What Sets This Pot Roast Apart?
When it comes to a wholesome Sunday dinner, nothing quite beats a classic pot roast! As much as we love our Beef Tenderloin Roast and Pork Roast, a pot roast really knows how to hit the spot on a cool Sunday evening. What is truly outstanding is how easy it is to create a deeply flavorful dish that absorbs all the flavors from the herbs, spices, and broth it’s cooked in, ALL-IN-ONE-POT!
Filling your home with the mouth-watering aroma of rich gravy, earthy vegetables, and tender beef, this Pot Roast can be cooked in three different ways: Slow Cooker, Instant Pot, or Traditional Oven. All methods promise to deliver a dish that is just as delicious. The slow cooking process transforms a tough cut of meat into a tender, juicy masterpiece. Despite its gourmet taste, a pot roast is relatively easy to prepare. It’s a set-it-and-forget-it dish that requires minimal hands-on time, allowing you to focus on other tasks while it cooks to perfection.
Creating Perfect Pot Roast: Key Ingredients

The secret to this Tender Pot Roast lies in its key ingredients. Each one brings something unique to create a deeply flavorful, melt-in-your-mouth dish. Let’s dive into what makes this pot roast recipe truly exceptional:
- Chuck Roast: Choose a well-marbled chuck roast for the best results. The marbling ensures the meat remains tender and juicy, breaking down beautifully during the slow cooking process. Look for a cut that’s around 2-3 inches thick for even cooking.
- Yellow Onions: Opt for fresh, firm yellow onions. They add a natural sweetness and depth to the dish as they cook down. Their flavor is essential to creating a rich and savory gravy.
- Dijon Mustard: Use high-quality Dijon mustard for the best flavor. It adds a subtle tang and complexity, enhancing the overall taste of the pot roast. A little goes a long way in balancing the richness of the beef, or chicken, justy like in this Creamy French Mustard Chicken.
- Balsamic Vinegar: Select a good balsamic vinegar, preferably one that’s aged. Its tangy sweetness adds a unique depth to the pot roast, complementing the savory elements and tenderizing the meat perfectly.
Note: Please see Recipe Card at the bottom for a full list of ingredients and measurements.
Additions And Substitutions
When it comes to Tender Pot Roast, flexibility is key. Even if you don’t have every ingredient on hand, don’t worry—there are plenty of delicious alternatives that will keep the flavors rich and satisfying.
- Any Cut of Beef Roast: Chuck roast is tender, falls apart easily, and is perfect for shredding. Brisket has a lot of connective tissue, making it a fattier cut that becomes super tender while cooking slow but can still be sliced for serving. Round cuts like bottom round or top round are lean and easy to slice.
- Potatoes: Yukon Gold holds up well during slow cooking and absorbs flavors nicely. Red potatoes have a firm texture and are excellent for slow cooking. Peeled Russet potatoes are great at soaking up the broth and spices, making them a versatile option.
- Onions: White onions add an excellent flavor when slow-braising, while yellow onions enhance the overall taste of the pot roast. Both options bring a depth of flavor that complements the meat and vegetables.
Making The Best Beef Pot Roast: Step-By-Step
Ready to create a mouthwatering Tender Pot Roast? Follow these simple steps with images to guide you through the process. You’ll achieve a melt-in-your-mouth roast with rich, savory flavors of garlic, herbs, and vegetables that are sure to impress and delight:

- Season Roast: Season roast with salt and pepper. Heat oil in a large skillet over high heat.

- Sear Roast: Sear on all sides until browned (about 5-6 minutes each side). Transfer roast to a 6-quart slow cooker.

- Add Ingredients: Add onions, garlic, potatoes, carrots, celery, balsamic vinegar, mustard, brown sugar, thyme, and bouillon. Season with salt and pepper. Mix stock with flour and pour into the slow cooker (don’t worry about lumps, they will cook out).

- Cook on Low: Set your slow cooker to the low setting and cook for 8 hours. During this time, the meat will become tender and fall apart effortlessly, while the vegetables will soften and absorb all the delicious flavors from the juices.

- Adjust Seasoning: Taste test and add extra balsamic vinegar, brown sugar, salt, or pepper if needed.

- Serve: Slice the meat, garnish with parsley, and drizzle with gravy.
Alternative Cooking Methods
Instant Pot
- Season roast with a good amount of salt and pepper. Heat oil in the Instant Pot and set to ‘Saute’. When oil is hot, sear on all sides until browned (about 4-5 minutes each side).
- Add the onions, garlic, potatoes, carrots, celery, balsamic vinegar, mustard, brown sugar, thyme and bouillon. Season with salt and pepper to taste. Mix the stock with the flour and pour into the slow cooker bowl (don’t worry about any lumps, they will cook out). Place lid on Instant pot with the steam valve closed.
- Change Instant Pot setting to ‘manual’ mode for 60 minutes on ‘high’ pressure.
- When time is up and the cooker beeps, turn it off and allow pressure to release naturally for 15 minutes. After 15 minutes, use the quick pressure lever to release any remaining pressure. Carefully remove the lid and transfer the roast and veggies to a warm plate.
Oven Method
- Preheat oven to 350°F (175°C). Heat oil in a Dutch oven or heavy-based oven-proof pot over medium-high heat. Season the roast all over with a good amount of salt and pepper. Sear until brown on all sides (about 4-5 minutes each side).
- Transfer the roast to a plate. Sauté onions until transparent, then add garlic and cook for 30 seconds until fragrant. Add the stock and balsamic vinegar to deglaze your pan, scraping up any browned bits. Whisk in the flour and let cook for about 4 minutes (don’t worry about any lumps, they will cook out).
- Transfer the roast back into the pot. Add the potatoes, carrots, celery, mustard, brown sugar, thyme, and bouillon. Season with salt and pepper to taste.
- Bring to a simmer, cover with a lid (or foil), and transfer to the oven. Roast for 3-4 hours until the meat is tender and falling apart. (Check roast after 1 1/2 hours. If the liquid has mostly been absorbed, stir in 1 cup of extra broth and continue cooking.)
- Transfer the roast, carrots, and potatoes to a warm plate. With a spoon, skim the fat off the surface of the cooking liquid. Cut the roast into thick slices, and serve with the vegetables. Pass the pan juices separately.
What To Serve With Pot Roast
Looking for something to serve with your tender pot roast? A slow-cooked beef dish with red wine is a great option if you want something similar but a bit richer. If you’re after a different kind of roast, a baked chicken and rice works well for a more hands-off meal. For sides, garlic bread or a creamy potato dish pair well with the sauce and help round everything out.
Storage, Freezing, and Reheating Instructions.
To Store:
Store leftover pot roast, gravy, and vegetables in an airtight container in the refrigerator for up to 4 days. The flavor continues to develop as it sits, especially with the herbs and sauce.
To Freeze:
Let the beef and gravy cool completely before transferring to a freezer-safe container. Freeze for up to 3 months. It’s best to freeze the chuck roast separately from the vegetables, as potatoes and carrots can soften too much once thawed.
To Reheat:
Reheat gently on the stovetop over low heat until warmed through, adding a splash of broth if needed to loosen the gravy. You can also reheat in the microwave in short intervals, stirring in between to keep the moisture even.
Recipe FAQ’s
It’s optional. You can add carrots peeled or unpeeled, but be sure to cut them into thick chunks to avoid them turning mushy.
If the pot roast is not tender, it may need more cooking time. Continue to cook on low until the meat falls apart easily with a fork.
Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat gently to maintain the tender texture of the meat.
Cook on low for 8 to 10 hours or on high for 4 to 6 hours. Low gives you a better texture. The longer cook time allows the chuck roast to break down properly and become tender.
Low is always the better option. It takes longer, but the result is softer and more consistent. High works if you’re short on time, but the texture won’t be the same.

My boyfriend absolutely raved about this pot roast, said it was one if the best ever. I will definitely make again! The only tweaks I made was I added a splash of red wine while combining the sauce and added Brussels sprouts about an hour before serving. Thanks for a stellar roast on a super chilly, snowy weekend!
I used crock pot method. I used aged balsamic and doubled the garlic. PERFECT RECIPE!
I made this yesterday and my husband and I loved it. Going low carb next week so I think I can make it again without the potatoes and sugar. Thanks for the tasty recipe.
Sounds great, Sharon!
I made it without the potatoes. It was the one ingredient that I didn’t already have.and I like to stay low carb. Came out nice.
I substituted the potatoes for turnips for a low carb option. They held up just as well in my Dutch oven, and it came out perfectly.
I’ve been slow-cooking for years. This recipe, which I made twice this week, is now my *ALL-TIME FAVORITE*!! I am sending the link to all my fam & friends. Amazing!
I agree!
We loved this recipe! The only thing I did differently was after I moved the meat to the crock pot, I put the onions, carrots and potatoes in the beef drippings and sautéed them for about 5 minutes before I put then into the crock pot. This will be our go-to pot roast recipe from now on.
Do you need to mix during the cooking process in the slow cooker?
Only if you would like to. The slow cooker will do the job ;)!!
Made this last night and it was fantastic. This was my second time using my crock pot. The first was ok, and kinda put me off a second attempt, so I’m glad that I found this recipe (and chuck roast on sale). 🙂
I followed the crock pot recipe pretty closely. It took me about 30 minutes in prep time (searing meat, peeling potatoes, chopping veggies). Put the meat into the pot first, then added the veggies and other ingredients Used dried rosemary instead of thyme, and did one yellow and one red onion, and skipped the vegetable stock powder (didn’t have any). And this still turned out great.
Wondering if the stock would have made the sauce thicker, and probably saltier, but I love it just the way it was. I cooked for 7 hours, and the meat definitely fell apart when touched (thought I would need to slice it, but wasn’t necessary).
I was worried that it didn’t have enough liquid, but after about 4 hours, I think the veggies started to sweat and contributed to the sauce.
I mixed the mustard and beef stock together before adding to ensure they were blended.
And I’m looking forward to the leftovers today, the flavors should have had more time to really mix and should be great.
Thanks for a great recipe!
I’m so glad I read this because I was worried there isn’t enough liquid and I didn’t have the vegetable stock.
Made this today in my crock pot, turned out delicious!!! I will definitely make this again.
That is great to hear! Thank you so much! I really appreciate it! XO
Do you use prepared mustard or powdered mustard?
I use prepared mustard.
Waiting on this now! Just for extra flavor, before searing off the meat, i chopped all veggies, threw them on a foil covered cookie sheet, drizzled with olive oil, salt and pepper and threw them under the broiler. Once the meat was seared, the veggies were softened with some caramelized bits. Perfect for added depth! Otherwise, it’s done to the letter.
I’ll write back later with the verdict from the fam!
What was the verdict? 😉
Made this for dinner last night and the family was amazed with it. They loved it and I’m not a cooker…I can cook but I DO NOT like it but I enjoyed the pre time and definitely enjoyed the meal. Thank you for sharing all of your recipes.
