Looking for a fresh take on family pizza night? This Pizza Ranch Chicken Casserole is a healthier, more flavorful way to eat your pie!

Pizza Ranch Chicken Casserole

It’s CASSEROLE TIME! Once upon a time, I was in New Jersey for a stop on my book tour for Fed & Fit (the book), and I mentioned that my book had a whole chapter devoted to casseroles.That statement was met with a quiet, blank-stare response. I did NOT know that casseroles aren’t a kitchen staple everywhere! She may have been pulling my leg, but a sweet lady in the crowd asked, “is a casserole that thing from the 80’s?”

HA! Yes, yes it is…and like all good things, they have come back around. So let’s embrace a couple of the gems from the 80’s: white leather shoes and the casserole. But this time, let’s casserole a little differently.

In previous decades, casseroles were a mixture of mostly pasta with a little meat, maybe some veggie (for color, mostly), and some kind of a creamy/cheesy sauce. YES that sounds delicious to me, too …but it also sounds like a stomach ache.

You can find a good number of my healthy casseroles here on the website, including Buffalo Ranch Chicken Casserole, Chicken Caprese Casserole, and Paleo Chicken Parmesan Casserole. But I’m exceptionally excited about THIS Pizza Ranch Chicken Casserole! Here’s the breakdown.

First, we start off by adding some roasted potatoes to the bottom of a casserole dish. Then, diced tomatoes go on top, with a heavy sprinkle of Italian seasoning. You can think of this like the pizza crust + sauce! The potatoes represent the crust and tomatoes …well, you get it.

From there, things get especially tasty. Because chicken is the protein star of this show, I wanted to dress it up. I’m that girl who always dips her pizza in ranch dressing, so ranch was an obvious flavor choice. 

That chicken gets tossed in a liberal amount of the ranch, then spread over our “pizza crust.” Pepperoni is layered over the chicken to be followed by YOUR favorite pizza toppings. I chose green pepper, black olives, and mushrooms. Into the oven it goes until the toppings look crisp! Sprinkle the top with crushed red pepper and ENJOY this pizza ranch chicken casserole!

How to Make Pepperoni Pizza Casserole

Loaded with pepperoni, mushrooms, olives, and peppers, here’s how this pepperoni pizza casserole comes together. 

Seasoned cubes of potato are tossed onto a lined tray on a light grey surface.
Golden chicken tenders sit in a stainless steel frying pan on a light grey surface.

Step 1: Toss the potatoes with the olive oil, salt, pepper, and garlic powder, then spread out on a rimmed baking sheet lined with parchment paper. Bake for 30 minutes until crisp, then remove from the oven and reduce heat to 350 F.

Step 2: While the potatoes are cooking, add the olive oil to a large pan over medium heat. Season the chicken liberally on both sides with the salt and pepper. Working in two batches, add the chicken to the pan with the olive oil. Sear for 5 minutes on one side, then turn over and sear for 2 minutes on the other side.

Ranch dressing sauce is stired through cubes of cooked chicken on a light grey surface.
Herbs and spices are tossed into a shallow bowl with diced tomatoes on a light grey surface.

Step 3: Once the chicken is finished cooking, cut into 1-inch pieces, then toss with the pizza ranch dressing. Set aside.

Step 4: Toss the drained diced tomatoes with the Italian seasoning and garlic powder, then set aside.

Slices of green bell pepper sit on top of a pizza ranch chicken casserole on a light grey surface.

Step 5: To assemble the casserole: place the potatoes in the bottom of a round casserole dish, then top with the tomato mixture, followed by the ranch chicken mixture. Next, place the pepperonis on top of the chicken, then add the mushrooms, olives, and green bell pepper, making sure they are evenly spread out.

Step 6: Bake at 350 F for 30 minutes, let cool slightly, and serve with additional pizza ranch on the side!

Recipe Tip

Tomatoes – be sure to drain the canned tomatoes really well before adding them to the casserole dish. Too much liquid will take some of the crispiness out of the roasted potatoes.

How to Serve

Serve this pizza piping-hot, with extra ranch on the side!

How to Store and Reheat

Store the pizza in the casserole dish you baked it, covered, for up to 3 days. 

To reheat it, just pop it back in the oven and bake at 425 F until warmed through.

    Loved this! Its so good. I added more peppers and onions as toppings along with bacon and a little cheese!

    1. I’m so glad, Kylie! Thank you for sharing this with us!

  2. Would you mind putting in the recipe what type of pan/dish would work best and maybe an alternative pan? I find myself having to guess sometimes which pan would work best. Love your recipes! Thank you for making the weekly meal plan.

    1. Of course — sorry about that, Heather! Any casserole dish is a great choice here. Hope you enjoy this one!

    1. Thanks for catching that, Coby! It should be tenders, not thighs!

  3. 5 stars
    This is an amazing and easy dish that my whole family loves! Very filling and tastes amazing!

    1. YAY…so glad that your whole family loves it, Mandy! We love it too!!

  4. Anyone made this ahead of time and then bake later? Wondering how it would hold up if it was ready to go the night before it needed to be served?

  5. 5 stars
    Another big win for the Fed and Fit team! Made this last night (in a 9×13 dish – worked perfectly) because the fresh green peppers from the garden needed a home! SO GOOD!

  6. This looks amazing, I cannot wait to try it! Quick question though, I only have an 8×8 and a 9×13 casserole dish. Which size would work best for this, I’m not sure how big your round one. I hope I didn’t miss something when I read your blog…I hate it when people ask already answered questions! 😉

    Thanks Cassy!!
