Breakfast

March 21, 2026

Let’s be honest, egg salad can sometimes feel a little… dated. But what if I told you we could transform this humble classic into something truly spectacular? Forget everything you know about bland, mushy egg salad. We’re talking about a rich, creamy, and perfectly textured filling, studded with crunchy sweet pepper and tangy relish, all piled high on a buttery, flaky croissant. This isn’t just a sandwich; it’s a lunchtime upgrade that’s ready in under 30 minutes. Get ready to fall in love with egg salad all over again!

Ingredients

• 4 large hard-cooked eggs, chopped
• 1/4 cup / 28g shredded Colby and Monterey Jack cheese
• 2 tablespoons / 30g sweet or dill pickle relish
• 2 tablespoons / 20g finely chopped red bell pepper
• 1/4 cup / 60g mayonnaise
• 1 1/2 teaspoons / 7.5g yellow mustard
• 4 large croissants, split
• 4 leaves red-tipped leaf lettuce
• Halved cherry tomatoes, for garnish (optional)
• For the Curried Variation
• 1/2 to 1 teaspoon curry powder
• For the Honey-Dill Variation
• 1 1/2 teaspoons / 7.5g honey mustard (in place of yellow mustard)
• 1 teaspoon dried dill

Instructions

1. In a medium bowl, gently combine the chopped hard-cooked eggs, shredded cheese, pickle relish, and finely chopped red bell pepper. Fold in the mayonnaise and mustard until everything is just combined. For the best flavor, cover and chill the mixture for at least 30 minutes, or up to 6 hours.
2. When you’re ready to serve, split the croissants. Place a leaf of lettuce on the bottom half of each croissant. Generously spoon the chilled egg salad mixture over the lettuce, then place the top half of the croissant on top.
3. If desired, secure each sandwich with a wooden toothpick threaded with a few cherry tomato halves before serving.
4. For the Variations
5. Curried Egg Salad: Prepare as directed, stirring 1/2 to 1 teaspoon of curry powder into the egg mixture with the mayonnaise. It’s essential to chill this version for at least 2 hours to allow the curry flavor to fully develop before assembling.
6. Honey-Dill Egg Salad: Prepare as directed, but substitute the yellow mustard with honey mustard and stir in 1 teaspoon of dried dill.

Pro Tips

• To avoid that unappealing green ring around the yolk, place your hard-cooked eggs in a bowl of ice water immediately after cooking to cool them down quickly.
• For an extra creamy texture, mash the egg yolks separately with the mayonnaise and mustard before folding in the chopped egg whites and other .
• Lightly toast the croissants before assembling for a delightful contrast of warm, crispy bread against the cool, creamy filling.
• The egg salad mixture is perfect for meal prep! Store it in an airtight container in the refrigerator for up to 3 days. Assemble the sandwiches just before serving to prevent soggy croissants.

FAQ
