This crustless tuna and tomato quiche is a tasty and quick dish to prepare, ideal for a light meal or a picnic. Its soft texture and delicious flavor make it a real treat for the taste buds.

 

Step-by-Step Instructions

Step 1: Prepare the Ingredients

Preheat your oven to 180°C (350°F) and position a rack in the center. Lightly grease a pie dish or quiche dish (about 22-24 cm / 9 inches in diameter) with a little butter or oil to prevent sticking. Drain the canned tuna thoroughly, pressing out as much liquid as possible with a fork or by squeezing it in a clean kitchen towel. This step is essential—too much moisture will make the quiche watery. Wash the tomatoes and slice them into rounds about ½ cm (¼ inch) thick, or dice them if you prefer smaller pieces throughout the quiche.

Step 2: Make the Egg Custard

In a large mixing bowl, whisk together the eggs, heavy cream, and Dijon mustard until smooth and fully combined. The mustard helps emulsify the mixture and adds a subtle, tangy depth that balances the richness of the cream and cheese. Season with salt, pepper, and your chosen herbs (herbes de Provence or fresh basil). Stir in the grated cheese, reserving a small handful for sprinkling on top. Add the well-drained tuna and mix gently to distribute it evenly throughout the custard.

Step 3: Assemble the Quiche

Pour the egg mixture into the prepared pie dish, spreading it evenly with a spatula. Arrange the tomato slices on top in a single, overlapping layer—this creates a beautiful, rustic presentation and ensures every bite has a burst of juicy tomato flavor. Sprinkle the reserved grated cheese over the tomatoes for a golden, bubbly crust. If using fresh basil, you can add a few torn leaves on top before baking or save them for garnish after.

Step 4: Bake and Rest

Place the quiche in the preheated oven and bake for 30 to 35 minutes, until the center is set and the top is beautifully golden and puffed. The quiche should have a slight jiggle in the center when you gently shake the dish—it will continue to set as it cools. Remove from the oven and let it rest for 5 minutes before slicing. This resting period allows the custard to firm up, making the quiche easier to cut and serve without falling apart.

Tips for Success

• • Drain the tuna thoroughly: Excess liquid from the tuna can make the quiche watery. Press it well with a fork or wrap it in a clean kitchen towel and squeeze.

• • Use ripe but firm tomatoes: Overly ripe tomatoes release too much juice during baking, which can affect the texture. If your tomatoes are very juicy, you can lightly salt them and let them sit on paper towels for a few minutes to draw out excess moisture.

• • Don’t overbake: The quiche is done when the center is just set and still slightly wobbly. Overbaking will make it dry and rubbery.

• • Let it rest: Allowing the quiche to rest for 5 minutes before serving helps it set and makes slicing much easier.

Variations and Substitutions

• • Vegetable version: Replace the tuna with sautéed mushrooms, spinach, or roasted bell peppers for a vegetarian alternative.

• • Smoked fish option: Swap the canned tuna for smoked salmon or canned salmon for a different flavor profile.

• • Cheese choices: Experiment with different cheeses like feta, goat cheese, or Parmesan for varied flavor and texture.

• • Herb variations: Replace herbes de Provence with fresh oregano, thyme, or chives for a different aromatic touch.

• • Dairy-free: Use a plant-based cream alternative and dairy-free cheese to make this recipe suitable for lactose-intolerant guests.

How to Serve

This crustless quiche is wonderfully versatile and can be served warm, at room temperature, or even cold. It’s delicious on its own, but pairs beautifully with a crisp green salad dressed with a light vinaigrette for a complete, balanced meal. It also makes a fantastic addition to a picnic basket, a brunch spread, or a light dinner accompanied by roasted vegetables or a slice of crusty bread.

Storage and Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place individual slices in the microwave or return the quiche to the oven at 160°C (325°F) for 10 to 12 minutes until warmed through. This quiche is also delicious cold, making it a great option for packed lunches or on-the-go meals.

Frequently Asked Questions

Can I use fresh tuna instead of canned? Yes, you can use fresh cooked tuna. Simply pan-sear or poach a fresh tuna steak, flake it, and use it in place of the canned tuna. Cooked salmon or chicken also work well. Can I make this quiche ahead of time? Absolutely. You can prepare the quiche the day before, store it in the refrigerator, and serve it cold or reheat it gently before serving. What type of cheese works best? Gruyère and Emmental are classic choices for their excellent melting properties and nutty flavor. Cheddar adds a sharper taste, while Parmesan brings a salty, savory note. How do I prevent the quiche from sticking to the dish? Generously grease the pie dish with butter or oil, or line it with parchment paper for easy removal.
