One of the easiest and most satisfying dinner possible involves a roast of some kind, and roast beef is the classic.  The preparation is usually quite simple, and while it’s in the oven it requires no attention from you.

The only other real factor is measuring the cooking time so that it is cooked to your liking.  You can always put a roast back in the oven, but you can’t un-cook the roast, so err on the side of rarer.   This is especially relevant to the less expensive “roast” cuts, which are not as tender as the pricier tenderloins, but make for a perfectly satisfying and economical dinner.

Also, let your roast sit for about 15 to 20 minutes once out of the oven to reclaim its juices, and during that time it will continue to cook a little more.  So, for rare you want to take it out with an internal temperature of 120°F or 125°, medium rare is 125° to 130°F.  Then, as it sits, the internal temperature will continue to climb a bit, so that when it’s ready to carve, it will be just the way you want it.

I went for a very well-priced boneless beef eye round roast to explore the notion of a economical roast beef.  This simple roast has a 4-ingredient rub (not counting the salt and pepper) that creates a crusty glaze with hearty flavors which permeate the meat, and also fill your kitchen with the smell of a fabulous meal in the making.

Serve roasted potatoes with this, or a baked potato, or mashed potatoes, or some buttered noodles or spaetzle.  Then maybe some roasted carrots or butternut squash to round out the meal.  Pass the Horseradish Sauce on the side, and let everyone take some or not as they please.  Slice the meat very thinly – this helps it in the tenderness department.

Leftovers are sandwiches waiting to be born (don’t forget the sauce!).

  • 2 teaspoons minced garlic
  • 2 tablespoons Dijon mustard, preferably coarse grain
  • 2 teaspoons balsamic vinegar

2. Season the roast well with salt and pepper. Heat 1 tablespoon olive oil in a large ovenproof (preferably cast iron) sauté pan over medium-high heat, and add 1 tablespoon of the oil. When hot, sear the beef on all sides, until nicely browned, about 8 minutes in total.  Transfer the beef to a plate for a few minutes, and pour off most of the remaining fat in the pan.

4. Brush or smear the mixture all over the roast, and return the beef to the skillet fat side down.  Roast in the oven until an instant read thermometer registers 125°F for medium-rare (25 to 30 minutes),  or 130°F for medium (30 to 35 minutes; the temperature will continue to climb for a bit after it is removed from the oven.)

6. While the beef is cooking, make the Horseradish Sauce: in a small bowl blend together the sour cream, horseradish, lemon juice and salt. Thinly slice the meat and serve with the sauce, and the starch of your choice (ideally mashed potatoes!)

    Excellent Recipes!

    1. Maurice Hamp says:

      I love the way the recipes look. I want to cook all of them!

      1. Todd Coleman, the photographer of the book, is a force to be reckoned with! I was thrilled with the way the photos looked.

  4. Jenn says:

    I don’t cook much red meat, and looking to find “my” go to beef recipe, I am trying to decide between this one and your brisket recipe, why would you choose one over the other, pros/cons?

    1. I’d have to say brisket, and here’s why – the leftovers made from the soup turn it into an entire new meal, one that my family looks forward to as much as the brisket itself. Having said that, the roast beef turns into pretty great sandwiches. But there’s just something about that brisket.

  5. Annmarie Grant says:

    This recipe is on my list of things to do with my next paycheck 8) Thanks for an easy and delicious recipe (and I agree that the picture looks absolutely mouthwatering).

    1. It’s not as big a splurge as one might think! But a very impressive dinner. Let me know how it comes out!

  6. Jamie McCowan says:

    Made it and it was delish! The horseradish sauce is mild and for me that is perfect. Will make it again and again.

  7. Mary Anne says:

    Can this be made in crockpot?? Sounds worth the oven effort, just saves so much time in crockpot.

    1. Katie Workman says:

      have not tried it! The texture would be very different, much more like a pot roast, but probably delicious. if you try, let me know!

  8. Jamie says:

    I love horseradish! I was thinking this sauce would pair great with the sous vide recipe I tried for roast beef (http://bit.ly/roastbeefrecipe). This sauce sounds delicious!

  9. Dani says:

    This recipe has officially become my go-to recipe for roasted meat! I’ve made it with several different cuts and it’s always delicious :) thanks for sharing!

    1. Katie Workman says:

      so glad you are finding it a keeper!

  10. Marie says:

    How do u keep the meat warm.. u have it sit out and then slice thin.. put on plate will be cold meat ??

    1. Katie Workman says:

      Yes, it does cool quickly…..if you can warm the plate in a low oven that’s a nice thing to do, but otherwise it’s just warm/room temperature, which is fine!
