Sweet Pepper Garlic Butter Beef Brisket Step-by-step instructions

Before you start

Before starting, ensure the brisket is trimmed of excess fat, leaving about 1/4 inch for flavor. Slice the bell peppers into thick strips and the onion into half-moons.

If making homemade compound butter, prepare it ahead and chill until firm. Have a 6-quart slow cooker ready. No other prep is needed—this recipe is truly dump-and-go.

Instructions

Layer and Top

1. 1Layer the Brisket
   Place the trimmed beef brisket flat in the bottom of a 6-quart slow cooker. Press it down gently so it sits evenly in the insert.
   Look for The brisket should lie flat and cover most of the bottom.
   Tip Trim excess fat to about 1/4 inch for the best texture.
2. 2Add Peppers and Onions
   Scatter the thick strips of red and green bell peppers and the sliced sweet yellow onion over the raw brisket, spreading them evenly across the surface.
   Look for The vegetables should cover the brisket in a single, even layer.
   Tip Cut the peppers and onions into similar-sized strips so they cook evenly.
3. 3Top with Cowboy Butter
   Place the four thick medallions of garlic-herb compound cowboy butter on top of the peppers and onions, spacing them evenly over the roast.
   Look for The butter medallions sit visibly on top of the vegetables.
   Tip If using homemade butter, chill it well so it holds its shape.

At this point, the raw brisket sits in the pot with a colorful layer of peppers and onions on top, crowned with butter medallions. The ingredients look fresh and vibrant, and the butter is still firm. This is the easy part—everything is ready to cook.

Slow Cook and Shred

4. 4Cook Low and Slow
   Cover the slow cooker and cook on low for 8 to 10 hours, until the brisket is fork-tender and easily shreds. Do not lift the lid during the first 6 hours. Let it rest for 3 minutes before slicing.
   Look for The meat is done when a fork slides in with no resistance and the fibers pull apart easily.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Cooking on low gives the collagen time to break down for the most tender result.
5. 5Shred the Brisket
   Remove the brisket to a cutting board and let it rest for at least 3 minutes. Using two forks, shred the meat into bite-sized pieces, discarding any large fat pieces.
   Look for The meat should pull apart into long, juicy strands with little effort.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resting the meat helps the juices redistribute, keeping it moist.
6. 6Return to Pot
   Return the shredded brisket to the slow cooker with the peppers, onions, and buttery juices. Stir gently to combine and let it sit on warm for 10 minutes so the flavors meld.
   Look for The meat is coated in the rich gravy, and the vegetables are tender.
   Tip Stir gently to keep the brisket in nice chunks.

After hours on low, the kitchen smells rich and savory. The brisket is fork-tender and shreds easily, with the peppers and onions soft and bathed in a buttery, garlicky sauce. The meat is juicy and the vegetables are sweet and caramelized.

Serve and Enjoy

7. 7Serve Over Noodles
   Spoon the hot brisket and vegetables over warm buttered egg noodles, or serve as desired. Drizzle with extra gravy from the pot.
   Look for The dish is steaming and the gravy is glossy and rich.
   Tip For a low-carb option, serve over cauliflower rice or mashed potatoes.

The shredded beef is piled over warm noodles, glistening with gravy. The peppers and onions add color and texture, and the sauce is thick and flavorful. Each bite is tender, buttery, and satisfying.

Common mistakes

One common mistake is lifting the lid during cooking, which releases heat and extends the cooking time. Another is using a lean cut of beef, which can dry out. Be sure to use a well-marbled brisket or similar cut.

Overcooking can also dry out the meat, so check for doneness at the 8-hour mark. Finally, don't skip resting the meat before shredding—it helps retain juices.

How to tell it’s done

The brisket is done when it is fork-tender: a fork inserted into the thickest part meets no resistance and the meat shreds easily.

The internal temperature should read at least 145°F (63°C) for food safety, but for optimal tenderness, it will likely be higher after hours of slow cooking.

The peppers and onions should be soft and translucent, and the sauce should be rich and buttery. Let the meat rest for at least 3 minutes before shredding.

• Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
