The Picky Eater Who Couldn’t Resist

My nephew, a notorious picky eater (think “only eats plain noodles and chicken nuggets”), surprised us all when he went back for seconds of this casserole. His mom stared in disbelief as he happily scooped up bites with onions, veggies, and all. The magic? The creamy ranch-seasoned sauce and buttery Ritz cracker topping won him over. If that’s not a stamp of approval, I don’t know what is!

What Makes It Special

✨ Creamy, dreamy sauce – A mix of cream of chicken soup, sour cream, and ranch seasoning creates a rich, flavorful base.

✨ Golden, crispy topping – Buttery crushed Ritz crackers add the perfect crunch.

✨ Rotisserie chicken shortcut – Pre-cooked chicken saves time without sacrificing flavor.

✨ Hash browns for the win – They soak up the sauce while staying tender inside and slightly crisp on the edges.

✨ Hidden veggies – Frozen mixed veggies add nutrition without overpowering the dish.

Making It Happen

Let’s turn these simple ingredients into a show-stopping casserole!

Prep & Preheat – Start by heating your oven to 350°F and greasing a 9×13-inch baking dish to prevent sticking.
Mix the Sauce – In a large bowl, whisk together cream of chicken soup, sour cream, milk, and ranch seasoning until smooth and creamy.
Fold in the Good Stuff – Add thawed hash browns, diced onions, shredded cheddar cheese, cooked chicken, and frozen mixed veggies. Stir until everything is well coated in that luscious sauce.
Layer & Top – Spread the mixture into your prepared dish. In a small bowl, mix crushed Ritz crackers with melted butter, then sprinkle this crispy goodness evenly over the top.
Bake to Perfection – Slide the casserole into the oven and let it bake for about 1 hour, or until the top is golden brown and the filling is hot and bubbly.
Serve & Savor – Let it cool for a few minutes, then dig in while it’s warm and gooey!

You Must Know: Pro Tips for Success

🔥 Thaw hash browns first – Frozen hash browns can make the casserole watery if not thawed.

🔥 Use full-fat dairy – Low-fat sour cream or milk can make the sauce less creamy.

🔥 Customize the crunch – Swap Ritz crackers for crushed potato chips, cornflakes, or panko breadcrumbs.

🔥 Let it rest – Allow the casserole to sit for 5–10 minutes after baking for easier slicing.

🔥 Double the batch – This freezes well, so make two and stash one for later!

Serving Ideas

🍽 Pair with a crisp green salad, roasted Brussels sprouts, or garlic bread.

🥂 Drink pairing – A chilled glass of Chardonnay or sparkling water with lemon balances the richness.

Make It Different: Customizations

🌶 Spice it up – Add diced jalapeños or a dash of hot sauce for heat.

🍗 Turkey swap – Use leftover Thanksgiving turkey instead of chicken.

🥦 Veggie-loaded – Toss in extra broccoli, bell peppers, or mushrooms.

🧀 Cheese lovers – Mix in pepper jack or mozzarella for extra gooeyness.

🥓 Meatier version – Crumble cooked bacon on top before baking.

Storage & Reheating Tips

❄️ Fridge – Store leftovers in an airtight container for up to 3–4 days.

🔥 Reheat – Warm in the oven at 350°F for 15–20 minutes (microwaving can make the topping soggy).

⏲ Freeze – Wrap tightly and freeze for up to 2 months. Thaw overnight before reheating.

Success Tips

✔ Don’t overmix – Gently fold ingredients to keep hash browns intact.

✔ Check for doneness – The casserole should be bubbling at the edges when ready.

✔ Fresh vs. frozen – Fresh diced potatoes can work but may need longer baking.
