Step 1

Core and toast the chiles. Slice the stems off of the dried chiles, then remove and discard the seeds inside. Press the "Sauté" button on the Instant Pot. Add the chiles and cook for 1 to 2 minutes per side, flipping once, until the chiles are fragrant and lightly toasted. Transfer them to a blender (or food processor) and set aside.

Step 2

Sauté the veggies. Add the oil and onion to the hot Instant Pot. Sauté the onion for 4-5 minutes, stirring occasionally, until softened. Add the garlic and tomatoes and sauté for 3 more minutes, stirring occasionally. Then turn off the Instant Pot, and transfer the entire mixture to the blender.

Step 3

Blend the marinade. Add 2 cups of the beef stock, the apple cider vinegar, cumin, oregano, ginger, cinnamon and cloves to the blender. Cover and carefully* blend for 1 minute, until the mixture is completely smooth. Set aside.

Step 4

Sear the meat (optional). (You can skip this step if you'd like to save time.) Briefly rinse out and dry off the Instant Pot insert. Season the beef with a few generous pinches of salt and black pepper. Press the "Sauté" button on the Instant Pot and add in 1 tablespoon of the oil. Add half of the beef and briefly sear it in the oil, turning the chunks occasionally so that they can sear on all sides. Transfer the first batch of beef to a clean plate, then sear the remaining beef likewise in the remaining tablespoon of olive oil. Turn off the Instant Pot.

Step 5

Pressure cook. Add all of the seared beef to the Instant Pot, along with the blended marinade, bay leaves and remaining 2 cups of beef stock, and give the mixture a quick toss. Cover and set the lid to "Sealing." Pressure cook on "Manual" for 45 minutes, followed by a quick release.

Step 6

Shred the beef (optional). Carefully remove the lid once all of the pressure has released. Remove and discard the bay leaves. Then you can either choose to just leave the beef in larger chunks for serving. Or you can use two forks to shred the beef into bite-sized pieces, and then toss the shredded beef in the marinade so that it is evenly coated.

Step 7

Season. Taste and season the birria with additional salt and pepper, if needed.

Step 8

Serve. Serve the birria in bowls (the beef along with its broth) garnished with lots of your favorite toppings, with a side of warm tortillas, and enjoy!
