Yukon Gold potatoes slice evenly and hold their shape. You can use mozzarella for extra stretch or a cheddar-mozzarella mix. Frozen peas work perfectly straight from the bag. Swap chicken breast for thighs if you prefer richer flavor. Whole milk makes the creamiest sauce.

Step-by-step instructions
These clear steps build a creamy, cheesy chicken bake with perfectly cooked layers every time.
Step 1: Prep the potatoes
Slice the potatoes into even thin rounds so they cook through evenly. Toss them with a little oil, salt, pepper, and chili flakes before arranging in the baking dish.
Step 2: Arrange the base
Layer the seasoned potato slices evenly across the bottom of a glass baking dish. Overlap them slightly so there are no large gaps.
Step 3: Cook the chicken
Heat oil in a large skillet over medium-high heat. Add the diced chicken and cook until it is no longer pink on the outside, about five minutes.
Step 4: Add the vegetables
Stir in the diced red bell pepper and frozen peas. Cook for another three minutes until the pepper softens slightly and the peas are heated through.
Step 5: Make the creamy sauce
Melt butter in a saucepan, whisk in the flour, and cook for one minute. Slowly pour in the milk while whisking until the sauce thickens and turns smooth.
Step 6: Season the sauce
Add salt, black pepper, and garlic powder to the white sauce. Taste and adjust the seasoning so the sauce is well balanced and flavorful.
Step 7: Assemble the bake
Spread the chicken, peppers, and peas over the potato layer. Pour the creamy sauce evenly across the top, then sprinkle the shredded cheese over everything.
Step 8: Bake until golden
Bake at 375°F for thirty-five to forty minutes until the cheese is bubbly and golden. Let it rest five minutes before scooping so the layers set.
