My Review of Costco’s Pork Tenderloins with Garlic Rosemary

Costco has added a new pre-marinated meat to its prepared foods section, and it’s perfect for busy weeknights or summer grilling: Garlic Rosemary Pork Tenderloins. If you’re looking for something that’s quick to cook but still packed with flavor, this one is definitely worth trying.

The tenderloins come raw but fully pre-marinated, so there’s no prep work needed. The pork is sliced and seasoned with a flavorful blend of garlic and rosemary.

What I love most about it is the convenience. You can just throw it on the grill, sear it in a pan, or broil it in the oven—whatever works for you. It cooks up quickly, and the marinade gives the pork a really nice depth of flavor without being overpowering. It’s perfect when I’m feeling lazy to spend a lot of time cooking in the kitchen.

At $4.49 per pound, it’s also a great value, especially for pork tenderloin, which is naturally lean and tender. At $16-$18 a pack, it’s a budget-friendly way to add variety to our meals without having to plan ahead to marinate.

We’ve already had it a few times. For a family dinner, I grilled the pork and served it with Costco’s Mac and Cheese (which the kids love) and Costco’s Broccoli and Walnut Salad (my husband and I are big fans). The whole meal came together quickly and felt totally effortless.

I also had it the next day for lunch as leftovers and ate it with Costco’s grain and celery salad. The pork held up really well. I’m always looking for versatile, ready-to-cook proteins, and this one checks all the boxes.

If you’re looking for something easy, affordable, and delicious, definitely keep an eye out for the Garlic Rosemary Pork Tenderloins at Costco. 

It’s a smart shortcut for a homemade meal that doesn’t taste like a shortcut—and perfect for summer dinners when you want to keep things simple and easy.
