How to Make It
Step 1: Prepare the Slow Cooker
Lightly spray the inside of your slow cooker with cooking spray for easier cleanup (optional but helpful).
Step 2: Add the Roast
Place the chuck roast directly into the bottom of the slow cooker.
Step 3: Mix the Sauce
In a bowl, stir together the cream of mushroom soup and beef broth until smooth. Pour this mixture evenly over the roast.
Step 4: Add the Onion Soup Mix
Sprinkle the entire packet of dry onion soup mix over the top of the roast. No need to stir — it will blend during cooking.
Step 5: Cook Low and Slow
Cover and cook on:
-
Low for 8–9 hours (recommended for maximum tenderness), or
-
High for 4–5 hours if you’re short on time.
The roast is ready when it easily shreds with a fork.
Serving Suggestions
This pot roast creates its own savory gravy, making it perfect for serving over:
-
Creamy mashed potatoes
-
Buttered egg noodles
-
Steamed white rice
-
Roasted vegetables
You can also add carrots and potatoes directly into the slow cooker during the last 4–5 hours for a complete one-pot meal.
Tips for Extra Flavor (Optional)
Even though this is a four-ingredient recipe, you can elevate it further if you’d like:
-
Sear the roast in a hot skillet for 2–3 minutes per side before placing it in the slow cooker for deeper flavor.
-
Add fresh thyme or rosemary for an herbal touch.
-
Stir in a splash of Worcestershire sauce for extra savory depth.
But honestly? It’s delicious even without the extras.
