This zucchini egg bake is the kind of dish that looks like you spent way more time on it than you actually did. Fluffy eggs, melty cheese, bits of savory mortadella, and tender zucchini all baked into one golden, sliceable beauty.
I first made this on a Sunday when my fridge was basically a zucchini graveyard. Thirty minutes later, my family was fighting over the last square. It has been a weekly staple ever since.

How to Make Zucchini Egg Bake Step by Step
Don’t let the short ingredient list fool you — there’s technique in here that makes a real difference. Follow these steps and your egg zucchini bake will come out perfectly every single time.
Step 1: Preheat the Oven
Set your oven to 400F (200C). Let it fully preheat while you prep everything else. A hot oven from the start is what gives you those gorgeous golden edges.
Step 2: Mix the Egg Base
Crack all 8 eggs into a large bowl. Add the cottage cheese and a pinch of salt, then mix until everything is smooth and combined.
Don’t rush this step. You want the cottage cheese broken up and evenly distributed so it melts into the eggs during baking. Think of it as your secret weapon for a custardy texture.
Step 3: Squeeze Out the Zucchini Moisture
This is the most important step in any egg bake with zucchini recipe. Grab the grated zucchini and transfer it to a cheesecloth, a clean kitchen towel, or just use your clean hands.
Squeeze firmly and get out as much liquid as possible. Skipping this step means a watery bake that won’t hold its shape. Squeeze, squeeze, and squeeze again.
According to The Kitchn’s guide to squeezing zucchini, removing excess moisture is the single biggest factor in getting a firm, sliceable result rather than a soggy one.
Step 4: Build the Batter
Add the squeezed zucchini to the egg mixture. Toss in the diced mortadella and grated Kashkaval cheese. Then add the flour and baking powder.
Mix everything together until well combined. The baking powder gives the bake a slight lift, making it less dense and more satisfying to eat. The flour helps bind it all together.
Step 5: Bake Until Golden
Line a baking dish with parchment paper — this saves you from a cleanup disaster. Pour in the egg mixture and spread it evenly.
Bake at 400F for 25 to 30 minutes, until the top is golden brown and a toothpick inserted in the center comes out clean. Your kitchen will smell absolutely incredible at around the 20-minute mark.
Let it rest for 5 minutes before slicing. This helps the bake firm up so you get clean, neat squares instead of a scrambled mess.
Expert Tips for the Best Egg and Zucchini Bake
Squeeze the Zucchini Really Well
I know I already said this, but it deserves repeating. Excess moisture is the enemy of a good egg zucchini bake. Squeeze until your hands are tired. Your future self will thank you.
Use a Cheese That Melts Well
Kashkaval is a slightly salty, buttery cheese that melts beautifully. If you can’t find it, try mozzarella, provolone, or a mild cheddar. Avoid crumbly cheeses like feta for this one — they don’t melt the same way.
Don’t Skip the Baking Powder
It might seem like a strange addition to an egg dish, but baking powder is what lifts this from a flat frittata into something with real body. It keeps the interior light and fluffy rather than dense and rubbery.
Customize the Protein
No mortadella? No problem. Ham, turkey, cooked bacon, or even leftover chicken from a sandwich recipe all work beautifully here. You can also go meat-free by adding sundried tomatoes or roasted red peppers instead.
Variations to Try
Make It Gluten-Free
Swap the all-purpose flour for oat flour. It works just as well as a binder and keeps the bake light. This is a great option if you’re cooking for a gluten-sensitive crowd.
Add More Vegetables
Diced bell pepper, spinach, grated carrot, or thinly sliced mushrooms all work great in this baked eggs with zucchini recipe. Just make sure any extra veggies are well-drained before adding them to the batter.
Go Dairy-Free
Skip the cottage cheese and use a dairy-free yogurt or a splash of unsweetened oat milk instead. Use a plant-based shredded cheese in place of the Kashkaval. For a great dairy-free butter option to grease the pan, check out this Miyoko’s oat butter recipe.
Spice It Up
Add a pinch of smoked paprika, a dash of garlic powder, or some chili flakes to the egg mixture. A little heat goes a long way and makes the whole thing pop with flavor.
Troubleshooting Common Problems
My Bake Is Watery
This always comes back to the zucchini. You didn’t squeeze enough moisture out. Next time, really wring that zucchini dry. You can also salt the grated zucchini and let it sit for 10 minutes before squeezing — it draws out even more water.
The Center Is Still Jiggly
Give it more time. Every oven is a little different. If the top is getting too brown but the center is still soft, cover loosely with foil and bake for another 5 to 10 minutes.
It’s Sticking to the Pan
Always use parchment paper. A light spray of cooking oil under the parchment also helps. The Miyoko butter recipe is a great dairy-free option to grease the dish if you’re skipping parchment.
Storage Instructions
| Storage Method | How to Store | How Long |
|---|---|---|
| Refrigerator | Store in an airtight container or wrap the dish tightly | Up to 4 days |
| Freezer | Wrap individual slices in plastic wrap and place in a freezer bag | Up to 2 months |
| Meal Prep | Slice into portions and refrigerate for grab-and-go breakfasts | Up to 4 days |
How to Reheat
For the best texture, reheat slices in the oven at 350F for about 8 minutes. The microwave works too — just 60 to 90 seconds on medium power. Avoid high heat, which can make the eggs rubbery.
No-Waste Kitchen Ideas
Got extra grated zucchini? Freeze it in half-cup portions for next time. Leftover baked squares make a killer sandwich filling with a smear of mustard and some greens. You can also crumble leftover slices into a salad for a protein boost.
Frequently Asked Questions
Can I make this zucchini egg bake ahead of time?
Yes, absolutely. You can assemble the mixture the night before and keep it covered in the fridge, then bake it fresh in the morning. Alternatively, bake it fully and reheat slices throughout the week. It actually tastes even better the next day once the flavors have settled.
Can I freeze the egg bake with zucchini?
Yes, this egg and zucchini bake freezes well. Let it cool completely, slice into individual portions, wrap each slice tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat in the oven for best results.
What can I use instead of mortadella?
Any deli meat works here. Try diced ham, turkey, cooked crumbled sausage, or even smoked salmon. For a vegetarian version, skip the meat and add sun-dried tomatoes, roasted peppers, or sliced olives for a savory punch.
Why does my egg zucchini bake turn out watery?
The culprit is almost always the zucchini. Grated zucchini holds a surprising amount of water. Be sure to squeeze it really firmly in a cheesecloth or kitchen towel before adding it to the batter. For extra insurance, salt the zucchini first and let it sit for 10 minutes before squeezing.
Is this recipe gluten-free?
It can be. Simply swap the all-purpose flour for oat flour or any certified gluten-free flour blend. The rest of the ingredients are naturally gluten-free, so the substitution is easy and the texture stays just as good.
