🧺 Ingredients
Base
4–5 buttery croissants, slightly stale or fresh, cut into large cubes
Vegetables
2 cups fresh spinach, chopped
1 small onion, finely chopped
1 clove garlic, minced
1 tbsp olive oil
Cheese
½ cup feta cheese, crumbled
1 cup Gruyere cheese, shredded

1½ cups milk (or cream for extra richness)
½ tsp salt
¼ tsp black pepper
¼ tsp nutmeg (optional, for warmth)
🍽️ Instructions
Step 1: Prep the Croissants
Cut croissants into cubes and place in a lightly greased baking dish.
Step 2: Cook Spinach
Heat olive oil in a pan. Sauté onion until soft, add garlic, then spinach until wilted. Let cool slightly.
Step 3: Assemble Strata
Sprinkle feta and Gruyere over croissant cubes.
Evenly layer sautéed spinach and onions.
Repeat if needed for extra layers.
Step 4: Make Custard
Whisk eggs, milk, salt, pepper, and nutmeg.
Pour evenly over croissant mixture, pressing lightly so the bread absorbs the liquid.
Let soak 10 minutes (or refrigerate overnight for make-ahead).
Step 5: Bake
Preheat oven to 180°C (350°F).
Bake uncovered for 35–40 minutes until puffed, golden, and set in the center.
Step 6: Serve
Cool 5 minutes, slice, and serve warm.
💡 Tips
Use slightly stale croissants — they hold up better to custard.
Make ahead: assemble the night before and bake fresh in the morning.
Add herbs like thyme or chives for extra flavor
Can add mushrooms or roasted red peppers for variation.
