Ingredients
Egg Custard
3 large eggs
White pepper, a pinch
Salt, a pinch
100 ml heavy cream
Vegetable Sauté
1 Tbsp olive oil
10 g butter (about ¾ Tbsp)
1 medium onion, finely diced
1 medium carrot, grated or finely diced
1 large bell pepper (any color), diced
2 medium tomatoes, chopped (or 1 cup canned diced tomatoes, drained)
2 garlic cloves, minced
½ tsp salt (plus more to taste)
¼ tsp chili flakes (adjust to heat preference)
¼ tsp freshly ground black pepper
1 tsp dried oregano
Assembly & Topping
1 tsp vegetable oil (to grease baking dish)
2 Tbsp chopped fresh parsley
150 g shredded cheese, divided (100 g for filling, 50 g for top)—Mozzarella, Gouda, or a mix
3 Tbsp breadcrumbs (panko or homemade)
Step-by-Step Cooking Directions
1 Season the Eggs
In a bowl whisk eggs with white pepper and a pinch of salt until frothy. Pour in cream; whisk again. Set aside to steep 10 minutes so flavors meld.
2 Sweat the Aromatics
Heat olive oil and butter in a wide skillet over medium. Add diced onion; sauté 2–3 minutes until translucent. Stir in carrot; cook 2 minutes.
3 Build Vegetable Base
Add bell pepper and sauté another 2 minutes, then fold in tomatoes and minced garlic. Sprinkle with ½ tsp salt and chili flakes. Cover, reduce heat to low, and simmer 5–7 minutes until vegetables soften and moisture reduces.
4 Season & Finish the Filling
Uncover; season with black pepper and oregano. Taste and adjust salt. Stir in 2 Tbsp chopped parsley. Remove from heat.
5 Prepare Baking Vessel
Grease a 25 cm (10-inch) oven-safe skillet or a 2-quart casserole with vegetable oil. Spread half of the vegetable mix on the bottom. Sprinkle 100 g shredded cheese over vegetables.
6 Combine Custard & Veg
Whisk egg mixture again and pour evenly over vegetables and cheese. Spoon remaining vegetables on top, gently pressing to submerge slightly.
7 Add Final Toppings
Scatter remaining 50 g cheese over surface. Sprinkle breadcrumbs for crunch.
8 Bake
Slide dish into preheated 190 °C / 375 °F oven. Bake 30 minutes, until custard is set, top is golden, and edges bubble.
9 Rest & Serve
Let casserole rest 5 minutes to firm up. Garnish with extra parsley. Slice into wedges and serve warm or at room temperature.

The Origins and Popularity of the Recipe
Baked egg-and-vegetable dishes have centuries-old roots across the Mediterranean basin. Spain’s tortilla española layers potato and egg; Italy’s frittata folds garden produce into a skillet; France’s clafoutis salés bakes custard with vegetables and cheese. This casserole borrows the stovetop sauté of a Provençal petit farci and the oven finish of an Italian crustless quiche, then modernizes it with a breadcrumb lid for textural snap. Social-media food creators embrace such dishes for their fridge-forgiveness—any leftover veg can star—making them viral under #CleanOutTheFridge, #MeatlessMonday, and #BrunchGoals.

Common Mistakes to Avoid

Over-baking: yields rubbery eggs—remove when center barely jiggles.
-
Under-seasoning custard: remember cream dilutes flavors; salt generously.

Using watery mozzarella only: mix with semi-hard cheese for better browning.

Beer: Belgian wit or a citrusy pale ale.

Cooking Tips
-
Beat eggs just until combined; over-whisking incorporates excess air, causing puff-and-collapse.
-
For extra umami, sprinkle 2 Tbsp grated Parmesan beneath breadcrumbs.
-
If using watery vegetables (zucchini, mushrooms), sauté until moisture evaporates.
-
Double the recipe in a 9×13-inch pan and add 5 minutes bake time for crowds.

Ingredient Spotlight – Oregano
A hallmark of Mediterranean cooking, oregano provides earthy, slightly minty depth. Rich in antioxidants like rosmarinic acid and carvacrol, it enhances both flavor and potential anti-inflammatory benefits. Use dried oregano here for concentrated flavor that stands up to oven heat; if substituting fresh, triple the quantity.

Keep this recipe in your repertoire for holidays, potlucks, or any day you crave sunshine on a fork—even if the weather says otherwise.
Frequently Asked Questions
1 Can I use half-and-half instead of heavy cream?
Yes, though the custard will be slightly lighter and may set a bit firmer.
2 How do I prevent my casserole from sticking?
Grease the dish well and, if using a skillet, ensure it’s oven-safe and well-seasoned.
3 Can I freeze leftovers?
Absolutely. Cool completely, wrap individual slices, and freeze up to 2 months. Reheat at 180 °C for 12 minutes.
4 What cheese melts best?
A mix of mozzarella for stretch and cheddar or Gouda for flavor gives ideal texture.
5 Is fresh oregano okay?
Yes—use 1 Tbsp chopped fresh in place of 1 tsp dried.

Swap cream for coconut cream and cheese for a meltable plant-based alternative.
7 My custard is watery—why?
Likely vegetable moisture. Cook down tomatoes and peppers thoroughly before assembly.
8 Does the breadcrumb topping have to be added?
No, but it adds crunch. Alternatively, use crushed nuts, seeds, or gluten-free crumbs.
9 How long can the assembled casserole sit before baking?
Up to 4 hours refrigerated. Bring to room temperature 15 minutes before baking.
