It’s seasoned with gochujang for a gentle kick and finished with a creamy, custard-like filling—chilled, not baked—for a refreshing twist that’s ideal for hot days and outdoor gatherings. A true fusion of Korean tradition and creative no-bake technique!

Ingredients

Seasonal produce and bold Korean flavors create a quiche unlike any other. The panko crust provides a crisp, buttery base, while bulgogi and summer vegetables bring color, texture, and vibrancy. Fresh thyme and chives add a summery garden touch.

For the No-Bake Panko Crust

• 200 g panko breadcrumbs: for a light, crisp texture
• 80 g unsalted butter, melted: binds the crust and adds richness
• 1/2 tsp fine sea salt: for seasoning
• 1 tbsp fresh thyme leaves, chopped: seasonal fragrance

For the Korean Bulgogi Filling

• 250 g beef sirloin, thinly sliced: classic for bulgogi
• 2 tbsp soy sauce, 1 tbsp brown sugar, 1 tbsp sesame oil, 1 tbsp mirin, 2 garlic cloves (minced), 1/2 tsp black pepper: for an authentic bulgogi marinade

For the Grilled Veggies

• 1/2 small red onion, 1/2 red bell pepper, 1 small zucchini, 50 g shiitake mushrooms: summer vegetables for color and flavor
• Vegetable oil: for grilling

For the No-Bake Custard & Assembly

• 3 large eggs
• 250 ml heavy cream
• 120 ml whole milk
• 1 tbsp gochujang (Korean chili paste): adds a spicy-sweet depth
• 1 tsp Dijon mustard
• 1/2 tsp salt
• 50 g grated Emmental cheese, 50 g grated mozzarella cheese: for melt and flavor
• 1 tbsp chives, 1 tbsp sesame seeds: garnish and extra flavor

Instructions

Step 1: Prepare the No-Bake Panko Crust

In a mixing bowl, combine panko, melted butter, salt, and chopped thyme. Mix until the crumbs are evenly moistened. Press firmly into the base and slightly up the sides of a 20-cm springform pan lined with plastic wrap. Use a flat-bottomed glass to compress. Chill in the refrigerator for at least 1 hour to set—this step ensures your crust holds together when slicing.

Step 2: Marinate the Bulgogi Beef

In a bowl, mix soy sauce, brown sugar, sesame oil, mirin, minced garlic, and black pepper. Add sliced beef, tossing to coat. Cover and marinate in the fridge for 30 minutes. This allows the beef to absorb all the classic Korean barbecue flavors.

Step 3: Grill the Vegetables and Bulgogi

Brush grill pan or grill grates with vegetable oil. Over medium-high heat, grill the red onion, red bell pepper, zucchini, and shiitake mushrooms until charred and tender (about 2–3 minutes per side). Remove and dice. Grill the marinated beef for 1–2 minutes per side until just cooked and caramelized; let cool, then chop into bite-sized pieces. This step infuses smoky, barbecue flavor—key for summer!

Step 4: Prepare the No-Bake Custard

In a large bowl, whisk together eggs, cream, milk, gochujang, Dijon mustard, and salt until smooth. Stir in both cheeses. The gochujang gives your custard a gentle, lingering heat and unmistakable Korean flair.

Step 5: Assemble the Quiche

Scatter grilled vegetables and bulgogi beef evenly over the chilled crust. Pour the custard mixture on top, smoothing the surface. Sprinkle with chives and sesame seeds for color and crunch.

Step 6: Set the Quiche (Chill to Firm)

Cover the pan tightly with plastic wrap and chill in the coldest part of your refrigerator for at least 2 hours, or until the filling is set (it should wobble slightly but hold its shape when sliced). The eggs and cream will gently thicken and set without baking, thanks to the cold and the cheeses.

Step 7: Serve and Enjoy

Carefully unmold the quiche from the pan and peel away the plastic. Slice and serve cold or at cool room temperature—ideal for summer barbecues or picnics! Garnish with extra thyme leaves if desired.

Pro Tips

• Firm Crust: Really compress the panko mixture into the pan—use a flat-bottomed glass for best results. A well-packed crust won’t crumble when sliced.
• Quick Cooling: Place the quiche in the coldest part of your fridge or even the freezer for 20 minutes at the end for a faster, firmer set.
• Flavor Layering: Grilling the vegetables and beef adds smoky, caramelized flavor that’s essential for the barbecue theme.

Troubleshooting

Crust Falls Apart? Try adding an extra 10–15 g melted butter to bind the crumbs, and be sure to chill the crust thoroughly before filling.

Quiche Isn’t Setting? Ensure it chills long enough—overnight is best for a firmer custard. If still too soft, try reducing the milk by 20–30 ml next time.

Variations

• Vegetarian: Skip the bulgogi and add grilled marinated tofu or extra mushrooms.
• Spicier: Increase gochujang to 2 tbsp or add thinly sliced fresh chili.
• Seafood Twist: Swap bulgogi for grilled shrimp marinated in the same sauce for a coastal summer vibe.

Storage

Store leftovers covered in the fridge for up to 3 days. Serve chilled straight from the fridge, or let stand at room temperature for 15 minutes to soften slightly. Not suitable for freezing, as the no-bake custard can weep when thawed.

Enjoy bringing a taste of Korean summer barbecue to your next gathering—no oven required!
