Ingredients Method

Ingredients

  

• 1 pound (450 g) beef stew meat, cut into small, bite-size pieces
• 2 tablespoons olive oil or avocado oil
• 1 medium onion, diced
• 3 cloves garlic, minced
• 2 medium carrots, sliced thin (optional for strict low-carb; see notes)
• 2 celery stalks, sliced
• 2 cups cauliflower florets, cut small
• 1 cup green beans, trimmed and cut into 1-inch pieces
• 1 medium zucchini, chopped
• 1 (14.5 oz/400 g) can diced tomatoes, no sugar added
• 6 cups beef broth (low-sodium if preferred)
• 2 tablespoons tomato paste
• 1 teaspoon dried thyme
• 1 teaspoon dried oregano
• 1 teaspoon smoked paprika (optional but recommended)
• 1 bay leaf
• Salt and black pepper, to taste
• Fresh parsley, chopped, for garnish

Method

 

1. Season and brown the beef. Pat the beef dry and season generously with salt and pepper. Heat the oil in a large pot or Dutch oven over medium-high heat. Add the beef in a single layer and brown on all sides, working in batches if needed. Don’t rush this step—browning builds deep flavor.
2. Sauté the aromatics. Reduce heat to medium. Add the onion and celery to the pot and cook 3–4 minutes until softened, scraping up any browned bits. Stir in the garlic and cook 30 seconds until fragrant.
3. Add tomato base and spices. Stir in the tomato paste, thyme, oregano, and smoked paprika. Cook 1 minute to caramelize the paste slightly. This step gives the broth a richer, rounder taste.
4. Build the soup. Return the browned beef (and any juices) to the pot. Add the diced tomatoes, beef broth, bay leaf, carrots (if using), cauliflower, and green beans. Bring to a gentle boil.
5. Simmer until tender. Reduce heat to low, cover, and simmer 35–45 minutes, or until the beef is tender and the vegetables are soft but not mushy. Stir occasionally and adjust seasoning with salt and pepper.
6. Finish with zucchini. Add the chopped zucchini in the last 10 minutes of cooking so it stays bright and slightly firm.
7. Taste and serve. Remove the bay leaf. Taste and adjust seasoning. Ladle into bowls and garnish with fresh parsley. For extra richness, stir in a knob of butter or a drizzle of olive oil before serving.

What Makes This Special

Save

This soup keeps things simple while staying big on flavor.

It uses everyday ingredients, but the method builds depth: browning the beef, sautéing aromatics, and simmering everything until it’s perfectly tender. It’s naturally low in carbs thanks to smart swaps like cauliflower and green beans instead of potatoes and corn. And because it’s a one-pot recipe, cleanup is quick and painless.

It’s the kind of meal you can make on a weeknight and still feel like you treated yourself.

What You’ll Need

• 2 celery stalks, sliced
• 2 cups cauliflower florets, cut small

Notes on carbs: Carrots add a touch of sweetness and a few extra carbs. For the lowest carb count, reduce or omit the carrots and add more celery or zucchini instead.

Instructions

1. Season and brown the beef. Pat the beef dry and season generously with salt and pepper. Heat the oil in a large pot or Dutch oven over medium-high heat.

   Add the beef in a single layer and brown on all sides, working in batches if needed. Don’t rush this step—browning builds deep flavor.

2. Sauté the aromatics. Reduce heat to medium. Add the onion and celery to the pot and cook 3–4 minutes until softened, scraping up any browned bits. Stir in the garlic and cook 30 seconds until fragrant.
3. Add tomato base and spices. Stir in the tomato paste, thyme, oregano, and smoked paprika.

   Cook 1 minute to caramelize the paste slightly. This step gives the broth a richer, rounder taste.

4. Build the soup. Return the browned beef (and any juices) to the pot. Add the diced tomatoes, beef broth, bay leaf, carrots (if using), cauliflower, and green beans.

   Bring to a gentle boil.

5. Simmer until tender. Reduce heat to low, cover, and simmer 35–45 minutes, or until the beef is tender and the vegetables are soft but not mushy. Stir occasionally and adjust seasoning with salt and pepper.
6. Finish with zucchini. Add the chopped zucchini in the last 10 minutes of cooking so it stays bright and slightly firm.
7. Taste and serve. Remove the bay leaf. Taste and adjust seasoning.

   Ladle into bowls and garnish with fresh parsley. For extra richness, stir in a knob of butter or a drizzle of olive oil before serving.

Storage Instructions

• Refrigerator: Cool completely, then store in airtight containers for up to 4 days.
• Freezer: Freeze in portioned containers for up to 3 months. Leave a little headspace for expansion.
• Reheating: Warm gently on the stove over medium-low heat or in the microwave.

  If thickened after chilling, add a splash of broth or water to loosen.

• Meal prep tip: Store zucchini separately if you plan to keep the soup more than 3 days. Add it fresh when reheating for the best texture.

Benefits of This Recipe

• Low in carbs, high in satisfaction: Smart vegetable choices keep carbs down while still offering plenty of volume and fiber.
• Protein-packed: The beef brings staying power, making this a filling lunch or dinner.
• One pot, minimal cleanup: Everything simmers together, so you spend more time relaxing and less time washing dishes.
• Flexible and forgiving: Swap vegetables based on what you have. The broth and spices keep it flavorful either way.
• Great for leftovers: The flavors deepen overnight, making it ideal for meal prep.

What Not to Do

• Don’t skip browning the beef. It’s tempting to rush, but searing is where much of the flavor comes from.
• Don’t add zucchini too early. It can overcook and turn mushy; add near the end.
• Don’t overload with starchy vegetables. Potatoes, peas, and corn hike up carb counts quickly.
• Don’t forget to taste as you go. Low-sodium broths vary.

  Adjust salt, pepper, and acidity to balance the flavors.

• Don’t boil aggressively. A gentle simmer keeps the beef tender and the vegetables intact.

Variations You Can Try

• Italian-style: Add 1 teaspoon Italian seasoning, a pinch of red pepper flakes, and finish with grated Parmesan.
• Mexican-inspired: Use cumin and chili powder in place of oregano and thyme. Add a squeeze of lime and chopped cilantro at the end.
• Mushroom boost: Add 2 cups of sliced mushrooms for extra umami with minimal carbs.
• Leafy greens: Stir in chopped kale or spinach during the last 5 minutes for added nutrients.
• Different proteins: Try ground beef, leftover roast, or thinly sliced flank steak. Adjust simmer time as needed.
• Bone broth base: Swap in bone broth for extra collagen and a richer mouthfeel.
• Spicy kick: Add a diced jalapeño with the onions or a dash of hot sauce at the end.

FAQ

Is this soup keto-friendly?

Yes, with a small tweak.

Omit or reduce the carrots to lower the carb count further, and stick to non-starchy vegetables like cauliflower, zucchini, and green beans. Always check your broth and tomatoes for added sugars.

Can I make it in a slow cooker?

Absolutely. Brown the beef and sauté the aromatics on the stove first, then transfer everything (except zucchini) to the slow cooker.

Cook on Low for 6–8 hours or High for 3–4 hours. Add zucchini in the last 30–45 minutes.

What cut of beef works best?

Beef stew meat, chuck roast cut into cubes, or even short rib meat works well. Choose a cut with some marbling to keep it tender and flavorful during the simmer.

How can I thicken the soup without flour?

Simmer uncovered for the last 10–15 minutes to reduce the broth slightly.

You can also mash a few cauliflower florets against the side of the pot to give the soup a creamier body.

Can I make it without tomatoes?

Yes. Skip the diced tomatoes and tomato paste. Add an extra cup of broth and a splash of balsamic vinegar or a squeeze of lemon for brightness.

Consider adding more herbs and a pinch of paprika to round out the flavor.

How do I keep the beef from getting tough?

Use a gentle simmer, not a rolling boil, and give it enough time. Toughness usually means it needs either more time to break down or the heat is too high. Chuck and stew cuts reward patience.

What sides go well with this?

A simple green salad, roasted Brussels sprouts, or a slice of low-carb bread works nicely.

For something extra cozy, serve with a dollop of sour cream or a sprinkle of Parmesan on top.
