Preparation instructions
Prepare the beef fillet
1Trim any excess fat from the beef fillet. Pat it dry with paper towels to ensure a good sear later.
Mix the dry rub
2In a small bowl, combine smoked paprika, salt, pepper, onion powder, and dried herbs. Mix thoroughly.
Apply the seasoning
3Rub the olive oil and minced garlic all over the beef fillet. Then, rub the dry seasoning mix evenly on all sides of the fillet.
Sear the beef fillet
4Heat a large skillet or frying pan over medium-high heat. When hot, sear the beef fillet in the olive oil for about 2-3 minutes per side until it forms a brown crust. This locks in the juices and adds flavor.
Set up the slow cooker
5Place the seared beef fillet in the slow cooker. Add the BBQ sauce and beef broth around the meat (not pouring directly on top) to keep it moist.
Slow cook the beef
6Cover and cook on low for 4 hours. The slow cooking at low heat breaks down connective tissue making the meat tender. Optionally, cook on high for 2.5 hours if pressed for time.
Check internal temperature
7Use a meat thermometer to check the internal temperature of the beef fillet. For medium-rare, aim for 135°F (57°C). For medium, 145°F (63°C). The US Department of Agriculture recommends a minimum of 145°F followed by a 3-minute rest for safety.
Rest and serve
8Remove the beef fillet and cover loosely with foil. Rest for 10-15 minutes to allow juices to redistribute. Slice against the grain and serve with additional BBQ sauce if desired.
Cooking Tips
-Use a quality meat thermometer to accurately monitor the internal temperature of the beef for safe and perfect doneness.
-Avoid cross-contamination by washing hands, utensils, and surfaces after handling raw beef.
-If you don’t have a slow cooker, you can cook the beef fillet in a low oven (around 120°C/250°F) covered, for about 3 to 4 hours.
-Feel free to substitute dried herbs with fresh rosemary or thyme for a more fragrant flavor.
-Leftover beef fillet can be chilled and used for quick stir-fries, sandwiches, or salads the next day.

FAQ
What internal temperature should beef fillet be cooked to be safe?
Beef fillet should reach a minimum internal temperature of 145°F (63°C) followed by a 3-minute rest period according to USDA guidelines for safe consumption.
Can I use a different cut of beef for slow cooking BBQ?
Yes, tougher cuts like brisket or chuck roast are excellent for slow cooking and BBQ as they become very tender, but beef fillet will be more tender and lean.
How do I prevent the beef from drying out in the slow cooker?
Adding some liquid like beef broth and BBQ sauce helps maintain moisture, and slow cooking at low heat for a long duration preserves tenderness.
Can I prepare this recipe in advance?
Absolutely, you can season and sear the beef a day ahead, then slow cook it when ready. Leftovers store well refrigerated up to 3 days.
