Before you start
Before starting, slice the bell peppers into thick strips and the onions into half-moons. Cut the butter into small pats and measure the gravy. If using a homemade gravy, prepare it ahead of time.
Place the roast in the slow cooker and layer the vegetables on top. Pour the gravy over everything and dot with butter. No need to brown the meat first—the slow cooker will develop plenty of flavor. Have tongs and a serving spoon ready for later.
Ingredients at a glance (7)
- 3 1/2 lb beef bottom round roast
- 2 red bell peppers, sliced into thick strips
- 2 green bell peppers, sliced into thick strips
- 2 sweet yellow onions, sliced
- 2 cups rich brown gravy
- 4 tbsp unsalted butter, cut into pats
- 6 toasted brioche slider buns, for serving
Instructions
Layer and Pour
- Layer the Roast and VegetablesPlace the beef bottom round roast in the center of a 6-quart slow cooker. Scatter the sliced red and green bell peppers and the sliced sweet yellow onions over and around the roast, creating an even layer. The vegetables will soften and release their juices as the roast cooks, so there is no need to stir or brown the meat first.Look for The roast sits snugly in the crock, surrounded by bright pepper and onion strips.Tip For deeper flavor, sear the roast in a hot skillet for 2 minutes per side before adding it to the slow cooker.
- Pour the Gravy and Add ButterPour the rich brown gravy evenly over the roast and vegetables. Dot the top of the roast with the pats of unsalted butter. The butter melts into the gravy during cooking, adding richness and helping to create a glossy, silky sauce.Look for The gravy covers the roast and peppers, with butter pats melting on top.Tip Use a good-quality store-bought gravy or make a quick homemade version with beef broth and a roux.
At the end of this phase, the slow cooker contains a neat pile of raw beef, peppers, onions, and butter, all coated in brown gravy. The colors are vibrant—deep red, green, and yellow against the dark gravy. The butter pats sit on top, beginning to melt. The aroma is savory and slightly sweet, with a rich beefiness from the gravy. Everything is ready to cook.
Slow-Cook and Rest
- Slow-Cook Until Fork-TenderCover the slow cooker and cook on low for 8 to 10 hours, or on high for 4 to 5 hours, until the roast is fork-tender. The meat should shred easily with a fork and the peppers and onions should be very soft. The gravy will have deepened in color and flavor as the beef braises. Let it rest for 3 minutes before slicing.Look for The liquid is bubbling gently and the meat yields easily when pierced with a fork.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Do not open the lid during the first 6 hours of cooking—the heat escapes and slows the cooking.
- Rest the RoastTurn off the slow cooker and let the roast rest in the cooking liquid for at least 3 minutes before shredding. This allows the juices to redistribute throughout the meat, keeping it moist and flavorful. Use tongs to transfer the roast to a cutting board if you prefer to shred it there, or shred it directly in the slow cooker.Look for The roast rests in the hot gravy, steam rising from the surface.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip A longer rest—up to 15 minutes—makes the meat even more tender.
After 8 to 10 hours on low, the kitchen smells intensely of braised beef and sweet peppers. The gravy is a deep mahogany color, and the surface bubbles gently. The roast is visibly shrunken and tender, with edges that flake easily. The peppers and onions have collapsed into soft, silky strands. The meat rests in the hot liquid, releasing steam and ready to be shredded.
Shred and Serve
- Shred the Beef and Combine with VegetablesShred the beef with two forks, removing any large pieces of fat. Return the shredded meat to the slow cooker and stir gently with the peppers, onions, and gravy until everything is well combined. The peppers and onions should be soft and sweet, having absorbed the rich beef flavor.Look for The beef pulls apart into tender strands, coating with glossy gravy.Tip If the gravy seems thin, mix 2 tablespoons cornstarch with 2 tablespoons cold water and stir into the pot, then cook on high for 10 minutes.
- Serve on Toasted Brioche BunsToast the brioche slider buns until golden. Pile a generous portion of the shredded beef and peppers onto the bottom half of each bun, then spoon extra gravy over the top. Set the top bun in place and serve immediately, with extra gravy on the side for dipping.Look for The buns are toasted and the beef is piled high, dripping with gravy.Tip For a fork-and-knife meal, skip the buns and serve the roast over mashed potatoes or egg noodles.
The shredded beef is coated in glossy gravy, with soft peppers and onions mingled throughout. The mixture is moist and fragrant, with a rich, savory aroma. The toasted brioche buns are golden and slightly crisp.
When the beef is piled onto the buns and topped with extra gravy, it looks irresistible—tender strands of meat, sweet peppers, and a sauce that glistens. The first bite is juicy and deeply satisfying.
Common mistakes
One common mistake is lifting the lid too often to check on the roast. Every time the lid is opened, heat escapes and adds 20 to 30 minutes of cooking time. Another pitfall is using a lean cut without enough fat; bottom round needs its marbling to stay moist.
Avoid adding too much liquid—the roast and vegetables release their own juices, so the gravy should not be watery. Also, do not shred the beef too early; it needs the full cooking time to become tender.
How to tell it’s done
The roast is done when it is fork-tender, meaning a fork inserted into the thickest part twists easily and the meat begins to shred.
The internal temperature should reach at least 145°F (63°C) for whole-cut beef, but because it is cooked low and slow, it will likely be higher—around 190°F to 205°F (88°C to 96°C)—which is ideal for breaking down collagen. The peppers and onions should be very soft, and the gravy should be thick and glossy.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
