This guide will walk you through everything you need to know about this well-priced staple, including its nutrition, taste, cost, versatility, and suitability for a variety of dietary needs.
What Are Kirkland Signature Liquid Egg Whites?
Kirkland Signature Liquid Egg Whites are packaged, pasteurized egg whites sourced from cage-free eggs. They are sold in six-count cartons (each containing 16 ounces), making them easy to store and pour. Marketed as a low-fat, high-protein choice with no cholesterol, these egg whites are ideal for those targeting nutrition without fuss or excess calories.
Where to Find Kirkland Signature Egg Whites at Costco
You’ll typically locate the product in the refrigerated dairy section at Costco, close to the milk, butter, and other chilled essentials. Each six-pack offers significant savings compared to other retail options, making it a value choice for families, meal preppers, athletes, or anyone on a high-protein diet.

How Much Protein and How Many Eggs Per Carton?
When you buy the Kirkland pack, you’re getting a substantial supply. Here’s how it breaks down:
- One 16 oz carton = white from 15 eggs
- One serving (3 tbsp) = white from 1 egg
- 6-pack carton = the equivalent of 60 egg whites
| Package Size | Egg White Equivalent | Total Protein |
|---|---|---|
| Single carton (16 oz) | 15 eggs | 75g |
| 6-pack | 90 eggs | 450g |
Taste Test: How Do Kirkland Egg Whites Compare?
Let’s address one of the most common questions: Do liquid egg whites taste as good as fresh, whole eggs? While Kirkland Signature Egg Whites don’t match the richness of whole eggs (especially due to the absence of the creamy yolk), they have an appealingly mild flavor and blend seamlessly into many dishes. Most users report that the egg whites are neutral in taste—neither strongly eggy nor bland when properly seasoned or cooked with other flavorful ingredients.
Texture-wise, once cooked, they turn from a clear liquid to the familiar white, fluffy egg white you’d expect in omelets or scrambles. If you want to boost the experience, try adding spices, cheeses, or vegetables to enhance the meal’s taste and color.
Convenience & Versatility: Why Busy Cooks Love Them
One of the greatest strengths of Kirkland Signature Liquid Egg Whites is their convenience:
- No need to crack, separate, or waste egg yolks.
- Reduce prep and clean-up time—just open the carton and pour.
- Perfect for batch cooking and meal prepping.
- Stays fresh when refrigerated and unopened (check the carton for use-by dates).
- Easy to measure for recipes by volume, enhancing recipe precision.
Because they are pasteurized, Kirkland egg whites are safe for use in cold or uncooked applications, opening up a range of possibilities beyond breakfast (more on this below).
Is It Safe to Drink Costco Liquid Egg Whites?
Absolutely, and it’s a favorite among athletes and fitness enthusiasts! The Kirkland Signature Liquid Egg Whites are fully pasteurized, eliminating the risk of harmful bacteria such as salmonella. Thanks to this process—similar to how dairy milk is pasteurized—you can safely use them in shakes, smoothies, and other raw recipes.
Some packaging even includes a smoothie recipe for inspiration. If you’re increasing your intake of raw egg whites, bear in mind that high consumption may necessitate supplementing certain vitamins (like biotin), as raw egg whites can bind to biotin and prevent its optimal absorption. This is generally only a concern if you drink large quantities frequently.
Cooking and Baking with Kirkland Egg Whites: Dos and Don’ts
- Great for omelets, scrambled eggs, stir-fries, quiches, frittatas, and even in casseroles.
- Perfect addition to smoothies—boosting protein without altering flavor.
- Ideal for most baking recipes that call for egg whites only (e.g., some cakes, muffins, pancakes, waffles).
- Not recommended for whipping applications such as meringues or angel food cakes. The pasteurization process stabilizes the egg whites, so they won’t achieve the volume or firmness needed for foamy desserts.
- Works in most cooked dishes but not for recipes requiring raw or whipped foam structure.
The Value: Cost Breakdown & Comparison
| Store | Package Size | Total Cost | Cost per Pound |
|---|---|---|---|
| Costco | 6 x 16 oz cartons | $9.49 | $1.58 |
| Walmart | 2 lb carton | $3.87 | $1.93 |
Buying the Kirkland pack ensures an 18% savings compared to leading grocery competitors. For regular protein consumers, these savings quickly add up while providing a larger, fresher supply than single-egg alternatives.
Are Kirkland Egg Whites Healthy?
There’s little question—these egg whites check nearly every box for those focused on health:
- No cholesterol: Great for maintaining healthy blood cholesterol levels.
- Fat-free and carb-free.
- Only 25 calories per serving, all of which come from clean protein.
- Source of high-quality, bioavailable protein for muscle recovery and maintenance.
- Suitable for keto, paleo, vegetarian, low-carb, and heart-healthy diets.
While they are not labeled organic (because they’re cage-free, not free-range or organic eggs), they remain a popular pick for clean eaters and budget-conscious shoppers alike.
Practical Uses: Delicious Ways to Incorporate Egg Whites
- Egg white omelets with vegetables, herbs, and cheese
- Protein pancakes or waffles (swap in liquid egg whites for whole eggs or in addition to protein powder)
- Scrambles for breakfast burritos or bento boxes
- Stirred into oatmeal or overnight oats for a protein boost
- Mixed into smoothies for a creamy texture and extra protein
- Use in homemade protein bars or muffins
Because the egg whites are clear (no color additives) and take on a neutral palette, they meld well into savory or sweet dishes.
Expert Tips for Cooking with Liquid Egg Whites
- Season egg whites well (with salt, pepper, herbs, or spices) as their natural flavor is mellow.
- If you want a richer taste, combine a small amount of yolk or cheese.
- For fluffier omelets, cook over low to medium heat and avoid over-stirring.
- Stored unopened in the fridge, the product lasts several weeks; once opened, use within 5–7 days.
Potential Cons: Limitations to Consider
- Flavor and Texture: Some find the taste blander than whole eggs—especially when cooked alone with little seasoning.
- Not for Whipping: Due to pasteurization, they don’t whip well and are unsuitable for fluffy desserts requiring whipped egg whites.
- No yolk nutrients: Without yolks, you miss out on fat-soluble vitamins like A, D, E, K, and choline present in whole eggs.
- Not organic: These are cage-free but not certified organic or free-range.
