I cooked this several weeks ago and became an instant fan; the pepperoncini make it especially tasty but not particularly hot.
Slow-cooker Roasted Mississippi Roast
Adapted from: NY Times Cooking
Serves: 8-10
1 boneless beef chuck roast or top or bottom round roast, 3-4 pds (if you choose to use a bone-in roast add an extra 1 to1 1/2 pds to compensate for the bone)
1-2 teas kosher salt
1 1/2 teas freshly ground black pepper
1/4 c AP flour
2-3 T neutral oil
4 T unsalted butter, cut into 4 pieces, (if you have a fat cap on your roast, you can cut this butter down, or remove the fat cap)
8-12 pepperoncini (I like even more since they didn't seem to retain heat in slow cooker)
2 T mayonnaise
2 teas apple cider vinegar
1/2 teas dried dill
1/4 teas sweet paprika
1 teas buttermilk, optional
chopped parsley, for garnish
Rub the roast with the salt and pepper all over. Then sprinkle the flour over all and rub it into the flesh with your fingers.
In a large sauté pan over medium-high to high, heat the oil until it shimmers and threatens to smoke. Set the roast into the pan and cook on all four sides until you have a well-browned crust. Remove from the pan and put the roast into the slow cooker. Drop in the butter and the pepperoncini peppers and turn on the cooker to low.
Combine the mayonnaise, vinegar, dill, and paprika in a small bowl. Stir in the buttermilk and pour all into the cooker spreading over the roast. Replace the lid and continue cooking for 6-8 hours without disturbing it. I found 6 hours was sufficient. At any rate, after 6 hours take the lid off to see if the roast is easily shredded by pulling it apart with 2 forks. If it isn't tender, replace the lid and continue cooking for another 1-2 hours.
When tender continue shredding and mix with the gravy in the cooker. Top with parsley to garnish and serve with buttered noodles, rice, or potatoes (my preference). I used some of my leftovers for pulled beef sandwiches.
