There is something deeply comforting about a plate of roast beef, honey-butter carrots, and a cloud of mashed potatoes. It is the kind of dinner that makes a Tuesday feel like a Sunday, and it comes together with a single oven and one pot for the potatoes.

The secret is a two-stage roast: a hot blast to build a browned crust, then a gentle finish so the center stays rosy and juicy. While the beef rests, the carrots roast in the same pan drippings and the potatoes get whipped with warm cream and butter.
Everything lands on the table in about an hour, and the leftovers make some of the best sandwiches you will eat all week. This is the plate to cook when you want people to feel taken care of.

About the Ingredients
2.5 lb (1.1 kg) beef eye of round or top sirloin roast, tied
Ask your butcher to tie it for even cooking, or use a chuck roast for a more fall-apart texture and add 25 minutes of cook time. Look for a roast with a thin, even fat cap.
2 tbsp olive oil
Avocado oil works well at high heat; avoid extra-virgin olive oil if your oven runs hot, as it smokes above 400F (205C).
1 tbsp kosher salt
Diamond Crystal kosher salt is less dense than table salt, so use half the amount if substituting fine table salt.
1 tsp freshly ground black pepper
Fresh-cracked pepper tastes noticeably brighter; pre-ground pepper loses its punch after a few months in the pantry.
1.5 lb (680 g) carrots, peeled and cut into 2-inch lengths
Thick carrots roast more evenly than baby carrots; if using baby carrots, halve them lengthwise so they caramelize instead of steaming.
2 tbsp honey
Maple syrup is a great swap for a vegan version and gives a slightly deeper, woodsier glaze.
3 lb (1.35 kg) Yukon Gold potatoes, peeled and cut into 1-inch chunks
Yukon Golds mash creamier than russets; if using russets, add 2 extra tablespoons of butter to keep them from turning dry.
1/2 cup (120 ml) heavy cream, warmed
Whole milk plus 2 tablespoons melted butter is a lighter substitute that still keeps the mash silky.
6 tbsp (85 g) unsalted butter, softened, divided
Salted butter works too, but then reduce the salt in the potatoes to 1/2 teaspoon.
3 cloves garlic, smashed
Smashing rather than mincing releases flavor slowly and keeps the garlic from burning in the hot pan.
2 sprigs fresh rosemary
Dried rosemary is much stronger; use just 1/2 teaspoon crumbled and add it with the carrots, not the beef.
Tips & Tricks
- Let the roast sit at room temperature for 30 minutes before cooking. A cold roast cooks unevenly, leaving a gray band around the edges.
- Warm the cream and butter before adding them to the potatoes. Cold dairy makes the starch seize and turns the mash gluey.
- Rest the beef for at least 15 minutes under foil. Cutting early lets the juices run onto the board instead of staying in the meat.
- Do not crowd the carrots. Spread them in a single layer so they caramelize at the edges rather than steam.
Pro Tips
Step-by-Step Instructions
1. Heat the oven
Preheat the oven to 450F (230C) and set a rack in the lower-middle position. Pat the beef dry with paper towels and rub it all over with olive oil, then season generously with the kosher salt and pepper.
2. Sear the beef
Heat a large oven-safe skillet over high heat until it just begins to shimmer, about 2 minutes. Sear the roast on all sides for 6 to 8 minutes total until deeply golden brown, then transfer it to a plate.
3. Roast the beef
Return the beef to the skillet and roast at 450F (230C) for 15 minutes, then reduce the heat to 325F (165C) and continue for 25 to 30 minutes, until an instant-read thermometer reads 125F (52C) in the center for medium-rare.
4. Rest the roast
Transfer the beef to a cutting board, tent loosely with foil, and rest for 15 minutes. The internal temperature will climb to about 130F (54C) and the juices will redistribute.
5. Roast the carrots
While the beef rests, toss the carrots with the honey, garlic, rosemary, and 2 tablespoons of the butter in the hot skillet. Roast at 425F (220C) for 20 to 22 minutes, stirring once, until the carrots are fork-tender and the edges are caramelized and glossy.
6. Boil the potatoes
Place the potatoes in a large pot and cover with cold water by 1 inch. Add 1 tablespoon salt and bring to a boil, then simmer for 15 to 18 minutes, until a knife slides in with no resistance.
7. Mash the potatoes
Drain the potatoes and return them to the warm pot for 1 minute to dry. Add the warmed cream, remaining 4 tablespoons butter, and 1/2 teaspoon salt, then mash until smooth and fluffy, about 2 minutes.
8. Slice and plate
Slice the rested beef against the grain into 1/4-inch slices. Spoon the mashed potatoes onto plates, add the carrots alongside, and drape the beef over the top with a spoonful of pan juices.
Delicious Variations
Herb-Crusted Version
Mix 2 tablespoons Dijon mustard with chopped thyme and press it onto the beef before roasting for a tangy, savory crust.
Garlic Mashed Potatoes
Simmer 4 peeled garlic cloves with the potatoes and mash them right in for a deeper, sweeter flavor.
Balsamic Carrots
Swap the honey for 2 tablespoons balsamic glaze and finish the carrots with a sprinkle of flaky salt.
How to Store Roast Beef with Carrots and Mashed Potatoes
Refrigerator
Store the beef, carrots, and potatoes in separate airtight containers for up to 4 days. Keep the pan juices in a small jar to re-moisten the beef.
Freezer
Freeze sliced beef and carrots in a freezer bag for up to 3 months; mashed potatoes freeze well too but may need a splash of cream when reheated.
Reheating
Reheat the beef gently at 300F (150C) for 10 minutes covered with foil, and warm the potatoes and carrots in the microwave with a splash of water.
Frequently Asked Questions
Q: What is the best cut of beef for roast beef?
Eye of round and top sirloin are the best cuts for a classic sliced roast beef because they are lean and slice neatly. Chuck roast also works but needs a longer, slower cook to become tender.
Q: How do I know when roast beef is done?
Use an instant-read thermometer and pull the roast at 125F (52C) for medium-rare, 135F (57C) for medium, or 145F (63C) for medium-well. The temperature will rise about 5 degrees while the meat rests.
Q: Why are my mashed potatoes gluey?
Overworking the potatoes releases excess starch, which makes them gluey. Mash gently by hand and add warm dairy instead of cold, and avoid a food processor or blender.
Q: Can I make this roast beef dinner ahead of time?
Yes, you can roast the beef and cook the carrots up to 2 days ahead and reheat them gently. Make the mashed potatoes fresh the same day for the best texture.
Q: What should I serve with roast beef and mashed potatoes?
A simple green salad, buttered peas, or Yorkshire puddings round out the plate nicely. A spoonful of horseradish cream or grainy mustard is the classic finishing touch.
