Light Zucchini & Tuna Quiche (Crustless)
There’s something incredibly comforting about a warm, savory slice of quiche fresh out of the oven. And when that quiche is light, protein-packed, and crustless? You’ve got a weeknight hero that feels indulgent but leaves you feeling great. This Light Zucchini & Tuna Quiche is creamy, fluffy, and brimming with flavor from fresh herbs, tender zucchini, and flaky tuna. It’s a dish that surprises you with how simple and satisfying it can be.
Behind the Recipe
This quiche recipe was born on one of those “what’s-in-the-fridge” evenings. You know the ones—zucchini on the edge, a can of tuna in the pantry, and eggs always on hand. But with a bit of seasoning and a hot oven, magic happened. What started as an improvised dinner quickly became a family favorite, showing up on brunch tables and light dinners alike. There’s a nostalgic charm to it, reminding me of summer meals with windows open and fresh herbs from the garden tossed into everything.
Recipe Origin or Trivia
While quiche might sound like a classic French invention (and it is), the crustless version has taken on a modern twist for those looking to reduce carbs or lighten up traditional dishes. The idea of combining tuna and zucchini isn’t new in Mediterranean kitchens—both ingredients are staples in warm-weather cuisine where simplicity meets nutrition. This particular version leans into that tradition with a healthier edge, skipping the pastry but not the flavor.

Chef’s Pro Tips for Perfect Results
If you want that perfect texture and flavor, here are a few tricks I’ve picked up:
- Squeeze the zucchini: After grating, salt and squeeze out as much moisture as possible to avoid a soggy quiche.
- Use room temperature eggs: They whisk more evenly and help the quiche puff up beautifully.
- Don’t overmix: Gently fold ingredients to keep the texture light and airy.
- Rest before slicing: Let it sit for 10 minutes after baking so it holds its shape.
- Add fresh herbs last: This keeps their flavor bright and fresh.
