Hello k_sharma, happy to help you with your meal prep!
For standard supermarket pork ribs cooked at 180 degrees Celsius (350 degrees Fahrenheit), the ideal baking time is between 1.5 to 2 hours, depending on the specific cut and thickness. If you have baby back ribs, 90 to 100 minutes is usually the sweet spot. If they are spare ribs or St. Louis style, expect them to need closer to 2 hours to become tender.
To keep the meat juicy and prevent it from drying out over three days of meal prep, I recommend using a tight foil packet method. Season your ribs thoroughly with your dry rub, then wrap the rack tightly in heavy-duty aluminum foil. Adding a tablespoon of liquid such as apple juice, apple cider vinegar, or stock inside the foil pouch helps generate gentle steam, breaking down collagen without draining moisture from the meat.
Bake the foil packet at 180 degrees Celsius for 90 to 110 minutes. Afterwards, carefully unwrap the top of the foil. If you enjoy a caramelized crust or barbecue sauce finish, brush on your sauce and return them to the oven uncovered for an additional 10 to 15 minutes.
Since you are prepping these for three days, proper cooling and storage are vital. Allow the ribs to cool completely before portioning and storing them in airtight containers in the fridge. When reheating a portion, cover it loosely and add a small sprinkle of water or extra sauce to maintain that tender texture. Best of luck with your batch cooking!
