Whether you’ve got Hampton House chicken parmesan from Costco or another brand like Tyson breaded chicken that you’re turning into parmesan, I’ll walk you through exactly how long to cook your Costco chicken parmesan for crispy, cheesy perfection every time!
What Is Costco Chicken Parmesan?
Before diving into cooking times, let’s talk about what you’re actually working with. Costco sells several versions of chicken parmesan, with Hampton House being one of the most popular. Typically, you’ll get:
- Eight individually wrapped chicken cutlets per package
- Breaded chicken breast stuffed with tomato sauce and cheese
- A slice of parmesan cheese on the bottom for extra flavor
- Raw chicken that needs to be fully cooked (not pre-cooked)
Hampton House Chicken Parmesan from Costco comes with large white meat chicken breasts coated in a crispy seasoned breading with tomato sauce and cheese inside. Each breast is individually packaged for convenience. The typical cost is around $12.99 Canadian for eight pieces, making it an economical option for family meals.
Cooking Times for Costco Chicken Parmesan
The cooking time varies depending on which method you choose. Here’s a breakdown of the most popular cooking methods:
Oven Baking (Most Recommended Method)
The oven provides that perfect balance of crispy exterior and juicy interior. Here’s what you need to know:
- Cooking temperature: Preheat your oven to 375°F (190°C)
- Cooking time: 25-30 minutes for thawed chicken
- From frozen: Add approximately 5 minutes (30-35 minutes total)
- Internal temperature: Cook until internal temperature reaches 165°F (74°C)
- Extra crispiness tip: Broil for 2-3 minutes at the end
Step-by-step oven instructions:
- Preheat your oven to 375°F (190°C)
- Remove packaging and place chicken on a baking sheet lined with parchment paper
- Bake for 25-30 minutes (30-35 if frozen)
- Check internal temperature with a meat thermometer (should be 165°F)
- Optional: Broil for 2-3 minutes for extra crispy breading
- Let rest for 5 minutes before serving
Air Fryer Method (Fastest and Crispiest)
If you want super crispy chicken parmesan in less time, the air fryer is your best friend:
- Cooking temperature: Preheat air fryer to 350-370°F (175-188°C)
- Cooking time: 12-16 minutes total
- Technique: Flip halfway through cooking
- Internal temperature: Always check for 165°F (74°C)
- Rest time: 2 minutes before serving
One reviewer mentioned cooking these in their air fryer at 375°F for just 15 minutes with excellent results. The air fryer’s circulating hot air creates a perfectly crispy exterior while keeping the chicken juicy inside.
Microwave Method (Quickest Option)
When you’re in a rush and need dinner ASAP, the microwave works in a pinch:
- Cooking time: 4-6 minutes on high power
- Technique: Cover with microwave-safe lid, flip halfway through
- Rest time: 1-2 minutes before serving
- Note: Texture will be softer compared to oven/air fryer methods
The microwave is definitely the fastest option at just 4-6 minutes total cooking time, but you’ll sacrifice some of that crispy texture that makes chicken parmesan so satisfying.
Common Mistakes to Avoid
Don’t let these common errors ruin your Costco chicken parmesan:
- Not preheating your cooking appliance – This leads to uneven cooking and soggy breading
- Overcrowding the baking sheet or air fryer – Give each piece room for air to circulate
- Skipping the meat thermometer – Visual cues aren’t reliable; always check the temperature
- Cutting into the chicken immediately – Let it rest to keep juices from running out
- Forgetting to flip when microwaving – This leads to hot spots and cold centers
How to Tell When Costco Chicken Parmesan Is Done
Your chicken parmesan is perfectly cooked when:
- Internal temperature reaches 165°F (74°C)
- Breading is golden brown and crispy
- Cheese inside is fully melted and bubbly
- Meat is opaque white with no pink areas
- Juices run clear when cut
Tips for Enhancing Your Costco Chicken Parmesan
While Costco’s chicken parmesan is delicious on its own, here are some ways to take it to the next level:
- Add extra cheese: In the last 5 minutes of cooking, sprinkle additional mozzarella or freshly grated Parmesan on top
- Elevate with herbs: Add fresh basil or parsley just before serving
- Use a wire rack: When baking, place chicken on a wire rack over your baking sheet for better air circulation
- Don’t cover with foil: This traps steam and makes the breading soggy
- Sauce it up: Serve with extra warm marinara sauce on the side for dipping

How To Make Costco Chicken Parmesan
I prep for eight servings of food every night (so my husband can have leftovers the next day), but feel free to adjust the amounts as needed.
- 8 pieces Tyson Panko Breaded Chicken Breast Tenderloins
- 1 (28-ounce) jar Rao’s Homemade Marinara Sauce
- 1 (16 to 18-ounce) package spaghetti
- 8 slices mozzarella cheese (or shredded)
Preheat the oven to 450°F.
Place the chicken on a baking sheet and bake for 20 minutes. Flip and bake for an additional 7 minutes, or until the internal temperature has reached at least 165°F.
While the chicken is baking, boil a pot of water and cook the spaghetti according to package directions. To time this with the chicken being done, I usually start this about 10 minutes after I’ve started the chicken. Drain the noodles and coat them with a little olive oil if they get too sticky.
Once the chicken is done, turn on the broiler to high. Add marinara on top of the chicken by the spoonful. We like a lot of sauce at my house, so I usually go through almost the whole jar. Place a slice of mozzarella on top of each piece of chicken. You can use shredded cheese instead.
Place the chicken under the broiler and melt the cheese. Keep an eye on it! Divide the spaghetti between eight plates and, if desired, spoon more sauce over it. When the chicken is done, simply place it on top of the pasta and enjoy.
