Step by Step Instructions

Preheat the oven to 400F. Heat olive oil in a large Dutch oven set over medium-high heat. Season the roast with salt and pepper, then sear it on all sides until nicely browned. Remove from the heat.

Tuck the onion, potatoes, and carrots under and around the chuck roast.

In a bowl, whisk together the soups, water, and soup mix until well combined, then pour over the roast.

Place the lid on top of the Dutch oven and place in the oven. Cook for 20 minutes at 400F, then reduce the oven to 325F, and continue roasting for another 4-5 hours, until the beef pulls apart easily with a fork. Internal temperature should reach a minimum temperature of 145°F (63°C)

Remove the Dutch Oven and allow the to rest, with the lid on, for 10 to 15 minutes.

Transfer the roast to a serving plate, garnish with herbs as desired, and serve with the vegetables and gravy.

Expert Tips

As roasts are a thicker cut of meat, allow to sit for 30-40 minutes at room temperature to promote even cooking and fork tender, juicy meat.

Generously season your meat on both sides with salt and pepper before searing/browning. For the best results, season the night before. By doing this, you are essentially creating a dry brine, enhancing the flavor and tenderness.

Always brown your roast on all sides, as this will enhance the beef flavor and create delicious brown bits.  

Once fully cooked, remove it from the oven and allow it to rest for 10-15 minutes with the lid on.

How best to serve

The beauty of this recipe, is that you already have a side dish and gravy prepared.

Here are some other suggestions:

• Egg noodles
• Ancient grains, such as millet or quinoa.
• Traditional cornbread or Keto Cornbread.
• Rice
• Mashed Potatoes - this recipe already calls for potatoes, but you can leave them out and make mashed potatoes instead.
• Fresh salad greens with sliced avocado.
• Broccoli salad
• Green beans
• Asparagus

Storage & Reheating Instructions

Store your leftover pot roast in an airtight container and follow these tips:

• Allow to cool completely to room temperature before transferring it to a storage container. 
• Store with its gravy.
• Refrigerate for up to 4 days
• Freeze for up to 60 days, wrapped in plastic wrap and placed in a freezer safe container or a freezer bag. Remove as much air as possible from the freezer bag when packaging before sealing the bag. 

When removing your leftovers from the freezer, always allow your pot roast to thaw in the refrigerator overnight before reheating. To reheat leftover vegetables, add them in ⅔ through your reheating method.

In the oven: To maintain the best taste and texture, reheat in an oven safe dish with 2-3 cups of broth, red wine, or water at 350F for 35-40 minutes or until heated through (internal temperature of 145F). Use a dish with a lid, or cover your dish with foil to retain the moisture in the meat. Make sure your oven is preheated. Fresh vegetables can be added at the start of cook time or leftover cooked vegetables can be added the last 10-15 minutes. 

On the stovetop: For a quicker method, your pot roast can be reheated on the stovetop. Place your leftovers in a saucepan or deep skillet with enough broth or liquid to partially immerse your meat, as your roast will absorb the liquid. Cover and heat over medium for 10-15 minutes or until heated through. Add any leftover vegetables in the last 5 minutes.

In a crockpot: If you have the time, your pot roast can be reheated in a crockpot. Make sure to fill enough liquid in the crockpot to cover the meat. Cook on low for 2-4 hours ensuring meat is heated through (145F with a meat thermometer).   

Microwave: In a pinch you can reheat using a microwave. It is best to cut or separate the meat with this reheating method. Add liquid (broth, red wine or water) to a microwave safe dish and reheat at 50% power for 60 seconds. Stir, and heat for one or two more 20 second bursts until heated through. Handle with care - the dish will be hot!

What is the best cut of beef for pot roast?

Chuck, Brisket, and Bottom Round are the best cuts to create a rich flavor in this recipe. 

Chuck roast  - "Our favorite for pot roast" is a center cut from the shoulder that offers a rich beefy flavor and is perfect for slow cooking. It has nice marbling "fat" throughout, which helps make it tender and flavorful.

Bottom Round roast - a leaner cut from the rump and hind legs, another cut that is ideal for slow cooking methods. 

Brisket - a tough, primal cut of beef, fatty and filled with collagen and meaty flavor - taken from the lower breast. This cut is ideal for smoking, braising, or the crockpot.
