How to Make Cheesy Bacon Chicken & Potato Casserole
1. Preheat the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a 9×13-inch baking dish.
2. Prepare the Potatoes
Place the cubed potatoes in a large bowl.
Add:
- Olive oil
- Garlic powder
- Smoked paprika
- Salt
- Black pepper
Toss until evenly coated.
3. Give the Potatoes a Head Start
Spread the potatoes in the prepared baking dish.
Bake for approximately 20 minutes.
This head start helps make sure the potatoes become tender without overcooking the chicken later.
4. Prepare the Chicken
While the potatoes bake, place the chicken pieces in a bowl.
Add:
- Olive oil
- Garlic powder
- Onion powder
- Smoked paprika
- Italian seasoning
- Salt
- Black pepper
Toss well.
5. Cook the Bacon
If you have not already done so, cook the bacon until crisp.
Transfer to paper towels.
Once cool enough to handle, crumble it into small pieces.
6. Make the Sauce
Place a large saucepan over medium heat.
Add the butter.
7. Add the Garlic
Once the butter melts, stir in the minced garlic.
Cook for approximately 30–60 seconds, just until fragrant.
8. Add the Flour
Sprinkle in the flour.
Whisk continuously for approximately 1–2 minutes.
9. Add the Chicken Broth
Slowly pour in the chicken broth while whisking.
Continue whisking until smooth.
10. Add the Milk
Gradually pour in the milk.
Whisk until combined.
11. Add the Seasonings
Stir in:
- Dijon mustard
- Italian seasoning
- Garlic powder
- Onion powder
- Black pepper
12. Simmer
Cook over medium-low heat for approximately 4–5 minutes, stirring frequently.
The sauce should begin to thicken.
13. Add the Sour Cream
Reduce the heat to low.
Stir in the sour cream until smooth.
14. Add Cheddar
Add 1 cup shredded cheddar gradually.
Stir until melted.
Avoid aggressively boiling the sauce once the cheese has been added.
15. Remove the Potatoes
After their 20-minute head start, remove the baking dish from the oven.
The potatoes should be beginning to soften but not fully cooked.
16. Add the Chicken
Arrange the seasoned chicken pieces evenly over the potatoes.
17. Add Half the Bacon
Sprinkle approximately half of the crumbled bacon over the chicken and potatoes.
18. Pour Over the Sauce
Pour the creamy cheese sauce evenly over the casserole.
Use a spoon to help the sauce settle between the potatoes and chicken.
19. Cover
Cover the baking dish tightly with foil.
20. Bake
Return the casserole to the oven.
Bake covered for approximately 20 minutes.
21. Check the Potatoes
Carefully remove the foil.
Test a potato with a fork.
It should be nearly tender.
22. Check the Chicken
The chicken should be nearly or fully cooked.
Chicken must reach 165°F (74°C) in the thickest pieces.
23. Add the Cheese Topping
Sprinkle over:
- Cheddar
- Mozzarella
- Parmesan
24. Add Remaining Bacon
Sprinkle the rest of the bacon over the cheese.
25. Bake Uncovered
Return to the oven.
Bake for another 10–15 minutes.
The cheese should melt completely and the sauce should bubble around the edges.
26. Broil for Extra Browning
For a golden top, broil for approximately 1–2 minutes.
Watch carefully.
27. Rest
Remove from the oven.
Let the casserole rest for approximately 5–10 minutes.
This helps the sauce settle.

- Green onions
- Fresh parsley

Frequently Asked Questions
Can I use chicken thighs?
Yes.
Boneless, skinless chicken thighs work very well and stay especially juicy.
Cook to 165°F (74°C).
What potatoes work best?
Yukon Gold potatoes are excellent because they stay creamy while holding their shape.
Russets also work.
Can I use frozen potatoes?
Yes.
Frozen diced potatoes or hash brown cubes can work, but cooking time may differ.
Can I make this ahead?
Yes.
You can prepare the sauce, bacon, chicken, and potatoes ahead.
For best texture, assemble and bake close to serving time.
Why are my potatoes still hard?
They may have been cut too large or did not receive enough of a head start.
Cut them into roughly ¾-inch cubes and bake them before adding the chicken.

If using fully cooked chicken, add it later in the baking process so it does not dry out.
Can I add ranch?
