Beef stew is one of my all-time favorite childhood comfort foods so I gave it a bit of a metabolic makeover. Between my husband Ryan’s pre-diabetes and managing my own hormonal health, I wanted to figure out how to make it more blood sugar friendly. It took me five rounds of testing, but I finally cracked the code.
Nutritional Perks in this Recipe
It’s a meal that captures what we love about traditional beef stew and puts a functional nutrition spin on it:
- Turnips replace potatoes - significantly lower glycemic index while maintaining that satisfying starchy texture, plus they're rich in vitamin C and fiber for immune support
- High protein content from chuck beef helps slow glucose absorption, keeps you fuller longer, and supports muscle maintenance and repair
- Fiber-rich vegetables (carrots, green beans, celery) support steady blood sugar levels while promoting digestive health and heart health
- No flour or cornstarch thickeners - naturally thickened by blending vegetables instead of adding refined starches, keeping it nutrient-dense
- Flavorful aromatics - garlic, onions, and tomato paste add depth while providing beneficial plant compounds
- Balanced macronutrients - the combination of protein, fats, fiber and complex carbs helps blunt blood sugar spikes while providing sustained energy
- Perfect for meal prep - having blood sugar-friendly leftovers ready makes it easier to avoid less healthy convenience options while saving time and money
Let's Talk Turnips: The Secret Potato Swap
Never cooked with turnips? You're not alone! These white and purple root vegetables might look unfamiliar, but I’m a major fan.
After hours of slow cooking, turnips are just like potatoes. I served this stew to potato lovers (including my own family) and they honestly can't tell the difference in this application.
Why turnips work so well in stew
- Mild, slightly sweet flavor (not "earthy" like you might expect)
- Absorb all the rich, savory broth flavors
- Develop the same tender, fork-tender texture as potatoes
- Fraction of the blood sugar impact
Shopping Tip
Look for turnips that feel firm and heavy, about tennis ball size or larger. Don't be intimidated by the purple tops. Just peel like a potato and cut into chunks.
Step by Step Visual Instructions
A little bit of prep work means a whole lot of flavor come dinner time. Let's make some stew.
Step 1: Season and sear the meat in a skillet. Work in batches otherwise the meat won't get nice and caramelized browning.
Step 2: Add the beef, onion, garlic, celery, broth, worcestershire, tomato paste, bay leaves and Italian seasoning to the crock pot. Set to low for 6 hours or high for 4 hours.
Step 3: Halfway through cooking, add your turnips, green beans and carrots. Adding them earlier would give you mushy veggies.
Step 4: After the meat is nice and tender, remove a cup's worth of broth and some veggies.
Step 5: Blend the broth and veggies until smooth. This is your thickener so that this ends up a stew, and not a soup.
Step 6: Add the blended veggie broth mix back to the crock pot to finish off your stew and enjoy!

Description
Blood sugar friendly beef stew with turnips instead of potatoes. All the comfort, none of the glucose spike. Perfect slow cooker family dinner.
Ingredients
- 2-3 lbs (0.9-1.4 kg) chuck beef, cut into 1.5″ (4 cm) cubes
- 1 tsp (3g) paprika
- 1 tsp (6g) salt
- 3 Tbsp (45ml) oil, divided (1 Tbsp for coating beef, 2 Tbsp for browning)
- 1 large onion, halved then cut into ⅖″ (1 cm) slices
- 8 garlic cloves, minced
- 4 celery stalks, cut into 1″ (2.5 cm) pieces
- 3 cups (720ml) beef broth
- 1 Tbsp (15ml) Worcestershire sauce
- 3 Tbsp (45g) tomato paste
- 2 bay leaves, fresh or dried
- 1 tsp (3g) Italian seasoning
- 4 carrots, cut into 1″ (2.5 cm) pieces on the diagonal
- 3-4 large turnips (approx. 25 oz / 710g), cut into chunks
- 8.5 oz (240g) green beans, cut into 1″ (2.5 cm) pieces
- 1 tsp (6g) salt (for finishing)
- ½ Tbsp (7ml) red wine vinegar
Instructions
- In a large bowl, toss the beef cubes with salt, paprika, and 1 tablespoon of oil until evenly coated.
- Heat remaining 2 tablespoons of oil in a large skillet over medium-high heat. Working in three batches so you don’t overcrowd the pan (see note), sear the beef in the hot skillet, 2 minutes per side until browned and then flip to sear the other sides.
- Transfer the seared beef to your slow cooker. Add the onion, garlic, celery, beef broth, Worcestershire sauce, tomato paste, bay leaves, and Italian seasoning. Stir to combine.
- Cook on low for 6 hours or high for 4 hours.
- Halfway through cooking (3 hours on low or 2 hours on high), add the carrots, turnips, and green beans. Continue cooking for the remaining time.
- Once the cook time is up and the beef is tender, remove 1 cup of the cooking liquid along with some vegetables and blend until smooth with a blender. Return the blended mixture to the slow cooker.
- Stir in 1 teaspoon salt and red wine vinegar to add flavor. Add more as desired. Remove bay leaves before serving.
Notes
Overcrowding the pan during the searing process will cause too much moisture to be released at once, preventing browning from happening.
Refrigerate in an airtight container for up to 4-5 days or freeze for up to 3 months in freezer-safe containers or bags. Reheat on the stovetop over medium-low heat, stirring occasionally, until heated through

Frequently Asked Questions
You can skip the browning step and add the beef directly to the slow cooker, but you'll miss out on some flavor depth. The stew will still be delicious, just not quite as rich. If you're in a rush, this shortcut is totally fine!
Absolutely! Brown the beef and prep all vegetables the night before. Store everything separately in the fridge, then combine in the slow cooker in the morning. Don't add the halfway vegetables until it's time though.
Look in the root vegetable section near potatoes, carrots, and onions. They're white with purple tops and about the size of a tennis ball. If your store doesn't carry them, ask the produce manager or opt for rutabagas.
Of course! If blood sugar management isn't a priority, you can absolutely use 3-4 medium potatoes instead of turnips. The cooking time and method remain exactly the same. Just keep in mind you'll lose the blood sugar benefits that make this recipe special.
Fresh vegetables work best for texture, but you can use frozen carrots and green beans. Add them in the last hour of cooking to prevent them from getting mushy. Avoid frozen turnips - they don't hold up well.
Beef stew meat, beef short ribs, or even a bottom round roast work great. Just make sure to cut into similar-sized pieces for even cooking.
The vinegar adds brightness that balances the rich flavors, but you can substitute with lemon juice, regular white vinegar, apple cider vinegar or simply omit it. The stew will still be delicious.
