How long can I dry-age prime rib in my fridge at home?

For home kitchens, 3–7 days is the sweet spot. You’ll get better flavor and texture without the risk of spoilage. Professional dry-aging can go longer, but your fridge doesn’t have the same airflow or humidity control.

Do I need a special fridge to make dry-aged style prime rib?

No, you can use your regular kitchen fridge. Just wrap the roast lightly in paper towels or cheesecloth, place it on a rack with a pan under it, and keep it in the coldest part of the fridge. Change the towels if they get damp.

What’s the best way to cook fridge-aged prime rib so it stays juicy?

The reverse sear method works best. Cook the roast low and slow at 250°F until it’s just under your target doneness, then finish with a hot sear in the oven at 500°F to build a crust. Always let it rest before slicing.

Instructions

Pat roast dry and wrap loosely in paper towels or cheesecloth.
Place on wire rack over a pan and store in fridge for 3–7 days. Change towels if damp.
Trim thin dried edges from roast.
Season generously with salt and pepper (plus garlic or herbs if using). Rest in fridge uncovered for 2–4 hours or overnight.
Preheat oven to 250°F. Place roast fat-side up on rack over roasting pan.
Cook until internal temp is 120°F (rare), 125°F (medium-rare), or 135°F (medium).

Rest roast for 20–30 minutes before slicing thick.

Notes

Fridge-aging 5 days gives the best flavor without risk.
Use a thermometer for accuracy—don’t rely on time.
Keep seasoning simple to let the meat shine.
Leftovers taste great reheated in a skillet with butter.
