Crispy Egg Salad Open Faced Toastie with Feta (High Protein)
This Crispy Egg Salad Open Faced Toastie is the high protein lunch that takes 15 minutes and tastes like something you would order at a good cafe. Creamy egg salad made with Greek yogurt instead of mayo, Dijon mustard, honey, red pepper, jalapeño, and red onion piled onto toasted sourdough and topped with crumbled feta, then crisped in the air fryer or under the broiler until the feta is lightly golden and everything on top is warm and slightly crispy. No oil, no mayo, genuinely satisfying, and completely nourishing.
Ingredients you’ll need:
- Large Eggs: Two hard boiled eggs peeled and chopped are the protein foundation of the entire recipe. Cook to a firm yolk for the best egg salad texture that holds together on the toast.
- Large Red Pepper: Diced small for a sweet crunch that adds color and freshness to the egg salad. Any color bell pepper works but red is the sweetest and most visually vibrant.
- Small Red Onion: Finely diced for a sharp bite that balances the creamy egg salad. If raw red onion is too strong for your taste soak the diced pieces in cold water for 5 minutes before using.
- Jalapeño: Finely chopped for a gentle heat throughout the filling. Remove seeds entirely for a mild result or leave some in if you love heat.
- Greek Yogurt: Replaces mayo entirely as the creamy binder. Full fat Greek yogurt gives the richest, most satisfying result. This is what makes the recipe oil free and significantly higher in protein than a traditional egg salad.
- Yellow or Dijon Mustard: Adds a tangy, savory depth that makes the egg salad taste properly seasoned and complex. Dijon gives a more sophisticated flavor while yellow is more classic.
- Honey: Just half a teaspoon to balance the tanginess of the yogurt and mustard. Do not skip this as it rounds out the whole filling beautifully.
- Sourdough Bread: One thick slice toasted until properly golden and crisp before adding the egg salad. Sourdough holds up to the topping and crisping process better than any other bread.
- Feta Cheese: Crumbled generously over the top before crisping. Feta adds a salty, tangy contrast that takes this toastie from good to genuinely extraordinary.
Why You'll Love This Crispy Egg Salad Open Faced Toastie
1. High Protein and Completely Oil Free: Greek yogurt replacing mayo and two whole eggs make this one of the most protein-rich open faced toasties you can make at home with zero added oil anywhere in the recipe.
2. The Air Fryer Crisp is the Game Changer: Crisping the assembled toastie in the air fryer or under the broiler transforms it from a cold sandwich into something warm, slightly golden, and deeply satisfying in a way a regular cold egg salad toast never could be.
3. Ready in 15 Minutes: From boiling the eggs to pulling the toastie from the air fryer takes under 15 minutes. One of the fastest genuinely nourishing meals you can make on a busy day.
4. The Feta Makes Everything Better: Crumbled feta crisped over the top of the egg salad adds a salty, slightly caramelized layer that makes every bite taste significantly more complex and special than a standard egg salad sandwich.
5. No Mayo Required: Greek yogurt creates a creamy, tangy binding that is lighter, higher in protein, and more flavorful than mayo. Once you make egg salad this way you will not go back.
6. Perfect for Breakfast or Lunch: This toastie works equally well as a quick protein-packed breakfast or a satisfying lunch. Versatile, fast, and filling enough to keep you going for hours.
7. Completely Customizable: Add avocado slices on top, swap jalapeño for chili flakes, use a different bread, or add fresh herbs like dill or chives. The base recipe works beautifully with endless small variations.
How to Make Crispy Egg Salad Open Faced Toastie
Step 1: Prepare the Egg Salad Hard boil the eggs, peel, and chop into small pieces. Add to a bowl along with diced red pepper, finely diced red onion, finely chopped jalapeño, Greek yogurt, mustard, honey, salt, and black pepper. Stir until creamy and evenly combined. Taste and adjust seasoning.
Step 2: Assemble the Toastie Toast the sourdough bread until golden and properly crisp. Spread the egg salad evenly and generously over the entire surface of the toast right to the edges. Crumble feta cheese generously over the top of the egg salad covering as much of the surface as possible.
Step 3: Crisp Preheat air fryer to 375°F or set oven broiler to high. Place the assembled toastie in the air fryer for 4 to 5 minutes or under the broiler for 3 to 5 minutes until the feta is lightly golden and the edges of the egg salad look slightly crispy. Watch closely in the last minute as the feta can go from golden to burnt quickly.
Step 4: Serve Remove from heat and let cool for 1 minute before eating as the filling will be very hot straight from the air fryer. Serve immediately for the best crispy texture.

Tips for the Best Crispy Egg Salad Toastie
1. Toast the Bread Before Adding the Filling: Starting with properly toasted bread means the base stays crispy even after the toastie goes back into the air fryer. Untoasted bread becomes soggy under the egg salad before it has a chance to crisp up.
2. Chop the Eggs Small: Smaller, more uniform egg pieces distribute more evenly across the toast and create a better surface for crisping. Large chunks slide off and create uneven bites.
3. Use Full Fat Greek Yogurt: Full fat Greek yogurt is thick enough to hold the egg salad together without any excess moisture. Low fat yogurt can make the filling watery which results in soggy toast.
4. Crumble the Feta Generously: More feta means more golden crispy pockets across the surface. Do not be shy with it. A generous crumble gives you the best visual and the best flavor after crisping.
5. Watch the Broiler Closely: Broiler intensity varies significantly between ovens. Check every minute during the crisping step rather than walking away. The difference between perfectly golden feta and burnt feta is about 60 seconds.
6. Let it Rest One Minute Before Eating: The filling holds its shape much better after a brief 1 minute rest. Cutting or biting into it immediately straight from the air fryer causes everything to slide off.
7. Soak the Red Onion if Sensitive: Raw red onion can be quite sharp. A 5 minute soak in cold water before dicing removes the harshness while keeping the crunch and flavor. Worth doing if you find raw onion overwhelming.
How to Store
1. Egg Salad Filling: Store the egg salad filling separately in an airtight container in the refrigerator for up to 3 days. Assemble and crisp the toastie fresh each time for the best texture.
2. Assembled Toastie: The assembled toastie is best eaten immediately after crisping. It does not store well assembled as the bread softens quickly once topped.
3. Make Ahead for Meal Prep: Make a larger batch of egg salad filling at the start of the week and store refrigerated. Assembly and crisping takes under 5 minutes making this one of the fastest meal prep lunches available.
4. Reheating: If you have a leftover assembled toastie reheat in the air fryer at 350°F for 2 to 3 minutes to bring back some crispness. Avoid microwaving as it makes the toast completely soft.
5. Hard Boiled Eggs: Boil a batch of eggs at the start of the week and store peeled in a container of cold water in the refrigerator for up to 5 days. Ready to chop and use for egg salad any time.
Frequently Asked Questions
Can I use mayo instead of Greek yogurt? Yes. Mayo works as a direct substitute in equal amounts for a more traditional egg salad flavor. Greek yogurt is preferred for the higher protein content and lighter result but both are delicious.
Can I make this without an air fryer? Yes. The oven broiler on high works equally well. Place the assembled toastie on a baking sheet on the top rack under the broiler for 3 to 5 minutes until the feta is lightly golden. Watch closely throughout.
What bread works best for this toastie? Sourdough is the best choice for its structure and flavor but any thick-cut bread that toasts well works. Rye bread, wholegrain, or a seeded loaf all work beautifully. Avoid soft sandwich bread as it becomes too soft under the filling.
Can I add avocado to this toastie? Yes. Sliced or smashed avocado layered under or over the egg salad adds creaminess and healthy fats that complement the filling perfectly. Add it after crisping rather than before to keep it fresh.
Is this recipe gluten free? The egg salad filling is naturally gluten free. Simply use a certified gluten free bread to make the entire toastie gluten free.
Can I use cottage cheese instead of Greek yogurt? Yes. Blend cottage cheese completely smooth before using in place of Greek yogurt in equal amounts. The flavor is very similar and the protein content is actually slightly higher.
How do I hard boil eggs perfectly for egg salad? Place eggs in cold water, bring to a boil, then cook for exactly 10 minutes. Transfer immediately to an ice bath for 5 minutes. This gives you a fully set but not rubbery yolk that chops beautifully for egg salad.
