Instructions

Beef Tenderloin Crock Pot Recipe

Step 1: Prepare the Beef

Start by seasoning your beef tenderloin generously with salt and pepper. If you have time, searing the beef in a hot skillet with olive oil for 2-3 minutes on each side will add a delicious crust and enhance the flavors. This step is optional but highly recommended for an extra layer of taste.

Step 2: Layer the Flavors

Place the beef tenderloin in the crock pot. Add the minced garlic, rosemary, and thyme around the beef. Pour in the beef broth and red wine, ensuring the liquid covers about halfway up the side of the beef. This combination will create a rich and aromatic cooking environment.

Step 3: Slow Cook to Perfection

Set your crock pot to low and cook for 6-8 hours, or until the beef is fork-tender. The low and slow method is key to breaking down the fibers in the beef without drying it out, resulting in melt-in-your-mouth tenderness.

Step 4: Rest and Serve

Once cooked, let the beef rest for 10 minutes before slicing. This allows the juices to redistribute, ensuring every bite is moist and flavorful. Serve with the cooking liquid as a natural au jus or thicken it for a more gravy-like consistency.

Tips and Tricks

For an even deeper flavor, marinate the beef tenderloin overnight in the fridge with the herbs and half of the beef broth. When using wine, opt for a dry red like Cabernet Sauvignon for the best flavor profile. If you’re short on time, cooking on high for 3-4 hours can work, but low and slow is always better for tenderness. To thicken the cooking liquid into a gravy, mix 1 tbsp cornstarch with 2 tbsp cold water and stir into the liquid after removing the beef, then cook on high for 10-15 minutes.

Recipe Variations

  • For a smoky twist, add a teaspoon of smoked paprika to the seasoning mix.
  • Substitute the red wine with balsamic vinegar for a tangy flavor profile.
  • Add mushrooms and onions to the crock pot for a hearty, one-pot meal.
  • Use chicken broth instead of beef broth for a lighter taste.
  • For a spicy kick, include a diced jalapeño or a teaspoon of red pepper flakes.

Frequently Asked Questions

Can I use a different cut of beef?

Absolutely! While beef tenderloin is ideal for its tenderness, you can use chuck roast or brisket for a more budget-friendly option. Just adjust the cooking time as these cuts may require longer to become tender.

Is the red wine necessary?

Not at all. The red wine adds depth and richness to the dish, but you can omit it or substitute with additional beef broth or a non-alcoholic red wine alternative without significantly altering the outcome.

How do I know when the beef is done?

The beef is done when it’s fork-tender and easily pulls apart. If you’re unsure, use a meat thermometer; the internal temperature should reach at least 145°F for medium-rare, but slow cooking often brings it well beyond that for ultra-tenderness.

Summary

This beef tenderloin crock pot recipe is a foolproof way to enjoy a luxurious meal with minimal effort. Perfectly tender, richly flavored, and endlessly adaptable, it’s sure to become a staple in your cooking repertoire.
