Happy Holidays everyone! This is my favourite way to cook Brussels sprouts - drizzled with butter and lemon juice. Super simple and full of flavour!

I like them plain and served with crispy roast turkey but you can add Pancetta, grated parmesan cheese or toasted pine nuts, cashew nuts and flaked almonds. They also taste amazing with cream and wild mushrooms and are great when served with my Keto Cheese Sauce.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Omg I juat made these and added 3 cloves of crushed garlic and some additional pepper and wow. Sooo good! My boyfriend who hated them now likes them! Yay!

Oh that is amazing, I'm glad he changed his mind! 😊

I actually used to hate brussels sprouts but that has changed with keto. I've heard that in the UK they started a new type of sprouts which tastes less bitter and more sweet... maybe that's why we eat more BS than ever before :-D Thanks for the recipe, have to try BS with lemon 😊

That's interesting, I've always liked Brussels sprouts and I think it's mainly the cooking method that affects their taste. Lemon or lime - both work great!
