Why You’ll Love This Slow Cooker Mississippi Pot Roast

Tender, Fall-Apart Beef With Minimal Prep

First, chuck roast turns wonderfully tender during the long, gentle cooking time. After 8 to 9 hours on low, you can pull the meat apart with two forks.
Also, Slow Cooker Mississippi Pot Roast needs only about 10 minutes of hands-on prep. So, it works well when you want a filling family dinner without spending the evening beside the stove.

Rich, Buttery, and Savory Flavor

As a result, every bite tastes rich without feeling flat or overly heavy.

Homemade Seasoning Without Packets

Instead of seasoning packets, this recipe uses garlic powder, onion powder, parsley, and dill. Therefore, you get plenty of familiar ranch-style flavor from simple pantry ingredients.

Slow Cooker Mississippi Pot Roast Ingredients

You will need:

4 to 4 1/2 pounds boneless beef chuck roast
2 tablespoons olive oil or avocado oil
1 1/2 teaspoons kosher salt
1 teaspoon ground black pepper
1 tablespoon garlic powder
1 tablespoon onion powder
1 tablespoon dried parsley
1 tablespoon dried dill
1/4 cup pepperoncini brine
2 tablespoons cornstarch
1 tablespoon Worcestershire sauce
1 tablespoon tamari soy sauce
6 to 8 pepperoncini peppers
4 tablespoons unsalted butter, cut into pieces

Choosing the Best Chuck Roast

Chuck roast works especially well because its fat and connective tissue soften during slow cooking. Therefore, choose a boneless roast around 4 to 4 1/2 pounds with visible marbling.

Homemade Ranch-Style Seasonings

Garlic, onion, parsley, and dill create a simple ranch-style blend. Also, kosher salt and black pepper season the beef itself before it enters the slow cooker.

Pepperoncini Peppers and Brine

Pepperoncini taste mild rather than notably spicy. In fact, their brine gives Slow Cooker Mississippi Pot Roast its recognizable bright, tangy finish.

Butter, Worcestershire Sauce, and Tamari

Unsalted butter adds richness while giving you better control over salt. Meanwhile, Worcestershire and tamari add savory depth that works beautifully with beef.

How to Make Slow Cooker Mississippi Pot Roast

Season and Sear the Chuck Roast

First, pat the chuck roast dry. Then season it with kosher salt and black pepper.
Next, heat the oil in a large skillet over medium-high heat. Brown the roast for 3 to 4 minutes per side, then transfer it to your slow cooker.

Add the Homemade Seasonings

Combine the garlic powder, onion powder, dried parsley, and dried dill. Then sprinkle the mixture evenly over the roast.

Add the Pepperoncini and Savory Sauce

Whisk the pepperoncini brine, cornstarch, Worcestershire sauce, and tamari until smooth. Next, pour this mixture over the beef.
Then place the butter pieces on top. Also, arrange 6 to 8 pepperoncini peppers around the roast.

Slow Cook Until Fork-Tender

Cover and cook Slow Cooker Mississippi Pot Roast on low for 8 to 9 hours. The beef should feel very tender when you test it with a fork.
Alternatively, cook it on high for 4 to 5 hours. However, I like the gentle low setting when my schedule allows it.

Shred the Beef and Mix It Into the Gravy

Once tender, pull the beef apart with two forks. Then stir the shredded meat directly into the silky cooking gravy so every piece picks up that buttery, savory flavor.

Tips for the Best Mississippi Pot Roast

Should You Sear the Roast First?

Searing remains optional, especially on a rushed morning. However, those browned edges add deeper beef flavor to the finished dish.
So, I sear whenever I have the extra few minutes.

Why You Don’t Need to Add Beef Broth

You do not need extra broth for Slow Cooker Mississippi Pot Roast. As it cooks, the chuck roast releases plenty of flavorful liquid.
Therefore, adding a large amount of broth can make the gravy thinner than you want.

How to Make the Gravy Thicker

First, remove the cooked beef. Then whisk another 1 to 2 tablespoons of cornstarch into the slow cooker liquid.
Next, cook the gravy for 5 to 10 minutes until it reaches the thickness you like. Then return the shredded beef.

What to Do if Your Pot Roast Won’t Shred

If your roast still feels tough, it usually needs more cooking time. So, cover it again and cook for another 30 to 60 minutes.
Then check it with a fork. Properly cooked chuck roast should pull apart with little effort.
