Ingredients You’ll Need

Egg
Neutral oil
Dijon mustard
Lemon juice
’Nduja
Salt

Tomato Toast

Rustic or homemade everything bagel bread
Heirloom tomatoes
Salted butter
Maldon salt
Crushed red pepper flakes (optional)

How to Make It

Make the ’nduja mayo by blending egg, Dijon, and lemon juice, then slowly emulsifying in neutral oil until thick and creamy. Add ’nduja and season with salt. Pan-fry buttered bread until golden and crisp. Spread each slice generously with ’nduja mayo, top with thick slices of heirloom tomato, sprinkle with Maldon salt and crushed red pepper flakes, and enjoy immediately.

Tips for Success

Add the oil VERY slowly to ensure the mayo emulsifies.
Use room-temperature ingredients — mayo comes together easier.
Butter both sides of the bread for maximum crispness.
Use thick tomato slices so the toast stays juicy and substantial.
Maldon salt is key — adds crunch + enhances the tomato flavor.
Customize heat by adding more or less ’nduja or chili flakes.
Serve immediately — tomato toast is best fresh.
