Perfect Roast Beef in the Ninja Foodi

Making the PERFECT Roast Beef in the Ninja Foodi is so easy and incredibly delicious! 

You know that perfect thin slice of medium rare roast beef that you pile high onto a crusty roll and maybe dip into some Au Jus and call it a French Dip? Or slather it with BBQ sauce and call it a BBQ Pit Beef sandwich? Or whip up some mashed potatoes and gravy and call it Sunday Dinner!

That's what we are making today! Perfectly cooked Roast Beef in the Ninja Foodi! Before we get into the directions for this super easy Roast Beef in the Ninja Foodi, let's talk about the differences between this recipe and pot roast. 

Differences between Roast Beef and Pot Roast

Roast Beef and pot roast are not the same thing and the differences are in the cuts of meat used, in the cooking method, and how we serve it.

Roast beef is used mostly for sandwiches, although it is pretty good piled up high next to mashed potatoes and green beans for Sunday's dinner, too.

Pot roast, like this Quick & Easy Pot Roast made in the Foodi, is also delicious for Sunday's dinner, but it doesn't slice like roast beef does. It makes a great pulled beef style sandwich, but not a deli roast beef style sandwich. 

Roast Beef is usually roasted dry, meaning no liquid in the pot. Pot Roast on the other hand, usually uses a braising liquid. 

You want fattier cuts of meat for a pot roast, those that come from the shoulder area of the cow work best. My favorite cut of meat for a pot roast is the chuck roast. 

For roast beef, you want a cut that doesn't fall apart when sliced. 

What are the best cuts of meat for a Roast Beef? 

The best choice is the top round and that is what we are using in this recipe. Any cuts from the round will work, but the eye of round and the bottom round won't be as tender. 

The round cuts come from the hindquarter of the cow and are considered tough cuts of meat. This muscle is worked hard and round cuts are very lean, yet flavorful cuts of meat. 

The best way to serve them is medium rare and make sure you cut across the grain. If you don't cut across the grain, the meat will be tough. It is also important to slice very thin slices for the best flavor and texture. 

I know, not everyone likes rare roast beef, so I will include suggested cooking times if you like your roast beef well done. 

Cooking Times & Temps for Roast Beef in the Ninja Foodi

*all cooking times are based on a 3 pound top round roast -- adjust times according your size roast. These are estimates only. Please use a good quality meat thermometer for accuracy. 

** The FDA recommends cooking beef roasts to an internal temperature of 145° F/ 63° C. There is a great article on times, temps, meat safety and other information right HERE. 

I like my roast beef: 

• Rare: Cool red center. For rare roast beef, broil for 20 minutes and let sit in the hot pot with the Ninja Foodi turned off for about 20 minutes. The internal temperature should register about 125 F/ 52° C. 
• Medium-Rare: Warm red center. For medium-rare roast beef, broil for 25 minutes and let sit in the hot pot, with the Ninja Foodi turned off, for 25 minutes. The internal temperature should register 135° F/ 57° C. 
• Medium: Warm pink center. For medium roast beef, broil for for 30 minutes and let sit in the hot pot, with the Ninja Foodi turned off, for 30 minutes. The internal temperature should register 145° F/ 63° C. 
• Medium Well: Slightly pink center. For medium-well roast beef, broil for 30 minutes, reduce heat to 300° and bake for 5-10 minutes. Let sit in hot pot, with the Ninja Foodi turned off, until internal temperature registers 150° F/ 66° C. 
• Well Done: Little or no pink. For a well-done roast beef, broil for 30 minutes, reduce heat to 300° and bake for 10-15 minutes. Let sit in hot pot, with the Ninja Foodi turned off, until internal temperature registers 160°F/ 71° C. 

If you are not cutting and serving your roast beef right away, remove from the Ninja Foodi at about 5 degrees below the desired temperature to allow for carry over cooking. Since the meat is hot when removed from the Ninja Food, it will continue to cook and usually the temp rises about 5 degrees in 10-15 minutes. 

How to slice Roast Beef for best results

The way you slice your roast beef greatly affects the tenderness. The top round, bottom round, or eye of round roasts are lean meats that can be tough and chewy unless they are sliced thinly and against the grain. 

Knowing which way the grain is going before you season and cook your roast is the best course of action, but no worries if you start to slice the roast and realize you aren't cutting against the grain. 

It happens to all of us and I'm actually happy that it happened to me while filming the video, which you can see right here: Roast Beef in the Ninja Foodi

I thought I knew the direction of the grain, but realized after cutting several slices that I was cutting with the grain and not against the grain. If this happens to you, just turn the roast around and start cutting against the grain. There is a difference in the way your slices will look, so you can easily tell if you are slicing it correctly. 

The thinner the slices, the more tender the roast beef will be. I have a very good meat slicer and it works perfectly, but unless you plan on slicing a lot of meat and cheese, the cost of a good slicer often isn't worth it. 

Instead, invest in a good knife. The one I use the most is a Chef's Knife from Pampered Chef. The model I have is on sale right now in the outlet (quantities are limited, so they might be sold out) and it is a good quality knife with a very reasonable price tag. 

When you slice roast beef correctly, you will be slicing against the grain. This cuts through the fibers in the meat and makes it much easier to chew. 

How to make the PERFECT Roast Beef in the Ninja Foodi

First, bring your roast to room temp. This will allow for even cooking and is the first step to a perfect roast beef in the Ninja Foodi. 

Second, season the outside of the meat generously! You can use the rub I used or any seasonings you prefer. Simple salt and pepper work great, but be sure to use a sea salt or Kosher salt and a course ground pepper for best results. 

Preheat the Ninja Foodi for 10 minutes on BROIL with the rack in the low position. You want to start cooking the meat right away and having the rack and the Foodi preheated really helps. 

Broil the roast on the rack in the low position for 25 minutes. Leave the roast in the Ninja Foodi with the lid closed and the Ninja Foodi turned off for 20-25 minutes. See cooking suggestions above if you want your meat cooked differently than medium-rare. 

Remove and let cool for about 10 minutes. Slice against the grain.

If you want to make an au jus, add ¾ cup of beef stock to the inner pot and sear/sauté on high. Scrape the brown bits off the bottom to incorporate with the stock. 

Serve & Enjoy!
