Is zucchini low-carb?
Yes, zucchini is low-carb, especially if you monitor your daily carb limit and count your macros.
Zucchini nutritional value per 100g/3.5oz is 3.1 g total carbs - 1 g fiber = 2.1 g net carbohydrates. You use a mere 17 calories, 1.2 g of protein, and a whopping 29% of your daily vitamin C needs. Not bad for a medium zucchini!

What is an egg casserole (or quiche)?
A crustless quiche may also be known as a frittata or an egg casserole. It is often a combination of whisked eggs, leftover low-carb vegetables, meat such as ham or bacon, and topped with a shredded cheese crust.
A traditional quiche recipe would require wheat flour, or all-purpose flour, pastry base. Some recipes even add flour or cornstarch to the eggs mixture to make it heavy and dense.
Zucchini, cheese, and bacon quiche was a staple growing up in my family, but my new recipe is flourless and low carb. It is superb for dinners, lunches, and picnics. It's great for packing healthy school lunch boxes and the perfect make-ahead keto breakfast.
Easy low-carb keto meal plans
Using eggs as your main dish with leftover vegetables and meat is an easy addition to your weekly meal plan to stretch out your budget and make low-carb affordable.
When zucchini/courgettes are in season and going cheap, make a huge batch, and it will last a few days. It is a great recipe to fill your freezer. Just cut the keto egg casserole into individual slices when cold, wrap in baking parchment paper, and store in an airtight container.
Ingredients
All quantities, ingredients, and instructions are in the recipe card below.
Low carb zucchini and bacon slice is an adaptable recipe, simply throw in whatever vegetables or leftover meat you have in the fridge. Try different variations by adding a variety of cheeses, herbs, or cherry tomatoes on top.
Basic keto egg casserole: only requires 4 ingredients, then you can vary the fillings
- Eggs - medium
- Milk or heavy cream - may be omitted if you wish to reduce carbs and increase protein.
- Cream cheese - use full fat, not the low fat, lite, or spreadable variety. These lower fat cheeses will not bake properly in the keto quiche and will create a quiche that is often too soft to slice.
- Grated/shredded cheese - added to the top of the crustless quiche and baked to create a crispy cheesy crust.
Variations:
- Bacon - streaky smoked bacon is the most delciioius to use, however you can use ham, crumbled pork sausage, salmon, or leftover meat such as chicken or turkey.
- Spring onion - sliced.
- Zucchini/courgettes - diced.
- Herbs - rosemary, chili flakes, garlic powder, onion flakes.
- Salt/pepper - season to taste.
Step by step guide
Making a keto egg casserole recipe is extremely quick so begin by preheating your oven and then getting all your ingredients together.
You will need eggs, milk, zucchini/courgettes, spring onion, bacon and full-fat block of cream cheese.
Add the eggs to the bowl with the cream cheese, add the milk, whisk together (you can use heavy cream if you wish).
Dice/chop the zucchini/courgettes into little pieces.
Dice the bacon (or other meat of choice). It can be added raw or cooked. The raw bacon will cook in the low-carb zucchini slice.
Mix everything together.
Pour all the ingredients into an oiled and lined baking dish. Cover with plenty of grated/shredded cheese of choice.
Side dishes
You can either serve this crustless quiche (keto egg casserole) as the main meal or as a side dish. I like to serve mine with a leafy green salad, coleslaw, or in winter, with mashed cauliflower for a hearty and comforting dinner.

How easy was that? This really has to be the simplest low-carb zucchini and bacon quiche recipe the whole family will love. It's also flourless, grain-free, gluten-free and made with simple whole food ingredients.
So why not throw some zucchini seeds in the ground this summer and see if you can grow a bumper crop to keep making the zucchini slice? If not, find a friend whose garden is overrun with zucchini and ask them for some fresh zucchini in return for some baked low carb quiche.
Nadia Baker
this looks so good. thankyou I have no cream cheese. I think I'll use mozzarella and cheddar. looking forward to making tonight.
Bianca
Ok so it makes 8. Is 1, 1 serving or is 8? It's 4.9g carbs for how many servings sorry?
Libby www.ditchthecarbs.com
It makes 8 servings, nutrition is per 1 serving.
Fouzia
I just made this. Turned out delicious. I didnβt had the bacon but sprinkled some paprika into the mixture.
Tracy
What is the serving suggestion?
Libby www.ditchthecarbs.com
I usually serve these with a salad and plenty of mayonnaise for a meal, alone for a snack, or wrapped up in lunch boxes.
Miss zee
Hi, do you think mayonnaise will work as a good substitute for the cream cheese in this recipe? I always substitute mayo for cream cheese for my cloud bread, It turns out really good and I find it tastes nicer too.
Marisa
What brand of bacon do you use it looks delicious and on the meaty vs. fatty side
Libby www.ditchthecarbs.com
I use Henderson's bacon here in NZ. Nice and chunky without all the nasties.
Denise Farr
Excellent recipe. I added a diced onion cooked gently with 1 tsp curry powder [using a previous comments idea], and baked it longer [40 minutes]. I think I will cut the cream cheese into little cubes next time to ensure there are lots of delicious little lumps throughout the recipe. I would really love more vegetable and savoury recipes like this. The sweet recipes you have are great, but I really want to keep away from eating sweet food the majority of the time, so a variety of vegetable and meat recipes are really appreciated, thanks.
Darren
How big of a baking dish ? And lined as in parchment ? Sorry I'm a bit of a wimp when it comes to winging it haha.
Denise Farr
I used a ceramic baking dish 30cm x 25cm, and I greased it with coconut oil instead of using parchment / baking paper and it came out fine with a fish slice type utensil. The slice was about 2cm deep.
Margaret Parry
Just made it delicious - will make it regularly for sure. I also found it took longer to cook but I am a bit heavy handed on ingredients - but who cares it was yummy!
sewingnz
This has become a staple lunch for me. I grate my zucchini instead of leaving it chunky. Also added fresh mint this week which was outstanding. Thanks for another great recipe.
Jelly
I sauteed the bacon, spring onions and zuchini first in ex vir olive oil as I like them slightly browned before they go in the oven. Had no cream cheese so used ricotta.Used up some mozzarella.It was delicious. Would be nice with other veges and a some salmon next time.
Deniseregina
Please...when you say 4 zucchini, can you please give amount in volume? 2 cups? 4 cups? Right now, I have a bunch of little ones from my CSA. Towards the end of summer, my garden will produce ones I could hit a home run with, if I don't catch them in time!?
I request this of many sites. "A medium onion", "one large pepper", etc. Makes it a whole lot easier. Thanks
Deniseregina
RWebb
Any recommendations on cheese types?
Libby www.ditchthecarbs.com
I just use cheese such as Edam, Colby, Mild or Cheddar.
RWebb
I made it yesterday with Colby and it came out great! I did forget to pick up some onion so next time it will be even better π
Noelle
This may be a silly question, but do you cook the bacon first in this recipe?
Libby www.ditchthecarbs.com
Great question, no it goes in raw and cooks whilst the zucchini and egg bakes - easy huh?
goingroundandround
Great, thanks!
VONZY
I sauteed shallots with bacon first n was very good
Melodie Carleton
What is 1 streaky smoked bacon rasher in Canadian ? ??
Libby www.ditchthecarbs.com
A bacon rasher = slice of bacon (I must go through and add this to all my recipes, it is the Kiwi/British in me).
Diana
Not sure what the deal is, but for some reason, my slice took way longer to cook than the cook time listed here. It took about 35 minutes for it to be cooked through in the middle.
Noelene
I fry onions, bacon and curry powder and add to the egg mix for extra flavour.
cherrie stevens
Ooooo curry powder, good idea as I'm veggie and so no bacon.... been making this for years as I got the recipe when I lived in NZ.... I also found it takes about 45 mins to cook right through and have golden slightly crispy edges.
Karina
Love the look of this recipe but I'm dairy free. Any suggested replacements for the cream cheese? I could use nut milk for the dairy milk.
Libby www.ditchthecarbs.com
You could actually get rid of all the dairy, the milk just dilutes the eggs so is lighter and the cream cheese adds some extra good fat. It would turn out a bit heavier but give it a go and let me know π
Nicky Gray
Please help!! I am giving the banting diet a go, but am allergic to egg. What can i substitute the egg with?
Libby www.ditchthecarbs.com
This recipe as it is so heavily based on eggs, there is no replacement really, some recipes you can use chia seeds or ground flaxseeds but this mainly applies to baking.
Wendy
I made this tonight but instead of bacon I used left over chicken and I added in capsicum and onion. Absolutely delicious
Diane
This looks totally scrumptious
Annie
Looks delicious will definitely try this !
