Hearty Keto Beef Stew: Your Ultimate Low-Carb Comfort Food for Instant Pot or Stovetop

There’s nothing quite like a warm, comforting bowl of beef stew, especially on a chilly day. But for those following a low-carb or ketogenic lifestyle, traditional stew recipes often come loaded with potatoes and other high-carb vegetables. That’s where our Keto Beef Stew recipe comes in. It delivers all the rich, savory flavors and tender, fall-apart beef you crave, without compromising your dietary goals. This versatile recipe can be prepared effortlessly in an Instant Pot for speed or simmered to perfection on the stovetop for deep, layered flavors.

We’ve meticulously crafted this recipe to ensure maximum flavor with minimal effort. Using humble ingredients like succulent beef chuck roast, vibrant radishes, crisp celery, and earthy mushrooms, seasoned with classic Italian herbs, this stew is a revelation. It’s a complete meal that’s both nourishing and incredibly satisfying, proving that healthy eating doesn’t mean sacrificing taste. Whether you’re a seasoned keto enthusiast or just exploring low-carb options, this beef stew is destined to become a staple in your kitchen.

Why This Keto Beef Stew is a Game-Changer

Many traditional beef stews rely on potatoes and flour-based thickeners, which are off-limits for a ketogenic diet. Our recipe cleverly sidesteps these ingredients, introducing brilliant low-carb alternatives that enhance the stew’s texture and flavor profile. Radishes, often overlooked in stews, transform beautifully during cooking, softening to a texture remarkably similar to potatoes, yet without the carbohydrate load. They absorb the rich broth, adding a peppery zing that mellows into a delightful sweetness.

Beyond its low-carb credentials, this stew is packed with nutrient-dense vegetables like celery and mushrooms, providing essential vitamins, minerals, and fiber. The beef chuck roast, a cut celebrated for its ability to become incredibly tender when slow-cooked or pressure-cooked, provides a robust protein base. The resulting broth, thickened subtly with arrowroot starch (a superior keto-friendly alternative to cornstarch), is velvety smooth and deeply flavorful. It’s a meal that truly nourishes the body while satisfying the soul, making it an ideal choice for healthy family dinners, meal prepping, or simply a cozy night in.

Mastering Low Carb Beef Stew in Your Instant Pot

The Instant Pot is a kitchen marvel, transforming long-cooking recipes into quick, weeknight meals. Our low-carb beef stew is no exception, delivering incredibly tender beef and a rich broth in a fraction of the time compared to traditional methods. Here’s a detailed breakdown of how to achieve Instant Pot perfection:

1. Preparation is Key: Start by gathering all your ingredients. Cut your beef chuck roast into uniform 1-inch cubes. This ensures even cooking. Season generously with salt and pepper. Trim and halve your radishes and slice your celery. Prepare your beef broth and tomato paste mixture. Having everything ready before you start cooking streamlines the process.
2. Browning the Beef for Flavor Depth: This step is non-negotiable for a truly flavorful stew. The Instant Pot’s “Saute” function is perfect for this. Add 1 tablespoon of ghee (or coconut oil) and allow it to shimmer. Brown the beef cubes in batches, ensuring not to overcrowd the pot. Overcrowding lowers the pot’s temperature, steaming the beef instead of searing it. A good sear creates a rich crust through the Maillard reaction, locking in juices and developing complex savory notes that will infuse the entire stew. Cook each side for about 2 minutes until deeply browned. Remove the beef and set aside.
3. Building the Flavor Base and Pressure Cooking: Once all the beef is browned, press “Cancel” on your Instant Pot. Return all the browned beef to the pot. Add the beef broth and tomato paste mixture, the prepared radishes, celery, and Italian seasoning. Stir everything gently to combine. Secure the lid, ensuring the pressure valve is closed. Select the “Manual” or “Pressure Cook” setting and set the cooking time to 25 minutes on high pressure. This short pressure cooking time is enough to break down the tough fibers of the chuck roast, making it incredibly tender.
4. Quick Release and Thickening: Once the cooking cycle is complete, carefully perform a quick release of the pressure. This allows the internal pressure to escape rapidly. Once the float valve drops, you can safely remove the lid. The stew will be liquidy at this stage, so it’s time to thicken it. Ladle out about 1/2 to 1 cup of the hot broth into a separate bowl. Whisk in 1 tablespoon of arrowroot starch until completely smooth, ensuring no lumps remain. Arrowroot is an excellent gluten-free and grain-free thickener, perfect for keto diets, and it provides a clear, glossy finish to your stew.
5. Final Simmer and Mushroom Infusion: Press the “Saute” button on your Instant Pot again. Pour the arrowroot mixture back into the stew along with the halved mushrooms. Stir occasionally and simmer for an additional 10 minutes. During this time, the stew will thicken to a perfect consistency, and the mushrooms will cook through, adding their earthy flavor and soft texture without becoming mushy from prolonged pressure cooking. Once the beef is incredibly tender and the stew has reached your desired thickness, it’s ready to serve.

The Classic Approach: Stovetop Keto Beef Stew

For those who appreciate the slow, steady development of flavors that only stovetop cooking can provide, this low-carb beef stew can be perfectly made in a large Dutch oven or heavy-bottomed pot. While the cooking time is longer than with an Instant Pot, the process is equally straightforward and yields a stew with incredible depth and richness. The gentle simmer allows the ingredients to meld beautifully, creating a truly memorable dish.

1. Initial Prep and Searing: Just like with the Instant Pot method, begin by preparing your beef and vegetables (radishes, celery, mushrooms), and mixing your beef broth with tomato paste. Season your beef chuck roast cubes with salt and pepper. Heat 1 tablespoon of ghee (or coconut oil) in your Dutch oven over medium heat until shimmering. Brown the beef in batches until a deep, flavorful crust forms on all sides – this is crucial for the stew’s overall taste. Remove the browned beef and set it aside.
2. Building the Aromatic Foundation: Add the remaining 1 tablespoon of ghee to the pot. Introduce the radishes, celery, and Italian seasoning. Sauté these vegetables, stirring frequently, for about 3 minutes. This step softens the vegetables slightly and allows them to release their aromatic compounds, forming a fragrant base for your stew.
3. Deglazing and Simmering: Pour the beef broth and tomato paste mixture into the pot. Use a wooden spoon to scrape up any browned bits stuck to the bottom of the pot (the “fond”). These bits are packed with flavor and will dissolve into the broth, enriching it significantly. Return the browned beef pieces to the pot. Bring the liquid to a boil, then reduce the heat to a gentle simmer. Cover the pot and let it simmer for 30 minutes. This initial simmering period allows the beef to begin tenderizing and the flavors to start marrying.
4. Thickening the Stew: After 30 minutes of simmering, carefully remove 1/2 to 1 cup of the hot broth from the stew. Transfer it to a separate bowl and whisk in 1 tablespoon of arrowroot starch until it’s completely smooth and lump-free. This arrowroot slurry will be your natural, keto-friendly thickener.
5. Final Simmer and Perfect Texture: Pour the arrowroot mixture back into the pot, along with the halved mushrooms. Continue to simmer for another 10 minutes, stirring occasionally. During this final stage, the stew will thicken beautifully, the beef will become fork-tender, and the mushrooms will cook to perfection, absorbing the rich flavors of the broth. Taste and adjust seasonings if needed. Serve hot and enjoy the heartwarming goodness of your homemade keto beef stew.

10/10!! It was so good! We aren’t keto so I used carrots. I loved that it didn’t have potatoes. I’ve always felt that potatoes are overpowering in stew. The radishes are perfect! Thank you! Definitely making again!
