The last time that I was at Costco I bought the fully cooked Kirkland Oven Browned Turkey Breast and am really pleased with the purchase. We were in the mood for something other than chicken and were looking for some form of lean protein that I could use for fast and easy dinners.
Stick with me and we will cover the best way to cook this turkey breast as well as the proper way to slice!

This breast costs $4.59 per pound and comes in different sizes. The one I bought weighed 2.37 pounds and cost $10.88.
Oven Browned Turkey Breast Cooking Instructions
The Kirkland Oven Browned Turkey Breast is fully cooked and ready to eat. However, if you want to heat the turkey up to eat it warm then the instructions are pretty easy!
- Preheat your oven to 350F.
- Remove the turkey breast from the plastic wrap.
- Place the turkey breast in a shallow pan and add 1/2 cup of water.
- Cover the pan with aluminum foil.
- Place in the oven and bake for 1 hour or until the internal temperature reaches 140F.
- Remove from oven, let cool for 10 minutes and serve.
Tips to Add More Flavor
If you want to make the turkey more flavorful then here are some suggestions:
Use a More Flavorful Liquids
Instead of adding water to the pan you could substitute chicken or turkey broth to boost the savory, umami flavor. You could also use apple juice to add a nice sweetness.
Add Aromatic Vegetables or Sweet Fruits
If you have room in the pan then consider tossing in some onion wedges, smashed garlic cloves or some rough chopped carrots and celery. The garlic and onions will add a savory base while the carrots and celery will add sweetness and depth.
Turkey and fruit make a wonderful combination so consider adding some apple slices, orange slices or even a handful of cranberries!
Use Herbs and Seasonings
Go ahead and add some of these herbs and seasonings directly to the turkey. Wet the surface of the turkey to help the seasonings adhere.
Fresh rosemary or thyme sprigs pair beautifully with turkey while. Sage leaves provide an earthy, holiday-like aroma. Bay leaves are subtle but aromatic.
Butter pats, dotted around the turkey, provide richness.
For seasonings you can never go wrong with salt and pepper but McCormick’s poultry seasoning is an absolute classic. For a pop of color consider sprinkling on a little smoked paprika!

How to Slice the Turkey
I was intrigued to see that the back of the packaging had slicing instructions.
Apparently you slice the meat Left to Right, the “short way”, when you want to make sandwiches and Top to Bottom, the “long way”, when you want to serve slices as an entrée.
Slicing in either direction is fine but you will get more tender meat if you slice it the “long way” as this will be cutting against the grain of the meat fibers.

Taste Test!
The roasted turkey breast is slightly salty but otherwise unseasoned. Overall this is a relatively bland piece of turkey so I really would suggest using some of the flavor boosting tips given above.
I have been using slices of the turkey as an easy protein to go with Mediterranean Salads. It is also pretty good when diced up and added to an omelet made with Kirkland egg whites.
The roast is a nice thing to have in the refrigerator for when I get the 3:00 p.m. hunger pains and I want a filling, low calorie snack. It’s easy to open the fridge, carve off a slice and get about my day.
Overall the turkey breast tastes exactly like it should.
