Recipe Highlights
I make this classic for slow Sundays and also for weeknights when I want something unfussy that tastes like I fussed. It is all about building flavor early, then letting time do the heavy lifting. If you have a Dutch oven, perfect. If not, any heavy pot with a lid will do. The beauty of this recipe is how flexible it is. Swap carrots for parsnips, toss in a splash of red wine if you have it, or keep it simple with pantry basics.
What you will need
- 3 to 4 pounds chuck roast or similar well-marbled cut
- Kosher salt and black pepper
- 2 tablespoons oil for searing
- 1 large onion, sliced
- 3 carrots, chunked
- 2 cloves garlic, smashed
- 1 tablespoon tomato paste
- 3 cups beef broth
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried thyme, 1 teaspoon dried rosemary, 1 bay leaf

Directions at a glance
- Pat the roast dry, season well, and sear on all sides until deep brown.

- Cover and braise at 300°F for 3 to 3.5 hours, until fork-tender.

If you want a set-it-and-forget-it version, I also love doing a slow cooker pot roast with gravy. The idea is the same. You are chasing tenderness and rich flavor, whichever path you take.
“I made this for my parents and my dad actually went back for thirds. He is not a leftovers guy, but he asked for a take-home container. That never happens.”
Why it works: you build a browned crust on the beef, layer in aromatics, and braise low and slow so the tough fibers relax. The result is spoon-tender meat and a gravy that tastes like it simmered all day. This is the plate that turns a regular evening into a small celebration.
Expert Tips
Here is how to make your Pot Roast over Mashed Potatoes go from good to unforgettable without stressing yourself out.
Gravy that hugs the potatoes
For a glossy gravy that clings, reduce the braising liquid until it tastes a little intense. Then whisk in a quick cornstarch slurry and simmer just until it thickens. Finish with a tiny knob of butter for shine. If the gravy tastes flat, add a splash of Worcestershire or a few drops of vinegar to brighten it up.
Sear with patience. Let the roast sit out for 20 to 30 minutes so it is not ice cold. Pat it dry. Use high heat and do not rush the browning. That deep crust is the flavor foundation.
Salt at the right time. Season the meat generously, but do your final salt adjust after the gravy reduces. Reducing concentrates salt, so you do not want to overdo it early.
Veggie size matters. Cut carrots into big chunks so they do not turn mushy during a long braise. If you love really soft veggies, toss in a few smaller pieces near the end too. Best of both worlds.
Choose the right potato. Yukon Golds make creamy mashed potatoes that hold their shape under gravy. If you only have russets, that is fine. Just add butter slowly and avoid overmixing to keep them fluffy.
Skim the fat. After braising, spoon off excess fat from the top of the liquid before making gravy. A little fat equals flavor. Too much can feel heavy.
Make-ahead friendly. This dish tastes even better the next day. Refrigerate the pot roast in its liquid, then reheat gently. The mashed potatoes can hold well in a covered bowl over a pot of simmering water, or reheat with a splash of milk.
If you love this style of cozy cooking, try a special-occasion twist like Italian pot roast with Parmesan risotto. Same vibe, new personality.
What Side Dishes Go Well With Pot Roast?
Since Pot Roast over Mashed Potatoes already gives you a hearty base, I like to keep sides fresh, crisp, and green. A simple salad with lemony dressing cuts through the richness. Roasted Brussels sprouts or green beans add color and crunch. Warm dinner rolls are great for sopping up extra gravy. If you want corn, try it creamed or just buttered with salt and pepper.
Craving extra comfort on the side for another night? These deliciously simple stewed potatoes are a classic, with soft, brothy bites that pair up with almost anything.
What Can I Do with Leftover Pot Roast?
Leftovers are basically a gift you gave your future self. Shred the beef and spoon it onto toasted rolls with provolone for quick sandwiches. Make loaded baked potatoes with butter, beef, and a splash of gravy. Stir it into egg noodles like a beefy stroganoff shortcut. Tuck it into quesadillas with cheddar. My personal favorite is a cozy hash with diced potatoes and a fried egg on top.
Storage and reheating
Cool leftovers and store them in an airtight container with some gravy to keep everything moist. They are best within 3 to 4 days. Reheat gently on the stove with a splash of water or broth if needed. Got a little extra mash and gravy? Turn it into a speedy soup night with this creamy idea: swirl them into a base like cream potato soup.
If you are batching this for meal prep, portion the meat and potatoes separately. That way you can use the beef in tacos one night and keep the mashed potatoes ready for a different topping the next.
What Cut of Meat Do You Use for Pot Roast?
For me, chuck roast is king. It has the right balance of fat and connective tissue, which breaks down in the oven and gives you that tender, pull-apart texture. You can also use brisket flat or bottom round, but chuck is the most forgiving and the most flavorful for the price. Look for marbling. That snowflake pattern of fat equals juiciness.
A 3 to 4 pound roast feeds four to six people with leftovers, and it fits nicely in most Dutch ovens. Bone-in or boneless both work, but boneless is easier to slice and shred. If your roast is smaller, start checking for tenderness at the 2.5 hour mark. Do not get hung up on the clock though. When a fork slips in with almost no resistance, it is ready.
Lean cuts like sirloin tip can dry out and come out tough. Save those for faster cooking methods. Pot Roast over Mashed Potatoes really shines when you use a cut built for low and slow cooking, because time and moisture do the magic.
Common Questions
Can I make this in an Instant Pot? Yes. Sear right in the pot, then pressure cook on high for about 60 to 70 minutes with natural release. Reduce the liquid on sauté mode and thicken as desired.
Do I have to sear the meat? You do not have to, but you should. Searing adds big flavor and better color. If you skip it, the dish will still work, but the taste will be lighter.
How do I keep mashed potatoes smooth? Warm the milk or cream before adding, and mash by hand. If you use a mixer, keep it on low and stop as soon as it looks creamy to avoid gluey potatoes.
Can I make it gluten free? Absolutely. Thicken the gravy with cornstarch or arrowroot. Everything else is already naturally gluten free if you use a gluten-free Worcestershire.
What temperature should I braise at? I like 300°F. It is gentle enough to keep the meat juicy, and steady enough to get tender in about 3 hours for a typical chuck roast.
