This Roasted Garlic & Red Wine Chuck Roast over Cauliflower Mash recipe makes an easy, filling meal that’s sure to comfort! Ketogenic, low carb, gluten free



For Chuck Roast:

  • 2 pd chuck roast
  • 1 cup red wine
  • 1 cup beef broth
  • 510 garlic gloves
  • 1/2 c pepperoncinis
  • 3 tbsp mayo (optional, see notes)
  • chives (for topping)

For Cauliflower Mash:

  • 1 head of cauliflower
  • 3 tbsp butter
  • 1/2 c heavy cream
  • salt and pepper (to taste)


  1. Take the chuck roast out of the fridge and season both sides with salt and pepper. Smear a thin layer mayo all over the roast (this helps give it a nice crust). If you don’t want to use mayo (you can’t taste it), you can rub it in olive oil instead. 
  2. Sear chuck roast in Instant Pot or in a pan on the stove. Once you’ve got good color on both sides, pour in wine and beef broth. Top with garlic cloves and pepperoncinis. 
  3. Set Instant Pot on meat setting for 1.5 hours (you can go down to 1 hour or up to 2, 1.5 is a happy medium). If you don’t have an Instant Pot, you can throw this in the crock pot after searing for 4 hours on high or 8 on low.

For the Cauliflower Mash:

  1. While the roast is cooking, cut up cauliflower into florets. Boil water and salt it heavily. Once it comes to a boil, add in Cauliflower florets. Allow to cook for 5-7 minutes until they’ve softened. 
  2. Drain water. Add in butter and heavy cream. Mix using a mixer or put in a standing mixer. You can do it by hand but the mash will come out chunkier. Mix the butter and cream in well. Add salt and pepper to taste. I like to use quite a bit of salt to cut through the richness. 

For serving:

  1. Once chuck roast is done, you can shred it with a fork. Serve on top or on the side of the mashed cauliflower. Top with the garlic cloves from the roast! You can also pour some of the “sauce” (it’s thin, more like juice really) on top as well. Top with chives, if desired.


It might seem weird to rub the roast in mayo but this really helps get a good sear and create a good crust. If you’re still hesitant, you can just rub it in olive oil instead.
