🥩 Ingredients You’ll Need
For the Pot Roast
3–4 lb chuck roast
2 tbsp olive oil
Salt & black pepper, to taste
1 large onion, sliced
4–5 carrots, cut into chunks
3 garlic cloves, minced
2 cups beef broth
1 tbsp Worcestershire sauce
2 sprigs fresh rosemary
3–4 sprigs fresh thyme
2 bay leaves
For the Gravy

🍳 How to Make the Slow-Cooked Pot Roast
- Sear the Beef
Season the roast generously with salt and pepper on all sides. Heat olive oil in a large skillet or directly in the slow cooker (if it allows browning). Sear the beef 3–4 minutes per side until deeply browned.
👉 This step locks in flavor and gives the gravy that rich, caramelized taste.
- Build the Flavor
Place sliced onions, carrots, and minced garlic in the bottom of the slow cooker. Set the beef on top.
- Add the Liquids & Herbs
Pour in the beef broth and Worcestershire sauce. Add rosemary, thyme, and bay leaves.
Cover and cook on:
LOW for 8–10 hours (best texture), or
HIGH for 4–5 hours
The beef will become fork-tender and incredibly juicy.
🥣 Creamy Homemade Gravy
Once the roast is done, remove the meat and vegetables. Strain 1–1½ cups of the cooking juices.
In a pan, melt butter and whisk in flour to create a roux. Slowly whisk in the hot juices until thickened.
Simmer until your gravy reaches the perfect silky texture.
🥔 How to Make Perfect Mashed Potatoes
- Peel and cut potatoes into chunks.
- Boil until fork-tender.
- Drain and mash with butter, warm milk, salt, and pepper.
For extra luxury, add a spoon of sour cream or a splash of heavy cream.
🍽️ Assembly
Pile a generous serving of creamy mashed potatoes onto each plate.
Top with tender pot roast and drizzle with plenty of the homemade gravy.
