When I posted Instant Pot Salsa Chicken I talked about how I’ve been working on Instant Pot versions of some of my most popular slow cooker recipes. And this Southwestern Pot Roast is another slow cooker recipe that took a few tries to come up with an Instant Pot version, but the slightly-spicy Southwestern beef was so delicious in the Instant Pot and we loved the recipe we ended up with.

And this Southwest Pot Roast is extra low in carbs so it’s a great Keto Pot Roast recipe that only has five ingredients! Or if you still prefer the slow cooker, check out Slow Cooker Southwestern Pot Roast instead. Either way you cook it, this recipe was delicious served as pot roast, with some of the sauce spooned over.

And the spicy beef can also be shredded apart and served as tacos with my favorite Mission Carb Balance Low-Carb Tortillas (affiliate link) or Mr. Tortilla 2 Net Carb Multigrain Tortillas (affiliate link). Or make lettuce wrap tacos if you prefer, or eat the spicy Southwestern beef on taco salad, in burritos, or use it for a Cauliflower Rice Taco Bowl. No matter how you eat it, this will be a dinner idea that’s easy and delicious; enjoy!

What gives this pot roast the Southwestern Flavors?

It’s the Pace Picante Sauce that gives this pot roast such great Southwestern flavors, and I love that it doesn’t have added sugar. If you want a bit more spicy flavor, you could also add a can of diced green chiles (affiliate link) when you put it in the Instant Pot.

Is this a Keto Pot Roast Recipe?

If you use a low-sugar salsa like the Pace Picante Sauce (affiliate link) that I’m such a fan of, this Instant Pot Southwestern Pot Roast will have about 3 carbs in a serving and 12 grams of fat, so it’s great for Keto diets.

Assembling Southwestern Pot Roast in the Instant Pot:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

  1. Start reducing beef broth in a pan on the stove or in the Instant Pot (affiliate link). (We experimented and the pot roast was definitely more flavorful when the broth was reduced before pressure cooking, instead of reducing the sauce at the end. We liked reducing the stock and browning the meat on the stove which is what the photos show.)
  2. Trim the roast to remove visible fat (as much as you prefer), and season the meat with Kalyn’s Montreal Steak Seasoning or your favorite steak seasoning (affiliate link).
  3. Heat oil in a large frying pan and brown the meat well (or use the Instant Pot and brown it in two batches.)
  4. Put all the browned beef in the Instant Pot.
  5. Then add the reduced beef stock to the pan and cook until it’s reduced to about 1/2 cup, scraping off the browned bits from the pan. (It may or may not already be reduced that much.)
  6. Add 3/4 cup salsa to the reduced broth, mix, and then pour that cooking sauce over the meat in the Instant Pot.
  7. Set Instant Pot to MANUAL, HIGH PRESSURE and 35 minutes.
  8. Let the Instant Pot release pressure manually when the time is up.

Finishing the Southwestern Pot Roast:

  1. Remove the meat to a cutting board.
  2. We used a Fat Separator (affiliate link) to remove some of the fat from the cooking liquid, but that’s probably optional if you trimmed your meat well.
  3. Then add about 1/2 cup more salsa to the sauce. We used the Instant Pot to warm it while we cut the meat apart.
  4. Serve hot, with the sauce spooned over the meat.

Instant Pot Southwestern Pot Roast is an easy low-carb dinner that the whole family will love!

Ingredients

  • 1 can (14.5 oz) reduced sodium beef broth, reduced until it's 1/2 cup strong broth
  • 3 lb. beef chuck roast, visible fat trimmed and cut into several pieces (see notes)
  • steak seasoning of your choice to rub on the meat (see notes)
  • 2 tsp. olive oil for browning meat
  • 3/4 cup + 1/2 cup low-sugar salsa (see notes)

Instructions

  1. Start reducing the can of beef broth in a pan on the stove or in the Instant Pot (affiliate link) while you brown the meat. (We liked reducing the stock and browning the meat on the stove, but take your choice on that.)
  2. Trim the roast to remove visible fat (as much as you prefer), and season the meat with Kalyn's Montreal Steak Seasoning or your favorite steak seasoning (affiliate link).
  3. Heat the oil in a large frying pan and brown the meat well (or use the Instant Pot and brown it in two batches.) Put the browned beef in the Instant Pot.
  4. Then add the reduced beef stock to the pan and cook longer as needed until it's reduced to about 1/2 cup, scraping off the browned bits from the pan. It may or may not already be reduced that much. (If you chose to brown the meat in the Instant Pot, just reduce the stock to 1/2 cup in the saucepan and then add salsa and pour over the meat in the Instant Pot.)
  5. Add 3/4 cup salsa to the reduced broth and pour that cooking sauce over the meat in the Instant Pot.
  6. Set Instant Pot to MANUAL, HIGH PRESSURE and 35 minutes. Let the Instant Pot release pressure manually when the time is up.
  7. Remove the meat to a cutting board.
  8. We used a Fat Separator (affiliate link) to remove some of the fat from the cooking liquid left in the Instant Pot; optional. Then add about 1/2 cup more salsa to the sauce. We used the Instant Pot to warm it while we cut the meat apart.
  9. Serve hot, with the sauce spooned over the meat.

Notes

I started with a roast that was nearly 4 pounds before I trimmed it. We used Kalyn's Montreal Steak Seasoning for this recipe, but there are many good brands of purchased steak seasoning. We used Pace Picante Sauce Medium (affiliate link) for this recipe but if you're making this for kids you might prefer mild salsa.

This recipe adapted for the Instant Pot from Low-Carb Southwestern Pot Roast in the Slow Cooker.
