How to Make Pork Loin in Tomato Sauce
-
Gather Ingredients: Make sure you have all the ingredients laid out and ready to go. This will streamline the cooking process and ensure nothing is overlooked.
-
Prep Pork: Cut the pork roast into 2-3 inch chunks, ensuring uniform pieces for even cooking. Dice the sweet onion separately, using a different cutting board to avoid cross-contamination.
-
Parboil Tomatoes: To easily peel fresh tomatoes, immerse them in boiling water for 30-40 seconds, then plunge them into ice water to cool. Once cooled, the skins should slip right off!

Sear Pork: Heat vegetable oil in a Dutch oven over medium-high heat. Add the pork chunks and season with salt and pepper. Brown for 2-3 minutes until they’re golden on the outside.

Cook Onions and Chiles: Add the diced onion and cook until tender, about 4-5 minutes. Stir in the canned diced green chiles along with the prepared tomatoes and their juices, mixing everything together well.
-
Simmer: Cover the pot and reduce the heat to low. Let it simmer for 3-4 hours, until the pork is fork-tender, filling your kitchen with its mouthwatering aroma.
-
Thicken Sauce: After simmering, remove the lid and continue to cook, stirring occasionally, until the sauce thickens and concentrates in flavor, about 20-30 minutes more.
-
Serve: Dish up the tender pork with warmed tortillas on the side. Don’t forget to provide toppings for a delightful finish—refried beans, cheese, sour cream, or guacamole add a perfect touch!
