It’s true that I never liked peanut butter sandwiches when I was a kid (and still don’t) but I love recipes using peanut butter, especially if the recipe has a spicy Asian twist to it. This Low-Carb Pork Roast with Spicy Peanut Sauce is a recipe I came up with about five years ago when I had a pork sirloin roast I wanted to cook, I had a lot of work to do, and I was craving peanut butter.

I enjoyed a couple of slices of the roast pork for dinner, and the next day I diced up some of the leftover meat and ate it inside lettuce leaves, and I thought it was great both ways. Now flash forward a few years, and I still love the recipe and thought I could improve on the photos. And I know that in 2017 someone is going to ask about making this in the Instant Pot, so I’m going to add some pressure cooker directions for this favorite way to cook pork roast just for those of you who’d like to make this recipe in the pressure cooker instead.

This time I cut the pork roast into some pieces to brown it, and also cooked it in my Crock-Pot Casserole Crock Mini, a flatter, oval shaped slow cooker that gives a you more surface area so more of the meat is covered with sauce when it cooks. But you can make this in any smallish slow cooker you have and it will work beautifully.

How to Make Low-Carb Slow Cooker (or Pressure Cooker) Pork Roast with Spicy Peanut Sauce:

(Scroll down for complete printable recipe.)

  1. I used one of those inexpensive pork sirloin tip roasts that come in a four-pack at Costco. Trim the roast if needed and cut into several pieces, cutting with the grain so you can cut slices against the grain when it’s cooked.
  2. Rub the meat with Penzey’s Pork Chop Seasoning (affiliate link) or any spices you like on pork and brown well on both sides.
  3. Put the browned pieces into the Crock-Pot Casserole Crock Mini (affiliate link) or any 3-4 slow cooker.
  4. Combine minced ginger, minced garlic, peanut butter, tomato sauce, soy sauce, sweetener, and stock to make the sauce. I buzzed it in the bowl attachment of my immersion blender (affiliate link).
  5. If you’d like, put the sauce in the pan you browned the meat in and cook for a few minutes, scraping any browned bits off the bottom. (You can skip that step completely.)
  6. Pour sauce over the meat in the slow cooker.
  7. Cook on low for 2-3 hours, or until an Instant Read Meat Thermometer (affiliate link) shows the pork has reached at least 145F/65C. (The USDA lowered the safe cooking temperature for pork a few years ago.)
  8. Cut meat into slices against the grain and serve hot with some of the sauce spooned over, and with extra sauce to add at the table if desired.

A craving for peanut butter led to this recipe for Slow Cooker (or Pressure Cooker) Pork Sirloin Roast with Spicy Peanut Sauce.

Ingredients

  • 3 lb. pork sirloin roast, fat trimmed
  • 1 tsp. Penzey’s Pork Chop Seasoning, for seasoning the pork before it’s browned (or use any seasoning blend that’s good on pork)
  • 2 tsp. olive oil

Sauce Ingredients:

  • 1 T minced fresh ginger (see notes)
  • 1 T minced fresh garlic (see notes)
  • 1/4 cup smooth natural peanut butter (see notes)
  • 1/4 cup tomato sauce
  • 3 T soy sauce (use gluten-free soy sauce if needed)
  • 3 T Golden Monkfruit Sweetener or sweetener of your choice
  • 2 tsp. Chile Garlic Paste (or more if you really like it spicy; check label for gluten-free)
  • 1/4 C chicken or vegetable stock

Instructions

  1. Trim any visible fat from the pork sirloin roast and cut with the grain into several pieces (so you can cut slices against the grain when the meat is done); then rub the roast on all sides with Penzey’s Pork Chop Seasoning, or a seasoning mix of your choice that’s good on pork. (You could use just a blend of garlic powder, salt, and pepper if you don’t have anything else that will work.)
  2. Heat the oil in a heavy frying pan over high heat and brown the roast well on all sides. Put browned pieces of pork into the slow cooker.
  3. While the meat browns, in a food processor or the bowl attachment of an Immersion Blender (affiliate link), combine the minced ginger, minced garlic, peanut butter, and tomato sauce and process until the ingredients are well-combined.
  4. Add the soy sauce, Golden Monkfruit Sweetener (affiliate link) or sweetener of your choice, Chile Garlic Sauce (affiliate link) and chicken or vegetable stock and process again until everything is mixed.
  5. If you want to add flavor, put the mixed sauce into the frying pan and cook over low heat for a few minutes, scraping any browned bits off the bottom of the frying pan. (You can skip that step if you prefer.)
  6. Pour sauce over the meat in the slow cooker. Cook on low for 2-3 hours, or until the roast is tender and internal reaches at least 145F. I would test it with an Instant Read Meat Thermometer (affiliate link).
  7. When it’s done, remove meat from the slow cooker and let it rest for a few minutes.
  8. If the sauce looks separated, whisk it for a minute to combine.
  9. Slice meat against the grain into slices about 1/2 inch thick and serve with sauce drizzled over.

Pressure Cooker Instructions:

  1. Trim and brown the meat as detailed above, but don’t cut meat into slices. You can brown the meat in the pressure cooker instead of a frying pan if you prefer. Then use the directions for Pork Sirloin Tip in the Pressure Cooker to cook the pork roast.
  2. While meat cooks, make the sauce mixture as described above. When the meat is done, and pressure has released, remove meat to a cutting board and discard the liquid in the pressure cooker.
  3. Let meat rest (cover with foil if you want to be sure it stays warm) while you simmer the sauce mixture in a frying pan for 5-10 minutes (or use the pressure cooker if you prefer, but I feel like you can control the heat better in a pan on the stove.)
  4. When the sauce is hot, cut the meat into slices against the grain.
  5. Serve meat with some sauce spooned over, or you can put the sliced meat into the sauce and cook a few minutes longer if you feel the meat isn’t hot enough.

Notes

I originally used a Crock-Pot 2.5-Quart Slow Cooker (affiliate link) for this recipe. This time I made it in the Crock-Pot Casserole Crock Mini (affiliate link); any small slow cooker will work. There are also directions for making this in the Instant Pot (affiliate link) or another electric pressure cooker.

Minced garlic and ginger from a jar is fine for this recipe. Choose peanut butter with the least sugar, I like Adams 100% Natural Peanut Butter.

  3. Can you not use the sauce in the instapot like you do in the crockpot?

    • You can try it, but I am doubtful that a sauce like this will hold up in the pressure cooker. I’m thinking it will separate. If you try it, I’d love to hear how it works.

  4. Your weekend prep recipes seem to be missing the piece about what you prepped on the weekend. Like this recipe. Did you do just the dry rub or did you put the pork in a marinade? Did you do all the cooking so you just warm it up? It seems to me that weekend prep would include as much attention as slow cooker and pressure cooker.

    • I am thinking you didn’t see the post that announced the Weekend Food Prep category? From that post, “What you’ll find in the Weekend Food Prep category are recipes that you can cook or prep on the weekend and then reheat and eat or assemble and eat during the week.”

      Weekend Food Prep on my site includes recipes you cook on the weekend that make enough servings you can eat it again one of two times during the week. It also includes things like salads where you chop it up on the weekend and eat some, but keep some to eat later during the week. I don’t have recipes that you prep ahead and cook later. Sorry if that was not clear.

  5. This recipe is fantastic. It is simple and very flavorful. We ate this with rice and broccoli for dinner (4 meals total) and one large lunch, just adding half a bag of Trader Joe’s frozen mixed vegetables to the meat.
    And thank you for turning me on to the pork roasts at Costco! Can’t wait to try your other recipes using them.

  6. This was delicious! My husband and I just started SB and are on phase 1. This definitely broke up our mononity! I will be trying a lot more of your receipes.

  9. This recipe is amazing. I mean, like lick the plate good. The only change I made was to up the peanut butter from 1/4 cup to 1/3 cup (we love peanut butter). I used Monkfruit sweetener and my own spice rub for the pork. I will be making this again (and again).

  10. Link to Chili Garlic Paste did not work. What do you recommend?

    • Makes me crazy when companies change their websites like that, sorry I didn't notice it! I buy either Huy Fong Chili Garlic Paste (which is widely available even in grocery stores or this one that I wrote about on the blog. I think they're quite similar but the Huy Fong might be slightly hotter. Hope that helps. Will make the link go to Amazon for people who can't find it in their store.
