Notes
-
This recipe is sometimes called Mississippi Pot Roast.

The pepperoncini do not make it spicy — they add tang and depth.
-
Butter creates a rich, silky sauce; you may use ½ stick to lighten it.
-
If using salted butter, you may want low-sodium seasoning packets.
Tips
1. Choose the right cut
-
Chuck roast is best.
-
Brisket or bottom round also work but may be less tender.
2. Add vegetables
(Not included in the 5 ingredients, but optional)
-
Add potatoes, baby carrots, or onions under the roast so they cook in the juices.
3. Make gravy
Thicken the juices:
-
Mix 1 tbsp cornstarch + 1 tbsp cold water, whisk in, and heat on high for 10 minutes.
4. Reduce salt
Use half packets or low-sodium alternatives.
5. Freeze leftovers
Freeze up to 3 months. Reheat with a splash of broth.
