These birria quesadillas are rich, tender, and full of juicy flavor. They take some time, but most of it is just waiting for the meat to cook. You can easily adjust the saltiness and spice to your taste.
To start, heat some olive oil in a large frying pan over medium-high heat. Meanwhile, season the chuck roast with ground salt and black pepper.
Add the chuck roast to the pan and fry it on each side for about 2 minutes, or until it becomes beautifully browned. Remove it from the heat and set it aside.
Next, lower the heat of the pan to medium. Add more oil if needed. Then, add the onions and sweat them for 2 minutes.
Then, add the minced garlic and spices to the onions. Give these ingredients a good stir while they fry for another 2-3 minutes.
Add 1 cup of water and vinegar to the ingredients. Mix them well and allow the mixture to come to a simmer.
Remove the base from the heat and add it to a blender. Blend the ingredients together at alow speed. This will be your marinade.
Cook the Birria stew
Cut your browned chuck roast into a couple of big pieces. Then, add it into your instant pot with the marinade. Ensure that all the meat is covered well with the spicy mixture.
Put the instant pot or your regular pot at a high and cook your meat for 45 minutes. After the time has elapsed, allow the steam to release slowly over 10-15 minutes. During this time, the meat will continue cooking.
Once the pot is ready to be opened, remove the meat from the concentrated sauce and set it aside.
Shred the meat into chunky pieces and place it inside a bowl.
Assemble the Birria quesadillas
Dip each corn tortilla into the concentrated beef sauce in the instant pot.
Then, take a big scoop of shredded Birria meat and place it inside a folded tortilla. Top it with the shredded cheese of your choice.
Finally, heat a frying pan over medium heat. Then, place the folded and filled tortilla inside the pan. Allow the tortilla to toast for 2-3 minutes or until the cheese starts to melt.
Serve your quesadilla Birria immediately with come extra Birria sauce on the side. You can garnish each with more sliced spring onions and fresh cilantro.
