Step-by-Step Guide to Making Pot Roast with Garlic Mashed Potatoes

Step 1: Prepare the Pot Roast

First, season the beef chuck roast generously with salt and pepper on all sides. This will enhance the flavor of the roast as it cooks.

Heat 2 tablespoons of olive oil in a large, heavy-bottomed pot or Dutch oven over medium-high heat. Once the oil is hot, sear the beef on all sides until browned. This should take about 4-5 minutes per side. Browning the roast not only locks in flavor but also adds a rich, deep color to the final dish.

Once browned, remove the beef from the pot and set it aside on a plate.

Tip: Searing the beef creates caramelized edges, which intensifies the flavor of the dish. Don’t skip this step!

Step 2: Sauté the Vegetables

In the same pot, with the remaining oil and beef drippings, add the chopped onion, minced garlic, carrots, and celery. Sauté for 5-7 minutes, stirring occasionally until the vegetables begin to soften and the onions turn translucent.

The vegetables will absorb the flavors from the beef drippings, adding depth to the final dish. Make sure to scrape up any browned bits from the bottom of the pot for added flavor.

Tip: Be careful not to burn the garlic. Add it a minute or two after the onions and carrots to avoid overcooking.

Step 3: Combine and Cook the Pot Roast

Once the vegetables are softened, return the seared beef to the pot. Pour in 1 cup of beef broth and 1 cup of tomato sauce, making sure the roast is partially submerged in the liquid.

Add 1 tablespoon Worcestershire sauce, 1 teaspoon dried thyme, 1 teaspoon dried rosemary, and 2 bay leaves. Stir everything together, ensuring that the spices and liquids are evenly distributed.

Bring the mixture to a gentle simmer over medium heat. Once it begins to bubble, reduce the heat to low, cover the pot, and let it cook slowly for 3-4 hours. The longer you cook it, the more tender the beef will become. You’ll know the pot roast is ready when it’s easily shredded with a fork.

Tip: To deepen the flavor of the sauce, you can deglaze the pot with a splash of red wine before adding the broth and tomato sauce. This adds complexity and richness to the dish.

Step 4: Prepare the Garlic Mashed Potatoes

While the pot roast is simmering, it’s time to make the garlic mashed potatoes.

Place the peeled and cubed potatoes in a large pot, cover them with water, and add a pinch of salt. Bring the water to a boil and cook the potatoes for about 15-20 minutes, or until they are fork-tender.

Once cooked, drain the potatoes and return them to the pot. Add 4 cloves of minced garlic, 1/2 cup of milk, and 1/4 cup of butter. Season with salt and pepper to taste. Mash everything together until the potatoes are smooth and creamy.

If you prefer a lighter texture, you can add more milk. For extra smooth mashed potatoes, consider using a potato ricer.

Tip: To prevent lumpy mashed potatoes, make sure the potatoes are fully cooked before mashing. Test them by piercing with a fork; they should break apart easily.

Step 5: Serve the Pot Roast and Mashed Potatoes

Once the pot roast is done and the beef is tender, remove it from the pot and shred it using two forks.

To serve, place a generous scoop of garlic mashed potatoes on each plate. Top the mashed potatoes with shredded pot roast, and spoon some of the sauce and vegetables from the pot over the top. The sauce is rich and flavorful, tying the dish together beautifully.

Cooking Tips for the Perfect Pot Roast

1. Cook Low and Slow

For the most tender, flavorful pot roast, make sure to cook it on low heat for the full 3-4 hours. This slow cooking process allows the collagen in the beef to break down, resulting in a melt-in-your-mouth texture.

2. Use the Right Cut of Beef

Beef chuck roast is the traditional cut for pot roast due to its marbling and tenderness when slow-cooked. However, you can also use other cuts like brisket or round roast, just make sure to adjust the cooking time to ensure the meat becomes tender.

3. Deglaze the Pot for Extra Flavor

After sautéing the vegetables, deglaze the pot with a splash of red wine or balsamic vinegar to lift the browned bits from the bottom of the pot. This step adds complexity and richness to the sauce.

4. Customize the Seasoning

Feel free to adjust the herbs and spices to suit your taste. You can add a dash of paprika, a splash of balsamic vinegar, or even a pinch of red pepper flakes for a bit of heat.

Serving Suggestions

This hearty pot roast pairs beautifully with a variety of side dishes. Here are some ideas to complete your meal:

Steamed green beans or roasted asparagus for a fresh, vibrant side.
A simple green salad with a light vinaigrette to balance the richness of the dish.
Warm, crusty bread to soak up the flavorful sauce.
