If you’re trying to lose weight but don’t have the energy to cook, Costco’s premade meals can be a lifesaver—if you know which ones to grab. Fitness coach Trent Harrison shares his top picks for high-protein, low-calorie meals that make staying on track simple and tasty.

“I just don’t want to cook tonight, so I’m gonna grab an Ultimate Chicken BLT salad,” Harrison joked. “No, you’re not. There are way better options at Costco that are premade besides the salad.”

Here are the top options he recommends for anyone on a weight loss journey:

1. Hot Smoked Norwegian Salmon

Harrison highlights Costco’s smoked salmon as a quick, protein-packed option. “This comes in three flavors—pepper, traditional, and maple. It’s very easy to prepare and perfect for a salmon salad or even over rice,” he says. Salmon is not only rich in protein, but it’s also loaded with heart-healthy omega-3 fatty acids, which support brain health and reduce inflammation.

2. Chicken Cacciatore

For a cozy, home-style meal, Harrison recommends chicken cacciatore. “This one has a tomato sauce with it, so all you need to do is serve it with a side of vegetables. Super simple to make. It’s 22 grams of protein for just 150 calories. Perfect for those cold nights, and it’s packed full of flavor,” he explains. Tomatoes are also rich in antioxidants, making this meal both satisfying and nutritious.

3. Pot Roast

If you’re craving a traditional meal without the hassle, Harrison points to Costco’s premade pot roast. “This has 26 grams of protein for 230 calories and is perfect paired with potatoes on a cold winter night,” he says. Beef provides iron and B vitamins, while the high protein content helps with muscle repair and satiety—keeping you full longer.

Bonus side: Roasted Brussels Sprouts

No protein without vegetables! Harrison suggests pairing your protein with Costco’s chef-hacked roasted Brussels sprouts. “All you gotta do is pop this in the air fryer to get crispy Brussels sprouts. Pair this with your favorite protein for an easy meal,” he says. Brussels sprouts are packed with fiber and vitamins C and K, making them an excellent side for overall health.

“These meals are easy, high in protein, and perfectly portioned to support weight loss,” Harrison adds. 

Whether you’re meal-prepping or just looking for a no-fuss dinner, these Costco options make it easy to stay on track without sacrificing flavor—or your health.
