Ingredients

• 1 lb Lean Ground Beef (90/10 or higher recommended)
• 1 Tbsp Olive Oil (optional, if using lean beef)
• ½ cup Onion, finely diced
• 2 stalks Celery, thinly sliced
• 3 cloves Garlic, minced
• 1 (15 oz) can Diced Tomatoes (do not drain)
• 1 (8 oz) can Tomato Sauce
• 1 tsp Italian Seasoning
• 5 cups Beef Broth (low-sodium preferred)
• ½ cup Diced Green Beans (fresh or frozen)
• Salt and Freshly Cracked Pepper, to taste
• Optional Topping: Shredded Sharp Cheddar Cheese or Fresh Parsley

Instructions (Stovetop Method)

1. Sauté Aromatics: Heat the olive oil (if using) in a large pot or Dutch oven over medium-high heat. Add the onion and celery. Cook for 5–6 minutes until softened.
2. Brown Beef: Add the ground beef to the pot. Season lightly with salt and pepper. Cook, breaking up the ground beef with a spoon, until browned and mostly cooked through. Add the minced garlic and cook for 30 seconds more.
3. Simmer Base: Add the diced tomatoes (undrained), tomato sauce, Italian seasoning, and beef broth to the pot. Bring the mixture to a simmer.
4. Cook and Finish: Cook the soup for 25–30 minutes. Stir in the diced green beans and cook for 5–10 minutes more, or until the green beans are tender-crisp.
5. Serve: Taste and season with additional salt and pepper if needed. Serve the easy tomato beef soup immediately, garnished with shredded cheese and fresh parsley.

Storage and Expert Tips

• Ground Beef Fat: If using high-fat ground beef (80/20), drain off the excess fat after browning the meat (Step 2) to prevent a greasy soup. If using lean beef, no draining is necessary.
• Low-Carb Boost: For a heartier, low-carb soup, stir in 1 cup of riced cauliflower during the last 10 minutes of simmering. It absorbs the broth flavor beautifully.
• Best Toppings: This soup is excellent topped with shredded sharp cheddar cheese and a dollop of sour cream—the classic “loaded” experience.
• Simmer Time: Allowing the soup to simmer for the full 25–30 minutes is key to blending the tomato and beef broth flavors.

Variations

• Spicy Kick: Add ¼ teaspoon of cayenne pepper or a dash of hot sauce along with the Italian seasoning.
• Vegetable Boost: Add sliced mushrooms, diced zucchini, or frozen mixed vegetables during the main simmer (Step 3).
• Instant Pot: Brown the beef/onions on Sauté mode. Add remaining ingredients (except cheese). Pressure cook on Manual/High for 10 minutes, then Quick Release. Stir in green beans and simmer for 5 minutes.

Frequently Asked Questions

Q: Can I use vegetable broth instead of beef broth? A: Yes. You can substitute vegetable broth for beef broth, but the flavor will be less robust and meaty. Add 1 teaspoon of Worcestershire sauce or mushroom powder to deepen the savory, umami flavor.

Q: Can I add potatoes or pasta to this hamburger beef soup? A: Yes, if you don’t need a low-carb version. Add ½ cup of diced potatoes or small pasta (like elbow macaroni) at the beginning of the simmer (Step 4). You may need to increase the beef broth by 1 cup to compensate for absorption.

Q: How long does this low carb beef soup last as leftovers? A: This soup is freezer-friendly and holds well in the refrigerator. Store leftovers in an airtight container for up to 3 days in the fridge, or freeze for 1–2 months.

Q: How do I make the broth thicker without adding starch (flour)? A: To naturally thicken the keto friendly soup ground beef recipe, remove about 1 cup of the broth and vegetables, blend them until smooth, and stir the purée back into the pot.
