Ingredients
You only need five main ingredients:
- 2 pounds beef tenderloin
- 1 can (10.5 ounces) cream of mushroom soup
- 1 packet dry onion soup mix
- 1 cup beef broth
- 2 tablespoons unsalted butter
These five ingredients create a simple, savory sauce that complements the beef without overpowering its natural flavor.
The cream of mushroom soup gives the sauce body and richness, while the onion soup mix adds concentrated savory flavor. Beef broth deepens the sauce, and butter adds a smooth, rich finish.
How to Make Slow Cooker Dad’s Banquet Beef Tenderloin
Step 1: Prepare the Slow Cooker
Lightly coat the inside of your slow cooker with nonstick cooking spray if desired.
This can make cleanup easier.
Step 2: Prepare the Beef
Pat the beef tenderloin dry with paper towels.
If the tenderloin is long, cut it into two pieces if necessary so it fits comfortably in the slow cooker.
Keeping the pieces a similar size helps them cook more evenly.
Step 3: Make the Gravy
In a medium bowl, whisk together the cream of mushroom soup, onion soup mix, and beef broth.
Whisk until the mixture is mostly smooth.
Step 4: Add the Butter
Place the butter in the bottom of the slow cooker.
Add the beef tenderloin on top.
Step 5: Add the Sauce
Pour the mushroom-onion gravy mixture over the beef.
Spread it evenly so the tenderloin is surrounded by the sauce.
Step 6: Cook Carefully
Cover the slow cooker.
Because beef tenderloin is a naturally tender and relatively lean cut, it does not need the long cooking times commonly used for chuck roast.
Cook on LOW and begin checking the internal temperature early, as the exact time depends heavily on the size and shape of the tenderloin and the slow cooker.
For best results, use an instant-read thermometer rather than relying on the clock.
For whole beef cuts, USDA guidance allows a minimum internal temperature of 145°F (63°C) followed by at least a 3-minute rest. If you prefer a different level of doneness, the internal temperature can be monitored to your preferred target.
Step 7: Rest the Beef
Once the tenderloin reaches your desired temperature, carefully remove it from the slow cooker.
Place it on a cutting board and let it rest for at least 3 minutes before slicing.
Resting allows the juices to redistribute and makes the beef easier to slice cleanly.
Step 8: Serve With Gravy
Slice the beef tenderloin into thick pieces.
Stir the gravy in the slow cooker and spoon it over the sliced beef.
For a beautiful presentation, arrange the slices on a serving platter and serve the warm gravy alongside them.
Important Tip: Don’t Overcook Beef Tenderloin
This is the most important thing to remember when making this recipe.
Beef tenderloin is very different from chuck roast.
Chuck roast contains more connective tissue and benefits from several hours of slow cooking. Beef tenderloin is already naturally tender, so excessive slow cooking can result in a texture that isn’t as pleasant.
Use a meat thermometer and start checking the beef early.
The thermometer is much more reliable than simply setting the slow cooker for a long cooking period.
Should You Sear the Beef First?
You can, and it can add extra browned flavor.
If you have a few extra minutes, heat a skillet and quickly brown the outside of the beef tenderloin before transferring it to the slow cooker.
However, searing is optional and adds another step.
If you’re making this as an easy five-ingredient dinner, you can place the beef directly into the crockpot.
Tips for the Best Beef Tenderloin
Use a meat thermometer
This is the most useful tool for this recipe.
Because tenderloin cooks relatively quickly compared with tougher beef cuts, checking the internal temperature helps prevent overcooking.
Don’t rely only on cooking time
Slow cookers vary considerably.
The shape and thickness of your tenderloin also affect how quickly it cooks.
Let the beef rest
Give the cooked beef a few minutes to rest before slicing.
This helps keep the slices juicy.
Slice against the grain
After resting, identify the direction of the muscle fibers and slice across them.
This helps make each bite easier to chew.
Keep the gravy warm
If the gravy becomes too thick after removing the beef, stir in a small amount of warm beef broth until you reach your preferred consistency.
What to Serve With Banquet Beef Tenderloin
This recipe works beautifully with classic steakhouse-style side dishes.
Mashed Potatoes
Creamy mashed potatoes are a natural pairing for the rich beef gravy.
Roasted Potatoes
Crispy roasted potatoes provide a delicious contrast to the tender beef.
Green Beans
Fresh green beans add color and freshness to the plate.
Roasted Carrots
Sweet roasted carrots pair nicely with the savory beef and gravy.
Dinner Rolls
Warm rolls are perfect for soaking up the remaining sauce.
Simple Green Salad
For a lighter option, serve the beef with a crisp green salad and a simple dressing.
Easy Variations
The original recipe stays at five main ingredients, but you can customize it when you aren’t trying to keep the ingredient count exact.
Add Mushrooms
Fresh sliced mushrooms can be added to the gravy for extra earthy flavor.
Add Garlic
Minced garlic works beautifully with beef and mushroom gravy.
Add Fresh Herbs
Thyme, rosemary, or parsley can add a fresh finish.
Add Worcestershire Sauce
A small amount of Worcestershire sauce can deepen the savory flavor of the gravy.
Add Onions
Sliced yellow onions can slowly soften in the sauce and add natural sweetness.
Can I Use Beef Tenderloin Roast?
Yes, a whole beef tenderloin roast can be used.
However, the exact cooking time will depend on its size and thickness.
Always use the internal temperature as your guide.
Can I Use Beef Tenderloin Steaks?
You can, but individual steaks will cook considerably faster than a whole tenderloin.
Check them early and avoid leaving thin steaks in the slow cooker for several hours.
Can I Substitute Chuck Roast?
You can make a similar gravy-style slow cooker beef recipe with chuck roast, but the cooking method changes.
Chuck roast benefits from a much longer cooking time because it contains connective tissue that needs time to break down.
Don’t use the tenderloin cooking guidance for chuck roast.
How to Store Leftovers
Allow leftover beef and gravy to cool before transferring them to airtight containers.
Refrigerate for 3–4 days.
For the best texture, store the sliced beef with some of the gravy.
How to Reheat Beef Tenderloin
Reheat gently.
Place the sliced beef and gravy in a covered skillet over low heat.
Add a small splash of beef broth if the gravy has thickened.
Heat just until warmed through. Avoid prolonged reheating because tenderloin can become dry when overheated.
Can You Freeze Beef Tenderloin?
Yes.
Allow the beef and gravy to cool completely, then place them in freezer-safe containers.
Freeze for up to about 2–3 months for best quality.
Thaw overnight in the refrigerator and reheat gently.
Frequently Asked Questions
Can I cook beef tenderloin on HIGH?
It’s possible, but because beef tenderloin cooks relatively quickly, LOW is generally easier to control. Regardless of the setting, use an instant-read thermometer.
Why shouldn’t beef tenderloin cook all day?
Tenderloin is already naturally tender and relatively lean. Long slow cooking is better suited to tougher cuts such as chuck roast.
How do I know when the beef is done?
Check the thickest part with an instant-read thermometer. For whole beef cuts, 145°F (63°C) followed by a 3-minute rest is the USDA minimum safe temperature.
Can I make the gravy thicker?
Yes. After removing the beef, simmer the gravy gently in a saucepan until it reduces to your preferred consistency.
Can I make this recipe without cream of mushroom soup?
Yes, but the sauce will need to be changed. The cream soup is what gives this five-ingredient version its creamy consistency.
Can I add potatoes?
Yes. Baby potatoes can be added, although additional ingredients will change the original five-ingredient recipe and may affect cooking time.
