Full Ingredients

For the Scramble

• 1 tbsp unsalted butter
• 1 tsp olive oil
• 1 small yellow onion, thinly sliced into half-moons (about 1 cup / 120 g)
• 4 large eggs
• 2 tbsp whole milk (30 ml)
• 1/8 tsp kosher salt (or to taste)
• 1/4 tsp freshly ground black pepper
• 4 oz cold-smoked salmon (lox), chopped into 1/2-inch pieces (115 g)
• 2 tbsp finely chopped fresh chives, divided

To Serve

• 2 bagels, split and toasted (plain, sesame, or everything)
• 1 tbsp capers, drained (optional)
• Lemon wedges (optional)

Step-by-Step Instructions

Step 1: Prep the aromatics and lox

Thinly slice the onion into half-moons. Finely chop the chives and set aside. Chop the cold-smoked salmon (lox) into 1/2-inch pieces so it folds easily into the eggs without clumping.

Step 2: Whisk the eggs

In a medium bowl, whisk together the eggs, milk, black pepper, and a small pinch of salt (lox is salty, so go light). Whisk just until uniform—overwhisking introduces too much air and can make the eggs dry.

Step 3: Toast the bagels

Toast bagels cut-side up until golden. Toaster: toast to your preferred shade. Oven: preheat to 375°F (190°C), place bagels cut-side up on a sheet pan, and toast 5–7 minutes. Keep warm while you cook the eggs.

Step 4: Sauté the onions

Heat a 10-inch nonstick skillet over medium heat. Add the butter and olive oil. When the butter foams, add the onion and a small pinch of salt. Cook, stirring occasionally, until the onion is soft and lightly golden at the edges, 6–8 minutes. If it browns too quickly, lower the heat.

Step 5: Start the scramble low and slow

Reduce heat to medium-low. Pour in the egg mixture. With a silicone spatula, gently push from the edges toward the center, creating soft curds. Cook until the eggs are mostly set but still glossy and custardy, 1–2 minutes. Avoid letting liquid pool, but do not overcook.

Step 6: Fold in lox and finish

Remove the skillet from the heat. Scatter the chopped lox and 1 tablespoon of the chives over the eggs. Fold gently until the lox is warmed through and the eggs remain silky, 15–30 seconds. Taste and adjust salt if needed. Spoon the scramble over toasted bagel halves, garnish with remaining chives, capers if using, and a squeeze of lemon. Serve immediately.

Pro Tips

• Cook the eggs on medium-low heat for soft, creamy curds—high heat makes them dry and rubbery.
• Season lightly: lox and capers add salt. You can always add a pinch at the end.
• Nonstick skillet + silicone spatula = delicate, uniform curds with minimal sticking.
• Add the lox off the heat; residual warmth keeps it tender and prevents it from turning tough.
• Warm bagels right before plating so the scramble stays hot on contact.

Variations

• Cream Cheese Swirl: Dot 2 tbsp room-temperature cream cheese into the eggs off heat and fold for a deli-inspired tang and extra richness.
• Herb Swap: Use thinly sliced scallions or a mix of chives and dill for a brighter, more aromatic finish.
• Gluten-Free or Different Base: Serve over a gluten-free bagel, toasted rye, or buttered sourdough for a different texture and flavor.

Storage & Make-Ahead

This scramble is best fresh. You can slice the onion and chop chives up to 2 days ahead (refrigerate in airtight containers). Keep lox refrigerated until just before cooking. If you have leftover scramble, cool quickly, refrigerate up to 1 day, and reheat gently over very low heat with a teaspoon of milk to restore creaminess. Toast bagels fresh; they can be frozen up to 3 months and toasted from frozen.
