How to make Instant Pot Mississippi Pot Roast

Step 1: Prepare the Homemade Au Jus Mixture

In a coffee grinder or food processor, combine the beef bouillon granules (or cubes), onion powder, white pepper, garlic powder, and celery salt.
Grind until you have a fine powder.
Transfer the powdered mixture to a bowl, add 1 tsp of parsley, and mix well.
Store the Homemade Au Jus Mixture in an airtight container. You'll need 3 tablespoons for this recipe.

Step 2: Searing the Beef Roast

Turn on your Instant Pot and select the "Sauté" function.
Add 4 tsp of butter and 2 TBSP of oil to the Instant Pot.
Once the butter is melted and the oil is hot, carefully add the beef roast.
Sear the roast on all sides for about 3 minutes per side or until it's nicely browned.
Turn off the Instant Pot.

Step 3: Preparing the Roast

Add 3 tablespoons of the Homemade Au Jus Mixture to the Instant Pot with the seared roast.

Carefully remove the cooked roast from the Instant Pot and place it on a plate.
Use two forks to shred the beef.
Return the shredded beef to the Instant Pot.
Stir in the Corn Starch Mixture (4 Tbsp Corn Starch + 5 Tbsp water) until the liquid slightly thickens.

Step 6: Cooking Potatoes and Carrots

Add chunked potatoes and baby carrots back into the Instant Pot with the remaining gravy.

Step 2: Searing the Beef Roast

Preheat your oven to 325°F (163°C).
In a large oven-safe Dutch oven or roasting pan, melt 4 tsp of butter and 2 TBSP of oil over medium-high heat on the stovetop.
Once the butter is melted and the oil is hot, carefully add the beef roast.

Mississippi Pot Roast Tips and Storage.

Choose the Right Cut of Beef:

When making Mississippi Pot Roast, you can use a bone-in or boneless beef roast. Chuck roast or bottom round roast are excellent choices as they become tender and flavorful when slow-cooked.

Searing the Meat:

Searing the meat before slow-cooking it adds flavor by caramelizing the surface. Don't skip this step, as it enhances the overall taste of the dish.

Homemade Au Jus Mixture:

Making your own au jus mix using the homemade blend mentioned in the recipe adds depth of flavor. It's a great way to control the salt and seasonings to your preference.
Pepperoncini Peppers: The mild, tangy flavor of pepperoncini peppers gives the dish its unique taste. Adjust the number of peppers used based on your preferred level of spiciness.

Corn Starch Mixture:

The corn starch mixture is used to thicken the gravy. Add it gradually until you reach your desired thickness.

Storage:

Refrigerator:

Store any leftover Mississippi Pot Roast in an airtight container in the refrigerator for up to 3-4 days.

Freezing:

If you have prepared a large batch or want to freeze portions for later use, follow these steps:
Allow the cooked Mississippi Pot Roast to cool to room temperature.
Divide it into portion-sized servings.
Place each portion in an airtight freezer-safe container or a heavy-duty freezer bag.
Squeeze out as much air as possible to minimize freezer burn.
Label the containers or bags with the date.

Freeze for up to 3 months.

Reheating: When reheating, you can do so in the microwave for individual servings or on the stovetop in a saucepan for larger quantities. Alternatively, you can reheat it in the oven by covering it with foil and warming it at 325°F (163°C) until heated through.

Gravy Separation:

When reheating, you may notice that the gravy separates or thickens further. Simply add a bit of water or beef broth and stir gently to restore the desired consistency.

Potatoes and Carrots:

If you have leftover roasted potatoes and carrots, store them separately from the roast to prevent them from becoming too soft. They can be reheated in the oven or microwave.

By following these tips and proper storage techniques, you can enjoy the delicious flavors of Mississippi Pot Roast for days to come, whether you're storing leftovers or preparing it in advance for convenient meals.
