Mustard & Peppercorn Sauce can be served with any meat cut including beef steak, pork or lamb chops, and it's my favourite sauce. It's quick, easy to make and you'll only need commonly found ingredients. If you don't eat dairy, use keto-friendly coconut milk instead - you won't be able to tell the difference!

Below I listed the average protein and fat content in a boneless strip or mignon steak. These cuts contain less fat than a ribeye steak if you are also watching your calorie intake on a ketogenic diet:

  • 200 g / 7.1 oz steak: 41 grams protein, 31 g fat
  • 250 g / 8.8 oz steak: 52 grams protein, 39 g fat
  • 300 g / 10.6 oz steak: 62 g protein, 47 g fat

Ingredients (makes 2 servings)

Steaks:
  • 2 small/ medium boneless strip or filet mignon steaks (400 g/ 14.1 oz)
  • 1 tbsp ghee or lard
  • salt and pepper to taste (I like pink Himalayan salt)
Mustard & Peppercorn Sauce:

Instructions

  1. There are two methods you can use to cook your steak depending on its thickness. If the steak is thick (1 1/2 - 1 3/4 inch / 4 - 4 1/2 cm), follow the instructions for Reverse-Seared Steak that requires both oven baking and pan searing. Otherwise, for thinner cuts, follow my guide to cook the steak on a pan. Once the steaks are cooked, transfer them onto a wire rack, loosely cover with a foil and let them rest for about 10 minutes before serving. Steak with Quick Mustard & Peppercorn Sauce
  2. Meanwhile, prepare the mustard & peppercorn sauce. Add the remaining ghee to the pan where you cooked the steaks. Crush the peppercorns slightly using a rolling pin or a mortar and pestle. Steak with Quick Mustard & Peppercorn Sauce
  3. Place in the pan and cook over a medium-high heat for 2-3 minutes, until fragrant. Add the onion powder, mustard, cream and bone broth and reduce the heat to medium. Bring to a boil and let the liquid reduce by half.
    If using fresh onion, add to the pan and cook for 3-5 minutes before adding the peppercorns. Steak with Quick Mustard & Peppercorn Sauce
  4. Cook for 3-5 minutes or until creamy.

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.

Do the macros given for this recipe include the meat, or just the sauce alone?
