Ingredients and Substitutions

Essential Ingredients

• 1 protein bagel (homemade or store-bought)
• 1 large egg
• ¼ ripe avocado
• 1 to 2 tablespoons pickled onions
• 1 to 2 slices emmental cheese
• Pinch of za’atar
• Drizzle of spicy mayo or hot sauce
• 1 teaspoon olive oil or butter for frying
• Salt and black pepper to taste

Notes on Ingredient Quality

Bagels: This recipe is made even better when using homemade bagels. For a protein boost, try the Greek yogurt-based recipe from this post on Bake With Lina. If you're after a traditional bagel base, the New York Style Bagels are also excellent.

Eggs: Use fresh eggs for the best texture and flavor. A free-range egg will have a richer yolk that brings more color and creaminess to your sandwich.

Cheese: Emmental cheese is ideal for its smooth melt and nutty flavor, but cheddar or American cheese work well too.

Pickled Onions: If making your own, prepare a small batch in advance and store it in the fridge for up to two weeks. Their zingy flavor adds a tangy balance that cuts through the richness of the other ingredients.

Substitutions to Fit Your Needs

• Bagel: Use a gluten-free bagel or whole wheat version for added fiber. You can also explore this classic homemade recipe for another great base.
• Egg: Swap with scrambled eggs or a tofu scramble if you’re avoiding yolks or following a vegan diet.
• Cheese: Dairy-free slices or nutritional yeast work well for non-dairy options.
• Avocado: Hummus, mashed peas, or cream cheese are great alternatives if avocados aren’t available.
• Seasoning: If you don’t have za’atar, try oregano, Italian seasoning, smoked paprika, or chili flakes.

How to Make a High Protein Breakfast Bagel Sandwich

Step-by-Step Instructions

1. Toast the Bagel
   Slice the bagel in half and toast it in a toaster, skillet, or air fryer until lightly golden.
2. Prepare the Avocado
   Slice or smash the avocado and spread it onto the bottom half of the toasted bagel.

3. Cook the Egg
   In a non-stick skillet, heat olive oil over medium heat. Crack in the egg, keeping the yolk intact. Season with salt, pepper, and a generous pinch of za’atar. Cover with a lid and cook until the white is set and the yolk is still runny, about 2 to 3 minutes. Flip the egg for over-medium if preferred.
4. Assemble the Layers
   Place the egg on top of the avocado, then layer the cheese on top while the egg is still warm to encourage melting.

5. Add Pickled Onions
   Spoon 1 to 2 tablespoons of pickled onions on top of the cheese.
6. Drizzle with Sauce
   Finish with a light drizzle of spicy mayo, sriracha, or your favorite hot sauce.

7. Finish and Serve
   Close with the top half of the bagel, press gently, and slice in half. Serve immediately.

Expert Tips and Tricks

Best Practices

• Toast Only the Inside: For a nice contrast in texture, toast just the cut sides of the bagel.
• Melt the Cheese: Add cheese while the egg is still hot, or briefly cover the pan to help it melt.
• Perfectly Ripe Avocados: Use avocados that yield slightly to pressure. If they’re overripe, mash with lemon juice for an easy spread.

Common Mistakes to Avoid

• Overcooking the Egg: Watch closely to maintain a runny yolk if that’s your preference.
• Skipping the Sauce: The spicy mayo or hot sauce ties the flavors together. Even a dash makes a big difference.
• Using Cold Ingredients: Allow cheese or pickled onions to come to room temp before assembling for better blending of flavors.

Time-Saving Hacks

• Make your bagels in advance and freeze. Reheat in an air fryer or toaster oven.
• Batch prep pickled onions to use in salads, tacos, and sandwiches all week.
• Cook multiple eggs at once if feeding a crowd. Use a griddle or larger pan for efficiency.

Serving Suggestions

What to Serve With Your Breakfast Bagel

• Fresh fruit like sliced apples, oranges, or berries adds a refreshing contrast.
• A simple green salad with lemon vinaigrette balances the richness of the sandwich.
• Hash browns or sweet potato wedges make it a full brunch experience.

How to Plate It Beautifully

• Cut the bagel sandwich in half and stack both pieces slightly on a plate.
• Garnish with extra za’atar, a few avocado slices, or microgreens for a bright finish.
• Serve on a wooden board with fruit and a dipping sauce for an Instagram-worthy presentation.

Beverage Pairings

• An iced latte or strong black coffee balances the savory richness.
• A citrus smoothie or green juice complements the bold flavors and adds a health boost.
• For special brunches, serve with a non-alcoholic Bloody Mary or sparkling water with lemon.

Storage and Reheating

Storing Leftovers

• Wrap the sandwich tightly in foil or reusable wrap.
• Store in the refrigerator for up to 3 days.
• For best results, remove avocado and pickled onions before storing and add them fresh after reheating.

How to Reheat

• Oven or toaster oven: 350°F for 6 to 8 minutes.
• Air fryer: 3 to 4 minutes until heated through.
• Microwave: 30 to 45 seconds (remove fresh toppings first to avoid sogginess).

Freezer Option

• Assemble the sandwich without avocado or onions.
• Wrap in foil and freeze for up to 1 month.
• Thaw overnight in the fridge and reheat as above. Add fresh toppings before serving.
