Ingredients
For the Keto Meatballs:
- 1/2 lb ground beef (93/7) (225g, lean for optimal texture)
- 1/2 lb ground Italian sausage (225g, adds authentic flavor depth)
- 1/2 cup pork panko (ground pork rinds, zero-carb breadcrumb substitute)
- 1 large egg (binds ingredients together)
- 1/3 cup grated parmesan cheese (adds umami and binding power)
- 3 cloves garlic, minced (fresh for best flavor)
- 2 tablespoons finely chopped fresh parsley
- 1 teaspoon dried oregano
- 1 teaspoon salt
- 1/2 teaspoon black pepper
For the Soup Base:
- 3 tablespoons olive oil (for browning meatballs)
- 1/2 medium yellow onion, chopped (sweet foundation flavor)
- 1 carrot, sliced (adds natural sweetness and nutrients)
- 3 stalks celery, sliced (classic soup base vegetable)
- 3 cloves garlic, minced
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 8 cups chicken broth (homemade preferred for richest flavor)
- 1 cup lupini rice (low-carb orzo substitute)
- 3 cups baby spinach leaves (the "bride" to the meatball "groom")
Detailed Instructions
Preparing the Meatball Mixture
- Combine all meatball ingredients in a large mixing bowl. Add the ground beef, Italian sausage, pork panko, egg, parmesan cheese, minced garlic, chopped parsley, oregano, salt, and pepper.
- Mix until just combined using a spoon or clean hands. Don't overmix – this keeps the meatballs tender. The mixture should hold together when squeezed but not feel dense or packed.
Forming Perfect Mini Meatballs
- Scoop and roll small meatballs using a heaping teaspoon of mixture for each. Roll between your palms to form balls about 3/4 to 1-inch in diameter. You should get 75-80 meatballs – they need to be small enough to fit on a spoon and eat in one bite.
- Place formed meatballs on a large plate or baking sheet as you work. This assembly-line approach speeds up the process.
Browning the Meatballs
- Heat olive oil in a large Dutch oven over medium heat. The oil should shimmer but not smoke – this indicates the perfect temperature for browning.
- Brown meatballs in batches to avoid overcrowding. Cook 3-4 minutes per batch, turning to brown all sides. The meatballs don't need to cook through completely – just develop a golden-brown crust that seals in flavor.
- Transfer browned meatballs to a paper towel-lined plate. Don't clean the pot – those brown bits are flavor gold!
Building the Soup Base
- Sauté the vegetables in the same Dutch oven with remaining oil and brown bits. Add onion, carrot, and celery, stirring occasionally until slightly tender, about 5-6 minutes.
- Add garlic and seasonings, stirring constantly for 1 minute until fragrant. The garlic should sizzle but not burn – this releases its full aromatic potential.
Bringing It All Together
- Return meatballs to the pot and pour in chicken broth. Bring to a simmer over medium-high heat – you'll see gentle bubbles breaking the surface.
- Add lupini rice and reduce heat to maintain a gentle simmer. Cook 6-8 minutes, stirring occasionally, until the rice is tender but still has a slight bite.
- Finish with spinach by removing from heat and stirring in the baby spinach leaves until wilted, about 1-2 minutes. Taste and adjust seasoning with additional salt and pepper if needed.
Chef's Tips for Success
- Don't skip the browning step – those caramelized bits on the meatballs and in the pot create the deep, rich flavor that makes this soup restaurant-quality
- Size matters for meatballs – keep them small and uniform for even cooking and proper spoon-to-mouth ratio in each bite
- Use fresh garlic over powder – minced fresh garlic provides aromatic oils that dried garlic simply can't match
- Quality broth makes the difference – homemade or high-quality store-bought chicken broth elevates the entire soup; avoid overly salty or artificial-tasting options
- Add spinach at the very end – removing from heat before stirring in spinach prevents overcooking and maintains vibrant color and texture
Nutritional Benefits
Compared to traditional Italian wedding soup loaded with pasta and breadcrumb-heavy meatballs, this keto version delivers superior nutrition without sacrificing comfort. Each serving provides over 40 grams of complete protein while keeping net carbs under 8 grams, making it perfect for ketogenic, low-carb, or high-protein eating plans.

Storage and Serving
Store leftover soup in the refrigerator for up to 4 days in airtight containers. The flavors actually improve overnight as the spices meld and the meatballs absorb more of the savory broth. Reheat gently on the stovetop over medium-low heat, adding a splash of broth if needed to restore consistency.
Serve hot in warmed bowls topped with freshly grated parmesan cheese and a sprinkle of chopped parsley. This soup pairs beautifully with keto garlic bread or a simple side salad for a complete comfort meal that won't compromise your health goals.

FAQ Section
Q: Can I substitute the ground Italian sausage with another meat?
A: Yes! Ground turkey, chicken, or even all beef work well. Italian sausage adds distinctive fennel and herb flavors, so consider adding 1/2 teaspoon fennel seeds and extra oregano if using plain ground meat.
Q: What can I use instead of pork panko if I can't find it?
A: Crushed pork rinds, almond flour (use 1/3 cup), or finely grated parmesan cheese work as substitutes. Each will create slightly different textures, but all bind the meatballs effectively.
Q: How do I prevent my meatballs from falling apart during cooking?
A: Don't overmix the meat mixture, ensure your oil is properly heated before adding meatballs, and avoid moving them too quickly. Let each side develop a proper crust before turning.
Q: Can I make this soup in a slow cooker?
A: Absolutely! Brown the meatballs first, then add everything except spinach to the slow cooker. Cook on low 6-8 hours or high 3-4 hours. Stir in spinach during the last 10 minutes.
Q: Is lupini rice necessary, or can I use other low-carb alternatives?
A: Cauliflower rice, shirataki rice, or even small cauliflower florets work as substitutes. Cook times will vary – cauliflower rice needs only 2-3 minutes, while shirataki should be rinsed and drained first.
Q: How long will this soup keep in the freezer?
A: Freeze for up to 3 months in freezer-safe containers. Note that the texture of lupini rice may change slightly after freezing. Thaw overnight in refrigerator before reheating.
Q: My soup turned out too salty. How can I fix it?
A: Add more unsalted broth to dilute, stir in some heavy cream to balance flavors, or add extra spinach and lupini rice to absorb excess salt. Always taste and adjust seasoning gradually.
Q: Can I make this dairy-free?
A: Replace parmesan cheese in meatballs with nutritional yeast (2 tablespoons) and skip the garnish cheese. The flavor will be slightly different but still delicious.
