chicken and Mini Penne Casserole Recipe a try because it’s such a rewarding and satisfying comfort food. Every time I make it, it feels like a celebration of simple ingredients turned into something delightfully warm and creamy.
