Cook Pot Roast in Bag Recipe Like This

Follow these simple steps to create a mouthwatering Pot Roast in Bag:
Step 1: Preheat Your Oven
Start by preheating your oven to 325°F (163°C). This temperature allows the roast to cook slowly, ensuring tenderness.
Step 2: Prepare the Baking Bag
Place the baking bag in a large roasting pan. It’s essential to make sure the bag is secure and won’t tip over during cooking.
Step 3: Season the Roast
Rub the chuck roast with the Bake in Bag seasoning mix from McCormick. Make sure to coat it evenly for the best flavor.
Step 4: Add the Water
Pour 1 cup of water into the baking bag with the roast. This will create a delicious gravy as it cooks.
Step 5: Add Vegetables
If you’re using vegetables, peel and chop them into large chunks. Add them to the bag around the roast. This step is optional, but it adds color and nutrition to your meal.
Step 6: Seal the Bag
Close the baking bag securely with the provided ties. Make several slits in the top of the bag to allow steam to escape during cooking.
Step 7: Roast in the Oven
Place the roasting pan in the preheated oven and cook for approximately 3 to 4 hours, or until the meat is fork-tender. The internal temperature of the roast should reach 195°F (90°C).
Step 8: Rest and Serve
Once cooked, carefully remove the bag from the oven. Let the roast rest for about 10-15 minutes before slicing. Serve with the vegetables and the flavorful gravy that has formed in the bag.
Easy Ingredient Swaps

Not all ingredients are set in stone. Here are some swaps you can consider:
- Use beef broth instead of water for an even richer flavor.
- Swap sweet potatoes for regular potatoes for a different taste profile.
- Incorporate parsnips or turnips for added sweetness and texture.
- Try using a pork roast instead of beef for a different flavor experience.
Notes from the Test Kitchen
- For the best results, choose a chuck roast that has good marbling; this will enhance the flavor and tenderness.
- Don’t skip the resting period after cooking. It allows juices to redistribute throughout the meat.
- Feel free to experiment with different herbs and spices if you want to customize the flavor beyond the McCormick packet.
- This recipe is perfect for meal prep; the flavors often improve after resting in the fridge overnight.
Make-Ahead & Storage
This Pot Roast in Bag Recipe is fantastic for make-ahead meals. You can season the roast and prepare the bag with vegetables up to a day in advance. Just store it in the fridge until you’re ready to cook. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stove or in the microwave, adding a splash of beef broth or water to keep it moist.
Ask & Learn
Can I use a different cut of meat for this recipe?
Yes! While a chuck roast is ideal for pot roast due to its tenderness when cooked low and slow, you can also use brisket or round roast. Just be mindful of the cooking time as it may vary.
What if I don’t have a baking bag?
If you don’t have a baking bag, you can use a covered roasting pan. Just make sure to cover it tightly with aluminum foil to retain moisture.
Can I cook this recipe in a slow cooker?
Absolutely! You can adapt this recipe for a slow cooker. Simply follow the same steps for seasoning and adding water and vegetables, then cook on low for 8-10 hours or high for 4-6 hours.
How do I know when my pot roast is done?
The best way to determine doneness is by using a meat thermometer. You want the internal temperature to reach at least 195°F (90°C) for shreddable, tender meat. If you prefer it sliceable, aim for 180°F (82°C).
