Heat up a large skillet on high. Add oil to hot skillet. You want it really hot here to brown or "sear" the beef quickly.
Take a paper towel and make sure you dry both sides of the pot roast. Season with a little bit of salt and pepper. Once the skillet is nice and hot, add the roast.
Using tongs, flip the meat over and sear the other side of the roast for another 2-3 minutes.
Transfer meat to slow cooker. Sprinkle packets of dry ranch dressing and onion soup mixes over pot roast.
Top with a stick of butter then place peppers on and around roast.
Cover and cook on low for 8 hours.
Take two forks and start shredding the meat. Discard any big fatty pieces.
You can skip the browning step if you are in a rush, or just don’t feel like it.
If you prefer, you can cut up the peppers and stir those into the meat mixture for an extra kick of flavor.
One reader suggested that it is delicious on hard rolls with melted provolone or mozzarella cheese. I can tell you, we had a small amount leftover so I ate it on a sub roll the following day for lunch with a slice of mozzarella cheese on top and some sliced peperonicini peppers and it was heavenly.
If you are sensitive to sodium, you could use unsalted butter for this. Be sure to use butter and not margarine. Margarine is basically oil. We did not find this recipe salty at all if you use this exact recipe but be sure to adjust to your preferences.
