Let’s be honest: the frozen food aisle at Costco can feel like a goldmine and a minefield at the same time. With towering stacks of pizzas, ready-to-heat pastas, international entrées, and comfort foods galore, it’s easy to be lured in by convenience and crowd-pleasing flavor. But behind the glossy packaging and bulk deals lie some nutritional hits—and plenty of misses. That’s where dietitians come in.
While some frozen meals offer balanced portions of lean proteins, fiber-rich veggies, and clean ingredients, others are loaded with sodium, added sugars, saturated fats, and chemical preservatives. And when you’re feeding a family or trying to stay on track with your health goals, those details matter more than ever. The good news? You don’t have to decode every nutrition label or memorize every unpronounceable additive to make smarter choices.
We’ve rounded up nine frozen Costco meals that dietitians actually recommend—meals that taste good and provide real nutritional value. From omega-3-rich salmon burgers to veggie-packed frittatas, these items strike the right balance of convenience and health. On the flip side, we’re also spotlighting nine popular frozen dinners they advise steering clear of—whether it’s due to sky-high sodium counts, excessive calories, or misleading “health halo” labels.
Whether you’re stocking your freezer for busy weeknights or just trying to make better choices on your next Costco haul, this guide will help you shop smarter. No guilt-trips, just honest feedback from nutrition experts on what’s worth tossing in your cart—and what’s better left on the shelf.

1. Marie Callender’s Chicken Pot Pie: Comfort Food Catastrophe
Golden brown crust might look tempting, but what lurks beneath should give health-conscious shoppers pause. A single pie packs a whopping 700+ calories and nearly a day’s worth of saturated fat.
Sodium levels soar to alarming heights, with one pie containing approximately 1,400mg—over half the daily recommended limit. The ingredient list stretches to uncomfortable lengths, featuring numerous preservatives and additives.
Nutritionists particularly warn about the trans fat content hiding in the flaky crust. While the occasional indulgence won’t derail health goals, making this a regular meal choice could contribute to heart disease risk and weight management challenges.
2. Kirkland Signature Chicken Bake: Calorie Bomb in Disguise
Mammoth in size and calorie content, this savory hand-held item masks its nutritional downfalls behind convenience. A single bake contains a staggering 1,050 calories—more than half a day’s worth for many adults.
The sodium content reaches nearly 2,000mg, potentially contributing to water retention and blood pressure concerns. Protein content is decent, but comes with an excessive fat payload that nutritionists find concerning.
Dietitians particularly note the misleading nature of chicken in the name, suggesting healthfulness while delivering a meal more calorie-dense than many fast food options. For those watching weight or heart health, this convenient option comes with too many nutritional compromises.
3. Bibigo Beef Bulgogi Mandu: Sugar-Loaded Dumplings
Authentic-looking Korean dumplings promise cultural flavors but deliver unexpected health pitfalls. Despite containing real beef and vegetables, these little pouches hide surprising amounts of added sugar in their seasoning.
Sodium levels exceed what dietitians consider reasonable, with just a few dumplings containing nearly a third of daily sodium recommendations. The wrapper dough contains refined flours that spike blood sugar without providing lasting energy.
Nutrition professionals note the frustrating combination of quality protein paired with problematic additives and sweeteners. While these might work as an occasional appetizer in small portions, they fail to deliver the clean nutrition profile typically expected from traditional Korean cuisine.
4. Pierre Signatures Angus Cheeseburgers: Heart Health Hazard
Convenience comes at a steep nutritional cost with these pre-cooked frozen burgers. Each patty delivers an alarming amount of saturated fat—nearly half the recommended daily limit in just one serving.
Sodium content reaches concerning levels, with preservatives and additives lengthening the ingredient list substantially. Nutritionists point out that despite the “Angus” label suggesting quality, the meat contains fillers and additives not found in fresh ground beef.
The cheese component adds additional processed ingredients rather than simple dairy. For those with cardiovascular concerns or cholesterol issues, dietitians recommend avoiding these entirely in favor of making fresh burgers from quality ground beef or plant-based alternatives.
5. Royal Asia Honey Walnut Shrimp: Sweet Seafood Sabotage
Masquerading as a restaurant favorite, this frozen version packs a sugary punch that nutrition experts find alarming. The sweet sauce coating contains more sugar than many desserts, turning potentially healthy seafood into a glucose-spiking concern.
Breading adds empty calories and refined carbohydrates while diluting the nutritional benefits of the shrimp. The oil used for pre-frying these morsels before freezing adds unnecessary fat to an otherwise lean protein source.
Dietitians note the irony of taking shrimp—naturally low in calories and high in protein—and transforming it into a dish with the nutritional profile of candy. Those seeking seafood’s health benefits would be better served by simpler preparation methods.
6. Don Miguel Chicken and Cheese Mini Tacos: Flavor Facade
Tiny in size but mighty in problematic ingredients, these mini tacos disappoint nutrition professionals across the board. The chicken filling contains more fillers and additives than actual meat, creating a textural oddity rather than authentic protein.
Oil-saturated shells become soggy when heated, never achieving the crisp texture expected from proper tacos. Salt levels soar while nutritional value plummets, with minimal fiber, vitamins, or minerals to justify their place in a balanced diet.
Dietitians particularly note the artificial flavor enhancers used to compensate for quality ingredients. For those seeking Mexican-inspired meals, nutritionists recommend building fresh tacos with simple ingredients rather than relying on these processed approximations.
7. Kirkland Signature Cheese Pizza: Doughy Disappointment
Enormous in size but underwhelming in quality, this pizza relies on quantity over nutritional merit. The thick, doughy crust dominates each slice, creating a carbohydrate overload without the fiber benefits of whole grains.
Cheese coverage appears generous but uses lower-quality dairy that lacks the flavor complexity of authentic mozzarella. Sauce contains added sugars that nutritionists find unnecessary and potentially problematic for those watching glucose levels.
Dietitians point out that despite its massive size, this pizza lacks vegetable toppings that could add nutritional value. The excessive portion size encourages overeating, with many consumers underestimating how many calories they’re consuming when having “just a couple slices.”
8. Kirkland Signature Chicken Pot Pie: Sodium Overload
Massive portion size creates the first red flag for this comfort food classic. Each pie serves as a meal for two but is often consumed by individuals, leading to significant calorie overconsumption.
The flaky crust, while texturally pleasing, contains trans fats and refined flours that nutrition experts consistently warn against. Inside, the creamy filling relies heavily on sodium-laden flavor enhancers rather than quality herbs and spices.
Vegetables appear in minimal quantities, overwhelmed by gravy and crust. Dietitians note that while homemade pot pies can be reasonably nutritious when properly portioned with more vegetables than crust, this commercial version misses the mark on both ingredient quality and proportions.
9. Kirkland Signature Frozen Pizza: Processed Cheese Problem
Mammoth-sized and marketed for value, this pizza prioritizes quantity over quality in concerning ways. The cheese blend contains oils and fillers that create a rubbery texture rather than the authentic melt expected from real dairy.
Toppings appear generous but contain processed meats high in nitrates and preservatives that nutrition experts consistently flag as problematic. The sauce lacks the fresh tomato flavor of quality pizzas, relying instead on sugar and salt for taste.
Dietitians particularly note the excessive grease that pools on top when heated, indicating low-quality ingredients and unnecessary added fats. For pizza lovers, nutrition professionals recommend either making homemade versions or choosing brands with cleaner ingredient profiles.
