If you’re short on time but need a good-for-you keto side dish that’s also impressive enough to serve to guests, you can’t do better than this buttery herbed spinach & cauliflower mash!

Cauliflower is the perfect alternative to starchy potatoes, and if prepared the right way, you won't even know there are no potatoes. You can do that by adding flavor from caramelized onions, garlic and butter, and by blending it until very smooth and creamy.

This cauliflower mash is different because it uses two nutrient-packed vegetables — spinach and watercress. It's so good for you that I decided to call it "superfood" mash. This mash is diabetic-friendly and has the perfect balance of healthy fats and nutrient-dense vegetables. This recipe is a great example of a healthy Mediterranean keto approved recipe which emphasizes the importance of healthy fats and nutrient density (even better if you swap the butter with extra virgin olive oil!)

You can serve this creamy cauliflower mash with any proteins such as roast chicken, pan-fried salmon, pork chops, tenderloin, lamb chops, and any seafood.

This creamy green mash recipe is originally from my Beginner's KetoDiet Cookbook. Check it out for over 100 more delicious low-carb recipes!

  • 1 medium cauliflower, cut into florets (600 g/ 1.3 lb)
  • 1 small yellow onion, chopped (70 g/ 2.5 oz)
  • 1 clove garlic, minced
  • 1 tbsp ghee or extra virgin olive oil (15 ml)
  • 150 g fresh spinach (5.3 oz)
  • 50 g fresh watercress or more spinach (1.8 oz)

  • 1/4 cup fresh basil or parsley

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.
