You’ll appreciate how this recipe transforms humble ingredients—frozen broccoli, canned tuna, basic pantry staples—into something truly satisfying. The velvety cheese sauce envelops each piece of broccoli and flaked tuna, creating comfort food magic.

What Ingredients are in Crustless, Broccoli, Tuna Quiche?

This quiche is a representation of simplicity—requiring just a handful of everyday ingredients that transform into something magical when combined.

The beauty lies in its straightforward ingredient list, most of which you probably already have tucked away in your freezer, pantry, or refrigerator. No fancy shopping trips needed for this weeknight wonder. And despite its humble components, the result is a creamy, protein-rich dish that satisfies on multiple levels.

  • 1 package (900g) frozen broccoli
  • 6 tablespoons butter or margarine
  • 1/2 cup all-purpose flour
  • 1 teaspoon salt
  • 3 1/2 cups milk
  • 1/3 cup grated yellow cheese
  • 1 tablespoon lemon juice
  • 1 can tuna, drained and flaked (oil or water-packed, your choice)

When choosing your ingredients, remember that little substitutions can make this recipe your own.

The type of cheese isn’t specified, so feel free to experiment—sharp cheddar adds a nice tang, while something milder like Monterey Jack melts beautifully.

The recipe also works with fresh broccoli if you prefer, though frozen saves precious prep time.

And while the recipe calls for butter or margarine, I find that butter delivers that irreplaceable richness that elevates the final dish from good to can’t-stop-eating good.

Who knew such basic ingredients could create something so comforting?

How to Make This Crustless, Broccoli, Tuna Quiche

Making this quiche is wonderfully straightforward—the kind of cooking that feels therapeutic after a long day. Start by cooking your 900g packet of frozen broccoli in lightly salted water until it’s tender but still has a bit of bite.

Once done, immediately rinse it under cold water (this stops the cooking process and preserves that vibrant green color) and drain thoroughly. Nobody wants a soggy quiche, right? While the broccoli cools, preheat your oven to 350°F, giving it plenty of time to reach the perfect temperature.

Now comes the creamy base that makes this quiche so irresistible. In a medium pot, melt 6 tablespoons of butter over medium heat until it’s just liquid but not browning.

Sprinkle in 1/2 cup of flour, stirring constantly to create a roux—that magical paste that will thicken everything. Keep stirring (no multitasking here, trust me) as you slowly add 3 1/2 cups of milk, watching the mixture transform from paste to silky sauce.

Once it’s nicely thickened, add 1 teaspoon of salt, 1/3 cup of grated yellow cheese, and 1 tablespoon of lemon juice, stirring until everything’s melted together in creamy harmony. The lemon juice might seem strange, but it adds a brightness that balances the richness perfectly.

Off the heat, gently fold in your well-drained broccoli and one can of drained, flaked tuna. This is where the magic happens—the delicate fish, the vibrant broccoli, all suspended in that velvety sauce.

Pour this gorgeous mixture into a glass baking dish (no greasing needed), cover it, and bake for 35 minutes. Then, remove the cover and let it continue baking for another 10-20 minutes until the top is golden and bubbling.

The uncovered baking time is essential—it’s what gives you those slightly crispy edges that contrast so beautifully with the creamy interior. When it’s done, let it rest for about 5 minutes before serving, allowing the flavors to settle and making it easier to portion without falling apart.

Crustless, Broccoli, Tuna Quiche Substitutions and Variations

While the classic recipe creates an amazing dish, let’s talk about how you can personalize this quiche to fit your pantry and preferences.

Don’t have frozen broccoli? Fresh works perfectly—just steam until tender.

Swap tuna for cooked salmon or chicken if seafood isn’t your thing. I’ve used Swiss cheese instead of yellow with fantastic results, and a dash of dill takes the flavor profile in a whole new direction.

For a richer version, try half-and-half instead of milk.

And those avoiding gluten? Replace flour with cornstarch (about half the amount).

Sometimes I add sautéed mushrooms when I’m feeling fancy.

What to Serve with Crustless, Broccoli, Tuna Quiche

A perfectly baked crustless broccoli tuna quiche deserves thoughtful accompaniments that complement its savory, protein-rich profile without overwhelming it.

I love pairing mine with a crisp green salad dressed simply in lemon vinaigrette—the acidity cuts through the richness beautifully.

For a heartier meal, roasted cherry tomatoes or sautéed mushrooms make wonderful sides.

Can’t decide? Go for both!

A chilled cucumber soup works wonderfully in summer, while warm crusty bread is my go-to during cooler months.

Wine lovers, reach for a light Sauvignon Blanc or unoaked Chardonnay.

The citrus notes? Absolute perfection with the lemon and tuna flavors.

Final Thoughts

This crustless broccoli tuna quiche has become my reliable kitchen companion over the years, ready to show up whenever I need a protein-packed meal without the fuss.

I’ve made it for last-minute dinner guests, prepped it for busy weeknights, and even served it cold for picnics.

What I love most is its versatility—swap salmon for tuna, add different cheeses, or toss in those lonely vegetables hiding in your crisper drawer.

The recipe forgives minor adjustments and still delivers that comforting, savory goodness every time.

Trust me, once you try it, you’ll wonder where this simple dish has been all your life.
