Today’s recipe comes to you from my friend Diane’s newest book: Keto Quick Start: A Beginner’s Guide to a Whole-Foods Ketogenic Diet. It has over 100 keto recipes, four weekly meal plans, more than a dozen easy meal ideas (no recipe required!), and troubleshooting tips and tricks. It also features a unique and easy-to-use template that makes tracking your food quick and simple.

Why we love this book: Keto Quick Start targets everyday real-world concerns such as what to expect in the first few weeks and how to know if you’re on the right track, how to determine if you need more carbs and how to incorporate those carbs in a healthy way, how to customize keto for your personal goals (especially weight loss), and things to be aware of if you’re concerned about a particular health issue.

If you are at all curious about the keto diet and the possibly benefits it could have on your life you need to own this book. We’re lucky to live in a world where there is a wealth of information about the different ways we can nourish our bodies to make us feel our best, and Diane’s newest book is a shining example of that.

And let’s talk about this Cajun Pork Tenderloin! Like a lot of recipes in Keto Quick Start, this one isn’t overly complicated, utilities pantry staples like dried spices and is so delicious! It’s a unique take on the typical mustard and pork combo and pairs so well with most veggies for an easy weeknight dinner. It utilizes a quick sear on the stove top, and then it finishes cooking in the oven.

What to serve with this pork tenderloin:

Pork tenderloin keto

Slice into the thickest part of the loin and check that the tenderloin is pale with juices running from the cut. Look for meat that is mostly white with a slight hint of pale pink. We also love our kitchen BFF, the Thermapen! The pork is done at a temperature of 145ºF.

    It looks amazing! I only know 1 or 2 pork recipes, and this is something I really would love to try. Saved it on my phone to make on next weekend dinner. I would love to have it with mint chutney.
