Rosemary-Garlic Roast Beef

This tender and juicy roast looks beautiful when I serve it to guests. It also makes the house smell wonderful as it cooks. I usually serve it with warm French bread and a salad topped with buttermilk dressing. —Brenda Hlivyak, La Center, Washington
  • Total Time
    Prep: 15 min. Bake: 40 min.
  • Makes
    6 servings


  • 4 garlic cloves, minced
  • 1 tablespoon dried rosemary, crushed
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 beef tri-tip roast (2 to 3 pounds)
  • 4-1/2 teaspoons olive oil
  • 12 small red potatoes, quartered
  • 2 medium sweet yellow peppers, cut into 1-inch pieces
  • 1 large sweet onion, cut into 1-inch slices


  • Combine the garlic, rosemary, salt and pepper; set aside 4 teaspoons. Rub the remaining mixture over roast; place in a greased shallow roasting pan.
  • In a small bowl, whisk reserved herb mixture with oil. In a shallow dish, combine the potatoes, yellow peppers and onion; add oil mixture. Toss to coat. Arrange vegetables around roast.
  • Bake, uncovered, at 425° for 30-60 minutes or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°).
  • Transfer roast and peppers to a warm serving platter. Let stand for 10-15 minutes before slicing. Meanwhile, return potatoes and onion to the oven; bake 10 minutes longer or until potatoes are tender.

    I had to substitute the tri tip for a rump roast since my local grocery store didn't carry tri tip and it was still quite tender and delicious!! Wish I had more left over.

    I have made this recipe 2 times. Once for Christmas for the family and once for "just us". The second time I put the meat on the grill and the veggies in a foil pack on the grill. It was just about as good as in the oven. It is pricey but sometimes tri tip is on sale and that is when I buy it.

    This recipe sounds great; I am going to try it very soon; my husband is a great fan of anything with garlic, so I'm sure he will enjoy it!
