Honestly, this Baked Zucchini, Spinach & Feta Casserole recipe crept into my life during a summer when my garden was, shall we say, overachieving with zucchini. I was drowning in green squash, and my usual go-to zucchini bread just wasn't cutting it anymore. I remember staring at a mountain of zucchini on my counter, feeling a bit defeated, when an old Greek cookbook (a hand-me-down from my yiayia, bless her soul) fell open to a page with a faded picture of something cheesy and green. The aroma of garlic and feta, even just imagined, suddenly filled my kitchen. It felt like a sign, a delicious, cheesy, comforting sign. This dish became my answer, my salvation, and honestly, a hug in casserole form. It’s so much more than just a vegetable bake, it’s a taste of summer, a memory of family, and a simple solution to a very full garden.
I remember the first time I made this Baked zucchini, Spinach & Feta Casserole. I was so excited, but also a bit distracted by a rogue cat trying to scale the curtains. In my haste, I completely forgot to squeeze the water out of the zucchini. Oops! The casserole came out a little… soupy. Still delicious, but definitely not the firm, sliceable dream I was going for. It was a good laugh, and a lesson learned the hard way: patience with your veggies pays off. Now, I always make sure to give those greens a good squeeze!
Ingredients for Baked Zucchini, Spinach & Feta Casserole
- Fresh Zucchini: This is our star, right? Don't skimp on fresh, firm zucchini. It brings such a lovely, mild sweetness and a tender bite. I usually grab medium ones, the giant ones can be a bit watery and seedy, which we don't want.
- Fresh Spinach: Bags of baby spinach are my go-to. It wilts down to almost nothing, so grab more than you think you need! I tried frozen once, and it worked... kinda. Just make sure to really, really squeeze out all that extra water, or your casserole will be swimming.
- Crumbled Feta Cheese: Oh, the salty, tangy hero! This is what gives our Baked Zucchini, Spinach & Feta Casserole its amazing Mediterranean vibe. I always go for a good quality block of feta and crumble it myself, it just tastes fresher than pre-crumbled, honestly.
- Large Eggs: These are the binding magic, holding everything together in a beautiful, creamy custard. I've definitely cracked a shell or two into the bowl in my time, just fish it out, no biggie!
- Milk (Whole or 2%): For that rich, creamy base. Don't use skim milk, just don't. The fat content here is key for a luscious texture. I usually have 2% on hand, and it works perfectly.
- All-Purpose Flour: Just a touch to thicken our custard and ensure a sturdy, sliceable casserole. It helps absorb some of that zucchini moisture too.
- Garlic Cloves: Fresh is best, always. I usually add an extra clove or two beyond what a recipe calls for because, well, I'm a garlic fiend. It just makes everything better, you know?
- Fresh Dill: This herb is non-negotiable for me in this dish. It adds such a bright, herbaceous note that sings with the feta and spinach. Dried just isn't the same, trust me.
- Ground Nutmeg: A tiny pinch makes a huge difference, adding a warm, subtle depth to the creamy sauce. It's one of those secret ingredients that elevates the whole dish.
- Black Pepper & Salt: Seasoning is everything! A generous grind of fresh black pepper and salt to taste. Remember feta is salty, so taste before adding too much extra salt.
- Olive Oil: For sautéing and greasing the dish. A good quality extra virgin olive oil adds a lovely base flavor.
How to Make Baked Zucchini, Spinach & Feta Casserole
- Prep Your Zucchini & Spinach:
- First things first, get those veggies ready! Grate your zucchini (I usually use the large holes on a box grater) and then, this is crucial, squeeze out as much water as you possibly can. I use a clean kitchen towel for this wrap it up and twist, twist, twist! You’ll be amazed how much liquid comes out. Then, wilt your spinach. You can do this quickly in a hot pan with a splash of olive oil, or even just pour boiling water over it and then drain. Again, squeeze, squeeze, squeeze! This step prevents a soggy Baked Zucchini, Spinach & Feta Casserole, and honestly, I learned that the hard way. Don't skip it!
- Whip Up the Creamy Base:
- In a large bowl, whisk together your eggs, milk, and flour until it's super smooth. No lumps allowed! This mixture is going to create that lovely, custardy texture that binds everything together. Then, stir in your minced garlic, fresh dill, a generous pinch of nutmeg, and a good amount of black pepper. Remember the feta is salty, so go easy on adding extra salt at this stage. This is where the magic starts to happen, the aroma of the dill and garlic always gets me excited! I once forgot the nutmeg and the casserole just wasn't quite as warm and comforting. Little details matter!
- Combine & Layer the Casserole:
- Now for the fun part: bringing it all together! Gently fold your well-drained zucchini and spinach into the creamy egg mixture. Add about two-thirds of your crumbled feta cheese here, mixing it in so it’s distributed throughout. Take a moment to really combine everything, ensuring every bit of vegetable is coated in that delicious custard. Pour this mixture into a lightly greased 9x13 inch baking dish. Smooth out the top. This step is pretty forgiving, but a good even layer ensures even baking for our Baked Zucchini, Spinach & Feta Casserole.
- Bake Until Golden:
- Sprinkle the remaining feta cheese over the top of the casserole. If you're feeling fancy (and I often am!), a little sprinkle of grated Parmesan cheese adds a lovely golden crust. Pop it into a preheated oven at 375°F (190°C) and bake for about 35-40 minutes. You’re looking for a beautiful golden-brown top and a set center. When I peek through the oven door and see that bubbling, golden goodness, I know dinner is going to be a winner. My kitchen usually smells incredible at this point, like a cozy Greek taverna!
- Let It Rest (Crucial!):
- This is perhaps the hardest step, honestly. Once your Baked Zucchini, Spinach & Feta Casserole comes out of the oven, it's going to be tempting to dig right in. But resist! Let it rest on a wire rack for at least 10-15 minutes. This allows the custard to fully set and makes for much cleaner slices. If you cut into it too soon, it might be a bit loose, and nobody wants a messy casserole. I've made that mistake more times than I care to admit, eager for that first bite!
- Serve Your Baked Zucchini, Spinach & Feta Casserole:
- Once it's had its beauty rest, slice into generous portions. I love how the vibrant green of the spinach and the white of the feta peek through the golden crust. Serve it warm, perhaps with a simple side salad or some crusty bread to sop up any delicious juices. It’s incredibly satisfying, and honestly, the flavors just deepen as it cools slightly. A perfect end to a busy day, or a delightful start to a weekend brunch. Enjoy every single bite of this amazing Baked Zucchini, Spinach & Feta Casserole!

For the spinach, kale or Swiss chard can work if you blanch and chop them well, making sure to squeeze out all the water. No fresh dill? Dried dill is okay in a pinch, but use about a third of the amount. You could also try fresh parsley or a mix of Mediterranean herbs.
