Instant Pot Garlic-Butter Prime Rib and Mashed Potatoes

Sunday FUN-day, and ohhhh what a fun day it was. Yesterday was filled with family, sunshine, boat rides, fishing, and lots of amazing food! (Maybe a few adult beverages, too! 🤪) 

After spending much of the day outside, we just wanted to relax in the AC, but we had cravings for that quality steakhouse type of dinner. Driving anywhere was certainly out of the question, so was grilling and standing over more heat. So once again, we busted out the Instant Pot and let the creativity take control! Boy and I sure glad that we did. This was exactly the type of meal we were craving, and it couldn’t have turned out any better! 

Before you get to bashing and saying, “yuck, boiled steaks,” or, “steak shouldn’t be cooked in the IP!” SAVE IT..because frankly, I don’t want to hear it. I DO WHAT I WANT! 👊🏻

This entire dinner was from scratch to table in about 30-minutes, without having to worry about standing there flipping my steaks over the grill. And we all know how long potatoes take to boil...NO THANKS!! 

Ok..that’s enough..get out from behind your keyboard and GET COOKING!!

Instant Pot Garlic-Butter Prime Rib & Mashed Potatoes


  • 1-2  16oz. boneless rib-eye steaks (You CAN cook more, just saute them 2 at a time and then layer)
  • 6oz. garlic butter (some for serving)
  • 16oz. beef broth
  • 4lbs. golden potatoes, diced
  • 2 tsp salt
  • 2 tsp pepper
  • 4 Tbsp corn-starch
  • Aluminum foil


  1. Press saute mode on your Instant Pot. While warming up, season each side of your rib-eye steaks with salt and pepper.
  2. When hot, add 4 Tbsp of garlic butter, followed by your rib-eye steaks. Watch closely, and cook until nice and brown on each side.
  3. Remove steaks to deglaze your pot if necessary. Add 16oz. of beef broth to bottom of pressure pot, and then gently place your steaks back in the pot.
  4. In a separate cooking dish, add 1 cup water, 4 Tbsp garlic butter, and your diced potatoes. Cover with aluminum foil.
  5. Lay trivet on top of your steaks, followed by your potato dish. Close and seal lid. Cook on manual HIGH-pressure for 15-minutes. Allow for a 10-minute Natural Pressure Release. 
  6. Open lid, remove potatoes and your rib-eye steaks. Mash your potatoes by hand or using a mixer. (Mixer is much easier as it allows you to keep a closer eye on your gravy in Step 7)
  7. Press saute mode and add 4 Tbsp corn starch to the remaining broth mixture and whisk constantly until gravy starts to thicken.
  8. Spread desired amount of garlic butter over steaks, top mashed potatoes with gravy and ENJOY!!!
