Best Healthy Snacks at Costco (Updated Dietitian-Approved Roundup)

If you love saving money and time, Costco is a dream for stocking up on snacks. The challenge is that “healthy” can be a moving target—especially when you’re trying to keep added sugar in check without feeling deprived.

As a dietitian writing for MonkVee, I look at snacks through a few lenses: added sugar content, fiber, protein, ingredient quality, and how realistic they are for busy, real-life schedules. This updated-style roundup highlights some of the best healthy snacks at Costco right now, plus how to adapt them if you’re cutting down on sugar or experimenting with natural sweeteners like monk fruit and stevia.

How to Choose a Healthy Costco Snack (In 10 Seconds)

Before we get into specific products, here’s a quick mental checklist you can use in the aisle:

• Added sugar: Aim for <5–7 g added sugar per serving for everyday snacks; lower is better if you’re watching blood sugar.


• Protein: Target at least 5–8 g for staying power; 10–20 g is ideal for a snack that actually satisfies.


• Fiber: ≥3 g per serving helps with fullness and blood sugar steadiness.


• Ingredients: Prefer short ingredient lists with recognizable foods (nuts, seeds, whole grains, legumes, fruits, dairy, eggs).


• Portion awareness: Bulk bags are cost-effective, but pre-portion into containers or bags at home if you tend to overgraze.

With that in mind, let’s walk through the categories where Costco really shines.

1. High-Protein, Low-Sugar Snacks

Protein-based snacks are excellent for stable energy, especially if you’re cutting back on sugary granola bars or candy. Costco usually has multiple options in each of these categories.

Greek Yogurt (Single-Serve Cups or Large Tubs)

Plain or lightly sweetened Greek yogurt is one of the most versatile snacks in the warehouse.

• What to look for: Plain or “zero sugar” varieties, or those with ≤7 g added sugar per serving. Protein is often 12–18 g per cup.


• Why it’s a win: High protein, naturally contains calcium and probiotics. You control sweetness by adding fruit or a small amount of low-sugar sweetener.


• Smart upgrade: Buy plain Greek yogurt and sweeten it yourself with berries plus a few drops of monk fruit or stevia-based sweetener instead of pre-sweetened cups.

Cottage Cheese Cups or Tubs

Cottage cheese has made a comeback for good reason.

• What to look for: Options with 12–15 g protein per 1/2 cup, minimal added sugar (plain is ideal), and moderate sodium.


• Why it’s a win: Very filling, pairs well with both savory (cherry tomatoes, cucumbers) and sweet (fruit, cinnamon, a bit of monk fruit sweetener).


• On-the-go tip: Pre-portion into small containers and top with frozen berries (they’ll thaw by snack time).

Hard-Boiled Eggs (Pre-Cooked Packs)

Many Costco locations carry ready-to-eat hard-boiled eggs.

• Nutrition snapshot: About 6 g protein per egg, plus choline and healthy fats.


• Why it’s a win: Zero added sugar, minimal prep, and very satiating.


• Serving idea: Pair 1–2 eggs with a piece of fruit or a small handful of nuts for a balanced snack.

Jerky and Meat Sticks

Costco typically stocks several brands of beef, turkey, or chicken jerky and meat sticks.

• What to look for: ≤3–4 g sugar per serving, moderate sodium, and no excessive additives. Many newer brands use simple seasonings.


• Why it’s a win: Shelf-stable, high protein, and extremely portable.


• Pairing tip: Combine with raw veggies, grapes, or an apple to add fiber and volume.

2. Nut and Seed Snacks (Healthy Fats + Crunch)

Nuts and seeds are nutrient-dense, but easy to overeat from a giant bag. Pre-portioning is key.

Mixed Nuts (Lightly Salted or Unsalted)

• What to look for: Ingredients list that’s just nuts and maybe salt or a simple oil. Avoid versions with sugary coatings for daily snacking.


• Why it’s a win: Healthy fats, some protein, and minerals like magnesium.


• Portion guide: About 1/4 cup (a small handful) is usually 160–200 calories and enough for a snack.

Trail Mix (DIY or Lower-Sugar Versions)

Many commercial trail mixes lean dessert-like, with chocolate candies and sweetened dried fruit. You can still make this work.

• Option 1: Choose a pre-made mix with mostly nuts and seeds, minimal candy, and modest dried fruit.


• Option 2: Buy separate large bags of nuts, seeds, and unsweetened dried fruit and make your own lower-sugar mix at home.


• Monk fruit hack: If you miss a sweeter trail mix, sprinkle in a few chocolate chips or nuts coated with monk fruit or stevia-sweetened chocolate instead of regular candy.

Roasted Chickpeas, Lentils, or Broad Beans

Costco periodically carries crunchy roasted legumes.

• What to look for: >4–5 g protein and ≥3 g fiber per serving, moderate sodium, and minimal added sugar.


• Why it’s a win: Crunchy like chips but with more protein and fiber.

3. Low-Sugar and No-Added-Sugar Snacks

If you’re actively working to reduce added sugar—for blood sugar, weight management, or simply how you feel—Costco has more options than it used to. Always check the “Added Sugars” line on the Nutrition Facts panel.

Unsweetened or Lightly Sweetened Yogurt Drinks

• What to look for: Options that are either unsweetened or use small amounts of sugar combined with low-calorie sweeteners like monk fruit, stevia, or erythritol.


• Why it’s a win: Convenient, portion-controlled, and often kid-friendly.

Fruit Cups in 100% Juice or Water

Some Costco packs include fruit cups with no added sugar.

• What to look for: Labels that say “in 100% juice” or “in water,” and 0 g added sugar.


• Why it’s a win: Shelf-stable fruit option, useful for lunchboxes and travel.


• Note: Still a source of natural sugars, so pair with protein or fats (nuts, cheese) for better blood sugar balance.

Monk Fruit or Stevia–Sweetened Treats

Costco frequently rotates in snacks and treats sweetened with low- or zero-calorie sweeteners, including monk fruit and stevia. Availability varies by region, but you may see:

• Chocolate or protein bars sweetened with monk fruit, stevia, or erythritol.


• Low-sugar cookies or snack bites using these sweeteners instead of higher amounts of sugar.

These can be useful “bridge” foods if you’re used to very sweet snacks and are working your way toward a lower-sugar pattern. They’re still best enjoyed mindfully, but they can help reduce overall sugar intake without feeling restricted.

4. Fresh Produce Snacks (Minimal Prep, Maximum Nutrition)

One of the best uses of a Costco membership is loading up on produce that doubles as snack material.

Pre-Cut Veggie Trays and Snack Packs

• What to look for: Trays with carrots, celery, cucumbers, bell peppers, snap peas, or broccoli. The included dip may be higher in calories, so use it mindfully or swap in your own.


• Why it’s a win: The barrier to eating vegetables is often prep. When they’re washed and cut, you’re far more likely to snack on them.


• Dip ideas: Hummus, Greek yogurt dip, cottage cheese blended with herbs, or guacamole from Costco’s refrigerated section.

Mini Bell Peppers, Baby Carrots, and Snap Peas

These usually come in large bags and keep well.

• Why they’re a win: Crunchy, hydrating, and naturally low in calories and sugar.


• Snack combo: Veggies + hummus + a few olives for healthy fats.

Apples, Pears, Berries, and Grapes

Whole fruits are naturally sweet and come packaged with fiber, water, and micronutrients.

• What to look for: Big bags of apples or pears, clamshells of berries, or boxes of grapes.


• Serving suggestion: Pair fruit with a protein or fat source—string cheese, a handful of nuts, or Greek yogurt—to blunt blood sugar spikes and increase satiety.

5. Frozen Snacks and Smoothie Staples

The freezer aisle is a goldmine if you know what to look for.

Frozen Berries and Mixed Fruit

• What to look for: Ingredients list that’s just fruit—no added sugar or syrups.


• Why it’s a win: Perfect for smoothies, yogurt bowls, and cottage cheese. Frozen fruit is often as nutritious as fresh.


• Low-sugar smoothie idea: Blend 1/2 cup frozen berries, 1 scoop protein powder, unsweetened almond milk, and a small amount of monk fruit or stevia-based sweetener if you want more sweetness without extra sugar.

Frozen Edamame (In Shell or Shelled)

• Nutrition: About 8–11 g protein and 4–6 g fiber per 1/2 cup (depending on brand and form).


• Why it’s a win: A warm, savory snack option that feels substantial.


• Prep tip: Microwave, toss with a pinch of sea salt, garlic powder, or chili flakes.

Frozen Veggie Bites or Patties

Costco often carries vegetable-heavy patties or bites (e.g., kale bites, quinoa-veggie patties).

• What to look for: Vegetables listed first, reasonable sodium, and minimal added sugar.


• How to use: Bake a batch and keep in the fridge for a grab-and-go savory snack.

6. Kid-Friendly, Lower-Sugar Costco Snacks

If you’re feeding kids—or adults with kid-like taste buds—Costco can help you gently shift away from sugary snacks without a full revolt.

String Cheese and Mini Cheese Rounds

• Why it’s a win: Pre-portioned, high in protein and calcium, and usually 0 g added sugar.


• Pairing: Add a piece of fruit or a few whole-grain crackers.

Whole-Grain Crackers and Rice Cakes

• What to look for: Whole grain or brown rice as the first ingredient, ≤2–3 g sugar per serving.


• Serving ideas: Top with nut butter and sliced banana, or cheese and cucumber.

No-Sugar-Added Applesauce Pouches

• What to look for: Ingredients like “apples, water, ascorbic acid” and 0 g added sugar.


• Why it’s a win: Easy for lunchboxes and travel; still naturally sweet but less intense than candy.


• Balance tip: Pair with a protein source (nuts, cheese, yogurt) to reduce blood sugar swings.

Bars with Better Sugar Balance

Costco carries many snack and protein bars. They vary widely, so label reading is essential.

• What to look for: At least 8–10 g protein, ≥3 g fiber, and preferably ≤7 g added sugar per bar.


• Low-sugar options: Some bars use monk fruit, stevia, or erythritol to keep sugar lower. These can be useful replacements for traditional high-sugar granola bars.

7. How to Read Costco Snack Labels When You’re Cutting Added Sugar

Bulk shopping makes it extra important to choose wisely—if you buy a big box of something, you’ll likely eat it. Here’s a quick label strategy:

• Step 1: Check Added Sugars. Under “Total Sugars,” look for “Includes X g Added Sugars.” For daily snacks, try to keep this modest; ideally <5–7 g per serving.


• Step 2: Look at Fiber and Protein. Higher fiber and protein help your body handle sugars more smoothly and keep you full longer.


• Step 3: Scan Ingredients. The closer to whole foods (nuts, seeds, oats, fruit, dairy, eggs), the better. Sweeteners—whether sugar, honey, monk fruit, stevia, or others—should ideally appear lower on the list for everyday snacks.


• Step 4: Consider Your Personal Health Needs. If you have diabetes, prediabetes, PCOS, or are managing weight, leaning toward lower-sugar or no-added-sugar snacks can be especially helpful. Always coordinate with your healthcare team.

8. Using Monk Fruit and Other Natural Sweeteners with Costco Staples

One of the most powerful ways to reduce added sugar is to start with unsweetened or lightly sweetened Costco basics and customize them at home with natural, zero-calorie sweeteners.

Easy Low-Sugar Snack Ideas with Monk Fruit or Stevia

• DIY Yogurt Parfaits: Plain Greek yogurt + frozen berries + a sprinkle of nuts or seeds + a small amount of monk fruit or stevia-based sweetener. You get the taste of a dessert-style yogurt with far less sugar.


• Cottage Cheese “Cheesecake” Bowl: Blend cottage cheese with vanilla extract and a bit of monk fruit or stevia, then top with berries and a few crushed whole-grain crackers.


• Low-Sugar Trail Mix: Mix Costco nuts and seeds with unsweetened coconut flakes and a few pieces of monk fruit–sweetened chocolate for a treat-like snack that’s still lower in sugar than candy-heavy mixes.


• Fruit Dip: Combine plain Greek yogurt, cinnamon, and monk fruit or stevia-based sweetener to make a dip for apple slices or strawberries.

These approaches let you enjoy sweetness while keeping overall sugar intake more moderate, which can be supportive for energy levels, dental health, and metabolic health over time.

9. Putting It All Together: A Sample Costco Snack Plan

Here’s how a day of Costco-based snacks might look if you’re aiming for balanced, lower-sugar choices:

• Morning snack: Plain Greek yogurt with frozen berries and a bit of monk fruit sweetener.


• Afternoon snack: A small handful of mixed nuts and a clementine or small apple.


• Evening snack (if needed): Baby carrots and mini bell peppers with hummus, or a few roasted chickpeas.

This pattern keeps added sugar relatively low while providing protein, fiber, and healthy fats throughout the day.

Final Thoughts

Costco can absolutely support a healthy, lower-sugar lifestyle when you know what to look for. Focus on protein-rich dairy, nuts and seeds, legumes, fresh and frozen produce, and thoughtfully chosen bars and packaged snacks. Use natural sweeteners like monk fruit or stevia to customize sweetness at home rather than relying on heavily sweetened products.

Most importantly, aim for progress, not perfection. You don’t need to overhaul your entire cart at once. Even swapping one or two high-sugar snacks for more balanced options each trip to Costco can meaningfully shift your overall sugar intake and how you feel day to day.
