Slow Cooker Baby Crock Pot Roast Recipe – Tender & Flavorful
If you’ve ever tried making a roast in the oven and ended up with tough meat, this recipe will change the way you cook roasts forever. Using a baby crock pot (small slow cooker) makes the roast incredibly tender, juicy, and flavorful — no knife needed! This is the perfect Sunday dinner recipe, and with the right seasonings, you’ll have enough leftovers to make fajitas, sandwiches, or another easy weeknight meal.
Ingredients
- 2 lb beef roast (or 1–1.5 lb if you prefer smaller portions)
- ½ packet dry Au Jus mix
- ½ packet Hidden Valley Ranch Dressing mix
- ½ stick unsalted butter (about 4 tbsp)
- 1 large onion, thinly sliced
- 1 cup mushrooms (optional, but highly recommended)
- 1 potato, peeled and cut in half (optional – adds heartiness)
- Salt and black pepper, to taste
Cooking Time
- Prep Time: 10 minutes
- Cook Time: 4 hours on Low
- Total Time: 4 hours 10 minutes
Step-by-Step Instructions
Step 1 – Prepare the Roast
- Place the beef roast directly into the bottom of the baby crock pot.
- If the roast is too large, cut it in half. One half can be frozen for a future meal.
Step 2 – Add Seasonings
- Sprinkle ½ packet of Au Jus mix and ½ packet of Ranch dressing mix evenly over the top of the roast.
- Add onion slices and mushrooms on top. These will cook down beautifully into the sauce.
Step 3 – Add the Butter
- Place ½ stick of butter directly on top of the roast.
- The butter melts slowly, making the meat tender and adding a rich flavor.
Step 4 – Slow Cook
- Cover with the lid.
- Cook on Low for 4 hours.
- Do not add any liquid! The roast, butter, and onions will release enough juices to make a flavorful broth.
Serving Suggestions
- As a Classic Roast Dinner – Slice the roast, pour the onion-rich broth over it, and serve with mashed potatoes or roasted vegetables.
- With Gravy – Use the broth to make a thick gravy. Just whisk in a teaspoon of cornstarch mixed with water until the sauce thickens.
- With Leftovers – Turn extra roast into:
- Beef fajitas with tortillas, peppers, and cheese
- Roast beef sandwiches with melted provolone
- A beef-and-vegetable soup for another cozy meal
Expert Tips
- If you don’t like mushrooms or onions, you can skip them, but they add amazing flavor to the gravy.
- For extra seasoning, add garlic cloves, fresh rosemary, or thyme.
- If you want more vegetables, add carrots or baby potatoes to the crock pot while it cooks.
