Why This Recipe Works

Ultra-tender beef in under 90 minutes: A combination of searing for Maillard-depth and pressure-cooking for collagen-breakdown yields fork-soft cubes without an all-day simmer.
Low-carb, not low-flavor: Tomato paste, Worcestershire, and a whisper of smoked paprika build umami layers usually supplied by starchy thickeners.
One pot, zero fuss: From browning to final simmer, everything happens in the same heavy Dutch oven—less dishes, more Netflix.
Freezer hero: Make a double batch; it reheats like a dream and tastes even better the next day when the flavors meld.
Kid-approved vegetables: The radishes lose their peppery bite and look just like little potatoes, so even picky eaters spoon them up.
Macro-balanced: 31 g protein, 7 g net carbs, 22 g fat keeps you in ketosis while satisfying that “I need something hearty” craving.

Ingredients You'll Need

Great stew starts at the butcher counter. Ask for well-marbled chuck roast; the intramuscular fat translates to beef that practically dissolves on your tongue. If you can, buy the roast in one piece and cube it yourself—pre-cut “stew meat” is often odds and ends of varying sizes that cook unevenly. Aim for 1-inch cubes: large enough to stay juicy, small enough to eat gracefully with a soup spoon.

Avocado oil is my go-to high-heat neutral fat for searing. Its mild flavor lets the beef shine, and the smoke point north of 500 °F means no bitter burnt notes. Olive oil works in a pinch, but keep the heat closer to medium-high.

Radishes are the stealth ingredient here. Choose firm, golf-ball-size specimens; larger radishes can be woody. A quick peel removes any surface bitterness, and a 20-minute simmer tames their pepper into a gentle, almost turnip-like sweetness.

For the broth, I reach for homemade bone broth whenever possible—rich in minerals and collagen that lend body without thickeners. If you’re grabbing store-bought, look for one labeled “beef bone broth,” not just “beef stock.” Kettle & Fire or Bonafide Provisions are my favorite widely available brands with zero added sugar.

Tomato paste in a tube is a pantry MVP; it stays fresh for weeks and lets you use just the tablespoon you need. Double-concentrated Italian versions give deeper flavor for the same carb count.

Worcestershire sauce adds anchovy-driven complexity. Check labels—some bargain brands sneak in molasses. Lea & Perrins Original in the U.S. lists 1 g carbs per teaspoon, perfectly acceptable for our uses.

Smoked paprika (pimentón dulce) gives a whisper of campfire without heat. If you only have regular sweet paprika, add a pinch of ground cumin to mimic the smokiness.

Fresh herbs are worth the splurge. Woody thyme stems infuse the braising liquid; strip the leaves at the end for bright pops of flavor. Flat-leaf parsley stirred in right before serving adds a fresh, grassy lift that balances the rich broth.

How to Make Hearty Keto Beef and Vegetable Stew for a Filling and Nutritious Meal

Pat, season, and sear the beef

Thoroughly dry the cubed chuck with paper towels—moisture is the enemy of browning. Season generously with 1 ½ teaspoons kosher salt and ½ teaspoon black pepper. Heat 2 tablespoons avocado oil in a 5- to 6-quart Dutch oven over medium-high until shimmering. Working in two batches (crowding = steaming), sear the beef until a mahogany crust forms on two sides, about 3 minutes per side. Transfer to a bowl. Don’t rinse the pot; those browned bits are liquid gold.

Build the aromatic base

Lower heat to medium. Add remaining tablespoon oil, diced onion, celery, and a pinch of salt. Sauté until edges turn translucent, 4 minutes. Stir in minced garlic for 30 seconds, then tomato paste, smoked paprika, and Worcestershire. Cook 1 minute, scraping so the paste toasts but doesn’t burn—the mixture will darken and smell like Sunday gravy.

Deglaze with vinegar and broth

Pour in balsamic vinegar; it will hiss and steam. Use a wooden spoon to lift every last fleck of fond. Add 3 cups broth, thyme sprigs, and bay leaf. Return beef plus any juices. Liquid should just cover the meat; add a splash more broth or water if needed.

Pressure-cook or simmer

If using an Instant Pot, secure lid, set to Meat/Stew on high for 35 minutes with natural release 10 minutes. For stovetop, bring to a gentle boil, cover, and reduce to low; simmer 1 hour 15 minutes, stirring once halfway. Either way, the beef should yield easily to the tip of a paring knife.

Add vegetables and finish

Remove thyme stems and bay leaf. Stir in radish quarters and cauliflower florets. Simmer uncovered 15–20 minutes, until radites are tender and broth has reduced slightly. If you prefer a thicker stew, ladle ½ cup liquid into a small bowl, whisk in ½ teaspoon xanthan gum, then stir back into pot and simmer 2 minutes.

Season and serve

Taste and adjust salt and pepper. Stir in chopped parsley for brightness. Ladle into warm bowls, drizzle with a swirl of extra-virgin olive oil or a spoon of sour cream if desired. Leftovers keep 4 days refrigerated or 3 months frozen.

Expert Tips

Flash-freeze individual portions

Ladle cooled stew into silicone muffin molds; freeze until solid, then pop out and store in a zip bag. Reheat one or two “pucks” for a speedy solo lunch.

Deglaze with red wine

Swap ½ cup broth for dry red wine for deeper flavor. Let it bubble 2 minutes to cook off alcohol before adding remaining liquid.

Speed it up with ground beef

In a hurry? Brown 1½ lb 80% lean ground beef, break into chunks, and proceed with aromatics. Total cook time drops to 30 minutes.

Herb stem trick

Don’t toss thyme stems—after simmering they slip right off, and the tiny leaves stay behind, infusing every bite.

Overnight flavor boost

Make the stew through step 4, then refrigerate overnight. Next day skim the congealed fat, add vegetables, and simmer—tastes like it cooked twice as long.

Thicken without carbs

For a glossy gravy-like finish, blitz ½ cup of the finished stew (veggies and liquid) with an immersion blender and stir back in—pure vegetable power.

Variations to Try

Mexican-Inspired: Swap smoked paprika for chipotle powder, add 1 tsp cumin, and finish with cilantro and a squeeze of lime. Top with diced avocado.
Mushroom Lovers: Stir in 8 oz sliced cremini mushrooms during the last 10 minutes of cooking for an earthy boost and extra B vitamins.
Green Veg Boost: Add 2 cups chopped kale or spinach in the final 3 minutes; they wilt instantly and keep the color vibrant.
Seafood Spin: Replace beef with 1 lb wild salmon chunks added in the last 5 minutes, and swap beef broth for fish stock. Finish with dill.

Storage Tips

Refrigerate

Cool completely, transfer to airtight glass jars, and refrigerate up to 4 days. Reheat gently over medium-low, adding a splash of broth to loosen.

Freeze

Chill stew in quart-size freezer bags laid flat for space-saving stacks. Freeze up to 3 months. Thaw overnight in fridge or 5 minutes under cool water.

Reheat

Microwave 2-3 minutes at 70% power, stirring halfway, or simmer on stovetop 5 minutes until center hits 165 °F. Add a pat of butter for extra richness.

Frequently Asked Questions

Yes, but adjust cook time. Sirloin will become dry with long braising—use it only if you’re pressure-cooking 20 minutes. Brisket works beautifully; slice across the grain first for shorter strands that soften faster.

Peeling is optional. A quick scrape removes any surface bitterness, but if your radishes are young and blemish-free, simply scrub and quarter. The skins soften and turn rosy in the broth.

The recipe is naturally dairy-free. Skip optional sour-cream garnish or substitute coconut cream for a luscious swirl.

Almost—just be sure your Worcestershire and broth have no added sugar or malt vinegar. The Primal Kitchen brand Worcestershire is Whole30 approved.

Absolutely. Use an 8-quart pot or divide between two 6-quart pressure cookers. Increase natural release to 15 minutes. Freeze half for a future no-cook night.

No problem—simmer the stew uncovered an extra 5–7 minutes to reduce, or stir in 2 tablespoons of almond flour slurry (1:1 with water) and cook 2 minutes for a gentle thickener.
