Reverse Sear Prime Rib, KetoLuxe, Chef Alexa Lemley

Reverse Sear Prime Rib

I enjoy exploring novel ways to cook foods. I find many of them to be better than the traditional methods. A perfect piece of prime rib is evenly roasted and has a beautiful even red color. With traditional high-heat roasted prime rib, you can get an uneven piece of meat with an unappealing gray circle. When I discovered Reverse Sear Prime Rib, I knew I would never go back to the old ways.

Now that I cook keto, Reverse Sear Prime Rib is even better. Why? Because I traded in the traditional seasonings a gluten-free, sugar-free low carb version. My Hunter’s Blend accentuates the umami and brings out the hearty beefiness of prime rib. Rosemary, thyme, and mushroom powder are my secret ingredients. A simple symphony of flavors combined with a slow and low cooking method yields a perfect roast beast.

Prime rib is a show stopper. Who doesn’t love seeing and smelling a large, impressive piece of meat as it comes out of the oven?

Holidays are a time of indulgence. My Reverse Sear Prime Rib fits the bill. Serve with Gourmet Cranberry Sauce, Horseradish Whipped Cream, Yorkshire Pudding, and Creamed Spinach for a decadent feast. Knowing that everything is gluten and sugar free? That’s KetoLuxe.
