Beef Shank Pot Roast with Olive Oil Mashed Potatoes

It’s finally starting to feel like fall here in Michigan, and I’ve been craving a cozy, home-cooked meal. Between launching my 2027 planners and traveling, this past month has been full, and I haven’t spent as much time in my kitchen as I usually do. I’ve missed it.

Today, the sun was shining, there was a cool breeze coming through, and it felt like the perfect day to slow down and spend some time cooking. We also all woke up feeling a little under the weather, which made a warm, comforting dinner sound even better.

I had some big pieces of beef shank in the freezer, so I decided to turn them into a beef shank pot roast with onions, garlic, and colorful carrots. While the beef cooked low and slow in the oven, I made really simple mashed potatoes with olive oil to serve alongside it and soak up that savory sauce. Just the kind of dinner I wanted after a busy few weeks.

Watch How I Make This Beef Shank Pot Roast

What is beef shank

Beef shank comes from the leg and is a cut that benefits from slow, moist cooking. Braising means cooking it gently in a covered pot with liquid until it becomes tender enough to pull apart with a fork.

For this recipe, keep the shanks in large pieces. The thickness of your pieces matters, so use tenderness as your guide instead of relying only on the clock.

Ingredients you will need

• Beef shanks: The large pieces are the starting point for this pot roast. Use thawed shanks so you can dry and brown the surface.
• Salt, black pepper, garlic powder, and paprika: A simple seasoning mixture for the meat.
• Olive oil: For browning the beef.
• Onion: Cut into thick, petal-like wedges.
• Garlic: Roughly crush the cloves for the braising pot.
• Tomato paste: Cook it briefly with the aromatics to deepen its flavor.
• Beef broth: The braising liquid and base of the sauce.
• Carrots: I used thin, colorful carrots and left them whole. Cut larger carrots into thick pieces.
• Demi-glace: I also added a few tablespoons demi-glace to the pot.

For the mashed potatoes, you will need potatoes, whole peeled garlic cloves, salt, and olive oil.

Kitchen Tools I Used

Here are the kitchen tools I used to make this beef shank pot roast and the olive oil mashed potatoes:

• Dutch oven: For browning the beef on the stovetop, then transferring it to the oven to cook low and slow.
• Chef’s knife: For slicing the onion and prepping the vegetables.
• Cutting board: For the vegetable prep.
• Tongs: For turning the beef as it browns and transferring it out of the pot.
• Saucepan: For boiling the potatoes and garlic together.
• Potato masher: For mashing the cooked potatoes and garlic before stirring in the olive oil.

You don’t need these exact brands to make the recipe. For the beef, use a heavy, oven-safe pot with a tight-fitting, oven-safe lid.

How to make beef shank pot roast

Season and brown the beef

Preheat the oven to 325°F, or about 160°C.

Pat the beef shanks dry, then season with salt, black pepper, garlic powder, and paprika.

Heat the olive oil in a large oven-safe pot or Dutch oven over medium-high heat. Brown the beef on the exposed meat surfaces, working in batches if needed so the pot isn’t crowded. Transfer the browned shanks to a plate.

Cook the onions and garlic

Add the onion wedges to the same pot and cook until they start to soften, about 3–5 minutes. Add the crushed garlic toward the end and stir until fragrant.

Stir in the tomato paste and cook for another 1–2 minutes, stirring so it darkens slightly without burning.

Add the broth and carrots

Pour in a little of the beef broth and scrape up the browned bits from the bottom of the pot. Add the remaining broth and the demi-glace, stirring to combine.

Return the beef and any collected juices to the pot, then tuck the carrots around the meat. Bring the liquid to a gentle simmer.

The broth should come partway up the shanks. The amount needed can vary with the width of your pot and the size of the meat.

Cover and braise

Cover tightly and transfer to the oven. Allow approximately 3–4 hours, checking for tenderness and adding a little broth if the pot is getting dry. Very thick pieces may take longer.

The beef is ready when a fork slides in easily and the meat pulls apart with little resistance. If it is still firm, cover and continue cooking, checking again in about 30 minutes.

Carrots added at the beginning will become very soft. If you prefer carrots with more texture, you can add them during the final 45–60 minutes instead; that is an optional variation on how I made this batch.

Olive oil mashed potatoes

While the beef finishes cooking, place the potatoes in a saucepan. Cut the potatoes into evenly sized pieces if needed, cover with cold water, and add salt.

Bring to a boil, then reduce to a steady simmer. Cook until the potatoes are easily pierced with a fork. Drain well, then mash the potatoes together. Stir in olive oil and taste for seasoning.

If you want a softer consistency, reserve a little of the potato cooking water before draining and stir it in a splash at a time. This is an optional adjustment.

Spoon the beef, carrots, and braising sauce over the mashed potatoes to serve.

Why I like this kind of dinner

As a dietitian and a busy mom, I like meals that bring a few simple components together on one plate. Here, that’s beef, potatoes, and carrots, with the cooking liquid tying everything together.

There is some work at the beginning, especially browning the meat, but most of the cooking time is hands-off. That gives me time to make the potatoes while dinner finishes in the oven.

Tips for tender beef shanks

• Give the meat space when browning. Cook in batches if needed.
• Keep the lid on during braising. A tight lid helps retain the moisture the beef needs.
• Check the liquid level. Add broth if the pot is getting dry.
• Cook to tenderness. Large shanks may need more time than thinner cuts.
• Taste the sauce before adding more salt. Broth and demi-glace both contribute seasoning.
• Expect a braising sauce. There is no flour or starch thickener added here. If you want a more concentrated sauce, remove the tender beef and carrots and briefly simmer the liquid uncovered, tasting as it reduces.

Frequently asked questions

Can I use chuck roast instead

Chuck roast is another option for a braised dinner, but its cooking time and yield will differ from large beef shanks, especially if the shanks are bone-in. For the cubed chuck version, use the recipe in my fall meals post.

Why are my beef shanks still tough

They may need more time. If the meat is still firm and the pot has enough liquid, cover it and continue braising until it pulls apart easily. Check that the lid is secure and the liquid has not cooked away.

Can I leave the carrots whole

Yes. Thin carrots can stay whole after washing and trimming. Cut thicker carrots into large pieces. Carrots cooked alongside the beef for the full braise will be very soft.

Do I have to cook the potatoes separately

For this version, yes. Cooking them separately lets you mash them with the softened garlic and olive oil, then spoon the beef and sauce over the top.

Storage and reheating

Divide leftovers into shallow containers and refrigerate within two hours of cooking, or one hour if the temperature is above 90°F. Keep the refrigerator at 40°F or below and use leftovers within 3–4 days.

Reheat the beef with some of its sauce until it reaches 165°F. Reheat the mashed potatoes separately, adding a little water if needed, and bring them to 165°F as well.

For longer storage, freeze the beef in portions with its sauce. Thaw in the refrigerator before reheating.
