How to Make Crockpot Beef Tenderloin
You can jump to the recipe card for full ingredients & instructions!
- Sear the seasoned tenderloin in a large skillet.
- Transfer the beef to the crockpot and cook on low for 3-6 hours.
- Mix your sauce ingredients in a saucepan and simmer for 1-2 minutes.
- Allow the beef to rest for 10 minutes, then serve with the sauce.
- Beef Tenderloin: A great cut of meat, but the key is to not overcook it, as it can become dry if cooked past medium-rare. You can trim and tie the tenderloin yourself but it is much easier to have a good butcher do it for you!
- Garlic and Rosemary: The perfect complements to beef tenderloin! The key is strong, aromatic flavors, so make sure you go for fresh herbs.
- White Wine Vinegar: The base of béarnaise. It adds a subtle acidity and sweetness. I do not recommend substituting another vinegar.
- Shallot: Adds a subtle onion flavor to the béarnaise. Again, make sure to mince it small! No one wants a big bite of shallot in their sauce.
- Dijon: Adds a bit of zing to the sauce to help cut through the richness. It also helps prevent the sauce from curdling.
- Egg Yolks: Adds richness and helps thicken the sauce.
- Butter: Gives the sauce substance and richness, plus delicious butter flavor! No need to clarify it for this recipe.
- Tarragon: The main flavor in béarnaise. It has a subtle anise flavor and pairs deliciously with beef. Don’t skip it!
Beef tenderloin is widely regarded as the most tender cut of beef. It’s important not to overcook beef tenderloin, though, as it can become tough and dry if cooked past medium-rare. The crockpot is a great way to cook tenderloin low and slow.
Yes! Preheat the oven to 285°F, season the beef, and cook on a rimmed baking sheet for 50-60 minutes, or until the beef registers 115°F internally. Cover tightly with foil and allow it to rest for 10 minutes while you prepare the sauce.
Beef tenderloin is best served at medium-rare or below. Rare beef is usually cooked to 125-135°F, and medium-rare is up to 140°F. Feel free to download my meat temperature chart for easy reference!
The main difference between a hollandaise and a bearnaise is flavor. The base of the sauce is the same, but a Bearnaise sauce includes tarragon and shallots in a wine reduction.
You can serve this delish dish with a multitude of yummy sides. Here are some favorites:

Store leftover crockpot beef tenderloin in an airtight container in the refrigerator for up to 3 days. Store leftover bearnaise sauce in the refrigerator for up to 2 days. Reheat bearnaise sauce gently in a saucepan set over medium-low heat, and whisk in 1 egg yolk to restore the emulsion.
Freeze crockpot beef tenderloin in an airtight container for up to 3 months and bearnaise sauce in a Ziplock bag for up to 1 month. Allow beef and sauce to thaw overnight in the refrigerator before reheating.
Is Your Bearnaise…
- If your bearnaise sauce is not thickening, you likely added the butter a bit too quickly. This is easily fixed, though! Rinse out a mixing bowl with hot water. Put in a teaspoon of lemon juice and a tablespoon of the runny bearnaise sauce. Beat with a wire whisk for a moment until the sauce creams and thickens, then stir back into the runny sauce.
- If the sauce becomes too thick, add 1 tablespoon of very hot water and whisk to combine. Keep adding hot water until you achieve your desired consistency.
- If the sauce seems curdled, use the above instructions for a sauce that is too thin.
