Ingredients
For the Ranch Cream Sauce
- 2 tablespoons unsalted butter
- 1 clove garlic, minced
- 2 tablespoons all-purpose flour
- 1 cup heavy cream
- 1 /4 cup chipotle lime ranch dressing (or any flavor)
- Salt and pepper to taste
For the Casserole
- 2 cups cooked and shredded chicken
- 8 ounces small shells pasta
- 1 cup mozzarella cheese, shredded
- 1 cup cheddar cheese, shredded
- 3 slices bacon, cooked and chopped
- Fresh parsley for garnish
For the Pan
- 1 tablespoon butter
- 1 clove garlic
Instructions
Preparation
- 1 Preheat your oven to 350°F (175°C). This moderate temperature ensures even heating without burning the cheese on top.
- 2 Cook the pasta according to package directions until al dente. Small shells work perfectly because they capture the creamy sauce in their curves, but you can substitute with penne or rotini if needed.
Make the Ranch Cream Sauce
- 3 Heat a small pot over medium heat and add 2 tablespoons butter. Once melted, whisk in the minced garlic and cook for about 30 seconds until fragrant. The garlic should sizzle gently – if it’s browning too quickly, reduce the heat.
- 4 Whisk in the 2 tablespoons flour and continue whisking for 30-60 seconds to cook out the raw flour taste. This creates a roux that will thicken your sauce beautifully.
- 5 While continuing to whisk constantly, slowly pour in the 1 cup heavy cream. This gradual addition prevents lumps from forming and ensures a silky smooth sauce.
- 6 Add the 1/4 cup ranch dressing and season with about 1/2 teaspoon salt and pepper to taste. The ranch adds both flavor and helps stabilize the sauce.
- 7 Cook until the sauce begins to simmer and thicken, about 2-5 minutes. You’ll know it’s ready when it coats the back of a spoon. If it’s not thickening, increase the heat slightly, but avoid boiling which can cause the sauce to break.
- 8 Remove the sauce from heat once thickened and set aside.
Assemble the Casserole
- 9 Drain the cooked pasta thoroughly – excess water will dilute your creamy sauce.
- 10 In a small bowl, mix together the 1 cup mozzarella and 1 cup cheddar cheese. This blend gives you the perfect combination of stretch and sharp flavor.
- 11 Prepare your 9×13 inch casserole dish by rubbing the 1 tablespoon butter and 1 clove garlic all over the bottom and sides. This prevents sticking and adds an extra layer of flavor.
- 12 Layer half the pasta in the prepared dish, then top with half the 2 cups shredded chicken. Sprinkle lightly with salt and pepper to season each layer.
- 13 Pour half the ranch cream sauce over this layer, then sprinkle with half the cheese mixture.
- 14 Repeat with the remaining pasta, chicken, sauce, and cheese. Top everything with the chopped bacon for that final flavor punch.
Bake and Finish
- 15 Bake for 20 minutes or until the casserole is heated through and the cheese is melted and bubbly around the edges. The top should be golden brown in spots.
- 16 Remove from the oven and let rest for 5 minutes before serving. Sprinkle with fresh parsley for a pop of color and freshness.
Recommended Equipment and Kitchen Tools
Essential Tools (for best results)
- Large pot for cooking pasta – A 4-quart capacity ensures pasta cooks evenly without overcrowding
- Medium saucepan for the ranch cream sauce – Heavy-bottomed pans prevent scorching and ensure even heat distribution

- 9×13 inch casserole dish – Glass or ceramic dishes provide even heat distribution and attractive presentation
Helpful Upgrades
- Kitchen scale for precise measurements – Especially helpful for consistent results when doubling the recipe
- Microplane grater for fresh garlic – Creates a finer mince that distributes more evenly than knife-chopped
- Silicone spatula for sauce stirring – Won’t scratch your cookware and gets into pan corners better than wooden spoons
- Instant-read thermometer – Ensures your sauce reaches the proper temperature without overheating
Nice-to-Have Options
- Stand mixer with paddle attachment – Makes quick work of shredding rotisserie chicken if you’re starting with whole chicken
- Food processor – Perfect for quickly chopping bacon or grating large amounts of cheese
- Aluminum foil – Useful for covering the casserole if the top browns too quickly during baking

Perfect Pairing Suggestions
Beverage Pairings
A crisp Sauvignon Blanc or Pinot Grigio cuts through the richness beautifully, while beer lovers should reach for a wheat beer or light lager that won’t compete with the creamy flavors.

Pro Tips and Troubleshooting
Professional Techniques
Cook pasta 1 minute less than package directions since it continues cooking in the oven. Salt your pasta water generously – it should taste like seawater for properly seasoned pasta. Room temperature ingredients blend more easily, so remove cream and eggs from refrigerator 30 minutes before cooking. Layer flavors by seasoning each component separately rather than relying solely on the ranch for flavor.
Common Mistake Prevention
Never boil the cream sauce – it will break and become grainy. If your sauce seems thin, simmer uncovered for 2-3 additional minutes rather than adding more flour. Drain pasta thoroughly and even toss with a little oil to prevent sticking. Don’t skip the garlic butter in the pan – it prevents sticking and adds crucial flavor.
Storage and Reheating
Refrigerate leftovers for up to 4 days in covered containers. Reheat individual portions in the microwave at 50% power for 2-3 minutes, stirring halfway through. For oven reheating, cover with foil and bake at 325°F for 15-20 minutes. Freezes well for up to 3 months – thaw overnight before reheating.
Make-Ahead Strategies
Assemble the entire casserole up to 24 hours ahead and refrigerate covered. Add 10 minutes to baking time if starting from cold. Cook components separately and store – pasta, sauce, and proteins can be prepped 2 days ahead and assembled when ready to bake.
This casserole proves that sometimes the best recipes are the ones that bring everyone together around the table, creating those perfect moments where good food and great company intersect in the most delicious way possible.
