• Family dinners

And because it only uses three ingredients, it’s budget-friendly too.

3-Ingredient Pot Roast Recipe

Ingredients

• 3 to 4 pound beef chuck roast
• 1 packet onion soup mix
• 2 cups beef broth or water

That’s it. Seriously.

How to Make the Best Slow Cooker Pot Roast

Step 1: Prepare the Beef

Start by placing your chuck roast into the slow cooker. If you want extra flavor, you can quickly sear the meat in a hot pan before adding it to the cooker, but this step is optional.

The roast will still turn out incredibly tender either way.

Step 2: Add the Seasoning

Sprinkle the onion soup mix evenly over the top of the roast. This single ingredient adds so much flavor with almost no effort. It seasons the beef while creating a rich and savory broth as it cooks.

Step 3: Pour in the Broth

Add the beef broth or water around the roast. As the meat slowly cooks, the liquid combines with the natural juices from the beef to create the most delicious au jus.

Step 4: Slow Cook Until Fall-Apart Tender

Cover and cook on LOW for 8 hours or HIGH for 5–6 hours.

By the end of cooking, the beef should be so tender that it easily shreds apart with a fork.

Your kitchen will smell absolutely incredible.

The Secret to Incredible Au Jus

One of the biggest reasons people fall in love with this recipe is the au jus.

As the roast cooks, all the beef drippings mix with the onion seasoning and broth to create a deeply flavorful sauce naturally. No flour. No complicated gravy recipe. No extra work.

The result is a rich, savory liquid that tastes like something from a restaurant.

Pour it over:

• Mashed potatoes
• Rice
• Buttered noodles
• Roasted vegetables
• Toasted bread
• French dip sandwiches

You honestly won’t want to waste a single drop.

Why Chuck Roast Works Best

Chuck roast is perfect for slow cooking because it contains enough marbling and connective tissue to become incredibly tender over time.

Cheaper cuts of beef actually work better in recipes like this because the long cooking process breaks everything down slowly, creating juicy, flavorful meat.

After several hours in the slow cooker, the roast becomes fork-tender and practically melts in your mouth.

Easy Variations

Even though the classic 3-ingredient version is amazing on its own, you can always customize it with extra ingredients if you want.

Some delicious additions include:

• Baby potatoes
• Carrots
• Mushrooms
• Garlic cloves
• Fresh rosemary
• Worcestershire sauce

But honestly? The original version is hard to beat.
