On the busiest weeknights, dinner should practically make itself. This slow cooker keto beef stew is the answer: fall-apart tender beef, silky low-carb vegetables, and a rich, savory broth that tastes like it simmered all day — because it did, while you were doing literally anything else. Fifteen minutes of morning prep, and you come home to a house that smells incredible.
Traditional beef stew leans on potatoes and flour; this version keeps every bit of comfort and drops the carbs. Beef chuck becomes spoon-tender in the slow cooker while releasing collagen that gives the broth its body. Turnips stand in for potatoes with a fraction of the carbs, celery root adds silky texture, and tomatoes, garlic, and thyme build deep, anti-inflammatory flavor.
Keto math stays friendly at about 7 grams of net carbs per hearty bowl, with 30 grams of fat and 36 grams of protein. One pot, zero hovering, and leftovers that taste even better the next day.

Why This Recipe Works
Slow cooking is the ideal technique for beef chuck, a hardworking cut rich in connective tissue. Over 7 to 8 hours of gentle heat, that collagen melts into gelatin, which is what gives the broth its lip-smacking body and the meat its fall-apart tenderness — no flour or cornstarch needed for thickness. Searing the beef first is worth the extra ten minutes: the Maillard reaction creates hundreds of flavor compounds that a slow cooker alone can’t produce, and deglazing the pan captures every browned bit into the stew. Turnips are the potato swap that actually works — after hours of braising they turn creamy and mild, absorbing the broth’s flavor at roughly a quarter of the carbs. Celery root adds a silky, almost buttery texture, while tomato paste contributes umami depth and lycopene, an antioxidant studied for cellular protection.
The anti-inflammatory angle runs through the aromatics. Garlic, thyme, bay leaves, and black pepper all contribute studied plant compounds, and the long, slow simmer extracts maximum flavor from them. Keto-wise, the stew lands near 7 grams of net carbs per generous bowl because every vegetable was chosen for low starch: no potatoes, no carrots-heavy sweetness, no flour. The beef’s natural fats plus olive oil deliver about 30 grams of fat, and 36 grams of protein per serving makes this one of the most satiating meals in a keto rotation. It’s humble food engineered to outperform its effort by a mile.
Ingredients
- 2.5 lb (1.1 kg) beef chuck roast, cut into 1.5-inch cubes
- 2 tbsp (30 ml) olive oil, divided
- 1 tsp (5 g) sea salt, plus more to taste
- 1/2 tsp (1 g) black pepper, plus more to taste
- 1 large yellow onion, diced (about 1.5 cups / 220 g)
- 4 garlic cloves, minced
- 2 tbsp (30 g) tomato paste
- 4 cups (950 ml) beef bone broth, low sodium
- 1 cup (240 ml) dry red wine (optional; adds depth)
- 3 medium turnips (about 1 lb / 450 g), peeled and cut into 1-inch chunks
- 1 small celery root (about 12 oz / 340 g), peeled and cut into 1-inch chunks
- 3 celery stalks, sliced thick (about 1 cup / 120 g)
- 8 oz (225 g) cremini mushrooms, halved
- 2 bay leaves
- 1 tbsp (3 g) fresh thyme leaves (or 1 tsp dried)
- 1 tsp (2 g) smoked paprika
- 2 tbsp (8 g) fresh parsley, chopped, for serving
Step-by-Step Instructions
- Pat the beef cubes very dry and season generously with salt and pepper. Heat 1 tablespoon olive oil in a large skillet over medium-high heat and sear the beef in batches, 2 to 3 minutes per side, until deeply browned. Transfer to the slow cooker.
- In the same skillet, cook the onion in the remaining olive oil for 4 minutes until softened. Stir in the garlic and tomato paste; cook 1 minute more until the paste darkens slightly.
- Pour in the red wine if using (or a splash of broth), scraping up all the browned bits, and simmer 2 minutes. Transfer everything to the slow cooker.
- Add the bone broth, turnips, celery root, celery, mushrooms, bay leaves, thyme, and smoked paprika. Stir gently to combine — the liquid should nearly cover the ingredients.
- Cover and cook on low 7 to 8 hours (or high 4 to 5 hours), until the beef shreds easily and the turnips are completely tender.
- Discard the bay leaves. Taste and adjust salt and pepper. For a thicker broth, mash a few turnip chunks against the side of the cooker and stir.
- Ladle into bowls and top with fresh parsley. Serve hot.
Nutrition & Macros
Estimates per serving for 6 servings (about 1.5 cups each). Omitting the red wine reduces carbs by roughly 1 gram per serving; the alcohol cooks off but trace sugars remain.

Tips & Variations
- Don’t skip the sear — it’s the difference between good stew and unforgettable stew.
- Cut vegetables into uniform 1-inch chunks so everything finishes tender at the same time.
- No wine? Use all broth plus a tablespoon of red wine vinegar for brightness.
- Add a parmesan rind to the slow cooker for incredible savory depth (remove before serving).
- Stir in a few handfuls of kale or spinach during the last 30 minutes for extra greens.
- For a thicker stew, whisk 1/2 teaspoon xanthan gum into a ladle of hot broth and stir it back in.
Storage & Meal Prep
Refrigerate in airtight containers up to 5 days — the flavor genuinely improves by day two as everything melds. Reheat gently on the stove or in the microwave. Freeze in portions up to 3 months, leaving headspace; thaw overnight in the fridge. This is peak meal-prep food: make a full batch Sunday and enjoy effortless keto dinners all week. The turnips hold their texture far better than potatoes would after freezing and reheating.
Why no potatoes in keto stew?
A single cup of potatoes has about 30 grams of net carbs — more than a full day’s keto budget for many people. Turnips deliver a similar creamy, comforting bite at roughly 6 grams of net carbs per cup.
Can I cook it on high to save time?
Yes — 4 to 5 hours on high works, but low and slow gives more tender beef and deeper flavor. If you’re home, low is worth it.
Is beef stew anti-inflammatory?
This version supports an anti-inflammatory pattern: no refined carbs or added sugars, plus garlic, thyme, tomatoes, mushrooms, and bone broth — all associated with beneficial plant compounds and nutrients.
What cut of beef is best?
Chuck roast is ideal — its marbling and collagen become tender and rich over long cooking. Stew meat works too, but avoid lean cuts like sirloin, which dry out.
Can I make this in an Instant Pot?
Yes. Sear using the sauté function, then pressure cook on high for 35 minutes with natural release. Add the mushrooms after pressure cooking to keep their texture.
