Low Carb Eggplant Zucchini Parmigiana: an old-time Italian classic transformed and ketofied to reduce carbs, but still yummy!
The classic Parmigiana is an Italian favourite and extremely well-known dish. I am sure that Italian foodies will cringe at my ketofication. But a girl’s got to do what a girl’s got to do to make her favourite recipes keto-friendly, right? And so I have.
To make a Classic Parmigiana you use aubergines (eggplants) that you need to coat in batter and deep-fry. I’ve used aubergines together with courgettes (zucchini) because the latter contains fewer carbs. Instead of coating them in batter and frying them, which is an unhealthy way of eating veggies, I boiled them for a few minutes.

My low carb eggplant zucchini parmigiana doesn’t even require you to salt each aubergine slice. I always used to hate that process because it takes long and it’s really tedious: slicing, sprinkling salt all over, letting the bitter juices drip out, rinsing and drying each slice. It takes forever and there is so much washing up involved! By boiling instead of frying, there is no need for any of it. Just slice, put in salted water and boil for 5 minutes. Much simpler! 
I used round zucchini fresh from my garden. These round babies taste the same as their usual oblong cousins, but have the added advantage that slices are bigger and therefore perfect for this dish.
A Parmigiana that’s really easy to make and tastes amazing!
If you’ve been reading any of my other posts, you already know that I like things simple but tasty. This dish is no exception. What makes it stand out is my tomato sauce. I’ve seen plenty of recipes for Parmigiana that simply use passata (sieved tomatoes) straight from the bottle and onto the aubergines. That’s a sure way to make the dish taste bland and unappealing. Not this recipe! If you read on you’ll discover how to make a really delicious tomato sauce, in 5 minutes, with some truly healthy ingredients: cinnamon, nutmeg, cloves, black pepper.
You can serve this Parmigiana with any white or red meat. It goes well with pretty much everything. I chose to serve mine with some lovely zero carbs skinless pork sausages on the day I made it and with grilled chicken next day. Did I tell you that my Low Carb Eggplant Zucchini Parmigiana tastes even better re-heated?

I’m going to try this your way as I’ve faffed with sliced aubergines brushed individually and baked in oven beforehand and your version is much simpler! I’m interested in where you get the no carb sausages though…thanks
Hi Margaret, I buy zero carb sausages from my local butcher, who makes them without fillers for me. If you have an Italian deli near you, it’s worth checking it out, as Italian packaged sausages are usually zero carbs too.
