Ingredients
- Potatoes: 2.5 pounds Yukon Gold potatoes, scrubbed and chopped into 1-inch pieces
- Oil: 2 tablespoons olive oil
- Ranch Seasoning: 1 packet (1-ounce) dry ranch salad dressing mix (divided)
- Bacon: 8 slices thick-cut bacon, cooked and crumbled
- Aromatics: 1/2 cup finely chopped yellow onion
- Thickener: 3 tablespoons all-purpose flour
- Dairy: 1.5 cups whole milk
- Acid: 1 tablespoon lemon juice or white wine vinegar
- Protein: 2 pounds skinless, boneless chicken thighs, cut into bite-sized pieces
- Cheese: 1 cup shredded Cheddar cheese (divided into two 1/2-cup portions)
- Garnish: 1/4 cup freshly chopped green onions
Step-by-Step Instructions
1. Prep and Roast the Potatoes
- Preheat your oven to 425°F (220°C) and generously grease a 9×13-inch baking dish.
- Place the cubed Yukon Gold potatoes directly into the prepared baking dish.
- Drizzle the potatoes with olive oil and sprinkle with 1 tablespoon of the dry ranch dressing mix. Toss thoroughly until the potatoes are evenly coated.
- Roast uncovered for about 30 minutes, stirring halfway through, until the potatoes are fork-tender and light golden brown.
2. Cook the Bacon and Prepare the Sauce Base
- While the potatoes roast, heat a 12-inch skillet over medium heat and cook the bacon slices until crisp (about 10 minutes).
- Transfer the cooked bacon to paper towels to drain, then crumble once cool.
- Carefully drain the skillet, leaving behind about 3 tablespoons of the rendered bacon grease.
- Add the chopped onions to the bacon grease and sauté over medium heat for about 5 minutes until soft and translucent.
- Whisk in the all-purpose flour, cooking and stirring continuously for 1 minute to cook out the raw flour taste.
- Slowly pour in the whole milk while whisking constantly to prevent lumps. Simmer until the mixture thickens and begins to bubble.
- Remove the skillet from the heat and stir in the lemon juice (or white wine vinegar) along with the remaining ranch dressing mix.
3. Assemble and Bake the Casserole
- Remove the baking dish with the roasted potatoes from the oven.
- Evenly scatter the raw bite-sized chicken thigh pieces over the top of the roasted potatoes.
- Layer the crumbled bacon evenly across the chicken.
- Sprinkle the first 1/2 cup of shredded Cheddar cheese over the bacon layer.
- Pour the prepared creamy ranch sauce uniformly across the entire dish.
- Return the baking dish to the 425°F (220°C) oven and bake for 15 minutes, or until the chicken pieces are cooked through and no longer pink.
4. Melt the Final Cheese Layer
- Carefully remove the casserole from the oven and sprinkle the remaining 1/2 cup of shredded Cheddar cheese evenly over the top.
- Return to the oven for an additional 5 minutes until the cheese is completely melted, bubbly, and lightly golden.
- Let the bake rest for a few minutes before garnishing with fresh green onions and serving warm.
Essential Cooking Tips
Potato Choices
Yukon Golds are ideal because they have a naturally buttery flavor and hold their shape well, but Russets or red potatoes can be used as alternatives.
Even Cooking
Cut your chicken thighs and potatoes into uniform, bite-sized pieces to ensure they cook at an even rate.
Resting Time
Allow the casserole to sit for 5 to 10 minutes after baking; this helps the creamy ranch sauce thicken up slightly and makes serving much cleaner.
