Yesterday we had the first snow of the year at my house, so I guess it’s time to think about low-carb comfort food that helps keep you warm. This delicious Slow Cooker Sweet and Sour Pot Roast is a recipe that fits that description for me, and I’ve made this often since I first posted the recipe. And although I really, really, really hate winter weather, I do love cold weather food!

I’m sure I don’t have to tell anyone that sticking to a carb-conscious eating plan is much more challenging during the holidays, and one thing that really helps me is to make recipes on the weekend that Can Freeze, divide the leftovers out into containers with one or two servings, and stash them in the freezer so I have plenty of easy low-carb options when I need dinner but don’t want to cook.

This Low-Carb Slow Cooker Sweet and Sour Pot Roast freezes beautifully, and I’ve already had the leftovers once for a quick dinner!

How to make Slow Cooker Sweet and Sour Pot Roast:

(Scroll down for complete printable recipe including nutritional information.)

  1. Trim the chuck steak so most visible fat is removed; you’ll probably have to cut it into pieces to do that. (I save the scraps to make beef stock.)
  2. Rub the pieces of meat with steak seasoning; then brown on all sides. (For best flavor, don’t skip this step of browning the meat.)
  3. Put the browned meat into the slow cooker.
  4. While the meat browns, puree the sauce ingredients, then cook it in a frying pan until it thickens.
  5. It should be thick enough that you can scrape the bottom and the sauce stays together like you see in the photo.
  6. Cover the meat with the sauce and cook on low for 7-8 hours (or a little longer won’t hurt) or on high for 3-4 hours.
  7. Serve hot, with extra sauce on the side.
  8. I love this with a little sour cream on top.

Low-Carb Slow Cooker Sweet and Sour Pot Roast will always be a hit when you need some winter comfort food.

Ingredients

  • 4 lb. boneless chuck roast, trimmed well
  • 2 tsp. olive oil
  • steak rub, to season meat (see notes)
  • black pepper, to season meat

Sauce Ingredients:

  • 1 T onion powder
  • 1 T garlic powder
  • 2 T ginger puree (see notes)
  • 2 T Monkfruit Sweetener or sweetener of your choice
  • 1/4 cup unseasoned rice vinegar
  • one 14 oz. can crushed tomatoes
  • 2 T soy sauce
  • 1 tsp. anchovy paste, optional

Instructions

  1. Trim as much fat as you can from roast, and cut if necessary to fit into Crockpot. Rub meat well with steak seasoning and black pepper.
  2. Heat olive oil in a large frying pan and brown roast well on both sides. This will take a few minutes; don’t rush the browning step. Put browned roast into slow cooker.
  3. Deglaze the pan while meat browns, combine onion powder, garlic powder, ginger puree, sweetener of your choice, rice vinegar, tomatoes, soy sauce, and anchovy paste (if using) in food processor. Process several minutes with steel blade until tomatoes are pureed and ingredients are well combined.
  4. Put the pureed sauce into the frying pan where you browned the meat and simmer on low heat until the sauce thickens; you should be able to draw a spoon through it and have the sauce stay together.
  5. Once it’s thickened to that point, pour sauce mixture over the meat in the slow cooker.
  6. Cook on low 7-8 hours (or more) or on high for 3-4 hours,  or until meat is very tender. (If I’m home I usually turn it a couple of times, but it’s not necessary.)
  7. Remove meat from slow cooker and keep warm. Skim off any visible fat from sauce mixture if needed, or use a fat separator (affiliate link).
  8. Slice the pieces of roast and serve hot, with sauce spooned over meat.

Notes

I used a Crock-Pot 3-1/2-Quart Slow Cooker (affiliate link) for this recipe. The recipe Can Freeze, so if you only have a bigger slow cooker I’d double it and stockpile some in the freezer for quick dinners later.

I used my homemade Montreal Steak Seasoning; use an approved seasoning for Paleo or Whole 30. Ginger Puree comes in a jar and in a jar and is also called ground ginger. I originally made this with granulated Stevia but now I'd prefer Monkfruit Sweetener (affiliate link). Don't use Seasoned Rice Vinegar which contains sugar.

If you remove fat with a fat separator as described, fat content will be lower than shown in nutritional information.

Some ideas for the sauce came from a recipe for Ginger Beef in 500 Low-Carb Recipes. You might want to read How to Make Pot Roast in the Crockpot before you make this recipe.
