Step-by-Step Instructions
Step 1: Prep the oven and baking dish
Arrange a rack in the middle of the oven and preheat to 375°F (190°C). Lightly grease a 9 x 13-inch baking dish with butter or nonstick spray.
This recipe bakes up creamy and bubbly, so a deeper dish helps prevent overflow if your sauce simmers extra thick.
Step 2: Cook the pasta just shy of al dente
Bring a large pot of water to a boil. Add 1 tbsp kosher salt, then add the 12 oz penne.
Cook for 2 minutes less than the package directions for al dente (it will finish cooking in the oven). Drain well.
Step 3: Start the creamy base (roux + milk)
While the pasta cooks (or right after), melt 4 tbsp butter in a large pot or deep skillet over medium heat.
Whisk in 2 tbsp flour and cook, whisking constantly, for 1 minute. This cooks out the raw flour taste and sets you up for a smooth sauce.
Slowly whisk in 2 cups whole milk. Bring to a gentle simmer and cook for 3 to 5 minutes, whisking often, until the sauce thickens enough to lightly coat a spoon.
Step 4: Turn it into Buffalo-style creamy sauce
Lower the heat to medium-low. Add the 4 oz cream cheese and whisk until melted and smooth.
Whisk in 1/2 cup hot sauce and 1/2 cup ranch dressing. Season with 1/2 tsp garlic powder, 1/2 tsp onion powder, 1/2 tsp smoked paprika, 1 tsp kosher salt, and 1/4 tsp black pepper.
Taste and adjust if needed. For more heat, add 1–2 more tablespoons hot sauce now; for a slightly milder bake, keep it as written and serve extra hot sauce at the table.
Step 5: Combine pasta, chicken, sauce, and some cheese
Add the drained pasta and the 3 cups shredded chicken to the pot with the sauce.
Stir until everything is evenly coated. Stir in 1 1/2 cups shredded cheddar (this melts into the sauce and makes the bake extra gooey).
Spoon the mixture into the prepared baking dish and spread into an even layer.
Step 6: Top with cheese and bake until bubbly
Sprinkle the remaining 1/2 cup cheddar and the 1 cup mozzarella evenly over the top. If using, sprinkle on the 1/3 cup blue cheese crumbles for extra tang.
Bake uncovered at 375°F (190°C) for 20 to 25 minutes, until the edges are bubbling and the cheese is fully melted.
If you want more browning on top, broil on high for 1 to 2 minutes—watch closely so it doesn’t scorch.
Step 7: Rest, garnish, and serve
Let the pasta bake rest for 5 minutes so the sauce sets up slightly (it will still be creamy).
Finish with sliced scallions and drizzle with 1 to 2 tbsp hot sauce (or more, to taste). Serve hot.
Pro Tips
- Undercook the pasta: Stopping 2 minutes early prevents it from turning soft in the oven.
- Shred your own cheese if you can: Pre-shredded cheese can contain anti-caking agents that make sauces slightly grainy.
- Control the spice level: Start with 1/2 cup hot sauce, then add more at the end. You can always add heat, but you can’t take it away.
- Keep the chicken moist: If your shredded chicken is very lean/dry, stir in 2 tbsp more ranch dressing or 2 tbsp milk before baking.
- Blue cheese tip: If you love blue cheese, stir half into the sauce and sprinkle the rest on top for the best flavor.
Variations
- Extra-crunchy topping: Add 1/2 cup panko breadcrumbs tossed with 1 tbsp melted butter over the cheese before baking.
- Buffalo chicken mac bake: Swap penne for 12 oz elbow macaroni and bake as directed.
- Veggie boost: Stir in 2 cups chopped steamed broccoli or 1 cup finely diced celery with the pasta for classic Buffalo vibes.
Storage & Make-Ahead
Refrigerate: Cool leftovers, cover, and refrigerate for up to 4 days. Reheat in a 350°F (175°C) oven for 15–20 minutes (covered with foil), or microwave individual portions until hot.
Make-ahead: Assemble the casserole (through topping with cheese), cover tightly, and refrigerate up to 24 hours. Bake at 375°F (190°C) for 30 to 35 minutes (it takes longer when cold), then rest 5 minutes and garnish.
Freeze: Wrap tightly and freeze up to 2 months. Thaw overnight in the fridge before baking, or bake from frozen covered at 350°F (175°C) for 60 minutes, then uncover and bake 10–15 minutes more until bubbly.
