Method
In a large frying pan over medium heat, melt the butter until it foams. Add the onion and cook, stirring occasionally, until softened and translucent, about 5 minutes.
In a bowl, whisk together the eggs, heavy-cream, mustard, salt, and black-pepper until well combined. The mustard should be emulsified, not sitting at the bottom like a afterthought.
Spread the spinach mixture evenly in the prepared baking dish. Pour the egg mixture over the top, ensuring even distribution.
Scatter the cheddar-cheese over the surface in a single layer. Do not pile it — a proper, even coverage is all you need.
Rest for 5 minutes before serving. Breakfast is not a race.

Frying PanSafety & Storage
Cooking Temperature
Bake for full 25-30 minutes until eggs are set and center reaches safe temperature. A slight wobble in the center is acceptable but eggs must not be runny.
High Risk Population
This dish contains eggs and should be fully cooked. Elderly, pregnant women, young children, and immunocompromised individuals should ensure eggs are cooked to proper doneness.
Cross Contamination
Use separate cutting boards and utensils for raw egg mixture and vegetables. Clean all surfaces that contact raw eggs thoroughly before using for other ingredients.
Handling
Beat eggs in a clean bowl and use clean whisk or fork. Avoid tasting the raw egg mixture before baking.
Storage
Refrigerate leftovers within 2 hours of serving. Store in airtight container and consume within 3-4 days.
Shelf Life
This dairy and egg dish is highly perishable. Do not leave at room temperature for more than 2 hours total including serving time.
Pro Tips
Technique
When whisking the egg mixture, keep going until the mustard is fully emulsified into the cream. If it's pooling at the bottom, you'll get bites of sharp mustard and bites of nothing—a crime against the eggs and yourself.
Substitution
If cheddar feels too obvious, aged Gruyère or Comté works beautifully here. But don't reach for pre-shredded cheese—those anti-caking agents will leave you with a rubbery surface instead of proper golden crust.
Make Ahead
Wilt the spinach and onion the night before, store it in a sealed container, and you're left with only assembly and baking in the morning. The eggs wait for no one, but the vegetables don't mind waiting for them.
From the chef
I created this bake the morning I closed my restaurant and watched the velvet ropes finally collapse under nothing but their own pretense. This is breakfast without the performance: eggs, spinach, and a mustard cream that actually tastes of mustard—not a whisper of it hiding in the corner of your palate. The cheese crowns it in gold while you sit down, properly, at a table meant for eating, not posing. No reservations required. No brunch required at all, actually.
