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 Slow Cooker 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.
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. Rub the meat with Penzey’s Pork Chop Seasoning if you have some and brown well on both sides. Put the browned pieces into the Crock-Pot Casserole Crock Mini or any 3-4 slow cooker.
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.) 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.) Pour sauce over the meat in the slow cooker.
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.

Low-Carb Slow Cooker (or Pressure Cooker) Pork Roast with Spicy Peanut Sauce
A craving for peanut butter led to this recipe for Slow Cooker (or Pressure Cooker) Pork Sirloin Roast with Spicy Peanut Sauce.
- 2-3 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
- 1 T minced fresh ginger (ginger from a jar is fine for this)
- 1 T minced fresh garlic (garlic from a jar is fine for this)
- 1/4 cup smooth natural peanut butter (Choose peanut butter with the least sugar, I like Adams 100% Natural Peanut Butter.)
- 1/4 cup tomato sauce
- 3 T soy sauce (use gluten-free soy sauce if needed)
- 3 T Stevia in-the-raw Granulated, 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
- 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.)
- 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.
- While the meat browns, in a food processor or the bowl attachment of an immersion blender, combine the minced ginger, minced garlic, peanut butter, and tomato sauce and process until the ingredients are well-combined.
- Add the soy sauce, Stevia in-the-raw Granulated or sweetener of your choice, Chile Garlic Paste, and chicken or vegetable stock and process again until everything is mixed.
- 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.)
- 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 (test it with a meat thermometer.)
- When it’s done, remove meat from the slow cooker and let it rest for a few minutes.
- If the sauce looks separated, whisk it for a minute to combine.
- Slice meat against the grain into slices about 1/2 inch thick and serve with sauce drizzled over.
Pressure Cooker Instructions:
- 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.
- 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.
- 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.)
- When the sauce is hot, cut the meat into slices against the grain.
- 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.
I originally used a Crock-Pot 2.5-Quart Slow Cooker for this recipe. This time I made it in the Crock-Pot Casserole Crock Mini; any small slow cooker will work. I’m also going to give directions below for making this in the Instant Pot, Cuisinart Electric Pressure Cooker, or another electric pressure cooker.
