Ingredients for 21 day fix egg salad
Six eggs, Greek yogurt, and fresh veggies—this light yet satisfying salad keeps your 21 Day Fix on track.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 6 whole | Hard-boiled, peeled, chopped |
| Nonfat Plain Greek Yogurt 🥛 | ½ cup | Full-fat for creaminess (optional) |
| Dijon Mustard 🌶️ | 1 tbsp | Tangy variety preferred |
| Fresh Celery 🧅 | ½ cup | Finely chopped, crisp texture |
| Red Onion 🧅 | 2 tbsp | Finely diced, mild flavor |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For moisture and richness |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed, brightens flavor |
| Salt 🧂 | ½ tsp | Kosher or sea salt preferred |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground for best flavor |
| Avocado 🥑 | ½ whole | Optional, mashed for healthy fats |
| Whole-Grain Bread 🍞 | 4 slices | For serving, optional |
The Greek yogurt is non-negotiable here—it keeps things creamy without the mayo guilt. Nonfat Fage or Siggi’s are my go-tos, but any plain Greek yogurt works. For the eggs, room-temperature eggs boil faster and stay firmer. If you're prepping ahead, boil a batch on Sunday and store them in the fridge for the week. The celery and red onion add crunch and freshness, so don’t skip them. Pro tip: Soak the chopped celery in cold water for 10 minutes before mixing to keep it crisp longer.
No Greek yogurt? Light mayo or extra nonfat yogurt gets you close, but the texture won’t be as smooth. Swap red onion for green if you prefer milder flavor—just dice it extra fine. Avocado is optional but adds healthy fats that keep you full. Ripe avocados mash easily—look for ones that yield slightly to gentle pressure. For extra protein, add chopped hard-boiled chicken or turkey breast. And if you’re watching carbs, skip the bread and serve it over greens instead.
This salad keeps beautifully for 3-4 days in the fridge, though the avocado will turn brown faster. Store it in an airtight container with a layer of plastic wrap pressed right on top to keep the celery crisp. For meal prep, portion it into small containers with a slice of whole-grain bread on the side. It reheats well too—just pop it in the microwave for 20 seconds if it’s lost its crunch. Perfect for lunches all week!

Step-by-step instructions for protein-packed egg salad
Here's how to make the perfect egg salad that's creamy, fresh, and packed with flavor.
👨🍳 Step 1: Hard-Boil the Eggs Just Right
Place the 6 whole large eggs in a saucepan and cover them with cold water by about 1 inch. Bring to a rolling boil over high heat, then immediately remove from heat, cover, and let sit for 12 minutes. This timing ensures perfectly cooked yolks that stay creamy—not dry or rubbery.
Transfer the eggs to an ice bath for 10 minutes to cool completely. Once cool, peel the eggs under running water for easier removal of shells. Chop the eggs into ¼-inch pieces using a sharp chef's knife or pulse in a food processor for a smoother texture. I like to keep mine slightly chunky for better texture, but you can go finer if you prefer.
👨🍳 Step 2: Mix the Creamy Base
In a medium bowl, combine the chopped eggs with the 0.5 cup nonfat plain Greek yogurt, 1 tbsp Dijon mustard, 1 tbsp extra-virgin olive oil, and 1 tbsp lemon juice. Use a fork or silicone spatula to gently fold everything together—you want to mix just enough to combine without mashing the eggs completely. The yogurt adds creaminess while keeping it light.
Season with 0.5 tsp salt and 0.25 tsp ground black pepper. Taste and adjust if needed—this is your flavor foundation. If you're using the optional 0.5 whole avocado, mash it with a fork and fold it in now for extra richness and healthy fats. The avocado adds a silky texture that balances the egg's firmness.
🥘 Step 3: Add Crunchy Fresh Vegetables
Finely chop the 0.5 cup fresh celery into tiny pieces—think almost like a brunoise cut. Dice the 2 tbsp red onion into very small pieces so they distribute evenly without overpowering the flavor. Fold these into the egg mixture and stir gently to combine. The celery adds a crisp texture, while the onion brings a subtle sweetness that brightens everything.
Let the salad sit for 5 minutes to allow the flavors to meld. This resting time is key—it lets the mustard and lemon juice mellow out slightly and the yogurt fully coat the eggs. If you're short on time, skip this step, but I promise the wait makes a difference!
🍽️ Step 4: Serve on Whole-Grain Bread
Toast the 4 slices whole-grain bread lightly if desired—this adds a nice crunch. Spoon the egg salad onto the bread slices, creating a generous layer. For extra flair, top with a sprinkle of freshly cracked black pepper or a drizzle of extra-virgin olive oil for added richness.
This egg salad keeps well in the fridge for up to 3 days, making it perfect for meal prep. Store it in an airtight container, and when ready to eat, give it a quick stir to revive the textures. The whole-grain bread adds fiber and heartiness, while the protein-packed filling keeps you satisfied for hours—ideal for your 21 Day Fix plan!
Pro Tips For Making 21 Day Fix Egg Salad
- PEEL EGGS COLD: I used to rush this and end up with egg shells clinging like glue. Grab a bowl of ice water, crack the eggs in, and let them chill for 5 minutes—peeling becomes effortless, and you’ll avoid that frustrating yolk-on-shell situation.
- USE FULL-FAT CELERY: The 21 Day Fix version skips it, but if you’re upgrading, grab the thick ribs with those stringy bits—they add a satisfying crunch and texture. Trim the ends, slice into ¼-inch pieces, and toss in right after the eggs cool.
- MIX YOGURT LAST: Adding the Greek yogurt too early makes the salad watery. Let the eggs, mustard, and onions sit for 10 minutes after chopping—this lets flavors meld before the yogurt binds everything together. Stir in just before serving.
- SALT THE ONIONS: Raw red onion is sharp, but if you’re sensitive to bite, soak the slices in ¼ cup cold water with a pinch of salt for 5 minutes. Drain well and pat dry—this mellows the flavor without losing texture, and your mouth won’t rebel mid-bite.
Essential equipment for perfect results
Basic Mixing Bowl
You don’t need anything fancy here—a medium-sized mixing bowl with a capacity of 2-3 cups works perfectly. I use a Pyrex glass bowl because it’s non-reactive and easy to clean, but any stainless steel or ceramic bowl will do.
The key is choosing one with a non-slip base so it doesn’t slide around while you mix. Avoid plastic if possible—it can absorb odors over time, especially with ingredients like Dijon mustard and lemon juice. 🥛
Sharp Knife & Cutting Board
A sharp chef’s knife (8-inch) is essential for chopping eggs and vegetables evenly. I recommend a Wüsthof or Victorinox—they stay sharp longer and make quick work of celery and onions. Pair it with a cutting board that won’t dull your blade; a bamboo or high-density plastic board is ideal.
For extra precision, use a microplane to grate the red onion finely—it’s faster than dicing and distributes flavor more evenly. 🧅
Measuring Tools
Accurate measurements make all the difference in this recipe. Grab a liquid measuring cup for the Greek yogurt and lemon juice, and a set of dry measuring spoons for the Dijon mustard, salt, and pepper.
I keep a small kitchen scale handy for weighing ingredients like the Greek yogurt if I’m feeling precise—just 120 grams for the ½ cup. For the olive oil, a small squeeze bottle or measuring spoons works best. Precision here keeps the balance of flavors spot-on. 🫒
Optional: Food Processor
If you prefer a smoother texture, a mini food processor or immersion blender speeds up the process. Pulse the chopped eggs for 3-5 seconds to break them down without overmixing. I use my Ninja Mini Food Processor—it’s compact, affordable, and does the job perfectly.
For the avocado, if you’re adding it, a fork works fine, but a potato masher gives you more control over the texture. 🥑
Storage Containers
For meal prep, airtight glass containers are a must. I use Leviton glass jars (16 oz) with snap-on lids—they stack neatly in the fridge and keep the salad fresh for 3-4 days.
If you’re storing it with avocado, add the avocado just before serving to prevent browning. For reheating, a microwave-safe glass bowl works best—just cover with a damp paper towel to retain moisture. 💫
Nutrition facts
Frequently asked questions
Can I use regular mayo instead of Greek yogurt?
You can, but it won't align with the 21 Day Fix goals. Light mayo has fewer calories, but Greek yogurt keeps it creamy while adding protein and probiotics. For a lighter mayo option, mix ¼ cup light mayo with ¼ cup Greek yogurt to cut calories while maintaining texture.
How do I keep the egg salad from getting watery?
Drain the chopped eggs well after peeling, and avoid overmixing. Use a paper towel to pat them dry before adding to the bowl. Also, let the salad sit for 5 minutes before serving—this helps the yogurt fully absorb into the eggs. If it still seems too wet, add 1 extra tbsp of Dijon mustard to help bind it.
What are the best bread options for this recipe?
Whole-grain bread is ideal, but you can also use rye, sourdough, or low-carb options like lettuce wraps. For extra protein, try Ezekiel bread or a high-fiber tortilla. If you're watching carbs, skip bread entirely and serve it over greens or cucumber slices for a refreshing twist.
Can I prep this egg salad ahead of time?
Yes! Store it in an airtight container for 3-4 days in the fridge. Keep the avocado separate until serving to prevent browning. If the celery loses crispness, toss it with 1 tsp lemon juice before adding back to the salad. For best texture, stir it well before eating to revive the flavors.
Is this egg salad safe for meal prep?
but follow food safety tips. Store in separate containers if adding avocado, and keep the salad refrigerated at 40°F or below. Reheat in the microwave for 20 seconds if needed, but avoid reheating if using avocado. Label containers with dates to track freshness. This recipe is perfect for 21 Day Fix meal prep—just portion into single servings for easy grab-and-go lunches!
