Ingredients for Buttery Mississippi Pot Roast
For this Buttery Mississippi Pot Roast, we’ll need a simple assembly of hearty ingredients that might already be lurking in your pantry or fridge.
Roast
- Chuck Roast: The star of this dish! Choose a good-quality cut, ideally around 3-4 pounds. Chuck is fantastic because it becomes so tender after slow cooking.
- Butter: About half a stick (1/2 cup). Seriously, the butter is key here for that richness and flavor. You can use unsalted or salted, depending on your preference.
Seasoning Blend
- Mississippi Dressing Mix: This is where the magic happens! It usually has ranch seasoning and some added spices. If you can’t find it, making a homemade version with ranch seasoning, some red pepper flakes, and a pinch of garlic powder works great!
- Pepperoncini Peppers: A jar or about 5-6 peppers. These add a nice tangy flavor and tenderness to the roast. Don’t skip this; it’s a signature flavor!
Vegetables (optional but recommended)
- Potatoes: Yukon Gold or red potatoes, cut into quarters. They soak up the gravy perfectly!
- Carrots: Slice into sticks or rounds, whatever your family prefers.
- Onions: One large onion, chopped. Sweet or yellow will do the job just right.
Stock
- Beef Broth: About a cup for added moisture and depth of flavor.
You can customize your vegetables based on what you have on hand, feel free to toss in other root veggies like parsnips or sweet potatoes!
Let’s Get Cooking!
How to Make Buttery Mississippi Pot Roast
Prepare the Pot Roast (2 minutes): Start by seasoning your chuck roast with a couple of pinches of salt and pepper. This step really builds a delicious base. If you like, you can sear the roast in a hot skillet with a touch of oil for a few minutes until it’s browned all over. But if you’re short on time, you can skip this and go straight to the slow cooker!
Layer in the Slow Cooker (3 minutes): In your slow cooker, place the roast at the bottom. Then scatter in your chopped onions, potatoes, and carrots. Top with the pepperoncini peppers and their juice, and sprinkle the Mississippi dressing mix over the top.
Add the Butter (1 minute): Cut your butter into slices and place it evenly over the roast and vegetables.
Pour in the Beef Broth (1 minute): For extra moisture and flavor, pour in the beef broth. This will create a lovely gravy as it cooks.
Cook the Roast (8 hours on low or 4 hours on high): Cover and set your slow cooker to low for about 8 hours or high for 4 hours. When it’s done, the roast should be fork-tender, and the vegetables will be perfectly cooked.
The Final Touches
- Shred and Serve (10 minutes): Once it’s done cooking, shred the meat with two forks right in the pot. This way, you’ll soak up all that flavorful broth. Give it a gentle stir, and your dinner is ready!
