How to Cook Costco Chicken Patties

Kirkland Signature Lightly Breaded Chicken Breast Fillets are frozen, fully cooked chicken patties sold at Costco warehouses.

They come in a 3-pound bag with individually portioned boneless skinless chicken breast pieces coated in a light panko-style breading.

Many shoppers compare them to Chick-fil-A sandwiches. The fillets work for quick weeknight dinners, meal prep, chicken sandwiches, salads, and chicken parmesan dishes.

This guide covers 4 cooking methods: air fryer, conventional oven, stovetop, and microwave. Cooking time ranges from 3 minutes (microwave) to 20 minutes (oven).

You will need a baking sheet, air fryer basket, skillet, or microwave-safe plate depending on your method. A food thermometer helps confirm doneness.

Cooking Methods Comparison

Recommended Method: Air fryer produces the crispiest coating and juicy interior in under 20 minutes.

Method 1: Air Fryer (Recommended)

The air fryer method takes 18-20 minutes at 375F and produces restaurant-quality crispy chicken patties. Hot circulating air crisps the breading without added oil. Best for 2-4 servings at a time.

Step 1: How Do You Prepare the Chicken Patties?

No prep needed. Cook directly from frozen without thawing.

Instructions:

1. Remove frozen patties from the bag
2. Do not defrost or add cooking spray

Equipment: Air fryer (Ninja Foodi, Philips, Cosori, or similar), tongs

Step 2: What Temperature and Time Do You Use?

Heat your air fryer to 375F. Place frozen fillets in a single layer in the basket with space between each piece for air circulation.

Instructions:

1. Preheat air fryer to 375F
2. Arrange patties in single layer, no overlapping
3. Cook for 18-20 minutes total

Temperature: 375F

Time: 18-20 minutes

Step 3: When Do You Flip the Patties?

Flip the chicken patties at the 12-minute mark. Then flip again during the last 2 minutes for even browning on all sides.

Instructions:

1. Flip patties after 12 minutes
2. Flip once more at 18 minutes for final crisping

Checkpoint: At 12-minute mark, patties should be golden on bottom

Step 4: How Do You Know When They’re Done?

The breaded chicken patties are done when golden brown all over with a crispy exterior. Since these are pre-cooked, you are mainly reheating them.

Instructions:

1. Check that the coating is golden brown and crispy
2. Insert meat thermometer into thickest part
3. Let rest 1-2 minutes before serving

Target Temperature: 165F internal temperature

Visual Indicator: Golden brown coating, steaming when cut open

Method 2: Conventional Oven

Baking in a conventional oven takes 15-20 minutes at 400F. This method works well for cooking multiple chicken patties at once for family meals or meal prep.

Step 1: How Do You Prepare for Oven Cooking?

Line a baking sheet with foil for easy cleanup. No oil needed.

Instructions:

1. Preheat oven to 400F
2. Line baking sheet with aluminum foil
3. Place frozen fillets on sheet in single layer

Equipment: Baking sheet, aluminum foil, oven mitts

Step 2: What Temperature and Time Do You Use?

Bake at 400F for 15-20 minutes. Some ovens run hot, so check at 13-14 minutes to prevent the bottom from burning.

Instructions:

1. Place baking sheet on middle rack
2. Bake for 15-20 minutes until heated through

Temperature: 400F

Time: 15-20 minutes

Step 3: Do You Need to Flip?

Flipping is optional but helps with even browning. If you want extra crispiness on both sides, flip halfway through cooking.

Instructions:

1. Optional: flip at 8-10 minute mark
2. Continue baking until golden

Checkpoint: Check at 10 minutes for browning progress

Step 4: How Do You Know When They’re Done?

Patties are done when the breading is golden brown and the internal temperature reaches 165F.

Instructions:

1. Check internal temperature with food thermometer
2. Look for golden brown coating
3. Let rest 2 minutes before serving

Target Temperature: 165F

Visual Indicator: Golden brown edges, slight steam when cut

Method 3: Stovetop / Skillet

Pan-frying frozen chicken patties takes 10-14 minutes over medium heat. This method gives you good control over browning and works great for quick single servings.

Step 1: How Do You Prepare the Skillet?

Add a thin layer of vegetable oil (about 1/8 inch) to a non-stick skillet or cast iron pan.

Instructions:

1. Add oil to coat bottom of skillet
2. Heat over medium heat until oil shimmers

Equipment: Non-stick skillet or cast iron pan, spatula, vegetable oil

Step 2: What Heat Level and Time Do You Use?

Cook over medium heat for 5-7 minutes per side. Medium heat prevents the breading from burning before the patty heats through.

Instructions:

1. Place frozen patties in hot oil
2. Do not overcrowd the pan
3. Cook 5-7 minutes on first side

Heat Level: Medium (setting 5 out of 10)

Time: 10-14 minutes total (5-7 per side)

Step 3: When Do You Flip?

Flip after 5-7 minutes when the bottom is golden brown. Only flip once to keep the breading intact.

Instructions:

1. Check bottom for golden color at 5 minutes
2. Flip when golden brown
3. Cook another 5-7 minutes

Checkpoint: At 5-minute mark, lift edge to check color

Step 4: How Do You Know When They’re Done?

Both sides should be golden brown. Internal temperature should reach 165F.

Instructions:

1. Both sides golden brown
2. Check internal temperature
3. Drain on paper towel briefly

Target Temperature: 165F

Visual Indicator: Golden brown on both sides, crispy coating

Method 4: Microwave

Microwaving takes only 3 minutes but produces a softer, less crispy result. Use this method when speed matters more than texture.

Step 1: How Do You Prepare for Microwave Cooking?

Place frozen patties on a microwave-safe plate. Do not stack them.

Instructions:

1. Place frozen fillets on microwave-safe plate
2. Arrange in single layer

Equipment: Microwave-safe plate

Step 2: What Power Level and Time Do You Use?

Microwave on HIGH power for 3 minutes. Rotate the plate halfway through for even heating.

Instructions:

1. Microwave uncovered on HIGH for 3 minutes
2. Rotate plate 1/2 turn at 1.5 minutes

Power Level: HIGH (100% power)

Time: 3 minutes

Step 3: Do You Need to Rotate?

Yes. Rotate the plate halfway through to prevent cold spots.

Instructions:

1. Pause at 1.5 minutes
2. Rotate plate 180 degrees
3. Continue cooking

Checkpoint: At 1.5-minute mark

Step 4: How Do You Know When They’re Done?

Let stand 1 minute after microwaving. The patty should be steaming and reach 165F internal temperature.

Instructions:

1. Let stand 1 minute before serving
2. Check that patty is steaming throughout
3. Verify internal temperature if unsure

Target Temperature: 165F

Visual Indicator: Steam rising, hot throughout

Troubleshooting Common Issues

Issue: Breading is soggy, not crispy

Cause: Using microwave or overcrowding air fryer basket

Solution: Switch to air fryer or oven method. Arrange patties in single layer with space between each piece for air circulation.

Issue: Patties are burnt on outside, cold inside

Cause: Temperature too high or patties stacked

Solution: Lower temperature by 25F. Cook in single layer only. Do not rush the cooking process.

Issue: Uneven browning

Cause: Not flipping during cooking

Solution: Flip halfway through cooking time. In air fryer, shake basket or flip at 12-minute mark.

Issue: Dry interior

Cause: Overcooked or cooked too long after thawing

Solution: Cook from frozen only. Reduce cooking time by 2-3 minutes and check internal temperature.
