Best and Easiest Beef Roast Ever!

A foolproof oven method that delivers a perfect roast every single time

Back to Blog

This recipe is so easy and tastes so good. The key is to use a 5 lb. beef roast — preferably a sirloin tip, eye of round, or similar lean cut. You don't want a roast with any bone, fat, or gristle. The magic is in the method: a screaming hot oven followed by simply turning it off and walking away. Start it early in the morning and it'll be ready for dinner. No fussing, no basting, no peeking — just a gorgeous, juicy roast every single time.

Prep Time15 min
Cook Time1 hr active + several hours resting in oven
Servings8–10

Ingredients

  • 1 beef roast, approximately 5 lbs (sirloin tip, eye of round, or similar boneless lean cut)
  • 6–8 cloves of fresh garlic, sliced
  • Dried tarragon, to taste
  • Garlic powder, to taste
  • Cracked peppercorns, to taste
  • Water (for the pan drippings gravy)

Instructions

01

Preheat the Oven

Preheat your oven to 500°F and allow it to preheat for a full one hour. This step is critical — the oven must be fully up to temperature before the roast goes in.

02

Prep the Roast

While the oven is preheating, use a sharp knife to cut slits all over the roast. Stuff each slit with a slice of fresh garlic. Then generously sprinkle the entire roast with dried tarragon, garlic powder, and cracked peppercorns.

03

Roast at 500°F

Place the seasoned roast in a shallow non-metallic baking dish. Put it in the oven uncovered and roast at 500°F for exactly one hour. Do not open the oven door during this time — not even once!

04

Turn Off the Oven

After one hour, simply turn off the oven. Do not open the door. Leave the roast inside to finish cooking in the residual heat for several hours. It's best to start this early in the morning so it's ready for dinner.

05

Rest and Slice

After several hours, remove the roast from the oven and place it on a cutting board. Slice diagonally against the grain. The center will be a beautiful medium-rare, while the ends will be medium to well done — something for everyone!

06

Make the Perfect Au Jus

Pour some water into the baking dish with all those wonderful drippings. Microwave for several minutes to soften the fond, then scrape it off the bottom and strain. You will have a perfect au jus sauce. Serve alongside the roast with a freshly steamed vegetable and fresh sourdough bread for dipping in the au jus. Family and friends will absolutely love this meal!

Robin's Tips & Variations

  • Choose a boneless, lean cut with no bone, fat, or gristle — sirloin tip and eye of round are ideal.
  • The one-hour full preheat at 500°F is the secret to this recipe. Don't rush it.
  • Never open the oven door during the roasting hour or the resting period — the trapped heat is what cooks the roast perfectly.
  • Starting early in the morning gives the roast plenty of time to finish in the residual heat and be ready by dinner.
  • Slicing diagonally against the grain gives you tender, beautiful slices every time.
  • The pan drippings make an incredible au jus — don't skip this step!

Enjoy every bite!
