Hey there, friend! Let’s be real for a second: mornings can be… a lot. The alarm blares, the to-do list looms, and before you know it, you’re staring into the abyss of the fridge, wondering how a bag of shredded cheese and a half-empty jar of pickles constitutes a balanced breakfast.

So, take a deep breath, grab your favorite mixing bowl, and let’s cook up a solution to your morning madness, together.

A Tale of Two Fishermen and One Brilliant Breakfast

Print

This recipe has a special place in my heart, and it all goes back to my grandfather. Every summer, he’d wake up at an ungodly hour, pack a cooler of questionable sandwiches, and head out on his little boat, returning hours later with a sunburn and (if we were lucky) a few beautiful fresh-caught trout. The problem? He was a fantastic fisherman but a, well, enthusiastic one. We’d often find ourselves with more fish than we could possibly eat in one sitting.

My grandma, the queen of kitchen resourcefulness, never let anything go to waste. I’ll never forget the morning after a particularly successful fishing trip, watching her flake leftover grilled trout into a bowl of eggs with some chopped scallions from her garden. She poured it into a cast-iron skillet, and the most incredible aroma filled the kitchen. That simple, crustless creation was my first introduction to the magic of turning yesterday’s dinner into today’s stellar breakfast. This tuna quiche is my nod to her—a way to capture that same spirit of making something wonderfully delicious out of simple, humble ingredients. Using canned tuna is just our modern, super-convenient shortcut to that same feeling of cozy, seaside satisfaction.

Your Cast of Kitchen Characters

Here’s everything you’ll need to bring this protein-packed wonder to life. Don’t be shy about making swaps—cooking is about playing with your food!

• 6 large eggs: Our superstar binder and the fluffy foundation of our quiche. They provide high-quality protein to keep you full and focused all morning. For a richer, custard-like texture, you can swap one or two for a splash of milk or cream, but it’s wonderfully hearty without!
• 1 can (5–6 oz) tuna, drained: I prefer solid white albacore in water for its mild flavor and firm texture, but chunk light works perfectly too! This is our secret protein weapon, making this quiche incredibly satisfying. Chef’s Insight: Give the tuna a good squeeze in a fine-mesh strainer or with a paper towel to remove excess liquid. This prevents a soggy quiche!
• 1 medium zucchini, grated and squeezed dry: This little green gem adds moisture, vitamins, and a lovely lightness. The key step here is squeezing it dry! After grating, pile it into a clean kitchen towel or a few paper towels and wring out every last drop of water. You’ll be amazed at how much comes out!
• 1 small carrot, grated (optional for low-carb): A pop of color and a touch of natural sweetness. It blends right in, making it a great way to sneak extra veggies onto any plate. Feel free to omit for a stricter low-carb version.
• ½ small onion, finely chopped: The aromatic base note that builds so much flavor. Yellow, white, or a couple of shallots all work beautifully here.
• ¼ cup rolled oats (optional—adds texture): This is my little hack for adding a subtle, wholesome heartiness that helps bind everything together. They soften during baking and you’d never know they’re there! Omit for grain-free, or substitute with 2 tablespoons of almond flour.
• ½ tsp dried dill & ½ tsp dried basil: Our herby dream team! Dill and tuna are a match made in heaven, offering a bright, almost lemony freshness, while basil brings a warm, cozy depth. If you have fresh herbs, use 1 ½ teaspoons of each, finely chopped.
• ½ tsp black pepper & Salt, to taste: The essential flavor enhancers. I start with ¼ teaspoon of salt and adjust from there, as the tuna can vary in saltiness.
• Optional: shredded cheese or chopped parsley for topping: A sprinkle of sharp cheddar, melty mozzarella, or tangy feta on top before baking creates a gorgeous, golden crust. A fresh sprinkle of parsley after baking adds a burst of color and freshness.

Let’s Build Your Breakfast Masterpiece

Ready to see how easily this all comes together? Follow these steps, and you’ll have a kitchen filled with the most incredible smell in no time.

1. Preheat and Prep. Fire up your oven to 375°F (190°C). While it’s warming up, grab an 8×8 baking dish or a standard 12-cup muffin tin and give it a good coat of non-stick spray, or line it with parchment paper for absolutely zero stick. Chef’s Hack: If you’re using a muffin tin, those little silicone liners are a game-changer for easy pop-out-every-time results!
2. Whisk Your Foundation. Crack your 6 eggs into a large mixing bowl. Now, channel your inner kitchen maestro and whisk them with enthusiasm until they’re smooth and pale yellow. This incorporates air, which leads to a fluffier bake! Whisk in your dried dill, basil, black pepper, and salt.
3. The Big Mix-In. Time to bring the band together! Add your thoroughly drained tuna, the squeezed-dry grated zucchini, the grated carrot, chopped onion, and the optional rolled oats to the egg bowl. Grab a sturdy spatula and fold everything together until it’s one happy, well-combined mixture. Little Tip: I like to flake the tuna in with a fork first to break up any big chunks before I start folding.
4. Pour and (Optionally) Top. Carefully pour your quiche mixture into your prepared baking dish, or use a measuring cup to neatly fill each muffin cup about ¾ of the way full. If you’re using cheese, now’s the time for a generous sprinkle over the top. It’ll bake into a gorgeous, cheesy crust.
5. Bake to Golden Perfection. Slide your creation into the preheated oven. For a single large quiche in an 8×8 dish, bake for 25-30 minutes. For muffin-sized mini quiches, start checking at 20-22 minutes. You’ll know it’s done when the top is beautifully golden, the edges are just starting to pull away from the pan, and the center is set (no jiggle when you give the pan a gentle shake).
6. The Most Important Step: Cool! I know, the aroma is intoxicating and you want to dive right in! But patience, my friend. Let the quiche cool in the pan for at least 5-10 minutes. This allows the proteins to set fully, making it MUCH easier to slice or remove from the muffin tin without falling apart.

Plating Up Your Perfect Morning

How you serve this is half the fun! For a cozy, at-home breakfast, slide a warm square onto a plate alongside a handful of fresh arugula salad with a quick squeeze of lemon. Heading out the door? Let the muffin-sized versions cool completely, then toss one or two into a container for the ultimate grab-and-go power breakfast. On the weekends, turn it into a brunch star by serving it with a side of roasted cherry tomatoes and a slice of whole-grain toast. However you dish it up, it’s a win.

Make It Your Own! 5 Delicious Twists

This recipe is a fantastic canvas for your cravings. Here are a few of my favorite ways to mix it up:

• The Mediterranean: Swap the tuna for a can of crumbled feta cheese and add a handful of chopped sun-dried tomatoes and kalamata olives. Use oregano instead of dill.
• The Everything Bagel: Skip the dill and basil and stir in 2 tablespoons of everything bagel seasoning into the egg mixture. Top with everything seasoning and sesame seeds before baking.
• Spicy Southwest: Use a can of chili-lime tuna or add a diced jalapeño and ½ teaspoon of cumin. Stir in ¼ cup of corn (if not strict low-carb) and top with a mix of cheddar and Monterey Jack cheese.
• Dairy-Free Delight: It’s already naturally dairy-free without the cheese topping! For extra creaminess, add a splash of unsweetened almond milk to the eggs.
• Pescatarian Power-Up: Replace the tuna with a can of well-drained, flaked salmon for a different flavor profile that’s equally delicious and packed with omega-3s.

From My Kitchen to Yours: A Few Final Thoughts

This quiche has truly evolved into a family staple. I’ve made it for new parents needing an easy freezer meal, for my kids’ hectic school mornings, and for lazy Sunday brunches with friends. The funny thing is, my husband, who claimed to “not really like tuna,” devoured two helpings the first time I made it and now requests it weekly. The magic is in the way the other flavors meld together—you get the protein and heartiness of the tuna without it being the one overwhelming star.

My biggest piece of advice? Don’t skip the step of squeezing the zucchini. I learned that the hard way early on with a slightly weepy quiche that was still delicious, but not quite as perfect. This little quiche is a testament to my grandma’s philosophy: great food is about joy, nourishment, and a little bit of cleverness, not about complicated techniques or fancy ingredients. I hope it brings as much ease and happiness to your kitchen as it has to mine.

Your Quiche Questions, Answered!

Let’s tackle a few common questions to make sure you’re feeling 100% confident.

Q: Can I make this ahead of time and how do I store it?
A: Absolutely! This is a meal-prep champion. Once cooled, store it in an airtight container in the fridge for up to 4 days. You can reheat individual slices in the microwave for 30-60 seconds or in a 350°F oven for about 10 minutes until warm. You can also freeze it for up to 3 months. I recommend slicing it first and wrapping individual portions for easy thawing.

Q: My quiche turned out a bit watery. What happened?
A: The most common culprit is moisture from the vegetables, specifically the zucchini. Next time, be extra vigilant about squeezing it as dry as humanly possible. Another tip is to make sure your tuna is thoroughly drained. A little patience in the prep stage prevents sogginess in the final product!

Q: I don’t have a muffin tin. Can I still make this?
A: Of course! An 8×8 square baking dish or a 9-inch pie plate works beautifully. Just note that the baking time will be a bit longer (closer to 25-30 minutes). The key is to bake until the center is completely set.

Q: Can I use fresh spinach instead of zucchini?
A: You sure can! I’d recommend using about 1 to 1.5 cups of finely chopped fresh spinach. And just like with the zucchini, you’ll want to wilt it slightly and squeeze out any excess liquid before adding it to the mix. Sauté it for a minute or two until wilted, let it cool, then give it a good squeeze in a towel.

Nourish Your Body & Soul
