Slow Cooker Garlic Butter Beef Roast
Description
Tender, juicy, and incredibly flavorful, this Slow Cooker Garlic Butter Beef Roast is the ultimate comfort-food dinner. A beef roast slowly cooks with plenty of garlic, butter, savory seasonings, and a rich broth until fork-tender. The buttery garlic juices make a delicious gravy for mashed potatoes, rice, or roasted vegetables.
Ingredients
3–4 lb beef chuck roast
4 tbsp unsalted butter
6 cloves garlic, minced
1 cup beef broth
2 tbsp Worcestershire sauce
1 tbsp Dijon mustard
1 tsp Italian seasoning
1 tsp onion powder
1 tsp smoked paprika
½ tsp black pepper
½ tsp salt
1 large onion, sliced
2 tbsp fresh parsley, chopped
Optional: 1 tbsp cornstarch + 2 tbsp cold water for thickening
Instructions
Pat the beef roast dry with paper towels and season all sides with salt, black pepper, onion powder, paprika, and Italian seasoning.
Heat a large skillet over medium-high heat. Sear the roast for 2–3 minutes per side until nicely browned.
Place the sliced onion in the bottom of the slow cooker.
Put the seared beef roast on top of the onions.
Melt the butter and stir it together with the minced garlic, beef broth, Worcestershire sauce, and Dijon mustard.
Pour the garlic butter mixture over the roast.
Cover and cook on LOW for 8–9 hours or HIGH for 4–5 hours, until the beef is fork-tender.
Carefully remove the roast and let it rest for 10 minutes before slicing or shredding.
For a thicker gravy, transfer the cooking liquid to a saucepan. Mix cornstarch with cold water, whisk it into the liquid, and simmer until thickened.
Spoon the garlic butter gravy over the beef and garnish with fresh parsley.

💡 Tips
Chuck roast is ideal because its marbling becomes wonderfully tender during slow cooking.
Don’t skip the searing step—it adds a deep, savory flavor.
For extra garlic flavor, add 1–2 additional cloves during the final hour.
Letting the roast rest before slicing helps keep it juicy.
Q&A
Q: Can I use another cut of beef?
Yes. Bottom round or brisket can work, but chuck roast generally gives the most tender and flavorful result.
Q: Can I add potatoes and carrots?
Absolutely. Add them around the roast at the beginning for a complete one-pot meal.
Q: Can I make this without searing?
Yes, but searing gives the beef a much richer browned flavor.
Q: How do I store leftovers?
Keep the beef and gravy in airtight containers in the refrigerator for 3–4 days.
Q: Can I freeze it?
Yes. Cool the beef completely, portion it with some gravy, and freeze for up to 3 months.
