Add adobo sauce, chipotle pepper, red onions, garlic, black pepper, cumin, Mexican oregano, and olive oil to a food processor or blender and puree until smooth. If you like less spice, add less peppers (or even JUST the adobo sauce!). If you add all of the peppers, this will be hot! 7 oz chipotle peppers in adobo sauce, 1 Red onion, 6 cloves garlic, 1 tsp black pepper, 2 tsp ground cumin, 2 tbsp Mexican oregano, ¼ cup olive oil
Marinate the chicken and refrigerate for at least one hour or up to 24 hours. I love freezing this marinade with the chicken, so it thaws and marinates at the same time. 3 lbs chicken breast
Preheat your oven to 350°F, cook the chicken until it reaches an internal temperature of 165°F, about 30 minutes.
Serve warm, or place in individual serving containers for meal prep.
