Only 5 main ingredients
Minimal prep time
Budget-friendly
Perfect for special occasions
Fall-apart tender beef
Rich, creamy mushroom gravy

Ingredients

3 lbs (1.3–1.5 kg) beef chuck roast
8 oz (225–300 g) fresh mushrooms, sliced
1 (10.5 oz) can cream of mushroom soup
1 packet ranch seasoning mix
1 cup beef broth

Optional:

2 cloves garlic, minced
½ teaspoon black pepper
1 tablespoon butter (for searing)

Instructions

Step 1: Optional Sear for Extra Flavor

For deeper flavor, heat a large skillet over medium-high heat and melt the butter. Sear the beef roast on all sides for about 2–3 minutes per side until browned. This step is optional but highly recommended.

Step 2: Assemble in the Slow Cooker

Place the beef roast in the bottom of your slow cooker. Sprinkle the ranch seasoning evenly over the meat.

In a bowl, mix the cream of mushroom soup and beef broth until smooth. Pour the mixture over the roast.

Top with the sliced mushrooms (and garlic if using).

Step 3: Slow Cook to Perfection

Cover and cook:

On LOW for 7–8 hours
OR
On HIGH for 4–5 hours

The beef is done when it is fork-tender and easily pulls apart.

Step 4: Serve

Once cooked, gently shred the beef or slice it. Stir the sauce slightly so the mushrooms blend into the creamy gravy.

Serve hot with:

Mashed potatoes
Buttered egg noodles
Steamed rice
Crusty bread

Spoon plenty of that creamy mushroom sauce over everything!

Tips for Success

Chuck roast works best because it becomes extremely tender when slow cooked.
Do not open the lid frequently — this releases heat and increases cooking time.
If you prefer a thicker gravy, mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir it in during the last 20 minutes of cooking.

Storage

Refrigerate leftovers in an airtight container for up to 3–4 days.
Freeze for up to 2 months. Reheat gently on the stovetop or microwave.
