Keto slow cooker pot roast — fork-tender beef chuck with mushrooms and celery in rich brown gravy, garnished with parsley on a platter — Serving suggestion — your result will vary

Pot roast is made for keto — a cheap, tough cut of beef that turns meltingly tender after a long, slow braise, with all the savory comfort and none of the carbs once you leave out the potatoes. Mushrooms and celery take their place, and the slow cooker does everything while you're out. A generous serving lands around 5g net carbs.

The one step worth your time is searing the roast first. The browned crust is where most of the deep, roasted flavor comes from.

Ingredients

3 lb beef chuck roast
1 tablespoon olive oil
8 oz mushrooms, halved
3 celery stalks, cut in chunks
1/2 onion, sliced
3 cloves garlic, smashed
2 cups beef broth
2 tablespoons tomato paste
1 tablespoon Worcestershire sauce
1 teaspoon dried thyme
Salt and pepper
1/4 teaspoon xanthan gum (optional, to thicken)

Steps

Pat the roast dry and season well with salt and pepper. Sear it in the olive oil in a hot pan on all sides until deeply browned — don't skip this, it's most of the flavor.
Put the mushrooms, celery, and onion in the slow cooker and set the roast on top.
Whisk the broth, tomato paste, Worcestershire, garlic, and thyme together and pour it over.
Cover and cook on low 8 hours (or high 5), until the beef shreds easily with a fork.
Lift out the roast and rest it. To thicken the gravy, whisk in the xanthan gum and let it sit 5 minutes, then shred the beef and serve in the gravy.

Notes and swaps

Skip the potatoes and lean on low-carb vegetables — mushrooms, celery, radishes, and turnips all hold up to the long cook. Xanthan gum thickens the gravy without flour; add it sparingly and let it rest, since a little goes a long way. Serve over cauliflower mash to soak up the gravy. Leftover roast is excellent shredded into soups or eggs.
