Keto Beef Stew Ingredients
Note: Gather these wholesome ingredients for a delicious Keto Beef Stew (Slow Cooker or Oven) that’s sure to warm your heart and satisfy your cravings!
For the Base
• Oil – adds fat for browning meat and prevents sticking; opt for olive or avocado oil for great flavor.
• Beef Stewing Meat (2.5 pounds) – provides a hearty protein base; chuck or round cuts work best for tenderness.
• Salt (1 teaspoon; adjust per broth type) – enhances overall flavor; reduce if using a salty broth.
• Black Pepper – adds seasoning to taste; adjust according to spice preference.
For Flavor
• Yellow Onion (1 small, diced) – offers sweetness and depth to the stew.
• Garlic (2 cloves, sliced) – imparts a savory aroma; fresh is ideal, but powdered can substitute if needed.
• Italian Seasoning (2 teaspoons) – a blend of herbs that adds rustic flavor; feel free to swap with any dried herb mix.
• Tomato Paste (2 tablespoons) – thickens the gravy and enhances color; can be omitted or replaced with tomato sauce if necessary.
For the Veggies
• Beef Broth (2.5 cups) – the stew’s liquid base; homemade or low-sodium store-bought work well.
• Soy Sauce or Liquid Aminos (1 tablespoon) – provides a delicious umami flavor; can be used instead of Worcestershire sauce.
• Radishes (1 pound, halved) – acts as a low-carb substitute for potatoes; white radishes or Daikon are also options.
• Carrots (2 large, thickly sliced) – adds sweetness and texture; can be omitted for stricter carb counts.
• Celery Sticks (5, thickly sliced) – contributes crunch and fresh flavor.
• Mushrooms (8 oz package, sliced) – introduces earthiness and umami; any variety works, swap for other hearty veggies if desired.
• Frozen Peas (3 tablespoons) – brings a pop of color and sweetness; optional for those on stricter diets.
For Thickening
• Glucomannan (2 teaspoons) – serves as a low-carb thickener for the gravy; arrowroot or cornstarch are suitable alternatives.
Step‑by‑Step Instructions for Keto Beef Stew (Slow Cooker or Oven)
Step 1: Brown the Meat
Begin by heating a tablespoon of olive or avocado oil in a skillet over medium-high heat. Once the oil is shimmering, add the beef stewing meat and sear it on all sides for approximately 5-7 minutes until it’s nicely browned. This step enhances flavor, so don’t rush it! Once browned, transfer the meat to your slow cooker or Dutch oven.
Step 2: Sauté the Aromatics
In the same skillet, add the diced yellow onion and sliced garlic, sautéing for 1-2 minutes until they become fragrant and slightly translucent. Stir in the tomato paste and Italian seasoning, allowing the mixture to cook for an additional minute. This creates a flavorful base for your Keto Beef Stew.
Step 3: Deglaze the Pan
Pour in half a cup of beef broth, scraping the bottom of the skillet to lift up all those delicious browned bits. This deglazing step infuses more flavor into the stew. Once incorporated, transfer this mixture into the slow cooker or Dutch oven along with the browned beef.
Step 4: Combine the Ingredients
Add the halved radishes, thickly sliced carrots, celery sticks, sliced mushrooms, and the rest of the beef broth to the slow cooker or Dutch oven. Make sure all the vegetables are well distributed. This colorful medley will make your Keto Beef Stew not only nutritious but appealing to the eye!
Step 5: Cook the Stew
For the slow cooker method, cover and cook on LOW for 6-8 hours or on HIGH for 3-4 hours. If using the oven, preheat to 350°F and cook the stew uncovered for about 2 hours, stirring every 30 minutes to ensure even cooking. Keep an eye on the beef; it should become tender and fork-friendly.
Step 6: Add the Peas
After the cooking time, carefully remove the lid of the slow cooker or oven. Stir in the frozen peas, and let them cook without the lid for an additional 15 minutes in the slow cooker or 5 minutes on the stovetop. This will give your Keto Beef Stew a pop of color and sweetness.
Step 7: Thicken the Gravy
To thicken the gravy, dissolve glucomannan in cold water, stirring to create a slurry. Gradually add this mixture into the stew, stirring continuously until the gravy reaches your desired thickness. This step is crucial for achieving that hearty, comforting texture you crave in a stew.
Step 8: Adjust and Serve
Finally, taste and adjust seasoning with salt and black pepper as needed. Serve your warm Keto Beef Stew in bowls and relish the savory goodness. Pair it with a side of low-carb bread or a fresh green salad for a complete meal that will warm your heart and soul!

Helpful Tricks for Keto Beef Stew

Keto Beef Stew (Slow Cooker or Oven) Recipe FAQs
How do I select ripe ingredients for the Keto Beef Stew?
Absolutely! When choosing your vegetables, look for fresh radishes without dark spots or soft blemishes. For the best beef, choose chuck or round cuts with a nice marbling of fat for flavor. Your onion should feel firm with no soft spots, while garlic cloves should be plump and intact.
What is the best way to store leftover Keto Beef Stew?
To store leftovers, allow the stew to cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to 3 days. Be sure to label with the date to keep track!
Can I freeze Keto Beef Stew? If so, how?
Very! To freeze your stew, portion it into freezer-safe containers or bags, removing as much air as possible to prevent freezer burn. Label each container with the date. It can be stored for up to 3 months. When ready to enjoy, let it thaw overnight in the fridge and reheat gently on the stovetop.
I’m concerned about the glucomannan in the stew—what if I over-thicken it?
Great question! If you find that your stew has become too thick, simply stir in a bit more beef broth or water to loosen it up. For a thicker gravy, gradually add glucomannan after mixing it with cold water, stopping when you hit the desired consistency.
Are there any allergy considerations with this Keto Beef Stew?
Yes, certainly! The recipe contains beef and can include soy sauce or liquid aminos, which might not be suitable for individuals with soy allergies.

What do I do if I don’t have glucomannan?
No worries! If glucomannan isn’t available, you can substitute it with arrowroot or cornstarch, which will also thicken your stew nicely. For cornstarch, mix 1 tablespoon with 2 tablespoons of cold water to create a slurry and add it to the simmering stew until thickened.
