Swap out fatty crusty quiche for a lighter, flavor-packed Spaghetti Squash Quiche with Kale and Mushrooms!
Spaghetti squash is a vegetable with a noodle-like flesh and a slightly sweet taste. It can easily replace pasta in a casserole (spaghetti squash casserole), make a low carb “noodle” boat (spaghetti squash boats Tex Mex) and now form a crust in this meaty and delicious gluten-free spaghetti squash quiche. Why not?!
You don’t have to squeeze the liquid out or any extra steps. Once pressed in a pie plate, spaghetti squash easily replaces traditional flour crust without extra carbs. Cheesy, meaty and so full of flavour. It melts in your mouth. Warm or cold, I love it both ways. I’m a huge fan of mushrooms and combined with leafy healthy green like kale, you can’t go wrong. This combination will blow your mind!
Besides swapping traditional crust for a spaghetti squash one, I replaced some cheese with cottage cheese and swapped a few eggs with egg whites. More protein and less fat. Healthy fat is good for you but again, in moderation. You won’t miss any cheese in this healthy spaghetti squash quiche.
How to Make Spaghetti Squash Quiche
Start off by baking some squash. It will be a bit undercooked and you will have to use some muscles to separate it into strands. The longer the squash cooks, more liquid it releases. And we don’t want to end up with a hot mess as the quiche bakes with a filling inside.
Then saute your mushrooms. Nice golden brown colour, just enough to release the excess liquid. Then kale. I added spices to kale on purpose, do not skip this important step to an aromatic spaghetti squash quiche. Trust me, I tested this recipe 3 times.
Whisk eggs, cottage cheese, cheese and spices together. Do not worry, cottage cheese will melt and incorporate with other ingredients beautifully. Nothing will curdle.
Then form a crust with your hands. Just press spaghetti squash to the sides and bottom of a pie dish. I used a deep pie dish but regular one will work just fine. I added a few spices to the crust as well. Nothing complicated – salt, black pepper and thyme. Can’t stand bland food.
Then mix kale and mushrooms with the liquids. Just until combined. Pour into the crust and press with spatula to dunk all vegetables in the liquid. This way the veggies won’t dry out as the quiche rises. You could even open the oven after 20 minutes of baking and press again.
I baked my spaghetti squash quiche for 50 minutes. Check with a knife and if it comes out clean, your quiche is ready.
Like with any casserole or pie, let it cool to ensure proper slicing, about 30 minutes. You might have to lift the edges of the crust with a knife a bit. Alternatively, you could spray the pie dish edges with a cooking spray before adding the ingredients to it.
