Pot roast is a stalwart recipe for a busy kitchen since it requires little prep and lots of time being ignored in a slow cooker or over low heat on the stove or in the oven. It’s one that’s incredibly easy to prep ahead of time, too.

I’ve included instructions for making mashed cauliflower from fresh- although you can always cheat and buy it pre-made, too! I really like the light, almost nutty flavor of mashed cauliflower as a foil against the comforting flavors of pot roast, but egg noodles, mashed potatoes, or even polenta work great instead, also.

I get riced cauliflower typically from the freezer section or in the pre-packed section of my grocery store, but it’s easy to make- just cut off the stalks and stems from fresh cauliflower, and blitz in the food processor or blender until the pieces are tiny. 

This recipe calls for dried rosemary, but if you’ve just got fresh on hand, divide the amount in half as fresh rosemary is a stronger flavor. The instructions below walk you through making for mashed cauliflower, but you can swap that out for mashed potatoes, egg noodles, or go straight for the sandwich.\

      You work hard. Dinner should be easy.

      At Percolate Kitchen, we believe that the “third shift” of getting dinner ready shouldn’t mean reinventing the wheel every evening.

      Recipes on our site are broken down into simple, step-by-step processes so you can be flexible with your time- make the meal fresh, prep the ingredients to assemble and cook later, or do a little bit of both.
