Grandma doesn’t fuss. She just knows.
And when she says this is “the most tender beef she’s ever tasted,” you listen.
This 4-ingredient slow cooker pot roast is the ultimate Midwestern comfort classic: a chuck roast, onions, beef broth, and a packet of dry onion soup mix. That’s it. No searing. No fancy steps. Just set it and forget it—and come home to beef so tender it melts at the touch of a fork, bathed in a rich, savory gravy that tastes like it simmered for days.
Why This Recipe Works (And Why Grandma Swears By It)
Fork-tender beef—no chew, no effort, just pure comfort
10-minute prep, then hands-off cooking
Budget-friendly—feeds 6–8 for under $20
One-pot wonder—minimal cleanup
Uses a pantry hero: dry onion soup mix = deep umami flavor in seconds
“It’s not fancy—but it’s the kind of meal that makes you sigh with relief.”
Ingredients You’ll Need
(Serves 6–8)
3–4 lb boneless beef chuck roast (well-marbled)
1 large yellow onion, sliced into rings
1 (1 oz) packet dry onion soup mix (like Lipton)
1½ cups beef broth (low-sodium recommended)
Pro Tip: Don’t skip the marbling—fat = flavor + tenderness!

Step-by-Step Instructions
1. Prep the Slow Cooker
Place sliced onions in the bottom of a 6-quart slow cooker.
Set the chuck roast on top (no need to sear!).
2. Add Flavor & Liquid
Sprinkle the entire packet of dry onion soup mix evenly over the roast.
Pour beef broth around the sides (not directly on top—this keeps the seasoning in place).
3. Cook Low & Slow
Cover and cook:
LOW for 8–10 hours, or
HIGH for 5–6 hours
The longer it cooks, the more tender it becomes.
4. Rest & Serve
Turn off slow cooker; let roast rest 15 minutes.
Slice or shred the beef—it should pull apart effortlessly.
Spoon onions and glossy gravy over each portion.
Serving Suggestions
Classic pairing: Creamy mashed potatoes or buttered egg noodles
Lighter option: Fluffy rice or quinoa
Veggie balance: Steamed green beans, roasted carrots, or a crisp arugula salad
Don’t waste a drop: Serve with crusty bread for mopping up every last bit of gravy
Wine pairing: Medium-bodied red like Merlot or Cabernet Franc
Pro Tips for Success
No onion soup mix? Make your own:
→ 3 tbsp dried minced onion + 2 tsp beef bouillon + ½ tsp onion powder + ¼ tsp parsley
Make it gluten-free: Use GF onion soup mix or homemade blend
Freeze leftovers: Portion beef + gravy in freezer bags—reheat for quick meals
Boost flavor: Add 2 garlic cloves or a bay leaf to the slow cooker
FAQs: Your Questions, Answered
Q: Can I use a different cut of beef?
A: Chuck roast is ideal—it has fat and connective tissue that melt into tenderness. Brisket flat or round roast also work.
Q: Why is my gravy thin?
A: Remove beef, then simmer gravy on HIGH (uncovered) for 20–30 mins to reduce. Or mix 1 tbsp cornstarch + 2 tbsp water; stir in.
Q: Can I prep this the night before?
A: Yes! Assemble (uncooked) in the slow cooker insert; refrigerate overnight. Add 30 mins to cook time.
Q: Is the sodium high?
A: Onion soup mix is salty—use low-sodium broth and taste before adding extra salt.
