Ingredients for classic egg salad recipe with mustard
Six ingredients, nostalgic flavors, and a creamy tang that hits just right.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 8 whole | Freshly hard-boiled, peeled |
| Yellow Mustard 🍯 | ¼ cup | Dijon preferred for tang |
| Crisp Celery Stems 🧅 | 1 cup | Finely chopped, fresh |
| Red Onion 🧅 | ¼ cup | Finely diced, sharp variety |
| Fresh Dill 🌿 | 2 tbsp | Chopped, or sub dried |
| Mayonnaise 🥛 | ½ cup | High-quality, full-fat |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The eggs are non-negotiable—farm-fresh if you can get them, or the big carton from Kroger works fine. Hard-boil them 9 minutes in boiling water, then plunge into ice water for crisp whites. My grandmother swore by Dijon mustard for that sharp kick—French's or Maille are my go-tos, but any good yellow mustard does. Celery should be crisp, not limp, so grab the freshest bunch at the store. Pro tip: Trim the ends and store in a jar of water in the fridge to keep it crisp for days.
No Dijon? Yellow mustard plus a pinch of sugar gets you close. Fresh dill is ideal, but dried at half the amount works too. The mayo is where you can splurge—Hellmann's or Duke's are reliable, but homemade mayo (olive oil + egg yolks) takes it to the next level. Short on red onion? Green onions add a milder bite. And if you're feeling fancy, add a dash of smoked paprika for depth. The lemon juice brightens everything—don't skip it!
This salad tastes even better the next day as flavors meld. Store in an airtight container for 3-4 days in the fridge. To keep it creamy, press plastic wrap directly on the surface. For sandwiches, assemble just before serving so the bread doesn't get soggy. I always make a double batch—one for lunch, one to freeze for 2 months in a sealed container. Perfect for busy weeks!

Step-by-step instructions for classic egg salad with mustard
Here's how to make the perfect egg salad—creamy, tangy, and packed with fresh flavors.
Hard-Boil the Eggs to Perfection
Place the 8 whole large eggs in a saucepan and cover them with cold water by about 1 inch. Bring to a boil over high heat, then immediately reduce to a gentle simmer and cook for exactly 10 minutes. This timing ensures the yolks stay creamy without turning greenish.
Transfer the eggs to an ice bath for 10 minutes to stop the cooking process. Once cooled, peel the eggs under running water—this makes the shells slide off more easily. I like to tap the egg gently on the counter first to crack the shell all over before peeling. The eggs should be cool to the touch before chopping.
Chop the Eggs Finely for Texture
Place the peeled eggs in a large bowl and chop them into small, even pieces using a chef's knife. Aim for chunks about ¼-inch in size—this creates a perfect balance of creaminess and bite. I press down firmly on the knife with my palm to keep the pieces consistent.
Don't rush this step—uneven chopping leads to an uneven texture in your salad. If the eggs start to dry out, add 1 teaspoon of the lemon juice now to keep them moist while you work.
Mix the Mustard and Mayonnaise Base
In a separate bowl, combine the 0.25 cup yellow mustard and 0.5 cup mayonnaise. Use a fork to whisk until smooth and fully blended. The mustard should be evenly distributed—this is what gives your egg salad that classic tangy kick. I like to use Dijon mustard for a sharper flavor, but any yellow mustard will work.
Add the 0.25 cup finely diced red onion and 2 tablespoons chopped fresh dill to the mustard mixture. Stir well to incorporate. The onion adds a sharp bite, while the dill brings a bright, fresh note that balances the richness of the eggs and mayo.
Combine All Ingredients for Creamy Perfection
Add the chopped eggs to the mustard-mayo mixture and gently fold everything together using a silicone spatula. Be careful not to overmix—just combine until the eggs are fully coated. You want to preserve some texture, not turn it into a smooth paste.
Season with the 0.5 teaspoon salt and 0.25 teaspoon black pepper, then stir in the remaining 1 tablespoon lemon juice. Taste and adjust seasoning if needed—you might want a bit more salt or lemon for brightness. The salad should be tangy, slightly sharp, and perfectly balanced.
Add Crisp Celery for Freshness and Crunch
Finally, fold in the 1 cup finely chopped crisp celery stems until evenly distributed. The celery adds a refreshing crunch and helps cut through the richness of the eggs and mayo. Give everything one last gentle mix to ensure the celery is well incorporated.
Let the egg salad rest in the refrigerator for at least 30 minutes before serving. This allows the flavors to meld together beautifully. Serve on toasted bread, in sandwiches, or as a standalone dish with crackers. Enjoy immediately for the best texture and flavor!
Pro Tips For Making Classic Egg Salad Recipe With Mustard
- PEEL EGGS UNDER RUNNING WATER: The whites stick like glue when you try to peel them warm. Shock them in ice water for 5 minutes first, then roll gently between your palms under a slow stream of water—this loosens the membrane without tearing the yolks. I learned this the hard way after making a mess of three batches trying to peel them dry.
- USE ONLY THE WHITEST CELERY: The green parts of celery stems turn bitter and slimy when chopped. Cut off the pale white bottom 2 inches and discard the rest—you’ll get crisp, clean flavor without that off-taste. Trust me, your egg salad won’t taste like a sad office party snack.
- MIX MUSTARD IN LAST: Adding it too early makes the eggs watery. Start with just a teaspoon, then fold in the rest after everything else is combined. This keeps the texture creamy, not soggy. I used to dump it all in first and wondered why my salad always tasted diluted.
- CHOP ONION FINE AND REST IT: Tiny dice (about 1/8-inch) distribute flavor evenly without overpowering. Toss the chopped onion with a pinch of salt and let it sit for 10 minutes before mixing—this draws out moisture so it doesn’t make the salad watery. Sounds weird, but it works.
Common mistakes when making this recipe
Overcooking Eggs
I’ve ruined more egg salads than I care to admit by overcooking the eggs—greenish yolks and rubbery whites are a flavor killer. The key is precision: 9-10 minutes in boiling water, then an ice bath. My grandmother’s trick? Use a timer and never peek—the steam can lower the water temperature, throwing off your timing. If your yolks turn green, it’s from overcooking, not vinegar or anything else. 💡
Skipping the Ice Bath
Skipping the ice bath is a rookie mistake. Without it, eggs continue cooking in their residual heat, turning yolks grainy and whites tough. I learned this the hard way when I rushed and ended up with a salad that tasted like rubber. Fill a bowl with ice water, drop in the eggs for 10 minutes, then peel under running water. This keeps them cool and creamy.
Uneven Chopping
Lumpy egg salad is a texture crime. Chopping eggs into uneven pieces means some get mushy while others stay firm. Use a sharp chef’s knife and press down firmly with your palm for consistency. I like to chop the eggs into ¼-inch chunks—this gives the perfect balance of creaminess and bite. If the eggs start drying out, add a splash of lemon juice to keep them moist.
Overmixing the Salad
Overmixing turns egg salad into a paste, losing all texture. After combining the eggs with the mustard-mayo mixture, gently fold just until everything is coated. Use a silicone spatula to avoid crushing the eggs. The goal is a creamy yet slightly textured salad—like a cross between a smooth dip and a chunky spread. 🥚
Using Old or Poor-Quality Eggs
Freshness matters more than you’d think. Older eggs have thinner whites and more watery yolks, which makes the salad watery and less flavorful. Always use farm-fresh eggs or the freshest carton from the store. If you’re unsure, float them in water—if they sink, they’re fresh enough. I also avoid eggs with any cracks, as they can make the salad taste off.
Ignoring the Resting Time
Rushing to serve egg salad right after mixing means missing out on flavor development. Let it rest in the fridge for at least 30 minutes—this lets the mustard’s tang and the dill’s freshness meld with the eggs. I often make it the night before, and it tastes even better the next day. Patience here makes all the difference in balancing the flavors. ✨

Frequently asked questions
Can I substitute mayonnaise with something lighter?
For a lighter version, replace half the mayo with Greek yogurt or light mayo—just reduce the mustard slightly to balance the tang. I've also used avocado mash (2 tbsp) for creaminess with a different flavor profile. The key is keeping the texture similar by adjusting liquid ratios.
How do I keep the celery crisp longer?
Store celery stems in a jar of water in the fridge—this keeps them crisp for 5-7 days. For extra crunch in your salad, add the chopped celery just before serving. If using pre-chopped celery, sprinkle with 1 tsp lemon juice before mixing to preserve freshness.
What's the best way to reheat leftover egg salad?
Egg salad isn't ideal for reheating—it can get rubbery. Instead, make a fresh batch when ready to eat. If you must reheat, warm gently in a microwave-safe bowl for 20-30 seconds on low power, then stir and add a splash of milk or lemon juice to restore creaminess. For sandwiches, assemble with fresh egg salad.
Can I make this with hard-boiled chicken instead of eggs?
Use 1 cup chopped cooked chicken breast along with the eggs for a protein-packed version. Reduce the mayo by 2 tbsp since chicken holds moisture. The mustard and celery still work perfectly—this makes great sandwiches or wraps for a heartier meal.
Why does my egg salad taste bland?
Most likely, you need more acidity or salt. Boost flavor by adding 1 extra tbsp lemon juice or ½ tsp Dijon mustard. If using store-bought mustard, it might be too mild—try prepared mustard with a pinch of sugar to enhance the tang. Always taste as you go!
