Method
Make the Sriracha Mayo
1
In a small bowl, combine the mayonnaise, sriracha, and juice of half a lemon. Whisk until smooth and bright. Set aside.
Toast the Bread
2
Heat a frying pan over medium-high heat. Add butter and let it melt until foamy. Place bread slices in the pan and toast for 2-3 minutes per side until golden and crispy. Remove and set aside.
Cook the Spinach
3
In the same pan over medium-high heat, add a splash more butter if needed. Toss in the garlic cloves and cook for 30 seconds until fragrant. Add spinach straight from frozen — don't even think about thawing it. Season with salt and black pepper. Stir and cook for 3-4 minutes until wilted and any excess water has cooked off. Remove from heat.

Techniques
Safety & Storage
Cooking Temperature
Cook fried eggs until whites are fully set - 2 minutes for runny yolks, 3-4 minutes for fully set. Internal temperature should reach 145°F minimum.
When cooking spinach from frozen, ensure it reaches 165°F internal temperature to eliminate potential bacteria before consuming.
Cross Contamination
Use separate utensils and plates for raw eggs and ready-to-eat ingredients to prevent cross-contamination.
The same pan is reused for multiple steps - wash thoroughly or use separate pans if serving to immunocompromised individuals.
Handling
Crack eggs one at a time into a separate bowl before adding to pan to check for shell fragments and ensure freshness.
Storage
This dish is best served immediately after assembly. Do not store assembled sandwiches as the bread will become soggy.
High Risk Population
Pregnant individuals, elderly, and immunocompromised persons should ensure eggs are cooked to fully set yolks and spinach reaches safe internal temperature.
Allergen Warning
This recipe contains eggs and milk. Check store-bought mayonnaise for allergen statements as some brands may contain egg allergens.
Pro Tips
Technique
Don't thaw the spinach. Ever. Drop it straight from the bag into a screaming-hot pan with butter and garlic — the water clinging to the leaves is what gives you that gorgeous wilted texture without boiling it into oblivion.
Substitution
No sriracha? A few drops of hot sauce and a pinch of cayenne with the mayo and lemon will get you to the same bright heat. Keep it punchy, keep it fast.
From the chef
Here's the thing about that sad drawer of frozen spinach at the back of the freezer — it's not a fallback, it's the whole foundation. I built this sandwich the way I build everything: straight from frozen, high heat, and a pantry sauce that makes it taste like you had a plan. The egg yolk breaks into that garlicky spinach and the sriracha mayo ties it all together, and ten minutes later you have a sandwich that looks like you thought about it.
