Pork simmered in a creamy peanut-chile sauce until tender and richly coated. This protein-packed family dish brings Mexican nut-based sauce traditions to a hearty, comforting meal.
Pat pork shoulder dry and cut into 2-inch chunks for even braising.
Heat 1 tbsp oil in a large Dutch oven over medium-high heat; brown pork pieces on all sides, working in batches. Set aside.
Add remaining oil, sauté diced onion and garlic until fragrant, about 3 minutes, then stir in anchos and roast for 1 minute (do not burn).
Transfer vegetables and chiles to a blender; add tomatoes and peanuts. Blend with 1 cup chicken broth until ultra-smooth.
Return pork and sauce to the pot. Add remaining broth, season with salt and pepper, bring to a simmer, then reduce heat to low, cover, and cook for 1.5 hours, stirring occasionally for even sauce adherence.
Uncover and simmer 10–15 minutes more to thicken the sauce as desired before serving.
